(54) THE WORKING BODY OF THE DREAMER

one

The invention relates to machines for the development of frozen and durable soils, namely, rippers.

Known mounted ripper for preparing the soil for development, including tips, mounted on the poles of the ripper, vertical dumps with a cavity, which are mounted on the drains using hinges. The hollow dump is provided with outlets located along the entire height of the blade on its side walls. The hollow heap has an inlet. When the mounted ripper moves with the tips buried in the ground, the liquid flows through the nozzle into the cavity of the rotary blade and is sprayed through the outlet holes onto the walls of the loosening furrow over its entire depth, preventing the destroyed ground from freezing 1.

The closest technical solution to the proposed is a working body of the ripper, including the back tooth with a stand and the front tooth 2 above it.

The disadvantage of this working body of the ripper is the considerable effort required to loosen durable and frozen soils, due to the difficult exit, of the soil destroyed by the back tooth (this is prevented by the front tooth of the ripper) and even its jamming.

The purpose of the invention is to reduce the energy intensity of the loosening process.

The goal is achieved by the fact that the working organ of the х х eater is equipped with an additional stand on which the front tooth is mounted, with both stands made with versatile directional longitudinal bends. The bending lines of the struts are located from the cutting edges of the respective teeth at a distance determined from the ratios

H, 0, Hg 0.75H, 15 where H1 and H2 are the distances from the cutting edges of the front and rear teeth, respectively, to the bending line of the posts on which they are made; mm;

Ngpah - maximum loosening depth of the working body, mm.

FIG. 1 shows the working body of the ripper, a general view; in fig. 2 - the same, side view; in fig. 3 - the same, front view.

The working body of the ripper consists of two racks — front 1 and rear 2, respectively, with loosening teeth — front 3 and rear 4. The ripper 1 and 2 are mounted one behind the other, and their loosening teeth 3 and 4 are located at different levels — front the loosening tooth 3 is higher than the posterior loosening tooth 4. There is a semicircular window 5 between the front 1 and rear 2 racks, and bends b and 7 are made on the lateral surfaces of the racks 1 and 2, respectively, in opposite directions. At the front of the rack 1 there are mounting holes 8. The working tool of the ripper is mounted on a crawler tractor (not shown).

In addition, the bends on the posts relative to the lower cutting edges of the teeth are made at levels determined by the ratio of the parameters:

H, 0.5Nta; Н2 0.75Н „ah. where HI is the height of the position of the front bend relative to the cutting edge of the front loose tooth;

H2 is the height of the posterior bend relative to the cutting edge of the posterior loosening tooth;

Ntpah - maximum depth loosening of the working body as a whole.

The working body of the ripper works as follows.

When the tractor is moving, the working body is buried in the soil mass. Initially, the front loosening tooth 3 interacts with the developed medium, as a result of which the destroyed medium (soil) rises along stand 1 and, due to the presence of bend 6, moves in one direction, located parallel to the furrow made by the working body (similar to the agricultural plow). In this case, the depth of loosening by the front tooth 3 is half the total depth of loosening by the working body as a whole. Therefore, the implementation of the bend 6 on the front of the rack 1 is advisable at the same level, i.e. Ht. performed by the working body on the other side. In this case, the bend 7 is performed at the N2 level, determined by the ratio, 75 N the axial ratio is determined by the fact that the posterior loosening tooth 4 also develops half of the total loosening depth (0.5 Ntah) but since partial hit

the broken ground in the furrow made by the tooth 3, then the bend 7 on the rear pillar 2 is made above that level by half the depth of loosening by the front tooth 3, i.e. on 0,25khNpi. Therefore rational

The height HZ of the location of the bend 7 of the total depth of the loosening H mta is determined by the ratio H2 (0.5 +0.25) hNtah 0.75Ntah. On the base tractor, the working tool of the ripper is installed using mounting holes 8.

Thus, the implementation of the proposed working body of the ripper with two racks, and bends on their side surfaces, ensures reliable, highly efficient operation of the working body, eliminates jamming of the space (semicircular window) between the racks, and reduces the energy intensity of the loosening process.
