SU883235A1 - Working member of mole-type drain-driving machine - Google Patents

Description

one

The invention relates to ameliorative technique and is intended for laying mole drains in soils.

Known working body of the Krotodre-. Ngiknoy machine, including a knife with a drainem, consisting of a body and a conical tip l.

A disadvantage of the known device is that it does not provide for the dynesthetic consolidation of the walls of mole drains.

Another working body of the crooker is also known, which includes a knife and a draining machine attached to it with a spike tip, in the hollow chamber of which a magnetostrictive vibrator 2 is attached to the front end wall.

A disadvantage of the known device is that the vibrator has a high frequency, but a small amplitude, which does not effectively condense the walls of the crotto, as there is an elastic deflection of the soil, and not plastic.

The purpose of the invention is to increase the efficiency of compaction of the walls of drains.

This goal is achieved by the fact that the working body is provided with a percussion device located in the body of the drainera, interacting with a conical tip, which i is installed in the body with the possibility of axial movement relative to the latter.

FIG. 1 shows a crotodrain machine, general view; in fig. 2 is a schematic diagram of the working body of the drainage machine.

ten

The crotodrain machine includes a base hydraulic pump 1 with a volumetric hydraulic drive, a linkage mechanism and a working body 2 (Fig. 1). The hinge is made parallelogram, zg1mykayuschim

15, the link of which is the slide 3 with a curved guide groove 4. The frame of the working element 5 is connected with the slide 3 by means of rollers 6. Installed between the frame 5 of the working member

20 of the body and the link 3, the elastic elements (springs) 7 do not allow the working body to be arbitrarily deepened and deepened. The hydraulic cylinder 8 serves to transfer the working device to the transport position and to regulate the depth of the laying of the crotodrain.

The working body 2 consists of a knife 9, a body 10 of a drainera, a piston-block 11 with a built-in {lm in it control unit consisting of a sleeve 12 and a spool 13 of control and a movable cone tip 14 with a shank 15. openings and axial channels connecting the charging cavity 8 with the drain cavity C at the leftmost position of the control valve spool 13. The cavity 15, formed by the piston of the non-brisk 11 and the housing 10, is filled with gas under the initial pressure and is a pneumoaccumulator. The knife 9 has pipelines for the supply of liquid through the longitudinal windows in the casing 10 to the charging and discharge lines. Krotodrainage machine works as follows. As it moves forward, the hammer blows to the hydrodynamic hammer strikes the corporeal movable tip forking the mezzanine. The speed of the base machine, the frequency of strikes of the striker, and the amount of movement of the tip correspond to the ratio V,} if-TL HVL where V is the frequency of impacts per unit of time; Vg - j-- speed of base t gacha; X-U is the amount of movement of the tip in one stroke. This ensures the dynamic formation of the crocodile. When striking a movable conical tip, the impurity is inserted into the ground for the amount of displacement. During the cocking of a hydropneumatic hammer, the metodrainage machine moves an amount equal to or slightly smaller than the movement of the tip and presses the hammer body against it. At this time, the next strike is made. This eliminates the static formation of the drain. The presence of a movable cone-shaped tool in a draining machine ensures effective compaction of the walls of the crotodren due to plastic deformation of the soil and reduces traction resistance to the introduction of the working body into the soil. Powering the hydropneumatic hammer from the hydraulic system of the base gauge simplifies the drive of the worker, eliminating the need to install additional equipment on the basic gauge of the gauge. Theoretical studies show that the amount of irrigation by molehills arranged by the proposed working body is greater than that by the molehills produced by the vibrating working body. Claims The working body of a drip machine, comprising a knife with a draining machine consisting of a body and a cone tip, characterized in that, in order to increase the efficiency of sealing the walls of the drains, the working body is provided with a percussion device in the body of the draining machine that interacts with the conical tip, which installed in the housing with the possibility of axial movement relative to the latter.
