Artificial supplementary handheld electric persimmon tree girdling device with gear and rack reducing branch clamping function

Abstract

The invention provides an artificial supplementary handheld electric persimmon tree girdling device with the gear and rack reducing branch clamping function. The girdling device comprises a handle, a spring, a rotating shaft, a moving circle, a fixed circle, a gear, a rack, a servo motor and a miniature direct-current motor. The spring is fixedly installed on the handle, the servo motor drives the gear to rotate, the gear is meshed with the rack, and the rack moves and then drives the moving circle to be fixed to a persimmon tree branch; the handle is divided into two parts, the fixed circle is installed on the handle, the two parts of the fixed circle are fastened to form a whole circle, when the handle is opened or closed, the fixed circle is opened and closed followingly, a groove is formed in the fixed circle, an idler wheel is embedded into the groove and rolls in the groove, a link bar penetrates through a center hole of the idler wheel, the idler wheel does circumferential rotation, two persimmon tree girdling devices are connected together through the link bar, a girdling handle is fixed to the link bar, a girdling cutter is arranged at one end of the girdling handle, a link plate is arranged at the other end of the girdling handle, and the girdling cutter does circular motion with the handle and link bar fixing point as the circle center and the distance from the fixing point to the cutter point as the radius to girdle persimmon trees.

Description

technical field [0001] The invention relates to an electric persimmon tree girdling device for manually assisting a hand-held pinion rack variable-diameter branch clamping, belonging 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 number average 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 persimmon trees. The girdling of persimmon trees is carried out from the early flowering stage to the full flowering stage. Fruit setting rate, widening the girdling mouth must be matched with the agronomic techniques of increasing the amount of fertilization and multiple topping. The gird...

[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 number average 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 persimmon trees. The girdling of persimmon trees is carried out from the early flowering stage to the full flowering stage. Fruit setting rate, widening the girdling mouth must be matched with the agronomic techniques of increasing the amount of fertilization and multiple topping. The girdling mouth should be wrapped with plastic film immediately after girdling. It must be girdled, and the branches growing on the side branches must also be girdled. The growth angles of each side branch are 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 has a large volume and a large radius of gyration. The inclination angle of the girdling knife is realized by the expansion and contraction 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 persimmon trees. In addition, the incision width of the girdling branches of persimmon trees ranges from 1.0 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 peeling and girdling, there is no clamping mechanism, which will tear the phloem adjacent to the girdling, resulting in too large girdling area, difficult to heal the girdling of the persimmon tree, hindered nutrient delivery, and affecting the growth and fruit setting rate of the persimmon tree
