The circular plate 6 is rotatably connected to the bracket, and the bottom end of the bracket is fixedly connected to the base 8. A first driving mechanism is fixedly installed on the base 8, and the first driving mechanism is transmission-connected to the semicircular shell 101 located below. The first driving mechanism drives the semicircular shell 101 located below to move upward, so that the semicircular shell 101 below is abutted against the semicircular shell 101 above, thereby realizing the buckling of the two semicircular shells 101, and a second driving mechanism is fixedly installed on the base 8, and the second driving mechanism is used to drive the circular plate 6 to rotate. The working principle and advantages of the present invention are as follows: during normal use, the material is put into the feed pipe 4 and enters the inner cavity of the conveying shell 1, and the reduction motor 7 is started to drive the rotating shaft 2 and the spiral blade 3 to rotate. The spiral blade 3 rotates to push the material to be conveyed and discharged from the discharge pipe 5; when the internal structure of the conveying shell 1 needs to be inspected, the reduction motor 7 is stopped, and the first driving mechanism is started to drive the lower semicircular shell 101 to move downward, exposing the internal structure of the semicircular shell 101 to the outside world, and then the second driving mechanism is started to drive the circular plate 6 to rotate, and the circular plate 6 drives the upper semicircular shell 101, the rotating shaft 2 and the spiral blade 3 to rotate, and the above structure is rotated to a suitable angle, which is convenient for the staff to inspect the internal structure of the semicircular shell 101.

By providing the first sealing strip 15, when the electric telescopic rod 9 drives the lower semicircular shell 101 to abut against the upper semicircular shell 10, the sealing between the lower semicircular shell 101 and the upper semicircular shell 101 is enhanced. By providing the second sealing strip 16, the sealing between the two ends of the lower semicircular shell 101 and the circular plate 6 is enhanced.

[0025] Specifically, the upper end of the feed pipe 4 is fixedly connected to a feed hopper 17, and two crushing rollers 18 are connected to the feed hopper 17 for rotation side by side. The rotating rod 19 of the crushing roller 18 passes through the side wall of the feed hopper 17 and is rotatably connected to the side wall of the feed hopper 17.
