ABSTRACT
Mine car plays an important part in the coal mine underground haulage. The gaugue felt on the bottom of the coal car is one of the common problems on the process of coal production and transportation. To clean the compartment of mine car frequently and promptly is a significant way of raising the efficiency of mine pit rail haulage. No matter the quality of coal, the size composition and water content as well, due to the bad environment of coal production and the vibration in the process of transportation, there always has some coal and other materials left which was very easy to cake on the bottom of the mine car after unloading. If we do not clean these remaining coal and rock meal soonly, they would be heavier and solider, which would increase the weight of mine car so that decrease the effective volume of it. Then it would not only affect the transportation ability of mine car directly and make the intense condition of the transportation system, but also increase the waste of electric power, and even make substantial difficulty in starting the spacial vehicle while transporting the electrical machinery truck. So cleaning the bottom of the mine car become espectially important.
This design add the hydraulic system on the basis of traditional cleaning machine for mechanical mine car. It changes clutch control into the hydraulic control, and is added the multi-channel electromagnetism cross valves which controlled the all round migration of cleaning machine and the movement of the rocking shaft. It also overcomes the shortcoming that the friction control cannot clean the remainings on the bottom of mine car due to its splitting.
