Abstract

The present invention provides a fruit defoliating and thinning device for fruit trees which is light in order to perform flower-removal, defoliation and thinning fruit with one hand or both hands, is conveniently operated and is useful for the defoliation and thinning fruit of a tall fruit tree beyond reach. The fruit defoliating and thinning device for fruit trees of the present invention comprises: a head part (10) in which a rotary blade (16) is attached; a driving shaft housing (31) in which the length of the fixed head part is extended; a motor part (50) which is connected to the driving shaft housing (31); and a battery part (60) which is connected to the motor part. The motor part (50) and battery part (60) include a handle (40) installed in a circular shape and enables an operator to work with one hand. The handle (40) includes an operating switch (41) and enables the operator to control the operation and rotation of a blade when the operator performs defoliation and thinning fruit. The present invention enables the operator to conveniently perform defoliation and thinning fruit by using the fruit defoliating and thinning device comprising the head part equipped with an extended blade in a tall fruit tree with one hand or both hands. When the operator uses the fruit defoliating and thinning device, work efficiency and work speed are sharply increased since the operator is able to perform operation in a range which is broader with 1-3 m.

Description

Fruit defoliating and thinning device for use in fruit trees}

The present invention is a portable, easy to carry golden hand, ie red fruit and red fruit, which is easy to carry the red leaf and red fruit in the fruit tree by the blade attached to the end of the drive shaft rotated by the motor to operate the motor is small by using a battery It is about.

The golden hand is compactly made light in weight so that the worker can work with one hand when using a ladder or the like in an orchard such as apple or pear.

The present invention relates to a red fruit and a red fruit used in the process of cutting red flowers and red fruits in the same cluster, leaving more fruit or fruit among the flowers or fruits in the same cluster at the time of fruiting or fruiting. will be. It can also be used as a red leaf used in red leaf (때 葉) work when you want to remove the leaves around the fruit to facilitate coloring at the time when the fruit is colored after the fruit is large.

The blade of the red fruit or red leaf device of the present invention is configured to be operated by a motor driven by the battery, so that the portable and easy to carry out red and red leaf work, and can maximize the efficiency of the work.

Apples and pears bloom 6 ~ 8 flowers in the flower buds of the cluster, and if they bear fruit, 6 ~ 8 fruits will run in a single fruit. Leave only one of the most faithful to the cluster and remove the rest.

On the other hand, when the number of flowers per fruit tree is too much, some of them are removed from the middle in order to leave the fruit suitable for the size and age of the tree.

In addition, as the fruit grows, sunlight is sufficiently irradiated on the fruit to facilitate coloring. When there are too many leaves around the fruit, the leaves cover the fruit, which results in poor pigmentation and deterioration of the fruit's marketability.

Conventional redness, redness and methods include spraying the medicine to the flowering or working directly by hand, and if the fruit bears a method of cutting with scissors.

However, when the weather is not good, such as during rainy days, the effect of spraying the drug is very low. When the weather is good, only about 40% of the effect is obtained. Because the enemy should be due to the back and the efficiency of the enemy and enemy is falling, there is a problem that the double time and manpower is consumed.

Instead of spraying chemicals on the flowering plants, the flowers can be picked up by hand, and in this case, 4 ~ 6 times of cleaning should be done per single flower. In addition, when the icing process has to be scissored about 3 to 4 times per song, there is a problem that a lot of time and manpower is consumed in the work.

In the case of removing flowers with ordinary scissors, there is a problem that the stem of the flower (fruit stem) left by the blade is damaged when the handle part is opened after cutting the flower with the scissors. .

After fruiting, the red fruit processing process is performed with small scissors to remove the cutting process. Since the average of three times of cutting per piece, the worker's hand and wrist feel a great fatigue, which makes it difficult to work for a long time. there was.

On the other hand, when the red fruit or hand with scissors, if the fruit is large, there is a problem that the enemy and the fruit is not easy because the hands or scissors do not touch the far place or the upper part of the fruit.

Domestic Patent Publication No. 20-0252952 (2001.10.23.)

The present invention has been made to improve the above-mentioned problems, the object of the present invention is to provide a light and easy to operate red leaves and red fruits so that the worker can be red, red and red with one or two hands.

Another object is to allow red leaves and red fruits to reach out of reach of workers in the case of large trees.

In order to achieve the object as described above, the fruit lodge and red fruit of the present invention is a drive shaft housing 31 and the drive shaft housing 31 and the drive shaft housing is extended to a long length to fix the head portion with the rotary blade 16 attached The motor unit 50 connected to the 31 and the battery unit 60 connected to the motor unit. The handle 40 is installed in the motor unit 50 and the battery unit 60 in an arc shape so that the worker can work with one hand.

An operation switch 41 is installed in the handle 40 to allow the operator to adjust the strength of the blade operation and blade rotation when the worker makes red leaves and red fruits.

The blade 16 of the fruit lodge and red fruit in accordance with the present invention is operated by the battery power of the battery unit 60, the battery drives the motor mounted on the motor unit 50, the rotational force of the motor drive shaft housing (31) is transmitted by the drive shaft 30 extending to the blade 16 to the inside, the blade 16 is a rotary shaft between the upper guide 11 and the lower guide 12 at the end of the drive shaft housing 31 ( 15) is fixed and installed. The rotational force transmitted from the drive shaft 30 to the blade 16 is driven by the motor shaft bevel gear 13 mounted on the drive shaft 30 meshed with the blade shaft bevel gear 14 fitted to the rotation shaft 15, and the blade shaft. Bevel gear 14 is to rotate the blade (16).

When the power source of the fruit tree and the red fruit in accordance with the present invention (ON), the drive shaft 30 is rotated according to the operation of the motor, the power is transferred step by step by the rotational force of the drive shaft 30 to rotate the blade 16 Done. The rotational force of the blade 16 removes unwanted flowers and fruits on the fruit trees or fruit trees of the fruiting tree.

However, the rotation of the blade 16 can be removed to leave other flowers and fruits to be left, so in order to leave the necessary flowers and fruits, cover the blades rotated with protective caps (20a, 20b) while protecting the flowers and berries are not desired Remove flowers and fruits.

The present invention relates to a light and easy to operate red leaf and a red berry that the worker can red, red and red with one or two hands. Alternatively, the two hands can be used to facilitate red, red and red leaves easily.

In the case of using the red leaf and red fruit of the present invention can work in a wider range of 1 to 3m wider than the case of using the red leaf and red fruit using bare hands or scissors, so the work efficiency is good because there is no need to change the worker position much The speed of work can be greatly increased, which can greatly reduce the manpower per unit area or fruit tree.
