Anti-blocking coal feed port

Abstract

The utility model belongs to the technical field of coal processing, and particularly relates to an anti-blocking coal feeding port which comprises a feeding hopper, a vibrating screen, a fixing plate, an air blowing device, a chute anti-blocking protection device and a baffle. When the vibrating screen is used, through the double-layer screen structure of the concave arc screen body on the vibrating screen and the gravity center principle, large-size materials fall into the center of the concave arc screen body due to vibration due to the fact that the diameter of a falling hole in the center is the largest, the materials are vibrated and conveyed, and meanwhile the materials are conveyed through wind source power. According to the feeding device, the small-size materials on the periphery rapidly fall onto the conveyor belt, then the large-size materials fall again, and therefore the materials can be evenly and smoothly added into the feeding port, and the situation that the feeding port is blocked is avoided.

The supporting frame 2011 and the connecting rods 2013 are both connected to the feed hopper 1.

[0028] Through the vibrating screen 2 provided above the feed hopper 1, under the action of the concave arc screen body 204 structure, the material is vibrated and screened and transported using the center of gravity principle. At the same time, with the use of the blowing device 4, the material can be evenly and smoothly added to the feed port, which has a good anti-blocking effect.

[0029] Please refer to Figure 1 and Figure 5 Air ducts 101 are provided inside the hopper 1 around the periphery, and a plurality of air blowing ports 102 are provided above the air ducts 101 .
