Description
Technical Field
[0001] The utility model relates to the technical field of material guide trough lifting, in particular to a material guide trough tail lifting device. Background Art
[0002] As an environmentally friendly continuous conveying equipment for bulk materials, belt conveyors are increasingly used in the field of bulk material transportation. During material transportation, when the unloading point of a special transfer station is located at the node of an uphill or downhill slope, the traditional guide trough is seriously blocked during use at the unloading point, and even causes damage to the equipment and cannot be used. A utility model of an automatic lifting guide trough device is indispensable. The traditional guide trough is fixed on the middle frame on both sides of the belt conveyor and is fixed in position after installation. When this special transfer point is not in use, the guide trough is located at the material conveying slope change point. When other transfer points of the belt conveyor convey material through this unloading point, this guide trough is seriously blocked due to its location. If the problem is not solved, the blocking phenomenon will be serious, and the traditional guide trough will be damaged by the continuous impact of the material and the lower part will be damaged, which will definitely make it unusable and scrapped.
[0003] Patent CN220683638U proposes an automatic lifting material guide trough device, which consists of a lifting frame consisting of a top arc-shaped support and a center column connected to the left and right sides of the arc support. A guide device connected to the material guide trough is slidably connected on the center column of the lifting frame. The material guide trough moves up and down along the center column driven by the guide device. It uses a cylinder as the output power of the guide device to ensure the stable lifting and lowering of the material guide trough in a flat surface.
