Description

Mounted 1Shaws1Other guns with rotary working bodies, cutters, are known. Their disadvantage is the complex structure of non-transmission of movement to the working bodies and the need to install additional passive working bodies such as tiller legs for the destruction of blemishes between sections.

In the proposed device, this disadvantage is eliminated. This is achieved by arranging the sections of the working bodies in such a way that the distance between the inner edges of the sections is equal to or slightly less than the width of the gripping sections and the distance between the inner edges of the wheels OR of the tracks of the tractor. This arrangement allows us to apply a new, technological scheme of tillage without installing additional working bodies and to place the drive of working bodies in the middle of the drum cutter shaft, while simplifying its design.

FIG. 1 shows a diagram of the device and the treatment of the floor, when mounted on a wheeled tractor; in fig. 2 - the same. when mounted on a tracked tractor.

The device consists of a frame cutter /, hung on a three-point on the hydraulic 2 tractor 3. The shaft 4 is mounted on the frame, carrying two sections 5 of the milling working bodies.

In the middle part of the shaft between the sections of the working bodies, a tri-water box 6 with a pair of bevel gears 7 is installed, receiving rotation from the shaft 8 of the tractor's power output. The distance between the sections is assumed to be equal to the width of one section or a little (5-10 cm less. At the same time the distance between the inner edges of the sections is less than or equal to the distance between the inner sides of the wheels OR tracks of the tractor.

This arrangement of the sections of the working bodies allowed to simplify the design of the gearbox and apply a new technological processing scheme. During the first pass of the unit, the working bodies of the cutter process two strips of soil, leaving untreated STRIPS between them, a little narrower in width than the width of the treated STRIPs. During the backward passage of the unit, the grader goes with one caterpillar or wheels along the untreated strip, and treats it with one out of the cutter sections. This method of processing eliminates the need to install additional passive working bodies on the mill for processing the space between sections and further simplifies the overall design of the device.

Predmemt and z obreteni

A soil tillage cutter, trailed or mounted, with forced rotation of the working bodies, including two sections and a drive device, characterized in that, in order to simplify the design of the drive device and the whole tool, the sections of the working bodies are located symmetrically relative to the axis of the unit , the distance between the inner edges of the sections being equally small, slightly less than the size of one section and the distance between the inner edges of the wheels or tracks of the tractor.
