Description

one

The invention relates to earthmoving machinery, in particular, to machines with a chain working body for digging trenches and trenches.

The purpose of the invention is the expansion of technological capabilities by ensuring the development of pits in frozen soils by passing milling.

FIG. G is represented by a digging machine, side view; figure 2 is the same, the view in the plan.

The earthmoving machine contains mt 1, a frame 2 with a thrower 3 and a working body 4 mounted with the possibility of oscillating movement in a horizontal plane by means of hydraulic cylinders 5. Under the working body in the direction of ground movement into the thrower by means of a tg fixed by fingers 6, pshkk soil. The pick-up is made in the form of a stripping knife 7, which is connected by a chute S to a receiving tray 9 of the throwers. The amplitude of the rolling blade of the trimming knife Hz is greater than the external dimensions of t gacha along the width Lg.

In the contact area of the pick-up with the receiving tray of the scooper, a limit switch is installed, connected to the control system of the hydraulic cylinders 10 for lowering the working member. When the switch is triggered, the hydraulic cylinders of the lowering of the working member and the latter are automatically disconnected

It is forced to the initial position for the development of pits in frozen ground.

The machine works as follows.

When developing ditches in frozen ground, a working body (previously transferred to the initial position), along with the movement of the chain and swing in the horizontal plane, translate in the direction of passing milling is reported (the loading tool gives the working body to

15 asshole back). The orientation of the working body in relation to the face. (depth or depth) is provided by turning it with the frame (as a rigid system) around

20 Horizontal hinge on a t-pitch by means of hydraulic cylinders 11, In the steady state, the development of an array of frozen ground is carried out only by the cutters, bending around

25 asterisk. The developed soil is captured by a pick-up knife and transported along the chute with the blades of the working tool chain to the thrower, which feeds it to the dump. Thanks to that

30 that the amplitude of contact of the sweep knife is larger than the external dimensions of the gacha in width, the machine can freely move along the bottom of the slab in the feed direction.
