Manual assistance hand-held ratchet strip ratchet pawl variable-diameter branch clamping electric girdling device for longans

Abstract

The invention provides an manual assistance hand-held ratchet strip ratchet pawl variable-diameter branch clamping electric girdling device for longans. The manual assistance hand-held ratchet strip ratchet pawl variable-diameter branch clamping electric girdling device for the longans comprises a handle, a spring, a rotating shaft, a movable circle, a setting circle, a ratchet strip and a ratchet pawl. The spring is fixedly installed on the handle and is a tension spring, during the operation, the ratchet strip and the ratchet pawl are engaged to fix the movable circle on branches of the longans to prevent the movable circle from rotating with a girdling 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 into a whole circle, when the handle is opened and closed, the setting circle is opened and closed in a follow-up mode, a groove is formed in the setting circle, a roller is embedded in the groove and rolls in the groove, a link rod runs through a center hole of the roller, the roller rotates in circles, the link rod connects two longan tree girdling devices, a girdling handle is fixed on the link rod, one end of the girdling handle is provided with the girdling knife, and the other end is provided with a link plate. Under the manual assistance, the girdling knife make a circular motion to girdle the longans, with the fixing point of the handle and the link rod as the center of the circle and the distance between the fixing point and the knife point of the girdling knife as the radius.

Description

technical field [0001] The invention relates to a manually assisted hand-held longan girdling device with ratchet pawls and variable diameter branches, which belongs to the field of mechanical technology. Background technique [0002] 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. The treatment technology of spiral girdling on the trunk or main branch is 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 number of open female flowers can be increased, and the pollination period can be extended. Improve 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 ...

Problems solved by technology

[0002] 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. The treatment technology of spiral girdling on the trunk or main branch is 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 number of open female flowers can be increased, and the pollination period can be extended. Improve 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. In addition to the main trunk girdling of longan, each side branch must be girdled every year. Branches also need to be girdled, the growth angle of each side branch is not only the same, the distance between 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. The inclination angle of the girdling knife is determined by the rotation The telescoping of the oil cylinder drives the platform to rotate around the rotating shaft. It can only realize the rotation and tilt of one surface, and cannot realize the simultaneous rotation and tilt of multiple surfaces in the space. The scope of use has great limitations. It is only suitable for the trunk girdling of longan. The incision width range of girdling branches is 1.0-3.0 cm, the incision depth range is 0.2-0.8 cm, the incision should be even, the phloem contains more wood fibers, and the girdling knife does not have a clamping mechanism when girdling the girdling. , the phloem adjacent to the girdling is torn, resulting in too large girdling area, the girdling of longan is not easy to heal, and the nutrient transport is blocked, which affects the growth and fruit setting rate of longan
