Embodiment 1
[0043] figure 1 It is a schematic structural diagram of the oil injection device provided in Embodiment 1 of the present invention, figure 2 It is a schematic diagram of the shape of the gun nozzle in the oil injection device provided by Embodiment 1 of the present invention. Embodiment 1 of the present invention provides an oil injection device, such as figure 1 As shown, it includes a gun nozzle 1, an end cover 2 and an oil cylinder 3, wherein a piston 6 is arranged in the oil cylinder 3, and the oil cylinder 3 is divided into two parts: a grease chamber 4 and a pressure chamber 5 by the piston 6; the pressure chamber 5 is provided with a liquid inlet , used to communicate with the pressure liquid power source 12 through the introduction pipeline 8, and push the piston 6 to move toward the grease chamber 4 by filling the pressure chamber 5 with pressure liquid; the grease chamber 4 is provided with a spring 7, and the first end of the spring 7 Butt against the end cover 2,...
Embodiment 2
[0049] image 3 The structure diagram of the oil injection device provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention provides an oil injection device. The difference from Embodiment 1 is that the pressure chamber 5 is further provided with a liquid outlet, and the liquid outlet is passed through the outlet pipeline. 9 is connected to the outside world 13, such as image 3 As shown, it is used to discharge the pressure liquid in the pressure chamber 5. The liquid inlet and the liquid outlet can be two independent openings, preferably as in this embodiment image 3 As shown, the liquid inlet and the liquid outlet are the same opening, and the inlet pipeline 8 and the outlet pipeline 9 communicate with the opening through a common pipeline.
[0050] Further, a pressure inlet valve 10 is provided in the introduction pipeline 8 connected to the liquid inlet to switch the conduction and disconnection of the introduction pipeline 8 when the pre...
