Detailed Description
Example 1
As shown in fig. 1, the sealing feeding mechanism for the screw conveyor of the present invention is mainly modified with respect to the feeding pipeline 10 between the bin 70 and the screw conveyor 20. The pipe diameter of the feeding pipeline 10 is generally larger than the caliber of the feeding port of the screw conveyor 20, so the feeding pipeline 10 and the screw conveyor 20 are generally required to be provided with a tapered connector 11. When the material is sticky or damp, the material is easy to form arch on the conical connector 11.

The first sealing plate 31 is a gate valve. A first power mechanism 51 is arranged outside the feeding pipeline 10, and the first power mechanism 51 is an oil cylinder. The first power mechanism 51 pulls the first sealing plate 31 at a constant speed according to the feeding speed of the material or according to a constant time, and drops the material accumulated on the first sealing plate 31. When the materials stored in the first sealing plate 31 are completely fallen, the first sealing plate 31 is reset under the action of the first power mechanism 51, and the materials are stored continuously. In this way, the first sealing plate 31 is moved back and forth at regular intervals by the first power mechanism 51, so that the feeding pipeline 10 is opened or closed at intervals.
The lower part of the first sealing plate 31 is provided with a first horizontal toggle part 61, and the first horizontal toggle part 61 extends to the conical connector 11.
