Self-propelled electric green leafy vegetable harvesting machine

Abstract

The invention relates to a self-propelled electric green leafy vegetable harvesting machine which comprises a vehicle frame, a driving device, a header, travel chassis, a hydraulic lifting device, a ground profiling mechanism and a driving operation desk. Two side plates are mounted on two sides of a rear transverse beam, a front transverse beam is mounted at the fronts of the two side plates, a band saw cover is mounted on the tops of the two side plates, a band saw is mounted on a belt pulley to form a friction pair, the belt pulley can be driven by a band saw driving motor to rotationally move, and a reel can be driven by a reel driving motor to rotationally move. The header can ascend and descend under the effect of a hydraulic cylinder, and the levelness of the header and earth surfaces of field surfaces can be adjusted by the hydraulic cylinder according to sensor signals when the field surfaces are uneven. The header is obliquely mounted at the front end of the travel chassis via hinge pins, the hydraulic lifting device is mounted at the front end of the travel chassis, and the ground profiling mechanism is mounted at the bottom of a side plate at the front of a middle transverse beam. The self-propelled electric green leafy vegetable harvesting machine has the advantages that cutting heights between the band saw and the field surfaces can be adjusted, the header and the earth surfaces of the field surfaces can keep level, and the self-propelled electric green leafy vegetable harvesting machine is high in automation degree.

Description

technical field [0001] The invention belongs to the field of agricultural harvesting equipment, in particular to a self-propelled electric green leafy vegetable harvester. Background technique [0002] China is a big producer of green leafy vegetables, and green leafy vegetables account for 30%-40% of the total vegetable production. Harvesting operations account for about 40% of the total workload in green leafy vegetable production operations. Due to the complexity of vegetable harvesting, the current harvesting of green leafy vegetables in my country is mainly manual, with high labor intensity, labor shortage, and low level of mechanization have become the restrictive factors for the development of my country's green leafy vegetable industry. Therefore improve the efficiency, the quality of green leafy vegetable harvesting, reduce labor intensity, and invent and develop green leafy vegetable harvester has urgent practical significance.

Problems solved by technology

[0003] Chinese patent document CN205105648U discloses an electric leaf vegetable harvester, which uses a lithium battery as a power source to overcome the impact of exhaust gas on people and vegetables. Adverse effects, but the machine adopts a manual hand-held design, which is labor-intensive, low in automation, and slow in operating efficiency

[0004] Chinese patent document CN205902398U proposes a vegetable harvester, which uses an electric push rod to adjust the position of the header, and can adapt to the harvesting of leafy vegetables of different heights. When the flatness of the vegetable bed surface is poor, this machine cannot automatically adjust the position of the header, resulting in poor harvest quality and large losses of leafy vegetables

[0005] The deficiency of the above-mentioned prior art is: the adaptability of the simple vegetable harvester is relatively poor, and the height of the header cannot be automatically adjusted when the surface of the vegetable bed is poor. Affects the quality of vegetable harvesting; and vegetable harvesters with a high degree of automation mostly use internal combustion engines as power. Due to long-term operations in the facility, exhaust emissions affect human health and crop quality
