Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a vegetable harvester for mainly harvesting vegetables having foliage such as ginger and onions.

"Prior Art" Conventionally, as shown in Japanese Patent Laid-Open No. 60-137207, there has been a technology of extracting vegetables from cultivated ridges and loading them on a traveling vehicle body.

"Problems to be solved by the invention" In the above-mentioned conventional technology, since the harvested vegetables are automatically placed on a traveling vehicle equipped with a conveyor for pulling out vegetables, labor saving of vegetable harvesting can be easily performed, but a predetermined amount. Since the vegetables of the above are randomly loaded on the traveling vehicle, extra mud is likely to adhere to onions, etc., and it is easy to crack into small lumps with ginger, etc. There was a problem.

Further, as shown in JP-A-60-224409, there was also a technique of releasing the extracted vegetables on the upper surface of the cultivation ridge and collecting the vegetables in a post-work, but since the released vegetables fall on the upper surface of the cultivation ridge. However, there is a problem that the worker needs to bend his waist low to pick up the vegetables, and it is not possible to easily reduce the labor of the vegetable collection work.

[Means for Solving the Problems] Therefore, in the present invention, the traveling machine body is provided with a pulling conveyor that holds the above-ground portion of vegetables and pulls it upward, and drives the conveyor by synchronizing the conveying speed of the conveyor with the traveling speed. In the vegetable harvesting machine, the underground portion of the vegetables is lifted on the upper surface of the cultivation ridge, and the above-ground height of the feeding end portion of the conveyor is formed to be higher than the feeding start end portion, and the vegetable is lifted by the conveyor. It is characterized in that a height difference is maintained between the start end and the rear end of the conveyor so that the vegetables maintain a standing posture after being discharged from the feeding end side to the cultivation ridge.

[Action] Therefore, since the vegetables released from the conveyor feeding end to the upper surface of the cultivation ridge maintain an upright posture, it is necessary for an operator to load the vegetables into a carrier or the like. There is no need for the worker to bend his or her waist when picking up, which can significantly reduce the labor compared to the conventional artificial vegetable harvesting work, and the worker collects the vegetables on the upper surface of the cultivation ridge by a carrier. You can easily simplify the work,
Compared to the conventional work of automatically loading vegetables on a traveling vehicle, the product value of vegetables can be prevented from decreasing, and the efficiency of collecting vegetables by workers can be improved and the quality of vegetables can be easily maintained. Is.

This embodiment is configured as described above, and when the rear wheel (21) is driven to travel across the ridge (31) and the front and rear wheels (4) and (21) are fitted in the drain groove (32). The front and rear wheels (4) and (21) are moved up and down by controlling the hydraulic cylinders (5) and (23) to support the pull-out conveyors (27) and (28) in a front-rear-rear-high posture.
Pull up the foliage of the ginger (26) standing on the ridges (31) with the grass collection belts (33) (34) and pull out the conveyor (27)
Hold by (28). And the conveyor (27) (2
8) Ginger (26) protruding upward is cut into pieces by the cutter (35) and discharged from the chute (42) to the outside of the machine, while the ginger (27) (28) holds and conveys the leaves. (26) is pulled up and the ginger (26) is raised on the upper surface of the ridge (31) to stand upright. The worker holds the remaining foliage and removes the ginger (26) for cleaning and packing. It is for harvesting work such as shipping,
The worker may be able to pick up (26), although it may be a position with a high back.

Although ginger (26) was harvested in the above-mentioned example, it goes without saying that other vegetables such as onions or radishes can be similarly harvested.

[Effect of the Invention] As is clear from the above embodiments, the present invention is a pulling conveyor (27) (2) that holds the above-ground portion of the vegetables (26) and pulls them upward.

In the vegetable harvester that drives 8), the underground portion of the vegetables (26) is lifted on the upper surface of the cultivation ridge (31) and stands above the conveyor terminal (27) (28) at the height at which it stands upright. The height is made higher than that of the feeding start end, and the conveyor (27) (2
The height difference that maintains the standing posture after the vegetables (26) lifted by 8) is discharged from the feed end side to the cultivation ridges (31) is formed between the start end and the rear end of the conveyors (27) (28). Since the vegetables (26) discharged from the feeding ends of the conveyors (27) and (28) to the upper surface of the cultivation ridge (31) maintain the standing posture, the vegetables (26) are loaded on a transport vehicle or the like. The work needs to be done by the worker, but when picking up the vegetables (26) on the upper surface of the cultivation ridge (31), there is no need for the worker to bend his or her waist low, which is more labor than the conventional artificial vegetable harvesting work. Can be significantly reduced, and the worker can easily simplify the work of collecting the vegetables (26) on the upper surface of the cultivation ridge (31) by a transport vehicle, and the vegetables (26) can be automatically transferred to the traveling vehicle. Compared with the conventional work of loading, it is possible to easily prevent the product value of vegetables (26) from decreasing, Vegetables by workers (26)
It is possible to easily improve the collection work efficiency and maintain the quality of the vegetables (26).
