Description

[Technical Field]

[0001] In the cultivation of plants such as cucumbers, a cultivation method called "vine-down cultivation" is practiced in which the main branches are pinched off and then the several secondary vines that emerge are successively trained to the side without being pinched off, thereby achieving repeated harvesting. The present invention relates to a vine training device used in this vine-down cultivation method. [Background technology]

[0002] Patent Document 1 describes a known training device for guiding vine tips upward without damaging the vines in the down-dragging cultivation of plants such as cucumbers. This training device has a down-dragging vine holder and a main body fixing part formed integrally with it. The down-dragging vine holder has a V-shaped holding part that opens from the base on one end to the other end on the same plane. The main body fixing part is formed by bending downward from the base side of the down-dragging vine holder to a plane that includes the V-shaped holding part of the down-dragging vine holder.

[0003] [Patent Document 1] Utility Model Registration No. 3107339 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional plant attractor 201 is shown in Figure 12. This attractor 201 is constructed by bending a single wire and includes a main body fixing portion 202 and a descending vine holding portion 203. Generally, the plant attractor 201 is used by engaging the main body fixing portion 201 with a dovetail-shaped inner space 105 in the longitudinal direction of a long metal support frame 101, which is installed horizontally at a predetermined height along the ridge. Meanwhile, the plant vine is lowered from the rear side of the support frame 101, from which the descending vine holding portion 203 extends. The plant attractor 201 is attached to the support frame 101 in parallel with the plant vine lowering. Therefore, the attachment of the plant attractor 201 to the support frame 101 is an inefficient operation performed from a position where the inner space 105 of the support frame 101 is not visible. Furthermore, the support frame 101 is a long metal body, and it is very expensive to install it along the many ridges in a farm field. Therefore, an object of the present invention is to provide a guide device for vine-down cultivation that can be easily attached to a cable that can be installed inexpensively in a field. [Means for solving the problem]

[0005] In the following description, reference will be made to the reference numerals in the accompanying drawings, but the present invention is not limited thereto. To solve the above problems, the attracting device 1 of the present invention is formed entirely by bending a single elastic metal wire of a predetermined length. The attracting device 1 comprises a pair of hooks 2 formed at both ends of the metal wire, a pair of descending wires 3 that bend and extend downward from the pair of hooks 2, a pair of ascending wires 4 that bend from the lower ends of the descending wires 3 and extend upward at a forward incline, and a pair of holding wires 5 that bend from the upper ends of the ascending wires 4 and connect to each other in a roughly V-shape to form a narrow crane holding space S between them. The attracting device 1 is attached to the rope L by passing the rope L through the hooks 2 in a weaving manner, either front to back or up and down. [Effects of the Invention]

[0006] According to the present invention, it is possible to provide a guide device for vine-down cultivation that can be easily attached to a cable that can be installed inexpensively in a field. [Brief explanation of the drawings]

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description will discuss embodiments of the present invention with reference to the accompanying drawings. In the following examples, the same components are designated by the same reference numerals in the drawings and the description thereof will be omitted. [Example]

[0009] The crane attracting device 1 of the first embodiment is a attracting device that is attached to a cord L that is installed horizontally at a predetermined height along the ridges of a field, as shown in Figures 1 and 2, and is formed as a whole by bending a single elastic metal wire of a predetermined length symmetrically about the center.

[0010] The attracting device 1 comprises a pair of left and right hooking portions 2 formed at both ends of the metal wire and entangled with the rope body L to be engaged therewith; a pair of descending wire portions 3 that bend and extend downward from the hooking portions 2; a pair of ascending wire portions 4 that bend from the lower ends of the descending wire portions 3 and extend diagonally upward and forward; and a pair of holding wire portions 5 that bend from the upper ends of the ascending wire portions 4 and extend diagonally downward and rearward, converging and connecting in an approximately V-shape to form a narrow vine holding space S between them.

[0011] The hooking part 2 comprises a pair of arms 21 each extending outward to the left and right from the upper end of the descending line part 3 along the rope L, and a pair of engagement pieces 22 each bending and extending rearward from the tip of the arm 21. The hooking part 2 is hooked onto the rope L by alternately displacing the bases 22a of the pair of engagement pieces 22 and the bases 21a of the pair of arms 21 up and down with elasticity, and passing the rope L between the bases 22a of the pair of engagement pieces 22 and the bases 21a of the pair of arms 21 in a weaving manner in the up and down direction.

[0012] The vines P are guided by inserting them from the front into the vine holding space S. When cultivating a large number of cucumbers or tomatoes, the vines P are guided sideways one after another along the rope L as the plants grow. Each time a new guide tool 1 is attached to the rope L, the guide tool 1 can be easily attached to the rope with one hand by elastically bending it. It is also easy to adjust the left-right position after attachment. [Example]

[0013] The hook portion 2 of the sling 1 in the second embodiment shown in Figures 3 and 4 is the same as that in the first embodiment. It comprises a pair of descending wire portions 3 that bend and extend downward from the hook portion 2, and a pair of ascending wire portions 4 that bend from the lower ends of the descending wire portions 3 and extend obliquely upward and forward. A pair of holding wire portions 5 are directed obliquely downward and rearward via intervening wire portions 6 that bend and descend from the upper ends of the ascending wire portions 4. In this case, even if the sling 1 rotates and tilts relative to the rope body L due to the position of the center of gravity, the holding wire portions 5 can be positioned closer to horizontal than the overall tilt. This makes slinging easier and increases work efficiency. [Example]

[0014] 5, 6, and 7, a pair of holding wire portions 5' of a sling device 1 in a third embodiment are directed diagonally downward and rearward via intervening wire portions 6 that bend and descend from the upper ends of ascending wire portions 4, as in the second embodiment. However, because the intervening wire portions 6 of the pair of holding wire portions 5' are bent diagonally downward and rearward from the upper ends of ascending wire portions 4 on different sides, the holding space S formed between them has a bent V-shape with a narrow opening in a plan view, as shown in FIG. 7. In this case, the temple P will not easily fall out of the holding space S even if it is subjected to external forces such as wind. [Example]

[0015] 8 and 9, the hooking part 2 in the fourth embodiment includes a pair of arms 21 extending outward to the left and right from the upper ends of the descending wires 3 along the rope L, and a pair of engagement pieces 22' each bending and extending downward from the tip of the arm 21. The bases 22'a of the pair of engagement pieces 22' and the upper ends 3a of the pair of descending wires 3 are alternately displaced back and forth by elastic force, and the rope L is passed between the bases 22'a of the pair of engagement pieces 22' and the upper ends 3a of the pair of descending wires 3 in a weaving manner alternately in the front-to-back direction, whereby the hooking part 2 is hooked to the rope L. The other configuration is the same as that of the first embodiment. [Example]

[0016] 10 and 11, the hooking part 2 in the fifth embodiment includes a pair of curved portions 21' that are curved inward from the upper ends of the descending wire portions 3 along the rope L, and a pair of engaging pieces 22' that extend downward via the curved portions 21'. The hooking part 2 is hooked to the rope L by alternately displacing the middle portions 22'a of the pair of engaging pieces 22' and the upper ends 3a of the pair of descending wire portions 3 back and forth with elastic force, and by passing the rope L between the base portions 22'a of the pair of engaging pieces 22' and the upper ends 3a of the pair of descending wire portions 3 in a weaving manner in the front-to-back direction. The other configurations are the same as those of the first embodiment. As described above, any of the attracting devices 1 can be used by hanging them on the inexpensive rope body L, which can contribute to reducing equipment costs. [Explanation of symbols]
