For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Reference Figures 1 to 2 This utility model provides a novel integrated multi-contact structure, including an integrated unit 1, a hydraulic cylinder unit 2, an oil circuit unit 3, and an on / off control unit 4. Several hydraulic cylinder units 2 are connected to the integrated unit 1, the oil circuit unit 3 is located inside the integrated unit 1, and an on / off control unit 4 is provided on the connection path between each hydraulic cylinder unit 2 and the oil circuit unit 3.

[0028] All the individual cylinders 2 can be integrated on the integrated unit 1, and by setting the oil circuit unit 3 inside the integrated unit 1, the complex oil pipe structure can be eliminated, making it more aesthetically pleasing;

[0029] Furthermore, by setting up an on / off control unit 4 on the connection path between each hydraulic cylinder unit 2 and the hydraulic circuit unit 3, the on / off control unit 4 can independently control its corresponding hydraulic cylinder unit 2 without affecting the overall hydraulic circuit of the hydraulic circuit unit 3, thereby achieving fine control of the hydraulic cylinder unit 2, and thus more accurately controlling all hydraulic cylinder units 2, and making fine selection and use according to actual needs during actual operation.

[0030] As an optional implementation, the oil circuit unit 3 includes a plug cavity oil inlet oil circuit 31 and a rod cavity oil inlet oil circuit 32. Each cylinder unit 2 is connected to the plug cavity oil inlet oil circuit 31 and the rod cavity oil inlet oil circuit 32 respectively. A switch control unit 4 is provided on the connection path between each cylinder unit 2 and the plug cavity oil inlet oil circuit 31.

[0031] As an optional implementation, the plug cavity oil inlet passage 31 includes at least one plug cavity branch passage. The specific number and arrangement of the plug cavity branch passages can be flexibly selected and set according to actual needs, and no specific restrictions are made in this embodiment.

[0032] When there is only one branch oil passage in the plug cavity, the branch oil passage in the plug cavity is connected to all the cylinder units 2;

[0033] When there are multiple branch oil passages in the plug cavity, each branch oil passage in the plug cavity is connected to at least one cylinder unit 2;

[0034] The rod cavity oil inlet passage 32 includes at least one rod cavity branch oil passage. The specific number and arrangement of the rod cavity branch oil passages can be flexibly selected and set according to actual needs. No specific restrictions are made in this embodiment.

[0035] When there is only one rod cavity branch oil passage, the rod cavity branch oil passage is connected to all cylinder units 2;

[0036] When there are multiple rod cavity branch oil passages, each rod cavity branch oil passage is connected to at least one hydraulic cylinder unit 2.

[0037] Based on this, by selecting the specific number and arrangement of the plug cavity branch oil circuits, and by selecting the specific number and arrangement of the rod cavity branch oil circuits, all cylinder unit 2 oil circuits can have a variety of oil circuit arrangement methods. With the assistance of the on / off control unit 4, all cylinder unit 2 can be uniformly and precisely controlled, so that cylinder unit 2 in different positions can be selected for actual compaction operations according to different usage requirements.

[0038] As an optional implementation, the on / off control unit 4 is a two-way solenoid valve. The two-way solenoid valve is a step-by-step direct pilot fluid control device, mainly used for the on / off control of compressed air, water and low-viscosity oil media. Therefore, it can be applied to this embodiment, and can independently control its corresponding hydraulic cylinder 2 without affecting the overall oil circuit of the oil circuit unit 3.

[0039] As an optional implementation, all the hydraulic cylinder units 2 are arranged in an array. The array arrangement makes the hydraulic cylinder units 2 more evenly distributed, thereby forming a uniformly distributed multi-contact head that covers the entire compaction operation area. With the assistance of the reasonably arranged hydraulic circuit units 3, various compaction operations can be effectively completed.

[0040] As an optional implementation, the cylinder unit 2 is provided with a plug cavity oil port. By providing a dedicated plug cavity oil port, the plug cavity oil port can be connected to the plug cavity oil inlet oil passage 31, and an on / off control unit 4 is provided on the connection path. The dedicated plug cavity oil port can improve the performance and extend the service life.

[0041] As an optional implementation, the cylinder unit 2 is provided with a rod cavity oil port. By providing a dedicated rod cavity oil port, the rod cavity oil port can be connected to the rod cavity oil inlet passage 32. The dedicated rod cavity oil port can improve the performance and extend the service life.

[0042] As an optional implementation, the integrated unit 1 is preferably a combination structure of an integrated plate and a compaction plate. The integrated plate and the compaction plate are connected. The top of each hydraulic cylinder unit 2 is connected to the integrated plate, and the bottom of each hydraulic cylinder unit 2 extends out of the compaction plate and can move relative to the compaction plate to perform compaction operations. The combination structure of the integrated plate and the compaction plate is a relatively conventional prior art, so it will not be described in further detail and is not shown in detail in the accompanying drawings.

[0043] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
