摘   要
 礦車在煤礦井下運輸中占有十分重要的地位，煤矸粘結礦車車底是煤礦生產運輸過程中存在的一個普遍問題。經常而及使地清掃礦車車箱式提高礦井軌道運輸效率的重要因素。不論煤質，粒度組成及含水量如何，由于煤礦生產環境的惡劣，加之在運輸的過程中的振動等原因，卸車之后總會有少量的煤炭，煤矸等易粘結的物料粘結在礦車車箱底部及鄰幫若不將這些殘留煤，巖粉及時清除干凈，則會越積越厚，越積越結識，增加了礦車自重，使礦車的有效容積減少，它不僅直接影響著礦車的運輸能力，造成了運輸系統的緊張狀況，而且增加了電力資源的浪費，甚至使電機車運輸是空列起動發生困難，所以清理車底的問題，在煤礦就顯得尤為重要。
 本設計在傳統機械礦車清車機的基礎上加入了液壓系統，由摩擦離合器控制行走部該為液壓控制，安裝了多路電磁換向閥，分別控制清車機前后，左右的移動以及搖臂的運動，克服了摩擦離合控制因打滑無法清理礦車車底粘結物的弊端。

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.
