Artificial auxiliary handheld winter jujube tree girdling machine capable of clamping branch in variable-diameter manner by using ratchet strip and pawl

Abstract

The invention provides an artificial auxiliary handheld winter jujube tree girdling machine capable of clamping a branch in a variable-diameter manner by using a ratchet strip and a pawl. The machine comprises a handle, a spring, a rotation shaft, a movable ting, a fixed ring, the ratchet strip and the pawl, wherein the spring which is a tension spring is fixedly installed on the handle; when in operation, the pawl is engaged with the ratchet strip to fix the movable ring on a branch of a winter jujube tree so as to be prevented from rotating along with a girdling knife; the handle is divided into two parts; the fixed ring is installed on the handle; two parts of the fixed ring are buckled to form a whole ring; the fixed ring is opened and closed along with the opening and closing of the handle; a groove is arranged on the fixed ring; an idler wheel is embedded into the groove and rolls in the same; a link rod penetrates through the center hole of the idler wheel; the idler wheel rotates circumferentially; the two winter jujube tree girdling machines are connected together by the link rod; a girdling handle is fixed on the link rod; the girdling knife is arranged at one end of the girdling handle while a link plate is arranged on the other end; and under artificial auxiliary, the girdling knife rotates circumferentially by taking the fixed point of the handle and the link rod as a circle center and the distance between the fixed point and the knife point of the girdling knife as a radius to girdle the winter jujube tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held ratchet ratchet ratchet 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
