Description

Technical Field

[0001] This invention relates to the field of mining and conveying in fully mechanized mining faces, specifically a multi-point split central trough and scraper conveyor. Background Technology

[0002] Currently, with global population growth and industrial development, the demand for various salts from agriculture and the chemical industry is constantly increasing. However, the largest underground solid salt deposits still rely on room-and-pillar mining methods such as "shortwall mining" and "strip mining," resulting in low extraction rates and poor ventilation, making it difficult to meet the growing demand for salts. Therefore, some mining companies have begun to try longwall retreat mining, a method widely used in coal mines, using fully mechanized mining equipment consisting of mining machines, scraper conveyors, and hydraulic supports. However, due to the differences in the formation process and depth of solid salt deposits compared to coal mines, the roof and floor conditions of the fully mechanized mining face are also significantly different. The arrangement of hydraulic supports no longer follows the one-to-one correspondence with the central trough of the scraper conveyor; the support spacing is no longer the same as the trough length. Furthermore, existing technology only has one shift point in the middle of the central trough, which cannot meet the requirements for support matching. At the same time, the existing technology uses a welded structure where the central trough body and baffle are integrated, resulting in poor versatility, large overall size and weight, which is not conducive to underground transportation. Therefore, to address the above issues, it is necessary to develop a multi-point split central trough and scraper conveyor. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-point split central trough and scraper conveyor to meet the support requirements of fully mechanized mining faces in non-coal solid salt mines, improve the versatility of the trough, increase mining efficiency, and facilitate transportation and installation.

The pin 5 passes through the through hole 37 and the hole 42 in sequence, connecting the pusher ear 4 and the baffle frame 3 into one unit. The pusher part 43 is connected to the hydraulic support through the elongated hole 41, realizing the pushing and pulling of the frame. The connecting plate II 31 of the baffle frame 3 is attached to the connecting plate I 14 of the middle trough 1, so that the connecting pin 311 passes through the pin hole 141, and the connecting bolt passes through the gourd hole I 142 and the connecting hole 312 in sequence. The gourd hole II 143 and the connecting hole 312 connect the baffle frame 3 and the middle trough 1 into one unit.
