As countries coal-more reduce, shallow coal seams have become the new development resource. Study design to plow head can also make our carbon energy get reasonable effectivly mining. The coal plough which stand for the mining machinerys development is getting more and more important. However automated coal plough basically by overseas monopoly, domestically produced coal plough faced with huge challenge. This article through to set the sliding plough as an example,the dissereation has carried on the study about the working condition parameter of the coal plough-cutting depth ,planing rate,the struction of the plow head and force analysis. The plow head is coal ploughs prime task organization, which has distinguishes between the other machinerys important technical feature .Plow head on cutting by planer chain traction, so the plane chain reasonable directly influence degree plough performance. Hydraulic tight chain device is to keep the traction chain has an appropriate tightness degree, and disassembling the need of traction chain, shaver with tight chain should plow in its research, so device design has the extremely vital significance.
