Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a head and leaf harvester capable of cutting an upper part of a shoot root with a rotary blade when transporting and harvesting head and leaf vegetables such as cabbage from a field while harvesting. Related to the device.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Application Laid-Open No. 63-138525, the roots of roots of cabbage, such as cabbage, are pulled out from the ground by two screw conveyors that hold the roots of both sides of the leafy vegetables and conveyed rearward. In the headed leafy vegetable harvesting machine that can cut and harvest the upper part of the root by a rotary blade, the upper part of the root of the stem is cut by a rotary blade above the rear part of both screw carriers.

[0003]

However, this type of head and leaf vegetables cultivated in the field is not uniform in shape, and when these roots are cut by the above-mentioned apparatus, the cutting positions are variously changed. If the accuracy is uneven, the product value will be reduced if it is too short, and if it is too long, it will have to be cut again manually, which is troublesome, and the demon leaves on the bottom side of the head part are used for fresh food. The problem was that it was not possible to remove it neatly so that it could be immediately provided.

[0004]

SUMMARY OF THE INVENTION The present invention is designed to solve such a problem and to cut the upper side of the shoot root portion effectively and effectively. A clamping conveyor is provided to change the posture so that the roots of the heads are horizontal, and the handle is provided on the lateral side of the conveyor for the heads, which is disposed at the rear of the conveyor. And a rotary blade that can be pushed and moved.

[0005]

Therefore, the stem roots of the head and leaf vegetables are pulled out of the ground by the two screw carriers that sandwich the stem from both sides and transported rearward, and then the stem roots are turned sideways by the clamping conveyor that clamps and transports the stem roots. When the handle is pushed and the rotary blade is moved to the upper end of the root of the shoot, the upper end of the root of the shoot is cut neatly to obtain an optimal cut. In addition, the demon leaves on the lower surface of the head can be effectively removed.

[0006]

FIG. 2 is a side view schematically showing a head and leaf harvester, wherein a root portion a of cabbage is clamped from both sides at a front portion of the body supported by both crawlers 6 and conveyed while being pulled out from the ground. Two screw carriers 1a,
1b is slanted at the front low and rear high, and the screw conveying bodies 1a, 1
b, from the rear rear to the upper part of the fuselage, twisted two-sided conveying conveyors 3a and 3b for changing the posture so that the stem roots a sandwiched therebetween are oriented sideways, and both-sided conveying conveyors are provided. A rotary blade 2a is suspended below the start end side of 3a, 3b, and a space between the end portions of the above-mentioned clamping conveyors 3a, 3b and the accommodation box 7 at the rear of the machine is provided.
The upper and lower transport conveyors 4a and 4b that can contact both sides of the head portion A of the cabbage that has become horizontal, and the horizontal conveyor 4c that can contact the upper surface of the head portion A of the cabbage that has become horizontal. A leaf spring 8 is installed to extend and contact the lower surface of the head portion A and press the head portion A toward the transfer conveyor 4c on the lateral side opposite to the conveyor 4c. Is provided with a rotary blade 2 driven by a motor 10 which is elastically pressed outward by a compression spring 9 and can be pushed and moved inward by a handle 5.

Therefore, the roots a of the head and leaf vegetables are pulled out from the ground by the two screw transport bodies 1a and 1b which clamp the roots a from both sides, and are transported rearward. Then, the roots a are the starting ends of both the gripping conveyors 3a and 3b. As shown in FIG. 5, the rotary blade 2 cuts the root on the lower end side of the stem root part a as shown in FIG. 5, and thereafter, by the sandwiching conveyors 3a and 3b, as shown in FIGS. a is changed to a horizontal orientation, and the conveyors 4a, 4b,
4 and FIG.
As shown in FIG. 4, the head portion A is pressed toward the conveyor 4c by the leaf spring 8, and then the rotary blade 2 is stalked as shown by a virtual line in FIG. When moved to the upper end side of the root a, as shown in FIG.
It is possible to cut the upper end side of the shoot root part a neatly so as to be an optimal cut, and it is possible to effectively cut off the demon leaf Aa on the lower surface of the head part A, and the cut head part A is stored in a storage box as it is. 7 to be stored.

[0008]

As described above, according to the present invention, the root portions a of the head and leaf vegetables are pulled out from the ground by the two screw carriers 1a and 1b which hold the root portions a from both sides, and are conveyed rearward. The posture is changed so that the stem roots a become horizontal by the sandwiching conveyors 3a, 3b to be conveyed, and the rotary blade 2 is pushed by the handle 5 in a state of being conveyed by the conveyors 4a, 4b, 4c in that posture. By moving to the upper end side of a, it is possible to cut the upper end side of the stem root part a neatly so as to be an optimal cut, and to effectively cut off the demon leaves on the lower surface of the bulbous part A. Therefore, various headed leafy vegetables having different shapes can uniformly cut the stem root part a, and the cutting accuracy is improved so that the cuts are optimally aligned, so that a high commercial value crop can be obtained. It has a feature that can be suitably implemented.
