(54) WORK BODY OF THE DIGGER MACHINE

one

The invention relates to the construction and can be used in the construction of lines of closed drainage.

According to the main author. St. No. 815167 is known for the working body of the earthmoving machine, including cutting racks spaced apart in width and connected in the lower part to the undercutting section, and in the upper part displaced in the direction of motion and connected by spacers and a ground reflector, while the racks are displaced one relative to another throughout the depth of cut. in the direction of movement at a distance not less than the width of the front cutting column, and the cutting section and the reflector are made of a constant width equal to the distance between the legs and are attached to the rear cutting column 1.

A disadvantage of the known technical solution is the low quality of the slit drainage, since even in moist soils often the slit remains uncovered from above.

The aim of the invention is to improve the quality of the slotted drain by providing the possibility of accompanying the cutting of the cover of the drain on top of the sod strip.

The goal is achieved by the fact that the working body of the earthmoving machine is equipped with a turf sub-rigger located in the zone of the upper part of the cutting columns and the ground reflector and attached to them.

At the same time, the sod-pruner-arcuator is made in the form of a cutting pillars located ahead of it and having a width greater than the width of their spacing, a one-sided back-off plow body for

10 trimming and temporary elastic limb in the direction of the strip of turf and adjoining the back of the body of the longitudinal shield located on the bend side of the strip of turf, to keep it in the bent position before the passage of the slant forming agent and to prevent the ground from being fed by the reflector under the bent strip.

FIG. 1 shows a working body, side view; in fig. 2 is a kinogram of slit drain formation.

The working body of the earthmoving machine includes cutting racks 1, placed in width and connected in the lower part with the undercutting section 2, and in the upper part displaced in the direction of movement and connected by spacers 3 with the reflector 4 of the soil, while the racks are displaced one relative to another throughout the depth cutting in the direction of movement over a distance not less than the width of the front cutting column, and the undercutting section 2 and the reflector 4 are made of a constant width equal to the distance between the columns in the lower part and are attached to the rear cutting edge kyo. The working body is equipped with a turf cutter water generator, which is located in the zone of the upper part of the cutting racks 1 and the reflector 4 of the soil and attached to them. The specified additional working body is made in the form of the A-Racks located in front and having a width greater than the width of their spacing, a one-sided bottomless plow body 5 and behind the longitudinal shield 6 adjacent to it, located on the bend side of the turf strip 7.

The working body of the earthmoving machine works as follows.

When the working tool is pulled, a layer of turf is cut sequentially with a cutting knife 8 of a one-sided off-ground plow body 5 (Fig. 2a), trimming and elastic limb in the direction of the turf strip 7 by the ploughshare 9 of this body (Fig. 26) 1 (Fig. 2c), the rise of the soil

from the drain 10 by the reflector 4 with the exception of soil penetration under the bent strip 7 of the turf, which is facilitated by the presence of the longitudinal shield 6 (Fig. 2d), lowering the bent strip 7 of the turf to its original position (Fig. 2e). As a result, the slit drain 10 is covered from above.
