Description

Technical Field

[0001] The utility model belongs to the technical field of seedling pruning, and in particular relates to a seedling pruning and shaping device. Background Art

[0002] With the development of urban greening, gardening, and agriculture, the care and management of fruit trees and seedlings has become a crucial component in maintaining urban beauty and ecological balance. As trees grow, they naturally develop numerous side branches around the main trunk. These branches not only affect the tree's overall shape but can also cause insufficient light, hinder air circulation, and ultimately affect its health. Therefore, regular pruning and shaping are crucial to maintaining healthy tree growth.

[0003] Currently, pruning is primarily performed in two ways: manual pruning and mechanical pruning. While manual pruning allows for more precise control of pruning location and degree, it is inefficient and labor-intensive, especially when dealing with tall trees, posing significant safety risks. On the other hand, with technological advancements, mechanical pruning equipment is gradually being used in practical operations. However, existing mechanical pruning equipment has some significant drawbacks, such as:

[0004] Mechanical pruning lacks the flexibility to adjust cutting angles like manual labor, making it easy to accidentally damage the trunk or important branches, leading to tree damage. After pruning, the broken ends of branches are exposed, making them susceptible to pathogens and stimulating the germination of new buds. This not only increases the workload for follow-up care but can also worsen the tree's health. Traditional mechanical pruning equipment lacks the ability to immediately treat post-pruning wounds. Different tree species have significantly different characteristics, such as branch hardness and thickness. Existing mechanical pruning equipment is often only suitable for trees of specific types or sizes, limiting its scope of application. Utility Model Content

[0037] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the seedling pruning and shaping device of the present invention in conjunction with the accompanying drawings.

[0038] like Figures 1-9As shown, a seedling pruning and shaping device of the present invention includes a pushing disk 100, and the pushing disk 100 increases its own contact friction by a rubber ring 110 sleeved on its outer surface; a connecting main shaft 120 is connected through the middle of the pushing disk 100, wherein the connecting main shaft 120 and the pushing disk 100 are rotatably connected, and the end portion of the surface of the connecting main shaft 120 is sleeved with a multi-axis movable support arm 130, and the other end of the multi-axis movable support arm 130 can be suspended and mounted on the head of a small agricultural tractor. The pruning and shaping device is moved as a whole by the small agricultural tractor. The multi-axis movable support arm 130 can adjust the overall position of the rubber ring 110, and a torsion spring is installed on the surface of the connecting main shaft 120, one end of the torsion spring is connected to the pushing disk 100, so when the rubber ring 110 is rotated under force, the torsion spring is stretched and stored. When the rubber ring 110 is not affected by external force, the pushing disk 100 is driven to reset by the torsion spring.

[0039] Two ring sleeves 220 are staggered on the surface of the main shaft 120 and located above the pushing disk 100, and one end of the ring sleeve 220 is connected to the fixed arm 200, wherein the two ring sleeves 220 are staggered up and down on the surface of the main shaft 120, and a hydraulic rod 210 is movably installed on one side of the fixed arm 200 through a rotating shaft, wherein the other end of the hydraulic rod 210 is movably installed on the surface of the pushing disk 100 through a rotating shaft, and the position of the fixed arm 200 can be adjusted by the hydraulic rod 210, thereby changing the angle of the pruning assembly 300;

[0040] The pruning assemblies 300 are symmetrically arranged at the front and rear ends of the right side of the pushing disc 100 for pruning branches. The pruning assembly 300 includes a pruning knife 330 for pruning branches. In order to drive the pruning knife 330, a pruning drive 310 is installed above the pruning knife 330. The output end of the pruning drive 310 is fastened to the middle part of the surface of the pruning knife 330 by a bolt.

[0041] To fix the pruning drive 310, a support tube 320 is fastened to the bottom of the pruning drive 310 by bolts. A turntable 600 is sleeved on the upper part of the surface of the support tube 320. The surface of the turntable 600 is provided with a plurality of arc grooves 601. The arc grooves 601 cooperate with the push-connecting shaft 550. The inner surface of the turntable 600 is connected to a slip ring 602, and the surface of the support tube 320 is provided with a slide groove 321. The slide groove 321 cooperates with the slip ring 602, so that the slip ring 602 can be slidably sleeved on the inner cavity of the slide groove 321, so that the turntable 600 is movably mounted on the surface of the support tube 320.

[0042] A limit slide plate 700 is provided below the rotary disc 600 and below the adjustable anti-scratch assembly 500. A linear sliding groove 701 is provided at the end of the limit slide plate 700 for use with the arcuate groove 601. A mounting groove 702 is provided on the inner ring of the end of the limit slide plate 700. The mounting groove 702 is used to assemble the crown main gear 520.

[0043] Specifically, a blocking plate 710 is connected to the bottom of the limiting sliding plate 700 via a support plate. The blocking plate 710 is used to cover the spray assembly 400 located below the limiting sliding plate 700 to prevent branches from entangled with the surface pipe of the spray assembly 400. The limiting sliding plate 700 is fixedly sleeved on the bottom of the support tube 320.

[0044] An adjustable anti-slice assembly 500 is provided below the surface of the pruning assembly 300. The adjustable anti-slice assembly 500 is used to prevent the pruning blades 330 from damaging the tree trunk when cutting, and can also drive the two sets of pruning assemblies 300 to adjust their own positions. The adjustable anti-slice assembly 500 includes a drive motor 510 as a power source and a crown-shaped main gear 520. The drive motor 510 is fastened to the inner wall of the support tube 320 by bolts, and the crown-shaped main gear 520 is installed in the inner cavity of the mounting groove 702. The mounting groove 702 is rotatably provided on the bottom surface of the inner cavity of the mounting groove 702. The surface of the crown-shaped main gear 520 is meshed with a plurality of auxiliary gears 521.

[0045] The adjustable anti-slicing assembly 500 also includes a limiting component 530 and a sliding support component 540, wherein the limiting component 530 and the sliding support component 540 are adjacently arranged, and both the limiting component 530 and the sliding support component 540 are multiple and arranged in a ring around the end of the limiting sliding disk 700, and the limiting component 530 is composed of a limiting screw rod 531 and a limiting wire drum 532, wherein the input shaft of the limiting screw rod 531 is connected to the surface of the auxiliary gear 521, and the outer surface of the limiting screw rod 531 is threadedly connected to the inner surface of the limiting wire drum 532, in order to prevent the limiting wire drum 532 from revolving with the limiting screw rod 531, a limiting drum 1 is sleeved on the surface of the limiting wire drum 532, and the bottom of the limiting drum 1 makes linear sliding contact with the end of the limiting sliding disk 700;

[0046] The sliding support component 540 is composed of a sliding rod 541 and a sliding cylinder 542. The sliding cylinder 542 is slidably mounted on the outer surface of the sliding rod 541. To increase the stability of the sliding cylinder 542, a second limiting cylinder is mounted on the surface of the sliding cylinder 542. The bottom of the second limiting cylinder is in linear sliding contact with the end of the limiting sliding plate 700.

[0047] In order to fix the limiting screw rod 531 and the sliding rod 541, one end of the limiting screw rod 531 and the sliding rod 541 is slidably mounted with a fixing frame through a bearing, and the bottom of the fixing frame is fastened to the bottom of the limiting sliding plate 700 by bolts;

[0048] The surfaces of the limiting wire drum 532 and the slide cylinder 542 are both installed with a mounting bracket 560, wherein one end of the surface of the mounting bracket 560 is penetrated by a pushing shaft rod 550, and the end of the pushing shaft rod 550 extends to the inner cavity of the adjacent arc-shaped groove 601, and the bottom of the pushing shaft rod 550 extends to the inner cavity of the straight-moving slide groove 701. The surface of the pushing shaft rod 550 is in sliding contact with the connection between the arc-shaped groove 601 and the straight-moving slide groove 701 respectively, and the straight-moving slide groove 701 is used to linearly limit the pushing shaft rod 550, and then when it moves, the arc-shaped groove 601 can be dialed to push the other pushing shaft rods 550 to move. The other end of the mounting bracket 560 is rotatably installed with a pulley portion 570, wherein the pulley portion 570 is located on the outer side of the top of the pruning knife 330;

[0049] Therefore, the distance between the pulley portion 570 and the pruning blade 330 can be dynamically adjusted according to the main branch and the branches at the edge. When in use, the pruning blade 330 can cut the branches growing out of the edge of the main branch, while being limited by the pulley portion 570, the pruning blade 330 can be prevented from cutting into the main branch.

[0050] Specifically, the output end of the driving motor 510 passes through the support tube 320 and is connected to the shaft end of the limiting screw rod 531 of the adjacent auxiliary gear 521; therefore, when the driving motor 510 rotates, it can drive the auxiliary gear 521 to rotate through the adjacent limiting screw rod 531, and then drive the crown main gear 520 to rotate. The rotation of the crown main gear 520 can also drive the other multiple auxiliary gears 521 to rotate, thereby ultimately driving the multiple limiting screw rods 531 to rotate. 531 is threadedly connected to the limiting wire drum 532, so that the limiting wire rod 531 rotates to drive the limiting wire drum 532 to pull the adjacent mounting bracket 560 to move. When the mounting bracket 560 moves, the pushing shaft 550 is affected by the arc groove 601 on the rotating disk 600 and is limited by the linear sliding groove 701, so that the rotating disk 600 rotates, and the pulley part 570 connected to the sliding support component 540 moves synchronously, thereby synchronously adjusting the positions of the multiple pulley parts 570;

[0051] As a further optimization of this solution, in this solution, the auxiliary gear 521 and the limiting component 530 can be provided in 1-5 groups, without having to provide more. At the same time, when the limiting component 530 is reduced, the number of the sliding support components 540 needs to be increased. In this way, the limiting component 530 can not only cooperate with the adjustment of the position of the pulley portion 570, but also limit and self-lock it.

[0052] At the same time, a spraying assembly 400 for spraying medicine to prevent pests and diseases is installed below the adjustable anti-slicing assembly 500. The spraying assembly 400 includes a main pipe 410 and an atomizing nozzle 430 for atomizing the medicine. The main pipe 410 passes through the inner cavity of the support tube 320, and the input end of the main pipe 410 is connected to the output end of an external medicine delivery pump through a flange. In this way, the medicine in the external medicine box can be delivered to the main pipe 410 through the medicine delivery pump for subsequent spraying through the atomizing nozzle 430; the atomizing nozzle 430 is arranged at an angle.

[0053] The output end of the main pipeline 410 is connected to an annular pipe 420, which is installed in a groove cavity opened at the bottom of the limiting sliding plate 700. The outside of the annular pipe 420 is connected to multiple connecting pipes 421, wherein the connecting pipe 421 is composed of two fixed pipes and a telescopic hose. There are two fixed pipes and one telescopic hose. The two ends of the telescopic hose are connected to the opposite sides of the two fixed pipes, and the opposite sides of the two fixed pipes are respectively connected to the opposite ends of the annular pipe 420 and the atomizing nozzle 430.

[0054] Specifically, the bottom end of the push-connect shaft 550 passes through the bottom of the limiting sliding plate 700, and the connecting pipe 421 passes through the push-connect shaft 550 and is connected to the atomizing nozzle 430, wherein the fixed pipe in the connecting pipe 421 is connected to the push-connect shaft 550;

[0055] In addition, a control valve body, such as a solenoid valve, is installed on the surface of the main pipeline 410 to control the delivery of the liquid medicine;

[0056] The adjustable anti-scratch component 500 and the spray component 400 are used in conjunction with each other. When the pulley part 570 on the adjustable anti-scratch component 500 is adjusted by force, it can drive the pushing shaft 550 to pull the connecting pipe 421 to drive the atomizing nozzle 430 to move, thereby changing the position of the atomizing nozzle 430.

[0057] The working principle of a seedling pruning and shaping device: Finally, when removing the branches growing on the edge of the main trunk, the pruning and shaping device is driven by the small agricultural tractor to move as a whole, and the position of the pulley part 570 is adjusted in advance. The pulley part 570 is driven by the driving force of the driving motor 510, and under the action of the driving motor 510, when it is forced to move, it can synchronously drive the atomizing nozzle 430 to move, change the spraying position of the liquid medicine, and after dynamic adjustment, the pruning knife 330 is driven to work through the support tube 320. The two pruning knives 330 revolve around the main trunk root and prune the main trunk. It only takes a few seconds to clear the small branches around the roots of a main trunk and trim the small branches on the edge of the roots. When trimming branches, the two pruning knives 330 are used in conjunction with the push disk 100, and a plurality of pulley parts 570 are installed above the two pruning knives 330. The push disk 100 mainly plays a fixing role. After the driver finds a good angle, he controls the two pruning knives 330 to surround the main trunk, and the pulley part 570 is close to the main trunk, which can prevent the pruning knives 330 from damaging the surface of the main trunk when cutting small branches, and can cooperate with the push disk 100 to help rotate;

[0058] When the two pruning blades 330 are rotated to pass through the main trunk, first, the rubber ring 110 on the pushing disk 100 in a moving state will be close to one side of the main trunk, and the friction between the pushing disk 100 and the main trunk will drive the pushing disk 100 to rotate. When the pushing disk 100 rotates, the two pruning blades 330 can be driven to deviate 180 degrees and then pass through the current branch; thereby, multiple small branches around the main trunk are pruned and removed; in this way, the small branches growing next to the roots of multiple main trunks are pruned and removed reciprocally.

[0059] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
