Artificial supplementary handheld electric winter jujube girdling device with push-pull electromagnet reducing branch clamping function

Abstract

The invention provides an artificial supplementary handheld electric winter jujube 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 winter jujube 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 winter jujube 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 winter jujubes.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping electric winter jujube girdler, which belongs to the field of mechanical technology. Background technique [0002] The girdling of winter jujube is an important measure to improve the fruit setting rate. The girdling of winter jujube is carried out in the full flowering stage. In addition to the trunk girdling of winter jujube, each side branch must be girdled every year, and the branches growing on the side branches must also be girdled. Not only are the growth angles 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. , only one surface can be rotated and tilted, and multiple surfaces in space cannot be rotated and tilted at the same time. The scope of use is very limited...

[0002] The girdling of winter jujube is an important measure to improve the fruit setting rate. The girdling of winter jujube is carried out in the full flowering stage. In addition to the trunk girdling of winter jujube, each side branch must be girdled every year, and the branches growing on the side branches must also be girdled. Not only are the growth angles 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. , only one surface can be rotated and tilted, and multiple surfaces in space cannot be rotated and tilted at the same time. The scope of use is very limited, and it is only suitable for the girdling of the main trunk of Dongzao. In addition, the incision width of the girdling branches of Dongzao is within 0.8 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, the girdling of Dongzao is not easy to heal, and the nutrient delivery is blocked, which affects the growth and fruit setting rate of Dongzao
