Manually-assisted handheld ratchet-pawl variable-diameter branch clamping persimmon girdling device

Abstract

The present invention provides a manually assisted hand-held ratchet ratchet ratchet variable diameter branch clamping persimmon tree girdler, including a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a ratchet strip and a ratchet, and a spring is fixedly installed on the handle. The spring is a tension spring. During operation, the pawl and the ratchet mesh to fix the moving circle on the branch of the persimmon tree, so as not to rotate with the girdling knife. The handle is divided into two parts, the fixed circle is installed on the handle, and the two fixed circles The parts are buckled together to 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 roller The center hole of the center hole, the roller rotates in a circle, the connecting rod connects the two persimmon tree 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, Under the manual assistance, 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 make a circular motion to gird the persimmon tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held ratchet ratchet ratchet variable-diameter branch clamping device for persimmon tree girdling, which belongs to the field of mechanical technology. Background technique [0002] Persimmon tree girdling can effectively control vegetative growth, promote flower bud formation, make young trees bear fruit early, and improve early economic benefits. Persimmon tree girdling can inhibit the growth of branches and prevent the outflow of nutrients. The average number is greatly improved, the fruit weight is increased, and the root growth is not affected. Girdling can significantly inhibit the growth of the auxiliary shoots of the persimmon tree. The girdling of the persimmon tree is carried out from the early flowering stage to the full flowering stage. It 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,...

[0002] Persimmon tree girdling can effectively control vegetative growth, promote flower bud formation, make young trees bear fruit early, and improve early economic benefits. Persimmon tree girdling can inhibit the growth of branches and prevent the outflow of nutrients. The average number is greatly improved, the fruit weight is increased, and the root growth is not affected. Girdling can significantly inhibit the growth of the auxiliary shoots of the persimmon tree. The girdling of the persimmon tree is carried out from the early flowering stage to the full flowering stage. It 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 larger in size and larger in radius of gyration , the inclination angle of the girdling knife is realized by the rotation of the rotating oil cylinder to drive the platform to rotate around the axis of rotation. It can only realize the rotation and inclination of one surface, and cannot realize the simultaneous rotation and inclination of multiple surfaces in the space. The scope of use has great limitations and is only suitable for persimmons. The main trunk of the tree is girdled. In addition, the incision width of the girdling branches of the persimmon tree ranges from 2.0 to 4.0 cm, and the incision depth ranges from 0.2 to 0.8 cm. The incision should be even, and the phloem contains more woody fibers. When girdling the girdling, there is no clamping mechanism, and the phloem adjacent to the girdling is torn, resulting in too large girdling area, the girdling of the persimmon tree is not easy to heal, and the nutrient transport is blocked, which affects the growth and fruit setting of the persimmon tree Rate
