Pomelo tree girdling device capable of human-assistance hand-held gear-rack reducing branch clamping

Abstract

The invention provides a pomelo tree girdling device capable of human-assistance hand-held gear-rack reducing branch clamping. The device comprises a handle, a spring, a rotation shaft, a moving circle, a fixed circle, a gear, a rack, a servo motor and a micro direct current motor, wherein the spring is firmly installed on the handle; the server motor drives rotation of the gear; the gear is meshed with the rack; the rack moves so as to drive the moving circle to be fixed on a branch of a pomelo tree; the handle is divided into two parts; the fixed circle is installed on the handle; two parts of the fixed circle are buckled into a whole circle; when the handle is opened or closed, the fixed circle will also be opened and closed under driving; a groove is formed in the fixed circle; a roller is embedded into the groove and rolls in the groove; a linkage rod passes through a center hole of the roller; the roller is rotated circumferentially; two pomelo tree girdling devices are connected by the linkage rod; a girdling handle is fixed on the linkage rod; a girdling cutter is disposed on one end of the girdling handle, and a linkage plate is disposed on the other end; and under manual assistance, the girdling cutter makes circular motion with a fixation point of the handle and the linkage rod as the circle center and with the distance from the fixation point to the girdling cutter tip as the radius so as to conduct girdling of the pomelo tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held rack and pinion variable-diameter branch clamping pomelo girdler, which belongs to the field of mechanical technology. Background technique [0002] The pomelo tree needs to be girdled twice in one growing season. The first time should be in the middle and early May. It mainly inhibits the growth of spring shoots, forms moderate branches, lays the foundation for flower bud differentiation, and at the same time has the effect of preserving fruit for the first-hanging fruit trees. The second time is in early August, it can reduce the hair loss of autumn shoots and control late autumn shoots, and promote the physiological differentiation of flower buds. For flourishing trees with unbalanced vegetative growth and reproductive growth, hormone imbalance in the tree will lead to difficulties in flower bud differentiation and fruit stabilization. After peeling, the channel of the phloem screen tube is cut ...

[0002] The pomelo tree needs to be girdled twice in one growing season. The first time should be in the middle and early May. It mainly inhibits the growth of spring shoots, forms moderate branches, lays the foundation for flower bud differentiation, and at the same time has the effect of preserving fruit for the first-hanging fruit trees. The second time is in early August, it can reduce the hair loss of autumn shoots and control late autumn shoots, and promote the physiological differentiation of flower buds. For flourishing trees with unbalanced vegetative growth and reproductive growth, hormone imbalance in the tree will lead to difficulties in flower bud differentiation and fruit stabilization. After peeling, the channel of the phloem screen tube is cut off, causing the transportation of carbohydrates to the root system to be blocked, inhibiting root growth and nutrient absorption, thereby playing a role in controlling water, and the accumulation of nutrients in the upper part of the girdling mouth improves the growth rate of the tree body. The concentration of cell fluid and the ratio of carbon to nitrogen can promote the differentiation of flower buds and increase the fruit setting rate. In addition to the main trunk girdling of pomelo trees, 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, but the side branches The distance between them 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 girdling knife is realized by rotating the platform around the shaft through the expansion and contraction of the rotating oil cylinder, and only one surface can be rotated. Tilting can not realize the simultaneous rotation and tilting of multiple surfaces in the space, and the scope of use has great limitations. It is only suitable for the girdling of the trunk of the pomelo tree. In addition, the incision width of the girdling branches of the pomelo tree ranges from 1.0 to 3.0 cm. The incision depth ranges from 0.2 to 0.5 cm, and the incision should be even. The phloem contains more wood fibers. When the girdling knife is girdling the girdling, there is no clamping mechanism, which will tear the phloem adjacent to the girdling, resulting in If the peeling area is too large, the girdling of the pomelo tree is not easy to heal, and the transportation of nutrients is blocked, which affects the growth and fruit setting rate of the pomelo tree
