Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging apparatus for agricultural crops such as cherry tomatoes, general tomatoes and cucumbers which are cultivated in a greenhouse and whose fruits are vines.

[0002]

2. Description of the Related Art First, a method of cultivating cherry tomatoes in a greenhouse will be briefly described with reference to FIG. An attracting breath 2 is stretched across the greenhouse between the columns 1 of the greenhouse A facing each other. This invitation breath 2
In addition, a thick wire 3 called a guard wire is bundled along the depth direction P of the greenhouse, and a large number of attracting strings 4 are hung from the wire 3 close to the ridge 16 which is a planting portion of the cherry tomato T. ing. Cultivation of cherry tomatoes is performed by binding the vine 5 to the attracting string 4 at a number of points (the tying portion is indicated by S) such that the vine 5 is gradually raised toward the tip of the extended vine 5. . When the tip portion 5a of the temple 5 further extends beyond a certain length, the multiple binding portions S of the single temple 5 that are bound to the multiple attraction strings 4 are released, and The tip end portion 5a of the newly extended temple 5 was newly tied to the attracting cord 4 as well as being sewn down by a predetermined length at a time, thereby "hanging down" one by one. This "hanging down work" is a monotonous work that requires skill and skill in order to avoid damage to crops, and also requires a middle waist posture, which is painful. In addition, in the cultivation of cherry tomatoes, this "hanging down" is performed about once every two months.

[0003] In the conventional cultivation of cherry tomatoes, the "hanging down" is carried out as described above, so that the work takes a lot of time and labor, and the proportion of the whole cultivation work becomes high. , As a result, management efficiency was poor. In addition, when the vine is reattached to the attracting string, it may be broken or damaged, and the fruit may fall, which is one of the factors that reduce the yield.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to simultaneously hang down a large number of vines in a short period of time without having to retie the vines to the drawstrings, thereby increasing the efficiency of hanging work. At the same time, it is necessary to prevent vine breakage, damage, and fruit drop during hanging.

[0005]

[Means for Solving the Problem] A hanging device for agricultural products according to the present invention for solving the above problem is a worm speed reducer in an attracting brace stretched across the inside of a greenhouse between pillars of the greenhouse. And the rotary support of the suspension member is attached to another one or a plurality of induction breaths that are directly or indirectly adjacent to the induction breath to which this worm reducer is attached,
A pipe-shaped suspension member is rotatably supported by each rotation support, one end of which is connected to an output shaft of the worm speed reducer , and an input shaft of the worm speed reducer is provided below a case body of the worm speed reducer.
Is protruding, and the angular shaft formed at the tip of the input shaft
Attachment attached to the tip of the drive shaft of the electric rotating tool
The suspension member by rotating the suspension member by driving the worm speed reducer, and unwinding the drawstring excessively wound around the suspension member at a time, so that a large number of vines are collected at a time. It is characterized in that it is configured to give down.

[0006]

When the temple is extended to a certain extent or more, the attachment mounted on the drive shaft of the electric rotating tool is fitted into the square shaft portion provided on the input shaft of the worm speed reducer,
When this worm speed reducer is operated, the suspension member rotates, and a large number of attracting strings that are excessively wound around the suspension member are unwound simultaneously. As a result, a large number of vines tied to the attracting cords are hung all at once. For this reason,
Only the newly extended part of the vine is required to tie the temple to the drawstring, and it is no longer necessary to retie the vine to the drawstring as in the conventional method, and the work efficiency of `` hanging down '' is dramatically improved. At the same time, there is no risk of the vine breaking, damaging or falling fruit. In addition, the weight of the vine exerts a rotational force on the hanging member via the drawstring, but since the reducer used is a worm reducer, rotational force acts on the worm wheel shaft. However, the worm shaft does not rotate, and it is possible to prevent the attracting cord from being unwound due to the weight of the vine without providing a separate stopper device.

EXAMPLE FIG. 1 is a partial perspective view of a greenhouse A equipped with a hanging apparatus according to the present invention, and FIG. 2 is a side view of a part of a temple 5 of a cherry tomato T in the same greenhouse A. 3 is a front view of the worm speed reducer R used in the hanging device according to the present invention with one case body 11 removed, and FIG. 4 is a cross-sectional view taken along line XX of FIG. FIG. 5 is a perspective view of a portion of the worm reducer R of the hanging device, and FIG. 6 is a perspective view of a portion of the rotary support 21 that supports the hanging member 18. First, the worm speed reducer R will be described, and then the hanging device using the worm speed reducer R will be described. As shown in FIGS. 3 to 5, the worm speed reducer R has a pair of split case main bodies 11 in which a worm gear device is incorporated.
That is, the worm shaft 12 and the worm wheel shaft 13 are orthogonally supported by the pair of case bodies 11, and the worm 14 formed on the worm shaft 12 and the worm wheel 15 formed on the worm wheel shaft 13 are supported.
And are in mesh. Both ends of the worm wheel shaft 13 project from the pair of case bodies 11 by a predetermined length. In use, the worm shaft 12 is arranged in the vertical direction, and the lower end of the worm shaft 12 projects from the pair of case main bodies 11 and its tip (lower end) has
The angular shaft portion 12a is formed. A pair of case bodies 11
Mounting plates 20 are provided on both sides of the mounting plate 20.
When the pair of case main bodies 11 is integrally assembled with the pair of case main bodies 11 interposed therebetween, the worm shaft 12 and the worm wheel shaft 13 are orthogonally supported by the assembled pair of case main bodies 11.

As shown in FIG. 1, a ridge 16 is formed along the depth direction P on the soil surface in the greenhouse A, and cherry tomatoes T are planted in the ridge 16 at a predetermined interval. . The worm speed reducer R is attached to the attracting breath 2 stretched across the greenhouse between the opposing columns 1 of the greenhouse A via a pair of U bolts 17 (see FIG. 5). . In the mounted state of the worm reducer R, the worm wheel shaft 13 is along the depth direction P, and the angular shaft portion 12a of the worm shaft 12 is located below. The suspending member 18 for suspending the drawstring 4 is formed of a pipe, and as shown in FIGS. 4 and 5,
One end thereof is connected to the worm wheel shaft 13 of the worm speed reducer R via a coupling 19. Since both ends of the worm wheel shaft 13 project from the pair of case main bodies 11, the worm wheel shaft 13
The hanging members 18 are connected to both ends of each.
The U-shaped rotary support 2 is attached to each of the other attracting breaths 2 adjacent to the attracting breath 2 to which the worm reducer R is attached.
The suspension member 18 in which 1 is attached via a U bolt 17 and one end of which is connected to the worm wheel shaft 13 of the worm speed reducer R is rotatably supported by the rotation support tool 21 at several points.

A binding tool 22 is attached to the suspending member 18 via a bolt 23 (see FIG. 5), and the upper end portion of the attracting cord 4 is bound to the binding tool 22 as well as the attracting cord 4. The upper end is wound several times in excess. Since the upper end of the drawstring 4 is bound to the binding tool 22, it will not be rewound even if it is pulled. In this way, a large number of attracting cords 4 are suspended at a predetermined interval by the suspending member 18, and the lower end portion thereof reaches the vicinity of the ridge 16 where the cherry tomato T is planted. It is the same as the conventional cultivation method that the temples 5 of the elongated cherry tomatoes T are successively raised toward the tip 5a of the temples 5 and the temples 5 are bound to the attracting strings 4 at a large number of places.

When the temple 5 of the cherry tomato T extends over a predetermined length and "hangs down", it is mounted on the drive shaft 24a of the electric rotating tool 24 as shown in FIG. The attachment 25 is fitted into the angular shaft portion 12a of the worm shaft 12 of the worm reducer R, and the worm shaft 12
When is driven to rotate in the set direction, the rotation is greatly decelerated and transmitted to the worm wheel shaft 13. As a result, the suspending member 18 rotates, and a large number of the drawstrings 4 excessively wound around the hanging member 18 are unwound at the same time, and a large number of the vines 5 are simultaneously lowered. Then, when only the newly extended part of the temple 5 is manually tied to the attracting cord 4, the "hanging down" work is completed. According to an experiment conducted by the inventor of the present invention, a single worm speed reducer R simultaneously rotates the suspension members 18 having a total length of about 24 m (about 80 when converted into the number of 5 vines), and the I was able to do "defeat". Moreover, since the weight of the temple 5 of the cherry tomato T is added to the attraction string 4, the operation of the worm reducer R for rotating the suspension member 18 can be performed with a small horsepower. Furthermore, the weight of the vine 5 exerts a rotational force on the hanging member 18 via the attracting cord 4,
Since the speed reducer used is a worm speed reducer, the worm wheel shaft 13 connected to the suspension member 18 is used.
The worm shaft 12 does not rotate even when a rotational force acts on the worm shaft 12.
Therefore, it is possible to prevent the attracting cord from being unwound due to the weight of the temple without separately providing a stopper device. Multiple ridges are formed in one greenhouse, and vines of agricultural products are hung on both sides of the ridge, and one worm gear is arranged about every 20 m. Therefore, although a large number of worm gears are arranged in one greenhouse, when the worker sequentially operates each worm reducer R using one electric rotating tool described above, "Hanging" of crops can be done in a short time.

The hanging device according to the present invention can also be applied to "hanging" of other agricultural products such as general tomatoes and cucumbers which require hanging. In addition, when the "hanging" is performed as described above, the hanging vine crawls on the soil surface, which causes a disease. Therefore, form a hanging support that bends the pipe in a U shape,
Insert this temple support into the ridge at regular intervals, and if you use this temple support to hang the temple,
Prevents the above diseases.
