[0032] In the above technical solution, the servo motor 3 drives the discharging roller 2 to rotate, so as to avoid the material blocking in the frame body 1.
[0033] Through the displacement of the plug-in plate structure 4, the discharging gap can be adjusted, and the feeding speed to the coal feeder can be changed.
[0034] The insertion of the plug-in plate structure 4 can also cooperate with the discharging roller 2 to complete the closure and stop the feeding.

[0038] In the above technical solution, the height of the vertex of the material distribution surface 23 is located in the outer circle diameter of the roller body 21.
[0039] The design of this structure has the advantages that when the plug-in plate structure 4 moves close to the outer circular surface of the roller body 21, the coal powder cannot be discharged between the roller body 21 and the plug-in plate structure 4, but when the roller body 21 rotates to make the material distribution surface 23 upward, the discharging gap is formed between the plug-in plate structure 4 and the material distribution surface 23, and with the continuous rotation of the roller body 21, the gap is gradually closed, thereby realizing the intermittent feeding effect.
[0040] The angle α of the material distribution surface 23 is 90-135°.
[0041] In the embodiment, the angle a of the distribution surface 23 is 90 degrees

[0045] The inspection cover plate 441 facilitates the inspection of the surface wear degree of the plugboard 42 and facilitates the adsorption treatment of dust particles in the outer shell 41 by a dust suction device.
