(54) MACHINE FOR CLEANING FOREST CUTTINGS FROM SHEARED REMAINS AND KNOTS

one .

The invention relates to the forest industry and can be used for clearing cutting areas.

A known machine for clearing cuttings from stumps, wale and logging remnants, including a self-propelled chassis, on the frame of which there is an attachment in the form of a heap with a vertical stand and short teeth, and the blade is made composite along the length 1.

This machine has a low productivity, unsatisfactory quality of clearing. The rolls formed by the machine after its passage worsen the state of the environment, as in rolls from stumps, deadwood and forest residues there are pockets of diseases and forest pests that spread to forest cultures and adjacent forest tracts. The biomass is not used for recycling. For its subsequent use, additional labor and money are required for raking, loading and transporting biomass to storage and disposal sites.

A known machine for cleaning the cutting areas of logging residues and stumps, containing a self-propelled chassis, on a hydraulically controlled frame of which a working tooth is mounted, a working body, a hydraulic crane with a tooth having a maxillary grip 2.

The disadvantage of this machine is the low jioe quality of clearance of cuttings, high energy intensity. The machine cannot clear the flat strip in the cutting area due to the stumps that are often in its way. It skips the deadwood and logging residues,, Q pressed into the soil and overgrown with ground cover.

The purpose of the invention is to improve the quality of clearing cuttings from stumps, deadwood and logging residues and reducing energy intensity.

15 The goal is achieved by the fact that the teeth of one of the jaws of the grip are placed between the teeth of the working body, the latter being provided with a lock for fixing the teeth of the jaw grip, g frame provided with a supporting ski 23 connected to it.

FIG. 1 shows a car, a general view; in fig. 2 is a view A of FIG. one.

Claims (2)

The machine includes a self-propelled chassis 1, a hydraulically operated crane 2 with a 3-jaw gripper, a dump body 4, a frame 5 to which a bracket 6 is rigidly attached; The hydraulically-driven frame 7 is hinged to the lower part of the latter with a working body in the form of teeth 8, which are connected to the bracket 6 by means of a hydraulic cylinder 9, and a bar 10 between them. The bracket 6 and the frame 7 are connected by a hydraulic cylinder 11, the chrome frame 7 is hinged and by means of a hydraulic cylinder 12 with a supporting ski 13. The teeth 3 of one jaw of the grip can be positioned in the grooves between the teeth 8 of the working body in order to form a solid blade. A rigid connection of the teeth 3 and 8 is provided by a lock in the form of wedge lugs (not shown), the drive of which is supplied from the same pressure line and distributor as the drive of the maxillary grip with the teeth 3, made in the form of a hydraulic cylinder 14. The machine works as follows In this way, the driver of the self-propelled chassis 1 guides, with the aid of a hydraulically controlled crane, 2 teeth 3 of the maxillary grip into the grooves between the teeth 8 and with the help of the wedges firmly connects teeth 8 and 3. In this position, the teeth 8 and 3 form a blade. When the machine is moving, the driver of the chassis 1 using the hydraulic cylinder 12 adjusts the position of the teeth 8 relative to the soil surface and sets them so that the ends are located at ground level. In this position, the teeth 8 of the soil are not mineralized, which is a positive phenomenon when clearing cuts. Valezh and felling residues lying on the surface of the soil are scooped up and accumulated in front of the blade formed by teeth 8 and 3. Rowing is carried out until the collected biomass starts to prop up the other, free jaw of the grip, while the driver using a hydraulic cylinder 14 closes last. There is a pressing of the deadwood and felling residues on the machine dump. After pressing, the jaws are opened and the raking continues until the jaw grip is completely filled. When the maxillary grip is completely filled with forest residues, the driver, without stopping the chassis 1, closes the free jaw of the grip with the blade using the hydraulic crane 2 and the hydraulic cylinder 14, unlocks the wedge lugs and releases the closed jaw grip from the grooves of the teeth 8. Then the hydraulic crane 2 moves the jaw grip to feline and felling residues in the body of the chassis 1 and unloads wood junk. After the end of the unloading, the hydraulically operated crane 2 moves the clamshell to its original position. The clearing process continues. If on the road of movement of the machine there is a felling and logging residues pressed into the soil or overgrown with ground cover, the driver of chassis I sets the supporting ski 13 to a position where the zug 8 is below the level of the soil. In such a position of the writhing teeth 8, the pressed felling and logging residues are uprooted and raised to the heap. Then the clearing process continues with teeth 8 digged from the soil. When a stump is encountered in the path of the machine, the jaw grip is pulled out of the slots between the teeth 8 and in the closed state is transferred to the body 4 of the self-propelled chassis 1, unloaded and installed in the transport position in the back. Stump writhing by known methods of teeth 8 using traction force of chassis 1, hydraulic cylinder 9 and I. At the same time, to reduce the load on the self-propelled chassis 1, support skis 13 are put into operation with the help of hydraulic cylinder 12. The uprooted stump with maxillary grip is loaded into body 4. Further machine operation continues in one of the three modes described. When the body 4 is filled, the working body is moved to the transport position, and the chassis is sent to the place of unloading of the body 4 and storing the biomass of wood junk. Thus, the proposed machine allows to improve the quality of clearing cuttings by removing stumps, deadwood and logging residues located on the soil surface and pressed and overgrown with ground cover at lower energy costs. Claims The machine for cleaning the cutting areas of logging residues and stumps, containing a self-propelled chassis, on a hydraulically controlled frame of which a working tooth has been mounted, a hydraulic crane with a tooth having a maxillary grip, characterized in that, in order to improve the quality of cleaning and reduce energy intensity, the tooth one jaw grip is placed between the teeth of the working body, the latter is provided with a lock for fixing the teeth of the jaw grip, and the frame is provided with a supporting ski connected to it by means of a hydraulic cylinder.
