It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0022] Referring to Figures 1-5 The utility model aims at providing a kind of powder spiral feeding device not prone to blockage, including motor 1, the one end of motor 1 is fixedly connected with conveying shell 3, the output of motor 1 is fixedly connected with auger 30 of sleeve connection in the inside of conveying shell 3, motor 1 can drive auger 30 to rotate.

[0023] Conveying shell 3 is fixedly connected with inlet pipe 31 and discharge pipe 32, specifically, inlet pipe 31 is arranged at the top of conveying shell 3. Powder or other materials can enter the inside of conveying shell 3 through inlet pipe 31. Discharge pipe 32 is arranged at the bottom of conveying shell 3, and discharge pipe 32 is vertically downward, which can pour down the material rotated by auger 30 and discharge powder material.

[0024] The one end of inlet pipe 31 and discharge pipe 32 away from conveying shell 3 is fixedly connected with switching plate valve, and the one end of inlet pipe 31 and discharge pipe 32 away from conveying shell 3 is fixedly connected with first switching plate valve 401 and second switching plate valve 402 respectively. One side of inlet pipe 31 is fixedly connected with air inlet 33. Air inlet 33 is connected with external fan through pipeline.

[0027] Preferably, the end of the feeding pipe 31 away from the conveying shell 3 is fixedly connected with a first connecting port 5 through a switching plate valve, and the first connecting port 5 can be installed with a hopper or other material feeding device.

[0028] Preferably, the tail seat 6 is fixedly connected with a connecting flange 7. The tail seat 6 can be fixedly connected with a pipe through the connecting flange 7, and the pipe is connected with an external dust removal device, so that the continuously blown accumulated powder gas can be dust removal and recycled, air pollution is prevented, and the powder is recycled and reused.

[0029] Preferably, the switching plate valve comprises a fixed seat 41 and a switching plate 44 installed on the fixed seat 41 through a hinged shaft 43, and the two ends of the switching plate 44 are fixedly connected with a blocking plate 441 and a through plate 442 matched with the fixed seat 41, respectively. The switching plate 44 can rotate on the fixed seat 41, so as to switch the blocking plate 441 and the through plate 442. When the blocking plate 441 is rotated to be located inside the fixed seat 41, the switching plate valve is blocked, and neither material nor air can pass through the switching plate valve.
