[0008] Moreover, the liquid collecting assembly includes a liquid collecting tank support ring, a liquid collecting tank body and an air riser plugging plate. The liquid collecting tank support ring is fixedly connected to the upper part of the oil collecting tank body. The liquid collecting tank body is evenly arranged on the upper part of the liquid collecting tank support ring. The air riser plugging plate is fixedly connected to both sides of the liquid collecting tank body.

[0009] Moreover, the bottom plate of the liquid collecting channel is inclined toward both sides to draw out the bucket body.

[0010] Moreover, the liquid collecting tank body is inclined toward the middle liquid collecting channel.

[0011] Moreover, a liquid baffle is slidably connected to the upper portion of the liquid collecting tank body.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, through the coordination between the pull-out bucket support ring, the pull-out bucket body, the liquid collecting tank support ring, the liquid collecting tank body and the lift pipe blocking plate, the unequal height lift cylinder oil collecting tank can effectively reduce the coking and blockage inside the oil collecting tank, thereby improving the stability of the oil supply.
