Rear wheel track setting system for three-wheel high-frame field operation vehicle

Abstract

The invention discloses a rear wheel track setting system for a three-wheel high-frame field operation vehicle. The rear wheel track setting system for the three-wheel high-frame field operation vehicle comprises a rear wheel supporting transverse beam arranged on the frame of the three-wheel high-frame field operation vehicle and rotating arm supporting seats fixed to the two ends of the rear wheel supporting transverse beam, wherein the rotating arm supporting seats are respectively hinged to the tops of corresponding rear wheel supporting arms through rotating arms respectively, and limit pull rods are respectively hinged between the two rotating arm supporting seats and the corresponding rear wheel supporting arms. Rotating arm pull rods are respectively hinged between the two rotating arms and the corresponding rear wheel supporting arms. The rear wheel supporting transverse beam is hinged to two wheel track adjusting hydraulic cylinders, piston rods of the two wheel track adjusting hydraulic cylinders are hinged to the corresponding rotating arms or the corresponding rear wheel supporting arms respectively, and the two wheel track adjusting hydraulic cylinders are communicated with a work hydraulic pump through a synchronous shunting motor and a hydraulic control valve which are connected in parallel respectively. Power output shafts of two rear wheel hydraulic motors are fixedly connected with corresponding rear wheel hubs respectively. The rear wheel track setting system for the three-wheel high-frame field operation vehicle has the advantages of meeting the requirements for mechanization operation of high stalk crops of different line spaces.

Description

technical field [0001] The invention relates to a self-propelled three-wheel elevated field operation, in particular to a rear wheel track adjustment system of a three-wheel elevated field operation vehicle. Background technique [0002] The mechanization of field management of 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, high-stalk crop sprayers, and the like. However, most of these machines are single-wheel and two-wheel walk-behind, with low work efficiency, poor stability, and high labor intensity; while three-wheel or four-wheel field vehicles are mostly in the form of mechanical transmission, which not only has frame design and driving system The structure is complex, the safety factor is low, the reliability and applicability are poor, and the price is high. Moreover, the track of the t...

However, most of these machines are single-wheel and two-wheel walk-behind, with low work efficiency, poor stability, and high labor intensity; while three-wheel or four-wheel field vehicles are mostly in the form of mechanical transmission, which not only has frame design and driving system The structure is complex, the safety factor is low, the reliability and applicability are poor, and the price is high. Moreover, the track of the two rear wheels of most vehicles cannot be adjusted, so it cannot be applied to the field management of high-stalk crops with different row spacings, and it is also not conducive to field management.
