Embodiment Construction
[0014] figure 1 It is a structural schematic diagram of an embodiment of a shearer coal unloading device of the present invention; as figure 1 As shown, the embodiment of the shearer coal unloading device of the present invention comprises a shearer main body, and the top of the shearer main body is hinged with a coal unloading plate 1, and the coal unloading plate 1 has a hinged side and a free side that deviate from each other, and the hinged side Close to the mining side of the shearer body, the free side is away from the mining side of the shearer body.
[0015] In the above scheme, by controlling the rotation of the coal unloading plate 1 to turn up the coal unloading plate 1, under the action of gravity, the coal gangue will slide from the coal unloading plate 1 to the mining side of the shearer, thus avoiding the accumulation of coal gangue. And the problem of slipping to the control end of the shearer to injure the operator. In addition, the coal gangue on the top of...

The invention provides a coal unloading device of a coal cutter, which comprises a coal cutter main body; a coal unloading plate is hinged to the top of the coal cutter main body; the coal unloading plate has a hinging side and a free side which are apart from each other; the hinging side is close to a digging side of the coal cutter main body, and the free side is apart from the digging side of the coal cutter main body. According to the scheme, by controlling the rotation of the coal unloading plate and turning the coal unloading plate upwards, coal and gangue slide to the digging side of the coal cutter from the coal unloading plate under the action of gravity, which avoids the problem that coal and gangue slide to a control end of the coal cutter due to accumulation to damage operators. In addition, coal and gangue at the top of the coal cutter can be cleaned only by turning the coal unloading plate upwards, which shortens the repair cycle of the coal cutter.
Description
technical field [0001] The invention relates to mining machinery technology, in particular to a coal unloading device for a coal shearer. Background technique [0002] In the process of coal mining in the fully mechanized mining face, a large amount of coal gangue is accumulated on the main body of the shearer due to the falling of coal wall and roof gangue. A large amount of coal gangue is accumulated on the top of the main body of the shearer. On the one hand, it takes a lot of time to clean the coal gangue during the maintenance of the shearer, resulting in a prolonged maintenance cycle. On the other hand, the coal gangue accumulated on the top of the main body of the shearer is easy to slip To the operator's side, and cause injury to the operator, especially when the roof is broken, large pieces of coal gangue may roll down and cause serious accidents. [0003] It can be seen from the above that it is a technical problem to be solved by those skilled in the art to solve...
