[0016] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0017] A material bin bottom air box activation device, in combination with Figures 1 to 2 as shown, includes a material bin 1, a conical part 2, an air box 3, a filter cloth 4, a filter side cloth 5, a bellows cover 6, an adjustment mechanism. A connecting rod 7, an adjusting rod 8, a connecting block 9, a first gear 10, a second gear 11, a driving motor 12, a reducer 13, a connecting shaft 14, a connecting frame 15, a vibration motor 16.

[0018] The material bin 1 includes a cylindrical part in the upper part and a conical part 2 in the lower part.

[0019] A plurality of blowing mechanisms and vibration motors 16 are arranged on the conical part 2 of the material bin 1, and the blowing mechanisms and the vibration motors 16 are arranged at intervals; and the blowing mechanisms and the vibration motors 16 are evenly distributed on the same horizontal plane.

[0020] The blowing mechanism includes an air box 3 arranged on the side wall of the conical part 2, and the air box 3 is connected to a gas source. The air box 3 is connected to the conical part 2 through a bellows cover 6, and a filter side cloth 5 is arranged outside the bellows cover 6 to prevent materials from entering the bellows cover 6.

[0021] The air box 3 is connected with an adjusting mechanism for adjusting the air outlet direction of the air box 3, and the controlled end of the adjusting mechanism is connected to the PLC controller. A filter cloth 4 is covered on the air outlet of the air box 3 to prevent materials from entering the air box 3.
