Description

Chute pushing device for conveying sticky materials

Technical field

The invention belongs to the technical field of material conveying and transfer equipment, and specifically relates to a chute pushing device for conveying viscous materials.

Background technique

Belt conveyors are often used for material transportation in China. Generally, the discharge end of the belt conveyor cooperates with the chute to realize the storage or transfer of materials. However, the chute has limitations for transporting viscous materials with high moisture content, especially for transporting viscous materials with high moisture content. This is mainly because moisture adheres to the surface of the material, making the material highly viscous. When the chute transfers and transports such materials, no matter how large the inclination of the chute is or what kind of anti-sticking device is installed, some materials will always adhere to the bottom and sides of the chute. As the transportation time increases, the bottom and sides of the chute will develop. Different degrees of hardening phenomenon prevent the materials from being transported out of the chute smoothly, causing the chute to be blocked. Therefore, it is necessary to research and develop devices that make the chute convey viscous materials more smoothly.
