[0002] With the continuous improvement of the level of agricultural mechanization, as one of the important tools in agricultural production, lawn mowers play an important role in improving work efficiency and reducing the labor burden. Existing lawn mowers usually have a fixed structure and grass discharging mode, and it is difficult to meet the requirements of different working environments. For example, in some cases where it is necessary to evenly spread the forage on the ground, traditional lawn mowers often cannot achieve this goal well; while in the case of collecting forage, waste may be caused due to the scattering of forage.

[0003] In order to meet the needs of different scenarios, some lawn mowers with adjustable grass discharging modes have emerged on the market, but most of these lawn mowers have problems such as complex structures and inconvenient operations, and there are still deficiencies in adaptability. Therefore, developing a lawn mower with a simple structure, easy to operate and capable of effectively adjusting the grass discharging mode is of great significance for improving agricultural production efficiency. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a lawn mower with an adjustable grass discharging mode to solve the problems in the background art.

One side of the top of the machine cover is fixedly connected with an upper guide rail through a connecting piece. A suspension connecting plate is fixedly installed on the upper guide rail. The other side of the top of the machine cover is fixedly connected with a lower guide rail through a connecting piece. A suspension is fixedly installed on the lower guide rail, and one end of the suspension connecting plate is fixedly connected to one side of the suspension. The tail of the machine cover is provided with an inner rear baffle, and the tail end of the inner rear baffle is provided with an outer rear baffle.

[0006] Preferably: A gearbox for docking with a tractor is fixedly installed on the top of the machine cover, and a drive shaft tube assembly is installed at the output end of the gearbox, and the drive shaft tube assembly penetrates through one side of the machine cover.

[0007] Preferably: A pulley assembly is arranged on the outer wall of the machine cover, and the pulley assembly is installed at one end of the drive shaft tube assembly.

[0008] Preferably: A cutter shaft rotatably connected to the inner wall of the machine cover and penetrating to the position of the pulley assembly is provided, and the pulley assembly is installed at one end of the cutter shaft.

[0039] It should be noted that the slide rail plates 10 are fixedly connected to both sides of the bottom of the hood 6 and are used to improve the stability of the mower on the ground and reduce friction.

[0040] Working principle: When the tractor drives the mower forward, the tractor provides power for the mower by docking with the transmission 9. The transmission 9 converts the power of the tractor into the rotational speed and torque suitable for the mower. The converted power is transmitted to the pulley assembly 5 through the drive shaft tube assembly 4. The pulley assembly 5 then transmits the power to the cutter shaft 12 through a belt. The cutter shaft 12 starts to rotate after receiving the power. The blades 13 fixed on the cutter shaft 12 rotate together with the cutter shaft 12 to cut the forage. The cut forage moves downward due to the airflow generated by the rotation of the cutter shaft 12 and its own gravity. The cut forage passes through the space inside the hood 6 and is guided by the inner rear baffle 14. The inner rear baffle 14 helps control the direction of the forage flow and makes it move towards the tail of the hood 6. Under the action of the outer rear baffle 7, the forage is guided to a specific position or directly discharged from the hood 6. The suspension 1 and the suspension connecting plate 2 ensure a stable connection between the mower and the tractor. The upper guide rail 3 and the lower guide rail 11 provide necessary support points for the suspension 1.
