The bearing housing 1221 is located at one end of the support body 121 facing the unloading unit 110 and has a bearing mounting hole. The bearing 1222 is vertically disposed in the bearing mounting hole. The unloading unit 110 is connected to the inner ring of the bearing 1222 through a first adjusting unit 130.

[0038] In practice, bearing housing 1221 is used to install bearing 1222; bearing 1222 can withstand radial load and axial downward load, that is, bearing 1222 and bearing housing 1221 can withstand the weight of unloading unit 110.

[0039] According to one embodiment of the present invention, the first adjustment unit 130 may include a rotation drive assembly 131 and a discharge unit support arm 132 (or discharge trough support).

That is, the output end of the motor 1311 is connected to the input end of the speed reducer 1312, and the output end of the speed reducer 1312 is connected to the rotating shaft 1322.

[0048] In a specific embodiment, the speed reducer 1312 can reduce the speed and increase the torque, i.e., the speed reducer 1312 can reduce the speed and increase the torque to drive the horizontal rotation of the discharging unit 110; the motor 1311 and the speed reducer 1312 only provide the torque and do not bear the gravity of the discharging unit 110.

[0049] According to an embodiment of the present application, the rotation driving assembly 131 can further comprise an encoder arranged on the motor 1311 and used to detect the horizontal rotation angle of the discharging unit 110.

[0050] In a specific embodiment, through the above structure, the horizontal rotation angle of the discharging unit 110 can be determined, and the specific angle value of the horizontal rotation angle of the discharging unit 110 can be accurately determined.
