[0033] During feeding, the material enters through the hopper at the top of the feeding guide 1 and falls into the screw conveyor 4 through the feeding port.

[0034] During the feeding process, when the material particles are large, they will accumulate in the spiral conveyor 4 below the feeding port, causing the feeding port to be blocked and affecting the feeding. At this time, the drive component 2 is started, driving the unblocking component 3 to reciprocate and unblock the material particles blocked below the feeding port.

[0035] This invention uses the drive component 2 and the unblocking component 3 to work together to act on the material particles accumulated in the spiral conveyor device 4 below the discharge port in a reciprocating motion. It can achieve automatic unblocking without much manual intervention. Not only is the unblocking effect significant and can effectively prevent material particles from blocking the discharge port, but the unblocking efficiency is also very high, which can effectively ensure production efficiency.

[0036] Example 2:

[0037] Example 2 is based on the example:

[0038] like Figures 1 to 3 As shown, the drive component 2 is set as a lifting component 21, which is fixedly installed on the outer wall of the discharge conduit 1. The lifting end of the lifting component 21 is connected to the unblocking component 3.

[0039] When clearing material particles, the lifting component 21 is activated, driving the clearing component 3 to move up and down reciprocally.

[0040] The lifting component is configured as a telescopic component. Optionally, the telescopic component is a hydraulic telescopic component, an electric telescopic component, or a pneumatic telescopic component. Preferably, a cylinder is used. The cylinder is detachably connected to the outer wall of the discharge guide tube 1 via threaded fasteners.

[0041] As an optional implementation, the unclogging component 3 is configured as an unclogging shovel, and a guide port is provided on the housing of the screw conveyor 4 on one side of the discharge port. The unclogging shovel passes through the guide port and is built into the screw conveyor 4, and the unclogging shovel slides in cooperation with the guide port.

[0042] The guide hole has a guiding effect, and can further limit the moving track of the dredging shovel, so that the reciprocating action of the dredging member 3 is more stable.

[0043] As an optional embodiment, the dredging shovel comprises a mounting section 31 and a vertical guide section 32, which are integrally arranged.

[0044] The mounting section 31 is horizontally arranged and connected with the lifting end of the lifting assembly 21, and the vertical guide section 32 is vertically arranged and connected with the top end of the mounting section 31.

[0054] As an optional embodiment, the dredging block 332 is provided with an inclined material guiding surface 3322 towards one side of the blanking port.
