Description

Technical Field

[0001] This utility model belongs to the field of fruit tree cultivation, and in particular relates to a rotatable angle-adjustable pruning support for European plum trees. Background Technology

[0002] Prunus cerasifera, a perennial deciduous shrub belonging to the genus Prunus in the family Rosaceae, possesses high nutritional value and economic potential. Its fruit is rich in nutrients such as calcium, iron, and vitamin C, and its cultivation has rapidly developed in the specialty fruit tree industry in recent years. However, without proper tree shaping management, Prunus cerasifera is prone to developing a tree structure characterized by overlapping branches, dense canopy, and poor ventilation and light penetration. This not only affects photosynthetic efficiency and fruit quality but also increases susceptibility to pests and diseases, making later management more difficult. Therefore, tree shaping is one of the key management measures in Prunus cerasifera cultivation.

[0003] Currently, in production practice, it is common to use ropes to fix the branches of European plum to wire mesh or crossbars erected in the air in order to achieve traction and load-bearing support for the branches. However, after the branches are fixed by ropes, the spatial position and growth angle of the branches are forcibly locked. When harvesting the fruit, it is difficult for fruit farmers to approach the branches from the best angle. They need to walk around the tree frequently, change their standing position and climbing angle repeatedly. This is not only inconvenient to operate, but also very easy to cause missed harvesting and damage to branches and leaves.

[0004] Therefore, there is a particular need for a rotatable pruning support for Prunus armeniaca trees to solve the above problems. Summary of the Invention

[0005] To overcome the disadvantages of fixed branches in European plum trees, which lead to inconvenient harvesting, low efficiency, and easy omissions and damage to branches and leaves, this utility model provides a rotating angle-adjustable pruning support for European plum trees.

[0006] This utility model is achieved through the following technical means: a rotatable angle-adjustable pruning support for Prunus armeniaca trees, comprising a support plate, a planting pot, guide rails, sliders, threaded sleeves, threaded rods, support rods, a rotating plate, hooks, and an adjusting rod. The planting pot is rotatably mounted inside the support plate. Multiple guide rails arranged in a circular array are fixed to the upper part of the planting pot. A slider is slidably mounted inside each guide rail. A threaded sleeve is fixed to the top of each slider. A threaded rod is threaded inside each threaded sleeve. A support rod is fixed to one end of each threaded rod. A rotating plate is rotatably mounted to one end of each support rod. Each rotating plate has multiple equidistant openings along its length. The device includes distributed mounting holes, with hooks installed in two mounting holes on each rotating plate. An adjusting rod is rotatably mounted inside each guide rail, passing through and threadedly engaging with the corresponding slider. It also includes a spur gear, a gear ring, pedals, and a return spring. The spur gear is fixed to the lower outer periphery of the planting pot. The gear ring is slidably mounted inside the support plate, encircling and meshing with the spur gear. Multiple evenly distributed pedals are fixed to the outer periphery of the gear ring. The lower part of the support plate has multiple grooves, the same number as the number of pedals. The pedals extend into their corresponding grooves and slide against the support plate through these grooves. The two ends of the return spring are fixed to the gear ring and the support plate, respectively.

[0007] Furthermore, the gear ring matches the tooth profile of the spur gear, and the axial thickness is equal.

[0008] Furthermore, the pedal contacts the top of the support plate groove, and the distance between the bottom surface of the pedal and the bottom of the groove is greater than the axial thickness of the gear ring.

[0009] Furthermore, an anti-slip pad is provided on the top surface of the pedal.

[0010] Furthermore, the return spring is a high-strength compression spring.

[0011] Furthermore, a knob is provided at the end of the adjusting rod furthest from the planting pot.

[0012] Beneficial effects: By setting up a rotary locking mechanism consisting of a spur gear, a gear ring, a pedal, and a return spring, the angle of the planting pot can be flexibly adjusted and stably positioned, allowing fruit farmers to conveniently harvest fruit branches in different directions from a fixed working position, avoiding frequent walking around the tree, significantly reducing labor intensity, and improving harvesting convenience and work efficiency.

[0020] Example: A rotatable angle-adjustable pruning support for Prunus armeniaca trees, such as... Figures 1-6As shown, the device includes a support plate 1, a planting pot 2, guide rails 7, sliders 8, threaded sleeves 9, threaded rods 10, support rods 11, a rotating plate 12, hooks 14, and adjusting rods 15. The planting pot 2 is rotatably positioned in the center of the support plate 1. Four guide rails 7 arranged in a circular array are fixedly connected to the upper part of the planting pot 2. A slider 8 is slidably mounted inside each guide rail 7. A threaded sleeve 9 is fixedly connected to the top of each slider 8. A threaded rod 10 is threaded inside each threaded sleeve 9. A support rod 11 is fixedly connected to the upper end of each threaded rod 10. 1. Each support rod 11 has a rotating plate 12 rotatably mounted on its upper end. Each rotating plate 12 has multiple mounting holes 13 evenly distributed along its length. Hooks 14 are fixed to two mounting holes 13 on each rotating plate 12 by bolts. Each guide rail 7 has an adjusting rod 15 rotatably mounted inside. The adjusting rod 15 passes through the corresponding slider 8 and is threaded to it. Rotating the adjusting rod 15 can drive the slider 8 to move radially along the guide rail 7. The end of the adjusting rod 15 away from the planting pot 2 has a knob. It also includes a spur gear 3 and a gear ring 4. The pedal 5 and return spring 6, and the spur gear 3 are fixedly connected to the lower outer peripheral wall of the planting pot 2. The gear ring 4 is slidably disposed inside the support plate 1, encircling and meshing with the spur gear 3. Through the meshing relationship between the gear ring 4 and the spur gear 3, the planting pot 2 is fixed on the support plate 1, preventing the planting pot 2 from rotating arbitrarily. The gear ring 4 and the spur gear 3 have matching tooth profiles and equal axial thickness, ensuring stable meshing and uniform force distribution. Four evenly distributed pedals 5 are fixedly connected to the outer periphery of the gear ring 4. The top surface of the pedal 5 is provided with an anti-slip pad to support the plant. The lower part of the disc 1 has four sliding grooves, the same number as the pedal 5. The pedal 5 extends into the corresponding sliding groove and forms a sliding engagement with the support disc 1 through the sliding groove. The pedal 5 contacts the top of the sliding groove of the support disc 1, and the distance between the bottom surface of the pedal 5 and the bottom of the sliding groove is greater than the axial thickness of the gear ring 4, ensuring that the gear ring 4 can completely disengage from the spur gear 3 when the pedal 5 is pressed. The upper and lower ends of the return spring 6 are fixedly connected to the gear ring 4 and the support disc 1 respectively, and can provide a reset force for the gear ring 4. The return spring 6 is a high-strength compression spring to ensure reliable reset.

[0021] When using it, the fruit grower first places the support plate 1 firmly in the predetermined position of the cultivation site, and then plants the European plum seedling in the planting pot 2. As the plant grows, it is necessary to prune the tree and support the branches. During the growth of branches, fruit growers can make dynamic adjustments according to the distribution direction and spatial position of the branches: First, manually rotate the adjusting rod 15 clockwise to drive the slider 8 to slide inward along the guide rail 7, thereby driving the threaded sleeve 9 and the rotating plate 12 above it to move closer to the center of the plant, so that the hook 14 gradually approaches the target branch. Then, rotate the threaded rod 10 clockwise to make it rise inside the threaded sleeve 9, adjust the height of the support rod 11, so that the rotating plate 12 reaches a suitable vertical position for traction of the branch. Then, adjust the angle of the rotating plate 12, align the two hooks 14 with the branch to be supported, tie one end of the flexible binding rope to the branch, and hang the other end on the hook 14 to achieve traction positioning and load-bearing support for the branch. By repeating the above operations, the rotating plate 12 and hook 14 in other directions can be adjusted in turn to adapt to the growth trend of branches in different directions, forming a three-dimensional, multi-angle support system for the European plum tree. When the fruit harvesting stage begins, the farmer steps down on any of the pedals 5. Through the linkage, the gear ring 4 overcomes the elasticity of the return spring 6 and moves downward along the support plate 1 until it is completely disengaged from the spur gear 3. At this point, the rotational freedom of the planting pot 2 is released. Then, the farmer manually rotates the planting pot 2 to smoothly turn the branches with dense fruit or located on the back side to the front, making it easy to pick them at close range without obstruction. Before picking, the farmer releases the pedal 5, the return spring 6 returns to its original state, pushes the gear ring 4 upward to reset, and re-engages with the spur gear 3, locking the angle of the planting pot 2 again. This prevents the plant from rotating unexpectedly due to external force or wind during the harvesting process, ensuring operational stability. By repeating the above operations, the entire plant's fruit can be harvested efficiently from a fixed position.
