Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaf tobacco harvesting machine for picking and harvesting leaves from the trunk of a leaf tobacco.

[0002]

2. Description of the Related Art Conventionally, a plurality of leaves of tobacco leaves have grown on one trunk. For example, the lower leaves growing on the lower part of the trunk and the middle part of the trunk grow. Since the quality of the leaf is different between the true leaf that is present and the top leaf that grows on the upper part of the trunk, the leaf mogating work is performed separately.

[0003] In the leaf gluing work, the tobacco leaves grow upward on the circumference of the trunk at spiral intervals with various intervals. There are problems such as leftovers and damage to leaves, which lowers the product value, and it is the current situation that they are done manually.

[0004]

However, although it is possible to prevent the leftover leaves and damage to the leaves described above by manually stripping tobacco leaves, it takes too much time due to heavy labor and the cost performance is poor. There was a problem.
In particular, when the dense lower leaves were to be harvested, the user had to bend over and suffered from a bad working posture.

Therefore, there has been a demand for the development of a leaf tobacco harvester capable of preventing leaves left behind, damages and the like and automatically carrying out leaf picking.

[0006]

Therefore, in the present invention, a traveling device capable of self-propelled across the ridges of a tobacco leaf is provided with a leaf mopping device for stripping leaves from the trunk of the tobacco leaf. A pair of left and right leaf mogul portions and a vibrating portion that vibrates both leaf mogul portions in the up-and-down direction are provided, and a pair of left and right leaf mogul portions are provided with rotating body mounting frames that extend in the front-rear direction. On the mounting frame, a plurality of leaf mog rotors are rotatably mounted around the vertical axis at intervals in the front-rear direction, and a pair of left and right leaf mog rotors are arranged to face each other. It is intended to provide a leaf tobacco harvesting machine, characterized in that a plurality of leaf moat protrusions extending radially are provided on the mochi rotary body.

Further, according to the present invention, the leaf mower is detachably attached to the traveling device and is swingable to the left and right, and the pair of left and right lobe portions are adjusted to the ground height and the height of the front end side and the rear end side is adjusted. An adjustment part is provided for adjusting the difference and the relative distance between the left and right sides, and a mochi leaf receiver is attached to each of the lower left and right sides of the traveling device. It is also formed to have a width approximately the same as the front and rear width, the base end edge part is pivotally supported in a vertically swingable manner, and the tip end edge part is extended substantially along the top from the hem of the ridge. Have.

[0008]

[Operation] When harvesting leaves from the trunk of the tobacco, the trunk is placed with the traveling device straddling the ridge of the tobacco and between the pair of left and right leaf mowers of the leaf mower attached to the traveling device. Drive while passing through.

At this time, the pair of left and right leaf mog portions vibrates in the vertical direction by the vibrating portion, and the leaf tobacco is relatively moved between the leaf moat rotating bodies which are arranged to face the left and right sides of the leaf moat portions. That is, the plurality of radially extending leaf moat protrusions provided on the two leaf moth rotating bodies abut on the trunk and slide up and down. Removes leaves by pushing down the roots of the leaves.

[0010] In this case, the leaf mogating protrusions, which are arranged to face each other on the left and right sides, move vertically while rotating from the left and right sides facing each other and rotating in conjunction with the relative movement of the trunk. Depressing force is reliably applied to the root part of the leaf that is spirally growing on the surface, and leaves are removed without damaging the leaves.

In addition, since a plurality of pairs of leaf mog rotors facing each other in the left-right direction are arranged in the front-rear direction as described above, both lobes are vertically moved while the trunk is moving between the lobes. Leaves within the range can be surely defoliated.

When the leaf picking device is attached to the traveling device so as to be detachable and swingable left and right, the leaf picking device can be detached from the traveling device for maintenance and the ridges of the tobacco leaf are bent. In this case, with respect to the traveling device that travels along the ridge, the leaf mower can swing the left and right and reliably guide the trunk of each leaf tobacco between the pair of left and right leaf mowers. Defoliation and harvesting can be performed without damaging the leaves.

When a pair of right and left leaf moats are adjusted above ground level, height difference between the front end side and the rear end side, and left and right relative distance adjustment can be adjusted by the adjusting parts, respectively, one trunk is attached to the trunk. Living leaves can be reliably defoliated and harvested for each part such as so-called lower leaves, true leaves, and top leaves.

Motif leaf receivers are attached to the lower left and right sides of the traveling device, respectively, and the front and rear widths of both of the moth leaf receivers are formed to be substantially the same as the front and rear width of the leaf moat portion, and the base end edge portion is formed. If it is pivotally supported up and down, and the tip edge extends from the hem of the ridge approximately along the top of the ridge, the leaf that is picked up by the leaf clip and falls will be secured by the leaf receiver. In addition, even if the ridge is bent, each mochi leaf receiver swings up and down to change its posture, preventing each mochi leaf receiver from colliding with the ridge. Therefore, smooth and reliable defoliation and harvesting work can be performed.
