Anti-blocking U-shaped spiral feeding machine

Abstract

The invention relates to the technical field of spiral feeding machines, and discloses an anti-blocking U-shaped spiral feeding machine which comprises a main body support, a conveying pipe is fixedly connected to the interior of the main body support, a driving main shaft is rotatably connected to the interior of the conveying pipe in a penetrating mode, spiral blades are fixedly connected to the surface of the driving main shaft, and a discharging pipe fixedly communicates with the bottom of the conveying pipe. The top of the main body bracket is fixedly connected with a storage box, and the bottom of the storage box is fixedly communicated with a feeding pipe; materials accumulated in the material storage box become loose through continuous rotation of the stirring frame in the material storage box, then the materials in the material storage box are evenly distributed, meanwhile, when a feeding pipe is seriously blocked, a knocking block can knock the feeding pipe in a reciprocating mode to enable the feeding pipe to vibrate, and under the action of vibration, the materials in the material storage box are evenly distributed. When the feeding pipe is blocked, materials accumulated in the feeding pipe can displace, the blocked materials are loosened and flow again, and the situation that the machining process is delayed due to continuous blocking of the feeding pipe is avoided.
