Manpower-assisted handheld triangle-block pomelo tree girdling device for clamping branches with different diameters

Abstract

The invention provides a manpower-assisted handheld triangle-block pomelo tree girdling device for clamping a branch with variable diameters. The device comprises hand grips, a spring, a rotary shaft, triangular clamping blocks and a steady circle. The spring is fixedly arranged on the hand grips and is a tension spring, during the work, the acting force of the spring makes the triangular clamping blocks firmly fixed to a branch of a pomelo tree so as to prevent the branch from rotating along with a girdling knife, the hand grips are divided into two parts, the steady circle installed on the hand grips, the two parts of the steady circle are buckled together to form a whole circle, and the steady circle is opened and closed along with the opening and closing of the hand grips. Grooves are formed in the steady circle, idler wheels are embedded into the grooves and rotate in the grooves, a link bar penetrates through center holes of the idler wheels and the idler wheels do circular movement. Two pomelo tree girdling devices are connected together through the link bar, a girdling handle is fixed to the link bar, one end of the girdling handle is provided with the girdling knife, and the other end of the girdling handle is provided with a link plate. Under the manpower assistance, the girdling knife does circular movement with the fixed point of the hand grips and the link bar as the center and the distance from the fixed point to the point of the girdling knife as the radius so as to conduct girdling on the pomelo tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held triangular block variable-diameter branch clamping pomelo girdling device, 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 tub...

Problems solved by technology

[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
