Figure 3 As shown, a sliding plate 2.2 is slidably connected in each sliding groove 2.1, a mounting plate 2.3 is welded above each sliding plate 2.2, and the housing 1 is hingedly connected to one side of the mounting plate 2.3 via a hinge.

[0020] like Figure 2As shown, a lifting device 3 is arranged at the bottom of the box body 2, and the lifting device 3 includes two first driving members 3.1. The first driving member 3.1 is a hydraulic cylinder, a pneumatic cylinder or an electric push rod. In this embodiment, the first driving member 3.1 is a hydraulic cylinder. The two first driving members 3.1 are arranged horizontally opposite to each other. A movable plate 3.2 is welded on the driving rod of each first driving member 3.1. In order to make the movable plate 3.2 move better, a slide rail 3.5 is welded at the bottom of the box body 2. A guide groove is provided on the lower side of each movable plate 3.2, and the movable plate 3.2 slides on the slide rail 3.5 through the guide groove.

[0021] A hinged plate 3.3 is hinged on each movable plate 3.2, a support plate 3.4 is hinged above the two hinged plates 3.3, and the motor 4 is fixed above the support plate 3.4 by bolts. When the driving rods of the two first driving members 3.1 are extended, the support plate 3.4 can be moved upward, thereby driving the motor 4 to move upward.

[0022] The main shaft of the motor 4 passes through the upper side wall of the box body 2, and the main shaft of the motor 4 is connected to the drum through a clamping device. The clamping device includes a first clamping component 5.1, which is welded to the main shaft of the motor 4. A clearance groove 2.4 is provided above the box body 2, and the first clamping component 5.1 is arranged in the clearance groove 2.4. The first clamping component 5.1 is clamped and matched with the second clamping component 5.2, and the second clamping component 5.2 is connected to the bottom of the drum through a rotating shaft.
