At present, in our country mines,the mechanical device machine to the thin coal bed is few, but the coal plow is one kind of low price, simple structure, easy operation mining coal equipment. Therefore it is necessary to carry on the research to design the coal plow.
This article to the coal plow the home, the overseas development situation has carried on the elaboration at present, mainly and stopped the buffer mechanism to the coal plow discount transmission system to conduct the design research anxiously. This article selects by the machinery drive which by the electric motor, the coupler, the reduction gear is composed, provides the power by this equipment to the discount; Through to the discount stress analysis, the union discount actual mining coal process, the use pneumatic actuator principle, designs one to the existing air cylinder slightly transformation to stop the buffer mechanism anxiously.
The discount transmission system impetus discount completes the movement of cutting coal wall, stops the buffer mechanism anxiously, guaranteed the discount moves to work end surface time urgent, reliable, stops safely.
Key word: Coal plow; Transmission system; Stops the buffer mechanism anxiously
