DETAILED DESCRIPTION

[0022] like Figure 1-4 In the embodiment, the pneumatic material guiding structure based on the unloading cooperation of the dust collecting bin comprises an air pump 1, a first fixing seat 2 is provided at the bottom of the air pump 1, and an air outlet port of the air pump 1 is connected to a material guiding pipeline 3;

[0023] The material guide pipeline 3 includes a guide pipe 4, which is connected to the air outlet port of the air pump structure through a first connecting flange 5. An acceleration section 6 is provided on the guide pipe 4. The acceleration section 6 on the guide pipe 4 is fixedly connected to a discharge connecting pipe 8. A second connecting flange 9 is provided on the discharge connecting pipe 8. The guide pipe 4 is provided with a discharge auxiliary structure.

[0024] In the preferred solution, the unloading auxiliary structure includes a second fixed seat 12, on which a motor 13 is arranged, the output end of the motor 13 is connected to one end of a rotating shaft 14 through a coupling, the other end of the rotating shaft 14 passes through the guide tube 4 and enters the unloading connecting pipe 8, and a plurality of stirring blades 16 are arranged on one end of the rotating shaft 14 located at the unloading connecting pipe 8. The stirring and crushing of the materials can break up the compacted or bonded material blocks, reduce the burden of pneumatic conveying, and make the conveying process more stable.

[0025] In a preferred embodiment, the rotating shaft 14 is connected to the connecting seat 10 provided on the guide tube 4 through the connecting bearing 11, and a shielding cover 15 is provided on the rotating shaft 14 to match the connecting bearing 11, thereby shielding and protecting the gap between the connecting bearing 11 and preventing dust from escaping.

[0026] In a preferred embodiment, the stirring blade 16 is provided with a material-crushing blade 17 to improve the stirring and material-crushing efficiency.

[0027] In a preferred solution, the plurality of stirring blades 16 in each adjacent group of the plurality of stirring blades 16 are arranged in a staggered manner, thereby improving the stirring quality of the crushed materials and being highly practical.

[0028] In the preferred solution, the inner diameter of the pipe opening at the acceleration section 6 on the guide pipe 4 is smaller than the pipe opening diameter at other positions of the guide pipe 4. Reducing the pipe opening diameter accelerates the air flow speed and improves the negative pressure traction force at the connection between the unloading connecting pipe 8 and the guide pipe 4, which is convenient for traction of materials and strengthens the feeding force.

[0029] In the preferred solution, both ends of the acceleration section 6 on the guide tube 4 are connected to the guide tube 4 through the transition section 7. The acceleration section 6 and the guide tube 4 are smoothly connected, so that the inner wall of the tube is smooth and free of bumps, and the material is prevented from being stuck during pneumatic feeding.

[0030] The method of using the utility model is as follows: when in use, the air pump 1 and the motor 13 are started, and when the airflow passes through the acceleration section 6, the diameter of the pipe mouth is reduced, the airflow speed is increased, and the negative pressure traction force at the connection between the unloading connecting pipe 8 and the guide pipe 4 is increased, which is convenient for traction of materials and strengthens the feeding force. At the same time, the stirring blades 16 on the rotating shaft 14 can not only drive the air flow but also stir the crushed materials during the rotation process, break up the compacted or bonded material blocks, reduce the burden of pneumatic conveying, and make the conveying process more stable.

[0031] The beneficial effects of the utility model are as follows: pneumatic conveying is coordinated with negative pressure drainage, which drives the dust material to quickly enter the conveying structure for continuous feeding and tilting; when the negative pressure pulls the dust material, the mixing and crushing are coordinated to break up the compacted or adhered material blocks, reducing the burden of pneumatic conveying and making the conveying process more stable; the overall structure of the device is simple and reasonable, flexible to be assembled and used, and highly practical.
