Hard ore ming and transporting equipment

Abstract

The invention relates to the field of coal mining mechanical equipment, in particular to hard ore mining and transporting equipment which comprises milling equipment and semi-open type material transporting equipment which are matched for use, the semi-open type material transporting equipment comprises a non-closed base, an open-close scraper blade and a chain, and the chain drives the open-close type scraper blade to slide on the non-closed type base; the non-closed base comprises a ledge, a scraper supporting plane and a scraper supporting inclined plane which are connected in sequence, the ledge is arranged close to the milling equipment, and the scraper supporting inclined plane inclines towards a coal seam bottom plate in the direction away from the ledge; a baffle is hinged to one end of the open-close type scraper blade and is lapped on the scraper blade supporting inclined surface. A rocker arm and a multi-gear traditional system are replaced by a vertical height adjusting structure, so that the milling equipment can be more suitable for cutting high-hardness ores while the reliability of the equipment is improved. According to the semi-open type material conveying equipment, the range of the falling ore receiving area of the material conveyor is enlarged, and the ore extraction and conveying efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of coal mining machinery and equipment, especially hard ore mining and transport equipment. Background technique [0002] Ore mining equipment, transportation equipment and equipment support apparatus constitutes a major ore mining face. Existing ore mining equipment, comprising a shearer, planer, etc., it is difficult to drive both chain length and the height of mining, etc., not hard ore mined condition; Further, both sides of the central groove of the conventional material handling equipment there above to help protect the central groove, for preventing transmission in the central groove coal fall out. But at the same time help protect the outside and below the coal can not fall into the middle slot for transmission, resulting in waste mined. Inventive content [0003] The present invention aims to solve the above problems, there is provided a hard ore mining and transport equipment, which employs the following...

AI Technical Summary

Problems solved by technology

Existing ore mining equipment, including coal shearers, coal plows, etc., is difficult to take into account the length of the transmission chain and the mining height, etc., and is not suitable for the working conditions of hard ore mining; There is an apron that is higher than the middle trough, which is used to prevent the coal and rock transported on the middle trough from falling out

But at the same time, the coal and rock on the outside and below the sidewall cannot fall into the middle trough for transmission, resulting in mining waste
