JP 2006-149258 A

  The present invention facilitates the harvesting operation with one hand even in a narrow place where there is contact with a branch tree, can be reliably taken in without causing trauma to the harvested crops, and It is an object of the present invention to provide a harvesting aid that can be easily taken out.

  As means for solving the above-mentioned problems, a harvesting assisting device according to the present invention includes an annular support made of a flexible material having an annular shape and a palm of a harvesting worker fixed to the outside of the annular support. It comprises a mounting portion that is mounted in contact with both the back of the hand, and a container that is formed of a bag-shaped container and has an opening edge of the container attached to the annular support.

  According to this configuration, it is possible to harvest the crop using the thumb and other fingers by attaching the harvesting assisting device to one hand. In addition, even if a branch tree hits the annular support, force can be applied to maintain the annular shape due to flexibility, and the container entrance is not blocked, so it was harvested by grabbing with the thumb and other fingers. Agricultural crops can be easily captured by releasing the grasped finger at the grasped position. Moreover, since the annular support body is shape-maintained, the harvesting auxiliary instrument of the present invention can be easily taken out without blocking the outlet of the captured crop even if it is inverted.

  It is preferable that the container of the accommodating part is made of a net. According to this configuration, it is possible to remove unnecessary items such as loose pieces detached from the harvested crops by dropping them from the gaps of the net without performing another work other than harvesting the crops and taking them into the container. .

  It is preferable that the mounting portion is formed of an annular band whose length of the entire circumference can be adjusted. According to this configuration, the length of the entire circumference of the annular band can be adjusted freely, so that it can be adjusted to various hand sizes.

  It is preferable that the mounting portion further includes an auxiliary member that is fixed to the annular support and that hooks at least one of the fingers excluding the thumb to assistly fix the hand. According to this configuration, in addition to bringing the annular band into contact with both the palm and the back of the hand, the harvesting auxiliary device of the present invention can be more reliably integrated by hooking at least one finger and fixing it additionally. Can be installed.

  It is preferable that the annular support is held in an elliptical shape. According to this configuration, the annular support has both a portion having a weak repulsive force due to the flexibility due to the elliptical geometric shape and a portion having a strong repulsive force due to the flexibility. When a force is applied to the portion where the repulsive force is weak, the annular support can be more easily deformed. Thereafter, the original shape can be restored in a very short time.

  It is preferable that the annular support is formed of a band having a thickness different from that of other portions on a part of the entire circumference. According to this configuration, by providing the part of the entire circumference of the annular support with a part having a thickness different from that of the other part, the annular support that is formed against the flexibility is relatively It is possible to generate a portion where the repulsive force due to flexibility is weak at a very thin portion and a portion where the repulsive force due to flexibility is strong at a relatively thick portion. Thereby, after deform | transforming an annular support body easily, it can be restored to the original shape in a very short time.

  The annular support is preferably made of a wire. According to this configuration, a simpler structure can be achieved.

  According to the present invention, it is possible to carry out a harvesting operation with one hand even in a narrow place where there is a contact with a branch tree, and it is possible to ensure that the harvested crop is not damaged and the inside of the container is surely. And can be easily removed from the container simply by inverting it. Further, since the friction assisting force due to the contact with the branch tree is reduced by the deformation of the harvesting assisting device, the harvester can easily harvest by putting his hand into the narrow branch tree.

  Next, a method for harvesting blueberries using the harvesting assisting instrument 10 according to the present invention will be described. As shown in FIG. 12, it inserts in the annular band 18 of the mounting part 12 of the harvest assistance tool 10 so that both a palm and the back of a hand may contact. At this time, if the length of the entire circumference of the annular band 18 is not a desired length, one end of the annular band 18 is peeled to release the coupling, and the length of the overlapping surface 24 between the one end and the other end is released. By changing L, the length of the entire circumference is adjusted to a desired length. Further, when it is desired to change the position in the height direction of the annular band 18 with respect to the annular support 11, the bolt 20 and the nut 21 are loosened in a direction perpendicular to the longitudinal direction of the band plates 11a and 11b of the annular support 11. The stay 17 is moved and adjusted, and the bolt 20 and the nut 21 are fastened and fixed again. Then, with the fingers other than the thumb, one finger (for example, a little finger) that facilitates the user's work is inserted into the ring 31. When it is necessary to adjust the length of the entire circumference of the ring 31, the same procedure as that for the annular band 18 of the mounting portion 12 is performed. Holding the finger in the ring 31 so that it can be grasped a little, the finger can be hooked on the ring 31 and fixed, and a harvesting posture can be taken.

  Next, as shown in FIG. The harvestable blueberry 94 at the branch tip 93 is selected, and with the harvesting assisting device 10 attached, the blueberry 94 is harvested by pinching and twisting with a free thumb, index finger, middle finger or the like. When the blueberry 94 pinched with the thumb and forefinger or middle finger is released at the position where the blueberry 94 is peeled off, the blueberry 94 falls in the direction of gravity at that position. Since the annular support 11 is open, if it is dropped at that position, it can be reliably taken into the container of the accommodating portion 13. When harvesting blueberries in the back branch by putting a hand between the narrow branches, the ring-shaped support 11 is easily deformed and returned to the original position even if it hits the branch tree, so that harvesting is easy. You can work with both hands.

  When the blueberry in the container 13 is full, the wrist is turned over above the tray 66 installed in the transport vehicle 50, and the blueberry is taken out with the opening of the annular support 11 facing downward. Even in this case, the shape of the opening of the annular support 11 is maintained, and the shape of the container of the storage portion 13 is also maintained, so that the outlet of the harvesting assisting device 10 is not blocked and the blueberries can be easily taken out. Can do.

  When the tray 66 becomes full, the stopper member 70 of the transport vehicle 50 is pulled upward, and the tray 66 and the empty tray 66 are exchanged. Thereafter, the stopper member 70 is inserted again from above.

  If it does in this way, a blueberry can be harvested with one hand, and it can take in to the harvesting auxiliary instrument 10, and the working efficiency of harvesting can be improved significantly.

  Next, the use of the storage work auxiliary instrument 95 that does not require the work of replacing the tray 66 in the storage method described above will be described. Similarly to the above-described accommodation method, blueberries are transferred directly from the harvesting assisting device 10 to the tray 66 in the uppermost tray 66 of the transport vehicle 50. For the trays 66 other than the uppermost tray 66 of the transport vehicle 50, the delivery destination of the line selector 103 is designated in advance, and then the blueberry is transferred from the harvesting auxiliary device 10 to the hopper 100 of the storage auxiliary device 95. . When the destination tray 66 is full, the line selector 103 is switched to the tray 66 where another storage location remains, and blueberries are put into the hopper 100 as described above.

  In this way, if the storage work assisting device 95 is used, it is not necessary to replace the heavy tray 66 that is full of blueberries, so that time loss and physical burden can be reduced.

  The present invention is not limited to the embodiment, and various modifications are possible. For example, the annular support 11 may be made of a wire instead of the strips 11a and 11b. In addition, the area of the opening surface may be changed by sliding the portion where the strips 11a and 11b of the annular support 11 overlap. Further, the mounting portion 12 may be one in which components including the stay 17 and the ring mounting stay 29 are integrated.

  If there is a risk of deformation due to the weight of the blueberry accommodated in the annular support 11, as shown by a two-dot chain line in FIG. 1, the tension member 106 may be attached between the stay 17 and the opposite portion of the annular support 11. Good.
