Human-assistance handheld electrical bergamot pear girding device adopting mode of bar and pawl variable-diameter branch clamping

Abstract

The invention discloses a human-assistance handheld electrical bergamot pear girding device adopting the mode of bar and pawl variable-diameter branch clamping. The device comprises a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a bar, a pawl and a micro-DC motor. The spring is fixedly installed on the handle and is a tension spring. The pawl and a ratch mesh with each other and fix the moving circle on the branch of the bergamot pear to prevent the rotation along with the girding knife. The handle comprises two parts, and the fixed circle is installed on the handle, and the two parts of the fixed circle are fastened together to form a full circle. The fixed circle opens and closes when the handle opens and closes. The fixed circle is provided with a groove, rollers are embedded in the groove and roll in the grooves, and a linking rod passes through a central hole of a roller which moves in a circle. The linking rod connects two bergamot pear girding device bodies together, and a girding handle is fixed on the linking rod, the girding knife is arranged on one end of the girding handle, and the other end is provided with a joining plate. Driven by the power, the girding knife peels the bergamot pear in a girding manner by making circular motion with the fixing point of the handle and the linking rod being the circle center and the distance from the fixing point to the knife point of the girding knife being the radius.

Description

technical field [0001] The invention relates to a manually assisted hand-held electric pear girdling device for holding ratchets and pawls with variable diameter branches, belonging 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. The side branches are girdled at intervals, and each side branch must be girdled every year. , the branches growing on the side branches should also be girdled, the growth angle of eac...

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. The side branches are girdled at intervals, and each side branch must be girdled every year. , the branches growing on the side branches should also be girdled, 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 girdling knife The inclination angle is achieved by the rotating oil cylinder telescopically driving the platform to rotate around the shaft. Only one surface can be rotated and tilted, and multiple surfaces in the space can not be rotated and tilted at the same time. The scope of use has great limitations, and it is only suitable for the backbone ring of Xiangli. In addition, the incision width of the girdling branches of fragrant pears ranges from 1.0 to 3.0 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. When peeling, there is no clamping mechanism, and the phloem adjacent to the girdling is torn, resulting in too large girdling area, the girdling of fragrant pears is not easy to heal, and nutrient transportation is blocked, which affects the growth and fruit setting rate of fragrant pears
