Description

Technical Field

[0001] The utility model relates to the technical field of sprayer driving, in particular to a single-wheel driving travel motor and a multi-wheel differential lock device for a sprayer. Background Art

[0002] The single-wheel drive travel motor of a sprayer usually refers to the motor used to drive a single wheel on the sprayer. This design is common on some small or medium-sized sprayers. It can provide enough driving force to push the machine to work in the field. When the motor is used to power the wheel, the motor is prone to slipping, causing the wheel to roll over.

[0003] After the motor has been running for a long time, the connection between the motor and the wheel will be worn due to long-term use. After wear, the connection will slip with the wheel, causing the four wheels to rotate out of sync and causing the sprayer to roll over. Therefore, a single-wheel drive travel motor and a multi-wheel differential lock device for a sprayer are proposed to address the above problems. Utility Model Content
