Ground profiling mechanism of vegetable harvester

Abstract

The invention relates to a ground profiling mechanism of a vegetable harvester. The ground profiling mechanism is characterized in that an electric push rod support is mounted in the middle of a rotary shaft, a sensor support and a sensor are mounted on the rotary shaft part on each of the two sides of the support, and each sensor support is hinged to a first rotary arm and a second rotary arm and connected with a rotary arm connecting rack to form a parallelogram mechanism; the front end of a touch rod support on each of the two sides is provided with a left touch rod and a right touch rod, the touch rods contacts with the ground, each touch rod support is mounted at the front end of the corresponding rotary arm connecting rack, and a sensing plate is mounted at the rear end of each rotary arm connecting rack; one end of an adjusting screw is connected with the electric push rod support, and the other end of the adjusting screw is connected with an electric push rod. When the touch rods contact with the ground and have displacement, the sensors sends signals to a controller, and the controller can control the cutting height between a cutting platform and a field surface. The ground profiling mechanism has the advantages that the front-rear and leaf-right horizontal positions between the cutting platform and the field surface can be regulated in real time according to the surface relief of the ground, and high-quality and efficient leaf vegetable harvesting is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural harvesting equipment, in particular to a ground profiling mechanism of a vegetable harvester. Background technique [0002] 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, the vegetable harvester has become a hot spot in the current agricultural machinery research. [0003] At present, the research on related vegetable harvesters has made great progress, but the existing simple vegetable harvesters do not have a ground height adjustment device. When the flatness of the vegetable bed surface is poor, the machine cannot automatically adjust the position of the header, resulting in poor harvest quality of leafy vegetables ; and the ground p...

Problems solved by technology

[0003] At present, the research on related vegetable harvesters has made great progress, but the existing simple vegetable harvesters do not have a ground height adjustment device. When the flatness of the vegetable bed surface is poor, the machine cannot automatically adjust the position of the header, resulting in poor harvest quality of leafy vegetables ; and the ground position height adjustment device used by vegetable harvesters with a high degree of automation can only adjust the position of the header according to the height of the vegetable bed surface in the forward direction of the harvester, ignoring the left and right heights of the vegetable bed surface, which affects the quality and quality of the leafy vegetables. cause loss

[0004] In view of this, according to the harvesting characteristics of leafy vegetables, technicians in this field are committed to developing a vegetable harvester profiling mechanism device suitable for adjusting the surface position of the vegetable border to solve the unevenness of the surface of the vegetable border and the height of the left and right sides. The technical problem of not being able to harvest vegetables accurately and the contact between the cutter and the soil is easy to damage the cutter
