Based on the trenchless pipe laying and expanding machine provided in the first embodiment of the present application, the second embodiment of the present application proposes another trenchless pipe laying and expanding machine. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0049] Specifically, the difference of the trenchless pipe laying and expanding machine provided in the second embodiment of the present application is that a filter box 32 is installed on the top of the movable plate 6, a filter bucket 35 is installed inside the filter box 32, a first conveying assembly 22 is installed on the top of the filter box 32, an inlet of the first conveying assembly 22 is fixedly connected to a second tee 30 through a connecting pipe 23, both inlets of the second tee 30 are fixedly connected to suction pipes 24, and an outlet of the first conveying assembly 22 is fixedly connected to a discharge pipe 33;

[0050] The discharge pipe 33 is located above the filter bucket 35, and the other ends of the two suction pipes 24 are respectively connected to the oil outlets of the transmission housing 9 and the planetary reducer 21 to extract the internal oil.

[0051] A second conveying assembly 28 is installed on the top of the movable plate 6, and a mounting pipe 29 is fixedly connected to the inlet of the second conveying assembly 28, and a heat exchanger 31 is installed at the other end of the mounting pipe 29, and a docking pipe 34 is fixedly connected to the inlet of the heat exchanger 31, and a first tee 26 is installed at the outlet of the second conveying assembly 28 through a fixed pipe 27, and two outlets of the first tee 26 are fixedly connected to conveying pipes 25;

[0052] The other end of the butt pipe 34 is connected to the back side of the filter box 32 near the bottom. The heat exchanger 31 is an existing heat dissipation structure that can cool down the hot lubricating oil. The other ends of the two delivery pipes 25 are respectively connected to the oil inlets of the transmission housing 9 and the planetary reducer 21 to re-deliver the cooled and filtered lubricating oil to the transmission housing 9 and the planetary reducer 21.

[0053] The first conveying assembly 22 comprises a protective shell 221, the front and back of the protective shell 221 are provided with heat dissipation holes 223, and a conveying pump 222 is installed inside the protective shell 221;

The outlet of the first conveying component 22 conveys the extracted oil to the inside of the filter box 32 through the discharge pipe 33. The lubricating oil liquid filtered by the filter box 32 enters the heat exchanger 31 for cooling, and then the cooled lubricating oil liquid is returned to the inside of the planetary reducer 21 and the transmission housing 9 through the second conveying component 28. Through this structure, the lubricating oil liquid inside the planetary reducer 21 and the transmission housing 9 can be stabilized in the corresponding temperature range, ensuring the viscosity of the lubricating oil liquid, thereby lubricating the gears inside the transmission housing 9 and the planetary reducer 21, which is beneficial to prolonging the service life of the internal dimensions of the planetary reducer 21 and the transmission housing 9.
