[0028] Working principle: By starting the cylinder 5 on the carrying plate 4, the cylinder 5 can drive the connecting rod 20 to move up and down reciprocatingly, so that the movable connecting rod 20 drives the movable plate 6 to move up and down reciprocatingly in contact with the inner wall of the conical lower material bin 2, so as to scrape off the material adhering to the inner wall of the conical lower material bin 2. At the same time, under the action of the upper limit block 7 and the lower limit block 8, the movable plate 6 is prevented from being offset due to material filling during the movement. By pushing the slider 12, the movable slider 12 drives the T-block 11, the rotating rod 13, the U-bar 14 and the positioning block 15 to move at the same time. When the movable T-block 11 moves horizontally on the limit rod 10, it can squeeze the inner wall of the T-slot 17 The spring 18 is in a taut state. When the movable positioning block 15 is separated from the fixed block 16, the fixation and connection between the straight section lower bin 1 and the cone lower bin 2 are released. At the same time, the restriction on the torsion spring 19 is released, so that the torsion spring 19 is turned over and stretched, so that the turned over torsion spring 19 can drive the rotating rod 13 to rotate, and then the rotating rotating rod 13 can drive the U-shaped rod 14 and the positioning block 15 to rotate with the rotating rod 13 as the central axis, so that the rotated positioning block 15 will not affect the subsequent connection between the straight section lower bin 1 and the cone lower bin 2. Then release the pushed slider 12, so that the spring 18 is no longer restricted to rebound, so that the rebound spring 18 drives the T-block 11, the slider 12, and the rotating rod 1 3. The U-shaped rod 14 and the positioning block 15 are reset and moved, and then the straight section lower silo 1 and the cone lower silo 2 can be separated, so that the inner walls of the straight section lower silo 1 and the cone lower silo 2 can be cleaned. When installing the straight section lower silo 1 and the cone lower silo 2, the straight section lower silo 1 is placed on the cone lower silo 2, and the outer surface of the straight section lower silo 1 is respectively in contact with the four connecting blocks 3, so that the straight section lower silo 1 is restricted, and the fixed block 16 on the straight section lower silo 1 can correspond to the positioning block 15, and then the slider 12 is pushed, so that the moving slider 12 simultaneously drives the T-block 11, the rotating rod 13, the U-shaped rod 14 and the positioning block 15 to move, so that the moving T-block 11 squeezes the spring 18 on the T-slot 17, so that the spring The spring 18 is in a taut state.
