Description

Technical Field

[0001] The utility model relates to the technical field of roadheader shovel plates, in particular to a coal mine roadheader shovel plate. Background Art

[0002] Coal mine roadheaders are machines used to excavate tunnels on flat ground. They are categorized as open-type and shield-type, and primarily consist of a traveling mechanism, a working mechanism, a loading mechanism, and a transfer mechanism. As the traveling mechanism advances, the cutting head in the working mechanism continuously crushes rock. The roadheader's shovel scoops the coal removed by the cutting head onto the shovel. A star wheel assembly on the shovel then scoops the crushed coal onto a conveyor in the chute between the shovels, transporting the coal. The roadheader's shovel effectively clears mud and rock obstructions along the road ahead, enabling the machine to move forward stably. The roadheader's shovel is essential for the machine's forward motion. The existing announcement number is CN 220267701 U, which is a shovel board of a coal mine roadheader. The first motor can drive the driving gear to rotate, and the driving gear can cooperate with the driven gear to rotate the first roller. The rotation of the first roller can drive the reel to rotate, which can drive the coal slag inside the coal slag pair in front of the star wheel body and can cooperate with the star wheel body to increase the efficiency of the star wheel body in conveying coal slag. However, the position of the first roller on the above-mentioned shovel board is fixed relative to the shovel board. When the amount of coal shoveled changes, the position cannot be adjusted according to needs to control the feed amount of coal material, which causes troubles in use. Utility Model Content
