Coal auxiliary transportation system for coal mine

Abstract

The invention relates to a coal auxiliary transportation system for a coal mine. The coal auxiliary transportation system for the coal mine comprises a bottom frame part, the bottom frame part is fixedly connected with a first conveying device, a bearing box and an output box which are obliquely arranged, the bearing box communicates with the output box, the output box is located on the higher side surface of the bearing box, and the upper end surface of the first conveying device is the box bottom of the bearing box and the output box; and an auxiliary feeding device is arranged between the bearing box and the output box, the auxiliary feeding device limits the height of materials conveyed from the bearing box to the output box, an output opening is formed in the bottom of the output box, the bottom frame part is further connected with a second conveying device, and the materials are input into the output box from the bearing box through a first output device and are discharged from the output opening of the output box. The coal auxiliary transportation system for the coal mine is simple in structure, convenient to operate, flexible to use, capable of adjusting the material carrying amount of the conveying devices in unit area, capable of effectively prolonging the service life of the conveying devices and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of coal material transportation, and in particular relates to an auxiliary coal material transportation system for coal mines. Background technique [0002] In the traditional coal transportation system, the first stage requires workers to shovel the coal to be transported directly on the conveyor belt for transportation, or directly output the coal to the conveyor belt for transportation through the coal separator , neither of the two methods can well control the amount of coal material per unit area of ​​the conveyor belt. The general mechanical system uses a height limit rod or a limit block with a certain height to prevent excessively high (in the unit area) coal material from passing through. The function can effectively clean up the rough feeding process, but the hard height limit rod may be easily damaged due to too much coal material, and it is easy to block the coal material from accumulating, so th...

The general mechanical system uses a height limit rod or a limit block with a certain height to prevent excessively high (in the unit area) coal material from passing through. The function can effectively clean up the rough feeding process, but the hard height-limiting rod may be easily damaged due to excessive coal materials, and it is easy to block coal materials and accumulate, so the adaptability is poor
