Tail vehicle receiving hopper of bucket wheel machine

Abstract

The invention discloses a tail vehicle receiving hopper of a bucket wheel machine. The tail vehicle receiving hopper is composed of a receiving hopper body, a receiving hopper support, a receiving hopper hydraulic lifting device, a receiving hopper hydraulic lifting driving device, a rotatable material blocking cover, a material blocking cover rotating driving device and a material blocking cover support; lug plates on the two sides of the receiving hopper body are connected with the receiving hopper hydraulic lifting device fixed to the material blocking cover support to arrange the receiving hopper body on a tail vehicle conveying belt; the rotatable material blocking cover is in an arc shape; the rotatable material blocking cover, the material blocking cover support and the receiving hopper body are coaxially arranged from outside to inside; the lower section of the receiving hopper body is wrapped by the rotatable material blocking cover; a sliding rail on the outer wall of the rotatable material blocking cover is matched with a sliding groove in the inner wall of the material blocking cover support; the material blocking cover driving device drives the sliding rail to slide in the sliding groove to enable the material blocking cover to rotate; and a lifting hopper is matched with the rotatable material blocking cover, abrasion of the inner wall of the hopper and the tail vehicle conveying belt due to bulk material accumulation and blockage can be reduced, and the leakage preventing capacity is fully guaranteed while the tail vehicle receiving hopper adapts to multi-direction tail vehicle coming.

Description

technical field [0001] The invention relates to the field of large-scale bulk material excavation and conveying machinery, in particular to a tail car receiving hopper of a bucket wheel machine. Background technique [0002] Bucket wheel machine is a large-scale machine for continuous loading and unloading of bulk materials. It is mainly used in docks, large iron and steel plants, large-scale thermal power plants and mines, etc., to undertake storage, excavation and transportation of bulk materials. Because of its high efficiency and simple operation, it is widely used at home and abroad. The tail car receiving hopper is a very important part when the bucket wheel machine is performing material reclaiming operations. During the material reclaiming operation, the bulk material dug by the bucket wheel bucket falls on the tail car conveyor belt through the cantilever conveyor belt through the tail car receiving hopper Finally, the bulk material is stacked to the stock yard thr...

AI Technical Summary

Problems solved by technology

[0004] 1. In order to prevent the leakage of bulk materials and the air pollution caused by the dust, the tail car receiving hopper of the existing bucket wheel machine is often arranged in such a way that the distance between the bottom of the receiving hopper and the tail car conveying belt is small. The fixed arrangement of such a small distance leads to the fact that when the volume width in the bulk material is greater than the distance between the bottom end of the receiving hopper and the conveyor belt of the tail car, these bulky bulk materials will block and accumulate on the conveyor belt of the tail car. Between the conveyor belt and the inner wall of the receiving hopper in the conveying direction, the bulk material conveying efficiency will be reduced. At the same time, these clogged and accumulated larger bulk bulk materials will continue to roll and wear the tail car conveyor belt and the inner wall of the receiving hopper when the conveyor belt is running. , reducing equipment life and efficiency

[0005] 2. In order to overcome the problem of bulk material leakage and dust caused by the increase in the distance between the bottom of the hopper and the conveyor belt, the application number is CN201621178739.2, and the patent name is "a new type of bucket wheel guide groove structure". Disclosed is a material guide trough structure with baffle plates on both sides of the lower section of the receiving hopper, but the ability to prevent bulk material leakage is still lacking after only adding baffle plates on both sides of the lower section of the hopper

[0006] 3. In the actual working process of bucket wheel machine reclaiming, the incoming direction of the tail car conveyor belt is not fixed, and the structure of the guide groove with the addition of a baffle plate cannot guarantee the dispersion of two cars in the multi-directional tail car conveyor belt. Material leakage prevention ability
