Description

[Detailed description of the invention] The present invention relates to an improvement in a fruit thinning machine.

Conventional fruit thinning machines either have cutting blades protruding in the diametrical direction on the outside of the rotary protection tube, or push the fruit stems that should be left out of the rotation trajectory of the rotary blade plate using a guide plate, or Since the ridge of the fruit is drawn into the blade of the rotating disk blade using a curved guide plate, both have the drawback of damaging or cutting the fruit that should be left. ``In order to eliminate the above-mentioned drawbacks, the present invention fixes a protective tube to the body, and arranges an inner fruit cutting tube and an outer fruit cutting tube in a concentric cylindrical shape on the outside of the protective tube. The inner and outer cantilever cutting tubes are made to protrude from the tip of the fixed protection tube through an operating lever pivotally connected to the body, and the interlocking device in the body is driven, and the inner canopy cutting tube is cut through the interlocking device. The cylinder is rotated, and fruits other than those protected by the fixed protection cylinder are thinned by both the inner and outer fruit cutting cylinders.

Hereinafter, the present invention will be described in detail with reference to drawings showing embodiments.

In the figure, reference numeral 1 denotes a fixed protection tube, which is provided with an elastic lining 2 made of rubber or rubber-like material on its entrance edge and inside, and is attached to a body 4 via a fixed shaft 3.

The body 4 includes a nose portion 5 that surrounds the fixed protection tube 1 in a cylindrical shape, and a hollow grip portion 6 that holds the nose portion 5 at an appropriate angle. A motor 7 and a group of interlocking gears 8 driven by the motor 7
, 9, 10, 11, 12 is built-in. The gear 12 at the output end of the exercise device 13 is formed into a wide medium. Reference numeral 14 denotes an inner cylindrical cutting tube arranged outside the fixed protection tube 1, and has one or several sword bodies 15 (two sword bodies 15 are shown in FIG. 1) at the closed end. (shown in the figure) is provided protrudingly provided along the cylinder axis of the inner cypress cutting cylinder 14 in all directions, and it is optional whether or not the blade part is provided on the sword body 15.

16 is the same D for fixing the inner helical cutting tube 14 to the outside of the protecting tube 1.
It is a cylindrical shaft that supports the cannula, and is supported by a fixed shaft 3.

17 is a passive gear fixed to the end of the sleeve shaft 16,
It meshes with the wide medium gear 12 at the output end of the interlocking device 13 in a freely movable manner.

Reference numeral 18 denotes an outer fruit cutting tube, which is equipped with a serrated blade 19 having a chevron or wave shape at its open end.
It is optional whether or not to provide the blade part 9.

The rear end base of the outer fruit stalk cutting tube 18 is attached to the cannula shaft 16 for supporting the inner fruit stalk cutting tube 14 via a ball bearing 20.
As a result, the outer pedicle cutting tube 18 slides in the key line direction of the inner pedicle cutting tube 14. 2
Reference numeral 1 denotes a frog-like operating lever that is pivotally connected to the grip portion 6 of the body 4 via a pivot shaft 22, and a long hole or notch formed at the tip of the crotch is provided protruding from both sides of the outer currant cutting tube 18. Further, the tip of the pin 23 is engaged with a guide groove formed horizontally on the inner surface of the nose portion 5 of the body 4.

As a result, the outer fruit cutting tube 18 is held unrotatable, and the inner fruit cutting tube 14 is moved forward and backward along the fixed protection tube 1 via the operating lever 21 and the ball bearing 20. It can be done. Reference numeral 24 denotes a return spring inserted between a spring receiver 25 provided on the grip portion 6 and the operating lever 21, and the operating lever 21 is rotated clockwise around the pivot shaft 22 to release the outer fruit cutting tube 18. and the inner apple cutting tube 14 are urged to retreat into the nose portion 5.

Reference numeral 26 denotes a switch for the motor 7 mounted within the grip portion 6, and is opened and closed by a pressing hole 29 formed at the lower end of the operating lever 21.

Reference numeral 28 denotes a female connector attached to the lower end of the grip portion 6, to which a battery, lightning source, etc. (not shown) can be connected.

29 is a bearing metal that supports the outer apple cutting tube 18 within the nose portion 5.

Since the fruit thinning machine of the present invention is configured as described above, a battery or a power source is connected to the female connector 28, and the fruit to be left is selected from among a plurality of fruits, such as apples, radially attached to one location on a twig. Select one fruit, cover it with the fixed protection tube 1, and push the edge of the fixed protection tube 1 toward the base of the fruit ridge. All of the fruits are laid down horizontally at the closed edge of 1, and the fruits to be left enter the fixed protection tube 1 and are protected.

Since the elastic lining 2 is provided on the Sekiguchi green part and the inside of the fixed protection tube 1, the fruit to be left will not be damaged in the process of getting into the protection tube 1. Next, when the operating lever 21 is pulled with a finger against the return spring 24, the passive gear 17 moves over the wide and medium gear 12 of the interlocking device 13.
Both the outer ridge cutting tube 18 and the inner ridge cutting tube 14 slide forward along the fixed protection tube 1, and the tip of the outer pedicle cutting tube 18 projects further forward than the tip of the individual protection tube 1. Then,
At the same time that the fruit stem, which has been laid down sideways as described above, enters the trough of the serrated blade body 19, the pressing member 27 of the operating lever 21 closes the switch 26 in the grip part 6, and the motor 7
Since the inner fruit cutting tube 14 is rotated through the movement device 13 including the drive gear IT and the passive gear IT, the fruit berries are cut and fruit thinning is performed by the cooperation of the serrated blades 19 and 15. Although the drawings show an embodiment in which the fixed protection tube 1 is fixed to the body 4 via the fixed shaft 3, and the mantle tube shaft 16 for supporting the inner fruit cutting tube 14 is attached to the fixed shaft 3 as a broken line, The fixed shaft 3 and the mantle shaft 16 are omitted, and the fixed protection tube 1 is directly fixed to the body 4, and the inner stalk cutting tube 14 is arranged outside the fixed protection tube 1 in the same D cylindrical shape. Good too. As can be easily understood from the above explanation, when using the fruit thinning machine of the present invention, the protection tube is fixed and has an elastic lining, and the fixed protection tube is further provided with a rotary tube arranged in the same D cylindrical shape. By making the inner fruit stem cutting tube which is rotatable and the outer fruit stem cutting tube which cannot be rotated move forward and backward along the fixed protection tube, there is no damage to the fruit that should be left during fruit thinning. As long as the fruit to be left is placed in the fixed protection cylinder, the fruit thinning operation can be completed by pulling the operating lever once, and the fruit to be left will not be accidentally cut. This effect can be achieved.
