Artificial supplementary handheld electric pomelo tree girdling device with gear and rack reducing branch clamping function

Abstract

The invention provides an artificial supplementary handheld electric pomelo tree girdling device with the gear and rack reducing branch clamping function. The girdling device comprises a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a gear, a rack, a servo motor and a miniature direct-current motor. The spring is fixedly installed on the handle, the servo motor drives the gear to rotate, the gear is meshed with the rack, and the rack moves and then drives the moving circle to be fixed to a pomelo tree branch; the handle is divided into two parts, the fixed circle is installed on the handle, the two parts of the fixed circle are fastened to form a whole circle, when the handle is opened or closed, the fixed circle is opened and closed followingly, a groove is formed in the fixed circle, an idler wheel is embedded into the groove and rolls in the groove, a link bar penetrates through a center hole of the idler wheel, the idler wheel does circumferential rotation, two pomelo tree girdling devices are connected together through the link bar, a girdling handle is fixed to the link bar, a girdling cutter is arranged at one end of the girdling handle, a link plate is arranged at the other end of the girdling handle, and the girdling cutter does circular motion with the handle and link bar fixing point as the circle center and the distance from the fixing point to the cutter point as the radius to girdle pomelo trees.

Description

technical field [0001] The invention relates to an electric pomelo girdling device for manually assisting a hand-held pinion rack variable-diameter branch clamping, belonging 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 sc...

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
