[0002] The hydraulic power unit of a garbage dump truck is a device that provides hydraulic power for the dump truck. It drives the lifting, holding, and lowering of the carriage through a hydraulic system to achieve the automatic dumping of garbage. It is the core part of the hydraulic system of the dump truck, responsible for converting mechanical energy into hydraulic energy to provide power for the entire system. Currently, the hydraulic power unit of a garbage dump truck usually installs an oil pump, oil pipes, etc. on the seat plate, and then fixes a protective cover and the like on the seat plate through multiple bolts to shield the oil pump and oil pipes. Since it installs the protective cover through bolts or screws, when it needs to be disassembled, specific tools are required to disassemble multiple bolts one by one, and the operation is relatively cumbersome.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-6A hydraulic power unit for a garbage dump truck includes a base 1, with mounting blocks 2 installed on the surface of the base 1, and a partition 3 installed at the top of the base 1. An oil pump 4 is mounted on one side of the partition 3, and an oil outlet pipe 5 is mounted on the surface of the oil pump 4. An oil tank 6 connected to the oil pump 4 is mounted on the other side of the partition 3, and an oil inlet pipe 7 is mounted on the surface of the oil tank 6. A first mounting groove 8 with a "U"-shaped cross-section is opened at the top of the base 1, and a protective cover 9 is installed inside the first mounting groove 8. An mounting pipe 10 is installed at the top of the protective cover 9, and an annular plate 11 is threadedly connected to the surface of the mounting pipe 10. The inner wall of plate 11 has a groove 12, and a slider 13 is slidably connected inside the groove 12. A connecting rod 14 is connected to one side of the slider 13, and a pressing block 15 is connected to the bottom end of the connecting rod 14. The base 1 has a second mounting groove 16 with a "+" shaped cross-section inside, and a fixing plate 17 is provided on the inner wall of the second mounting groove 16. A spring 18 is connected to one side of the fixing plate 17, and a movable plate 19, which is slidably connected to the inside of the second mounting groove 16, is connected to one side of the spring 18. A fixing rod 20, which is movably sleeved with the fixing plate 17, is connected to the surface of the movable plate 19. One side of the protective cover 9 is connected to an extrusion ball 21 that contacts the extrusion block 15. Fixing holes 22 for connecting to the fixing rod 20 are respectively opened around the surface of the protective cover 9. A valve is installed on the base 1 to facilitate the installation of the protective cover 9 inside the first mounting slot 8 to shield the oil pump 4 and oil tank 6. The protective cover 9 can also be disassembled simply by rotating the annular plate 11, making operation simple and eliminating the need for specific tools to disassemble multiple bolts one by one. A through groove is opened on the protective cover 9 to facilitate the entry and exit of oil pipes. A connecting groove is opened at the top of the partition 3 to facilitate moving the mounting pipe 10 to the second mounting slot. The interior of the mounting groove 16 is designed to facilitate the movement of the connecting rod 14 through the moving groove 23 after the protective cover 9 is connected to the interior of the first mounting groove 8. This allows the annular plate 11 to rotate via the sliding groove 12 on the surface of the slider 13, thereby moving the conical or spherical extrusion block 15 to the surface of the extrusion ball 21 and extruding it. This allows the extrusion ball 21 to move the fixing rod 20, which can then be moved into the fixing hole 22 to limit the protective cover 9. Conversely, this also facilitates its disassembly without the need to use specific tools to disassemble multiple bolts one by one.

[0030] Furthermore, the length and width of the first mounting groove 8 are the same as the length and width of the protective cover 9. The first mounting groove 8 is designed according to the shape of the protective cover 9 to avoid gaps between them, which would prevent the fixing holes 22 on the protective cover 9 from being aligned with the fixing rod 20.

[0031] Furthermore, the diameter of the fixing rod 20 is the same as the inner diameter of the fixing hole 22, in order to avoid gaps between them, which could cause the protective cover 9 to shake.

[0032] Furthermore, the surface of the mounting tube 10 is provided with a moving groove 23 for the connecting rod 14 to move, which facilitates the connecting rod 14 to move through the moving groove 23 when the annular plate 11 rotates and moves.

[0033] Furthermore, the mounting tube 10 is threadedly connected to the positioning plate 24, and the bottom end of the positioning plate 24 is connected to the positioning rod 25 that contacts the top end of the annular plate 11. The positioning plate 24 and the annular plate 11 are threaded in opposite directions. The annular plate 11 is threaded in the forward direction at the moving groove 23 on the surface of the mounting tube 10, while the positioning plate 24 is threaded in the reverse direction above the moving groove 23 on the surface of the mounting tube 10. This is to prevent the annular plate 11 from loosening due to vehicle vibration.

[0034] Furthermore, the inner wall of the second mounting groove 16 is provided with a stop 26 for blocking the moving plate 19, which prevents the spring 18 from ejecting the moving plate 19 from the inside of the second mounting groove 16.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
