[0038] Reference Figures 2 to 5The base 1 is formed with two oil circuits, which are divided into an oil suction pipeline 11 and an oil outlet pipeline 12. The oil circuits are centrally integrated into the base 1; the manual pump 2 and the electric pump 3 are installed side by side on the base 1 along the first direction, and the manual pump 2 is correspondingly connected to the two first ports 13, and the electric pump 3 is correspondingly connected to the two second ports 14, so that the electric pump 3 and the manual pump 2 use the same oil circuit, and there is no need to use a steel plate to connect the whole, and a steel pipe or a hose to connect the oil circuit, the overall weight is reduced, the integration is high, the layout space is saved, the structure is more compact and firm, and the outer diameter of the sealing ring 4 can be adjusted to be more suitable for the second port 14 to ensure the sealing performance.

[0039] Further, refer to Figures 3 to 5 In this embodiment, the base 1 is further provided with a connecting pipeline 15, which is connected to the middle parts of the two oil circuits respectively, and the connecting pipeline 15 includes a third port 151 for connecting to the external environment; the integrated cab hydraulic tilt oil pump also includes a reversing valve 5, and the reversing valve 5 is installed in the connecting pipeline 15 from the third port 151. In this way, the oil flow in the two oil circuits can be connected, cut off and reversed, thereby ensuring the normal operation of the integrated cab hydraulic tilt oil pump.

[0040] Furthermore, in this embodiment, referring to Figure 4 and Figure 5 The manual pump 2 includes an oil tank and a pump body arranged in the oil tank, and the manual pump 2 is connected to the two first ports 13; the connecting pipeline 15 is arranged corresponding to the first port 13 and is located at the lower side of the first port 13; in order to ensure the sealing performance, the connecting pipeline 15 is connected to the first port 13 through the connecting hole 17, and the connecting hole 17 is a small hole, and the aperture of the connecting hole 17 is smaller than the mounting hole 16, one end of the mounting hole 16 is exposed to the external environment and constitutes the first port 13, and the sealing ring 4 is installed in the mounting hole 16; in this way, the sealing performance is guaranteed while ensuring that the oil circuit can enter or discharge oil through the first port 13.

[0041] In this embodiment, refer to Figures 1 to 3 The first port 13 and the second port 14 are both formed on the upper end surface of the base 1, and the oil tank is installed on the base 1 in a vertical state, which maximizes the oil storage capacity, has high integration and compact structure.

[0042] Specifically, the manual pump 2 includes an oil tank and a pump body arranged in the oil tank. The materials of the oil tank and the base 1 are both aluminum alloy.
