Description

Automatically controlled formula jujube tree girdling device

Technical Field

The utility model relates to an automatically controlled formula jujube tree girdling device.

Background

As an economic crop originally produced in China, the jujube tree has a wide planting distribution range in China, and jujube farmers are located in more than 20 provinces such as Hebei, Shanxi, Gansu, Xinjiang, Fujian, Yunnan and the like. The red dates have high edible and medicinal values, the jujube trees are convenient to plant and manage, about more than 700 current jujube tree varieties exist in China, the red dates are the only red dates exported countries, and the overseas market potential is huge.

The jujube has more blossoms and less fruit setting, and the natural fruit setting rate is only about 1 percent, which is one of the main limiting factors of jujube trees in production. The girdling of the jujube tree can interrupt the conduction system of the phloem of the branch, so that the upper end of the branch can play a role in accumulating nutrients, the demand of the jujube tree on nutrients during flowering and fruit development can be met, and the purposes of promoting flowering and promoting fruit can be achieved. The correct use of the girdling measures can not only improve the fruit setting rate of the jujube trees and shorten the fruit setting time, but also improve the yield and the quality of the jujube trees.

The traditional girdling mode is to perform girdling by utilizing a scraper by manpower, the girdling position of the jujube tree is generally performed on a trunk which is 10 to 20 centimeters away from the ground, and then the jujube tree is gradually moved upwards every year and is girdled again at intervals of about 3 to 5 centimeters until a first main branch is reached; the strong branches can be directly girdled at a position 5-10 cm away from the base of the branches, and because the outmost old skin of the jujube trees is hard and the girdling position is usually low, a fruit grower usually needs rickets to sit on the waist or squat on the ground to perform girdling, so that the labor intensity is very high, and the waist strain is easily caused. Generally, the proper girdling period of the jujube tree with heavy flower dropping is about at the initial stage of flower filling, most of jujubes are girdled to 3-8 flowers, the jujube tree with heavy fruit dropping is to be girdled after flower filling and before the peak of fruit dropping, and for a large-scale jujube plantation, the efficiency is low, the best girdling time is easily missed, and the yield and income are influenced.

Regarding the proper girdling width of the jujube tree, the girdling width depth is judged according to the age of the jujube tree, and according to the age of the jujube tree, the girdling width depth is about 0.3-0.4 cm for young trees or weak trees, about 0.5-0.8 cm for common old jujube trees, and about 0.8-1 cm for vigorous and vigorous trees. The whole girdling opening is required to be consistent in width, smooth and flat, all phloem parts can be cut off, phloem tissue parts in the whole nail opening are removed completely, no thread is left, and no xylem is damaged, so that girdling wounds can be healed as soon as possible, and a novice not familiar with the girdling requirements of the jujube tree can not generally hold the girdling opening, so that the jujube tree body is easily damaged, or the wanted girdling effect cannot be achieved. The method is also one of the factors that the traditional girdling mode limits the scale and the industrialization development of the jujube trees.

The systematic research of Chinese on jujube tree cultivation technology is established in new China, but the development of the technology for opening the nails is not very large. Common jujube tree girdling devices on the market at the present stage mainly have three categories: small knife type, shear clamp type, double blade type, planer type; most of the devices are of pure mechanical structures, all depend on manpower and have no driving part. And at present, no electric girdling product is popularized in the domestic market, and with the increasing number of modern and centralized planted jujube gardens, the demand for a new-power girdling product is urgent and necessary.

Disclosure of Invention

An object of the utility model is to provide an automatically controlled formula jujube tree girdling device replaces artifical girdling to the jujube tree with machinery, and work efficiency is high, uses labour saving and time saving.

The utility model aims at realizing the purpose, an electric control type jujube tree girdling device comprises a shell, a direct current motor is vertically arranged in the lower part of the shell, a circular saw blade is horizontally arranged at the upper end of the rotating shaft of the direct current motor, a stepping motor is horizontally arranged at the outer side of the top part of the shell, two guide plates are arranged at opposite intervals on the top part of the shell, a flat plate is horizontally arranged between the two guide plates in a sliding way, an arc depth plate is vertically arranged at the outer side end of the flat plate, a horizontally arranged opening is arranged on the plate body at the lower part of the arc depth plate, the outer side part of the circular saw blade penetrates out of the opening, two sides of the upper part of the shell are respectively and horizontally provided with an adjusting bolt, the inner side end of the adjusting bolt is respectively abutted against two sides of the back surface of the arc depth-limiting plate, the outer side end of the flat plate is bent downwards and provided with a screw nut, and a lead screw matched with the screw nut is connected with the rotating shaft of the stepping motor through a coupler.
