Problems solved by technology
[0002] At present, existing agricultural vehicles, especially tillers, use two-wheel or four-wheel steering. Two-wheel steering is not convenient for farmland operations due to its large steering radius; although four-wheel steering is convenient for farmland operations, it usually uses mechanical four-wheel steering. Steering system, the deflection of the rear wheels relies on mechanical transmission to transmit the deflection motion of the front wheels to the rear wheels
Due to the inevitable wear and tear of the mechanical part, the transmission gap increases, so that the actual deflection angle of the rear wheel is inaccurate and the performance decreases
The lifting and lowering of the rotary tiller assembly of the traditional tiller is often performed by purely manual mechanical operation, which requires a lot of effort

The invention discloses a four-wheel hydraulic steering mini-tiller. The four-wheel hydraulic steering mini-tiller comprises an engine, a gearbox, front wheels, rear wheels, a rack, a rotary blade assembly and a hydraulic system, wherein power is transmitted to the gearbox by the engine, and the rotary blade assembly is driven to rotate through a rotary tilling transmission component by the power output by the gearbox; the engine, the gearbox, the front wheels, the rear wheels and the rotary blade assembly are all arranged on the rack; the hydraulic system comprises a hydraulic power-assisted steering system and a rotary blade assembly hydraulic lifting system; the hydraulic power-assisted steering system comprises a steering control valve, an oil pump, an oil tank, a distributing valve, a front wheel steering power cylinder and a rear wheel steering power cylinder; the rotary blade assembly hydraulic lifting system comprises a rotary tilling lifting hydraulic cylinder and the rotary blade assembly. The four-wheel hydraulic steering mini-tiller disclosed by the invention has the advantages that the turning radius is small, the steering is portable and accurate, the operation is labor-saving, and the like.
Description
Technical field [0001] The invention relates to the field of agricultural operation vehicles, in particular to a four-wheel hydraulic steering micro-tiller. Background technique [0002] At present, the existing agricultural vehicles, especially the tillers, use two-wheel or four-wheel steering. The two-wheel steering is not convenient for farmland operations due to its large turning radius. Although four-wheel steering is convenient for farmland operations, it usually uses mechanical four-wheel steering. In the steering system, the deflection of the rear wheels relies on mechanical transmission to transmit the deflection movement of the front wheels to the rear wheels. As the mechanical parts are inevitably worn and the transmission gap increases, the actual deflection angle of the rear wheel is inaccurate and the performance decreases. The lifting and lowering of the rotary tiller assembly of the traditional micro-tiller is often purely manual mechanical operation, which requi...
