Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly relates to an electric agricultural tiller. Background Art

[0002] Agricultural mechanization refers to a modern production method that uses mechanical equipment for agricultural production. With the continuous progress of technology and the increasing demand for agricultural production, agricultural mechanization has become an important means to improve agricultural production efficiency, reduce labor intensity, and ensure food security. Agricultural mechanization can greatly improve agricultural production efficiency, reduce the waste of labor resources, and thus achieve the rapid development of agricultural production.

[0003] For example, an electric agricultural tiller with the authorization announcement number "CN216873747U", the traction motor and the tilling motor are independent of each other and each serves as an independent power source. In this way, an appropriate motor can be selected according to needs, thereby reducing the energy consumption loss during the intermediate transmission process and improving the battery usage efficiency. However, the traction vehicle of this device usually works in mountainous areas. After the battery runs out during operation, since there are no equipment and conditions for charging the battery unit in mountainous areas, it is necessary to replace the spare battery unit. At the same time, it is rather inconvenient to disassemble the battery unit of this device, which reduces the working efficiency of this device. The spacing between the tilling parts of this device is fixed and cannot be adjusted to suit different tilling width requirements, increasing the working limitations of this device.
