ABOUT)

The invention relates to the mining industry, in particular to trolleys for transporting rock mass.

The purpose of the invention is to increase the efficiency of cleaning the cuvea from the adhering and frozen material.

Figure 1 shows the trolley, a general view; 2 - two chain links at the sides of the trolley, {| cut).

At the bottom 1 of the trolley 2, a grid 3 is placed, suspended therein with the help of ropes A and consisting of individual links 5 of the chain, to which the incisors 6 and 7 are L-shaped. The incisors 6 are directed towards the bottom of the trolley, the incisors 7 towards the trolley body. Between links 5 chains, a pyramidal tooth 8 is welded.

The trolley works as follows.

When the trolley 2 is loaded with the mountain mass, the latter arrives at the net-, cu 3 suspended inside the car 2 on the ropes A and lying on its bottom 1. Only a small part of the rock mass entering the car 2 passes through the link 5 of the grid 3 directly to the bottom 1 trolleys 2. However, the L-shaped incisors directed toward the bottom 1 of trolley 2-, and the pyramidal teeth 8, reinforced between links 5 of the net 3, which are in direct contact with bottom 1. This weakens the grip between the adjacent areas of the sticking layer and grip with the body of the trolley. The rest of the forge mass is located above the grid 3. The railroad train composition moves at an uneven speed, with stops and moving, therefore, constantly in motion, inertia forces arise, which, acting on grid 3, cause it to move inside the trolley

Due to the movement of the links 5 of the chain with the L-shaped cutters 6 and 7 of the L-shape and the pyramid teeth 8 fixed on them, the connection between the Mountain mass and the bottom 1 of the trolley 2, which could have formed over short intervals of uniform movement of the trolleys, is destroyed. When unloading the trolley 2 in the tipper, the mesh 3 moves in the direction from the trolley 2, stripping the bottom 1 and the side of the adhering rock mass with the incisors 6 and 7 of the L-shaped form and the teeth 8 of the pyramid shape.

In addition, the movement of the grid contributes to the ejection of the rock mass from the body of the trolley 2, self-cleaning of chain links. In its extreme position during unloading, the grid 3 does not extend beyond the body. When the tilter returns to its original position, the grid 3 returns to the bottom 1 of the trolley 2 and the incisors 6 and 7 are L-shaped, the pyramidal teeth 8 again clean the body and destroy the adhering layer of rock mass, if separate small sections of trolley 2 . The net is made of chain links, which is unsuitable for further use on scraper conveyors.

Claims (1)

Invention Formula A trolley containing a body mounted on the undercarriage, inside of which is placed a net of chains in contact with the bottom and with walls, characterized in that, in order to increase the efficiency of body cleaning from adhering and frozen material, the net is suspended from the body by means of flexible elements and it is equipped with L-shaped cutters rigidly attached to it and pyramidal teeth oriented towards the bottom and walls of the body. eight phi.2
