DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spike trimming knife used for trimming spikelets from main spikes and adjusting the length and number of stalks in grape spikes.

[0002]

2. Description of the Related Art Although grape consumption has increased with the expansion of cultivation area since around 1970, no significant increase has been seen since 1982. Breeding,
This is because the cultivation technology has seen a certain degree of maturity. For this reason, a series of work processes related to cultivation are now being reviewed, and interest is shifting to how to obtain stable income. This is the only way to improve the efficiency of the entire operation, from planting to harvesting related to viticulture, with the improvement of each operation.

[0003] In the whole of the above-mentioned work, the maintenance of the spikes for providing a good product is one of the works with great labor. For example, usually 3,000-15,000 bunches / 10a (R)
3,000 to 3,500 bunches / day work rate is required. Although the individual work is simple, the maintenance work of the huge amount of whole spikes as described above is a considerable effort, and improvement of the work efficiency cannot be expected in view of an aging viticulture worker. In particular, if the contents of the spike care work change as the variety improvement progresses, a stable harvest may not be maintained.

[0004] In the flower ear maintenance work (work to cut off the spikelet from the main ear and adjust the length and number of the stalks), at present, use general-purpose scissors and knives, or use the operator's own fingers and claws. ing. However, since a large number of stalks are densely formed in the flower ear, there is a problem that the scissors or the knife damages or cuts the remaining stalk. In addition, when using fingers and nails, the burden on the worker cannot be ignored. On the other hand, JP-A-09-135
No. 630 "Pulverizing Scissors" proposes small scissors that can be picked with fingertips. To assist in opening and closing the scissors, an elastic body (spring) is provided to urge the scissors in the opening direction.

[0005]

It is conceivable to reduce the size of the scissors in order to prevent damage to the spinal cord or unintentional resection. However, in the case of the above-mentioned scissors, the part that actually contributes to the excision is away from the fingertip, and the point where the cutting edge is inserted into the spike is the same as general-purpose scissors. The risk of this cannot be completely eliminated. More importantly, when using scissors, two or more fingers must be used, so that the hand holding the scissors cannot hold the actual spike. In this case, the remaining one hand must support the spikes, and the spike care work that requires both hands requires more labor than expected. Therefore, we studied to develop an easier-to-use and less labor-saving tool for maintaining the ears.

[0006]

Means for Solving the Problems In a device developed as a result of the study, a blade sickle is fixed to a finger mounting ring so as to protrude substantially in the radial direction of the finger mounting ring, and the blade of the blade sickle adjusts the bending direction of the finger. This is a flower spike grooming knife which cuts off a subspike or a fulcrum with a blade sickle by bending a finger or a wrist or swinging an arm down while the finger mounting ring is attached to the finger so as to face. The term “substantially radial direction of the finger mounting ring” as used herein means a state where the blade sickle stands upright on the finger mounting ring, and does not necessarily mean that the axis direction of the blade sickle is orthogonal to the finger mounting ring. The blade sickle is generally a single blade, and includes a curved blade sickle having a blade formed on the inner periphery, a bent blade sickle, and a straight blade sickle. In the case of a curved or bent blade sickle with a blade on the inner circumference, for example, if the blade sickle is shaken down from above, it is caught at the deepest part of the inner ear or blade sickle and does not cause a position shift, Can be cut reliably.

[0007] The spike grooming knife of the present invention is attached to one finger, and by bending a finger or a wrist or swinging down an arm, a blade sickle is pulled to cut off a spikelet or a stalk. Normally, the spikelets and spurs protrude in a substantially horizontal direction, so the resection is performed by the movement of the blade in a substantially vertical direction. That is, not against gravity
Simply by bending a finger or wrist or swinging an arm down, it is possible to easily remove the spikelets and spurs. Since the blade sickle protrudes substantially in the radial direction of the finger mounting ring, no matter how the finger is moved, the hand wearing the finger mounting ring does not touch the blade. Furthermore, the blade of the blade sickle is formed in a range from the portion fixed to the finger mounting ring to the front of the distal end portion, so that there is no fear that the blade that may hurt the hand touches the surroundings. More preferably, the tip of the blade sickle is chamfered and rounded.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a spike care knife 1 (curved blade sickle 2), which is an example of the present invention, is attached to a right index finger 3, and FIG. 2 is a front view of the spike care knife 1. Is the same flower panning knife 1
FIG.

The spike grooming knife 1 shown in this embodiment is shown in FIG.
It has an appearance as shown in FIGS. 2 and 3, and is extremely simple. The size is about the blade length of the curved blade sickle 2
30 mm, finger mounting ring 4 is 18 mm in diameter. The material can be freely selected.For example, the blade sickle and the finger mounting ring can be formed as a single resin, but usually, a separate metal blade sickle and a metal or resin finger mounting ring are connected. To manufacture. In this example, the blade sickle 2 is made of special steel, the finger mounting ring 4 is made of an aluminum plate, and the fixing portion 6 of the blade sickle 2 is sandwiched between the rounded holding pieces 5, 5 at the end of the finger mounting ring.
Stopped with rivets 7 and integrated.

The blade sickle 2 in this embodiment has a typical curved shape.
(Crescent type). A blade 9 is provided on the inner periphery in a range from the fixing portion 6 to the finger mounting ring 4 to a position just before the tip 8, and the tip 8 is chamfered and rounded. As a result, the blade scythe 2 of the present embodiment has no fear of damaging the hand even if the blade scythe 2 touches the remaining hand as well as the hand of the forefinger 3 (see FIG. 1) worn. In the case of the curved blade sickle 2, the blade 9 is directed from the top to the bottom by bending a finger or a wrist or swinging down an arm in a state where the blade 9 is addressed to the spikelet 11 or the stalk 16 of the flower ear 10. And remove it.
In addition, the shape of the blade sickle 2 includes a bent blade sickle 12 (FIG. 4) and a straight blade sickle 13 (FIG. 5), which can be used according to the preference of the worker and the spike to be harvested. .

As shown in FIG. 1, in the spike grooming knife 1 of this embodiment, the finger mounting ring 4 is fitted into the second node 14 of the right index finger 3 and the index finger 3 is fixed with the thumb (not shown). While wrist bending (snap), unnecessary spikes 1
1. Cut off the strut 16 and the main ear 17 that is too long (see Fig. 6). It is easier to attach and detach the finger mounting ring 4 to the third node 15 of the index finger 3, but it is preferable to attach the finger mounting ring 4 to the second node 14 in consideration of prevention of falling off. However, which finger or node is to be worn by the operator is freely selected by the operator, and it is only necessary that the finger-mounted ring can be stably fitted to one of the fingers or nodes of the left or right hand. .

[0012] The spike grooming knife of the present invention is one of the hands on one side.
It is only necessary to fit the finger mounting ring on the fingers of the book, and the remaining fingers can be used freely except for the remaining one hand and the finger fitted with the finger mounting ring. For this reason, since the flower spike can be firmly held using the remaining one hand and the remaining finger, the flower spike care work can be performed without damaging the flower spike and without damaging the remaining stalk. In addition, when cutting with the spike grooming knife of the present invention, the movement is small and the movement is performed only in a single direction, so that less labor is required. Thus, the spike grooming knife of the present invention increases the efficiency of the spike grooming operation.

[0013]

The spike grooming knife of the present invention greatly improves the working efficiency while being extremely simple and easy to handle. It is easy to use and can be said to be the preferred spike care tool for aged workers. Further, such a simple structure enables provision at low cost. In this way, the present invention provides an inexpensive and easy-to-use spike grooming knife, thereby improving the efficiency of spike grooming work and thereby producing grapes of excellent quality, thereby improving the profitability of fruit cultivation and the like. It contributes to the improvement of
