Description

Charging hopper Technical Field The utility model relates to the technical field of hoppers, in particular to a charging hopper. Background The hopper for loading and unloading materials generally comprises a cylindrical hopper body and a cover body hinged at the lower end of the hopper body, wherein a lock catch is clamped between the cover body and the hopper body through a lock tongue. When the hopper is filled with smaller materials such as aluminum blocks, if the gap between the lock tongue and the lock catch is larger, the cover body and the hopper are not tightly closed, the cover body shakes and gaps are formed between the cover body and the hopper, and then the aluminum blocks are easy to be clamped in the gaps or leak from the gaps, so that the production efficiency is affected. Therefore, it is desirable to design a loading hopper with less lid sloshing when closing the lid. It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art. Disclosure of utility model Aiming at the defects of the prior art, the embodiment of the utility model discloses a charging hopper, which aims to solve the problem that when a cover body is closed, a gap is generated between the cover body and the hopper, so that materials leak out and the production efficiency is affected. The technical scheme adopted by the utility model is as follows: The charging hopper comprises a hopper body, a cover body, a switch assembly and a sliding block, wherein the hopper body is of a hollow structure with an upper opening and a lower opening, the cover body is hinged to the lower end of the hopper body, a lock catch is arranged at the upper end of the cover body, the switch assembly comprises a rotating shaft and a gear, the rotating shaft can rotatably penetrate through the side face of the hopper body, the gear is fixed at one end of the rotating shaft, which is located in the hopper body, the sliding block is arranged on the inner wall of the hopper body in a sliding mode, the upper end of the sliding block is meshed with the gear, a lock tongue is arranged at one end, which is far away from the rotating shaft, the rotating shaft is rotated to drive the gear to rotate, the gear drives the sliding block to slide, and the lock tongue slides into or slides out of the lock catch to close or open the cover body.
