Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root vegetable harvester for harvesting root vegetables such as onions, carrots, radish, garlic, etc., which are planted in ridges.

[0002]

2. Description of the Related Art In an onion harvester, which is an example of a root vegetable harvester as described above, for example, Japanese Patent Laid-Open No. 2001-289.
As disclosed in Japanese Patent Publication No. 20, the root stems of the root vegetables, which are located on both sides of the root vegetables to be harvested and which protrude from the planting holes of the multi-sheet hung on the ridge, are vertically moved by the locking claws. There is a device equipped with a plurality of leaf stem pulling devices that are pulled up by, and among the plurality of leaf stem pulling devices conventionally equipped in such root vegetable harvesters, each leaf stem pulling device that acts on the leaf stems between root vegetables. Was configured such that the tips of these locking claws had the same lobes for raising the foliage drawn at the lower end of the foliage raising device.

[0003]

By the way, in the case of covering the ridges with a multi-sheet, naturally, the place that covers the bottom of the ridge should be the one that covers the predetermined root vegetables among the plurality of root vegetables. It is designed to prevent curling up of the multi-sheet by placing soil, so that in the sheet part covering the root vegetables, the part where the curl prevention is applied is better than the part where the curl prevention is not applied. It is designed to sink.

Therefore, as in the above-mentioned prior art, a leaf-stalk pulling locus in which the tips of the locking claws of the respective leaf-stem pulling devices acting on the leaf stems between root vegetables are drawn at the lower end of the leaf-stalk pulling device. If the height is adjusted to the height of the seat where the curl is prevented, the locking claws will be placed on the seat where the curl is not prevented. There is a risk that the multi-sheet will be stabbed and pulled up together with the leaf stem, and conversely, if the height position is adjusted to the sheet height at a place where curl prevention is not performed, curl prevention is not performed. There is a possibility that the locking claw floats up from the position where the locking claw is lifted, and the leaf claw may not be properly pulled up by the locking claw.

An object of the present invention is to construct each leaf-stem pulling device so that their locking claws act favorably on the leaf-stalks of root vegetables, and to pull up the leaf-stems to cause damage to the multi-sheet. It is to ensure that it can be done reliably and satisfactorily.

[0006]

[Means for Solving the Problems] [Structure] In order to achieve the above object, in the invention according to claim 1 of the present invention, harvesting is performed by a root vegetable harvester for harvesting root vegetables planted in a ridge. Equipped with multiple leaf stem pulling devices that are located on both sides of the root vegetable and project the leaf stem of the root vegetable protruding from the planting hole of the multi-sheet hung on the ridge by vertically moving the locking claws. However, among the plurality of the leaf-stem pulling devices, the first leaf-stem pulling device that acts on the leaf stems of the portion where the multi-sheet is prevented from curling between the root vegetables, The locus of pulling up the leaf stem drawn by the lower end portion of the leaf pulling device by the tip of the locking claw is lower than that of the second leaf pulling device acting on the leaf stem where the sheet is not curled. Configured to.

[Operation] According to the invention of the above-mentioned claim 1, the first leaf stem pulling device that acts on the leaf stem of the portion where the multi-sheet is prevented from being rolled up between the root vegetables is the sheet at that portion. A second leaf stem pulling device that acts on the leaf stalks of the root vegetables that are not curled in consideration of the fact that the height of the sheet is lowered by the prevention and becomes lower than the sheet height of the portion that is not curled. Since the locus for pulling up the leaf stem is configured to be lower than that of the multi-sheet, the locking claw of the first leaf stem pulling device prevents the leaf stem from being rolled up in the location where the multisheet is prevented from rolling up. Thus, it is possible to operate in a suitable state in which the floating from the portion where the curl is applied is avoided, and thus it is possible to favorably pull up the leaf stem that has fallen into the portion where the curl prevention of the multi-sheet is applied.

In addition, the second leaf stem lifting device that acts on the leaf stems of the multi-sheet between the root vegetables, where the curl prevention of the multi-sheet is not performed, is the location where the sheet at the location is curled between the root vegetables. In consideration of the fact that the leaf height is higher than the sheet height of No. 1, since the state is such that the lobes for pulling up the stems are higher than the first stem for pulling up the stems, the location where the multi-sheet curl is not prevented. With respect to the leaf stem, the occurrence of the problem that the locking claw of the second leaf stem pulling device pierces the sheet portion where the curl is not prevented and pulls up the multi-sheet together with the leaf stem is avoided. It works in a suitable state, so that the leaf stem that has fallen into a portion of the multi-sheet that is not curled can be pulled up well.

[Effect] Therefore, regardless of whether or not the multi-sheet is curled up, the leaf stems between root vegetables can be pulled up by a corresponding leaf stem pulling device without causing damage to the multi-sheets. As a result, it has become possible to reliably and satisfactorily perform, and thus, it is possible to easily and surely lift the root vegetables from the ridges and cut the leaf stems using the leaf stems.

[Structure] In the invention according to claim 2 of the present invention, in the invention according to claim 1, a third one of the plurality of said leaf stem pulling devices which acts on the leaf stem of the ridge shoulder side portion.
The leaf stem pulling device is configured such that the lobes of the leaf stem are lower than that of the first leaf stem pulling device, and the fourth leaf stem pulling device acting on the leaf stem of the ridge is the third leaf stem pulling device. The locus for pulling up the leaf stem was configured to be lower than that of the device.

[Operation] According to the second aspect of the present invention, there is provided a third leaf stem pulling device which acts on the leaf stem of the ridge shoulder side portion,
Considering that the side of the ridge becomes lower than the sheet height of the portion where curling is prevented between root vegetables, and also becomes higher than the sheet height of the ridge bottom, multi-sheet rolling between root vegetables is considered. The locus of pulling the stem is lower than that of the first stem pulling device that acts on the stem of the spot where the prevention is applied, and the locus of pulling stem of the stem is lower than that of the fourth stem pulling device that acts on the stem of the ridge. Since it is configured so that
For the leaf stalks on the side of the ridges, the locking claws of the third leaf stalk pulling device are lifted from the side of the ridges and pierced into the seat on the side of the ridges to pull up the multi-sheet with the stems. Thus, it becomes possible to operate in a suitable state in which the occurrence of the problem of being caused is avoided, and thus it is possible to satisfactorily pull up the leaf stem that has fallen into the ridge shoulder side portion.

Further, the fourth leaf stem lifting device acting on the ridges of the ridges is provided on the ridges of the ridges in consideration of the fact that the ridges are lower than the seat height of the side of the ridges. Since the locus for pulling up the stem is lower than that of the third stem pulling device that operates, the locking claws of the fourth stem for pulling up the stem of the furrow are different from those for the stem of the furrow. It becomes possible to work in a suitable state in which the floating from the root is avoided, and thus it is possible to satisfactorily pull up the leaf stem that has fallen to the ridge.

[Effects] Therefore, it is possible to reliably and satisfactorily pull up the foliage that has fallen in various states along the shape of the ridge by the corresponding foliage pulling device without causing damage to the multi-sheet. As a result, it has become possible to easily and surely pull up root vegetables from the ridges and cut the stems using the stems.

The rolling up of the multi-sheet F is prevented, so that in the sheet portion covering the space between the onions, the portion covering the space between the onions at the center of the left and right where the rolling is prevented is left and right where the rolling is not prevented. It is designed to sink more than the area between the onions on both sides.

Therefore, in each of the stem pulling devices 10, the first stem pulling device 10A that acts on the stem Wb that has fallen into the portion covering the space between the onions at the center of the left and right where the multi-sheet F is curled is The tips of the locking claws 23 have a tip end of each locking stem 23 more than the second leaf stem pulling device 10B that acts on the leaf stem Wb that has fallen into the place covering the left and right onions on which the multi-sheet F is not rolled. It is configured such that the lobe of stem pulling up k drawn at the lower end of 10 becomes low.

As a result, with respect to the leaf stem Wb which has fallen into a portion covering the space between the onions at the center of the left and right, which is in a state of sinking more than the portion covering the space between the left and right onions in the multi-sheet F, the first leaf stem is pulled up. The locking claw 23 of the device 10A operates in a suitable state in which it is prevented from being lifted up from its sinking position, and is lifted up more than the position covering the space between the onions at the left and right center of the multi-sheet F. With respect to the leaf stem Wb that has fallen into a place that covers the space between the onions on both the left and right sides, the locking claw 2 of the second leaf stem lifting device 10B is used.

Is formed in a wide spatula shape and has an upwardly curved shape when viewed from the front in the posture in which the stems are pulled up. As a result, when the leading end 23a of the locking claw 23 comes into contact with the multi-sheet F, the waist bending phenomenon easily occurs at the leading end 23a so that only the contact end side portion of the leading end 23a is bent and deformed. As a result, the reaction force of the locking claws 23 acting on the multi-seat F is reduced, and the dispersed state is wide, and the left and right side edges of the locking claws 23 are caught by the multi-sheet F. Therefore, the stem Wb can be prevented without damaging the multi-sheet F due to the catch of the locking claw 23.
Can be picked up reliably and satisfactorily and pulled up.

The locking claw 23 of the third leaf stem pulling device 10C acting on the leaf stem Wb lying down on the side of the ridge and the fourth leaf stem pulling device 10D acting on the leaf stem Wb lying down to the ridge hem.

The auxiliary member 42 for turning up the sheet is pivotally supported about the fulcrum b so as to be able to swing back and forth, and is linked to the earth smashing body 41 through the linking rod 45 to swing the earth smashing body 41 back and forth. It is designed to be rocked back and forth in synchronism with the movement, and by moving forward while cutting near the ridges, it is possible to reduce the rush resistance of the subsequent soil crushing body 41 into the soil and The hem on the right side of the hung multi-seat F is pushed up slightly and turned up to move forward. In this way, by using the sheet turning-up assisting tool 42 so that the right hem of the multi-seat F is free to make it easy to turn up the sheet, the succeeding soil crushing body 41 can turn up the multi-sheet F. It will be done smoothly and smoothly. In addition, from the auxiliary tool 42 for turning up the sheet, the hem of the multi-sheet F scooped up by the auxiliary tool 42 is guided to the soil disintegrating body 41 so that the multi-sheet F is caught on the earth disintegrating body 41. The sheet guide portion 46 to be avoided is extended.

After the airframe has passed while cutting the leaves in this way, the short-cut unleaved leaves Wb are multi-sheets F.
The multi-sheet F can be easily flipped up without being hindered by the leaf stem Wb. Then, when the multi-sheet F is turned off, the onion body W is cut into short leaves on the ridge.
a is lined up in a floating state, and this may be collected.

The multi-specific onion harvester is configured as described above, and with respect to the four onions W cultivated on the flat ridges covered with the multi-sheet F, it advances one stroke to the right in the traveling direction. The cutting of the stem Wb in the two-row onion W and the lifting of the onion body Wa are performed, and one reciprocating movement is performed to cut the stem Wb and the lifting of the onion body Wa in all the four-row onions W. After that, the multi-sheet F is removed by winding or turning it up to expose the ridges, and the onions W left on the ridges in a leaf-cut state. Are collected manually or by a collecting machine.

By the way, at the lower end of the first leaf stem lifting device 10A, a grounding wheel 55 that rolls on the multi-sheet F and detects a variation in seat height with respect to the first leaf stem lifting device 10A is swayed. The swing arm 5 is provided so as to be vertically displaceable with respect to the first leaf stem lifting device 10A via the moving arm 56.
6, the upper end of the first leaf stem pulling device 10 extends upward.
The engaging claw 23 of each leaf stem pulling device 10 is inserted into the supporting guide tool 57 mounted on the upper part of A and the displacement of the mark 58 marked on the upper end part with respect to the supporting guide tool 57 causes the locking claw 23 of each leaf stem pulling device 10 to move. A marking rod 59 for facilitating visual confirmation from the maneuvering position whether the vehicle is positioned at an appropriate height position with respect to
Is extended, and based on the displacement of the mark 58 with respect to the support guide 57, the hand handle 8 is rotated to change the height position of the harvesting mechanism B with respect to the idle front wheel 3,
The locking claw 23 of each leaf stem pulling device 10 can be easily positioned at an appropriate height position with respect to the multi-sheet F.
