Hopper device for underground ore transfer cars

Abstract

The invention belongs to the field of mine borehole operation machines, and specifically relates to a hopper device for underground ore transfer cars. The hopper device for underground ore transfer cars comprises a hopper which is fixed at the rear part of a car body and can carry out a pitching motion on the car body; and the hopper device also comprises an ore blocking unit, the ore blocking unit comprises an ore blocking plate and an extending end, the ore blocking plate is used for blocking an opening part of the hopper, the extending end is formed through extending to the direction of the front part of the car body along at least one end part of the ore blocking plate, a hinged running fit is formed between the extending end and the outer wall of the hopper, the extending end and the car body are hinged through a hinge, the hinge point on the extending end is located in a position between a hinged point on the extending end and the top of the extending end, when the hopper is in an initial state, the ore blocking plate is blocked at the opening part of the hopper, and when the hopper is in a pitch-up unloading state, the ore blocking plate is drawn by the hinge, so that an open mouth for enabling ores to fall is formed between the ore blocking plate and the opening of the hopper. The hopper device is high in conveying efficiency, and can effectively reduce and even avoid the occurrence of an ore falling phenomenon in the process of transportation.

Description

technical field [0001] The invention belongs to the field of underground mine operation machinery, and in particular relates to a hopper device for an underground mine transport vehicle. Background technique [0002] Underground mining vehicles are mainly used in underground mines, mainly for loading, transportation and dumping operations, and can also be used in roads, railways, tunnels and construction projects, suitable for harsh working conditions, narrow, low and muddy work sites noodle. Traditional LHDs are often only equipped with hoppers for loading without related ore barriers for gear hopper openings, which have the following defects: the head is too small, and if you want to increase the carrying capacity of a single vehicle, you only need to It can be solved by increasing the hopper.

Problems solved by technology

Traditional LHDs are often only equipped with hoppers for loading without related ore barriers for gear hopper openings, which have the following defects: the head is too small, and if you want to increase the carrying capacity of a single vehicle, you only need to It can be solved by increasing the hopper. However, due to the influence of many environments such as underground roadways, it is obviously impractical to blindly increase the hopper; secondly, when loading and transporting ore, there is no blocking device, and the Underground roadways are mostly potholed roads, and the ore is easy to fall from the hopper when the vehicle is running bumpy. The details are as follows: figure 1 As shown, it not only further aggravates the potholes and muddyness of the road surface, which will affect the transportation of subsequent operating equipment, but also the hard ore that falls on the road surface will easily scratch the tires of vehicles moving forward, posing a great safety hazard
