Mulching is a process of shredding logging residues into wood chips that remain on the land plot where branches and logging residues were mulched. The wood chips rot during the process, which has a beneficial effect on fertility. land plot. Today, mulching of logging residues is the most modern, cost-effective, environmentally friendly method of recycling logging residues. Removal of logging residues requires a lot of financial costs, including the collection and loading of logging residues as well as the cost of the bunker truck itself. The GreenProf company offers its clients the crushing of logging residues using special equipment.

According to a/c No. 979114, B27L 11/00, published on 12/07/1982, a mobile chipper is known, containing a self-propelled chassis on which a chopper, a hydraulic manipulator with a gripper, a fan, and a chopper drive are installed. The shredder includes a multi-cutting drum, a housing with a loading chuck, rotating device, consisting of a drive shaft and a belt drive. Levers are mounted on the drive shaft, which are moved along the lever and secured to it in a certain position. The operation of a mobile chipper is carried out as follows. Using a hydraulic manipulator using a gripping device, large-sized wood is fed into a loading chuck to a multi-cutter drum, which is used to chop the wood. To chop wood, a rotary device comes into play, which rotates the wood using a drive shaft and levers to a certain angle. By rotating the drive shaft in the opposite direction, the wood is pressed against the multi-cutter drum using levers. The resulting chips are carried by a fan through a chip pipeline to a chip truck.
According to patent No. 2354545, C1 B27L 11/00, published on May 10, 2009, (prototype) a device for grinding logging residues is known. It works as follows: by maneuvering the tractor, the device is moved to the pile of logging residues, so that the frame of the lifting device is located at the bottom of the pile of logging residues, using a hydraulic cylinder lifting device places the logging residues at the level of the larger equipment of the loading chuck body. Rotating cutting discs allow the cutting residues entering the loading chuck body to be given the desired dimensions, while the feeding device finger type, feed mechanism and feed rollers ensure a constant supply of branches into the loading cartridge body and further movement to the chopper. Crushed parts of crowns and branches are transported through a chip pipeline under the influence of centrifugal force.
Disadvantage of this device is that due to the low performance of the finger-type feeding device, the absence of gripping teeth on the feed rollers and a synchronizer on the pulleys, the productivity and quality of work on chopping logging residues is significantly reduced.
The technical objective of this invention is to increase the productivity and quality of the device for grinding logging residues.
The technical problem is solved in a device for grinding logging residues, containing a prismatic-shaped loading cartridge body, a chip pipeline, a chopper, a belt drive, a drive shaft, a feed mechanism, a lifting device frame, a hydraulic cylinder, a pipeline, an oil tank, cutting discs, a console, a system of pulleys with shafts , V-belt transmission, reduction gear, characterized in that the feed mechanism consists of a star-shaped feed device, the axis of which is installed at the base of the lower part of the inlet opening of the loading chuck, the feed rollers are equipped with gripping teeth perpendicularly attached to the inner side walls of the loading chuck body in two rows , and on the outer side of the side walls of the loading cartridge housing on the axis of the star-shaped feed device there is a synchronizer that ensures synchronous rotational movement of the units that are part of the feed mechanism.
The difference between the proposed invention and the prototype is that the feed mechanism consists of a star-shaped feed device, the axis of which is installed at the base of the lower part of the inlet opening of the loading chuck, and feed rollers equipped with gripping teeth perpendicularly attached to the inner side walls of the loading chuck body in two row, on the outer side of the side wall of the loading chuck body, on the axis of the star-shaped feeder, there is a synchronizer that ensures synchronous rotational movement of the components that make up the feed mechanism.
Figure 1 shows a side view of a device for grinding logging residues; Figure 2 shows a top view of a device for grinding logging residues.
The device for grinding logging residues contains a loading cartridge body 1, a chip pipeline 2, a chopper 3, a belt drive 4, a drive shaft 5, a feed mechanism 6 consisting of a star-shaped feeder, feed rollers 7 equipped with gripping teeth, a lifting device frame 8, a hydraulic cylinder 9, pipeline 10, oil tank 11, cutting discs 12, console 13, pulley system consisting of pulleys 14, pulley 15, pulley 16, shaft 17, shaft 18, V-belt drive 19, reduction gear 20 and synchronizer 21.
A device for crushing logging residues operates as follows: by maneuvering a tractor, the device is moved to a pile of logging residues in such a way that the frame of the lifting device 8, hinged on the outer side of the side walls of the housing of the loading cartridge 1 on the axis of the star-shaped feeder of the feed mechanism 6, is located at the bottom parts of a pile of logging residues. After this, in hydraulic cylinder 9 using pipeline 10 and oil tank 11 connected to the tractor hydraulic system, a overpressure. As a result, the hydraulic cylinder rod 9, coming out of the hydraulic cylinder body 9, acts on the frame of the lifting device 8. Since the frame of the lifting device 8 is a multi-link system, the horizontal movement of the hydraulic cylinder rod 9 is converted into the vertical movement of the frame of the lifting device 8. As a result, a pile of logging residues is located at the level of the larger base of the body of the loading cartridge 1, which has a prism-shaped shape, with the smaller base attached to the chopper 3, and the larger base is the inlet for supplying logging residues.
Rotating cutting disks 12, rigidly mounted by means of a console 13 on the axis of the star-shaped feeder of the feed mechanism 6, located on the sides of the entrance window of the loading cartridge housing 1, make it possible to give the cutting residues entering the loading cartridge housing 1 the required overall dimensions. In this case, the star-shaped feed device of the feed mechanism 6, the axis of which is installed at the base of the lower part of the inlet hole of the loading cartridge body 1, and the feed rollers 7, equipped with gripping teeth, perpendicularly attached to the inner side walls of the loading cartridge body 1 in two rows, provide constant feed branches into the body of the loading chuck 1 and further movement of the logging residues to the chopper 3. Synchronous rotational movement of the star-shaped feeding device of the feed mechanism 6 and the feed rollers 7, equipped with gripping teeth, and, accordingly, the linear movement of the crushed material in the body of the loading chuck 1 at a certain speed supply is ensured using a belt drive 4 and a pulley system consisting of pulleys 14 with a synchronizer 21, a pulley 15, a pulley 16, which are connected to the tractor power take-off shaft through a reduction gearbox 20 with shafts 17, 18 of the drive shaft 5 and a V-belt drive 19. The shape of the housing of the loading cartridge 1 and the feed rollers 7 located in it help to compact the mass of logging residues for grinding. Shredding of logging residues occurs with the help of cutting elements located on the front part of the chopper 3. The crushed parts of crowns and branches under the action of centrifugal force are transported through the wood chip pipe 2 into a receiving container or remain in the cutting area to rot.
Continuity of supply of material for grinding is ensured by moving the machine-tractor unit along the cutting area in low gear.
The design of the device for grinding logging residues allows to increase the productivity and quality of processing of logging residues in the clearing.

When felling and pruning trees, logging residues always remain. Be it sanitary cuttings or single removals, be it clearing swaths for construction or pruning dry branches. There will always be wood waste. Eat different ways getting rid of this type of waste.
1 Burning on site.
Quite quickly and inexpensively, but it is not always and everywhere permitted by law and is not always possible due to the increased fire hazard.
2 Removal and disposal.
Fast, but expensive. MSW (Domestic Solid Waste) bins with sizes from 8 to 27 cubic meters are ordered. The logging residues are loaded into them manually or mechanized and transported to the landfill for disposal. Everything is legal and always permitted.
3 Grinding of logging residues into chips.
Fast, economical and completely legal. With the help of a chopper, sawn wood is transformed into industrial chips with a fraction of 2-5 cm. Which can be used for gardening purposes or left at the cutting site, it will turn into fertilizer for the next season. You can also transport the wood chips in a bunker to the landfill if they are absolutely not needed. This is much more profitable than transporting uncut wood. Since unshredded wood residues take up 6-10 times more space (depending on the type of plant) than wood chips.
When we're talking about about the removal of 1-5 small trees, then there is not much difference in money, but when the volume of cutting is more than 10 trunks, the difference becomes very noticeable. And when exporting 100 or more units, it is colossal.
Let me show you clearly:
Let's say you have 4 trees that need to be removed.
The cost of supplying and removing 1 bunker for 27 cubic meters is about 10,000 rubles. Manual loading of a bunker costs about 5,500 rubles. One such bunker can accommodate about 4-5 trees with a diameter of 30 cm.
Means: loading + removal + disposal of 4-5 trees will cost 15,500 rubles.
Now imagine that you have 22 trees that need to be removed. The diameter is also up to 30 cm.
If we use the previous scheme, we find that we need 5 bunkers with loading, and this is 15,500 * 5 = 77,500 rubles. The amount is not small. Let's see how this amount changes if we use a chopper.
Calling a chopper costs 18,000 rubles (7 hour shift). Calling a bunker costs 10,000 rubles (most likely everything will fit in 1, it all depends on the type of tree, you may have to call another small bunker, 8 cubic meters, price about 4,000 rubles). Loaders will also be needed. For a day. 3 people – 9000 rubles. Total 18,000+10,000+9000 = 37,000 rubles (41,000 if you need to call a small bunker). The benefit is obvious. Almost 2 times.
Well, if you have more than a hundred trees, then it is calculated individually. Since such volumes are usually loaded mechanized. At large quantities Garbage collectors give discounts on ordered bins. But still, using a shredder will save from 50 to 70% of the removal budget.
During the period of planned cutting (sanitary felling) for landscaping and forestry management, public utilities, the global issue is the disposal of wood waste, the disposal of wood and logging residues, the processing of waste wood and woody vegetation. Our Center "Ecocenter" offers you a solution to this problem - chippers-shredders (loppers), crushers, wood waste crushers, wood chipper, limb chopper, wood crusher, branch crusher, waste crusher, chipper, chippers, wood chipper waste, with the help of which you obtain wood chips of various fractions for sale and improvement. With the help of this equipment, you will always be able to professionally and timely resolve issues: removal of old trees, removal of emergency trees, demolition of trees, demolition of emergency trees, felling of trees, cutting down trees, pruning of trees.Mulching solves the following problems of landscaping and landscaping:
At forestry enterprises, the issue of animal reproduction is acute; it is rational to use the resulting mulch to feed wild animals. Mulch can also be used as bedding for animals in domestic and livestock farms.
Older models of chippers will help solve the problem of disposal of sleepers. Powerful diesel engines, hydraulic supply of sleepers to the cutter and an excellent margin of safety and reliability make these grinders leaders in solving the problem of recycling sleepers at Russian Railways enterprises.
Some models of woodchip and branch cutter installations allow you to adjust the size of the woodchip fraction obtained after grinding the waste. The chips obtained in this way are an excellent raw material for receiving chipboard, which is then used in the production of furniture and is widely used in industry, as well as CBPB, which are used in construction.
More detailed information on the technology of using mulch in agricultural technology, as well as the technology for the production of decorative chips (dyed mulch), which is used for landscaping paths and children's playgrounds, can be sent upon request to our email: [email protected].
