Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, in particular to a non-powered material spreading and recovery belt conveyor. Background Art

[0002] Belt conveyor material spillage is one of the common faults of belt conveyors. It is easy to occur at the tail of the machine, the suspended part of the concave arc section of the belt, the transfer point, etc. The material spillage at the transfer point is mainly at the drop hopper, guide chute, etc. The tail of the machine is mainly caused by the backflow of materials at the transfer point. Especially for the belt with a large inclination angle, the backflow of materials is more serious, and a large amount of materials will be scattered on the ground under the tail of the machine. On the other hand, due to the impact of a large amount of materials in the drop chute on the belt, there is also material spillage on both sides of the belt. These materials fall to the ground, causing transportation losses and economic losses, and also increasing the amount of manual cleaning.

[0003] The belt conveyor falling material recovery device with publication number CN117302908A comprises a conveying device, a conveyor belt installed inside the conveying device, and a recovery and cleaning mechanism arranged below the conveyor belt. A feed port is arranged on the top of the conveying device and the feed port is located above one end of the conveyor belt. A motor is installed on the outer wall of the conveying device and the output end of the motor is connected to the shaft end of the conveyor belt. A discharge port is formed at the end of the conveying device and the recovery and cleaning mechanism and the ends of the conveyor belt both extend to the discharge port. The present invention installs a recovery and cleaning mechanism at the discharge port of the conveying device. The blowing mechanism in the recovery and cleaning mechanism can blow off the material attached to the belt and blow it toward the discharge port. Part of the material falls on the discharge belt.
