Lawn mower

Abstract

The invention discloses a lawn mower. The lawn mower comprises a rack system, a walking system, a power system, an operation system and an electric appliance control system, and further comprises a header system. The walking system is assembled on the rack system to achieve advancing or retreating or turning of the lawn mower. The power system provides a power source for the whole lawn mower. The operation system is assembled on the rack system to control the walking and mowing of the lawn mower. The electric appliance control system is controlled by the operation system to control the walking and mowing action of the lawn mower. The header system is arranged on the front part of the whole lawn mower to achieve the mowing function. In this way, a lithium battery is adopted as the power source, two direct-current brushless motors are adopted to achieve independent walking and mowing work, noise is reduced, maintenance cost is low, the control accuracy, namely, the safety logic protection, is guaranteed through a direct-current motor controller, zero-emission and zero-pollution are achieved through an electric driving mode, and the true sense of environmental friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of garden tools, in particular to a lawnmower. Background technique [0002] At present, most lawn tractors on the market are driven by gasoline engines, and the output shaft of the gasoline engines is placed vertically. After the gear is decelerated, the wheel is driven forward or backward; on the other hand, an electromagnetic clutch is installed on the output shaft of the engine, and the power is transmitted from the pulley of the electromagnetic clutch to the pulley installed on a certain cutter shaft after three-stage belt transmission, and then by the synchronous The belt (to ensure that all cutters rotate at the same speed) drives the rest of the cutters to work. Its disadvantages are: [0003] 1. When the gasoline engine is working, the vibration generated by the engine is relatively large, which causes the vibration of the tractor to be relatively large, and the noise is correspondingly relatively...

AI Technical Summary

Problems solved by technology

[0003] 1. When the gasoline engine is working, the vibration generated by the engine is relatively large, which causes the vibration of the tractor to be relatively large, and the noise is correspondingly relatively large, and the noise and vibration will bring physical discomfort to the operator;

[0004] 2. This structure uses a large number of belt drives. The mechanical structure is complex and the transmission efficiency is low. The belt needs to be replaced regularly as a wearing part. At the same time, the vibration generated by the gasoline engine will also cause the transmission belt to vibrate, which will easily cause the belt to wear out in advance and increase Reduced maintenance costs for users;

[0005] 3. Gasoline engine emissions will pollute the atmosphere;

[0006] 4. The cost of gasoline engine use and maintenance is relatively high

[0007] At present, EPA regulations are strict and the threshold is getting higher and higher. To meet the regulations and standards will increase the cost
