Description

Technical Field

[0001] This utility model relates to the field of branch and leaf pruning technology, and in particular to a cherry planting branch and leaf pruning device. Background Technology

[0002] Pruning in cherry cultivation is an important management measure that involves purposefully shortening branches and leaves to adjust the tree structure, promote growth and development, and improve fruit quality. Its core purpose is to optimize ventilation and light penetration, balance nutrient distribution, and control tree vigor.

[0003] Existing manual pruning shears are not convenient for adjusting the direction of the shears during pruning, and require a large grip force to drive the shears to cut branches that are hard or thick, resulting in low efficiency.

[0004] An existing patent (publication number: CN218163661U) discloses a fruit tree pruning device. This fruit tree pruning device connects the inner sprocket of the cutter to a spool on one side. Under the action of a spring at one end of the spool, the traction rope wound on the outside of the spool is pulled, triggering the rotation of the inner sprocket of the cutter, so that the chainsaw can quickly prune the branches and leaves of the fruit tree, improving the efficiency of fruit tree branch and leaf pruning. At the same time, an eccentric cam on one side of the cutter is fixedly connected to another sprocket. The rotation of the eccentric cam drives the piston rod in the oil reservoir to move repeatedly, automatically spraying the lubricating oil in the oil reservoir onto the surface of the chainsaw through an atomizing nozzle, lubricating the chainsaw and helping to reduce the wear of the chainsaw.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, some existing cherry tree pruning devices require manual handling, which is particularly problematic when pruning and managing large-scale cherry tree plantings. This results in significant labor costs and low pruning efficiency.

[0006] Therefore, a cherry tree branch and leaf pruning device is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A cherry planting branch and leaf pruning device includes a base plate 1, an adjusting cylinder 2 is provided on the top of the base plate 1, a transmission mechanism 9 is provided on the top of the adjusting cylinder 2, a pruning mechanism 8 is provided on the left side of the transmission mechanism 9, and there are two pruning mechanisms 8. Universal wheels 10 are rotatably connected to the four corners of the bottom of the base plate 1.

[0030] The trimming mechanism 8 includes two trimmers 801, two sockets 802, a rotating post 803, and two screws 804. The two sockets 802 are respectively opened at the top and bottom of the rotating post 803. The trimmers 801 are movably inserted into the sockets 802. The screws 804 pass through the rotating post 803 on the side near the rotating post 803 and extend into the interior of the trimmers 801. The surface of the screws 804 is connected to the internal threads of the rotating post 803.

[0031] In this embodiment: By holding the push handle 7 to push the base plate 1, the casters 10 can flexibly turn for easy movement. The speed of the variable frequency motor 904 is adjusted by the external controller, and the pruning shears 801 are driven by the belt 903 to rotate at high speed. During the push, the branches and leaves of neatly planted cherry seedlings can be pruned in batches. The top can then be pruned with an external electric pruning tool, which improves efficiency and reduces manpower. When the pruning shears 801 are worn, they can be replaced by unscrewing the screw 804. When the pruning shears 801 are not in use, the protective cover 3 can be inserted into the connecting frame 11 by holding the handle 19 to limit the position and cover the pruning shears 801 to prevent accidental injury. When adjusting the pruning height, the telescopic plate 13 is pulled up and down to adjust the height. After aligning with the limiting hole 15, the insert block 16 is inserted and magnetically attracted to the adjusting cylinder 2 to limit the height. The transparent acrylic protective plate 5 on the top of the base plate 1 is supported by the support rod 6 to block flying branches and leaves and ensure safety. The variable frequency motor 904 is fixed by the bracket 14 to ensure stability.

[0032] Specifically, such as Figure 2 and Figure 6 As shown, a fixing plate 12 is provided on the right side of the rotating column 803, a protective cover 3 is provided on the left side of the fixing plate 12, a connecting frame 18 is fixedly connected to the top of the protective cover 3, and a connecting frame 11 is fixedly connected to the top of the right side of the fixing plate 12. The connecting frame 18 is movably inserted into the inside of the connecting frame 11.

[0033] Specifically, such as Figure 6 As shown, a handle 19 is fixedly connected to the top of the protective cover 3, and the protective cover 3 is made of lightweight plastic.

[0034] In this embodiment: the protective cover 3 is connected to the connecting frame 11 on the fixing plate 12 via the connecting bracket 18. It can be quickly installed when not in use, completely covering and protecting the trimmer 801 to prevent accidental injury. The protective cover 3 is made of lightweight plastic material, which makes it easy for operators to move the protective cover 3 by holding the handle 19. This reduces the weight of the protective cover 3 while ensuring ease of use and safety.

[0035] Specifically, such as Figure 4 As shown, the transmission mechanism 9 includes two driven wheels 901, two rotating shafts 902, two belts 903, a variable frequency motor 904, and a driving wheel 905. The right side of the driven wheel 901 is fixedly connected to the output shaft of the variable frequency motor 904. The rotating shaft 902 is rotatably connected inside the fixed plate 12. The left side of the driven wheel 901 is fixedly connected to the right side of the rotating shaft 902. The belt 903 is movably sleeved between the surfaces of the driving wheel 905 and the driven wheel 901. The right side of the rotating column 803 is fixedly connected to the left side of the rotating shaft 902.

[0036] Specifically, such as Figure 4 As shown, brackets 14 are fixedly connected to both the front and rear sides of the variable frequency motor 904, and the left side of the bracket 14 is fixedly connected to the right side of the fixing plate 12.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, a fixing frame 4 is fixedly connected to the right side of the fixing plate 12, and a telescopic plate 13 is fixedly connected to the bottom of the fixing frame 4. The bottom of the telescopic plate 13 extends into the interior of the adjusting cylinder 2 and is in movable contact with the interior of the adjusting cylinder 2. A limiting hole 15 is opened on the right side of the telescopic plate 13. The number of limiting holes 15 is several and they are evenly distributed on the right side of the telescopic plate 13. An insert block 16 is provided on the right side of the adjusting cylinder 2. The left side of the insert block 16 passes through the adjusting cylinder 2 and extends into the interior of the limiting hole 15. A magnetic block 17 is fixedly connected to the surface of the insert block 16. The surface of the magnetic block 17 is magnetically attracted to the surface of the adjusting cylinder 2.

[0038] In this embodiment: In the transmission mechanism 9, the variable frequency motor 904 is controlled to rotate by an external controller. The output shaft of the variable frequency motor 904 drives the drive wheel 905 to rotate, which in turn drives the driven wheel 901, the rotating shaft 902 and the rotating column 803 to work together via the belt 903, so as to realize the flexible adjustment of the speed of the pruning shears 801 to adapt to different pruning needs. The variable frequency motor 904 is firmly installed on the right side of the fixed plate 12 by the bracket 14 to ensure stable operation. In the height adjustment structure, the telescopic plate 13 cooperates with the adjusting cylinder 2, and is positioned by inserting the plug 16 into the limiting hole 15. The plug 16 is magnetically attracted to the adjusting cylinder 2 by the magnetic block 17 to prevent the plug 16 from slipping. The pruning height can be precisely adjusted to suit cherry seedlings of different heights.

[0039] Specifically, such as Figure 1 As shown, a transparent acrylic protective plate 5 is provided on the top of the base plate 1. Support rods 6 are fixedly connected to both the front and rear sides of the transparent acrylic protective plate 5. The bottom of the support rods 6 is fixedly connected to the top of the base plate 1.

[0040] Specifically, such as Figure 1 As shown, a push handle 7 is fixedly connected to the front side of the top of the base plate 1.

[0041] In this embodiment: the transparent acrylic protective plate 5 on the base plate 1 is supported by the support rod 6, which effectively blocks the flying branches and leaves during the pruning process and protects the safety of the operators. The push handle 7 is set on the front side of the base plate 1, which makes it easy to push the base plate 1. Together with the casters 10, the base plate 1 can move flexibly, which significantly improves the convenience and efficiency of cherry seedling pruning operations.

[0042] Working principle: By holding the push handle 7 to push the base plate 1, the casters 10 at the bottom of the base plate 1 can rotate flexibly, facilitating the movement of the base plate 1 in the cherry seedling planting area. The speed of the variable frequency motor 904 is adjusted by the external controller. The variable frequency motor 904 drives the drive wheel 905 to rotate, which is transmitted through the belt 903, causing the driven wheel 901 and the rotating shaft 902 to rotate synchronously. This drives the rotating column 803 and the pruning shears 801 connected to the rotating shaft 902 to rotate at high speed. During the movement of the base plate 1, the rotating pruning shears 801 can perform batch pruning of the branches and leaves of the neatly planted cherry seedlings. Afterwards, only the top of the cherry seedlings needs to be pruned using an external electric pruning tool, which greatly improves the efficiency of cherry seedling pruning and reduces manpower input. When the pruning shears 801 are worn, the screw 804 can be unscrewed to remove the old blade from the insertion hole 802 of the rotating column 803 and replace it with a new pruning shears 801. When not in use, the protective cover 3 can be removed by holding the handle 19. By inserting the connecting bracket 18 into the connecting frame 11, the protective cover 3 can be positioned on the left side of the fixed plate 12 to cover the pruning shears 801, preventing accidental injury from the pruning shears 801. When the pruning height needs to be adjusted, pull the telescopic plate 13 up or down. After the limiting hole 15 on the telescopic plate 13 is aligned with the appropriate position on the adjusting cylinder 2, insert the insert block 16 into the limiting hole 15. The magnetic block 17 is attracted and fixed to the adjusting cylinder 2 to prevent the insert block 16 from falling out, thus achieving flexible adjustment of the pruning height. In addition, the transparent acrylic protective plate 5 on the top of the base plate 1 can block the flying branches and leaves during pruning, ensuring the safety of the operator. The protective plate is stably supported by the support rod 6. The variable frequency motor 904 is fixed to the fixed plate 12 through the bracket 14 to ensure stable operation. This solves the problem that some existing cherry planting branch and leaf pruning devices need to be moved by hand, especially when pruning and managing cherry seedlings on a large scale, which requires a lot of labor and has low pruning efficiency.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
