Description

MACHINE FOR PRODUCTION OF EARTH WORKS

It was filed on December 22, 1944 in the People's Commissariat for the number 796 (335791) Published September 30, 1946

The invention relates to machines for the production of earthworks, in which an elevator with a working plow body in front of it is used.

Distinctive feature

The proposed machine is that the plow is made up of two bodies mounted at an angle to each other, the knives of which at the rear end converge with each other, and between the dumps there is a free passage through which the cut-off knives over the entire width of the plow is fed to the central located elevator.

The proposed machine is intended for land works, in particular:

a) to clean the irrigation canals from sediment and build new canals;

b) for the construction of embankments from the side reserves.

In FIG. 1 shows the plan of the machine; FIG. 2 is a view along arrow // in FIG. one; FIG. 3 is a view along arrow /// in FIG. 2

The machine has two engines. One of these engines serves to drive the movement.

traversing and overcoming the plow resistance, as well as driving the lifting devices. The second engine serves to drive the bucket drum and the conveyors of the main and feeder.

The main frame of the machine is metal, welded serves as a core for the installation and fastening on it all the mechanisms and parts.

A plow / for cutting soil consists of two bodies located in front of the machine at an angle to each other. Each housing consists of a knife 3, a blade 4, and a rack, sludge ash; at the same time it also has a fifth plow body. The rear ends of the blade and the legs are interconnected by a beam to give the HvecTKOCTH housing. The plow body knives almost coincide with one another. The inner sides of the heaps are trimmed to form a passage for the ground cut by knives to elevator 2; the distance between the dumps in the rear end of them is equal to the width of the buckets of the bucket elevator 2.

The plow bodies in the front of their racks are hingedly suspended by two longitudinal

channels 5, which are connected by a transverse channel and serve as a frame for the plow. The rear ends of the longitudinal channels 5 are hinged on axle x 6 mounted on the main frame 7 of the machine. To change the cutting angle when changing the depth of penetration, the rear ends of the plow bodies are suspended with help and vertical bars to the transverse channel of the frame. For adjustment, holes are drilled into these bars where the pins are inserted. The plow with its frame is suspended on a rope 8. The plow is switched on to work and is lifted to the transport position with the help of a winch. In the transport position, the plow can be raised to a height of 1.5 m from the ground. The depth of the plowing plow reaches 200 mm. Capture width 2500 mm.

The bucket elevator 2 serves to scoop and lift the cut and loosened soil with a plow and transfer it to the conveyor 9.

. The bucket elevator consists of two gear rims 10, interconnected by transverse struts. To the rims on bolts fastenings buckets //.

Elevator buckets scoop only the soil loosened by the plow. Unloading buckets from the soil to the conveyor is

by means of swiveling bottoms, hinged on the axles of the scoops. Rotation of the bottoms occurs when they run onto the roller installed at the conveyor 9. Thanks to the forced unloading, the machine works on wet and sticky soils.

In order for the soil cut by the plow not to flow out to the sides and sent to the buckets of the bucket elevator, special ground guides, G2 cheeks, are installed on the latter, with their front ends slightly going over the plow heaps. In order not to create excessive resistance, the lower edges of the cheeks 12 do not reach the ground at a distance of 10-20 mm.

Subject invention

A land works machine using an elevator and having a working plow body in front of it, meaning that the latter is made up of two bodies mounted at an angle to each other, the knives 3 of which at the rear end converge with each other, and Between the dumps 4 there is a free passage through which the soil cut by knives across the entire width of the plow is fed to the centrally located elevator 2.
