Problems solved by technology

However, in the case of poor geological conditions (especially hard coal), in the process of planing the coal wall, a single plow not only has a weak ability to cut hard coal, but also the plow and coal wall will appear The stagnation phenomenon between the chains can easily cause chain breaking accidents and affect normal production
For the coal mining system, once an accident occurs, it will cause a long shutdown and seriously affect the output

Abstract

The invention discloses a coal plow, which comprises: a first plow head, a punching device, a traction assembly for pulling the first plowing head and the punching device, and a carriage guide rail; wherein , the first planer is adjacent to the punching device and is arranged on the carriage guide rail, and can reciprocate along the carriage guide rail through the traction assembly. Therefore, the coal plow of the present invention can effectively reduce chain-breaking shutdown accidents caused by the plow head stuck in the coal wall.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a coal plow. Background technique [0002] Generally speaking, a coal plow includes a coal plowing unit, a conveying unit, a hydraulic propulsion system, a spray dust suppression system, an electrical system, and auxiliary devices. The coal plowing part mainly includes the plow head and its driving device, the carriage guide rail matched with the plow head, plow chain and other components. Among them, the planer head cloth is equipped with knife holders, and planer knives are arranged on each knife holder. The planer head is connected with the planer chain through the link seat to form a closed working chain, and the planer chain is guided by the slide rail to form a closed loop. The upper chain and the lower chain are respectively located in the upper and lower chain grooves of the carriage guide rail. [0003] During the mining process of existing coal plows, usually unde...
