Abstract

PURPOSE:To prevent the damage of the onion bulb and maintain the quality by placing a guiding device between the lower part of a leaf and stalk pull-up device and a leaf and stalk cutting device and guiding an onion backwards with the guiding device while restricting the pull out of the onion before cutting the leaf and stalk. CONSTITUTION:Lodged leaf and stalk of an onion on a field are clamped with a circulated lifting lug 5 and successively pulled upward. The leaf and stalk are stretched to nearly straightened state by the lifting lug 5 according to the forward motion of the machine body 6 and subjected to the action to be pulled out upward by the stretching action. In the above step, the top of the bulb of the onion is pressed with a guiding device 4 from the left and right sides above the bulb to prevent the pull-out of the bulb and guide the onion backward. The leaf and stalk of the onion are cut off with a leaf and stalk cutting device 2, the bulb is dug out with a digging edge 3 according to the forward motion of the machine body 6 and the harvested onion is transferred backward on a conveyor 7.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an onion guide device in an onion harvester.

C. Prior Art] A conventional onion harvesting machine of this type is configured to first dig up onions from a field and then cut off the leaves and stems during the transportation process.

Therefore, in this conventional type, it is necessary to align the directions of the leaves and stems in a constant manner during the transportation process after digging, which has the drawback of applying excessive force to the onions and causing damage.

[Problem that the invention seeks to solve]

The purpose of this invention is to greatly improve the conventional device. Before harvesting, the leaves and stems of onions are cut and then harvested.

To this end, while the onions are planted in the field, the leaves and stalks of the onions are stretched upward by a leaf and stalk pulling device, and the stretched portions are cut by a subsequent leaf and stalk cutting device. At this time, depending on soil conditions, leaf and stem conditions, etc., some onions are lifted up by the rug and pulled out of the field, and the pulp of some onions is damaged by the subsequent cutting device.

By using the technical means described below, this invention
This prevents the leaves and stems from being pulled out as they are pulled up, eliminates damage to the pulp of onions, and maintains quality.

[Means to solve the problem]

The present invention uses the following technical means to achieve the above object.

That is, a leaf and stalk cutting bag [2 for cutting onion leaves and stalks is provided behind the leaf and stalk pulling device 1, and an onion digging blade 3 is provided below and behind the leaf and stalk cutting bag &t2 to remove the leaves and stalks from the onion. This onion guide device for an onion harvester is provided with a guide device 4 that guides the onions backward while restricting the onions from being pulled out before cutting the leaves and stems from below the pulling device 1 and between the leaf and stem cutting device 2.

[Action/Effect]

The onions in the field are held by the rotating lifting lugs 5, which catch the leaves and stems of the onions, which have fallen down, and are successively pulled upwards. As the machine body 6 moves forward, the leaves and stems of the onion are stretched by the pulling lug 5, and the onion approaches a straight line, but along with this stretching action, the onion is also subjected to an upward pulling action. .

At this time, the guide device 4 acts to press down the upper part of the pulp part of the onion from the upper left and right sides, thereby preventing the onion from being pulled upward and guiding it backward.

Then, the leaves and stems of the onion are cut by the leaf and stem cutting bag kt2, and as the machine body 6 moves forward, the onions are dug up by the digging blade 3 and conveyed backward on the conveyor 7.

As mentioned above, this invention has a structure in which the leaves and stems are cut in advance when planted in the field and then harvested by digging, so the leaves and stems are cut after digging and harvesting. Compared to this, there is less excessive force applied to the pulp during the transportation process, which has the effect of preventing damage.

Moreover, this invention provides a guide device from the lifting process of the leaves and stems to the cutting, thereby preventing the onion from being pulled out due to the lifting action (stretching action of the leaves and stems), thereby preventing damage to the pulp. It has the characteristic that it can be harvested without any drying.

〔Example〕

The body 6 has a plurality of left and right pairs of leaf and stem pulling devices 1 each having a lifting lug 5 from the front, and a leaf and stem cutting device 2 is provided at the rear thereof and positioned below.

The guide device 4 is provided between the pair of left and right sides at an interval that can guide the onion's leaf and stalk from below the starting end of the leaf and stalk pulling device l to the rear through the bottom of the leaf and stalk cutting device 2. There is.

Therefore, this guide device 4 is configured to be able to guide the onion backward while preventing it from being pulled upward.

3 indicates a horitori blade, and 7 indicates a conveyor.

Reference numeral 8 denotes a leaf and stem discharge conveyor, which conveys cut leaves and stems to one side of the machine body 6 and discharges them.

With the above structure, it is possible to prevent onions from being pulled out during the period from when the leaves and stems are pulled up to when the leaves and stems are cut, and it is possible to harvest the onions with as little damage as possible.
