Manually assisted hand-held longan ring peeling tool for variable diameter branch clamping

Abstract

The invention provides a manual-assisted hand-held longan girdler for clamping branches with variable diameters, which includes a handle, a spring, a rotating shaft, a clamping block, and a fixed circle. A spring is fixedly installed on the handle. , the force of the spring firmly fixes the clamping block on the longan branch to prevent it from rotating with the girdling knife. The handle is divided into two parts, the fixed circle is installed on the handle, and the two parts of the fixed circle are buckled together to form a 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, and the roller is embedded in the groove and rolls in the groove. The link passes through the center hole of the roller, and the roller is in the The circular rotation is made in the groove, and the connecting rod connects the two longan girdling devices together. Next, 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 gird the longan.

Description

technical field [0001] The invention relates to a manually assisted hand-held longan girdler for clamping branches with variable diameters, 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 small annual results, and obt...

Problems solved by technology

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 small annual results, and obtain high yields year after year. Longan girdling control shoots to promote flowering and fruit setting technology is After the last autumn shoot of longan matures, the treatment technology of spiral girdling is performed on the trunk or main branch to promote the differentiation of flower buds, thereby increasing 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 open female flowers, 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 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 5.0 cm, and the incision depth ranges from 0.2 to 0.8 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, and the girdling of longan is not easy to heal, which affects the growth and fruit setting rate of longan
