Description

A simple fruit tree girdler

technical field

The utility model relates to a special daily pruning tool for fruit trees, in particular to a simple and simple fruit tree girdling device.

Background technique

Girdling, that is, ring peeling, is to cut one or several rings across the trunk, cut off the phloem screen as deep as the xylem, destroy the normal nutrient exchange between the upper and lower parts of the tree, and prevent the downward transport of nutrients. The girdling operation of the trunk can inhibit vegetative growth and promote reproductive growth. It is an important technical measure commonly used in fruit tree production to promote flowering, control crowns, and increase fruit setting rate.

But at present, in the daily pruning management of fruit trees, pruning knives, grafting knives, or even sickles are commonly used for circumcision operations. On the one hand, peeling is extremely inconvenient and the work efficiency is low. On the other hand, the cutting depth is difficult to control, and it is easy to damage the trunk. xylem.

For example, the utility model patent named "A Kind of Fruit Tree Girdling Device" declared by Hao Mingmiao (authorized announcement number: CN202773506 U) and the utility model patent named "A Kind of Girdling Device" declared by Liu Mengtian (authorized announcement number : CN204104394 U) are all very valuable inventions, which can accelerate the girdling speed, but also have weak points, such as the previous girdling device needs to be girdled twice before the bark can be taken off, reducing work efficiency; A girdling device has complex structure, high manufacturing cost and troublesome operation, which is unfavorable for popularization and application in a large area.

Contents of the invention

In view of the above problems, the utility model has designed a simple and easy fruit tree girdler, which has a simple structure, easy to operate, efficient and safe novel fruit tree girdler.

In order to achieve the above object, the utility model adopts the following technical solutions:

A simple fruit tree girdling device, characterized in that it includes a main rod and a girdling knife, the girdling knife is bent into a U-shaped structure by a metal blade, and the girdling knife passes through the middle of the U-shaped two ends and the main rod after being inclined. The lower parts are fixedly connected together, and the angle range between the front edge of the girdling knife and the main rod after the connection is 45°-75°, and the inside of the girdling knife is connected to the front and back to form the discharge hole of the bark.

Further, the above-mentioned main rod is made of metal, which forms an integral structure with the girdling knife through welding.

Further, the above-mentioned main rod is set in a cylindrical shape.

The front end of the main rod of the utility model is the hand-held part for operation, and the middle and lower part of the main rod is connected with a girdling knife arranged obliquely. For girdling and peeling operations, the girdling knife is internally connected to the front and rear ends to discharge the bark.

When in use, the blade of the girdling knife and the main rod are stuck on the trunk to be girdled, and the main rod and the girdling knife are pressed so that the blade of the girdling knife is inserted into the skin of the trunk of the fruit tree, and then rotated clockwise for one circle. The fruit tree bark of the corresponding width can be peeled off.

To sum up, the utility model has simple structure, low cost, easy to carry, easy to operate, saves time and effort, and at the same time, the peeled bark can be smoothly discharged from the girdling device, which can well ensure the quality of girdling.

detailed description

As shown in FIGS. 1 and 2 , a simple fruit tree girdling device includes a main rod 1 and a girdling knife 2 .

The girdling knife 2 is bent into a U-shaped structure by metal blades such as stainless steel. The girdling knife 2 is tilted and connected to the middle and lower part 11 of the main rod 1 through its U-shaped ends. After the connection, the girdling knife 2 front The angle a between the upper blade 21 and the main rod 1 ranges from 45° to 75°. During assembly, the inclination angle of the girdling knife 2 can be adjusted according to actual needs to obtain a corresponding girdling width, such as 0.2 cm, 0.3 cm or 0.4 cm etc. The inside of the girdling knife 2 is connected to the front and rear ends to form an outlet 22 for bark after girdling.

The main rod 1 is made of metal material, and forms an integral structure with the U-shaped ends of the girdling knife 2 by welding.

The front end of the main rod 1 of the above structure is the hand-held part 12 during operation, and the middle and lower part 11 of the main rod is connected with the girdling knife 2 arranged obliquely, and the girdling knife 2 has the functions of girdling and peeling concurrently, wherein The knife edge 21 at the front portion of the knife 2 performs ringing and peeling operations, and the discharge hole 22 inside the ringing knife 2 is used to discharge the bark.

During use, the girdling knife blade 21 and the main pole 1 are stuck on the trunk 3 that needs to be girdled, and the main pole 1 and the girdling knife 2 are pressed properly so that the sharp blade 21 of the girdling knife is inserted into the epidermis of the fruit tree trunk 3 , then the operator rotates the girdling knife 2 in a clockwise direction through the hand-held part 12 of the main rod 1, and the sharp U-shaped girdling blade 21 can peel off the girdling of the fruit tree trunk 3 at this time, and the The fallen trunk skin 31 is discharged from the discharge opening 22 in the girdling knife 2 .

Here, in order to reduce the frictional resistance during girdling operation, the main rod 1 is set in a cylindrical shape, so as to reduce the contact area between the main rod 1 and the trunk 3 and ensure the smooth rotation of the main rod 1 around the trunk 3 .

In summary, the utility model is a simple fruit tree girdler, which has the characteristics of simple structure, low cost, easy to carry, easy to operate, time-saving and labor-saving, and the stripped bark can be smoothly discharged from the girdler. Can well guarantee the quality of girdling.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change or modification made to the above embodiments according to the technical principle of the utility model, Still belong to the scope of the technical solution of the utility model.
