Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase productivity and reduce the required drive power. The device for cutting branches of trees and shrubs contains a cutting apparatus 1 with cutting 5 and contradictory 4 segments, knives 3 and mechanism 2 for eliminating low-quality cuts. The branches that have fallen into the mechanism 2 of poor quality cuts are rejected by the disks or interact with them, i.e., the branches are removed outside the cutting apparatus 1 or their full input. This is due to the rotation of the discs at the moment when the branches rest against the cutting apparatus due to their elasticity. 7 il.

Segments 5 () immobilize the kinematics of the reciprocating movement of the opposite segments 4 of the knife 3 and the oncoming oscillating movement of the cutting segments 5. Under counter relative displacements, the opposing segments 4 or the sleeves 16 lead the branches out of the device.

When a disc 1 or 12 contacts a branch to the right of the speed of the absolute change in the center of the disc 1 1 or 12, while moving segment 4 or 5 from left to right and to the left of the direction of the speed of the absolute displacement of the center of the disk 11 or 12, when moving segment 4 or 5 from right to left (zone Ii) arising respectively moments. or from the forces of resistance to bending of the branches on shoulder C or C7, overcoming moments from the friction forces M-rp.j of disk 11 on vt.pku 13 or Mrp.j disk 12 about sleeve 16, 1 (pi)) t 1isk 11 or 12 on sleeve 13 and. 1 and 16 and entered the branches of the cutting apparatus.

When a branch contacts a disk 11 or 12 at a point coinciding with the direction of the absolute speed of measuring the center of their axes of rotation, the branch at the beginning will be deflected by disk 1 or 12, while the variable direction of the absolute speed will not suffice (1 moment D. I overcome Momenga from SI;; p1i or zapgemit between 1 discs 11 and 12. When the branch between discs 11 and 12 is clasped (Fig. 7) against counter 1 about 4 p cutting 5 segments, discs 11 and 12 volts are driven to a branch in nanravle-leHHH of their absolute speeds of stirring. Like this, the common component of t forces late (i-twi disks 11 and 12 per branch will be greater than SI.1Y so | 11) and the bend of the branch and moments. and M, pj forces of friction: 1-. +; epi disk 11 vt.tku 13 and disk 12 on the ggulka I), disk 1 yuerputs, which will ensure 1a.1 throwing of vegvi into the cutting zone of the cutting 5 and protivorezhug, 1 4 segments.

Since the diameter of the discs 1 1 fixed on p)) from the left and right segments 4 is larger than the diameter of the discs 12 fixed on the cutting wheels 5, and the mounting of the axes of the joints 15 and 18 of the discs II and 12 on the backwash 4 and cutting 5 segments ensures their interaction cutting edges 19 and 20 across the entire length, the condition that 1 and 1 of them are in contact with the disks 11 and 12 at points coinciding with the direction of the absolute speeds of movement of their axes of the axes of connections 15 and 18, i.e. Ab. -ol the speeds of the centers of the axes of the axes 15 and 18 of the disks 11 and 12 prot., respectively, through the axes of rotation vlo 16 and 13, which eliminates the possibility) 1):, the expansion of the branches with the disks 11 and 12 without their selection from Mcxann.iMa psk.1yucheni poor-quality cuts with device breakage. Oi- labeled is very important when using the proposed mechanism for eliminating poor-quality cuts in segment-cutting devices with reciprocating, translational and circular relative movements of the cutting segments.

After the branch has been moved into the cutting unit, the cutting 4 and cutting 5 segments, having at the socks 14 and 17 ugach of pinching the cutting edges 19 and 20, ensure that the branch slides to the knife 3, thus eliminating the impact of the branch during its cutting on the disks II and 12.

The cut branches are moved along the knife 3 (Fig. 1) by the cutting segment 5 and fall from the back of the cutting apparatus, and subsequently laid by the workers between the tea bushes.
