Artificial auxiliary handheld electric persimmon tree girdling device for clamping variable-diameter branch

Abstract

The invention provides an artificial auxiliary handheld electric persimmon tree girdling device for clamping a variable-diameter branch. The artificial auxiliary handheld electric persimmon tree girdling device for clamping the variable-diameter branch comprises a handle, a spring, a rotation shaft, a clamping block, a fixed circle and a minitype direct current motor. The handle is fixedly provided with the spring. In the operation process, the clamping block is fixed on the branch of the persimmon tree by the acting force of the spring, and is prevented to be rotated along with a girdling blade. The handle is divided to two parts. The fixed circle is installed on the handle. Two parts of the fixed circle are closed to form a whole circle. The fixed circle is opened and closed along with the open and close of the handle. The fixed circle is provided with a groove. A roller is embedded in the groove and is rolled in the groove. A linkage rod passes through the central hole of the roller. The roller is rotated around the circumference. Two persimmon tree girdling devices are connected by the linkage rod. A girdling handle is fixed on the linkage rod. One end of the girdling handle is provided with the girdling blade, and the other end is provided with a linkage plate. Under the drive of the power, the girdling blade is circumferentially moved by using the fixed point of the handle and the linkage rod as the center, and using the distance from the fixed point to the point of the girdling blade as the radius, for girdling the persimmon tree.

Description

Technical field [0001] The invention relates to an artificially assisted hand-held electric persimmon tree girdling device used for holding variable-diameter branches, which belongs to the field of mechanical technology. Background technique [0002] Persimmon girdling can effectively control vegetative growth, promote the formation of flower buds, make young trees bear early fruit, and improve early economic benefits. Persimmon girdling can inhibit the growth of branches, prevent nutrient outflow, fruit setting rate, and single branch fruit setting. The number is greatly increased, the fruit weight is increased, and the root growth is not affected. The 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 initial flowering to the full flowering stage. The widening of the ring peeling inhibits reproductive growth and improves The fruit setting rate, widening the ring peeling mouth mu...

Problems solved by technology

[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 0.5 cm. The incision should be even, and the phloem contains more woody fibers. When peeling and girdling, there is no clamping mechanism, and the phloem adjacent to the girdling will be torn, resulting in too large girdling area, and the girdling of the persimmon tree is not easy to heal, affecting the growth and fruit setting rate of the persimmon tree
