Artificially-assisted handheld wrench variable-diameter branch clamping bergamot pear girdling device

Abstract

The invention provides an artificially-assisted handheld wrench variable-diameter branch clamping bergamot pear girdling device which comprises a handle, a spring, a rotary shaft, a wrench and a fixed circle. The spring is fixedly installed on the handle and is a tension spring. During operation, an acting force of the spring makes the wrench firmly fixed to a bergamot pear branch so as to prevent rotation with a girdling knife, the handle is divided into two parts, the fixed circle is installed on the handle, the two parts of the fixed circle are buckled together to form a whole circle, the fixed circle is also opened and closed in a following mode when the handle is opened and closed, a groove is formed in the fixed circle, a roller is embedded into the groove and rolls in the groove, a connecting rod penetrates through a central hole of the roller, the roller performs circular motion, the connecting rod makes two bergamot pear girdling devices connected together, a girdling handle is fixed to the connecting rod, the girdling knife is arranged at one end of the girdling handle, a connecting plate is arranged at the other end of the girdling handle, the girdling knife uses a fixing point for the handle and the connecting rod as the center of a circle under artificial assistance and the distance from the fixing point to a point of the girdling knife is regarded as the radius to perform circular motion so as to perform bergamot pear girdling.

Description

technical field [0001] The invention relates to a manual-assisted hand-held wrench with variable diameter branch clamping pear stripper, which belongs to the field of mechanical technology. Background technique [0002] Fragrant pears have obvious large and small years, and even do not bear fruit every year. By adopting girdling technology, it can overcome the large and small years of fruiting and obtain high yields year after year. Finally, the treatment technology of spiral girdling is carried out on the trunk or main branch 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, prolonging During the pollination period, the fruit setting rate can be improved. In addition, girdling can delay the flowering period, avoid low temperature, rainy and cold damage in early spring, facil...

Problems solved by technology

[0002] Fragrant pears have obvious large and small years, and even do not bear fruit every year. By adopting girdling technology, it can overcome the large and small years of fruiting and obtain high yields year after year. Finally, the treatment technology of spiral girdling is carried out on the trunk or main branch 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, prolonging During the pollination period, the fruit setting rate can be improved. In addition, girdling can 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 For girdling, 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 driven by the expansion and contraction of the rotary cylinder. The platform can be rotated around the rotation axis, 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 is very limited, and it is only suitable for the trunk girdling of fragrant pears. The incision width range for peeling branches is 1.0-3.0 meters, and the incision depth range is 0.2-0.5 cm. The incision should be even, and the phloem contains more wood fibers. The phloem near the girdling is torn, resulting in too large girdling area, the girdling of fragrant pears is not easy to heal, and nutrient delivery is blocked, which affects the growth and fruit setting rate of fragrant pears
