[0020] The following will clearly and completely describe the present utility model with reference to the drawings and embodiments:

[0021] As Figures 1 to 4 shown, a kind of blanking pipe with a cleaning mechanism of the present utility model includes a pipe body 1. The cross-section of the pipe body 1 is square. The pipe body 1 includes a main channel 1-1 at the top for receiving materials conveyed in the previous process, and diversion channels 1-2 on both sides for diverting and conveying the received materials; Motors 2 are provided at the bottom of each diversion channel 1-2, and cleaning blades 3 are provided on the rotating shafts of the motors 2. The cleaning blades 3 are located inside the diversion channels 1-2; When feeding, the motors 2 are started to drive the cleaning blades 3 to rotate, completing the cleaning of the inner bottom wall of the diversion channels 1-2, avoiding the adhesion and accumulation of materials in the diversion channels 1-2, and ensuring the smooth falling of materials. The number of cleaning blades 3 provided on each diversion channel 1-2 is flexibly adapted according to the length of the diversion channel 1-2.

[0022] Furthermore, an installation opening 4 is provided at the bottom of the shunt channel 1-2, and an installation plate 5 is provided at the end of the motor 2. The motor 2 and the cleaning blade 3 are distributed on both sides of the installation plate 5, and the installation plate 5 is detachably connected to the bottom of the shunt channel 1-2. After the installation plate 5 is installed at the installation opening 4, its end face is flush with the inner bottom surface of the shunt channel 1-2 to ensure that the material smoothly falls along the bottom surface of the shunt channel 1-2.

[0023] Furthermore, a fixed pressing plate 6 is rotatably arranged at the bottom of the shunt channel 1-2 outside the installation opening 4. At least two fixed pressing plates 6 are symmetrically arranged. If the size of the shunt channel 1-2 is large and the size of the installation plate 5 is proportionally large, two groups of 4 fixed pressing plates 6 can be symmetrically arranged according to the actual situation to complete the fixing operation of the installation plate 5; an adjusting screw 7 is arranged at the end of the fixed pressing plate 6, and a pressing block 8 is movably connected to the end of the adjusting screw 7. After the installation plate 5 is installed at the installation opening 4, rotate the fixed pressing plate 6 to make it switch to the position of the fixed pressing plate 6, and then rotate the adjusting screw 7 to control the pressing block 8 to press the installation plate 5, so as to realize the fixing of the installation plate 5. The operation is simple and fast. It avoids the phenomenon of screw thread slipping caused by frequent disassembly during maintenance due to the use of screws for fixing.

[0024] Furthermore, one end of the fixed pressing plate 6 away from the pressing block 8 extends downward, and its bottom is rotatably connected to a fixed seat 9. The fixed seat 9 is fixedly arranged at the bottom of the shunt channel 1-2. A through hole is formed through the end of the fixed pressing plate 6 connected to the fixed seat 9. A positioning rod 11 is elastically arranged in the through hole through a spring 10, and the top end of the positioning rod 11 extends upward from the through hole. In the initial state, the top end of the positioning rod 11 is higher than the top end of the fixed pressing plate 6 for convenient manual adjustment operation; a positioning sleeve 12 is arranged at the bottom of the positioning rod 11, and positioning teeth 13 that mesh with each other are arranged on the end face of the positioning sleeve 12 opposite to the fixed seat 9. In the initial state, the positioning sleeve 12 and the fixed seat 9 are meshed through the positioning teeth 13 to ensure the stability of the fixed pressing plate 6 after the position is adjusted. When the position of the fixed pressing plate 6 needs to be adjusted, pull up the positioning rod 11 to drive the positioning sleeve 12 to move upward and disengage from the engagement with the fixed seat 9. At this time, rotate the fixed pressing plate 6. After the adjustment is in place, release the positioning rod 11, and the positioning rod 11 automatically resets under the restoring force of the spring 10 to complete the engagement with the fixed seat 9, realizing the positioning of the fixed pressing plate 6 and ensuring the stability of the fixed pressing plate 6 in the working state.

[0025] Furthermore, a limiting rod 14 is arranged on the pressing block 8, and the limiting rod 14 movably penetrates through the fixed pressing plate 6 to provide a limit when rotating the adjusting screw 7, ensuring that the pressing block 8 only moves along the direction of adjustment of the adjusting screw 7. In addition, the horizontal length of the pressing block 8 is preferably greater than the horizontal length of the fixed pressing plate 6 to increase the contact area with the installation plate 5. At the same time, a rubber gasket 15 is also arranged at the bottom of the fixed pressing plate 6 to ensure the tightness of the connection between the installation plate 5 and the shunt channel 1-2.

[0026] In this utility model, by arranging a cleaning blade 3 driven by a motor 2 at the bottom of the diversion channel 1-2, the continuous cleaning of the bottom of the diversion channel 1-2 can be completed through the rotation of the cleaning blade 3 during the blanking process, avoiding the accumulation and adhesion of materials, ensuring the smoothness of blanking, with a simple structure, convenient operation and strong practicability; through the optimization of the installation structure, the convenience of installation and disassembly is improved, facilitating subsequent maintenance and repair, with a simple structure, convenient operation and strong practicability.
