Green Chinese onion harvester

Abstract

The invention claims a green Chinese onion harvester, which comprises a stander, an hanging frame, a lifting frame, a green Chinese onion digging knife and a transmission mechanism. The transmission mechanism comprises a power input shaft and a gearbox which are connected in transmission way; the green Chinese onion harvester is characterized in that: a green Chinese onion pulling-out device is arranged below the stander for pulling out the green Chinese onion, delivering backwards and changing the green Chinese onion from longitudinal direction to transverse direction during delivery; a soilcleaning device is arranged below the green Chinese onion pulling-out device, and the rear side of the green Chinese onion pulling-out device is provided with an arc tray with an upward opening; a support plate is arranged between the soil cleaning device and the arc tray, and a pressing device is arranged above the arc tray. The green Chinese onion harvester realizes the mechanization of the whole process from digging green Chinese onion, pulling out green Chinese onion, cleaning soil to putting the green Chinese onion, thereby greatly reducing the labor intensity, improving the working efficiency, and obviously reducing the phenomenon of easily breaking the green Chinese onion during manual harvesting.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a green onion harvester. Background technique [0002] With the continuous improvement of varieties and the increasing export volume, scallions have become an important economic crop in some parts of northern my country. However, as the scallions grow longer and the height of the scallions becomes higher and higher, it becomes more and more difficult to harvest scallions. At present, the harvesting of scallions is done by the traditional manual method, that is, using a shovel to turn the soil on one side of the scallion ridge outward, hollowing out the side of the root of the scallion to expose the white of the scallion, and then gently pulling it out by hand, which is labor-intensive. The production efficiency is low, and a large amount of manpower needs to be invested in the harvest season. [0003] At present, there is a semi-mechanized green onion harvester on the mark...

At present, the harvesting of scallions is done by the traditional manual method, that is, using a shovel to turn the soil on one side of the scallion ridge outward, hollowing out the side of the root of the scallion to expose the white of the scallion, and then gently pulling it out by hand, which is labor-intensive. The production efficiency is low, and a large amount of manpower is required in the harvest season

[0003] At present, there is a semi-mechanized green onion harvester on the market. It is powered by an agricultural walking tractor, drives a digging knife to dig loose the soil on one side of the green onion, and then manually pulls the green onion out of the soil. The laborious excavation process has been eliminated, but the operation efficiency is still very low
