Artificial auxiliary hand-held type wrench variable-clamping electric girdling device for bergamot pear branches

Abstract

The invention provides an artificial auxiliary hand-held type wrench variable-clamping electric girdling device for bergamot pear branches. The artificial auxiliary hand-held type wrench variable-clamping electric girdling device for bergamot pear branches comprises a handle, a spring, a rotating shaft, a wrench, a constant circle and a micro direct-current (DC) motor, wherein the spring is fixed on the handle and the spring is tension spring; when operating, the wrench is firmly fixed on the pear branches by the acting force of the spring in order to prevent rotation of wrench with a girdling knife; the handle is divided into two parts, and the constant circle is installed on the handle; the two parts of the constant circle are bound together to form a whole circle; as the handle is open and closed, the circle is opened and closed as the same; the constant circle is provided with a groove and the roller is embedded into the groove and rolls in the groove; a connecting rod passes through the center hole of the roller, the roller is in rotation circle; two girdling devices for bergamot pear branches are connected together by the connecting rod; a girdling handle is fixed on the connecting rod; one end of the girdling handle is provided with a girdling knife and the other end of the girdling handle is provided with a connecting plate; driven by power, the girdling knife does circular motion to girdle pear branches with the fixed point of the handle and the connecting rod as the center and with a fixed point of handle girdling knife and a connecting rod fixed point as the center and with the distance from the fixed point the tip of the girdling knife as the radius.

Description

technical field [0001] The invention relates to an electric fragrant pear girdling device for manpower-assisted hand-held wrench variable-diameter branch clamping, which belongs to the field of mechanical technology. Background technique [0002] Fragrant pear saplings 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. The old tree with an age of 40-50 years 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. In addition to the girdling of the main trunk, each side branch of the fragrant pear must be girdled every year. The growth angle of each side branch is not only the same, the distance bet...

Problems solved by technology

[0002] Fragrant pear saplings 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. The old tree with an age of 40-50 years 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. In addition to the girdling of the main trunk, each side branch of the fragrant pear must be girdled every year. The growth angle of each side branch is not only the same, the distance between the side branches 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 knife is achieved by the expansion and contraction of the rotating oil cylinder to drive the platform to rotate around the axis of rotation. Only one surface can be rotated and tilted, and multiple surfaces in the space cannot be rotated and tilted at the same time. The scope of use has great limitations, and it is only suitable for the trunk of the fragrant pear. Girdling, in addition, the incision width of the girdling branches of fragrant pears ranges from 0.5 to 1.0 cm, and the incision depth ranges from 0.2 to 0.5 cm. The incision should be even, and the phloem contains more woody fibers. During girdling, there is no clamping mechanism, and the phloem adjacent to the girdling will be torn, resulting in too large girdling area, and the girdling of fragrant pears is not easy to heal, and nutrient transportation is blocked, affecting the growth and fruit setting rate of fragrant pears
