Manual auxiliary handheld coil push-pull electromagnet variable-diameter branch clamping electric grape girdling device

Abstract

The invention provides a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping electric grape girdling device, including a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a push-pull electromagnet and a miniature DC motor, and a spring is fixedly installed on the handle to pull The spring set on the electromagnet fixes the moving circle on the grape branch to prevent it from rotating with the girdling knife. The handle is divided into two parts, the fixed circle is installed on the handle, and the two parts of the fixed circle are buckled together to form a complete circle , the handle opens and closes, and the fixed circle also opens and closes accordingly. There is a groove on the fixed circle, and the roller is embedded in the groove and rolls in the groove. The link passes through the center hole of the roller, and the roller rotates in a circle. The connecting rod connects the two grape girders together. The girdling handle is fixed on the connecting rod. One end of the girdling handle is provided with a girdling knife and the other end is provided with a connecting plate. With manual assistance, the girdling knife is attached to the handle The fixed point of the connecting rod is the center of the circle, and the radius from the fixed point to the tip of the girdling knife is used as a circular motion to girdling the grapes.

[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 0.5 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
