Artificial assistance handheld type variable diameter branch clamping electric bergamot pear girdling device

Abstract

The present invention provides a manually assisted hand-held electric pear girdler for variable-diameter branch clamping, including a handle, a spring, a rotating shaft, a clamping block, a fixed circle and a micro DC motor, and a spring is fixedly installed on the handle. During operation, The force of the spring fixes the clamping block on the branch of the fragrant pear 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 fragrant pear girders together, and 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. Driven by power, the girdling knife Take the fixed point of the handle and the connecting rod as the center of the circle, and use the fixed point to the tip of the girdling knife as the radius to make a circular motion to girdling the fragrant pears.

Description

technical field [0001] The invention relates to an artificially assisted hand-held electric pear girdler for clamping branches with variable diameters, which belongs to the field of mechanical technology. Background technique [0002] Fragrant pear saplings grow vigorously, especially at the top, and are not easy to flower. In order to achieve early fruit and high yield, girdling measures can solve the problems of strong top and weak bottom, poor flower formation, and low fruit setting rate.

[0002] Fragrant pear saplings grow vigorously, especially at the top, and are not easy to flower. In order to achieve early fruit and high yield, girdling measures can solve the problems of strong top and weak bottom, poor flower formation, and low fruit setting rate. Fragrant pear saplings grow vigorously, especially at the top, and are not easy to flower. In order to achieve early fruit and high yield, girdling measures can solve the problems of strong top and weak bottom, poor flower formation, and low fruit setting rate. Fragrant pear girdling should be applied on young trees or trees that grow vigorously and have few fruits. It can be girdled on the main trunk. For large branches that are too prosperous, it can be girdled at the base of the branches. Young trees grow vigorously, especially when the dominance of the top is strong and it is difficult to form flowers. In order to achieve the purpose of early fruiting and early high yield, the measures of girdling can solve the problems of strong top and weak bottom, poor flower formation, and low fruit setting rate. For trees aged 40 -The 50-year-old tree has the problems of being strong at the top and weak at the bottom, bare inside, and the fruiting part moves outward, resulting in a decrease in fruit quality and yield per unit area. The side branches are girdled at intervals. The growth angle of each side branch is not only the same, The distance between them 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 shaft through the expansion and contraction of the rotating oil cylinder, and only one surface can be rotated. Tilting can not realize the simultaneous rotation and tilting of multiple surfaces in the space, and the scope of use has great limitations. It is only suitable for the girdling of the main trunk of the fragrant pear. In addition, the incision width of the girdling branch of the fragrant pear ranges from 0.5 to 3.0 cm. The incision depth ranges from 0.2 to 0.5 cm, and the incision should be even. 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 If the peeling area is too large, the girdling of fragrant pears is not easy to heal, which affects the growth and fruit setting rate of fragrant pears
