Abstract

The invention relates to mechanical engineering and can be used to perform unloading operations, in particular, for unloading of hard-flowing materials with bulk delivery in covered wagons. The purpose of the invention is to increase efficiency by providing loosening of the load. The device consists of two levers installed on the base for movement in the vertical and horizontal planes and pivotally in the horizontal plane, each of which has cranks 3, which are rotatable by drive, that carry cantilever scraper conveyors 4 with combs 8, which are mounted on the sides of the conveyors. During operation, the conveyors make plane-parallel circular movements to loosen the load. 2 hp ff, 5 ill.

Description

FIG I

The invention relates to mechanical engineering and can be used for unloading operations, in particular for unloading of hard-flowing materials with bulk delivery in covered wagons.

The purpose of the invention is to increase efficiency by providing loosening of the load.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, top view, section; in FIG. 3, view A in FIG. 2; in fig. 4 shows the device folded; FIG. 5 - input device diagram.

The device for unloading bulk cargo from covered wagons contains an arrow mounted on the base with the possibility of movement in the vertical and transverse horizontal planes, on which two levers 1 are pivotally mounted with the possibility of rotation in the vertical plane, each of which is equipped with sprockets 2, with which cranks 3 are associated. The cranks have a scraper conveyor 4 connected to the cranks with the brackets 5 with the drive sprocket 6. The chains of the conveyors 4 are equipped with the scrapers 7. A comb 8 is installed on the sides of each conveyor, in one of which, the second along the movement, a notch 9 is made, the length of which is equal to twice the length of the crank.

The device works as follows.

The device is inserted into the upper part of the car in a folded form through the doorway, gradually opening up with the drive action of the PFD. After the levers are fully turned, the conveyor 4 is set in motion in the horizontal plane with the help of cranks 3, interconnected by a chain transmission, simultaneously coaepiilaH rotating

body movement, the cargo is scraped out by scrapers 7 and combs 8.

The opened arms 1 gradually lower as the car leaves, and when they are fully depleted, the device gradually assumes its original position for removal from the car.

When the conveyor rotates on cranks in the zone of the crank closest to the doorway, the material level is higher. To prevent this material from moving with a comb to the end of the car, a notch 9 is made in the combs.

Claims (3)

1. A device for unloading bulk cargo from covered wagons, comprising a boom mounted on the base for moving vertically and across the car in the horizontal planes, on which at least two levers are pivotally mounted to rotate in the horizontal plane of which is associated with a corresponding conveyor, characterized in that, in order to increase efficiency by ensuring loosening of the load, it is equipped with two cranks mounted on each arm so that it can rotate in a horizontal plane carrying the said conveyor. 2. The device according to claim 1, that is, that each conveyor is complete with a cantilever section. 3. The device according to paragraphs. 1 and 2, characterized in that it is provided with vertical combs rigidly fixed on the sides of each conveyor, in the lower part of one of which a cut is made, the length of which is equal to twice the length of the crank. 8ud / f eight fig.b FIG. . 5
