A longitudinal conveying device of a fully automatic crawler-type green onion harvester

Abstract

The invention discloses a longitudinal conveying device of a full-automatic crawler-type green Chinese onion harvester. The longitudinal conveying device comprises two conveying units, wherein each conveying unit comprises a connecting portion for positioning and installation with a rack, a framework located at the connecting portion and arranged in the green Chinese onion transfer direction, a driving wheel, a driven wheel, annular belts arranged on the driving wheel and the driven wheel in a sleeving mode and a tensioning mechanism arranged on the framework and used for propping the annular belts open from inside to outside and tensioning the belts, wherein the driving wheel and the driven wheel are arranged at two ends of the framework, the axes of the driving wheel and the driven wheel are perpendicular to the framework, the annular belts are sponge belts, the side edges, outwards propped open by the tensioning mechanism, of the two sponge belts attach to form a green Chinese onion clamping region, and green Chinese onions are vertically arranged in the green Chinese onion clamping region. The longitudinal conveying device can make green Chinese onions vertical, perform conveying in the mode that the bottom is suspended and accordingly facilitates the work of root soil removal of the green Chinese onions. In addition, the arranged sponge belts and tensioning mechanism make the green Chinese onions not damaged in the conveying process, and the quality of harvested green Chinese onions is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a longitudinal conveying device of a fully automatic crawler-type green onion harvester. 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 mach...

Problems solved by technology

[0005] 1) Although the feeding manipulator is used, due to the different thickness of the scallions themselves, the manipulator is easy to break or damage the scallions during the clamping process, resulting in low quality of the scallions harvested;

[0006] 2) The chain conveyor system directly supports the roots of the scallions, making it impossible to remove the soil. Not only does the soil in the conveyor system need to be cleaned after harvesting, but it also affects the later palletizing and packaging work, increasing transportation costs
