[0021] See also Figures 1-2 A hydraulic system of a crawler mobile screening station is arranged on a mounting frame 100 and its outer layer is covered with an external cover, and windows are respectively opened on the front and rear sides of the external cover.
[0022] The hydraulic system of the crawler mobile screening station includes a hydraulic oil tank 10, a radiator 20, and a hydraulic power assembly 30, which are arranged on a mounting frame 100.

A maintenance space 70 is left between the hydraulic oil tank 10 and the hydraulic power assembly 30. A travel motor electromagnetic control valve assembly 40 is arranged above the hydraulic oil tank 10. The travel motor electromagnetic control valve assembly 40 is located above the mounting frame 100 and close to the maintenance space 70. The radiator 20 is arranged below the mounting frame 100.
[0023] The hydraulic system of the crawler mobile screening station also includes a manually controlled hydraulic valve group 50 and an oil return steel pipe assembly 60. The manually controlled hydraulic valve group 50 and the oil return steel pipe assembly 60 are respectively arranged on the mounting frame 100 and close to another window. The manually controlled hydraulic valve group 50 is integrated by the feeder control valve assembly 51, the vibrating screen control valve assembly 52, the large material screen control valve assembly 53, and the fine material screen control valve assembly 54. The oil return steel pipe assembly 60 is used to collect the return oil of the hydraulic system of the crawler mobile screening station.
[0024] In this embodiment, the return oil steel pipe assembly 60 is connected to the feeder control valve assembly 51, the vibrating screen control valve assembly 52, the large material screen control valve assembly 53, the fine material screen control valve assembly 54, the travel motor electromagnetic control valve assembly 40, and the hydraulic oil tank 10 through the return oil pipeline. The return oil steel pipe assembly 60 can reduce the space occupied by the return oil pipeline and avoid the scattered layout of the return oil pipeline.
[0025] The hydraulic system of the crawler mobile screening station provided in this embodiment arranges the travel motor electromagnetic control valve assembly 40 and the radiator 20 in the upper space and the lower space of the mounting frame 100 respectively. This upper and lower arrangement reduces the horizontal space occupation of the hydraulic system and provides sufficient inspection and maintenance space for the radiator 20 and the travel motor electromagnetic control valve assembly 40; the feeder control valve assembly 51, the vibrating screen control valve assembly 52, the large material screen control valve assembly 53, and the fine material screen control valve assembly 54 are integrated to reduce the space occupation of the hydraulic system; the return oil steel pipe assembly 60 is provided to reduce the space occupation of the return oil pipeline and avoid the return oil pipeline being arranged too scattered, thereby reducing the space occupation of the hydraulic system and improving the convenience of inspection and maintenance; the hydraulic oil tank 10, the hydraulic power assembly 30, the manual control hydraulic valve group 50, and the return oil steel pipe assembly 60 are all close to the window and the distance between the arrangement positions is moderate, which is very convenient for observation, inspection and maintenance.
[0026] See also Figures 1-2 The hydraulic oil tank 10 is arranged at either side corner of the mounting frame 100, and the hydraulic power assembly 30 is arranged at the other side edge of the mounting frame 100 where the hydraulic oil tank 10 is arranged. In this embodiment, the hydraulic oil tank 10 is arranged at the left rear corner of the mounting frame 100, close to the rear window of the external cover, and the hydraulic power assembly 30 is arranged at the right side edge of the mounting frame 100. This arrangement ensures sufficient inspection and maintenance space on both sides of the hydraulic oil tank 10, and also maximizes the inspection space 70 between the hydraulic oil tank 10 and the hydraulic power assembly 30, making it easier for staff to inspect and maintain the travel motor solenoid control valve assembly 40.
[0027] Furthermore, the radiator 20 is located below the hydraulic power assembly 30. In this embodiment, the radiator 20 is arranged in the lower space of the right rear corner of the hydraulic power assembly 30.
[0028] Specifically, the travel motor solenoid control valve assembly 40 is mounted on the oil tank cover 11 of the hydraulic oil tank 10 and is located on a side edge of the upper surface of the oil tank cover 11 near the maintenance space 70. In this embodiment, the travel motor solenoid control valve assembly 40 is located on the right side of the oil tank cover 11 and near the maintenance space 70 for easy maintenance.
[0029] Specifically, the manual control hydraulic valve assembly 50 and the hydraulic oil tank 10 are arranged in the front-to-back direction on the mounting frame 100. In this embodiment, the manual control hydraulic valve assembly 50 is arranged in front of the hydraulic oil tank 10, so that the manual control hydraulic valve assembly 50 can avoid the maintenance space 70 between the hydraulic oil tank 10 and the hydraulic power assembly 30, making the layout structure of the hydraulic system more compact.
[0030] Furthermore, the manually controlled hydraulic valve assembly 50 is mounted on a side edge of the mounting frame 100 via a mounting bracket 55. The feeder control valve assembly 51, vibrating screen control valve assembly 52, large material screen control valve assembly 53, and fine material screen control valve assembly 54 are sequentially arranged on the mounting bracket 55. In this embodiment, the mounting bracket 55 is positioned at the front side edge of the mounting frame 100. The manually controlled hydraulic valve assembly 50 integrates the feeder control valve assembly 51, vibrating screen control valve assembly 52, large material screen control valve assembly 53, and fine material screen control valve assembly 54 from right to left on the side of the mounting bracket 55 according to their respective actuation locations. This makes the hydraulic system's control valves simple to operate and easy to inspect and maintain.
[0031] Specifically, the hydraulic power assembly 30 includes a main pump 31 and an auxiliary pump 32. Both the main pump 31 and the auxiliary pump 32 are located on the same side of the mounting frame 100 as the manually controlled hydraulic valve assembly 50, near another window. In this embodiment, the main pump 31, the auxiliary pump 32, and the manually controlled hydraulic valve assembly 50 are located on the front edge of the mounting frame 100, near a window on the front side of the external housing. This facilitates operator operation, inspection, or maintenance of the main pump 31, the auxiliary pump 32, and the manually controlled hydraulic valve assembly 50, all on the same side of the mounting frame 100.
[0032] Specifically, an installation gap is left between the manual control hydraulic valve group 50 and the hydraulic oil tank 10 .
[0033] Furthermore, the oil return steel pipe assembly 60 is arranged within the installation gap. Placing the oil return steel pipe assembly 60 within the installation gap shortens the length of the oil return line connecting each of the control valve assemblies to the oil return steel pipe assembly 60, reduces the space occupied by the entire hydraulic system, and makes the layout of the oil return line simpler and neater.
[0034] The advantages of the hydraulic system of the crawler mobile screening station provided in this embodiment include:
[0035] (1) The horizontal space occupied by the hydraulic system is reduced, and the space utilization rate of the hydraulic system is improved. The distance between the hydraulic components is moderate, which is very convenient for inspection and maintenance.
[0036] (2) The integration and modularization of each control valve assembly reduces the space occupied by the entire hydraulic system and makes the layout of the hydraulic system more concise.
[0037] (3) The length of each oil return line is shortened, which reduces the space occupied by the entire hydraulic system and makes the layout of the oil return line simpler and neater.
[0038] (4) The hydraulic oil tank 10, the fine material screen control valve assembly 54, the large material screen control valve assembly 53, the vibrating screen control valve assembly 52, the feeder control valve assembly 51, the return oil steel pipe assembly 60, the main pump 31, and the auxiliary pump 32 are all close to the window of the external cover, which is convenient for observation and maintenance. The distance between the locations is moderate, which is very convenient for inspection and maintenance.
