Novel thin coal seam overlapped side-unloading structure

Abstract

The invention relates to a working surface scraper conveyer and a reversed transportation roadway loader, and in particular relates to a novel thin coal seam overlapped side-unloading structure. The novel thin coal seam overlapped side-unloading structure comprises a conveyor (8) and a reversed loader (9), and is characterized in that an unloading connection groove (5) is formed in the tail of the reversed loader (9); the head of the conveyor (8) is fixedly lapped to the unloading connection groove (5) in the tail of the reversed loader (9). According to the technical scheme, the problem of unreasonable installation position of a power part caused by an existing end-unloading mode is solved, and the problems of over-hysteresis and non-smooth ventilation of an end hydraulic support and a hydraulic support on a working surface are avoided. According to the technical scheme, by changing the loading mode of the head, the structure of the head and the installation position of the power part, the arrangement spaces of the head of the conveyor, the tail of the reversed loader and the hydraulic supports are improved, the roadway support difficulty of the head is reduced, and the safety and coal mining efficiency of the working surface are improved.

Description

technical field [0001] The invention relates to a scraper conveyor on a working face and a loader on a transport roadway, in particular to a novel thin coal seam overlapping side unloading structure. Background technique [0002] At present, the proportion of thin and extremely thin coal seams in China, especially in old mining areas, is increasing. In order to avoid waste of resources, to achieve balanced exploitation of resources. All mining areas have stepped up efforts to exploit thin and extremely thin coal seams. In order to meet the mining needs of various mining areas, the development and manufacture of fully mechanized mining equipment for thin coal seams, especially ultra-thin coal seams below 1m, has developed rapidly in the coal machinery industry in recent years. [0003] The existing thin coal seam scraper conveyor head unloading methods are all in the form of end unloading. Because the scraper conveyor head adopts the end unloading method, there are many pro...

Problems solved by technology

[0003] The existing thin coal seam scraper conveyor head unloading methods are all in the form of end unloading. Because the scraper conveyor head adopts the end unloading method, there are many problems in the transmission part of the conveyor head in the existing equipment matching. The solution is mainly manifested in the following aspects: 1. The power part adopts the vertical arrangement on the side of the old pond, which causes the end bracket in the slot to lag too much to the side of the old pond, resulting in poor ventilation, and the end frame and the middle frame Difficult support between frames, prone to danger

2. The power part is arranged vertically on the side of the coal wall. Because there is a large drop between the floor of the thin coal seam working face and the floor of the transport roadway, when the shearer is cutting coal at the head, the scattered coal is easy to damage the power part of the head, and the cut coal Unable to enter the reloading machine, the coal needs to be cleaned manually, and the labor intensity of the workers is high

3. The power section is arranged in parallel. Due to the influence of the shape of the reducer, the unloading height of the nose and tail is too large

The head of the conveyor occupies the space above the working surface. When the height of the working surface changes, it is necessary to forcibly cut the bottom at the head and tail of the conveyor, and the workload is heavy.
