[0034] The sliding plate 120 slides on the end face of the guide groove 210 away from the nested ring 220. A feeding channel connecting the hopper 110 and the slump bucket 300 is provided inside the sliding plate 120, the guide groove 210 and the nested ring 220. When feeding into the hopper 110, concrete will enter the slump bucket 300 along the feeding channel. After the feeding is completed, the sliding plate 120 is pushed to move the hopper 110 away from the guide groove 210 and the nested ring 220, and at the same time, the top end face of the slump bucket 300, that is, the end face of the slump bucket 300 away from the ground, is scraped flat.

[0035] In this embodiment, the hopper 110 and the sliding plate 120 are an integral structure, and the sliding plate 120 slides on the end surface of the guide plate assembly 200 away from the nesting ring 220. In actual operation, the hopper assembly 100 is placed on the guide plate assembly 200. The movable disassembly structure is mainly used to facilitate the disassembly and movement of the equipment. After the hopper 110 and the sliding plate 120 are removed, it is more convenient to clean the guide plate assembly 200, thereby reducing the occurrence of equipment jamming caused by concrete residues.
