In practical application, in theory, rubber or plastic and other materials which can seal a certain position and can be bent and deformed can be selected, but the service life and the efficiency of conveying grains are not ideal, so that the steel is better to be processed into specific mechanical parts.

The grain is transported from the front end of the fixed pipe 100 to the end of the movable pipe 200 in the positive direction of the grain transporting direction.

In this embodiment, the sealing cap 300 includes two parts, one of which is a fixed cap 310 provided at the distal end of the fixed pipe 100, and the other of which is a movable cap 320 provided at the front end of the movable pipe 200. The front end of the fixed cover 310 overlaps the front end of the movable cover 320, and the front end of the fixed cover 310 extends into the front end of the movable cover 320, with the overlapping portions being in clearance fit. In order to prevent the movable cover 320 from rotating relative to the fixed cover 310, the sections of the fixed cover 310 and the movable cover 320 are preferably arc-shaped, the outer diameter of the fixed cover 310 is equal to the inner diameter of the movable cover 320, the centers of circles of the fixed cover 310 and the movable cover 320 are coincident, the centers of circles of the same side of the fixed cover 310 and the movable cover 320 are respectively provided with a rotating shaft 330, and the movable cover 320 rotates around the rotating shaft 330.
