Artificial supplementary handheld electric litchi nut girdling device with push-pull electromagnet reducing branch clamping function

Abstract

The invention provides an artificial supplementary handheld electric litchi nut girdling device with the push-pull electromagnet reducing branch clamping function. The girdling device comprises a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a push-pull electromagnet and a miniature direct-current motor. The spring is fixedly installed on the handle, and a spring arranged on the push-pull electromagnet fixes the moving circle to a litchi nut branch so that the moving circle can be prevented from rotating along with a girdling cutter; the handle is divided into two parts, the fixed circle is installed on the handle, the two parts of the fixed circle are fastened to form a whole circle, when the handle is opened or closed, the fixed circle is opened and closed followingly, a groove is formed in the fixed circle, an idler wheel is embedded into the groove and rolls in the groove, a link bar penetrates through a center hole of the idler wheel, the idler wheel does circumferential rotation, two litchi nut girdling devices are connected together through the link bar, a girdling handle is fixed to the link bar, the girdling cutter is arranged at one end of the girdling handle, a link plate is arranged at the other end of the girdling handle, and under artificial supplement, the girdling cutter does circular motion with the handle and link bar fixing point as the circle center and the distance from the fixing point to the cutter point as the radius to girdle litchi nuts.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping electric litchi girdler, which belongs to the field of mechanical technology. Background technique [0002] Spiral girdling can not only effectively promote the differentiation of flower buds and preserve flowers and fruits, but also reduce the severe fruit cracking caused by heavy rains during the fruit expansion period, which causes the skin to absorb water less than the pulp. , Preserve flowers and fruits, reduce the serious fruit cracking caused by heavy rains in the period of fruit expansion, prevent the outflow of nutrients, improve the fruit setting rate, fruit shape index and fruit weight, and do not affect the root system Growth, the girdling of litchi is carried out before flowering or in full bloom. In addition to the trunk girdling of litchi, each side branch must be girdled every year, and the branches growing on the side branch...

Problems solved by technology

[0002] Spiral girdling can not only effectively promote the differentiation of flower buds and preserve flowers and fruits, but also reduce the severe fruit cracking caused by heavy rains during the fruit expansion period, which causes the skin to absorb water less than the pulp. , Preserve flowers and fruits, reduce the serious fruit cracking caused by heavy rains in the period of fruit expansion, prevent the outflow of nutrients, improve the fruit setting rate, fruit shape index and fruit weight, and do not affect the root system Growth, the girdling of litchi is carried out before flowering or in full bloom. In addition to the trunk girdling of litchi, 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, but also The spacing 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 realized by rotating the platform around the rotating shaft through the expansion and contraction of the rotating oil cylinder. Only one surface can be rotated and tilted, and it cannot Realize the simultaneous rotation and tilt of multiple surfaces in the space, and the scope of use has great limitations. It is only suitable for the girdling of the trunk of the litchi. In addition, the incision width of the girdling branches of the litchi ranges from 1.0 to 2.0 cm, and the incision depth ranges from 0.2 ~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, which will tear the phloem adjacent to the girdling, resulting in an excessively large girdling area. The girdling of litchi is not easy to heal, and the nutrient transport is blocked, which affects the growth and fruit setting rate of litchi
