There are deep hoppers, shallow round bottom hoppers, and pointed hoppers. The hopper is another important part of the swing feeder. Its function is to store and transport materials. For the convenience of use, a pre-grinding hopper that is easy to clean is often used.

[0003] According to the description of a hopper that is easy to clean disclosed on the patent website (authorization announcement number: CN220077351U), "The utility model discloses a hopper that is easy to clean, including a base, a first adjusting rod is fixedly connected to the right side of the rear side of the top of the base, a second adjusting rod is fixedly connected to the left side of the rear side of the top of the base, the left side of the first adjusting rod and the right side of the second adjusting rod are both fixedly connected with a clamping block, a hopper body is fixedly connected between the two clamping blocks, a drying mechanism is provided on the front side of the hopper body, a first motor is fixedly connected to the top of the first adjusting rod, and a first threaded rod is fixedly connected to the output end of the first motor. The utility model solves the problems of poor cleaning effect and inability to dry the existing hopper by providing a base, a first adjusting rod, a second adjusting rod, a clamping block, a hopper body, a drying mechanism, a first motor, a first threaded rod, a first threaded block, a top cover, a lifting block, a second motor, a rotating rod, a stirring rod, a cleaning block, a water tank, a water pump, a nozzle and a supporting leg for coordinated use."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can solve the problems of poor cleaning effect and inability to dry the hopper in the existing hopper through the coordinated use of the arranged base, first adjusting rod, second adjusting rod, clamping block, hopper body, drying mechanism, first motor, first threaded rod, first threaded block, top cover, lifting block, second motor, rotating rod, stirring rod, cleaning block, water tank, water pump, nozzle and supporting legs. However, in actual application, since the position of the cleaning block of the device is relatively fixed, it is difficult to dynamically change the position of the cleaning block according to hoppers of different diameters so as to clean the inner wall of the hopper in different areas. As the cleaning work proceeds, when the cleaning effect of the cleaning block is reduced, it is difficult to quickly install and disassemble the cleaning block, resulting in poor practicality. Therefore, we urgently need a pre-grinding hopper that is easy to clean to solve the above problems. Utility Model Content
