Problems solved by technology

[0002] In order to expand the range of mining height, adapt to the change of coal seam thickness and the change of roof and floor, coal shearer usually uses coal cutting mechanism, and in the coal cutting mechanism, the coal cutting drum is the key device. In order to cooperate with the coal cutting drum to complete the coal loading process, A coal retaining board is required. The disadvantage of the traditional coal retaining board is that the coal retaining effect is not good, coal leakage is easy to occur, and the mechanism is relatively complicated, and the energy consumption is high

Embodiment Construction

[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] see figure 1 , The present invention includes a body 10, a bracket 3 on the body 10, the body 10 is connected to a support 8 by a connecting rod 7, and the bracket 3 is fixedly connected to the arc plate 2 by a screw 1 for easy replacement; the body 10 is fixedly connected to a gland 6. One end of the connecting rod 7 is rotatably connected with the support 8 via a pin 9, and the other end of the connecting rod 7 is rotatably connected with the body 10 via a pin 4; the connecting rod 7 and the body 10 are provided with a lug 5.

[0013] The connecting rod mechanism formed by the bracket, the arc plate and the connecting rod of the present invention enables the arc plate to move parallel to the bottom plate at any height of the drum within the adjustment range, so as to adapt to the work of the shearer and ensure a good coal loading effect ...

Abstract

The invention relates to a spill plate of a coal mining machine. The spill plate comprises a body and a bracket arranged on the bracket. The spill plate is characterized in that the body is connected with a support by a connection rod; the bracket is fixedly connected with an arc-shaped plate by a screw; the body is fixedly connected with a pressing cover. Compared with the traditional spill plate of the coal mining machine, the spill plate of the coal mining machine has the advantages of simple structure and low energy consumption, and convenient to detach and replace and simple to operate. The bracket is connected with the arc-shaped plate and the connection rod to form a connection rod mechanism so that the arc-shaped plate can move in parallel relative to a bottom plate under any roller height in an adjustable range, and furthermore, the working of the coal mining machine is adapted and the good coal filling effect is guaranteed.

Description

Technical field: [0001] The invention relates to the field of coal mining equipment, in particular to a coal shearer. Background technique: [0002] In order to expand the range of mining height, adapt to changes in coal seam thickness and roof and floor changes, coal shearers usually use coal cutting mechanisms. In the coal cutting mechanism, the coal cutting drum is a key device. In order to cooperate with the coal cutting drum to complete the coal loading process, It is necessary to provide a coal baffle. The disadvantage of the traditional coal baffle is that the coal retaining effect is not good, coal leakage is prone to occur, and the mechanism is relatively complicated and the energy consumption is high. Summary of the invention: [0003] In view of the above-mentioned shortcomings of the traditional coal baffle, the applicant has conducted research and improvement, and provided a coal baffle of a coal shearer, which has the characteristics of simple structure, simple opera...
