Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] A shearer coal baffle, comprising an arc-shaped coal baffle 6, an integrally formed jib half-ring 2 and an integrally formed jib half-ring 4; the jib half-ring 4 includes an arc surface structure 42 and a rectangular frame structure 41, the rectangular frame structure 41 is composed of a strip-shaped cylinder, a strip-shaped cuboid or a strip-shaped triangle, and the section of the strip-shaped triangle is an equilateral triangle, and one side of the triangle perpendicular to the ground. When one side of the triangle is set vertically to the ground, one of the apexes of the triangle is facing the coal discharge direction, which reduces the friction between the coal and the jib half-ring 4, and improves the overall coal passing capacity. The rectangular frame structure replaces the The connection method of a thicker connecting rod in the prior art, on the basis ...

The invention discloses a coal blocking plate. The coal blocking plate comprises a coal blocking plate of an arc-shaped structure, an arm frame semi-ring of an integrated forming structure (2) and an arm frame semi-ring of an integrated forming structure (4), wherein the arm frame semi-ring (4) comprises an arc surface structure and a rectangular frame structure, and the arc surface structure and the rectangular frame structure are integrally formed; the rectangular frame structure is connected with the coal blocking plate in the arc-shaped structure, a coal transporting passage is constituted, and a ring which consists of the arm frame semi-ring (2) and the arm frame semi-ring (4) sleeves on a roller of a coal cutter in a rotating manner. According to the coal blocking plate disclosed by the invention, the space of a coal transporting passage at the bottom of the coal cutter is enlarged, so that the coal cutter has a better coal charging effect, and the stability of the structure is improved by the integrated formed structure.
Description
technical field [0001] The invention relates to a mechanized coal shearer suitable for underground coal mines, in particular to a coal retaining plate for the coal shearer. Background technique [0002] With the extensive development of mechanical technology, coal mining machinery has become the main mechanical equipment for mechanized coal mining operations, mainly used to complete coal dropping and coal loading operations. The drum shearer is the most widely used coal mining machine at present. The shearer drives the roller installed on the rocker arm through the motor to rotate the roller. The picks on the rotating roller will cut the coal body at a certain angle. The shearer moves left and right on the conveyor through the traction device. , so that the drum cuts into the coal wall. Relying on a certain angle on the drum blades to achieve the effect of coal loading. However, due to the difference in coal quality, the rotation angle of the drum is difficult to control,...
