[0041] As a preferred embodiment, the clamping plate 63 is arc-shaped and gradually tapered from the two sides close to the one end of the rotating shaft 61 to the other end. By designing the clamping plate 63 in the above shape, the clamping plate 63 and the locking rod 13 do not interfere with each other during the downward overturning of the carriage 20, so that the clamping plate 63 can be quickly clamped on the locking rod 13.

[0042] In specific use, the push rod 62 is pushed upward, the rotating shaft 61 is rotated upward, the clamping plate 63 is rotated upward, the clamping groove 631 is separated from the locking rod 13, the push rod 62 is continuously pushed upward, the carriage 20 is overturned upward to an inclined unloading state, and unloading can be performed at this time. After unloading is completed, the push rod 62 is pulled downward, the carriage 20 is overturned downward, the rotating shaft 61 is rotated downward, the clamping plate 63 is rotated downward, the clamping groove 631 is reset and clamped on the locking rod 13, and the locking of the carriage 20 and the compartment frame 10 is realized. Through the overturning opening and closing mechanism 60 of the purely mechanical structure, the overturning and locking of the carriage 20 can be quickly realized without consuming power, the structure is simple, easy to operate, and low in cost.

[0043] In the embodiment, reference is made to Figure 1 The bottom two sides of the carriage 20 are hinged to the rear two sides of the compartment frame 10 and can be connected to the compartment frame 10 through the locking pull rod 30, so that the connection between the carriage 20 and the compartment frame 10 is more stable during overturning, and the opening and closing of the carriage door 21 of the carriage 20 is realized through the purely mechanical locking pull rod 30.

[0044] Specifically, reference is made to Figure 4 The locking pull rod 30 is provided with two, which are located at the bottom two sides of the carriage 20 and include a rod body 31. One end of the rod body 31 is hinged with a hook 32, the bending part of the hook 32 is hinged to the bottom of the carriage 20, and the hook 32 is used for hooking with the limiting block 11 outside the compartment frame 10.
