Hand-held island field material onion soil digging and discharging operation machine

Abstract

The invention provides a hand-held island field material green onion soil digging and discharging operation machine. The hand-held island field material green onion soil digging and discharging operation machine comprises a soil digging device, an auxiliary feeding device, a longitudinal conveying device, a soil screening and impurity removing device, a transverse conveying device, an engine, a handrail, a chassis walking device, a depth limiting guide wheel and a rack. The soil lifting device adopts a mode of loosening first and then digging, so that the driving resistance is reduced, and the soil lifting quality and the whole machine operation efficiency are improved; the auxiliary feeding device adopts a flexible grain pulling device, and the longitudinal conveying device can dynamically adjust the clamping force, so that the damage to the green onions is reduced; the soil screening and impurity removing device is used for preliminarily cleaning the green onions, so that the manual operation intensity is reduced; the transverse conveying device avoids bending damage caused by non-uniform length of the green onions conveyed in a longitudinally-arranged and vertically-lying mode. According to the green onion harvester, combined operation of digging soil and pulling seedlings, conveying and lifting, soil screening and impurity removing and orderly placing in the green onion harvesting process is achieved, the labor intensity of manual green onion harvesting is greatly reduced, and the harvesting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of vegetable harvesting machinery and equipment, and in particular relates to a hand-held Shimada material and onion excavation and discharge operation machine. Background technique [0002] Onion, belonging to Liliaceae Allium plant, also known as: shallot, green onion, onion, four seasons onion. As one of the important seasonings in China, spring onion has the functions of seasoning and deodorizing. At the same time, spring onion has extremely high medicinal value. It has a long history of cultivation and is widely distributed. In recent years, the consumption of onion in China has increased year by year, and the planting area has also continued to increase. Spring onion has been planted on a large scale in the northern Jiangsu region, especially in Xinghua City, Jiangsu Province. Due to the scarcity of land, low-lying terrain, and swaying lakes in the northern part of Jiangsu, the planting mode of onion is the is...

AI Technical Summary

Problems solved by technology

For the harvesting of shallots, a new type of shallot harvester is disclosed in the prior art, but the quality of shallots cannot be guaranteed if the damage is large

[0004] Although many harvesting machines have been developed for the harvesting of vegetables, in the process of mechanized vegetable harvesting, there are many kinds of vegetables, and there are great differences in their geometric shapes and physical characteristics.

Therefore, other vegetable harvesters cannot meet Shimada's requirements for efficient harvesting of shallots

In addition, although the structure of green onions is similar to green onions, the root system of green onions under the Shimada planting model is shallow, the growth height is small, the soil texture is sandy loam, and the pulling force required is different from that of green onions.

Therefore, the low-damage harvesting of shallots cannot be achieved by using the technology of pulling out seedlings of thicker stem and leaf vegetables such as scallions
