Manual assistance handheld electronic litchi ring peeling machine for holding spring plate branches with changing diameter

Abstract

The invention provides a manually assisted hand-held electric lychee girdler with variable diameter branches clamped by a spring plate, including a handle, a spring, a rotating shaft, a spring plate, a fixed circle and a micro DC motor, and a spring is fixedly installed on the handle, and the spring is an extension spring , during operation, the spring plate is clamped on the lychee branch to prevent it from rotating with the girdling knife. The handle is divided into two parts, and 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 Opening and closing, the fixed circle and the spring plate also open and close 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. , 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 fixed point of the handle and the connecting rod is the center of the circle, and the radius of the fixed point to the tip of the girdling knife is used as a circular motion to girdling the lychees.

Description

technical field [0001] The invention relates to a manually assisted hand-held electric lychee girdler for clamping branches with variable diameter spring plates, which belongs to the field of mechanical technology. Background technique [0002] Litchi spiral girdling is to inhibit the growth of branch shoots, promote the differentiation of flower buds, preserve flowers and fruits, reduce the severe fruit cracking caused by heavy rain during the fruit expansion period, prevent the outflow of nutrients, and improve the fruit setting rate and fruit shape index It does not affect root growth. The girdling of lychee is carried out before flowering or in full bloom. In addition to the girdling of the main trunk, each side branch of lychee 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.

[0002] Litchi spiral girdling is to inhibit the growth of branch shoots, promote the differentiation of flower buds, preserve flowers and fruits, reduce the severe fruit cracking caused by heavy rain during the fruit expansion period, prevent the outflow of nutrients, and improve the fruit setting rate and fruit shape index It does not affect root growth. The girdling of lychee is carried out before flowering or in full bloom. In addition to the girdling of the main trunk, each side branch of lychee 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 adopts 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 is driven by the rotating cylinder. The rotation of the rotating shaft can only realize the rotation and tilt of one surface, and cannot realize the simultaneous rotation and tilt of multiple surfaces in space. The scope of use has great limitations, and it is only suitable for the trunk girdling of litchi. The width ranges from 1.0 to 3.0 cm, and the incision depth ranges from 0.2 to 0.5 cm. The incision should be even, and the phloem contains more wood fibers. The adjacent phloem is torn, resulting in too large girdling area, the girdling of litchi is not easy to heal, and nutrient transport is blocked, which affects the growth and fruit setting rate of litchi
