| Abstract: | In order to improve the cutting efficiency of the roller shearer and save energy,the roller of the cutting part has been modified and designed,a new type of small-size hydraulic impact cutting tooth and high-performance rotary joint have been designed to realize the accurate transmission of impact force and the transportation of water and hydraulic oil.Based on closed system and load sensing technology,electro-hydraulic control method has been used to drive impact cutting tooth.The working principle of the hydraulic system has been analyzed,the parameters of the main components have been calculated in detail,and the electrical system has been designed to drive the cutting tooth.The reformed shearer has greatly improved in saving electric energy,reducing the amount of coal fragment and dust,and achieved good results. |
