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

Abstract

The invention provides a manually assisted hand-held rack and pinion variable-diameter branch clamping pear girdler, including 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, the rack moves, and then drives the moving circle to be fixed on the branch of the fragrant pear. 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 into a whole 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, 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. 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 a manually assisted hand-held rack and pinion variable-diameter branch clamping pear girdler, 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.

[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. In addition to the girdling of the main trunk, each side branch of the fragrant pear must be girdled every year, and the branches growing on the side branches must also be girdled. The radius of gyration is small, and the invention patent 201410485285.2 adopts 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 achieve more space. Simultaneous rotation and tilting of two sides, the scope of use has great limitations, and it is only suitable for the trunk girdling of fragrant pears. In addition, the incision width of the girdling branches of fragrant pears ranges from 0.5 to 3.0 cm, and the incision depth ranges from 0.2 to 3.0 cm. 0.5 cm, the incision should be even, and the phloem contains more wood fibers. When the girdling knife is girdling the girdling site, there is no clamping mechanism, which will tear the phloem adjacent to the girdling site, resulting in an excessively large girdling area. The girdling of pears is not easy to heal, and nutrient delivery is blocked, which affects the growth and fruit setting rate of fragrant pears
