Description

  The present invention is in the middle of growing to manage the shipping quality of vegetables and fruit trees, and in the work of removing fruits such as vegetables and fruit trees just before shipping, the vegetables, fruit trees, etc. used for the picking operation of the fruit and vegetable grains to remove the fruits It is related with the granulator of this.

  Conventionally, for example, in grape cultivation, it is important to improve the fruit quality, and in particular, the degree of sugar content, coloration, and the like are closely related to the amount of fruit, and excessive fruit production has already deteriorated the quality. Are known. In particular, excessive fruiting results in poor coloring and causes ripening. Therefore, it is necessary to adjust the yield more efficiently by looking at the state of individual trees and the weather conditions of the year. The yield is calculated by “number of tufts × bundle weight”, and the tuft weight can be calculated by “number of grains × grain weight”, and is performed by adjusting the size of the tufts (grabbing) and the number of tufts (pulping).

  In particular, the grain-removing operation that thins and removes the seeds in the case of grapes is intended to limit the number of seeds to the target size, to adjust the shape of the bunches, to align the size of the seeds, and to increase the commercial value. It is an important work. This graining work is the most labor-intensive work among the cultivation of grapes, and is carried out after limiting the number of tufts (plucking).

Such a grain-removing operation is a very important operation that is also carried out for the cultivation of vegetables such as tomatoes, eggplants, and watermelons in addition to fruits such as grapes, peaches, pears, apples, plums, and cherries. For example, Patent Document 1 discloses a scissor scissors used for a refining operation in which an immature small fruit granule is removed from a cocoon in which a large number of fruit grains are tufted or an extra fruit is excised.
JP-A-9-135630

  However, the picking work for these vegetables, fruit trees, etc. is generally performed by scissors as in Patent Document 1 or by cutting or picking the fruits to be picked one by one using tweezers. Especially in the case of grapes, the harvesting operation is performed at a time when the fruiting is not so large. In order to adjust the shape, the squeezing operation to remove immature small berries or excess berries from the bunches of many bunches of tufts at appropriate times. Is done. Therefore, although scissors are easy to enter, the work efficiency is increased, but when the fruit is large, there is a problem that scissors are difficult to enter and the workability is remarkably lowered. In such a case, there arises a problem that the graining cannot be performed, or the fruit that must be left behind is damaged. In addition, since the general tweezers have a shape suitable for medical use, a portion for pinching the nut is thin, and an anti-slip unevenness is provided on the inner surface of the tip.

For this reason, when grapes are squeezed, they are often crushed. When squeezed, fruit juice flows out, contaminates the fruit that must be left behind, and lowers the shipping quality. For this reason, the fruit that must be left adjacent is scratched, and the fruit grows with this scratch remaining and deteriorates the shipping quality. Therefore, careful work is required, and skill is required.

Also, with conventional tweezers, the part that is operated by hand and the part that holds the plucking are in a straight line, and in the case of grapes, the tweezers are perpendicular to the tuft to pluck the tuft on the operator's head. In order to perform graining in a posture, excessive fatigue was given to workers due to the large amount of graining.

  Therefore, the present inventor has made the present invention as a result of earnest research in view of the above problems, and the feature thereof is that the tip of the tweezers that is often used in the graining operation is shaped to be suitable for graining. It was devised, and it prevents fruit damage and contamination with fruit juice and provides a operability good sizing tool.

  In the present invention, first of all, the part that pinches the squeezed grain is widened, and the inner part is molded in a concave shape so as to match the outer shape of the fruit. When the clamping surface pressure due to the clamping force applied to the granulation is significantly reduced, breakage of the granulation can be prevented.

Second, when the operator uses the conventional tweezers to squeeze, the part to be held and the part to grip the sieving are in a straight line, so that the tweezers do not come into contact with the top and bottom of the squeezed grain so that they are perpendicular to the grape bunches. A special working posture was required, and when carrying out the graining of the worker's head, the hand had to be lifted extremely.
In the present invention, as shown in FIG. 1, the angle “θ” is added to form a sickle-necked shape, so that a granulation posture can be achieved by lowering the height of the hand during operation. Work can be done without getting tired during the graining process.

  Thirdly, when grapes are ripened, the fruit is generally large, and the fruit is often in close contact with each other. In order to grasp the grain, it is necessary to insert a conventional sharp tweezer between the adjacent fruit. there were. For this reason, the tip of the tweezers will be damaged steadily, and in many cases, the quality of the grape shipment will deteriorate. In this proposal, the tip portion (7) shown in FIG. 1 has a wider portion for gripping the fruit set of claim 1, so that the tip part can be gently shaped into an R shape, Even if it is inserted in between and brought into contact with the fruit, the graining operation can be easily performed without damaging the fruit. In addition, the “neck” of the part that grips the granulation is thin, and when the granulation is sandwiched, even if it is sandwiched with an excessive clamping force, the “neck” is thin and elastically deforms, releasing the clamping force and damaging the granulation It is possible to grab the granulation with the optimum clamping force without any problems.

  According to the invention of claim 1, by widening the part that grips the fruiting, and forming the inside concave so as to correspond to the outer shape of the fruiting, the contact area with the parting of the part that grips the granulation is large, Even if a large sandwiching load is applied, it is possible to prevent the granulation from being broken and the juice from flowing out. For this reason, it will be possible for an unskilled worker to easily perform the granulation work that has conventionally required skill.

  According to the invention of claim 2, the fruit gripping part is bent and formed into a sickle neck with an angle (θ), so that the operator can hold the hand as shown by 00120 compared to conventional tweezers without an angle. It is possible to work by lowering, and significant work fatigue can be prevented.

  According to the third aspect of the present invention, the tip of the part that grips the fruit is gently tapered, and the operation part side of the part that grips the fruit is also narrowed, so that even if it is inserted between adjacent fruit Therefore, the graining operation can be easily performed without damaging. In addition, when pinching is carried out, even if it is pinched with an excessive pinching force, the “neck” is thin and elastically deformed, so that it can be grabbed with an optimal pinching force without damaging the pinch. For this reason, even if an unskilled worker grasps the granulation with an excessive load, the effect of claim 1 can be further enhanced.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 and 2, the granulating instrument P of the present invention has a tweezers shape in which gripping members (1) and (2) configured by a pair of left and right elastic bodies are integrally joined at a base (3). The distance between the tips (5) can be reduced by picking the part (4) for operating the gripping members (1) and (2) with the fingers of the operator. Further, when the picking force is released, the distance (5) can be restored to the original by the elastic force of the gripping members (1) and (2).

  At the tip of the gripping members (1) and (2), a gripping part (6) for granulation is integrally formed. This gripping part (6) is formed in the shape of a dish or spoon that bulges outward, and its vertical width is wide (B2) according to the size of the granulation, and its cross section is the outer shape of the granulation As shown in FIG. 3, it is formed in the shape of a concave surface (R) that bulges outward.

  The neck portion (B1) of the gripping portion (6) is elastically deformed even when an excessive load is applied when gripping the granulation, and the members (1) and (2) The neck (B1) is extremely narrow with respect to the width (B4) and the grip portion (6).

1 to 2 show an embodiment of a granulating instrument P according to the present invention.
The gripping members (1) and (2) composed of a pair of left and right elastic bodies are integrally formed with the base (3), and the operator performs granulation as shown in FIG. 1 in the middle from the base (3) to the tip. The part (4) for performing the operation of picking up is widened in order to relieve pain and the like in the operator's hand when picked.

  Then, the widths of the gripping members (1) and (2) are gradually narrowed toward the gripping part (6) that grips the nut from the part (4) that performs the operation, and the neck part of the gripping part (6) is minimized. Form the width (B1), and then gradually increase the width from the gripping part (6) to the width (B2), then gradually reduce the width toward the tip (7), and the tip (7) will not be sharp. It has a semicircular shape.

  In addition, the gripping part (6) is bent and formed in a sickle neck shape with an angle (θ) inclined with respect to the part (4) to be picked, thereby facilitating the picking operation.

The portion (4) to be picked is provided with a plurality of non-slip irregularities (T) in the form of a streak so as to prevent the slipping and make the picking operation reliable and easy.
Further, the lower part (3) is provided with a metal fitting (8) for fixing the string so that it can be suspended from the operator's neck or the like by a string or the like.

Explain how to actually use.
As shown in FIG. 8, the operator can pinch and release the part (4) operated by the instrument P with the thumb and forefinger, and can change the distance (5) between the members (1) and (2). To hold. The operator visually holds the bunch of grapes with the other hand, selects the fruit to be grained while rotating, and picks the grain with the grasping part (6) of this instrument P so as not to damage the adjacent fruit. Grab the granulation by pinching, twisting and pulling. In general, grapes are often cultivated on shelves, and the bunches of grapes are made at a height higher than the eyes of the workers. With conventional tweezers, the workers hold their hands above their shoulders. Was forced to. The granulator of the present invention has an operation part (4) and a grip part (6) bent at an angle (θ) sickle shape, so that it can work in a working posture with its hands lowered, and work fatigue is reduced. It has been reduced.

Also, the tip of the conventional tweezers (B3) is narrow and sharp at the tip, so it is highly likely that the adjacent seed will be damaged when inserted into a close fruit, and when the granule is grasped In many cases, too many squeezed granules were crushed. Since the tip part (7) of the gripping part (6) is gently shaped in an R shape, the graining device of the present invention has a gentle R shape. It does not hurt the adjacent fruit. Also, when grabbing, the gripping part (6) has a wide width (B2) even if the gripping force is slightly increased, so the granulation is not crushed. Since the work can be easily performed even by an amateur worker, it is easy to secure the worker for the picking work during the busy season.

As described above, according to the graining device of the present invention, it is possible to easily and accurately remove immature small grains and excess grains from a basket in which a large number of grains are densely attached. Can be granulated. And the siphoning operation which arranges the magnitude | size of the fruit grain of a cocoon uniformly, or arranges the shape of a cocoon can greatly facilitate and speed-up.
Moreover, when performing the picking work of the cocoon, it is possible to accurately prevent the fruit that should be left in the cocoon from being damaged or the fruit that should be left in the cocoon to be mistakenly picked.

The present invention can be applied not only to grapes but also to cultivating vegetables such as peaches, none, apples, plums, cherries, tomatoes, eggplants and watermelons.
