摘要（英）：

The invention discloses an emulsion power hydraulic system of a shearer, and belongs to the field of underground shearer power devices. The technical problem to be solved is to provide the emulsion power hydraulic system of the shearer which is simple in structure and convenient to use. The technical scheme for solving the technical problem is that the emulsion power hydraulic system of the shearer comprises an emulsion pump station, a left height regulating oil cylinder, a right height regulating oil cylinder and a brake, and the emulsion power hydraulic system further comprises a first pressure reducing valve, a second pressure reducing valve, a stop valve, a filter and an electro-hydraulic reversing valve, wherein the inlet of the first pressure reducing valve is connected with the emulsion pump station, the outlet of the first pressure reducing valve is connected with the inlet of the stop valve, the outlet of the stop valve is connected with the inlet of the filter, the outlet ofthe filter is connected with the electro-hydraulic reversing valve, the electro-hydraulic reversing valve is connected with the left height regulating oil cylinder, the right height regulating oil cylinder and the brake, and a second pressure reducing valve is arranged on a pipeline connected with the brake. The emulsion power hydraulic system of the shearer can be widely applied to the field of underground shearer power devices.
