However, in general, the coal baffle adopts a fixed structure, which makes the coal baffle area unable to be adjusted, and the falling position of the coal blocks is random. If the plate area of the coal baffle cannot completely block the coal blocks, the coal blocks will be missed, reducing the coal mining efficiency. At the same time, if the coal blocks enter the coal miner, it will increase the risk of equipment wear and damage.
[0003] Therefore, in order to solve the defect that the coal retaining plate cannot adjust the coal retaining area, it is necessary to propose a coal retaining plate for a coal mining machine. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In order to solve the technical problem of how to adjust the coal retaining area of the coal retaining plate, please refer to Figure 1-Figure 5 , this embodiment provides the following technical solutions:
[0023] A coal baffle for a coal mining machine comprises a fixed baffle 1, a movable baffle 2 rotatably arranged in the fixed baffle 1 and a coal storage bag 3 sleeved on the bottom end of the fixed baffle 1. The fixed baffle 1 is arranged in an irregular circular shape and is hollow inside. Mounting discs 12 are symmetrically welded at the center of the left and right ends of the fixed baffle 1. A spur gear 14 is rotatably arranged on the side wall of the fixed baffle 1. The spur gear 14 is fixedly connected to a motor 13 through a transmission rod. The motor 13 is fixedly connected to the side wall of the fixed baffle 1 through a mounting plate 15.
[0024] The movable baffle 2 is arranged in an irregular circle with a hollow interior. Connecting sleeves 22 are symmetrically welded at the center of the left and right ends of the movable baffle 2. The connecting sleeve 22 is movably connected to the mounting disc 12 and penetrates the mounting disc 12. One end of the connecting sleeve 22 extends to the outside of the mounting disc 12, and a gear ring 23 is fixedly sleeved on the end of the connecting sleeve 22 located outside the mounting disc 12, and the gear ring 23 is meshed with the spur gear 14.
[0025] Specifically, when the angle of coal falling is too large and the coal baffle cannot completely catch the coal block, the motor 13 is started, and the motor 13 drives the spur gear 14 to rotate, and the spur gear 14 drives the gear ring 23 meshing with it to rotate, and the gear ring 23 then drives the connecting sleeve 22 fixed thereto to rotate, and the connecting sleeve 22 then drives the movable baffle 2 fixed thereto to rotate, so that the movable baffle 2 can extend from one end of the fixed baffle 1, thereby increasing the coverage area of the side end of the coal mining machine drum, thereby increasing the coal blocking area.
[0026] In order to solve the technical problem of how to clean the coal blocks stuck to the inner wall of the coal baffle, please refer to Figure 3-Figure 5 , this embodiment provides the following technical solutions:
[0027] A feed plate 16 is provided at the bottom end of the fixed baffle 1, a sleeve frame 11 is welded at the outer end of the feed plate 16 of the fixed baffle 1, and a coal storage bag 3 is arranged on the sleeve frame 11. A scraper 21 is provided at the bottom end of the movable baffle 2, and the scraper 21 is closely connected to the inner wall of the fixed baffle 1.
[0028] Specifically, the motor 13 is started to make the movable baffle 2 rotate out of the fixed baffle 1, and then the direction of the motor 13 is adjusted to reverse. At this time, the movable baffle 2 rotates back into the fixed baffle 1 and drives the scraper 21 to scrape the inner wall of the fixed baffle 1 to remove the coal blocks stuck on the inner wall of the fixed baffle 1. Then the coal blocks are pushed by the scraper 21, guided by the unloading plate 16, and finally fall into the coal storage bag 3.
[0029] The opening of the coal storage bag 3 is provided with an elastic rope, so that the bag can be sleeved outside the sleeve frame 11 and can be easily disassembled to take out the coal blocks inside.
[0030] Working principle: The coal baffle plate of the coal mining machine is used. When the angle of coal falling is too large and the coal baffle plate cannot completely catch the coal block, the motor 13 is started, and the motor 13 drives the spur gear 14 to rotate. The spur gear 14 drives the connecting sleeve 22 to rotate through the gear ring 23, and the connecting sleeve 22 drives the movable baffle plate 2 to rotate, so that the movable baffle plate 2 can extend from one end of the fixed baffle plate 1, increase the area covered on the side end of the coal mining machine drum, and thus increase the coal blocking area. If the inner wall of the coal baffle plate is stuck with coal blocks, the motor 13 is started to make the movable baffle plate 2 rotate out of the fixed baffle plate 1, and then the direction of the motor 13 is adjusted to reverse it. At this time, the movable baffle plate 2 rotates back into the fixed baffle plate 1, and drives the scraper 21 to scrape the inner wall of the fixed baffle plate 1 to remove the coal blocks stuck on the inner wall of the fixed baffle plate 1. Then the coal blocks are pushed by the scraper plate 21, guided by the unloading plate 16, and finally fall into the coal storage bag 3.
