SU990142A1 - Bush cutter rotor - Google Patents

Description

The invention relates to rotary type brush cutters and can be used in agriculture and forestry for cutting and shredding shrubs and other agricultural crops.

Known rotor brush cutter, containing. Shaft with eccentric axes, on which s; c1 attached working bodies with cutting elements C 3

The known rotor does not fix the stalks of the bush at the time of their cutting. This entails poor-quality cut and shredding of shrub material, and as a result,. weight loss, and reduced brush cutter performance, higher energy intensity.

In addition, the known design of the rotor of the brush cutter is very effective in cutting a piece of wood-based material with a diameter of over 60 mm.

The purpose of the invention is to improve the quality of the cut and shredding shrubs. .

 This goal is achieved by the fact that the rotor is equipped with discs with a tooth and a plate that guards them with slots for the teeth of the discs; than working bodies located between

disks, at the same time, disks have the dihydate, bigger diameter of a trajectory of the ends; working bodies by an amount equal to two distances between adjacent disks, and the angle of the teeth is O.

FIG. 1 shows a rotor of a brush cutter; a general view; FIG. 2, - cut

10A-A in FIG. i; in fig. 3 is a scheme for cutting wood material with a disk cutter.

The brush cutter rotor is a set of discs 1 interconnected between

15 by themselves into one i whole with eccentric axes 2, on which the working bodies 3 are hinged. The 1fine disks 4 are rigidly connected to the semiaxes 5, which are installed in the supporting sub20 of the brush cutter frame b (not shown). On the frame 6 of the brush cutter there are located an anti-cutting plate 7 with cut-outs for the passage between them of the disks 1 with teeth 8 and the deflector 9 for placing 25 ground chopped wood pulp in transport means. Working bodies 3 are made with a curved surface to allow directional transportation of crushed

30% of the mass in vehicles

The rotor brush cutter works as follows.

When the rotor rotates, the working bodies 3 occupy the initial radial position under the action of centrifugal forces. When the brush cutter moves across the field, the bushes, between the rotating disks 1, are fixed in a vertical position with the side surfaces of the disks 1, cut, they are crushed by the working bodies 3 when interacting with the counter shear plate and transported along the deflector 9 into the container. Fixing :-( Stubble of a bush between disks 1 is possible due to the fact that the diameter of the trajectory of movement of the ends of the working bodies 3 is smaller than the diameter of disks 1 by values equal to twice the distance between disks 1 and cutting the shrub stalks between the disks 1, the latter are cutting side branches shrub stalks, contributing to more efficient cutting and shredding shrub sprouting.When meeting with the stalks / shrub diameter greater than the distance between the discs 1, the latter due to the presence the teeth 8 cut into these | stems and cut the shrub stalks into pieces that, between jyicles 1, are cut and crushed by the working bodies 3. Due to the fact that the lateral cutting edges of the teeth 8 of the discs 1 are parallel to the planes passing through the midpoints of the opposite depressions disks 1,

it provides a cutting angle equal to O. .

The proposed device makes it possible to improve the quality of the cut. - and shredding trees and shrubs, and agricultural crops, and to increase the productivity of the brush cutter.

Claims (3)

1. A brush cutter rotor containing a shaft with eccentric axes on which working bodies with cutting elements are hinged, characterized in that, in order to increase the quality of cutting and shredding of the shrub, the rotor is equipped with tooth disks and counter-holding for (THIS plate with slots for the teeth of the discs, with the working bodies located between the discs. 2. A rotor according to claim 1, characterized in that the disks have a diameter of i-meter that is larger than the trajectory diameter of the working member bodies by an amount equal to two distances between adjacent disks. 3. The rotor according to claim 1, about tl and h ayush and the fact that the angle of the teeth is equal to O. Sources of information taken into account during the examination 1.
