Human-assisted and handheld type winter jujube girdling device capable of realizing diameter-variable branch clamping through pushing and pulling electromagnets

Abstract

The invention provides a human-assisted and handheld type winter jujube girdling device capable of realizing diameter-variable branch clamping through pushing and pulling electromagnets. The winter jujube girdling device comprises a handle, a spring, a rotating shaft, a moving circle, a fixed circle and the pushing and pulling electromagnets, wherein the spring is a tension spring and fixedly mounted on the handle, and during operation, the spring arranged on the pulling electromagnet fixes the moving circle on a branch of a winter jujube so as to prevent the moving circle from rotaing 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 buckled to form a whole circle, and the fixed circle is opened and closed with opening and closing of the handle; slots are formed in the fixed circle and rollers are embedded into the slots and roll in the slots; a link rod penetrates through center holes in the rollers, the rollers conduct circular rotation, and the link rod connects two winter jujube girdling devices together; a girdling handle is fixed on the link rod, 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 the girdling cutter conducts circular motion with the fixing point of the handle and the link rod as a circle center and the distance from the fixing point to the cutter tip of the girdling cutter as a radius to girdle the winter jujube under human assistance.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping 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, and it ...

[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
