[0020] Pour the coal into the distribution box 1. After entering the distribution box 1, the coal will fall to the top of the distribution plate 2. During this process, the rotating motor 44, the rotating rod 43, the protrusion 45 and the telescopic rod 42 in the dispersion component 4 will drive the distribution plate 2 to rise and fall along the inner wall of the distribution box 1, so that the coal accumulated on the top surface of the distribution plate 2 is dispersed, which is conducive to improving the distribution efficiency.

[0022] See also Figure 1 , Figure 2 and Figure 3The flow control assembly 3 includes two support frames 31 fixedly connected to the bottom end of the cloth plate 2, and the opposite sides of the two support frames 31 are fixedly connected with a slide bar 32. The bottom end of the cloth plate 2 is located on one side of the support frame 31 and is rotatably connected with two first transmission plates 33. The two first transmission plates 33 are rotatably connected, one end of the first transmission plate 33 is rotatably connected with a second transmission plate 34, two adjacent second transmission plates 34 are rotatably connected, one end of the second transmission plate 34 is rotatably connected with a third transmission plate 35, and two adjacent third transmission plates 35 are rotatably connected. The bottom end of the second transmission plate 34 is rotatably connected with a slide seat 36, and the bottom end of the third transmission plate 35 is rotatably connected with an adjustment seat 37. One side of the adjustment seat 37 is fixedly connected with an electric push rod 38, and the electric push rod 38 is fixedly connected to the support frame 31. The slide seat 36 and the slide bar 32, and the adjustment seat 37 and the slide bar 32 are all slidably connected. The second transmission plate 34 and the third transmission plate 35 are rotatably connected with baffles 39 at the top. The electric push rod 38 connected to one side of the support frame 31 is started to drive the adjustment seat 37 to slide along the surface of the slide rod 32, thereby changing the angle between the two third transmission plates 35 connected to the bottom end of the adjustment seat 37 and pushing the second transmission plate 34 to change the angle between the two adjacent second transmission plates 34, thereby pushing the slide 36 connected to the second transmission plate 34 to slide in the same direction along the surface of the slide rod 32, thereby changing the angle between the two first transmission plates 33 connected to the bottom end of the distribution plate 2, thereby pushing the several baffles 39 connected to the top of the adjustment seat 37 and the slide 36 to slide along the bottom end of the distribution plate 2 and block the bottom end of the distribution hole, so that the flow rate of coal distribution can be controlled according to the actual situation to prevent the efficiency and effect of coal selection from being affected by excessive coal flow.

[0024] A sealing ring 5 is fixedly connected to the side of the distribution plate 2, and the diameter of the distribution hole is larger than the maximum particle size of the coal. The sealing ring 5 can improve the sealing between the distribution plate 2 and the distribution box 1, thereby preventing the coal from getting stuck in the gap between the distribution plate 2 and the distribution box 1. The diameter of the distribution hole is larger than the maximum particle size of the coal, which can prevent the coal from clogging the distribution hole.

[0025] The side of the material distribution box 1 is fixedly connected with an anti-overflow box 7, and the top surface of the anti-overflow box 7 is higher than the top surface of the material distribution box 1.

The buffer spring 6 can prevent the telescopic rod 42 from being damaged by excessive impact force during the descent of the cloth plate 2, thereby helping to extend the service life of the dispersion component 4.

[0027] Specific implementation method: Pour the coal into the distribution box 1, and the coal will fall to the top of the distribution plate 2 after entering the distribution box 1. During this process, the rotating motor 44 will drive the rotating rod 43 to drive the two protrusions 45 to rotate, and the distribution plate 2 will be driven to rise and fall along the inner wall of the distribution box 1 through the extension and retraction of the telescopic rod 42, so that the coal accumulated on the top surface of the distribution plate 2 is dispersed, which is conducive to improving the distribution efficiency;

[0028] The electric push rod 38 connected to one side of the support frame 31 is started to drive the adjustment seat 37 to slide along the surface of the slide rod 32, thereby changing the angle between the two third transmission plates 35 connected to the bottom end of the adjustment seat 37 and pushing the second transmission plate 34 to change the angle between the two adjacent second transmission plates 34, thereby pushing the slide 36 connected to the second transmission plate 34 to slide in the same direction along the surface of the slide rod 32, thereby changing the angle between the two first transmission plates 33 connected to the bottom end of the distribution plate 2, thereby pushing the several baffles 39 connected to the top of the adjustment seat 37 and the slide 36 to slide along the bottom end of the distribution plate 2 and block the bottom end of the distribution hole, so that the flow rate of coal distribution can be controlled according to the actual situation to prevent the efficiency and effect of coal selection from being affected by excessive coal flow.
