Artificial auxiliary handheld bergamot pear tree girdling device achieving variable-diameter branch clamping through push-pull electromagnets

Abstract

The invention provides an artificial auxiliary handheld bergamot pear tree girdling device achieving variable-diameter branch clamping through push-pull electromagnets. The device comprises a handle, a spring, a rotating shaft, a movable circle, a fixed circle and the push-pull electromagnets; the spring is fixedly installed on the handle and is a tension spring, and when operation is conducted, the movable circle is fixed to a branch of a bergamot pear tree through springs arranged on the push-pull electromagnets to prevent the branch from rotating along with a girdling knife; the handle comprises two parts, the fixed circle is installed on the handle, two parts of the fixed circle are buckled together to form a completer circle, the fixed circle is opened and closed along with opening and closing of the handle, a groove is formed in the fixed circle, and a rolling wheel is embedded into the groove and rolls in the groove; a connecting rod penetrates through center holes of the rolling wheels, the rolling wheels do circular rotation, two bergamot pear tree girdling devices are connected together through the connecting rod, a girdling handle is fixed to the connecting rod, the girdling knife is arranged at one end of the girdling handle, a connecting plate is arranged at the other end of the girdling handle, and by means of artificial auxiliary, the girdling knife does circular motion by taking the handle and connecting rod fixing point as a circle center and taking the distance between the fixing point and the knife tip of the girdling knife as the radius to girdle the bergamot pear tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet 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. 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...

Problems solved by technology

[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 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 problem of being strong at the top and weak at the bottom, bare inside, and the fruiting part moves outwards, resulting in a decrease in fruit quality and yield per unit area. Fragrant pears must be girdled every year in addition to the main trunk. The branches growing on the side branches should also be girdl
