Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onion harvesting apparatus for treating leaf stems.

(Prior art)

Conventional onion harvesters of this kind are, for example,
As described in Japanese Patent Application Publication No. 019, harvesting is performed with the leaf stem attached, and the leaf stem is cut and removed in the transportation process after the harvest.

Further, Japanese Patent Publication No. Sho 62-37927 discloses a structure in which a leaf stem is cut and removed prior to harvesting an onion.

However, according to the former configuration, a special clamping and conveying device or the like is required to cut the leaf stem after harvesting, and there is a defect that the configuration is extremely complicated.

Further, with the latter configuration, there is a problem that the leaf stems cut off before harvesting are left as they are in the field scene, and the left leaf stems hinder the subsequent digging work.

[Problems to be solved by the invention]

If this type of onion harvester is configured to cut the onion leaf stem after excavation by the excavator, there is a problem that the transport device before and after cutting becomes complicated.

In addition, if the onion leaf stem before cutting was cut off, the cut leaf stem was scattered on the field scene, which made post-treatment difficult.

Another problem is that onions are cultivated by transplanting two onions to one ridge.

For this reason, two onions that are planted at the same time are surely grown with the spacing between them being constant, but the gap between two rows of one row is not constant and it is extremely difficult to harvest at the same time. Often.

[Means for solving the problem]

The present invention employs the following technical means to solve the above-mentioned problems. That is, first, the first invention includes a pair of inclined leaf raising devices 3 and 3 ′ each having an inclined front end having a forward end at a front lower portion and an end portion having a rear upper end at a front portion of a chassis 2 having a traveling device 1. The leaf stem raising devices 3 and 3 'are provided with the raising passages 5 facing the raising lugs 4 on both sides facing each other at a high position in a C-shape when viewed from the front, and are provided below the leaf stem raising devices 3 and 3'. A leaf cutting device 6 is provided in close proximity to the raising passage 5, and the rear end of the leaf cutting device 6 faces a starting end of a leaf transporting device for transporting the cutting leaf from the middle portion of the chassis 2 to the rear. This is a leaf stem treatment device provided with an onion harvester.

Next, the second invention is a chassis 2 having a traveling device 1.
A pair of leaf stem raising devices 3 and 3 'are provided at the front portion of the pair of slanting portions, with a starting end portion being forwardly downward and an end portion being upwardly rearward, and a pair of leaves below the leaf stem raising devices 3 and 3'. A leaf cutting device 6 is provided in close proximity to the raising passage 5 formed by the stem raising devices 3 and 3 ', and the cut leaf is conveyed to the rear of the leaf cutting device 6 from the middle portion of the chassis 2 to the rear. The onion digging blade 8 and the onion conveying device 9 are provided below or on the side of the leaf stalk conveying device 7 so as to face the starting end of the leaf stalk conveying device 7. The onion transport device 9 can be raised and retracted to a non-working position, and an elevator 11 connected to the storage device 10 is provided behind the onion transport device 9.
And a leaf stem processing device for an onion harvester, wherein the elevator 11 has a configuration in which a starting portion can be communicated with the leaf stem conveying device 7 with a terminal portion as a fulcrum.

[Action / Effect]

In harvesting the four onions grown on the furrow, first, the cutting of leaves and stems of two onions is performed.

In this case, the engraving blade 8 and the onion transporting device 9 are raised by operating the hydraulic cylinder 12, and are adjusted to move to the non-working position. On the other hand, the elevator 11 operates the hydraulic cylinder 13 to reduce the size, raise the starting end portion, and connect it to the terminal end portion of the foliage transfer device 7 so as to be able to carry over and transfer.

Then, the undercarriage 2 is advanced in the state shown in FIG. 1 to cut the leaves and stems of the two onions. At this time, since the adjacent two onions have raised the digging blade 8, the digging is performed. It will not be done.

When the undercarriage 2 is moved forward in this manner, the two onions are cut off by the foliage cutting device 6, conveyed upward and rearward by the foliage conveying device 7, reach the elevator 11, and are sent upward.

When the undercarriage 2 is continuously advanced in this way, only two of the four onion rows grown on one ridge will have their leaf stems cut sequentially.

When the work on one ridge on the outward path is completed as described above, the operation on the return path is started. At this time, the digging blade 8 and the onion transport device 9 are moved downward by operating the hydraulic cylinder 12 to dig the lower part. Move to position and start work.

Then, as the undercarriage 2 advances, the engraving blade 8 acts on the onion whose leaf stem has been cut on the outward path, and performs engraving.

Then, the excavated onion is conveyed rearward by the onion conveying device 9 and discharged from the end portion to the field scene.

On the other hand, the two adjacent onions are firstly raised by the raising lugs 4 of the leaf stem raising devices 3 and 3 'and cut by the leaf stem cutting device 6 as shown below, and upwardly rearward by the leaf stem transporting device 7. Conveyed.

As described above, the four onions on one ridge are subjected to cutting and trimming of the leaves and stems two by two.

As described above, the present invention has a feature that the leaf stem raising device and the leaf stem cutting device can be compactly configured.

Then, when configured as in the embodiment shown in FIG.
Cutting on the leaves and stems with the onion planting strips as one unit,
Since the digging operation can be performed, there is a feature that the operation efficiency can be improved by coping with the operation practice by the transplanter.

In addition, the function and effect of eliminating the conventional defect described at the beginning cannot be overlooked.
