Manpower-assisted handheld ratchet-and-pawl variable-diameter branch-clamping electric winter jujube ring peeling device

Abstract

The invention provides a manpower-assisted handheld ratchet-and-pawl variable-diameter branch-clamping electric winter jujube ring peeling device, comprising a handle, a spring, a rotating shaft, a movable ring, a fixed ring, a ratchet, a pawl and a direct-current micromotor, wherein the spring is a tension spring and is fixedly arranged on the handle; the pawl and the ratchet are meshed to fix the movable ring on a winter jujube branch to prevent the movable ring from rotating with a ring peeling knife; the handle is divided into two parts; the fixed ring is arranged on the handle, and two parts of the fixed ring are buckled together to form a whole ring; when the handle is opened and closed, the fixed ring is opened and closed with the handle; the fixed ring is provided with a groove; a roller wheel is inlaid in the groove and rolls in the groove; a link rod penetrates through a center hole of the roller wheel; the roller wheel performs circular movement; the link rod connects two winter jujube ring peeling devices together; a ring peeling handle is fixed on the link rod, one end of the ring peeling handle is provided with a ring peeling knife, and the other end is provided with a link plate; and under driving of power, the ring peeling knife takes a fixed point between the handle and the link rod as the center of a circle and a distance from the fixed point to the point of the ring peeling knife as a radius to perform circular movement so as to perform ring peeling on winter jujubes.

Description

technical field [0001] The invention relates to a manually assisted hand-held electric winter jujube girdling device for clamping and reducing branches with ratchets and pawls, belonging 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 li...
