Abstract

The invention relates to earthmoving equipment and can be used to extract pits for covering equipment. The goal is to reduce the energy intensity of the digging process by reducing the number of passes. The working body of the excavated machine includes an inclined rotor with cutting elements (OM) 9 and a plow working body with a cutting knife. The inclined rotor is made in the form of a face ring 6 with a toothed drive ring 7 fixed on it. On the outer surface of the ring 6, the OM is installed so that two ER 9 out of three overlap the width of the ring 6 and the third protrudes inside the ring 6 by half its width. The cutting knife of the plow tool has an arcuate shape in the middle part, and its extreme sections are made straight and have a width equal to at least the width of the track. The angle of inclination of the rotor 6, when buried in the ground, is 30 ° C, which provides an elliptical profile excavation profile. The soil is developed by the ER 9 for a width sufficient to allow the rotor to move freely. Plow tool body profiles horizontal platforms under the tracks. As the machine moves to the bottom, the pillars of the soil are squeezed onto the elevating conveyor and are thrown in the direction of the excavation. 3 il. i (L with 4 and with Figure 2

The invention relates to earthmoving machinery and can be used for fragments of a pit excavator.

technology.

The aim of the invention is to reduce the energy consumption of the digging process by reducing the number of passes.

FIG. I depicts the working body in the process of work, a general view; in fig. 2 — node 1 in FIG. one; in fig. 3- profile excavation pit.

On the base machine 1, the U-shaped pushing frame 2 is mounted on the supports so that the holder 3 of the inclined rotor 4 is rigidly attached to the cross beam at an angle of 30 to the frame plane. The holder is attached in the lower part to the plow tool 5 that performs soil picker function. Naklorgny rotor 4 is mounted on bearings, has a T-shaped cross-section and is made in the form of an end ring 6 with a gear drive rim 7 fixed on it, by means of which the rotation of an inclined rotor is transmitted through a gearbox 8. On the outer surface of the rotor ring 6, cutting elements 9 are installed so that, of the three, two cutting elements overlap the width of the ring, and the third protrudes into the ring half the width of the ring.

The working body 5 is made of a welded box-shaped structure in the form of a wedge, fastened with sidewalls to a heavy frame. There are cutting knives on the sidewalls and the leading edge of the plow tool, the extreme right molar to form the pads 10 under the tracks of the base machine, and the middle part of the cutting knife is arcuate and curved so that it copies the ellipse notch 11.

The belt-type elevating conveyor is made of two parts: the lower 12 and the upper 13. The lower part of the elevating conveyor has the ability to rotate together with the pushing frame when the working member is moved to the transport position. The upper part of the lifting conveyor is fixed obliquely on the platform of the machine so that

The dispensing end is located under the discharge conveyor 14. The discharge conveyor is mounted on the platform across the machine. The receiving part of the unloading conveyor covers the entire bus.

The elevator is designed and the outstanding part stands for the 1st car of the base machine at I, 5–2 m for the ejection of the soil in such a way that the soil does not fall into the excavation. To transfer the working body to the transport position, two hydraulic cylinders 15 are installed on the sides of the platform. The hydraulic cylinders' rods are connected to the brackets, which are fixed to the pushing frame.

Pit machine works as follows.

The base machine, when moved backwards with the help of hydraulic cylinders, digs into the ground a rotating ring rotor. The depth of the rotor stops as soon as the depth of the recess is 1 m, and the angle of inclination of the rotor to the horizontal plane will be 30 °, and the transverse stick does not touch the surface of the ground. With this inclination of the rotor, the profile of the notch is elliptical. The rotor tooth develops a strip of soil a width sufficient for free movement in the development of the annular rotor.

The movement is right behind the rotor, the pickup forms horizontal platforms under the tracks of the base machine and takes up the rear of the ground, resulting from cutting the soil mass with the ring rotor. As the machine moves to the bottom, the pillars of the soil are squeezed out from the pick-up onto the elevator conveyor and further upwards. The speed of the lifting conveyor is set so that the horizontal component of the speed of the conveyor is equal and opposite to the speed of the machine on the bottom, while the ground relative to the earth moves vertically upwards. From the lifting conveyor, the ground pillar (ground) falls on the receiving part of the unloading conveyor and is thrown away from the trench.
