Manual power-assisted hand-held push-and-pull electromagnet variable diameter branch clamping persimmon tree girdling device

Abstract

The invention provides a manual power-assisted hand-held push-and-pull electromagnet variable diameter branch clamping persimmon tree girdling device comprising a handle, a spring, a rotating shaft, a moving circle, a fixed circle, and push-and-pull electromagnets. The spring is fixedly installed on the handle, and the spring is an extension spring. When the girdling device works, the moving circle is fixed on a branch of a persimmon tree by springs disposed on the push-and-pull electromagnets to be prevented from rotating with a girdling knife. The handle is divided into two portions, the fixed circle is installed on the handle, two portions of the fixed circle are buckled to be a full circle, and the fixed circle is driven to open and close along with opening and closing of the handle. The fixed circle is provided with a groove, rollers are embedded into the groove and roll in the groove, a link rod passes through central holes of the rollers, and the rollers perform circular motion. Two persimmon tree girdling devices are connected by the link rod, a girdling handle is fixed on the link rod, one end of the girdling handle is provided with a girdling knife, and the other end of the girdling handle is provided with a link plate. Under the manual power assistance, the girdling knife performs circular motion, by using the fixed point of the handle and the link rod as the center of circle and using the distance from the fixed point to the point of the girdling knife as the radius, so as to perform girdling on the persimmon tree.

Description

technical field [0001] The invention relates to a manually assisted hand-held push-pull electromagnet variable-diameter branch clamping persimmon tree girdling device, 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, the...

[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
