Manually-assisted handheld gear-rack variable-diameter branch clamping grape girdling device

Abstract

The present invention provides a manually assisted hand-held rack and pinion variable-diameter branch clamping grape girdling device, which includes a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a gear, a rack and a servo motor, and a spring is fixedly installed on the handle. The servo motor drives the gear to rotate, the gear meshes with the rack, and the rack moves, and then drives the moving circle to be fixed on the grape branch. The handle is divided into two parts, and the fixed circle is installed on the handle. The two parts of the fixed circle are buckled into 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 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. The fixed point of the connecting rod is the center of the circle, and the radius of the knife tip from the fixed point to the girdling knife is used as a circular motion to girdling the grapes.

Description

technical field [0001] The invention relates to a manually assisted hand-held pinion and rack variable-diameter branch clamping grape girdler, 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 filling, ...

[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. , the effect of increasing yield after grape girdling 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. Not only are they the same, but the distance between side branches is small and the radius of gyration is small. In addition to the girdling of the main trunk, each side branch must be girdled every year, and the branches growing on the side branches must also be girdled. The spacing is small and the radius of gyration is small. Invention patent 201410485285.2 uses a motor driven by a gasoline engine, which has a large volume and a large radius of gyration. The inclination angle of the girdling knife is realized by rotating the platform around the rotating shaft through the expansion and contraction of the rotating oil cylinder. Only one surface can be rotated and tilted, and it cannot Realize the simultaneous rotation and tilt of multiple surfaces in the space, and the scope of use has great limitations. It is only suitable for the trunk girdling of grapes. 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 ~0.5 cm, the incision should be even, and the phloem contains more wood fibers. When the girdling knife is girdling the girdling, there is no clamping mechanism, which will tear the phloem adjacent to the girdling, resulting in an excessively large girdling area. The girdling of the grapes is not easy to heal, and the nutrient delivery is blocked, which affects the growth and fruit setting rate of the grapes
