Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester for harvesting non-heading leafy vegetables such as spinach.

[0002]

2. Description of the Related Art There is known a self-propelled vegetable harvesting machine that picks up vegetables to be planted in a field, conveys them to a harvesting section at an upper part of a vehicle body, and harvests them. Most of them were used for harvesting root vegetables such as carrots or headed vegetables such as cabbage, and were not suitable for harvesting non-head leafy vegetables such as spinach. In other words, non-heading leafy vegetables such as spinach grow in a growing state in which the leaf part that is the target part of the harvest approaches or contacts the field scene and spreads out to the surroundings. In addition to causing a lot of loss in picking up the leaf part that is a part, it is easy to damage the leaf part, and it is unavoidable that soil adheres to the leaf part, and The problem arises that it takes a lot of time and effort to remove the soil that has adhered or mixed.

[0003]

Therefore, according to the present invention, non-heading leafy vegetables such as spinach are taken in to reduce loss and damage to the leaves, and to prevent soil from adhering to or mixing with the leaves. The purpose of the present invention is to provide a harvesting machine that enables good harvesting in.

[0004]

In order to achieve the above object, a non-head leafy vegetable harvester according to the present invention is a self-propelled vehicle (1).

Soil or lower leaves that have adhered or mixed while being transported
A soil removing device (12) for sucking and removing dead leaves is provided. Then, the collecting section (B) disposed below the conveyance end portion of the sandwiching conveyance device (9) is connected to the non-heading leafy vegetables (1
5) a carrying device (23) for placing and carrying, and a carrying device (2
3) is composed of a container (25) for receiving non-headed leafy vegetables sent from the container (25), and the container (25) is carried out by the carry-out device (2).
It is possible to change the position in the lateral direction with respect to 3), and it is preferable to provide a binding machine (24) for temporarily binding the non-ballooned leafy vegetables (15) during the transportation of the carry-out device (23).

[0005]

When the non-heading leafy vegetable harvester according to the present invention advances,
A defoliating device (8) located at the front end of the non-heading leafy vegetables (15) in a state of approaching or in contact with a field scene lifts up the leaves so that the whole leaves are gathered. Meanwhile, the non-heading leafy vegetables (15) are guided to the starting end portion of the sandwiching and conveying device (9) and are inherited by the sandwiching and conveying device (9), and the cutter (10 which advances in the soil near the inheritance is carried out. ) Cut or dug up the root.

Then, the non-heading leafy vegetables (15) are lifted and transported by the sandwiching and transporting device (9) and gradually changed to a sideways posture during the transportation. The soil removing device (12) installed corresponding to the sandwiching and conveying path (20) of the sandwiching and conveying device (9) works on 15), and the non-heading leafy vegetables (15)
Removes soil, lower leaves, dead leaves, etc. that adhere to or are mixed with.

Then, the cleaned non-headed leafy vegetables (1
5) is sent from the transport end portion of the sandwiching transport path (20) onto the transport device (23) of the collecting unit (B), and the transport device (2
If a binding machine (24) is provided during the transportation of 3), the container (25) is temporarily bound by the binding machine (24).
The non-heading leafy vegetables (15) are collected in the container (25), and the container (2
By changing the position of 5) laterally, the container (2
The non-heading leafy vegetables (15) can be collected uniformly in 5) without waste.

Note that the binding machine (24) for temporarily binding the non-heading leafy vegetables may be omitted, and the non-heading leafy vegetables may be stored in the container without being bound.

[0019]

Since the present invention is configured as described above, it has the following effects. In the non-heading leafy vegetable collector according to claim 1, the leaf straightening device (8) sets a leaf portion of the non-heading leafy vegetable (15) which is planted in a state of approaching or contacting a field scene and spreading to the surroundings. The leaves are satisfactorily picked up by lifting them in a scooping manner and guiding them toward the start end of the sandwiching and conveying device (9) while gathering the entire leaves, and the soil removing device (12) is used during the conveyance. Adhered or contaminated soil, lower leaves and removal are cleaned, so that efficient harvesting with less harvesting loss and post-adjustment is performed.

Further, in the non-heading leafy vegetable collecting machine according to claim 2, the collecting section (B) is provided with a conveying device (23) and a container (2).
5) and comprises a container (25) and a transport device (23)
Since it is possible to change the position laterally with respect to
A container (25) in addition to the effect of the first aspect.
The non-heading and leafy vegetables collecting machine according to claim 3 has an advantage that the non-heading and leafy vegetables can be collected uniformly in the container by the horizontal movement of the binding machine. Since the non-heading leafy vegetables (15) are temporarily bound together, there is an advantage that the non-heading leafy vegetables can be more easily handled during the adjustment work performed after the collection.
