Abstract

The invention discloses a hoist capable of assisting in sand screening, which comprises a machine body. A machine cavity with an opening to the left is arranged in the machine body. Fixed blocks are fixedly connected to the upper and lower inner walls of the machine cavity. The lifting chamber with the opening to the left, the lifting chamber is provided with a lifting mechanism, the front and rear inner walls of the lifting chamber are provided with a clamping chamber with an opening facing the inner wall of the center of the lifting chamber, and a protection mechanism is provided in the clamping chamber , the body is provided with a power chamber, the invention is simple in structure and convenient in operation. When the sand needs to be screened, the automatic sand screening can be completed through mechanical transmission. When the sand needs to be lifted to a high place, it can be realized through mechanical transmission. The sand is automatically lifted to a high place. When it is necessary to protect the sand during the process of lifting, the mechanical transmission can realize automatic deceleration, thereby reducing the workload of workers.
