Background
Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. Need transport materials such as colliery at coal mining in the pit, do not have any dustproof protection above the current conveyer, can be blown down a large amount of buggy by wind in well head department, cause the waste on the one hand, also the polluted environment on the one hand.

fig. 2 is a side view of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in fig. 1-2, a coal mining dust-free conveying device comprises left and right cover plate mechanisms 1 and 2 which are identical in structure and are respectively and symmetrically arranged on two sides of the upper part of a mine car, wherein the left and right cover plate mechanisms respectively comprise an upper power cylinder 3, a lower power cylinder 4, a chain 5, a synchronizing shaft 6, a first cover plate 7, a second cover plate 8, a third cover plate 9, a first buffer cylinder 10 and a second buffer cylinder 11; the upper power cylinder and the lower power cylinder are fixed on the mine car 12; the synchronizing shafts are arranged on two sides of the upper part of the mine car and are arranged along the length direction of the mine car, one end of each synchronizing shaft is provided with a chain wheel 13, the chain wheels are connected with the chains in a winding way, one end of the chain is connected with the piston rod of the upper power cylinder, the other end is connected with the piston rod of the lower power cylinder, the lower part of the first cover plate is fixedly connected with the synchronizing shaft, the upper part of the first cover plate is hinged with the lower part of the second cover plate, the upper part of the second cover plate is hinged with the upper part of the third cover plate, the middle part of the second cover plate is provided with a connecting seat 14, the lower part of the first buffer oil cylinder is hinged with the inner side of the first cover plate, the piston rod of the first buffer oil cylinder is hinged with the lower part of the connecting seat, the lower part of the second buffer oil cylinder is hinged with the upper part of the connecting seat, and a piston rod of the second buffer oil cylinder is hinged with the inner side of the third cover plate. The upper power cylinder and the lower power cylinder are positioned at the front part or the rear part of the mine car.
