Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hanging device for fruit cultivation used when cultivating fruits such as melon.

[Prior Art] Conventionally, for hanging cultivation of fruits such as melons, methods such as surface cultivation and three-dimensional cultivation have been known. Ground cultivating is a two-dimensional cultivation method, and a hanging tool proposed in Japanese Utility Model Publication No. 61-10642 is mainly used. Three-dimensional cultivation is a method of cultivating melons by hanging them directly on columns with strings, or by hanging melons with strings on the lines between the columns.

[Problems to be solved by the invention] However, there is a problem that the cultivation efficiency of ground creeping is lower than that of three-dimensional cultivation. On the other hand, three-dimensional cultivation involves the troublesome work of tying the strings one by one to the fruit pattern, stanchions or tension lines when suspending the fruits, and it is difficult to fix the position of the strings, so the fruits are shaded. However, there was a problem in that the growth of the fruit was hindered and the fruit was rubbed against the pillar and damaged.

The present invention has been made in view of the above problems, and while it is possible to grow fruits such as melon by a method belonging to three-dimensional cultivation, which has a higher cultivation efficiency than land-based cultivation,
An object of the present invention is to provide a hanging tool for fruit cultivation, which can easily and quickly suspend the fruit on the support and which can fix the hanging position of the fruit.

[Means for Solving the Problems] The hanging device for fruit cultivation of the present invention has a spiral part wound around at least half the circumference of the support, and one end of the spiral part toward the side of the support around which the spiral part is wound. The extending arm portion and the fruit hanging portion provided on the arm portion are integrally formed of a wire rod.

In this configuration, the one end of the spiral part from which the arm part extends may be the upper end or the lower end of the spiral part.
Further, in the spiral portion, one end portion of the arm portion that is extended and the other end portion that is the opposite side portion thereof are pressed against the column by the weight of the fruit when the fruit is suspended in the fruit suspension portion of the arm portion. For this to happen, the helix must have a length that wraps around at least half the circumference of the column.

[Operation] The operation of the hanging device for fruit cultivation having this structure, in which the arm portion extends to the upper end of the spiral portion, will be described.

When the spiral part is wrapped around the support, the fruit is hung on the arm or the weight of the arm causes the arm to try to rotate downward around the contact point between the upper end of the spiral and the support. While the upper end of the spiral part is pressed against the column by the other side, the predetermined part other than the upper end of the spiral part (the lower end if the number of turns of the spiral is 1/2) is from the side opposite to the upper end. It is pressed against the pillar. Therefore, two places including the upper end of the spiral portion are pressed against the column from opposite directions, the friction resistance between the spiral portion and the column increases, and the entire suspender is held by the column.

Against such an action, if the arm portion is lifted up a little, the frictional resistance is reduced. Therefore, the hanging device can be freely moved around the column, and when the hanging device is moved in such a manner, the direction of the arm portion, that is, the hanging position of the fruit is changed.

When the number of windings of the spiral portion is less than one, the arm portion is erected and the spiral portion is tilted with respect to the supporting column so that the spiral portion of the spiral portion is utilized to fit the spiral portion to the supporting column. It can be retracted or removed from the column.

[Example] FIG. 1 is a side view of a hanging device A for fruit cultivation of the present invention, and FIG. 2 is a plan view of the same. The hanging tool A is made by bending a single wire and integrally includes a spiral portion 1, an arm portion 2, and a fruit hanging portion 3. The spiral portion 1 in the illustrated example is wound once. The arm portion 2 extends linearly laterally from the upper end of the spiral portion 1 with a slight upward slope. The fruit hanging part 3 is formed by bending the tip of the arm part 2 into a U shape.

FIG. 3 shows a usage state of the hanging tool A. In this use state, the spiral part 1 is wound around the support column 5, and the arm part 2
The fruit F is hung by fitting and engaging the T-shaped portion of the fruit handle F ₁ into the fruit hanging portion 3 at the tip of the fruit F.

When the fruit F is suspended in this way, the weight of the fruit F and the arm portion 2 causes the arm portion 2 to rotate downward about the contact point P between the upper end 1a of the spiral portion 1 and the support column 5. But,
The upper end portion 1a of the spiral portion 1 is pressed against the support column 5 by the force at that time, while the portion 1b displaced from the upper end portion 1a of the spiral portion 1 by a half pitch is located on the support column 5 from the side opposite to the upper end portion 1a. Since the spiral part 1 is pressed, the upper part 1a of the spiral part 1 and the part 1b displaced by a half pitch from the upper part 1a are pressed against the column 5 from the opposite directions, and the friction between the spiral part 1 and the column 5 occurs. The resistance is increased and the entire hanging device A is held by the support column 5, and the fruit F is held in a state of being hung from the hanging device A. Even when the fruit F is not suspended in the hanging tool A, the weight of the arm portion 2 pushes the above-mentioned two places against the supporting pillar 5 to hold it on the supporting pillar 5, so that the hanging tool A slides down along the supporting pillar 5. There is no such thing. Moreover, since the spiral part 1 of the hanging tool A held on the support column 5 is wound around the part of the support column 5 over a half circumference, the hanging tool A does not wobble, and the hanging position of the fruit F changes even if it is fanned by the wind. There is no.

When changing or adjusting the hanging position of the fruit, the arm part 2 should be lifted slightly so that the spiral part 1 can easily rotate around the column 5, and then the arm part 2 can be moved around the column 5. Good. That is, when the arm portion 2 is slightly lifted, the upper end portion 1a of the spiral portion 1 and the portion 1b away from the upper end portion 1a and the support pillar 5 are not pressed against each other, and the frictional resistance between the spiral portion 1 and the support pillar 5 decreases. The direction of the arm 2, that is, the hanging position of the fruit can be freely changed by moving the hanging tool A.

FIG. 4 shows an example of a procedure for removing the suspender A from the column 5. In the figure, the arm portion 2 is lifted like an arrow X and the spiral portion 1 is tilted with respect to the column 5,
The state where the spiral gap B of the spiral portion 1 is exposed to the support column 5 is shown. When the spiral portion 1 is displaced to the side of the support column 5 (direction perpendicular to the paper surface) from this state, Prop 5
And the spiral part 1 is detached from the column 5, and the suspender A is removed from the column 5. When the hanging tool A is attached to the column 5, the spiral portion 1 may be fitted into the column 5 in the reverse order.

FIG. 5 shows a usage state of the hanging tool A for fruit cultivation of another embodiment. The lifting tool A of this embodiment is provided with the arm portion 2 bent from the lower end portion of the spiral portion 1 to the side opposite to the direction in which the lower end portion extends, and extends linearly to the side with a slight upward slope. ing. Also in this case, the spiral portion 1 has the pillar 5
The arm part 2 is extended to the side of the column 5.

When the fruit F is suspended, the weight of the fruit F and the arm portion 2 causes the arm portion 2 to rotate downward about the contact point P between the lower end portion 1c of the spiral portion 1 and the support column 5. However, while the lower end portion 1c of the spiral portion 1 is pressed against the support pillar 5 by the force at that time, the portion 1d displaced from the lower end portion 1c of the spiral portion 1 by a half pitch is located on the side opposite to the lower end portion 1c. The lower end portion 1c of the spiral portion 1 and the lower end portion 1c of the spiral portion 1 are pressed against each other.
The two places, that is, the place 1d displaced by a half pitch from the above, are pressed against the supporting column 5 from the opposite directions, the friction resistance between the spiral portion 1 and the supporting column 5 becomes large, and the entire suspender A is supported by the supporting column 5.
The fruit F is held in a state of being hung from the hanging tool A. Even when the fruit F is not suspended in the hanging tool A, the weight of the arm portion 2 pushes the above-mentioned two places against the supporting pillar 5 to hold it on the supporting pillar 5, so that the hanging tool A slides down along the supporting pillar 5. There is no such thing. Other matters are third
It is the same as that described in the figure.

In the two examples described above, the case where the fruit pattern F ₁ of the fruit F is directly hung on the fruit hanging portion 3 of the hanging device A has been described, but in this respect, a string is hung on the fruit hanging portion 3, The fruit pattern F ₁ may be suspended by the string.

By the way, when melons belonging to a relatively heavy category among fruits are hung for three-dimensional cultivation, it is natural that the hanging tool A is required to have a bending rigidity sufficient to withstand the weight, which satisfies the requirement. As wire material, for example, outer diameter 1.5-6
There is an iron wire with a high tensile strength of about mm and a tensile strength of about 30 to 100 kgf / mm ² , and such an iron wire can be suitably used. However, the bending workability and price of the spiral part 1 and the fruit hanging part 3 are low. Considering the above, when using a melon weighing up to about 2 kg, it is particularly preferable to use an iron wire having an outer diameter of 4 to 5 mm and a tensile strength of 60 to 80 kgf / mm ² . Further, it is desirable that the wire material forming the suspender A is prevented from rusting by plating or resin coating. Particularly, when the wire coating is resin coated, the flexibility of the resin coating causes the fruit F and the fruit pattern F ₁ Has an advantage that it is less likely to be scratched even if it rubs against the hanger A.

When the number of windings of the spiral part 1 is less than or equal to 1, the spiral part 1
The pitch of has an influence on the slipperiness when the spiral part 1 is wound around the column 5, that is, the magnitude of the holding force and the holding stability with respect to the column 5, and the larger the pitch, the larger the holding force and the less slippery and stable. The property is improved. This holding force is also related to the surface lubricity of the spiral portion 1, the outer diameter of the support column 5, the surface lubricity, and the like. That is, in the case where the spiral portion 1 is covered with polyvinyl chloride resin, polyethylene resin, rubber, elastomer or the like, or the pillar 5 is a core material coated with polyvinyl chloride resin, polyethylene resin or the like, , Their surface is hard to slip, so the holding force is large. Therefore, when targeting a melon weighing up to about 2 kg, the pitch of the spiral portion 1 should be about 2 to 5 cm, and the spiral portion 1 and the support column 5 should be covered with resin, rubber, elastomer or the like. desirable. In addition, since the holding force increases as the outer diameter of the support column 5 increases,
It is recommended to keep it to about 25 mm. Further, if the arm portion 2 is provided with an upward slope, the holding force is increased. However, this is not indispensable, and it is possible to secure a holding force that does not allow the arm part 2 to slide down from the column 5 even if the arm part 2 is horizontal or has a downward slope. If rubber, elastomer, or the like is used for the resin coating of the spiral portion 1, even if the fruit pattern F ₁ or the fruit F rubs against the spiral portion 1, it is less likely to be scratched.

The spiral portion 1 is required to have a length that can be wound around at least half the circumference of the support column 5, and if the length of the spiral portion 1 is shorter than that, the spiral portion 1 cannot be held by being wound around the support column 5. Therefore, the number of turns of the spiral part 1 is at least 1 /
Need two times. The number of windings may be one or more, but if it is too large, the attachment / detachment to / from the column 5 will have to be performed from the end of the column 5, so not only the work will be troublesome, but also the bending of the spiral part 1 will be difficult. It becomes difficult and the bending cost is high. Therefore, it is desirable that the number of turns is more than 1/2 and less than 3/2. Further, the winding diameter of the spiral portion 1 is required to be larger than the outer diameter of the supporting column 5, but if it is too large, the above-mentioned holding force will be a problem, so the limit is about 1.5 times the outer diameter of the supporting column 5. Is desirable.

The shape of the fruit hanging portion 3 is not limited to the U-shape shown in the figure, and may be bent into an N-shape. The fruit hanging portion 3 bent into the N-shape may have a fruit pattern F ₁ When the arm portion 2 is fitted in a meandering shape, the fruit handle F ₁ does not slip off from the fruit hanging portion 3 even if the upslope of the arm portion 2 is increased to increase the holding force and the holding stability. The hanging portion 3 preferably has a cross-sectional shape without corners, for example, a circular shape, and if there is a corner, the fruit pattern F ₁ may be damaged.

[Advantage of the Invention] According to the hanging tool for fruit cultivation of the present invention, since fruits such as melon can be three-dimensionally cultivated, not only the cultivation efficiency is improved as compared with the crawl cultivation, but also the fruits are attached to the pillars. The hanging work, the work of harvesting fruits, and the work of changing the hanging position of fruits can be performed much easier and faster than the case of using the conventional string. Since it is less likely to be shaken by wind or the like, there is an advantage that the situation in which the fruit is hidden behind the leaves to hinder the growth or to be scratched by rubbing against the pillars can be prevented. Further, the hanging device for fruit cultivation of the present invention has an advantage that it can be provided at a low cost because it has a simple structure that can be manufactured by bending a single wire rod.
