Manpower-assisted handheld push-pull electromagnet variable-diameter branch-clamping pomelo tree ring peeling device

Abstract

The invention provides a manpower-assisted handheld push-pull electromagnet variable-diameter branch-clamping pomelo tree ring peeling device, comprising a handle, a spring, a rotating shaft, a movable ring, a fixed ring and push-pull electromagnets, wherein the spring is a tension spring and is fixedly arranged on the handle; during operation, the spring arranged on the push-pull electromagnets fixes the movable ring on a pomelo tree branch to prevent the movable ring from rotating with a ring peeling knife; the handle is divided into two parts; the fixed ring is arranged on the handle, and two parts of the fixed ring are buckled together to form a whole ring; when the handle is opened and closed, the fixed ring is opened and closed with the handle; the fixed ring is provided with a groove; a roller wheel is inlaid in the groove and rolls in the groove; a link rod penetrates through a center hole of the roller wheel; the roller wheel performs circular movement; the link rod connects two pomelo tree ring peeling devices together; a ring peeling handle is fixed on the link rod, one end of the ring peeling handle is provided with a ring peeling knife, and the other end is provided with a link plate; and under manpower assistance, the ring peeling knife takes a fixed point between the handle and the link rod as the center of a circle and a distance from the fixed point to the point of the ring peeling knife as a radius to perform circular movement so as to perform ring peeling on pomelo trees.

Description

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

[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
