Abstract

The invention relates to a self-dumping mine wagon body with a hinged bottom for emptying from below, which is used for transporting rocks. The invention solves the sealing of the bottom (1) of the body against the side walls (2 and 3) of the body, where the bottom of the body has three of its sides bent towards the side walls (2 and 3) of the body, of which two opposite sides of the bottom (1) of the body rest on the contact strips (6), firmly connected to the outer sides of the transverse side walls (2) of the body. Another bent side of the bottom (1) of the body is connected by hinges (4) to the longitudinal side wall (3) of the body. The remaining flat side of the bottom (1) of the body is provided with an adjustable sealing strip (7) of elastic material, which rests on the inner vertical side of the longitudinal side wall (3) of the body. An illustration of the body according to the invention is shown in Fig. 1 and 2 of the attached drawing. The subject of the invention can be used in the transport of rocks that are dumped into a common container, especially in mining operations.

Description

The present invention relates to a tipping lorry with a hinged bottom for emptying from below, in which a sealing of the hinged bottom to the side walls of the hull is provided.

In the hinged tipper lorries with hinged bottom, the lower edge of the side walls of the hull abuts against the horizontal edge of the hull bottom, thereby forming a joint which, in an alternative embodiment, is doubled by hemming the lower edge of the hull side walls.

The disadvantage of these bodies is that the contact surfaces between the lower edges of the side walls of the bucket and the bottom of the bucket show insufficient tightness due to sticking of transported rocks, which does not allow the bottom of the bucket to abut the bottom edges of the sides of the bucket rocks by the gap between the side walls and the bottom of the hull.

These drawbacks of the prior art are overcome by the tipping-off bucket of the bottom hopper for emptying under the bottom of the invention, wherein the bottom of the bucket has three of its sides bent toward the side walls of the bucket, where one of the bent sides is connected to hinges rigidly connected to one longitudinal side wall of the hull above its lower edge and the other two transverse sides of the hull bottom provided as abutment surfaces against the seating strips; sealing strip made of flexible material.

The advantage of the hopper of the self-dumping mining wagons according to the invention is that the bearing surfaces of the hopper bottom and the side walls of the hopper are provided in places where no sticking of the transported rocks occurs and the actual sealing between the side wall and the hopper bottom is provided with on which there is no sticking of transported rocks.

In this way, the bottom of the bucket is completely closed against the side walls of the bucket, so that the transported rock is not discharged on the track, which furthermore has a positive effect on reducing dust and increasing safety in underground mines.

The body of the self-discharging mining carriage according to the invention is illustrated by way of example in a schematically drawn drawing, wherein Fig. 1 shows a longitudinal section of a self-discharging mining carriage;

cross-section of a self-discharging mining truck.

According to an exemplary embodiment, the tipper of a self-dumping mining wagon consists of the bottom of the tipper J, two transverse side walls 2 of the tipper and two longitudinal side walls J of the tipper. The bottom J of the body has three of its sides bent towards the transverse and longitudinal side walls 2 and J of the body to which the hinges J are connected which are fixedly connected to one longitudinal side wall J of the body above its lower edge. Both bent transverse sides of the hull bottom J are arranged in the form of bearing surfaces J, which are in position against the seating strips 6 firmly connected and transverse side walls 2 of the hull above their lower edge, the fourth straight side of the hull bottom J is provided with adjustable the bottom of the body of the body, which is made of flexible material and abuts the vertical surface of the adjacent side wall of the body of the body. The longitudinal side walls J of the bucket are provided with guides fi and the bottom 1 of the bucket is rigidly connected to the axles of the traveling wheels J of the self-discharge mining wagon.

The mine wagon of the present invention is emptied at a discharge station in which the mine wagon 8, with its guides 8, drives the support rollers 10 along which the self-discharge mine wagon is carried in the travel direction. Above the hopper hopper, the wheels J of the hopper wagon leave the rails JJ and the bottom J of the hopper dump truck is folded around the hinge J, whereupon the rock is discharged into the hopper. Further movement of the mining self-hopper on the support rollers JO causes the lifting mechanism of the hopper to raise the bottom J of the mining self-hopper to a horizontal plane and to position the traveling wheels J on the rails JJ of the track.
