Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaf vegetable converging device which facilitates loading and unloading of harvested leaf vegetables in a harvesting operation of leaf vegetables such as spinach, komatsuna and bok choy grown in a field.

[0002]

2. Description of the Related Art Spinach is a typical example of leafy vegetables, and is often grown in a house in a wide-row, multiple-row dense-planting method. For harvesting, place an empty container in the required amount near the workshop and spinach. Repeating the manual work of pulling out, root cutting, leaf preparation, and storing in the container, when the container is full, move it to a place where it does not interfere with the harvesting work, return the empty container instead and repeat the manual work again, the full container
It is common to carry one or two with both hands and carry it out of the house. In addition, as a technique for mechanizing this harvesting work, extracting, sandwiching, and loading it on the container, the extracted leaf vegetables are loaded into the container from the discharge port, when it is full, stop the machine and lower the full container and transfer it to an empty container. There is known an example of performing the work again and a method of stacking the extracted vegetables on a convergent sheet fed by a conveyor below the discharge port, rolling the convergent sheet and stopping both ends to carry it out. For example, Japanese Patent Application Laid-Open No. 2000-270656 and Japanese Patent Application No. 2
No. 000-144656.

[0003]

In the above-mentioned manual work, when storing leaf vegetables at the bottom of the container, care must be taken to avoid impact, leaf breakage, and unevenness, and place a large amount of containers in a narrow work space inside the house. It is necessary to carry an empty container and a full container, especially since it is held in front of the house when it is carried out, and the visibility at the feet is poor and dangerous. In the work with a harvester, the former has a long drop distance when loading on the bottom of the container and damages due to impact and uneven leaf breakage occur, and there are problems similar to manual work when carrying out the container from the house. In the latter case, a long conveyor is placed on the side of the machine, which impairs left-right balance, circulation, forward visibility, etc., and in the converging work, it takes time and effort to separate leaf vegetable converging ends, wrap up the entire circumference of the sheet, and align the stockholders. Is.

[0020]

Since the present invention has the above-mentioned structure,
The following effects can be obtained. That is, as described in claim 1, in a converging device that facilitates loading and unloading of harvested leaf vegetables in a harvesting operation of leaf vegetables such as spinach and bok choy cultivated in the field, the leaf vegetables are long at the loading port. A sheet receiving member on two sides parallel to the direction, a belt-shaped converging sheet that contacts the upper portion and extends in a right angle direction, and a movable locking member that detachably engages with both ends of the converging sheet and expands the converging sheet, Depending on the amount of leaf vegetables stacked on the convergence sheet at the loading port, the moving locking body is pulled by the convergence sheet to maintain the height position where the leaf vegetables are placed near the height of the loading port. The work operation for loading is small, and impact, leaf breakage, and unevenness due to a large drop height are prevented. Further, when the sheets are fully loaded, the bundling sheets form a substantially bunched state, so that bundling operation is also easy. Further, as described in claim 2, by making it possible to adjust the distance between the sheet receivers of the two sides which are in contact with the converging sheet and are parallel to each other, the stacking port can be placed horizontally on the converging sheet depending on the type and shape of the leafy vegetables. Rolling is prevented, and further, the effect that the convergent sheet when fully loaded is in a more convergent state is obtained.

Further, as described in claim 3, a container body in which only an upper surface serving as a loading port is open and a bottom surface is warped is arranged in parallel with two sides of the loading port parallel to the longitudinal direction of leaf vegetables. The movable locking body for fixing the two locking bodies is pivotally supported by the locking rotation shaft, and further, the movable locking body is pulled in the direction away from the two sides. By arranging the band-shaped converging sheet with a retaining ring in a detachable engagement arrangement, it is not necessary to place an empty container in the field, the work of carrying it is unnecessary, the work space is wide, and the carry-out work can be done safely. By maintaining the height position where the leafy vegetables are placed near the height of the loading port, the loading operation is small, and the impact, leaf breakage, unevenness, etc. due to the large drop height are prevented. Bundling operation because it forms a nearly converged state Easy to become effect can be obtained.

Further, as described in claim 4, a harvesting machine for extracting leaf vegetables cultivated in a field such as spinach and bok choy and carrying them while moving and discharging them to a specific side surface of the traveling machine body. In the specific position, a pair of parallel sheet receiving members serving as a loading port, a belt-shaped converging sheet that is in contact with the upper portion and extends in the perpendicular direction, and detachably engages both ends of the converging sheet to form a converging sheet. The movable locking body to be expanded is arranged, and the moving locking body is pulled by the convergence sheet according to the amount of leaf vegetables stacked on the convergence sheet between the sheet receivers, and the height position on which the leaf vegetables are placed is set to the loading port. By having a converging device configured to maintain near the height, it prevents impact, leaf breakage, unevenness, etc. due to a large drop height, and even if the bottom of the converging sheet falls near the full load, it has a smooth shape Prevents damage to green leafy vegetables Operation is facilitated bundled because converging sheet forms a substantially convergent state when full, further,
The effect that replacement work with an empty container is unnecessary is obtained.

Further, as described in claim 5, the converging device is rotatably supported on a line passing through the vicinity of the drop of the leaf vegetables to be released and in the traveling direction of the traveling body.
Since the converging device is attached at an angle that matches the type and shape of leafy vegetables, the stockers abut on the aligning body, improving the alignment of the stockers, and further, the effect of further preventing damage to the neighboring ridged vegetables is obtained. To be
