Electric longan girdling device capable of human-assistance hand-held push-pull electromagnet reducing branch clamping

Abstract

The invention provides an electric longan girdling device capable of human-assistance hand-held push-pull electromagnet reducing branch clamping. The device comprises a handle, a spring, a rotation shaft, a moving circle, a fixed circle, a push-pull electromagnet and a micro direct current motor, wherein the spring is firmly installed on the handle; the spring disposed on the electromagnet fixes the moving circle on a branch of an longan so as to prevent the moving circle from rotating with a girdling cutter; the handle is divided into two parts; the fixed circle is installed on the handle; two parts of the fixed circle are buckled together to form 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 conducts circumferential rotation; two longan girdling devices are connected by the linkage rod; a girdling handle is fixed on the linkage rod; the girdling cutter is disposed on one end of the girdling handle, and a linkage plate is disposed on the other end; and under human 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 between the fixation point and the girdling cutter tip as the radius, so as to conduct girdling of the longan.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping electric longan girdling device, which belongs to the field of mechanical technology. Background technique [0002] The basic principle of spiral girdling of longan branches and girdling to control winter shoots is to reduce the transport of photosynthetic products from the aboveground part of the plant to the roots, inhibit root growth, slow down vegetative growth and winter shoot extraction, and increase the accumulation of carbohydrates in shoots. To provide more sufficient nutrients for the flower bud differentiation and flowering of the fruiting mother branch, longan has obvious size years, even empty every year. By adopting the girdling technology, it can overcome the large and small annual results. Longan has obvious large and small years, or even no fruit every year. By adopting the girdling technology, it can overcome the large and ...

Problems solved by technology

By adopting the girdling technology, it can overcome the large and small annual results. Longan has obvious small and large years, or even no fruit every year. By adopting the girdling technology, it can overcome the large and small annual results, and obtain high yields year after year. Longan girdling control shoots to promote flowering and fruit setting technology After the last autumn shoot of longan matures, the trunk or main branch is spirally girdled to promote the differentiation of flower buds, so as to increase the flowering rate of the next year. After girdling, not only the ratio of female flowers is high, but the flower quality is also good. It can increase the number of female flowers to open, prolong the pollination period, and increase the fruit setting rate. In addition, girdling can also delay the flowering period, avoid low temperature, rainy and cold damage in early spring, facilitate pollination during the flowering period, and reduce young fruit abortion. 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, the distance between the side branches is small, and the radius of gyration is small. Invention patent 201410485285.2 uses a motor driven by a gasoline engine, which is large in size and easy to rotate. The radius is large, and the inclination angle of the girdling knife is realized by the rotating oil cylinder telescopically driving the platform to rotate around the rotating shaft. Only one surface can be rotated and tilted, and multiple surfaces can not be rotated and tilted at the same time. The scope of use has great limitations and is only suitable for For the girdling of the main trunk of longan, in addition, the incision width of longan girdling branches ranges from 1.0 to 2.0 cm, and the incision depth ranges from 0.2 to 0.5 cm. The incision should be even, and the phloem contains more woody fibers. When girdling the girdling, there is no clamping mechanism, and the phloem adjacent to the girdling is torn, resulting in too large girdling area, the girdling of longan is not easy to heal, and nutrient transportation is blocked, which affects the growth and fruit setting rate of longan
