Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco plant topping, in particular to a telescopic tobacco plant topping device. Background Art
[0002] Topping the tobacco plant can remove the apical dominance of tobacco plant growth, prompting the tobacco plant to shift from reproductive growth to nutritional growth, which is beneficial to the development and material accumulation of leaves, especially the middle and upper leaves. At the same time, it will stimulate the transfer of nutrients to the root system and promote the development of the root system. After a period of time after topping, a large amount of nicotine will be synthesized in the root system and then transferred to the leaves, improving the quality of tobacco leaves.
[0003] At present, the main tools for topping tobacco plants are scissors, pruning shears and knives.
[0004] When using the above-mentioned tool for topping operation, it is difficult for topping operators who are not tall to perform topping operation on some tall varieties or tall and strong tobacco plants. At the same time, the removed top branches are easy to damage the effective leaves of the tobacco plants during the falling process, which will cause certain losses. Therefore, a retractable tobacco plant topping device is proposed. Utility Model Content

[0007] Furthermore, the auxiliary moving component includes two travel grooves with an inclined design, and the travel grooves are symmetrically opened at the top of the movable plate and penetrate to the bottom. Round rods are slidably provided in the two travel grooves, and both ends of the two round rods are commonly fixedly connected with movable blocks, and the movable blocks are fixedly connected to adjacent scissor blades. When the movable plate moves, the two scissor blades can be pushed closer to or away from each other.
[0008] Furthermore, one side of the outer surfaces of the two movable blocks is slidably connected to a slide rail, and the slide rail is fixedly connected to the shell. The slide rail has a limiting effect on the movable block, which can ensure the stability of the movement of the movable block.
[0009] Furthermore, the push-pull assembly includes two springs, and the springs are fixedly mounted on an inner wall of one side of the shell, and the springs are fixedly connected to the movable plate. The springs can assist the movable plate in resetting by using their own elastic force.
[0010] Furthermore, the push-pull assembly also includes a square rod, and the square rod is fixedly connected to the movable plate. The square rod passes through the inner wall of the shell and extends to the interior of the movable rod and is slidably connected thereto. The square rod is fixedly connected to the screw rod. The square rod design is adopted, and when the movable rod and the shell rotate, the square rod can be driven to rotate accordingly.
[0011] Furthermore, a fixed handle is fixedly connected to one end of the main cylinder, and the fixed handle matches the movable handle, and the fixed handle can assist the movable handle in moving.
[0012] Furthermore, the two scissor blades are staggered to facilitate the topping operation on the tobacco plants.
[0013] Beneficial effects of the utility model:
[0014] When the utility model is in use, the retractable tobacco plant topping device adopts a retractable design as a whole through the arranged movable rod, movable plate, auxiliary moving component, scissor blade, push-pull component, screw rod, spline shaft, movable handle and tobacco plant claw, which is convenient for topping varieties with taller plant types or tobacco plants with taller and stronger growth, and reduces the difficulty of topping. At the end of use, the overall length can be shortened for easy storage. At the same time, during the topping process, the top residual branches can be fixed to prevent them from falling and damaging the effective leaves of the tobacco plants.
