Coal material discharging device of coal engineering vehicle

Abstract

The invention provides a coal material discharging device of a coal engineering vehicle, which comprises a mounting threaded sleeve, a stepped ring and caster wheels; wherein a mounting plate is of arectangular plate structure, a rotating plate is arranged on the left side and right side of the lower position of the rear end surface of the mounting plate respectively, an underframe is rotatably arranged in the rotating plate in a mode that a rotating shaft penetrates through the rotating plate, and four caster wheels are arranged on the bottom side of the underframe of the rectangular frame body; different from other similar structures, a screen seat with a filtering function is arranged at the top opening position of a feeding guide seat in a rotating and hinge mode, and when a worker standing on a transport vehicle guides coal into a ground loading device through the guide seat according to actual conditions, the coal with larger particles can be filtered, vibration is generated ina manual elastic pressing mode, the discharging speed of the fine coal cinder is improved, and also, the screen seat is turned over to enable the large-particle coal blocks in the screen seat to fallonto transportation devices at other positions, so that classified charging is achieved, and the functional structure is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mine unloading devices, and more specifically relates to a coal material unloading device for a coal engineering vehicle. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological la...

Problems solved by technology

[0003] Based on the above description, the designer found that after the trailer of the transport vehicle arrives at the coal unloading site, when the coal is unloaded downward, the direct batch unloading method is often used, and the synchronous distinction between coal lumps and cinders cannot be carried out, which is necessary for small purchases. When the fine coal slag comes to buy coal, it is necessary to re-separate the fine coal slag from the unloaded coal pile. Therefore, this design aims at this market demand, and designs a model that can be attached when unloading coal according to actual needs. Auxiliary coal unloading device on the coal mine transport pallet and capable of filtering coal slag to improve flexibility and practicability
