Manual assistance handheld electronic winter jujube ring peeling machine for holding branches with changing diameter

Abstract

The invention provides a manually assisted hand-held electric winter jujube girdler for clamping branches with variable diameters, including a handle, a spring, a rotating shaft, a clamping block, a fixed circle and a micro DC motor, and a spring is fixedly installed on the handle. During operation, the spring The force will fix the clamping block on the branch of Dongzao to prevent it from rotating with the ringing knife. The handle is divided into two parts. The fixed circle is installed on the handle. The two parts of the fixed circle are buckled together to form a complete circle. The handle When it opens and closes, the fixed circle also opens and closes accordingly. There is a groove on the fixed circle, and the roller is embedded in the groove and rolls in the groove. The link passes through the center hole of the roller, and the roller rotates in a circle. Connect two winter jujube girdling devices together, the girdling handle is fixed on the connecting rod, one end of the girdling handle is provided with a girdling knife, and the other end is provided with a connecting plate, driven by power, the girdling knife is connected with the handle and The fixed point of the connecting rod is the center of the circle, and the radius of the knife tip from the fixed point to the girdling knife is used as a circular motion to girdling the winter jujube.

Description

technical field [0001] The invention relates to an artificially assisted hand-held electric winter jujube girdler for clamping branches with variable diameters, 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. Trees over 3 years old, strong and vigorous, with large flower volume are girdled during the blooming stage. In addition to the trunk girdling of winter jujube, each side branch must be girdled every year. The growing branches also need to be girdled. The growth angle of each side branch is not only the same, 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. The inclination angle of the girdling knife It is realized by the expansion and contraction of the rotary oil cylinder to drive ...

[0002] The girdling of winter jujube is an important measure to improve the fruit setting rate. Trees over 3 years old, strong and vigorous, with large flower volume are girdled during the blooming stage. In addition to the trunk girdling of winter jujube, each side branch must be girdled every year. The growing branches also need to be girdled. The growth angle of each side branch is not only the same, 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. The inclination angle of the girdling knife It is realized by the expansion and contraction of the rotary oil cylinder to drive the platform to rotate around the rotating shaft. Only one surface can be rotated and tilted, and multiple surfaces can not be rotated and tilted at the same time. The scope of use has great limitations. It is only suitable for the trunk girdling of winter jujube. In addition, The incision width of the girdling branches of Dongzao is in the range of 0.8-3.0 cm, and the incision depth is in the range of 0.2-0.5 cm. The incision should be even. The phloem contains more wood fibers. The supporting mechanism will tear the phloem adjacent to the girdling, resulting in too large girdling area, and the girdling of Dongzao is not easy to heal, affecting the growth and fruit setting rate of Dongzao
