[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-Figure 3 As shown, a hydraulic control device for a compound machine comprises a control cylinder body 1 and a docking cylinder body 2, a control rotating rod 3 is movably installed on one side of the control cylinder body 1, a control handle 4 is fixedly installed on the outer side of the control rotating rod 3, docking rotating teeth 5 are movably installed on the other side of the control cylinder body 1 and both sides of the docking cylinder body 2, docking pipe joints 7 are fixedly installed on the front and rear ends of the control cylinder body 1 and the docking cylinder body 2, a docking pipe 8 is installed on the inner thread of the docking pipe joint 7, a mounting platform 9 is integrally formed on the upper ends of the control cylinder body 1 and the docking cylinder body 2, a plurality of pipe sealing covers 10 are threadedly installed on the upper end of the mounting platform 9, a guide pipe 11 is fixedly installed inside the control cylinder body 1 and the docking cylinder body 2, a control pipe 12 is movably installed inside the control cylinder body 1 and the docking cylinder body 2 below the guide pipe 11, and a plurality of guide holes 13 are opened on the outer side of the control pipe 12.

[0018] In this embodiment, the control cylinder body 1 is located on one side of the docking cylinder body 2, and the number of docking cylinder bodies 2 is several. If each docking cylinder body 2 is installed in a straight line with the control cylinder body 1, the docking cylinder bodies 2 can be increased or decreased according to the number used.

[0019] In this embodiment, screw fixing holes 14 are provided at the four corners of the control cylinder body 1 and the docking cylinder body 2. The front and rear ends of the control cylinder body 1 and the docking cylinder body 2 are located above the docking pipe joint 7 and are threadedly installed with overflow valves 6. The overflow valve 6 is through-connected to the interior of the control cylinder body 1 and the docking cylinder body 2, and the screw fixing holes 14 are used to pass the screws. The overflow valve 6 plays the role of overflow in the control cylinder body 1 and the docking cylinder body 2.

[0020] In this embodiment, both ends of the control pipe 12 in the docking cylinder 2 are fixedly connected to the docking rotating teeth 5, and both ends of the control pipe 12 in the control cylinder 1 are respectively fixedly connected to the control rotating rod 3 and the docking rotating teeth 5, and every two docking rotating teeth 5 are matched and connected, and the docking rotating teeth 5 play the role of docking transmission.

[0021] In this embodiment, both ends of the docking pipe 8 are installed in the front and rear docking pipe joints 7, and the docking pipe 8 is connected to the inside of the control cylinder 1 and the docking cylinder 2, and the docking pipe 8 plays a role in conveying hydraulic oil.

[0022] In this embodiment, the upper end of the diversion pipe 11 is closely connected to the pipe sealing cover 10 , the lower end of the diversion pipe 11 is located above the diversion hole 13 , and the pipe sealing cover 10 seals the diversion pipe 11 .

[0023] It should be noted that the utility model is a hydraulic control device for a compound machine. When in use, the control cylinder body 1 is the main body of the device. After the pipeline sealing cover 10 on the mounting platform 9 is removed, the pipeline for inputting hydraulic pressure and the hydraulic pipeline outputting to the compound machine are installed respectively. The input hydraulic pressure enters the control cylinder body 1. When in the open state, the hydraulic oil passes through the central guide hole 13 in the control cylinder body 1 into the control pipeline 12, and then enters the guide pipeline 11 along the guide holes 13 on both sides of the control pipeline 12. The hydraulic oil is transported to the output hydraulic pipeline by the guide pipeline 11, so that the hydraulic oil enters the compound machine for hydraulic opening. After the control rotating rod 3 is rotated by the control handle 4, the control rotating rod 3 drives the control pipeline 12 to rotate, and the guide holes 13 on both sides of the control pipeline 12 are disconnected from the guide pipeline 11, so that the hydraulic oil cannot be carried out. The output of the compound machine can realize the hydraulic closure of the compound machine, and when multiple groups of hydraulic control are needed, the docking cylinder 2 can also be connected to the hydraulic pipeline at the same time, and then the docking cylinder 2 uses the docking rotating teeth 5 on both sides to dock with the docking rotating teeth 5 on one side of the control cylinder 1. Therefore, when the control pipeline 12 in the control cylinder 1 rotates, it drives the docking rotating teeth 5 to rotate, and the docking of the two docking rotating teeth 5 is used to drive the control pipeline 12 in the docking cylinder 2 to rotate, thereby increasing the number of control devices, and when it is necessary to synchronize a single hydraulic delivery pipe, the docking pipe 8 can be used to dock the docking pipe joint 7 between the control cylinder 1 and the docking cylinder 2, or the docking pipe joints 7 between multiple docking cylinders 2 can be docked, so that the control cylinder 1 and multiple docking cylinders 2 are internally connected to realize the hydraulic delivery of a single hydraulic delivery pipe.
