Human assistance handheld type spring plate diameter-variable branch clamping electric winter jujube girdling device

Abstract

The invention provides a human assistance handheld type spring plate diameter-variable branch clamping electric winter jujube girdling device. The device comprises a handle, a spring, a rotary shaft, a spring plate, a setting circle and a mini-type direct-current motor, wherein the spring is fixedly mounted on the handle and the spring is a tension spring; in a working process, the spring plate is clamped on a branch of winter jujubes, so that a girdling cutter is prevented from rotating; the handle is divided into two parts; the setting circle is mounted on the handle; two parts of the setting circle are buckled together to form a whole circle; when the handle is opened and closed, the setting circle and the spring plate can also be opened and closed; the setting circle is provided with a groove; a rolling wheel is embedded into the groove and rolls in the groove; a linking rod penetrates through a central hole of the rolling wheel and the rolling wheel does circumference rotation; the linking rod is used for connecting two winter jujube girdling devices; a girdling handle is fixed on the linking rod; the girdling cutter is arranged at one end of the girdling handle and a linking plate is arranged at the other end of the girdling handle; and under the human assistance, the girdling cutter takes the handle and a linking rod fixed point as the circle center and takes a distance from the fixed point to a cutter point of the girdling cutter as a radius to do circular movement, so as to carry out girdling on the winter jujubes.

Description

technical field [0001] The invention relates to a manually assisted hand-held electric winter jujube girdling device for clamping branches with variable diameter spring plates, 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 ver...

[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
