The general excavator water pump head is a device designed to work with the hydraulic system of the excavator, which can realize efficient water pumping.

[0003] The excavator water pump heads on the market are mostly specially designed and matched with specific models of excavators. These water pump heads are usually connected with the excavator through bolts, clamps or special interfaces.

[0004] However, the connecting structure of the water pump head and the excavator on the market has the problems of complex installation, easy loosening and the like, which affects the efficiency and safety of water pumping. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a general excavator water pump head connecting structure, which realizes the quick and stable connection of the water pump head and the excavator by optimizing the connection mode and structural design.

[0007] By adopting the above technical scheme, the connecting sleeve with the guide groove and the H-shaped groove is matched with the abutting block, that is, the abutting block slides into the guide groove, slides along the path of the H-shaped groove and is finally clamped at the end of the H-shaped groove away from the guide groove, so as to complete the locking of the axial direction of the connecting sleeve. When disassembly is needed, the connecting plate is controlled by the mechanical arm, and the abutting block is pulled out along the path of the H-shaped groove. Thus, the quick connection and disassembly between the water pump head (i.e. the water suction pump part) and the mechanical arm of the excavator are realized. This structure simplifies the installation steps and improves the work efficiency, especially when the water pumping position needs to be frequently changed or adjusted, which can significantly save time.

[0008] Further, the guide groove, the H-shaped groove and the abutting block are arranged in pairs and are respectively arranged on the left and right sides of the connecting plate.

[0009] By adopting the above technical scheme, the guide groove and the H-shaped groove are arranged on the left and right sides at the same time, and the corresponding abutting block is arranged, additional connection structure is increased, further stable connection is achieved, and the fixing of the connecting sleeve on the connecting plate is more balanced and stable.

[0014] Further, one end of the bolt column is fixedly provided with a pull ring.

[0015] By adopting the above technical scheme, the design of the pull ring makes it more convenient for the operator to grasp and operate the bolt column.

[0017] By adopting the technical scheme, the circumferential array layout of the plurality of stable assemblies makes the connection between the fixing block and the object to be fixed more uniform and stable. This layout can effectively disperse and resist forces from various directions, thereby enhancing the overall stability and firmness and reducing the risk of loosening or damage caused by excessive force on a single point.

[0018] Further, the water suction pipe is fixedly connected with a filter screen at one end.

[0019] By adopting the technical scheme, the filter screen can effectively block impurities, silt and other particulate matters in the water from entering the water suction pipe, thereby preventing these particulate matters from causing wear or blockage inside the water suction pump, prolonging the service life of the water suction pump and ensuring its normal operation.

[0020] Further, the water drainage pipe is detachably connected with a water collecting tank at one end.

[0021] By adopting the technical scheme, the detachable connection design of the water collecting tank makes the entire water pumping system more flexible and variable. When the pumped water needs to be used again or needs to be discharged over a long distance, the water collecting tank can serve as a storage medium, thereby adapting to different transportation tasks. If there is no such requirement, the water drainage pipe can also be directly connected with the water collecting tank to discharge the pumped water to a designated area, and this flexibility improves the adaptability and working efficiency of the equipment.

[0034] Through the cooperation of the connecting sleeve 4 with the guide groove 41 and the L-shaped groove 42 and the abutting block 3, that is, the abutting block 3 slides into the guide groove 41, slides along the path of the L-shaped groove 42 and is finally clamped at one end of the L-shaped groove 42 away from the guide groove 41, the axial locking of the connecting sleeve 4 is completed. When disassembly is needed, the abutting block 3 is pulled out along the path of the L-shaped groove 42 by controlling the connecting plate 2 by the mechanical arm 1. Thus, the quick connection and disassembly between the water pump head (i.e. the water suction pump 5 part) and the excavator mechanical arm 1 are realized. This structure simplifies the installation steps and improves the work efficiency, especially when the water suction position needs to be frequently changed or adjusted, which can significantly save time.

[0035] In this embodiment, the guide groove 41, the H-shaped groove 42 and the abutting block 3 are provided in pairs and are located on the left and right sides of the connecting plate 2. By simultaneously providing the guide groove 41 and the H-shaped groove 42 on the left and right sides, and the corresponding abutting block 3, additional connection structures are added, further stabilizing the connection, making the fixing of the connecting sleeve 4 on the connecting plate 2 more balanced and stable. This double-point support structure design can effectively resist forces and torques from different directions, prevent the water pump head from shaking or shifting during operation, and enhance the stability of the device.

[0036] In this embodiment, the connecting plate 2 is provided with a stabilizing assembly for limiting the rotation of the connecting sleeve 4, which includes a fixed block 6 fixedly arranged on the connecting plate 2, a stabilizing groove body 61 fixedly arranged on the fixed block 6, a plug-in column 62 inserted into the stabilizing groove body 61, and a connecting groove body 63 fixedly arranged on the connecting sleeve 4 and matched with the plug-in column 62.

[0037] Considering that the water pump head will vibrate during operation, which may cause loosening or relative rotation between the connecting sleeve 4 and the connecting plate 2, affecting the stability and service life of the water pump.

The design of the pull ring 71 makes it easier for the operator to grasp and operate the plug-in column 62. Without the need for special tools or precise alignment, the unlocking action can be completed simply by pulling the plug-in column 62 through the pull ring 71. This design greatly simplifies the operation process and improves work efficiency.

[0040] In this embodiment, two stabilizing assemblies are provided, which are arranged on the left and right sides of the fixing block 6. The circumferential array layout of the plurality of stabilizing assemblies makes the connection between the fixing block 6 and the object to be fixed more uniform and stable. This layout can effectively disperse and resist forces from various directions, thereby enhancing the overall stability and firmness and reducing the risk of loosening or damage caused by excessive force on a single point.

[0041] In this embodiment, the water suction pipe 51 is fixedly connected with a filter screen 8 at one end. The filter screen 8 can effectively block impurities, sand and other particulate matters in the water from entering the water suction pipe 51, thereby preventing these particulate matters from causing wear or blockage inside the water suction pump 5, prolonging the service life of the water suction pump 5 and ensuring its normal operation.

[0042] In this embodiment, the water discharge pipe 52 is detachably connected with a water collecting tank 9 at one end. In this embodiment, the water collecting tank 9 is fixedly installed on the body of the excavator to ensure that the water pumping work can be smoothly carried out in a larger range. The detachable connection design of the water collecting tank 9 makes the entire water pumping system more flexible and variable. When the pumped water needs to be reused or needs to be discharged over a long distance, the water collecting tank 9 can serve as a storage medium, thereby adapting to different transportation tasks. If there is no such need, the water discharge pipe 52 can also be directly connected to the designated area without the water collecting tank 9, which improves the adaptability and working efficiency of the equipment.

[0044] First, the latch post 62 is pulled out of the stabilizing groove body 61 by a suitable distance by the pull ring 71, and the connecting sleeve 4 is placed on the ground. By controlling the mechanical arm 1, the guide groove 41 is aligned with the abutment block 3 on the connecting plate 2. After alignment, the mechanical arm 1 drives the connecting plate 2 into the connecting sleeve 4, and the abutment block 3 slides into the guide groove 41. When the connecting plate 2 cannot continue to push, the mechanical arm 1 is lifted and drives the abutment block 3 to move along the path of the L-shaped groove 42 until the abutment block 3 reaches the end of the L-shaped groove 42 (i.e., the end of the L-shaped groove 42 away from the guide groove 41). At this time, the connecting sleeve 4 is axially locked, realizing the quick connection between the water pumping head (i.e., the water suction pump 5 part) and the excavator mechanical arm 1.

[0045] When the axial locking of the connecting sleeve 4 is completed, the pulling force applied to the latch post 62 is removed, and the connecting spring 7 is reset under the action of its own elastic force, driving the latch post 62 to be inserted into the connecting sleeve 4, realizing the circumferential locking of the connecting sleeve 4 and improving the stability of the device.

[0046] When disassembly is needed, the movement of the connecting plate 2 is controlled by the mechanical arm 1, the abutting block 3 is taken out along the path of the Z-shaped groove 42, the connecting plate 2 is taken out in the direction away from the connecting sleeve 4, so that the quick disassembly between the water pump head (i.e. the water suction pump 5 part) and the excavator mechanical arm 1 is realized.

[0047] The embodiments of the present specific embodiment are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
