[0034] Figure 1 Shows the structure of the coal guide device of the utility model Figure 1 . Figure 2 Shows the structure of the coal guide device of the utility model Figure 2 . Figure 3 Shows the working state of the coal guide device of the utility model Figure 1 . Figure 4 Shows the working state of the coal guide device of the utility model Figure 2 .

[0035] like Figure 1 As shown, the coal guide device 100 includes a coal guide plate 01 and a pull rod 02, wherein the pull rod 02 is located on the back of the coal guide plate 01, and one end of the pull rod 02 is hinged to the coal guide plate 01, and the other end of the pull rod 02 is hinged to the coal mining machine body 03. The pull rod 02 helps to prevent the coal guide plate 01 from rotating. In order to enhance the stability of the coal guide plate 01, two pull rods 02 are installed behind the coal guide plate 01, and the two pull rods are arranged in parallel. The coal guide device 100 is arranged on the top of the coal mining machine body 03. In the length direction, one end of the coal guide device 100 is installed on the pedestrian side A, and the other end is installed on the coal wall side B. As shown Figure 3 or Figure 4 As shown, the top of the coal mining machine body 03 is composed of two or more mounting plates 04, and the coal guiding device 100 passes through all the mounting plates 04 in sequence from the pedestrian side A to the coal wall side B at the other end.

[0036] Figure 1In the example, the coal guide device 100 includes seven coal guide plates 01, each of which has two pull rods 02 mounted behind it. The length of the coal guide device 100 can be adjusted by increasing or decreasing the number of coal guide plates 01 depending on the length of the shearer body 03. Furthermore, the length of the coal guide plates 01 is adjustable.

[0037] In another embodiment, the angle α between the coal guiding device 100 and the pedestrian side A is also adjustable. Figure 3 or Figure 4 In the embodiment, one end of the coal guide device 100 is close to the coal wall side B, but does not reach the side wall B1 or B2 of the coal wall side B, and the angle α is relatively small. Figure 3 The other end of the middle coal guide device 100 is installed on the side wall B2 of the coal wall side B, or Figure 4 After the other end of the middle coal guiding device 100 is installed on the side wall B1 of the coal wall side B, the included angle α is increased, the effective area of ​​coal guiding is increased, and the coal guiding effect is improved.

[0038] In yet another embodiment, Figure 2 As shown, a top plate 05 is provided on top of the shearer body 03. One end of a pull rod 02 is hinged to the coal guide plate 01, and the other end of the pull rod 02 is hinged to the top plate 05. The coal guide plate 01 and the top plate 05 are hinged via a connecting shaft 06. The provision of the top plate 05 avoids the need for mounting holes on the shearer body 03, effectively protecting the integrity of the shearer body 03.

[0039] The length of the pull rod 02 is variable, so that the angle β between the coal guide plate 01 and the coal mining machine body 03, or between the coal guide plate 01 and the top plate 05 can be adjusted according to different working environments of the coal mining machine. Figure 2 As shown, the included angle β is 90 degrees, which is suitable for working scenes with large coal mining space. If the coal mining space is small, the included angle β of different angles can be set by adjusting the connecting shaft 06 to adapt to different working scenes.

[0040] When the working surface is tilted, such as when the coal mining machine body 03 is higher on the left and lower on the right, Figure 3 As shown, one end of the coal guide device 100 is installed on the higher side A1 of the pedestrian side A, and the other end is installed on the lower end B2 of the coal wall side B. When the coal and gangue roll from left to right, the coal and gangue are prevented from rolling toward the pedestrian side, ensuring the safety of the pedestrian side. On the contrary, if the coal mining machine body 03 is lower on the left and higher on the right, as shown in FIG. Figure 4 As shown, one end of the coal guiding device 100 is installed on the higher side A2 of the pedestrian side A, and the other end is installed on the lower end B1 of the coal wall side B. When the coal and gangue roll from right to left, the coal and gangue are prevented from rolling toward the pedestrian side, ensuring the safety of the pedestrian side.

[0041] To sum up, the coal guiding device of the utility model has a simple structure, is easy to install, and prevents coal gangue from turning over to the pedestrian side; when the coal and gangue roll on the top of the machine body, it guides the coal and gangue, allowing the coal and gangue on the top of the machine body to flow along the coal guiding device to the coal wall side, thereby achieving the coal cleaning effect.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
