Method for harvesting green Chinese onion

Abstract

The invention discloses a method for harvesting green Chinese onion. The method comprises the following steps: 1) while shoveling soil, forming two cutting slots by a soil-separating device; 2) backwardly moving the shoveled green Chinese onion, primarily removing the soil on the roots of the green Chinese onion by using a comb-shaped joint part and then leading a longitudinal conveying device; 3) vertically clamping the green Chinese onion in the longitudinal conveying device, using a soil-shaking device for shaking off the soil on the roots of the green Chinese onion in the conveying process, thereby realizing the secondary removing of the soil on the roots of the green Chinese onion; 4) after the soil is removed, moving the green Chinese onion from the longitudinal conveying device to the horizontal conveying device, and rotating the green Chinese onion through an inclined channel and gradually backward conveying; and 5) when the green Chinese onion is conveyed to the discharging end, correcting to the horizontal state by the guiding mechanism, thereby completing the secondary rotation, and then conveying to a stacking area and completing the packing. According to the method provided by the invention, the shoveling soil volume can be reduced, and meanwhile, the secondary removal for the soil on the roots of the green Chinese onion and the secondary rotation for the green Chinese onion are adopted, so that the stacking and packing operations can be conveniently performed.

Description

technical field [0001] The invention relates to a method for harvesting green onions. Background technique [0002] In view of the development trend of vegetable harvesting mechanization at home and abroad, especially for the current state of domestic vegetable (green onion) mechanized automatic harvesting equipment products in the market, on the basis of making full use of existing research and development, draw on both reference and independent innovation, theoretical and technological research Organic combination, focusing on research and development and optimization design around the intensive harvesting system of green onions, in order to improve the operation efficiency, degree of automation and quality of finished products of green onions harvesting in my country. And according to the "Made in China 2025" plan, in terms of agricultural machinery, it is proposed that by 2020, the core functional components and complete machine testing, testing, development and collabora...

AI Technical Summary

Problems solved by technology

[0005] 1) After excavating the soil, there is no corresponding soil shaking device, and the scallions and soil are transported together and then packed, which increases the cost of harvesting and transportation;

[0006] 2) Because scallions are generally planted one ridge by one ridge, there is no auxiliary equipment for dividing ridges, and the shoveling of scallions cannot be accurately realized. Therefore, it requires a large range of shoveling, resulting in the harvesting There is a lot of soil, which is not conducive to transportation. At the same time, it is easy to shovel the roots of the scallions during the process of shoveling, which brings great inconvenience to the harvest of scallions;

[0007] 3) Although the feeding manipulator is used, in the process of vertical and horizontal conversion, it is still impossible to accurately realize the horizontal and neat transportation and placement of green onions, which brings great inconvenience to the subsequent packaging work;

[0008] 4) Due to the different thickness of scallions, the manipulator is easy to break the scallions during the clamping process, resulting in low quality of scallions harvested
