Hydraulic splitters for any budget
Splitter hydraulic or splitter - means automation firewood. Most often, a hydraulic cleaver called "Cleaving". And it created many models of hands of domestic craftsmen and skilled engineers.
Wood splitters, mechanical and hydraulic use in private households or in small manufacturing plants for wood processing. The machines operate anywhere mechanical crosscutting and splitting wood of different species.
Hand tool for splitting and bucking often breaks down, and requires skill, effort and time. Machines and other installations, non-hydraulic type often break down due to uneven loading.
Hydraulic wood splitters, made at the factory or by the hands, not because of advertising are gaining in popularity. The fact is that any apparatus of the type of load, as high as 10 tons, are fed gradually with an increase in strength. That keeps the engine, and the oil pump from overload and breakage.
Construction equipment market offers several dozen models of hydraulic wood splitters in the price range from 10 to 200 thousand rubles. It is important to know that the price depends on:
- type of engine;
- maximum length of the log;
- voltage (model with an electric motor).
Power supply for the engine are divided into 2 categories.
Motor. This power converter has an effect on the pump. Moreover, the electric motor used in the most primitive, household machines. Serve these models are very simple, and use the same garage or barn can be, given the environmental safety. Collected his own hands or in the shop, models with electric motors the easiest way to prepare for the work, even allowed to carry by hand. The main disadvantage - not function without power.
Gas engine. Mounted on a powerful model that can be transported to the place of firewood. Splitter of gasoline, as a rule, harder, more expensive and more powerful. But he and functional thanks to the mobility and more power.
The most commonly used for domestic purposes in the preparation for the heating season. And the level of engineering agricultural worker can encourage the creation of consumer and professional equipment.
In this case, domestic everything is clear, but a professional machine can be operated in line. Simply put, still have a supply function, trim, discharge.
Everyone independently to create a similar setup to facilitate the work can be found on the network with the drawings, diagrams and video instructions. An example of a good hydraulic cutters, and harvested their own hands, will this video:
What is included in the design of hydraulic woodsplitter?
Hydraulic firewood processor, created with his own hands must consist of certain parts. Be part of the best in importance, and start from:
- a cylinder lock;
- a wedge-shaped blade (or blades);
- fluid pressure distributor;
- oil tank;
- engine or motor.
The easiest way to collect the firewood begins working with welding frames, to be mounted on the platform. The lower part of the platform is equipped with a car jack (at least).
In the upper part of the frame is required to calculate connector. He needs to pick chocks of different diameters and lengths.
Splitter on the photo created with his own hands, but already designed on an industrial scale. In its more complex construction which is required to consists of a hydraulic jack on the stationary frame (literal) type. Creating this installation requires plumbing skills, calculation safety. Suppose that, at first glance, the unit and is not complicated, but working with the negligence of the operator will sooner or later an accident.
Due to the savings in time and resources have been created wedge-shaped knives with blades 4-8. The fact that a standard knife chock divides into 2 parts, as this model handles in one go any log.
Hydraulic firewood processor, made by hand, this increase in power (the drive from the tractor, gasoline engine) must be equipped with a wedge-shaped knife with 4 blades, at least.
How to make a cleaver
Firewood requires considerable effort: they need to saw, chop, add to Accessories for drying. Most power goes out to chop firewood. Facilitate and accelerate the process may cleaver. They are represented in sufficient numbers, but are respectable money. At the same time, to make the simplest cleaver own hands can be of metal - pipes, corners, etc. All require literally thousands - if not metal, it will have to buy.
If the volume of firewood are small, they are easy to handle mechanical cleaver. They are characterized by simplicity of design, the minimum number of complex assemblies, as well as the fact that the costs are minimal, even if the economy is not suitable piece of iron.
The easiest and safest option. The only pity poor performance. but safe
Simple cleaver own hands: mechanic
The simplest mechanical resembles a cleaver sump crane. The design of one to one, but instead of buckets fixed cutter and a handle. The connection supports (pillars) and the beam can be made most simple - hinge. Only need good lubrication.
The principle of operation is probably all clear. Block of wood put on the stand, sharply pull down the lever, due to the inertia force tool is gaining significant power and splits the block of wood. The process is repeated as long as will not produce the desired thickness of the logs.
The easiest cleaver collect their own hands can be of several pipes
Such a mechanical cleaver with his hands just to collect, and, literally, from the fact that there is - pipes, angles of any size, even an ax can be used as a torch. In addition, such a design can be made collapsible - to be able to tolerate it.
Many minuses. FIREWOODPROCESSORS requires considerable effort. And the more effort is exerted to stop the move cleaver after a log fell apart. Another minus - like cleaver occupies a substantial area, because the longer the lever, the less effort it is necessary to apply. Nevertheless, even such a primitive mechanical device is much reduces the complexity of the process.
One option - Cleaving is welded to the square pipe grouted
In this configuration splitter should be heavy. Because the blade itself is welded to the all-metal ingot. More affordable option - be welded to the tube (round or square) and fill it with concrete. Agree to make such a cleaver with his hands on forces anyone who knows how to handle the welding machine.
There is a modified design of the manual mechanical cutters, and which, in a smaller, chopping wood better, requires less effort. In this model, the main operating unit - a spring which is fixed on the frame, and the upper part rests on the fixed crossbeam, on which there is fixed splitter.
The design of the spring woodsplitter
In this construction, the main effort - hold Cleaver after log split - assumes the spring. Accordingly, the main thing - to choose the spring and focus so that minimal force were applied, but they were enough to crack even complex, knotted block of wood. The emphasis under the spring can be made movable. Then you can adjust the settings to suit the specific conditions. In reality, the "resetting" is required for a particular person. If you work with an instrument will be one person, we can do everything stationary, picking height empirically.
It is equally important to make movable articulation of the frame and lever, which is mounted splitter. The best option - bearings. They must be of good quality, it is desirable - self-leveling.
Ready homemade spring cleaver
The minimum height of homemade woodsplitter - about 800 mm. But then you have to work or stooping, or install the machine on a table / base frame. A more comfortable alternative requiring minimal effort - made for its growth. Determine at what height you are comfortable to stand on a log, add to this figure the height of the block of wood, get the height of the frame. In this case, too, will have to bend, but only when installing the chock on the stand, and not every time the ax falls.
To add mobility design, cook a frame, on the one hand a fixed wheel, the second welded stops. Make a cleaver with his hands a bit more complicated, but if there is a spring and bearings - and it is such a difficult task.
Splitter inertial vertical
Another simple option for independent production. To make such a cleaver with his hands need two tubes of larger and smaller diameter. Another need heavy plate - a base, and, in fact, stitching part - cutter / splitter.
Construction - one of the most simple, requires little effort. On a massive platform secured a thick-walled pipe, but better - the pin. Height - about one meter. It is the leading pipe. As it moves freely splitter, which is welded to the pipe rings of slightly larger diameter than the lead pipe. He chops wood as follows: pick up the ax and let him go. You can give a little downward acceleration. By gravity log splitting.
But this mechanical cleaver splits once not all the block of wood. To increase its effectiveness, on the splitter can be done weighting. It is possible to "add" if necessary. The second option - hit a couple of times over the column with a hammer. This method is good if the tool is stuck in the wood. The alternative - to lift up and block of wood with sharply lower. But hammer wave easier.
Handheld cleaver, of course, makes it easier to get firewood, but still requires a solid physical effort. Not as much as they spend waving the usual cleaver, but still ... Make an effort even lower helps motor. On its basis, wood splitters make different designs. But to make such a cleaver with his hands more difficult. And then the device is more complicated and requires at least minimal knowledge of electrical -zhelatelno connect the motor through a starter, and with the "Start" button and "start".
One of the most popular models - tapered screw or cleaver. The difference between them is only in the absence / presence of the thread on the pricking element, which in this model is in the form of a cone.
Conical cleaver accelerates firewood
Block of wood split by the fact that the rotating motor cone cuts into the wood, slowly tearing apart. In a large block of wood chips first edge and then tear the middle.
First machined cutting part in the form of a smooth cone. If you use a smooth cone at the falls is quite lean on the block of wood to the cylinder 'bite' into the wood. It is much easier to process if threaded on its surface. In this case, block of wood, as it were screwed onto the screw, and then split.
Dimensional drawing cone threaded for screw woodsplitter
The main thing - the right to make a cone with thread. If you have a lathe and experience you can try to make yourself. If not - will have to be ordered. Thread to do different, but optimal recognized the following parameters: Step 7 mm, depth 3 mm (minimum - 2 mm). Another important point - the depth of the seat of the motor reducer - not less than 70 mm.
If a cone threaded, make the cleaver with his hands in the cellar.
Needed sufficiently powerful electric motor (2 kW or higher, or 5.9 l / s), but with a slight speed: 250-600 revolutions / min. At 250 rpm and below the tunic very slowly, and if speed is more than 500 - work is dangerous, that it may pull out a piece of wood out of hand.
Splitter with screw, wear directly on the crankshaft
If unable to find the engine with such parameters can be made peak (screw) to impose directly on the crankshaft (pictured above). If the speed is greater need to set a reduction gear or to make a chain or belt drive to reduce speed.
The ratio is calculated as a function of engine speed. For example, there is the engine for 900 revolutions. Having reducer 1: 2 obtain 450 revolutions / min. Just the best option.
Reduction gear for screw woodsplitter
Transmissions can be belt or chain. Continued work at times louder require constant strokes, and carve asterisk stands with the necessary parameters are usually more expensive. Double belt drive is desirable (as pictured above). In this case, the smaller will be the slippage.
If the design provides for the transmission, the motor is better to put at the bottom, and the screw is fixed on the work surface. Select the height of the work surface under its growth, it was not necessary to work in the slope.
Safer model. Make a cleaver with his hands - significantly simplify your life
There is still such a parameter as the height of the rotor above the work surface. The gap from the table to the cylinder must be in the region of 8-20 cm above the positioning is not necessary -. Can turn the block of wood of small diameter. Optimal distance -. 8-12 cm Even small-size block of wood does not turn.
Hydraulic cleaver - the most powerful but also the most complex and expensive to manufacture. In addition to the frame, the engine and the cutting knives need a hydraulic cylinder of sufficient capacity. Are they are not cheap. In addition, we need more oil tank and pump.
Apparatus hydraulic cleaver
Hydraulic firewood splitter develops solid efforts during its manufacture because metal is used a considerable thickness - 6.10 mm, depending on drive power. Force that is enough to at once destroy the chock 6-8 logs. Because the blades are made in the form of a "star".
Log splitter with hydraulically fitted with sophisticated cutter block of wood that falls apart into several logs at once
In the manufacture of knives spaced from each other by a few centimeters. So that the work was only one. For example, the first - horizontal, then - vertical, then - right at the end - left. Thus, each of the blades amplifies, privarivaya rear reinforcing plate. Steel is desirable to use a rigid, pre-confining it in the same way as in the splitter.
Gasoline cleaver works quite quickly, though hemp birch. I had to chop using colon elm - this is where the real confusion, ax stuck in the wood. Judging from the video, gasoline cleaver has to cope with an elm.
Hydraulic cleaver. Fast firewood
Not far off the autumn. And, if your country house is heated by solid fuel boilers, it's time to think about firewood. With a large volume of heated space mechanized harvesting is clearly preferable in terms of performance than a conventional ax. Hydraulic firewood processor (or, alternatively, a hydraulic splitter) - a good solution to the problem.
Species and the principle of operation of the hydraulic woodsplitter
Immediately it should be noted that the mechanization of the process of obtaining the wood can be a different way - for example, using a screw cleaver with electric or manual drive. However, the hydraulic drive allows the preliminary pressing of the log that will secure a job with the wood splitters and ensures better digestion. Washing pump unit typically produced by an electric power of 3 ... 6 kW, or by the gasoline engine.
Drive hydraulic woodsplitter can have two versions - horizontal and vertical. Both are applicable, all determined by the availability of free space on a plot of farm buildings, and - in the case of the manufacture of hydraulic cleaver with his hands - the availability of existing pumping plant, which is expected to use.
Note that the vertical unit is equipped with a frame with wheels that allows you to move it to the site. Representation of the design can be improved by using instead of the usual flat blade tool with X-like blade, which would divide the cormorant is not two, but into four fragments.
With control gidrodrovokola vertical type can easily handle one man at the height of the original logs are limited to the dimensions of the frame. It is believed that the longitudinal driving stability during such an arrangement is reduced, so power model hydraulic wood splitters vertical type horizontal inferior to their "colleagues". To drive the device can use any hydraulic wheeled tractor, and a circuit diagram will differ little from that shown in Fig.
The starting points of the industrial execution selecting an appropriate model are:
- The pressure generated on the end of a cleavable log. Depending on the model of the unit is the pressure varies in the range of 100 ... 200 bar, that in terms of force gives about 60 ... 80 kN. Experts believe that these design parameters is enough to chop wood logs of conventional diameter of 45 ... 50 mm (oak, redwood, hornbeam and m. P. Exotic understood excluded).
- Piston stroke. Typically manufacturers provide a working piston displacement (to which the stem is attached wedge) within 200 ... 400 mm, with a two-speed drive: on the forward stroke of 30 ... 80 mm / s, to return 100 ... 150 mm / s.
- Type of drive. It depends on the specific conditions of the user. When the power supply of instability better focus on petrol or diesel engines. Power consumption, depending on the type of pump unit is 2 ... 4 kW.
- Additional options, the most important of which are considered mobility installation height setting splits preform, the presence of the control valve (to reduce electricity costs during the return movement rod), and the control principle (variant with two levers safer as the operator's hands are out of the working area).
An important component of the selection and the price is a hydraulic woodsplitter. offers the market is vast, ranging from units of domestic production, the price of which starts at 100,000 ... 140,000 rubles to the hydraulic Cleaver imported (products listed by brands Sple, Lancman), which cost up to 280,000 rubles. On specially clever models not mentioned here because they are focused on the industrial user.
First of all, it is necessary to determine the functionality of the device and circuit. For their own needs are more suitable cleaver, hydraulic vertical type. Although they are less productive, but much smaller, and it is available for the manufacture of their own hands.
The next position is the selection of the type of drive. Use of a gasoline engine unit will give increased mobility, up to its application directly on the cutting portion. The electric drive is much more environmentally friendly and easier to pump and aggregation with the subsequent management, but is tied to the nearest electrical outlet. Should rely on the power of 220 W.
Finally, using conventional avtodomkrat can be manufactured improvised device which does not require an external drive. In this case, it logs, moving upwardly under force of the jack is split wedge or knife, which are fixed on the upper crosspiece of the rectangular frame. The jack is mounted on a T-shaped cross member that constitutes a bottom portion of the frame.
The working tool can be made in the following versions:
- Normal wedge (as shown in the figure), which includes a centering device for guiding a log exactly vertical axis intended cleavage. To this end, the logs need center bore axis, which once in the wedge will enter into the log more strictly perpendicular to its lower end. This will improve the quality of the cutting;
- The knife, which will immediately break down a piece of wood into two parts. The load thus increases as the tool contact area with the workpiece increase. At the same time, and will increase the quality of the cut surface that will get rid of the problems with loading solid fuel boilers;
- X-shaped knife which, when introduced into the wood at the same time fulfill its splitting into four pieces. It will also facilitate loading of the boiler, in addition, durability of the blade is greatest.
The jack may be adapted for producing horizontal gidrodrovokola. Adaptation in this case it is necessary to design a wheeled frame.
Hydraulic homemade splitter works. When the oscillating movements of the jack handle his rod comes into contact with the end of the log, and begins to work on him. The opposite end of the blank is stuck into the wood and splits it. By relieving pressure in the hydraulic jack installed on the left and right of the return springs return the rod to its original position.
When replacing the blade flat on the X-shaped firewood performance will increase double. If in this case the rate of firewood not satisfy the user. Have to equip cleaver pump installation. Here do without purchase in a shop of a suitable cylinder of the type (selection parameters previously described it), oil tank, pump-type or NS-32 NS-50, and the control valve.
For the manufacture of frames necessary to use a channel, and the actual installation mounted on a mobile cart.
