Human-assisted and handheld type electric litchi girdling device provided with coil spring and buckle and capable of realizing diameter-variable clamping of branches

Abstract

The invention provides a manual assisted hand-held electric litchi girdler with coil spring buckle variable-diameter branches clamping, including a handle, a spring, a rotating shaft, a moving circle, a fixed circle and a micro DC motor, and a spring is fixedly installed on the handle, and the moving circle is made of Composed of a coil spring and a coil spring box, the circular through hole and buckle set on the coil spring fix the moving circle on the lychee branch, the handle is divided into two parts, the fixed circle is installed on the handle, and the two parts of the fixed circle are fastened together Together they form a full circle, the handle opens and closes, and the fixed circle also opens and closes accordingly. There is a groove on the fixed circle, the roller is embedded in the groove and rolls in the groove, and the link runs through the center hole of the roller , the roller rotates in a circle, the connecting rod connects the two litchi girders 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. The girdling knife takes the fixed point of the handle and the connecting rod as the center of the circle, and takes the fixed point to the tip of the girdling knife as the radius to perform circular motion to girdling the litchi.

Description

technical field [0001] The invention relates to an electric lychee girdler for manually assisting a hand-held coil spring buckle with variable diameter branches to clamp, and belongs to the field of mechanical technology. Background technique [0002] Litchi girdling is an important measure to inhibit the growth of branch shoots, prevent the outflow of nutrients, and increase the fruit setting rate, fruit shape index and fruit weight. 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, 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 is large in size and easy to rotate. The radius is large, and the inclination angle of the girdling knife is realized by the rotating oil cylinder telescopically driving the platform to rotate around the shaft. O...

[0002] Litchi girdling is an important measure to inhibit the growth of branch shoots, prevent the outflow of nutrients, and increase the fruit setting rate, fruit shape index and fruit weight. 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, 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 is large in size and easy to rotate. The radius is large, and the inclination angle of the girdling knife is realized by the rotating oil cylinder telescopically driving the platform to rotate around the 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 and is only suitable for For the girdling of the main trunk of litchi, in addition, the incision width range of girdling branches of litchi is between 1.0-3.0 cm, the incision depth range is between 0.2-0.8 cm, the incision should be even, and the phloem contains more woody fibers. When the girdling knife is girdling at the girdling place, there is no clamping mechanism, which will tear the phloem near the girdling place, resulting in excessive girdling area, difficult healing of the girdling place of litchi, blocked nutrient delivery, and affecting the growth and development of litchi.
