Abstract

The invention provides a coal seam crushed coal reducing cutting device. The coal seam crushed coal reducing cutting device comprises a cutting guiding part and a taking-out part, the taking-out partis arranged on one side of the cutting guiding part, and the cutting guiding part comprises a cutting machine, a coal seam, a transverse cutting rod, a connecting head, a backflow disc, a flow-dividing fan, a water delivery disc, a side face cutting rod and a dredging drill; and the coal seam is arranged on one side of the cutting machine, the transverse cutting rod is arranged on one side of thecutting machine, the connecting head is arranged on one side of the transverse cutting rod, the backflow disc is arranged at one end of the connecting head, the flow-dividing fan is arranged on the surface of the transverse cutting rod, the water delivery disc is arranged inside the transverse cutting rod, the side face cutting rod is arranged at one end of the transverse cutting rod, and the dredging drill is arranged at one end of the side face cutting rod. The upper side and the lower side of the coal seam can be rotatably cut through the transverse cutting rod, cut crushed coal enters a groove of the transverse cutting rod and drives the flow-dividing fan to rotate, the crushed coal is pressed by the flow-dividing fan while driving the flow-dividing fan to rotate, and thus the crushedcoal is prevented from being splashed around.

Description

technical field [0001] The invention belongs to the technical field of coal seam less crushed coal cutting structure, and more specifically relates to a coal seam less crushed coal cutting device. Background technique [0002] During the mining process of coal mines, a large number of broken coal, floating coal and safety coal pillars are left in the goaf or in the mining roadway. The broken coal and floating coal have a large oxidation surface area and strong oxygen absorption capacity. A large number of cracks increase the oxidation surface area. When the gob is not tightly sealed or the ventilation conditions of the roadway are not good, oxygen will be continuously supplied, and a large amount of heat energy will be generated after coal oxidation. If it cannot be dissipated in time, it may lead to mine Coal spontaneously combusts. Based on the above description, most of the existing coal mines are mined by the shearer and then the crushed coal is transported out, resulti...
