Hydraulic transmission for the grass seeds planting machine

The grass seeds planting machine generally consists of two transmission modes, mechanical transmission and hydraulic transmission. Mechanical transmission is a relatively long-lasting and versatile transmission method. It adopts a chain to drive the stirring shaft to stir and complete the spraying.
The structure is simple, easy to maintain, and the operation is universal. The hydraulic transmission is a new type of transmission, driven by a hydraulic motor. The hydraulic oil pump realizes the stirring and spraying of the guest soil spraying machine, which is light and flexible, small in size, and does not have the common failure of mechanical stirring in the high-speed rotation of the machine. The specific advantages of hydraulic transmission are as follows:
1. Under the same power conditions, the hydraulic transmission is small in size, light in weight and compact in structure (for example, the weight of the hydraulic motor is only 15%-20% of the weight of the same power motor). Therefore, its inertia has a small commutation frequency. When the hydraulic drive adopts high pressure, it can output large thrust or large torque. Low-speed large-tonnage transmission can be realized, which is an outstanding advantage that mechanical transmission cannot compare.
2. The hydraulic transmission can easily realize the steeples speed regulation in the system operation process in a large range, and the mechanical transmission realizes the steeples speed regulation.
3. Pipe joints and integrated block connections are used between hydraulic components. Its layout is installed with great flexibility and convenience.
4. The hydraulic transmission can perform the movement of the original to make the load evenly stable when the load changes, and reduce the commutation impact when the moving parts are reversed.
5. The hydraulic transmission system is easy to operate and convenient to adjust and control.
6. The hydraulic transmission system is easy to realize overload protection. It is safe and reliable to use. The moving parts in each hydraulic original are working in the oil and can be self-lubricated, so the service life is long.
