Hydraulic adjusting damping device of mine raw coal belt head and working method of hydraulic adjusting damping device

Abstract

The invention discloses a hydraulic adjusting damping device of a mine raw coal belt head and a working method of the hydraulic adjusting damping device, and belongs to the technical field of coal mine equipment. The hydraulic adjusting damping device is arranged on the output side of the belt head, the hydraulic adjusting damping device comprises side plates, a bottom plate, crossbeams, mountinglugs, a hydraulic cylinder and a buffer plate, the two side plates are symmetrically arranged face to face, the bottom plate and a plurality of crossbeams are connected between the two side plates, aplurality of mounting lugs are arranged at the bottoms of the outer walls of the side plates, one end of the hydraulic cylinder is installed on the top surface of the bottom plate through a lug of thehydraulic cylinder, the other end of the hydraulic cylinder is connected with the rear part of the buffer plate through an adapter, the buffer plate slides back and forth on the bottom plate along the guide structure driven by the hydraulic cylinder, and the front end of the buffer plate protrudes out of the front edge of the bottom plate. The technical scheme of the hydraulic adjusting damping device can adjust a corresponding buffer dropping point for raw coal material flow ejected from the changing belt head, and has the better protection effect on a downstream vibrating screen.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a hydraulically adjustable damping device for a mine raw coal belt head and a working method thereof. Background technique [0002] With the continuous development of social economy and science and technology, mine resources are still an important pillar for the development of modern social economy and science and technology. However, in coal mining, because the raw coal material transported by the belt conveyor is too large and heavy, it is very easy to smash the sieve plate of the vibrating screen downstream of the belt conveyor, and it will greatly reduce the life of the vibrating screen. And because the underground environment of the coal mine is poor and there are few tools, it is very troublesome to replace the sieve plate, so the workload is very large and a lot of manpower and material resources are wasted. And the whole coal mining production line needs to b...

AI Technical Summary

Problems solved by technology

However, in coal mining, because the raw coal material transported by the belt conveyor is too large and heavy, it is very easy to damage the sieve plate of the vibrating screen downstream of the belt conveyor, and has a great loss on the life of the vibrating screen.

And due to the poor environment and few tools in the coal mine, it is very troublesome to replace the sieve plate, so the workload is very large, and a lot of manpower and material resources are wasted

In addition, the entire coal mining production line needs to be shut down to replace the sieve plate, which seriously affects the normal production operations of the coal mine.

[0003] At present, buffer damping devices are used in some underground coal mines to buffer the raw coal material flow projected by the belt machine head. However, due to the error between the raw coal material parabola of the belt conveyor and the theory, the dropping point of the existing buffer damping device cannot be based on the raw coal material flow. Adjust the material flow, so that part of the raw coal material flow will directly hit the vibrating screen, reducing the life of the vibrating screen, and the screening effect is poor, affecting coal mine production
