Three-wheel fully hydraulic drive high-frame field operation vehicle

Abstract

The invention discloses a three-wheel fully hydraulic drive high-frame field operation vehicle which comprises a rack, a power system arranged on the rack, a three-wheel hydraulic driving mechanism driven through the power system, a front wheel steering mechanism and a wheel track adjusting mechanism. The rack comprises a horizontal rack, a cab supporting frame fixed to the front portion of the horizontal rack, a vertical rack fixed to the rear portion of the horizontal rack and a transverse beam fixed to the top of the vertical rack. The three-wheel hydraulic driving mechanism comprises a front wheel steering supporting arm and two rear wheel supporting arms. The front wheel steering mechanism comprises a steering wheel and a hydraulic steering gear. The wheel track adjusting mechanism comprises rotating arm supporting seats fixed to the two ends of the transverse beam, and limit pull rods are hinged between the rotating arm supporting seats and the corresponding rear wheel supporting arms. The power system comprises a fuel engine, a cooling fan, a hydraulic oil tank and a fuel tank. The three-wheel fully hydraulic drive high-frame field operation vehicle is designed for field operation of high stalk crops, trafficability and dynamic property are good, and the field management requirements of corn, tobacco, sugarcane and other high stalk crops of different planting line spaces are met.

Description

technical field [0001] The invention relates to a self-propelled field operation vehicle, in particular to a three-wheel full hydraulic drive field elevated operation vehicle. Background technique [0002] Field management machinery for high-stalk crops such as corn, tobacco, and sugarcane is an important part of the development of agricultural mechanization technology. At present, field operation machines for high-stalk crops include walk-behind micro-tillers, sprayers for high-stalk crops, etc., but these machines are mostly single-wheel and two-wheel walk-behind, and labor-intensive; while three-wheel or four-wheel The mechanical transmission form has problems such as simple frame design and driving system structure, low safety factor, poor reliability and applicability, and high price, and the wheel base of most field operations cannot be adjusted, so it cannot be applied to the field management of tall crops with different row spacings. Therefore, for the field managem...

Problems solved by technology

At present, field operation machines for high-stalk crops include walk-behind micro-tillers, sprayers for high-stalk crops, etc., but these machines are mostly single-wheel and two-wheel walk-behind, and labor-intensive; while three-wheel or four-wheel The mechanical transmission form has problems such as simple frame design and driving system structure, low safety factor, poor reliability and applicability, and high price, and most of the wheel bases for field operations cannot be adjusted, making it unsuitable for field management operations of high-stalk crops with different row spacings

Therefore, for the field management of high-stalk crops such as corn, tobacco, sugar cane, etc., there is an urgent need for a field elevated three-wheel vehicle with convenient operation, reasonable structure, and adjustable wheelbase, but there are no relevant reports yet.
