Description

Grape grain thinning mechanism {THINNING OUT DEVICE OF GRAPE BERRIES}

The present invention relates to a grape egg thinning device, and more particularly, to a grape egg thinning device for easily and quickly performing management tasks such as grape egg thinning.

In general, in the process of cultivating grapes, ancillary management tasks such as snow picking, seasoning, inducement of shoots, trimming of pines, thinning of pines and thinning of eggs are performed.

For example, in the work of thinning grapes, a method such as picking the grapes by hand by an operator or cutting the grape stalks using cutting means such as scissors was used.

However, in the method of picking grapes by hand by an operator, a series of processes of holding and removing only the corresponding grapes by inserting a finger through the grapes were very cumbersome, and a lot of time and effort had to be invested.

On the other hand, the method of thinning eggs using a cutting means requires a process of inserting the cutting blade of the cutting means grasped by hand through the gaps of the grapes, and then cutting the stem connected to the grapes.

However, the conventional method of thinning the grains using the cutting means required not only the corresponding grape grains but also unnecessary parts to be removed, so there was a hassle in the cutting operation, and the cutting blade was sharp, so that the surrounding grape grains were damaged or the operator There was a risk of being injured by the cutting blade.

In addition, in the conventional cutting means, since the cutting blade and the body are formed side by side in front and rear, when the cutting blade is changed to a horizontal and downward angle during the grape slicing operation, the handle must be changed to a large angle, so the fatigue of the operator is reduced. Was weighted.

As shown in Figs. 1 to 6, the grape egg thinning device 100 according to the present invention is for thinning the grape grains 11 of the grapes 10, and the grape grain thinning device 100 is a pair of It includes a rotating lever 110 and a clamp 120.

First, the rotation levers 110 have a certain length along the front and rear directions, and may be manufactured using a material such as metal (such as stainless steel) having a certain strength.

Here, the hinge shaft (C) is coupled through a portion of the lengthwise direction of the rotation levers 110, and both ends of the rotation levers 110 in the longitudinal direction are rotated based on the rotation center formed by the hinge shaft (C).

Further, a handle part 111 is provided at the rear end of the rotation levers 110 so that the user can rotate the rotation lever 110 while holding a hand or inserting a finger.

For example, the handle part 111 is formed through the through hole 111a in the axial direction of the hinge shaft (C) so that the user can rotate the rotation lever 110 after holding the finger in a state of passing each. I can.

Here, the handles 111 may be applied in a form in which the rear end of the rotary lever 110 is externally coated using a resin-based material.

The forceps 120 is for gripping the outer surface of the grape kernel 11 from the outside, and the forceps 120 includes a first finger 121 and a second finger 122.

The first finger 121 and the second finger 122 are connected to the front ends of the rotation levers 110, respectively, and the first finger 121 and the second finger 122 have a corresponding surface in a direction facing each other. It is equipped.

Here, the first finger 121 and the second finger 122 are integrally connected to the front ends of the rotation levers 110, respectively, and the first finger portion 121 and the second finger portion 122 are as shown in FIG. It extends to be deflected in the axial direction of the hinge shaft (C).

At this time, the first finger 121 and the second finger 122 have a shape bent in the axial direction of the hinge axis C from the front end of the rotation lever 110.

In addition, the tongs 120 extend to be deflected in the axial direction of the hinge shaft C as shown in FIG. 2, and may also extend diagonally toward the front of the rotation levers 110.

At this time, the front end of the rotation lever 110 and the rear end of the first finger 121 and the second finger 122 may be connected in a bent form by a first connection part 112 that is convex in opposite directions as shown in FIGS. 1 to 5. have.

That is, the front end (holding direction) of the first finger 121 and the second finger 122 is at right angles from the rotational direction of the rotation levers 110, that is, the axial direction of the hinge axis C. ) It has a shape oriented in the gripping direction.

The first finger 121 and the second finger 122 are interlocked with the rotation of the rotation levers 110 so as to be in close contact or spaced apart from each other.

In addition, each of the first fingers 121 and the second fingers 122 has a concave gripping groove 121 for gripping the grape kernel 11 from the outside on a corresponding surface facing each other.

The gripping grooves 121 form concave curvatures along the front and rear directions of the clamp portions 120 so as to be opposite to each other, and the gripping grooves 121 form a curvature similar to the shape of the outer surface of the grape kernel 11.

That is, the gripping grooves 121 form concave curvatures along the front and rear directions, so that the contact area with the grape kernels 11 can be widened, so that the grape kernels 11 are not easily burst by the pressing force.

In addition, since the grape kernel 11 is positioned in the front and rear direction by the gripping groove 121, the grape kernel 11 does not easily escape to the outside in the process of thinning the grape kernel 11.

For example, when the handle parts 111 are rotated in a direction facing each other, the front ends of the first finger 121 and the second finger 122 are in close contact with each other as in FIG. 1, and the gripping grooves 121 are concave curvature Are located spaced apart.

On the other hand, when the handle parts 111 are rotated (1) in opposite directions, the front ends of the first finger 121 and the second finger 122 are spaced apart from each other as shown in FIGS. 3 and 4.

Thereafter, the first finger 121 and the second finger 122 are moved (2) so that the corresponding grape kernel 11 is positioned between the first finger 121 and the second finger 122, and then the handles 111 are rotated in a direction facing each other (3). If so, the front ends of the first and second fingers 121 and 122 rotate 3 in a direction facing each other to hold the outer surfaces of the grape kernels 11, respectively.

And, at the front end of the first finger 121 and the second finger 122, the gripping end 122 may be formed to protrude, respectively, and the gripping ends 122 and the gripping groove 121 are convex in a direction facing each other. It can be connected by curvature.

At this time, the front end of the first finger 121 and the second finger 122 and the rear end of the gripping ends 122 are mutually bent by the second connection part 113 that is convex in the opposite direction as in FIGS. 1 to 3 and 5 Can be connected to.

In addition, the gripping ends 122 are formed with friction surfaces 122a capable of selectively gripping the grape grains 11 and grape stems 12, and the like on corresponding surfaces facing each other.

The friction surface 122a is a portion that is in close contact with the outer surface of the grape kernel 11 or the grape stem 12, and at least one gripping groove or gripping protrusion may be formed on the friction surface 122a.

Here, the gripping groove or the gripping protrusion has a length along the axial direction of the hinge shaft C, and may be arranged in a plurality along the radial direction of the hinge shaft C.

That is, since the gripping groove or the gripping protrusion faces the extended direction of the first finger 121 and the second finger 122, the grape kernel 11 or grape stem 12 in close contact with the friction surface 122a ) Does not easily deviate forward due to frictional force.

Meanwhile, the gripping grooves or gripping protrusions may be applied in a form in which a plurality of gripping grooves or gripping protrusions have a length and are intersected in a grid shape (not shown).

In this case as well, since the friction force in the width direction of the gripping groove or the gripping protrusion acts, the grape kernel 11 or the grape stem 12 in close contact with the friction surface 122a is not easily separated forward by the frictional force.

In addition, the first finger 121 and the second finger 122 may have a shape in which the vertical and horizontal widths of the first finger 121 and the second finger 122 gradually decrease toward the front end of the gripping end 122.

In this way, by forming the friction surfaces 122a on the corresponding surfaces of the gripping ends 122, the grape kernel 11 or the grape stem 12 having a relatively small diameter can be easily thinned out.

In addition, by forming the front end of the first finger 121 and the second finger 122 relatively narrow, the front end of the first finger 121 and the second finger 122 is easily inserted between the grape kernels 11 I can make it.

In addition, since the front ends of the first finger 121 and the second finger 122 have a narrow width, it is possible to prevent damage to the surrounding grape kernels 11.

Meanwhile, a stem gripping groove 130 opened in the axial direction of the hinge shaft C as shown in FIG. 6 may be further concavely formed on the friction surface 122a described above.

The stem gripping groove 130 has a length toward the axial direction of the hinge axis C, and the stem gripping groove 130 forms a concave curvature in the width direction to correspond to the outer surface of the stem 12 of the fruit tree 10 can do.

Since the stem gripping groove 130 covers the width direction of the grape stem 12 in both directions, the grape stem 12 in which the grape kernel 11 is heated can also be easily gripped and removed.

As a result, the present invention protrudes in a state in which the front end of the clamp unit 120 is deflected in a direction (axial direction) perpendicular to the rotation direction of the rotation lever 110, so that the rotation lever 110 does not interfere with the grapes 11 and clusters. Can be rotated, and since the clamp portion 120 is oriented in the gripping direction, the angle change radius of the handle portion 111 is small, so that ease of operation can be secured.

In addition, the present invention forms a concave gripping groove 121 on the corresponding surface of the forceps 120, so that the outer surface of the grape kernel 11 is widely wrapped with a corresponding curve, so that the grape kernel 11 easily bursts by pressing force. Without, the grape grain 11 is not easily separated in the process of separating to the rear.

In addition, according to the present invention, by forming the friction surfaces 122a on the corresponding surfaces of the gripping ends 122, grapes 11 of various sizes having a relatively small diameter can be easily thinned out.

In addition, the present invention has a form in which the width of the tongs 120 gradually decreases toward the front, so that interference with the neighboring grapes 11 can be avoided in the process of thinning the grapes 11 11) can be prevented from being damaged, and thinning work for various locations is possible.

Until now, a specific embodiment of the grape kernel thinning mechanism according to the present invention has been described, but it is obvious that various implementation modifications are possible within the limit not departing from the scope of the present invention.
