DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rhizome crop harvesting machine which is used for harvesting rhizome crops such as garlic, lily, tulip, and the like, in which the foliage is difficult to lodge.

[0002]

2. Description of the Related Art A conventional device is provided with a device for pulling a rhizome crop obliquely upward and backward by a pulling device comprising a pair of endless belts, cutting the foliage of the rhizome crop and discharging the crop into a field. It is known that root crops are collected and harvested by releasing the root crops rearward or laterally.

[0003] However, this type of harvester discharges root vegetables harvested on the ridge surface in tandem along the ridge, and cut leaves are discharged to the slopes or grooves of the ridge. The release position of stems to be cut separately (hereinafter referred to as remnants) is not regulated, and they are mixed in the release line of harvested root vegetables, which makes it difficult to pick them up when collecting them in later work. There is a problem that there is no.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the prior art.
A release device that regulates the release position of the remaining stem is attached, and the remaining stem after cutting the leaves is guided and released so as to be discharged to the slope or groove of the ridge similarly to the leaves, and the root vegetables to be harvested are harvested. The position is to be surely separated so that the remnant stem and root vegetables are not mixed, so that the harvesting operation is smooth.

[0005]

In a rhizome crop harvesting machine provided with a pulling device or a foliage cutting device comprising an endless belt, a lower transport device is provided below the pulling device, and a lower end of the lower transport device is rotated. A stem release device consisting of a body and a stem release derivative corresponding to the rotational trajectory of the stem release device are disposed,
The release position of the remnant stem separated by the foliage cutting device is regulated, and the remnant stem is induced and released so that it is separated from the release position of the root crop and is not mixed.

[0006] In a rhizome crop harvesting machine provided with a pulling device, a foliage cutting device, and a lower conveying device comprising an endless band, a remnant stem releasing device comprising a rotating body concentric with a rotation axis of a foliage cutting device having a rotary blade is provided. By mounting, the rotation direction of the rotary blade and the remaining stem release direction are matched to facilitate guidance to a predetermined release position.

[0007] In a rhizome crop harvester provided with a pulling device, a foliage cutting device and a lower conveying device comprising an endless belt, a stem releasing device comprising a rotating body and a stem releasing derivative corresponding to the stem releasing device are provided. It is arranged between the upper and lower rotating blades of the foliage cutting device and cut and separated into leaves, remnants and roots, making it easier to release even hard stems like garlic, especially leaves and roots. The remnant stem is repelled by a remnant release device so that it does not stay between the upper and lower rotary blades. We devised to avoid mixing.

[0008] In a rhizome crop harvesting machine equipped with a pulling device, a foliage cutting device, and a lower conveying device comprising an endless belt, the rotation direction of the remnant stem releasing device comprising a rotating body is the same as the rotation direction of the rotary blade of the cutting device. In such a way that the remaining stem is transported in the rotating direction on the lower rotary blade and the synergistic effect of the repelling action of the remaining stem releasing device, it concentrates on the left side of the fuselage and induces the release. It was configured to be able to do.

[0009] In a rhizome crop harvesting machine equipped with a pulling device, a foliage cutting device and a lower conveying device comprising an endless belt, a rotating body of a remnant stem releasing device which rotates in synchronization with a rotating blade of a foliage cutting device having a rotating blade is used. A structure in which a plurality of protruding portions are arranged on the circumference or a structure in which a plurality of blades are mounted on a concentric shaft, so that the stem is released in cooperation with the stem releasing derivative, The position where the remaining culm was released and the position where the root crop was released were surely separated so that the harvest could be easily collected.

[0010] In a rhizome crop harvesting machine equipped with a pulling device, a foliage cutting device and a lower conveying device comprising an endless belt, a guide cover for receiving and guiding a root plant portion cut and dropped is mounted, and its cross-sectional shape is adjusted in the front-rear direction. In order to prevent the falling point of the root vegetable portion from converging to prevent scattering, the mixture with the leaf portion and the remaining stem was avoided.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, when harvesting rhizome crops such as garlic and lily which have strong stems, the excavated root vegetables are released to the ridge surface, and the foliage is likely to be indented in the subsequent work. The leaves are cut off and the stems are treated as remnants, but the leaves and remnants are discharged to the slope or ditch of the ridge, and the release position is separated from the root vegetables released on the ridge. Then, the configuration of the device is devised so as to facilitate the collecting operation of the root vegetable portion, and the device is implemented in the garlic harvester.
