Tail material cleaning device for FU chain conveyor

Abstract

The invention discloses a tail material cleaning device for an FU chain conveyor. The tail material cleaning device comprises a material stop plate which is arranged in a casing and positioned behind a tail wheel, wherein the upper part of the material stop plate is a plane, and the lower part of the material stop plate is an arc-shaped surface; vertical support rib plates are respectively and fixedly connected to the two sides of the material stop plate, and steel angles are respectively and fixedly connected to the bottoms of the vertical support rib plates; an upper L-shaped horizontal support rib plate and a lower L-shaped horizontal support rib plate are respectively and fixedly connected to the back of the material stop plate; bolt holes in the back of the material stop plate and the two ends of the upper and lower L-shaped horizontal support rib plates are respectively and correspondingly penetrated by an upper bolt and a lower bolt from back to front; nuts are respectively bolted at the front ends of the upper and lower bolts; the rear ends of the upper and lower bolts are respectively sleeved by springs. The tail material cleaning device provided by the invention has the advantages that the effects of material accumulation at the tail of the conveyor on the tensioning effect of the tail wheel are eliminated, so that failures can be prevented; meanwhile, a tail empty segment can be shortened and even completely removed, so that the conveyor length is effectively reduced, the cost and operation power consumption of the whole conveyor are lowered, and the operational economy of the FU chain conveyor is improved.

Description

technical field [0001] The invention relates to the field of transportation machinery, in particular to a tail cleaning device of a FU chain conveyor. Background technique [0002] FU chain conveyor is a continuous conveying equipment for conveying bulk materials such as powder, small granule and small block, which are less abrasive and not easy to agglomerate, and can be conveyed horizontally and obliquely. The FU chain conveyor is composed of the bottom plate, side plate and cover plate of the casing to form a sealed shell. The bottom plate and the side plate form a conveying tank. When working, the material falls into the feed port on the top of the organic casing, and the conveyor chain is driven in the casing. The material flows from the tail to the head outlet to complete the conveying process. The conveying chain is driven by the head sprocket, and is redirected and tightened by the longitudinally movable tail sprocket. The tail casing reserves a space for the tai...

Problems solved by technology

In practical application, due to the fact that granular materials and powdery materials are scattered and sputtered when they fall from the feed inlet, if the feed inlet is arranged closer to the tail, the materials will easily flow into the tension space of the tail, which exceeds the working range of the conveyor chain. , the material cannot be discharged, and the continuous accumulation of material will block the tensioning space of the tail wheel, which will directly affect the operation of the conveyor chain.

In order to avoid such failures, when selecting and designing the current FU chain conveyor, it is necessary to set a certain length of space between the feed port and the tail wheel. According to different working conditions, the distance is set between 1000mm and 2000mm , this empty section does not participate in the actual transportation, it is only used to clean up the tail splashing and returning materials. Although the setting of this section reduces the occurrence of tail failures of the FU chain conveyor, it obviously increases the use cost of the equipment, and for the inclined state When conveying, it is still impossible to completely avoid the occurrence of material backflow and accumulation at the tail
