Human-assisted handheld type electric longan girdling device using triangular blocks to clamp branches in variable-diameter manner

Abstract

The invention provides a human-assisted handheld type electric longan girdling device using triangular blocks to clamp branches in a variable-diameter manner. The human-assisted handheld type electric longan girdling device comprises a handle, springs, a rotary shaft, the triangular clamp blocks, a fixed circle and a miniature direct-current motor, wherein one spring is fixedly mounted on the handle, the triangular clamping blocks are firmly fixed on longan branches by the acting force of the springs so as to prevent the girdling device from rotating along with a girdling cutter, the handle is divided into two parts, the fixed circle is mounted on the handle, two parts of the fixed circle are fastened to form a whole circle, the handle opens and closes to allow the fixed circle to open and close, the fixed circle is provided with a groove, rollers are embedded into the groove and roll in the same, a connecting rod penetrates the central holes of the rollers, the rollers rotate circumferentially, two longan girdling device bodies are connected through the connecting rods, a girdling handle is fixed on the connecting rod, one end of the girdling handle is provided with the girdling cutter, the other end of the girdling handle is provided with a connecting plate, and the girdling cutter circularly moves by using the fixing point of the handle and the connecting rod as the circle center and the distance from the fixing point to the tip of the girdling cutter as the radius so as to girdle longan under human assistance.

Description

technical field [0001] The invention relates to a manually assisted hand-held electric longan girdling device for clamping branches with variable diameter triangular blocks, 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 small and large years, and even empty every year. By adopting girdling technology, it can overcome the large and small years. Longan has obvious small and small years, even every year. If there is no fruit, the girdling technology can overcome the large and sm...

[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 small and large years, and even empty every year. By adopting girdling technology, it can overcome the large and small years. Longan has obvious small 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 rate of flower formation in the next year. After girdling, not only the ratio of female flowers is high and the flower quality is good, but also the number of open female flowers can be increased, the pollination period can be extended, and the fruit setting rate can be increased. In addition, girdling can also delay During the flowering period, avoid low temperature, rainy and cold damage in early spring, which is conducive to pollination during the flowering period and reduces 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 angle of each side branch Not only the same, but 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 it cannot realize the simultaneous rotation and tilt of multiple surfaces in space. The scope of use has great limitations, and 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. The girdling area is too large, and the girdling of longan is not easy to heal, which affects the growth and fruit setting rate of longan
