Manual assistance hand-held triangular block variable-diameter branch clamping electric girdling device for grapes

Abstract

The invention provides an manual assistance hand-held triangular block variable-diameter branch clamping electric girdling device for grapes. The manual assistance hand-held triangular block variable-diameter branch clamping electric girdling device for the grapes comprises a handle, a spring, a rotating shaft, a triangular clamping block, a setting circle and a miniature direct current motor. The spring is fixedly installed on the handle, the force of the spring fixes the triangular block firmly on branches of the grape tree to prevent the triangular block from rotating with a girdling knife, the handle is divided into two parts, the setting circle is installed on the handle, two parts of the setting circle are buckled together into a whole circle, when the handle is opened and closed, the setting circle is opened and closed in a follow-up mode, a groove is formed in the setting circle, a roller is embedded in the groove and rolls in the groove, a link rod runs through a center hole of the roller, the roller rotates in circles, the link rod connects two grape tree girdling devices, a girdling handle is fixed on the link rod, one end of the girdling handle is provided with the girdling knife, and the other end is provided with a link plate. Under the manual assistance, the girdling knife make a circular motion to girdle the grapes, with the fixing point of the handle and the link rod as the center of the circle and the distance between the fixing point and the knife point of the girdling knife as the radius.

Description

technical field [0001] The invention relates to a manually assisted hand-held electric grape girdling device for clamping branches with variable diameter triangular blocks, 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, ...
