Working method of tail car receiving hopper of bucket wheel machine

Abstract

The invention discloses a working method of a tail car receiving hopper of a bucket wheel machine. The device is composed of the receiving hopper, 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 rotation driving device and a material blocking cover support. The receiving hopper hydraulic lifting driving device is arranged on the receiving hopper support and drives the receiving hopper to achieve lifting motion; and the rotatable material blocking cover is of an arc-shaped structure, and an opening of the rotatable material blocking cover is smaller than the width of a tail car conveying belt. According to the working method, through the method that the receiving hopper can do lifting motion, the distance between the bottom end of the receiving hopper and the tail car conveying belt is actively increased or decreased, bulk materials cannot be blocked and accumulated at the bottom end of the receiving hopper, the bulk material conveying efficiency is improved, and abrasion of the tail car conveying belt is reduced. In addition, through the method that the material blocking cover can rotate, the opening of the material blocking cover faces the car coming direction of the tail car conveying belt all the time, the leakage preventing capability of the receiving hopper during multi-direction car coming of the tail car conveying belt is improved, and meanwhile flying dust pollution is reduced.

Description

technical field [0001] The invention relates to the field of large-scale bulk material excavation and conveying machinery, in particular to a working method of 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 t...

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. During the actual working process of bucket wheel machine reclaiming, the coming 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 bulk material prevention when the multi-directional tail car conveyor belt comes over.
