Description

(54) BRUSH CUT

The invention relates to machines for cutting the above-ground part of unwanted tree and shrub vegetation in caring for forest crops in cuttings and so forth and clearing the area from bushes and can be used in forestry.

Known brush cutter, including a self-propelled chassis, on which is installed a frame with an active working body in the form of a cylindrical cutter, which is located at an angle to the longitudinal axis of the brush cutter and zashish, en on the feed side of the visor, mounted on the platform 1.

The brush cutter is also known; the AI cylindrical cylindrical milling cutter mounted on the self-propelled chassis frame, a hydraulic actuator and a device for receiving and directing cut vegetation 2.

The disadvantage of these brush cutters is that their working equipment does not ensure the normal operation of the brush cutters, due to the frequent clogging of cut material and forced stops.

for CLEANING.

The purpose of the invention is to improve the quality of work by eliminating the clogging of working equipment of cut vegetation.

The goal is achieved by the fact that the frame is weakened by a reflector shield and is made with a rectangular through opening, which is limited in front by a cylindrical cutter, and, from the sides, by the guides of the spacer and by the reflector shield.

FIG. 1 shows a brush cutter, side view; in fig. 2 - the same, top view.

The brush cutter consists of a self-propelled chassis /, in front of which a frame 3 controlled by hydraulic cylinders 2 is installed. The frame is equipped with a knife cylindrical cutter 4, guide stoppers 5 and shield guard 6, which together form a device for receiving the "direction under the tractor of cut trees and shrubs." The guide bridges 1 and 5 are rigidly fixed on the longitudinal bars of the frame 3, and the reflector shield 6 is fixed on the cross bar of the frame by means of a hinge 7 and a hydrocylide 8.

Cutter 4 is driven by hydromotors & . by means of gearbox W and V-belts, 11. Hydraulic equipment, including tank, pumping station, oil lines. And distributor, on

f, ilg not shown.

The construction of the brush cutter forms in the frame 3 a through lroy 12.

For the operation of the cutter frame 3 by means of the hydraulic cylinder 2 is lowered so that the through opening {12, bounded by the knife cutter 4, using the limiter 5 and the reflector shield 6, is inclined downward along the cutter, and the reflector shield 6 is hydrocyl nidrome 8 is mounted vertically.

An idromotor and 9 knives cylindrical milling cutter 4 is rotated in a direction opposite to the stroke of the brush cutter. During the movement of the brush cutter, on its way, the growth of woody n shrub vegetation is cut by knives MILLING 4 and thrown up and back so that the butt part of the cut trunks falls into the through opening 12 of the device for receiving and directing the cut material under the tractor and, having passed it falls to the ground.

The upper part of the trunks at this time interacts with the guiding limiters 5 and the reflector shield 6. The guiding stops 5 keep the trunks of cut vegetation from flashing and falling to the side, and the reflector shield 6 takes the crowns of the cut plants iH as a result of the forward movement of the brush cutter, he pushes them forward, stepping down the stem and filling their knife cutter 4. The cutter blades 4 at this time cut off the branches of the branches located on the Bottom side 1 and push tvoliki under the tractor. As a result, cut vegetation is laid on the ground, tops forward along the brush cutter, and due to trimming of the lower branches, it is well attached to the ground. This is very positive, as it is tightly laid on the ground.

vegetation rotting much faster.

The transfer of the brush cutter to the transport position is carried out by raising the frame 3 with the hydraulic cylinders 2 and lowering the reflector shield 6 with its laying on the frame 3 with the hydraulic cylinder i8.

The proposed brush cutter does not clog with the cut material, does not require stops for cleaning the working body and, in comparison with the known ones, has higher quality and productivity.

By increasing productivity

The brush cutter provides an economical effect for the national household, as this

leads to a decrease in labor and cash

costs per unit of volatile work.
