Artificial auxiliary handheld orange tree girdling machine capable of clamping branch in variable-diameter manner by using gear and rack

Abstract

The invention provides artificial auxiliary handheld orange tree girdling machine capable of clamping a branch in a variable-diameter manner by using a gear and a rack. The machine comprises a handle, a spring, a rotation shaft, a movable ring, a fixed ring, the gear, the rack and a servo motor, wherein the spring is fixedly installed on the handle; the servo motor drives the gear engaged with the rack to rotate, so that the rack moves, and thus the movable ring is driven to be fixed on a branch of an orange tree; the handle is divided into two parts; the fixed ring is installed on the handle; two parts of the fixed ring are buckled to form a whole ring; the fixed ring is opened and closed along with the opening and closing of the handle; a groove is arranged on the fixed ring; an idler wheel is embedded into the groove and rolls in the same; a link rod penetrates through the center hole of the idler wheel; the idler wheel rotates circumferentially; the two orange tree girdling machines are connected together by the link rod; a girdling handle is fixed on the link rod; a girdling knife is arranged at one end of the girdling handle while a link plate is arranged on the other end; and under artificial auxiliary, the girdling knife rotates circumferentially by taking the fixed point of the handle and the link rod as a circle center and the distance between the fixed point and the knife point of the girdling knife as a radius to girdle the orange tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held pinion rack variable diameter branch clamping citrus girdling device, which belongs to the field of mechanical technology.

[0002] Citrus girdling can replace the hormone to protect the fruit, prevent the fruit from being rough, thicken the peel, and weaken the flavor caused by the hormone. It can save the cost of shoot control and overcome the clustering of autumn shoots caused by repeated wiping of summer shoots , the number of weak branches increases, and the quality of the mother branches of autumn shoots decreases, resulting in a vicious cycle of many or no results. Citrus girdling inhibits the growth of spring and summer shoots, and girdling hinders the downward transport of photosynthesis, making citrus The root system of oranges cannot get the supply of nutrients, which inhibits vegetative growth, promotes flower bud differentiation, increases fruit setting rate, promotes fruit expansion, and improves quality. The trunk is girdled, each side branch must be girdled every year, and the branches growing on the side branches must 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. The size is large and the radius of gyration is large. The inclination angle of the girdling knife is realized by the rotating oil cylinder telescopically driving the platform to rotate around the axis of rotation. Only one surface can be rotated and tilted, and multiple surfaces can not be rotated and tilted at the same time. The scope of use is very wide. Limitation, only suitable for citrus trunk girdling, in addition, the incision width range of citrus girdling branches is 0.5-3.0 cm, the incision depth range is 0.2-0.5 cm, the incision should be even, and the phloem contains more When the wood fiber and the girdling knife are girdled at the girdling place, there is no clamping mechanism, which will tear the phloem adjacent to the girdling place, resulting in too large girdling area, the girdling place of citrus is not easy to heal, and the nutrient transport is blocked, which affects Citrus Growth and Fruit Set
