Technical Field

[0001] This utility model relates to the field of column screw conveyor technology, specifically to an anti-chain plate tooth skipping mechanism for column screw conveyors. Background Technology

[0002] A screw conveyor is an essential piece of machinery in modern production and logistics. Its widespread application is significant in reducing heavy manual labor, improving labor productivity, and achieving mechanization and automation in material handling. The vertical screw conveyor is a type of screw conveyor that employs a vertical, multi-screw working structure. Due to its vertical conveying characteristics, it occupies less space compared to other conveying equipment, making it particularly suitable for environments with limited space.

[0003] Because the column screw conveyor adopts a multi-spiral conveying working structure, the conveyor belt in the middle has a large working stroke. In addition, the screw conveying part of the traditional column screw conveyor only relies on the frame structure for guidance and support. The transmission distance between the conveyor belt in the middle and the drive end is large and the driving tension is limited. When conveying heavy loads, the conveyor chain plate is prone to tooth skipping, which seriously affects the conveying operation of the screw conveyor. Therefore, an anti-tooth skipping mechanism for the column screw conveyor is proposed. Utility Model Content
