Human-assisted and handheld type pomelo tree girdling device for diameter-variable branch clamping

Abstract

The invention provides a hand-held pomelo tree girdler for clamping variable-diameter branches, which includes a handle, a spring, a rotating shaft, a clamping block, and a fixed circle. A spring is fixedly installed on the handle, and the spring is a tension spring. At the same time, the force of the spring will firmly fix the clamping block on the pomelo branch to prevent the ringing knife from rotating. The handle is divided into two parts, the fixed circle is installed on the handle, and the two parts of the fixed circle are fastened on the handle. Together they form a full circle, the handle opens and closes, and the fixed circle also opens and closes accordingly. There is a groove on the fixed circle, the roller is embedded in the groove and rolls in the groove, and the link passes through the center hole of the roller. The roller rotates in a circle in the groove, the connecting rod connects the two pomelo girders together, the girdling handle is fixed on the connecting rod, one end of the girdling handle is provided with a girdling knife, and the other end is provided with a connecting plate, Under the artificial assistance, the girdling knife takes the fixed point of the handle and the connecting rod as the center of the circle, and takes the fixed point to the tip of the girdling knife as the radius to make a circular motion to girdling the pomelo tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held pomelo girdler for clamping branches with variable diameters, 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 off,...

[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, which affects the growth and fruit setting rate of the pomelo tree
