Description

Technical Field

[0001] The invention relates to multi-spiral bin clearing equipment, belonging to the technical field of spiral bin clearing equipment. Background Art

[0002] Generally, the discharge port of a cylindrical storage silo is set at the bottom of the silo. When the discharge port is opened, the material above the discharge port will flow out along the discharge port under the action of gravity; while a large amount of material will remain in other parts of the bottom of the silo. The spiral silo cleaning machine is a kind of equipment used to clean up the remaining grain after the grain flows out of the cylindrical silo.

[0003] According to GB17440 "Dust Explosion Safety Regulations for Grain Processing, Storage and Transportation Systems", the silo belongs to the dust explosion-proof zone 20 environment, so the electrical equipment in the silo must meet the relevant requirements of the dust explosion-proof zone 20 environment. At present, most of the motors of conventional spiral bin cleaning machines on the market are installed in the silo, and according to the standard requirements, dust explosion-proof zone 20 motors should be used. However, there are no dust explosion-proof zone 20 motor products domestically and internationally, so the on-site warehouses are all using dust explosion-proof zone 21 motors, which poses certain safety hazards.

[0004] In view of the above technical problems, after searching, a Chinese patent with announcement number CN211366256U discloses a spiral bin cleaning machine, the technical key points of which are: including a circular track, a frame, a self-rotation power device, a spiral conveying device, and a revolution power device. Among them, the frame is located at the center of the circular track, and a silo is provided on the frame; the self-rotation power device includes a main motor and a transmission assembly, the main motor is arranged on the frame and located outside the silo, the transmission assembly is connected to the output shaft of the main motor, and the transmission assembly is rotatably arranged in the silo; the spiral conveying device is arranged on the frame, one end of the spiral conveying device is connected to the transmission assembly and communicated with the silo, when the main motor is working, the transmission assembly can drive the spiral conveying device to rotate; the revolution power device includes an air motor and a matching part arranged on the spiral conveying device, the matching part is connected to the air motor in a transmission manner and matched with the circular track. With such a configuration, the spiral bin cleaning machine meets the explosion-proof requirements of dust explosion-proof environments and avoids safety hazards.

[0005] However, the spiral bin cleaning machine in the aforementioned scheme has only a spiral shaft set at the front end of the equipment's orbital operation. Combined with the characteristics of the bin cleaning machine that cleans materials exposedly, when the remaining grain after the mainstream of the material in the cylindrical silo is compacted, the compacted material often collapses and buries the equipment during the cleaning operation of the spiral bin cleaning machine. After the equipment is buried, the load on the spiral shaft will increase, causing the main motor that drives the spiral shaft to rotate to stop for protection and unable to start under heavy load; at the same time, the collapsed material passes over the trough and collapses behind the trough, making it impossible for the equipment to unload the spiral shaft load by retreating and start again. It is often necessary to manually clean the collapsed material at the rear. After the equipment is retreated to unload the spiral shaft load, try to start the equipment again to continue the bin cleaning operation, which leads to low bin cleaning efficiency of the bin cleaning machine and certain personal safety hazards.

[0006] In response to the above technical problems, a Chinese patent with announcement number CN208948415U discloses a warehouse cleaning device, the technical key points of which are: it includes a frame and a rotating centering device, the rotating centering device is arranged at the end of the frame, and the frame is also provided with a conveying device for conveying materials and a driving device for controlling the movement of the frame; the conveying device includes a first auger and a second auger, and the first auger and the second auger are respectively arranged on the front and rear sides of the frame. During the warehouse cleaning process, if the compacted material collapses and buries the device, causing the first auger to fail to work normally or fail to start under load, the staff can start the second auger so that the second auger can clean the materials behind the warehouse cleaning device, so that the warehouse cleaning device can unload the load on the first auger by retreating, so that the first auger can resume working state, thereby improving the warehouse cleaning efficiency of the device.

[0007] In the above scheme, the first auger and the second auger are provided to solve the problem that the device cannot work normally after being buried by materials. However, the augers currently used are all cylindrical spirals, and there is only linear contact between their working space and the ground, which results in a large amount of material remaining in the area swept by the conveying device, and the material conveying efficiency is low.

[0008] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

On the other hand, the material-push rods rotate to send the materials on both sides of the conveying device into the conveying augers, which greatly improves the material conveying efficiency.

[0032] 5. By arranging a cleaning auger in the protective box, extending one side of the cleaning auger into the guide rail, when the revolution motor is started, the two cleaning augers are driven by the third transmission shaft to rotate while moving along the annular guide rail. During the rotation of the cleaning auger, the material between the fixed columns can be cleared out to prevent the travel gear from stopping due to material jamming.

[0052] By respectively arranging the material-push rod 11 on both sides of the two conveying augers 10, on the one hand, during the revolution of the conveying device, the material-push rod 11 rotates and drives the push teeth 24 to rotate. After the push teeth 24 are inserted into the material, traction force can be generated on the conveying device, so that the conveying device is not prone to overload and stop during the revolution. On the other hand, the material-push rod 11 rotates to send the material on both sides of the conveying device into the conveying augers 10, which greatly improves the material conveying efficiency.

[0056] The material shifting rod 11 includes a second transmission shaft 23 and a plurality of shifting teeth 24 evenly distributed on the second transmission shaft 23.
