Description

Technical Field

[0001] The utility model relates to the technical field of lawn mowers, in particular to a lawn mower with side grass discharge. Background Art

[0002] When traditional lawn mowers cut grass, the cut grass is usually processed by directly discharging it downward or collecting it through a grass collection bag. This method has some disadvantages. For example, the grass collection bag needs to be frequently cleaned, is prone to blockage, and affects work efficiency; when directly discharging downward, the grass may accumulate under the lawn mower, affecting the subsequent cutting effect.

[0003] To overcome these deficiencies, some improved lawn mowers have emerged in the prior art, and they adopt different structures to improve the grass discharge method. For example, some lawn mowers adopt a side discharge design, which can avoid the problem of grass accumulation. However, such lawn mowers still have some problems in actual use, such as uneven discharge and easy blockage of grass. Summary of the Utility Model

[0039] Working principle: First, power is input into the transmission 7 by a tractor or other power source through the PTO shaft 71. The transmission 7 converts the input power into a rotational speed and torque suitable for use by the lawn mower. The drive shaft assembly 6 receives power from the transmission 7 and transmits it to the driven wheel 131 through the driving wheel 61. The driving wheel 61 and the driven wheel 131 are connected by a belt to achieve power transmission to the cutter shaft 13. The blades 12 on the cutter shaft 13 rotate at high speed with the transmission of power to complete the cutting of the forage. The hydraulic motor 2 drives the drum 14 to rotate through a transmission mechanism. Among them, the transmission gear 21 is connected to the output end of the hydraulic motor 2, and the driven gear 22 is connected to one end of the drum 14, and power transmission is achieved through the chain 23.

Suspension 8: fixedly connected to one side of the top of the hood 1, which is used to suspend the lawn mower on a tractor or other towing equipment.

[0040] When the lawn mower is started, the PTO shaft 71 starts to rotate, and power is transmitted into the transmission 7. After the transmission 7 adjusts the rotational speed and torque, it is transmitted to the cutter shaft 13 through the drive shaft assembly 6. The blades 12 on the cutter shaft 13 rotate at high speed to cut the forage. At the same time, the hydraulic motor 2 drives the drum 14 to rotate through a transmission mechanism, and the drum 14 drives the spiral shaft 15 to rotate, pushing the cut forage to one side of the hood 1. The grass guard chain 10 ensures that the forage can be discharged smoothly without jamming the machine.
