[0021] The front side of the discharging square tube 6 is provided with the fourth shaft 11 rotatably connected on the side frame, the cam 12 is arranged on the fourth shaft 11 as a follower, the wheel surface of the cam 12 is tightly attached to the outer tube wall of the discharging square tube 6, the fourth shaft 11 is arranged below the third shaft 10, and the power assembly (not shown) for controlling rotation is rotatably connected on the fourth shaft 11, and the power assembly is arranged on the side frame 1.

[0022] Further, the width of the discharging square tube 6 is greater than the width of the discharging slope 2.

[0023] Further, the power assembly comprises a motor and a speed reducer.

[0024] In the embodiment, the front end of the discharging slope 2 is downwardly inclined in the natural state due to the forward center of gravity, so that the guide plate 5 is pressed on the guide wheel 9, and the top of the discharging square tube 6 swings back and the bottom swings forward due to the downward pressure on the guide wheel 9, so that the front side outer tube wall of the discharging square tube 6 continuously abuts against the cam 12. When the motor drives the fourth shaft 11 and the cam 12 thereon to rotate through the speed reducer, the discharging square tube 6 swings forward and backward due to the continuous abutment of the outer tube wall of the discharging square tube 6 against the cam 12 during rotation. At the same time, the discharging slope 2 swings up and down through the transmission of the guide plate 5 and the guide wheel 9, so that the materials falling on the discharging slope 2 can be smoothly discharged from the front end of the discharging end, fall into the discharging square tube 6, and finally be discharged from the discharging square tube 6.
