[0030] Preferably, the screw conveyor 2 is a full-surface screw conveyor.

[0031] Preferably, the first motor 5 of the screw conveyor 2 is frequency conversion controlled. According to the flexible needs of actual production, the rotation speed of the first motor 5 of the screw conveyor 2 can be set to facilitate the control of the feeding speed of the materials.

The screw conveyor 2 is a variable-pitch screw conveyor with an increasing pitch, that is, the pitch of the conveying blades 6 on the first rotating shaft 4 of the screw conveyor 2 increases in sequence from the second blanking pipe 7 to the first blanking pipe 3. When the screw conveyor 2 is a variable-pitch screw conveyor with an increasing pitch, it can avoid mechanical extrusion of the material during the conveying process, loosen the material, and is more conducive to the stable material flow of the dispersion discharging device. The material is more likely to be evenly and continuously dispersed into the subsequent processing device, and the impact on the subsequent equipment during the discharging of the material can be avoided.

[0033] Preferably, the second motor 16 is frequency conversion controlled, and the rotation speed of the second motor 16 can be set according to the flexible needs of actual production.

[0034] Preferably, the third motor 22 is frequency conversion controlled, and the rotation speed of the third motor 22 can be set according to the flexible needs of actual production.

[0035] The first usage method of the present utility model: During the production of feed products, the discharge outlet of the feed bin can be connected to the feed inlet 23 at the upper part of the storage bin 8, so that the material discharged from the feed bin can enter the storage bin 8, and the feed material can be stored in the storage bin 8.

[0036] The second usage method of the present utility model: During the production of feed products, the discharge outlet of the feed equipment in the previous process can be connected to the feed inlet 23 at the upper part of the storage bin 8. The storage bin 8 serves as a bin, so that the material discharged from the feed equipment can enter the storage bin 8, and the feed material can be stored in the storage bin 8.

[0037] When it is necessary to use the present utility model to perform discharging treatment on the material, the third motor 22, the first motor 5, and the second motor 16 can be started in sequence. The dispersion frame 18 is driven by the third motor 22 to rotate, the first rotating shaft 4 is driven by the first motor 5 to rotate, and the second rotating shaft 9 is driven by the second motor 16 to rotate. The second rotating shaft 9 drives the dredging and discharging device provided thereon to perform dredging and discharging on the material inside the storage bin 8. The second rotating shaft 9 can drive the first stirring paddle 10, the second stirring paddle 11, and the third stirring paddle 12 to rotate, thereby performing dredging and discharging on the material inside the storage bin 8. When the first stirring paddle 10, the second stirring paddle 11, and the third stirring paddle 12 rotate, the obstacles hindering the flow and dispersion of the material are eliminated, making the flow and dispersion property of the material better, ensuring the good flow and dispersion property of the material. The material in the storage bin 8 can be evenly and smoothly fed to the discharge port at the lower part of the storage bin 8, so that the material enters the screw conveyor 2 through the second blanking pipe 7. Through the operation of the dredging and discharging device, the flow of the material can be accelerated during discharging, the flow and dispersion property of the material can be improved, and the feeding to the discharge port can be made evenly, preventing the material from being blocked during feeding.

[0038] When the first rotating shaft 4 of the screw conveyor 2 rotates, the conveying blade 6 rotates with the first rotating shaft 4, and the conveying blade 6 can convey and discharge the feed from the second blanking pipe 7 to the first blanking pipe 3.

[0039] Since a dispersion discharging device is arranged below the first blanking pipe 3 of the screw conveyor 2, the material discharged from the first blanking pipe 3 of the screw conveyor 2 can enter the dispersion discharging device. The material is discharged from the first blanking pipe 3 and enters the dispersion frame 18. When the dispersion frame 18 rotates, the material is evenly dispersed and laid flat in the dispersion frame 18. At the same time, the material will fall from the discharge holes on the bottom surface of the dispersion frame 18, stabilizing the material flow and facilitating the smooth, uniform and continuous dispersion of the material into the subsequent processing device of the dispersion frame 18, and avoiding the impact of the material discharge on the subsequent equipment.

[0040] By setting the dispersion discharging device, it is avoided to directly discharge the material from the discharge port, and it is convenient to evenly disperse the material into the subsequent processing device.
