Background
The dynamic compactor is a machine for compacting and loosening soil in building engineering, and has the working principle that after a rammer is repeatedly lifted to a certain height, the rammer is put down, and the freely falling rammer compacts and loosens the soil. At present, three transmission devices of the dynamic compactor are provided, wherein one transmission device is pure mechanical transmission, one transmission device is pure hydraulic transmission, and the other transmission device is mechanical-hydraulic integrated transmission. Mechanical dynamic compaction machine: the hoisting, walking and rotating mechanisms of the mechanical fingers are all mechanical. The disadvantages are that: it is bulky, the dismouting is inconvenient, and the security is poor to be forbidden by a lot of building sites and get into, the advantage: the reliability is good. Hydraulic dynamic compaction machine: the hydraulic pressure refers to the hydraulic control of the hoisting, walking and rotating mechanisms. The disadvantages are as follows: the transmission efficiency is low, the failure rate is high, the maintenance difficulty is high, and the technical skill of maintenance personnel is high. The advantages are that: small volume and light weight. Machine-liquid integration: the hoisting of the mechanical finger is mechanical, the hydraulic finger walks and rotates, and the amplitude variation mechanism is hydraulically controlled. The advantages are that: the winch is mechanically driven, the efficiency is high, the failure rate is low, other actions (walking and rotating) are hydraulically driven, the size is small, and the weight is light.

Patent No. CN201410168149.0 discloses a mechanical-hydraulic integrated dynamic compactor, and the power transmission route of the scheme is as follows: engine, fluid coupling, transfer case, hydraulic pump and winch. The disadvantages are that: 1. the engine and the winch are transversely arranged in parallel, the operating platform is ultra-wide, the size is increased, the operating platform equipment is not compact in arrangement, the operating platform cannot meet the requirements of different operating platforms, and the operating platform is poor in reliability and stability in arrangement. 2. The engine is located the operating platform intermediate position, and the installation maintenance is very inconvenient. 3. The power of the engine is transmitted to the hydraulic pump and needs to pass through the hydraulic coupler, so that the transmission efficiency is reduced. 4. When the hydraulic pump and the winch work simultaneously, after the power of the engine passes through the hydraulic coupler, one part of the power is transmitted to the hydraulic pump, and the other part of the power is transmitted to the winch. When the dynamic compactor works, the engine power intermittently drives the winch to rotate, the engine is required to provide power when the winch rotates forwards, the engine is not required to provide power when the winch rotates backwards, and the winch drives the winch to rotate backwards by means of free falling of the rammer. Therefore, the torque transmitted to the hydraulic pump by the engine is high and low in time and is very unstable, so that the pressure fluctuation of a hydraulic system of the dynamic compactor is large. Therefore, the hydraulic pump and the winch can interfere with each other by the scheme, so that the pressure of the hydraulic system of the dynamic compactor is greatly fluctuated, and the hydraulic system of the dynamic compactor is damaged.
