Description

[Detailed description of the invention] This invention guides the harvested onions between a pair of rollers that rotate inwardly and in opposite directions, and draws the leaves and stems between the rollers while conveying them in the axial direction of the rollers. This invention relates to an onion harvesting machine that allows onions to hang down and cuts the hanging leaves and stems with a canter.

With this type of harvester, when cutting the hanging leaves and stems as described above, the length is relatively long compared to when they are shipped immediately after harvesting.
・When dividing the tree, it may be cut leaving the long leaves and stems intact.

This invention was tried keeping in mind the above actual situation,
It makes it possible to cut leaves and stems long, and to cut them short, and it is solid so that both cuts can be done smoothly and well. In the harvesting machine, a driving rotation shaft is disposed near the ends of both rollers, and guides are provided at the ends of both rollers to support the leaves and stems of onions from the left and right sides, and the The rotating shaft includes a first canter having an end edge having a length that acts near the lower surface near the end of the roller, and a second canter having an edge having a length higher than the lower surface of the roller with respect to the guide. A first state in which onions are supported near the end of the roller and cut with the first cutter near the lower surface of the roller; The structure can be switched to a second state in which the leaves and stems of onions are supported by guides from both the left and right sides at a position removed from the rollers, and are cut by a second canter at a position higher than the lower surfaces of both rollers. It is characterized by being

That is, in the first state, leaves and stems are cut with long leaves (
・Furthermore, in the second state, the leaves and stems can be cut short, and in the first state, the onions can be easily stabilized by the rotating action of the roller (from In the second state, the onions are no longer stably supported by the rollers, but because the leaves and stems are supported by the guide, they can be cut equally well. Became(・ru)

In other words, according to the present invention, if you always try to cut the onions by supporting them with a roller, the canter and roller will interfere, making it impossible to cut the leaves and stems short enough.
Moreover, when cutting the onions into short pieces, the onions are not supported by rollers (and therefore, the leaves and stems tend to become unstable), but by supporting them with guides and solving this problem, the first state In addition, in the second state, it became possible to cut uniformly and satisfactorily to the desired length.

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative drawings.

The figure shows an example of an onion harvester, which is equipped with a front pre-processing section, a rear post-processing section, a collection section, etc., and while traveling on a crawler traveling device 1, the pre-processing section operates as described below. It is configured to harvest the planted onions.

That is, the pre-treatment section is exposed to a certain extent in the field (onions are dug up by the blade 2, and the dug up onions are scraped backward by the scraping rotor 3). It is configured to be conveyed rearward by a slant-type gently inclined conveyor 4, and subsequently lifted and conveyed rearward and upward by a steeply inclined lifting conveyor 5 having a bagent-shaped receiving portion 5a. It is configured so that it is dropped and discharged from the terminal end of the conveying device 5 onto the post-processing section.

The post-processing section has a plurality of pairs of rotating rollers 6.6 each having a spiral protrusion on the circumferential surface arranged side by side, and transfers the onions delivered from the lifting and conveying device 5 to the inward direction of the rollers 6.6. As the leaf and stem rotate in the opposite direction, the leaf and stem are conveyed in the axial direction of the roller, and the leaf and stem are drawn between the two rollers and suspended, and the hanging leaf and stem are cut as described below.

In other words, as shown in Figure 2 A1 and Figure 3 A1,
A drive rotation shaft 7 is mounted on the terminal end of the roller 6,
A first cutter 8a and a second cutter 8b are attached to this rotating shaft 7.
and are configured to be attached interchangeably.

The first cutter 8a acts near the lower surface near the end of both the rollers 6.about.6 as shown in FIG. A first state occurs in which the leaves and stems are cut near the lower surfaces of both rollers 6.6 while supporting the onions near the ends of both rollers.

Further, the second canter 8b has a receiving portion 9a and a leaf stem for receiving and supporting onions placed successively at the terminal end of the roller 6. For the auxiliary members 9, 9 integrally formed with the guide 9b that supports the.

It is configured to engage at a position higher than the lower surface of both rollers 6.6.

Therefore, with the second canter 8b installed,
The onions are supported at a position removed from both the rollers 6.6, the Chinese leaves and stems are supported by the guides 9b, 9b from both left and right sides, and cut at a position higher than the lower surface of the rollers 6, 6. A second state appears.

Therefore, by selecting the first state and the second state, it is possible to cut the leaves and stems with different lengths, and the onions after cutting the leaves and stems are delivered to the next collecting section.

The collection section sends the onions delivered from the post-processing section to one side of the machine body on a conveyor 10, and
The conveyor 10 is configured to collect onions fed to the terminal end into a box-shaped container 12 while being guided by a omper 11.

Claims (1)

[Scope of utility model registration request] Harvested onions are guided between a pair of inwardly rotating rollers 6.6, and while conveyed in the axial direction of the rollers, the leaves and stems are drawn between both rollers and allowed to hang down. When cutting the stems with the cutters 8a and 8b, a driving rotation shaft 7 is disposed near the ends of the two rollers 6. Guides 9b and 9b are provided to support the stem from both the left and right sides, and the rotary shaft 7 has a first canter 8a with one edge having a length that acts near the lower surface near the end of the roller 6.6, and a first canter 8a with an end edge. A second cutter 8b that acts on the guides 9b and 9b at a position higher than the lower surface of the roller 6.6 is configured to be able to be attached alternately, so that A first state in which the onions are cut with the first canter 8a near the bottom surface of both rollers 6.6 while supporting the onions, and a first state in which the onions are cut with the first canter 8a near the bottom surface of both rollers 6.6, and the leaves and stems of the onions are cut at a position away from both the rollers 6.6. It is characterized by being configured so that it can be switched to a second state in which it is supported by guides 9b, 9b from both the left and right sides and cut by the second canter 8b at a position higher than the lower surface of both the rollers 6.6.
