Abstract

FIELD OF THE INVENTION The invention relates to agriculture and forestry. The purpose of the invention is to simplify the design. The device contains a vertical shaft, at the end of which a carrier element in the form of a disk 2 is mounted, and on the opposite end is placed a copier 3, made in the form of an oblique washer, the lower point of the working surface of which is located behind during the movement of the unit. On the disk 2, through the axis 4, the arms 5, spring-loaded with springs 6, are hinged. The cutting bodies 7 and the roller 8, which interact with the cam 3, 2 Il, are rigidly fixed on the arms 5. i SL

Description

The invention relates to tillage implements and can be used in agriculture and forestry.

The aim of the invention is to simplify the design of the cutter.

Fig. 1 shows a tillage cutter, side view; figure 2 is the same, top view.

The soil tillage cutter contains a vertical shaft (associated with the tractor's PTO (not shown). At one end of the shaft 1 there is a rigidly mounted carrier element, made in the form of a disk 2, and on the other there is a copier 3, made in the form of an oblique washer, the lower point of the working surface of which is located behind, in the direction of movement

unit. On disk 2 by means of a ball-2o working bodies, and at the expense of a umennira with an axis of 4, the radial is fixed; the levers 5, spring-loaded springs 6 relative to the disk 2. The axis 4 of the rotation of the levers 5 are located relative to the disk 2 tangentially. At one end of each lever 5 a cutting tool 7 is rigidly fixed, and on the other a roller 8 is placed with the possibility of free rotation around its axis, interacting with a cam 3.

Tillage cutter works as follows.

Before starting work, check the position of the copier 3, the lowered edge of which should be facing backwards.

When working from the tractor's PTO shaft, vertical 26 rotation is transmitted.

Invention Formula The tillage cutter comprising a body, a vertical rotary knot on which the radialio arms with knives are located and a copier for turning the levers, is fixed on the body, characterized in that, in order to simplify the design, the copier is made in the form of an oblique knob, and the levers are spring-loaded and axes their rotation is tangentially relative to the radial arrangement of the levers. 38793 Nomu wapa 1, which drives the disk 2 and the spring-loaded levers 5 fixed to it with cutting tools 7 and the rollers 8. When the disk 2 rotates, the rollers 8, touching the oblique plane of the copier 3, retract up and down the lever 5 with cutting tools 7, while ensuring the deviation of time 15 The barrel bodies 7 are back, and in the front part, the working bodies 7 with the cutting edge describe the circle and return it to its original position in the rear part of the circle. The application of the proposed device will provide increased reliability in operation by reducing the resistance The thickness of the chip to be removed will reduce the energy capacity of the unit.
