Grape girdling device capable of human-assistance hand-held spring plate reducing branch clamping

Abstract

The invention provides a grape girdling device capable of human-assistance hand-held spring plate reducing branch clamping. The device comprises a handle, a spring, a rotation shaft, a spring plate and a fixed circle, wherein the spring is firmly installed on the handle and the spring is a pull spring; during operations, the spring plate is clamped on a grape branch, so rotation along with a girdling cutter can be prevented; the handle is divided into two parts; the fixed circle is installed on the handle; two parts of the fixed circle are buckled together to form a whole circle; the handle is opened and closed, so the fixed circle and the spring plate can also be opened and closed under driving; a groove is disposed on the fixed circle; a roller is embedded into the groove and rolls in the groove; a linkage rod passes through a center hole of the roller; the roller makes circular rotation; two grape girdling devices are connected by the linkage rod; a girdling handle is fixed on the linkage rod; a girdling cutter is disposed on one end of the girdling handle and the other end is equipped with a linkage plate; and under manual assistance, the girdling cutter makes circular motion with a fixation point of the handle and the linkage rod as the circle center and with the distance from the fixation point to the girdling cutter tip as the radius so as to conduct girdling of the grape.

Description

technical field [0001] The invention relates to a manually assisted hand-held spring plate variable-diameter branch clamping grape girdling device, which belongs to the field of mechanical technology. Background technique [0002] Grape girdling is a cultivation technique with a long history. It has the effect of increasing fruit setting, increasing grain weight and ear weight, and promoting berry coloring and ripening. Grape girdling is to inhibit the growth of branches and prevent the outflow of nutrients. , an important measure to improve the fruit setting rate, increase the grain weight and ear weight, and promote the effect of berry coloring and ripening. It does not affect the growth of the root system. Girdling can significantly inhibit the growth of the auxiliary shoots of Kyoho grapes. The corks of new shoots Significantly improved the degree of vinification, which is of positive significance for reducing the amount of summer grape pruning, promoting grape vine fill...

[0002] Grape girdling is a cultivation technique with a long history. It has the effect of increasing fruit setting, increasing grain weight and ear weight, and promoting berry coloring and ripening. Grape girdling is to inhibit the growth of branches and prevent the outflow of nutrients. , an important measure to improve the fruit setting rate, increase the grain weight and ear weight, and promote the effect of berry coloring and ripening. It does not affect the growth of the root system. Girdling can significantly inhibit the growth of the auxiliary shoots of Kyoho grapes. The corks of new shoots Significantly improved the degree of vinification, which is of positive significance for reducing the amount of summer grape pruning, promoting grape vine filling, and improving cold resistance. Girdling can also significantly reduce the ratio of leaf buds, and girdling can reduce weight loss and rot rate during grape storage. , after grape girdling, the effect of increasing yield is obvious, and can prolong the storage time, promote the increase of flower bud ratio, and the rate of stiff buds on girdling plants is also significantly reduced. , Each side branch must be girdled every year, and the branches growing on the side branches must also be girdled. The growth angle of each side branch is not only the same, but the distance between the side branches is small, and the radius of gyration is small. Invention patent 201410485285.2 uses a motor driven by a gasoline engine, which is relatively large , the radius of gyration is large, and the inclination angle of the girdling knife is realized by the rotation of the rotary cylinder to drive the platform to rotate around the axis of rotation. Only one surface can be rotated and tilted, and multiple surfaces can not be rotated and tilted at the same time. The scope of use has great limitations. It is only suitable for grape trunk girdling. In addition, the incision width of grape girdling branches ranges from 1.0 to 3.0 cm, and the incision depth ranges from 0.2 to 0.5 cm. The incision should be even, and the phloem contains more woody fibers. When the knife is girdling at the girdling place, there is no clamping mechanism, which will tear the phloem adjacent to the girdling place, resulting in too large girdling area, difficult to heal the girdling place of grapes, hindering nutrient delivery, and affecting the growth and fruit setting of grapes Rate
