In addition, in fig. 3, the push plate assembly 2 is located at the front side of the carriage body 3, that is, the push plate assembly 2 is located at the initial position, and at this time, the push plate assembly 2, the bottom plate 31, the two side plates 33 and the rear plate 32 enclose the whole loading space, so that materials can be loaded in the loading space; in fig. 2, a state that the horizontal pushing component 5 drives the push plate assembly 2 to move to a certain position in the middle of the loading space is shown, and at the moment, part of materials can flow out of the discharge opening under the pushing action of the push plate assembly 2; in fig. 4, the push plate assembly 2 is positioned at the rear side of the carriage body 3, that is, the push plate assembly 2 is positioned at the end position, and a state in which the horizontal pushing assembly 5 drives the push plate assembly 2 to push out the material from the loading space is shown, and the push plate assembly 2 is positioned near the rear plate 32.

In one embodiment of the present utility model, the bottom plate 31 and the two side plates 33 are integrally formed or detachably formed.

It should be noted that, if the bottom plate 31 and the two side plates 33 are integrally formed, in other words, the bottom plate 31 and the left and right side plates 33 are integrally formed by bending a steel plate with a certain thickness, so that no welding point or bolt connection point is formed between the bottom plate 31 and the two side plates 33, thereby effectively enhancing the mechanical strength of the cabin body 3 and correspondingly prolonging the service life of the cabin body 3.

If the bottom plate 31 and the two side plates 33 are in a detachable structure, in other words, the bottom plate 31 and the left and right side plates 33 are detachably connected by plugging, bolting, etc., wherein the plugging mode is specifically that a plurality of plugs are arranged at the bottoms of the side plates 33, a plurality of slots are arranged on the bottom plate 31, and the side plates 33 are inserted into the slots through the plugs so as to be mounted on the bottom plate 31; the bolt connection mode is specifically that bolt holes are formed in bottoms of the bottom plate 31 and the side plate 33, the side plate 33 is arranged on the bottom plate 31 in a penetrating mode through fasteners such as bolts, and the bolt holes in the side plate 33 and the bottom plate 31 are used for being installed on the bottom plate 31, so that when the bottom plate 31 or a certain side plate 33 is deformed, damaged and the like to affect normal use, the corresponding bottom plate 31 and the side plate 33 can be used again only by replacing, and therefore maintenance cost is effectively reduced.

In one embodiment of the present utility model, as shown in connection with fig. 2 and 6, the push plate assembly 2 includes a push plate 21, and the push end of the horizontal push member 5 is connected to the push plate 21.
