Buffering material receiving device for coal mine

Abstract

The invention discloses a buffering material receiving device for a coal mine. The buffering material receiving device comprises a material receiving box, a feeding port is formed in the top end of the material receiving box, a material receiving plate and a buffering air cylinder are hinged to one side of the inner wall of the material receiving box, the material receiving plate is located at the bottom end of the feeding port, the bottom end of the buffering air cylinder is located at the bottom end of the material receiving plate, connecting lugs are hinged to the top end of the material receiving plate, sliding blocks are fixedly connected to the top ends of the connecting lugs, rolling wheels are rotatably connected to the top ends of the sliding blocks, the sliding blocks matched with the sliding blocks are arranged at the bottom end of the material receiving plate, the sliding blocks are slidably connected with sliding grooves through the rolling wheels. The sliding blocks are additionally arranged at the top end of the connecting lug, the sliding grooves drive the rolling wheels to roll, meanwhile, the rolling wheels drive the sliding blocks to move downwards, the sliding blocks compress the top end of the buffer air cylinder through the connecting lugs, when materials leave the surface of the material receiving plate, the buffer air cylinder drives the material receiving plate to reset, and under the action of the sliding blocks and the sliding grooves, downward moving, resetting and moving stability of the material receiving plate is guaranteed; under the action of the rollers, the moving friction force between the sliding blocks and the sliding grooves is reduced.

Description

technical field [0001] The invention relates to the technical field of coal material receiving in coal mines, in particular to a buffer material receiving device for coal mines. Background technique [0002] Coal is an area where human beings exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. The scope of coal mines includes a large area above ground, underground and related facilities. A buffer receiving device is required during coal transportation. [0003] In the existing buffer material receiving device, the moving friction between the material receiving plate and the cylinder is relatively large, which brings inconvenience to the movement of the material receiving plate, a...

Problems solved by technology

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a buffer material receiving device for coal mines, which can solve the problem of the large frictional force between the material receiving plate and the cylinder in the existing buffer material receiving device, which brings problems to the movement of the material receiving plate. Inconvenient, and the lack of protection on the top surface of the material receiving plate, it is easy to cause wear and tear during the continuous material receiving process, and the technical problem of short service life
