The raw material screening device for bamboo charcoal production comprises a screening machine, a supporting plate is fixedly connected to the bottom of the front side of the screening machine, a transmission groove is formed in the supporting plate, a first rotating wheel is arranged in the transmission groove, a mounting plate is fixedly connected to the left side of the inner wall of the screening machine, and a motor is fixedly connected to the top of the mounting plate; the output end of the motor is fixedly connected with a second rotating wheel, the first rotating wheel and the second rotating wheel are connected through a belt, the bottom of the first rotating wheel extends into the supporting plate and is movably connected with the inner wall of the supporting plate through a bearing, and the left side of the top of the first rotating wheel is fixedly connected with a traction rod; a moving frame located at the top of the first rotating wheel is slidably connected into the transmission groove, and a connecting block is fixedly connected to the top of the moving frame. The material frame can be effectively and uniformly shaken, the phenomenon that falling materials are accumulated on one side and easily overflow due to the fact that the position of the material frame is fixed is avoided, and the use performance of the screening machine is enhanced.

This utility model provides a tilting pneumatic lifting door structure for an operating platform, including a tilting pneumatic lifting door mounted on an operating platform. The tilting pneumatic lifting door includes a door panel assembly, a cylinder assembly, and a slide rail assembly. The slide rail assembly and the cylinder assembly are mounted on the operating platform. The door panel assembly is mounted on the slide rail assembly and connected to the output end of the cylinder assembly. This utility model has the following advantages: by using the door panel assembly, cylinder assembly, and slide rail assembly in combination, it solves the problems of easy shaking and unstable movement trajectory during lifting, resulting in stable and reliable operation with minimal shaking, smooth movement, and low noise. It also reduces the operating costs for workers. The lifting stroke is tilted at an 80-degree angle to the horizontal plane, improving the ergonomic and inconvenient operation problems of vertical lifting doors.
