| description | The utility model discloses a hydraulic system of a roof bolter and the roof bolter, relates to the technical field of hydraulic equipment, and mainly aims to realize high and low speed switching of the hydraulic system of the roof bolter on the premise of not adjusting the flow of a multi-way valve. The hydraulic system of the roof bolter comprises a pump station, a working oil port of the multi-way valve is connected with an execution element; the speed regulating valve group comprises a first reversing valve and a one-way throttle valve, and a first oil outlet and a second oil outlet of the first reversing valve are respectively communicated with a first oil inlet of the multi-way valve; an inlet of the one-way throttle valve is communicated with the pump station, a second oil inlet is communicated with the pump station through a pipeline, and an outlet of the one-way throttle valve is communicated with a third oil inlet of the first reversing valve; when the first station is opened, the second oil inlet i |
