Manually assisted hand-held push-pull electromagnet variable diameter branch clamping electric longan ring peeling tool

Abstract

The invention provides a manually assisted hand-held push-pull electromagnet variable diameter branch clamping longan ring peeling tool. The ring peeling tool comprises a handle, a spring, a rotating shaft, a moving circle, a setting circle and push-pull electromagnets; the spring which is a tension spring is fixedly installed on the handle, during operation, springs arranged on the push-pull electromagnets fix the moving circle to a branch of longan so as to prevent rotation along with a ring peeling knife, the handle is divided into two parts, the setting circle is installed on the handle, two parts of the setting circle are buckled together to form a full circle, the handle is opened and closed, and the setting circle is opened and closed accordingly; a groove is formed in the setting circle, a rolling wheel is embedded into the groove and rolls in the groove, a link rod penetrates through a center hole of the rolling wheel, the rolling wheel rotates in a circle, the link rod connects two longan ring peeling tools together, a ring peeling handle is fixed to the link rod, the ring peeling knife is arranged at one end of the ring peeling handle, a link plate is arranged at the other end of the ring peeling handle, and under manual assistance, the ring peeling knife moves in a circle by taking the fixed point of the handle and the link rod as the circle center and taking the distance from the fixed point to a knifepoint of the ring peeling knife as the radius to conduct ring peeling on the longan.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping longan girdler, 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. Provide more sufficient nutrients for the flower bud differentiation and flowering of the fruiting mother branch. Longan has obvious large and small years, or even empty every year. By adopting girdling technology, it can overcome the large and small years.

[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. Provide more sufficient nutrients for the flower bud differentiation and flowering of the fruiting mother branch. Longan has obvious large and small years, or even empty every year. By adopting girdling technology, it can overcome the large and small years. Longan has obvious large and small years, even every year If there is no fruit, the girdling technology can overcome the large and small annual results and obtain high yields year after year. The longan girdling control tip to promote flower and fruit setting technology is to perform spiral girdling on the trunk or main branch after the last autumn shoot of longan matures. Treatment technology 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, the flower quality is good, but also the batches of female flowers open, the pollination period is prolonged, and the fruit setting rate is increased. In addition, girdling can also Delay the flowering period, avoid low temperature, rainy and cold damage in early spring, which is conducive to pollination during the flowering period and reduce young fruit abortion. In addition to the main trunk girdling of longan, each side branch must be girdled every year, and the branches growing on the side branches must also be girdled. The growth of each side branch The angles are 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 has a large volume and a large radius of gyration. It can realize the rotation and tilt of one surface, but cannot realize the simultaneous rotation and tilt of multiple surfaces in space. The scope of use is very limited. It is only suitable for the girdling of longan trunks. In addition, the incision width of longan girdling branches ranges from 1.0 to 3.0 cm, the incision depth ranges from 0.2 to 0.5 cm, the incision should be even, and the phloem contains more wood fibers. When the girdling knife is girdling the girdling, there is no clamping mechanism, and the phloem near the girdling is torn , resulting in too large girdling area, the girdling of longan is not easy to heal, and nutrient transport is blocked, which affects the growth and fruit setting rate of longan
