[0036] Working principle: during use, when it is necessary to collect the dust at the feeding station, by starting the fan 8, the fan 8 and the motor 9 are powered by an external power supply. At this time, the fan 8 drives the air circulation to generate a negative pressure between the collection box 5 and the collection frame 4. The inner wall of the collection frame 4 is provided with a plurality of suction ports. When the material is put into the storage tank 3 through the suction port, the dust scattered by the material is sucked into the collection frame 4, so that the dust enters the collection box 5, and the dust is intercepted by the sieve plate 6, so that the dust accumulates in the collection box 5. When the sieve plate 6 needs to be cleaned, by starting the motor 9, the rotation of the output shaft of the motor 9 can drive the transmission shaft 10 to rotate and drive the eccentric wheel 11 to rotate. The rotation of the eccentric wheel 11 can reciprocate the sieve plate 6. At this time, the sieve plate 6 vibrates to shake off the dust to prevent the sieve plate 6 from being blocked. When the sieve plate 6 needs to be replaced, first push the unlocking plate 16 to move left. When the unlocking plate 16 moves left, it will push the push rod 18. The unlocking plate 16 is released at this time, and the unlocking spring 17 pushes the unlocking plate 16 to reset and drives the rod 19 to move down and engage with the slot to fix the cross plate 12 so that the fixed block 13 remains fixed in the current position, thereby achieving the effect of replacing the sieve plate 6.
