Crossheading bidirectional transporting, screening, crushing and transloading system

Abstract

The invention relates to a crossheading bidirectional transporting, screening, crushing and transloading system and relates to the technical field of transloading machines. The crossheading bidirectional transporting, screening, crushing and transloading system comprises a crushing device, a screening device and a bidirectional transporting device. The crushing device and the screening device arearranged a landing section and are connected. The screening device is a screening groove and comprises a screening middle plate and a screening bottom plate. The screening middle plate is located on the upper part of the screening bottom plate, and screening holes are formed in the screening middle plate. The bidirectional transporting direction of the bidirectional transporting device is matchedwith arranging positions of the crushing device and the screening device, so that raw coal on the crossheading transloading machine is screened and crushed successively and transported to a belt conveyor. The length of a suspended section is reduced greatly while the lump coal rate is improved, so that the length of a self-moving tail of the belt conveyor is further reduced. The crossheading bidirectional transporting, screening, crushing and transloading system is matched with a complex environment under a coal mine, so that it is ensured that the device is shifted relatively smoothly, problems as a result of too long self-moving tail of the belt are further avoided, and safety accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of reloading machines, in particular to a two-way transport, screening, crushing and reloading system for parallel troughs. Background technique [0002] Raw coal transportation and crushing are necessary processes for coal enterprises to process raw coal. After traditional raw coal is mined, it is unloaded by a scraper conveyor to a trough loader with a crusher (for convenience of description, hereinafter referred to as a crushing trough loader) for crushing, Transshipment, and then unloaded to the belt conveyor, because the raw coal mined is of different sizes, the raw coal is not screened and separated, but all are crushed by the crusher. When the large raw coal is turned into small coal, the small raw coal is also crushed into cinder by the crusher. Or foam coal, resulting in a significant reduction in lump coal rate. [0003] According to the above problems, in order to increase the lump coal rate, som...

AI Technical Summary

Problems solved by technology

[0004] However, the crusher and the screening trough provided on the improved crushing and chute transfer machine with screening function are all arranged in the suspended section, which leads to an increase in the length of the suspended section of the crushing and chute transfer machine, while coal mining underground The environment is complicated, and the overly long suspension section will not only lead to the difficulty of moving the crushing trough transfer machine, but also lead to the lengthening of the self-moving tail of the equipped belt conveyor

Due to the uncontrollable ups and downs of the underground roadway, the self-moving tail of the belt that is too long will cause many problems such as belt deviation, scratching, and inability to move, and even cause safety accidents in serious cases
