Description

Technical Field

[0001] This utility model belongs to the field of seedling pruning technology, specifically referring to a garden seedling pruning device. Background Technology

[0002] In the daily maintenance of gardens, in order to achieve a good visual effect, it is necessary to adjust the proportion of trees to the environment in a timely manner through shaping and pruning. The traditional pruning method relies on manual hand-held shears, which is inefficient and labor-intensive. Therefore, people have gradually adopted pruning equipment to replace it.

[0003] Existing garden seedling pruning equipment, such as the garden seedling pruning equipment disclosed in application number CN202421346897.9 and the seedling pruning equipment disclosed in application number CN202323615147.5, all adopt a mechanical drive method, and the cutting blades prune the seedlings by changing the height, angle, etc.

[0004] However, in actual use, most gardens have dirt roads, making it inconvenient to move large mechanical equipment. Furthermore, when pruning seedlings at higher elevations, the required equipment is even larger and less flexible in operation. In particular, the cutting angle and direction depend on the equipment's travel path, resulting in fewer applicable occasions and greater limitations in use. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a garden seedling pruning device, which effectively solves the problems of large size and inconvenience of movement of the existing garden seedling pruning devices, while also solving the problems of limited types of seedlings that can be pruned and limited applicable occasions.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a garden seedling pruning device, including a protective cover. Two flywheels are symmetrically arranged inside the protective cover, and a band saw is fitted on the flywheels. A fixed seat is fixed in the middle of the back of the protective cover. A connecting rod is connected to the fixed seat through an angle adjustment mechanism. The end of the connecting rod away from the protective cover is connected to a support rod through a rotating assembly, and two rectangular through holes are symmetrically arranged on the side wall of the support rod. The angle adjustment mechanism includes a fixed shaft and a sleeve. The fixed shaft is fixed to the fixed seat, and the sleeve is rotatably connected to the fixed shaft. The connecting rod is fixed to the side wall of the sleeve and communicates with the inside of the sleeve. The rotating assembly consists of a rotating cylinder and a supporting rotating ring, which are respectively fixed to the ends of the connecting rod and the support rod. At the same time, the supporting rotating ring is rotatably connected to the rotating cylinder.

[0007] As an improvement to this solution, the side wall of the fixed shaft is evenly distributed with several insertion holes along the circumferential direction. The sleeve is internally threaded with a positioning screw. The end of the positioning screw near the fixed shaft is provided with a cylindrical pin, and the pin can be inserted and removed into the insertion hole. At the same time, the side wall of the positioning screw is provided with a circular protrusion with anti-slip grooves on the surface.

[0008] As an improvement to this solution, the bottom of the rotating drum is provided with a through hole, and the support rod, which is fixedly connected to the support ring, passes through the through hole.

[0009] As an improvement to this solution, a base is fixed to one end of the support rod away from the rotating cylinder, and a rotating shaft is rotatably connected inside the support rod. The two ends of the rotating shaft pass through the support rod and are respectively located inside the support ring and the base. The end of the rotating shaft inside the support ring is fixed with a driving bevel gear, and the two ends inside the rotating cylinder are provided with two symmetrical driven bevel gears.

[0010] As an improvement to this solution, one set of the two driven bevel gears is fixed to the inner wall of the rotating drum, and the other set of driven bevel gears is rotatably connected to the rotating drum. Both sets of driven bevel gears mesh with the driving bevel gear, and the smoothness of gear transmission can be maintained through the rotatable driven bevel gears.

[0011] As an improvement to this solution, the base is equipped with a two-stage gear reduction assembly, which is connected to one end of the rotating shaft inside the base. A drive motor is fixed on the outer wall of the base, and the output shaft of the drive motor passes through the base and is connected to the two-stage gear reduction assembly.

[0012] As an improvement to this solution, a mounting base is fixed to the back of the protective cover, and a slider is slidably connected to the protective cover on one side of the mounting base. A disassembly screw is threaded onto the mounting base, and one end of the disassembly screw passes through the mounting base and is rotatably connected to the slider.

[0013] As an improvement to this solution, a drive motor is fixed to the back of the protective cover, one set of the two flywheels is rotatably connected to the inner wall of the protective cover and connected to the output shaft of the drive motor, and the other set of flywheels is rotatably connected to the slider.

[0014] As an improvement to this solution, handles are fixed on the side walls of the support rod and the base, and a power interface is provided at the connection between the handle and the base.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] 1. The overall design is handheld, small in size and flexible in use. By keeping the band saw parallel to the planting direction of the seedlings, it is convenient to prune large areas of shrubs. At the same time, the band saw can also be perpendicular to a single group of branches to achieve the pruning of the seedling branches. It is simple and flexible to operate and has few limitations in use.

[0017] 2. The angle adjustment mechanism and rotating components allow for flexible adjustment of the direction and angle between the band saw and the support rod, thus meeting the needs of pruning different quantities and types of seedlings.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the garden seedling pruning equipment proposed by this utility model includes a protective cover 1, two flywheels 2 are symmetrically arranged inside the protective cover 1, a band saw 3 is sleeved on the flywheels 2, a fixed seat 4 is fixed in the middle of the back of the protective cover 1, a connecting rod 6 is connected to the fixed seat 4 through an angle adjustment mechanism 5, and a support rod 8 is connected to the end of the connecting rod 6 away from the protective cover 1 through a rotating component 7, and two rectangular through holes are symmetrically arranged on the side wall of the support rod 8.

[0028] The angle adjustment mechanism 5 includes a fixed shaft 9 and a sleeve 10. The fixed shaft 9 is fixed to the fixed seat 4, and the sleeve 10 is rotatably connected to the fixed shaft 9. The connecting rod 6 is fixed to the side wall of the sleeve 10 and communicates with the inside of the sleeve 10.

[0029] The rotating assembly 7 consists of a rotating cylinder 13 and a supporting rotating ring 14, which are respectively fixed to the ends of the connecting rod 6 and the support rod 8. Meanwhile, the supporting rotating ring 14 is rotatably connected to the rotating cylinder 13.

[0030] The angle adjustment mechanism 5 and the rotating component 7 can be used to flexibly adjust the angle and direction between the protective cover 1 and the band saw 3 inside it and the user's handheld support rod 8, so as to adapt to the use of different scenarios.

[0031] like Figure 3 and Figure 5 As shown, in order to fix the angle adjustment mechanism 5 after use, a number of insertion holes 11 are evenly distributed along the circumferential direction on the side wall of the fixed shaft 9. The sleeve 10 is internally threaded with a positioning screw 12. The end of the positioning screw 12 near the fixed shaft 9 is provided with a cylindrical pin, and the pin can be inserted and removed into the insertion hole 11. At the same time, the side wall of the positioning screw 12 is provided with a circular protrusion with anti-slip grooves on the surface.

[0032] like Figure 4 As shown, a through hole is provided at the bottom of the rotating cylinder 13, and the support rod 8, which is fixedly connected to the support ring 14, passes through the through hole.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, a base 15 is fixed to one end of the support rod 8 away from the rotating cylinder 13, and a rotating shaft 16 is rotatably connected inside the support rod 8. The two ends of the rotating shaft 16 pass through the support rod 8 and are respectively located in the support ring 14 and the base 15. The end of the rotating shaft 16 located inside the support ring 14 is fixed with a driving bevel gear 17, and the two ends inside the rotating cylinder 13 are provided with two symmetrical driven bevel gears 18.

[0034] like Figure 4As shown, in order to improve the stability of the connecting rod 6 and its components when rotating, one set of the two driven bevel gears 18 is fixed on the inner wall of the rotating cylinder 13, and the other set of driven bevel gears 18 is rotatably connected to the rotating cylinder 13. Both sets of driven bevel gears 18 mesh with the driving bevel gear 17. The smooth gear transmission can be maintained through the rotatable driven bevel gears 18.

[0035] like Figure 3 and Figure 6 As shown, a two-stage gear reduction assembly 19 is provided inside the base 15 and is connected to one end of the rotating shaft 16 inside the base 15. A drive motor 20 is fixed on the outer wall of the base 15, and the output shaft of the drive motor 20 passes through the base 15 and is connected to the two-stage gear reduction assembly 19.

[0036] like Figure 2 As shown, in order to facilitate the installation and replacement of the band saw 3, a mounting base 21 is fixed on the back of the protective cover 1, and a slider 22 is slidably connected to the protective cover 1 on one side of the mounting base 21. A disassembly screw 23 is threadedly connected to the mounting base 21, and one end of the disassembly screw 23 that passes through the mounting base 21 is rotatably connected to the slider 22.

[0037] A drive motor 24 is fixed to the back of the protective cover 1. One set of the two flywheels 2 is rotatably connected to the inner wall of the protective cover 1 and connected to the output shaft of the drive motor 24. The other set of flywheels 2 is rotatably connected to the slider 22.

[0038] like Figure 1 and Figure 3 As shown, a handle 25 is fixed on the side wall of the support rod 8 and the base 15, and a power interface 26 is provided at the connection between the handle 25 and the base 15.

[0039] In practical use, the user holds the handle 25 with one hand and the anti-slip groove on the surface of the support rod 8 with the other hand. After connecting the external power supply to the power interface 26, the user turns on the switch to make the drive motor 24 drive the flywheel 2 to rotate. As the drive motor 24 rotates, the band saw 3 fitted on it rotates. At this time, the user can use the band saw 3 at the notch at the bottom of the flywheel 2 to prune the seedlings. When it is necessary to adjust the angle between the support rod 8 and the protective cover 1, the user only needs to turn on the drive motor 20, which drives the rotating shaft 16 to rotate through the secondary gear reduction assembly 19. The active bevel gear 17 fixed on the rotating shaft 16 rotates accordingly, driving the driven bevel gear 18 meshing with it to rotate. This causes the rotating drum 13, which is fixedly connected to the driven bevel gear 18, to rotate around the support ring 14. At the same time, the stability of the rotating drum 13 can be improved by using the driven bevel gear 18 on the other side.

[0040] When it is necessary to adjust the angle between the protective cover 1 and the connecting rod 6, simply move the protrusion with the anti-slip groove on the positioning screw 12 through the through holes on both sides of the connecting rod 6 to make the positioning screw 12 rotate. As the positioning screw 12 rotates, it can move along the axis of the connecting rod 6 towards the rotating cylinder 13, so that the pin at the end of the positioning screw 12 can be pulled out from the insertion hole 11, and the sleeve 10 can rotate around the fixed shaft 9. After the angle is adjusted, move the positioning screw 12 in the opposite direction to make the pin at the end of the positioning screw 12 insert into the insertion hole 11 to fix it.

[0041] The above operations allow for adjustment of the angles between the band saw 3 and the support rod 8, and between the band saw 3 and the connecting rod 6, making it convenient for users to prune seedlings at different heights and positions, thus improving user comfort.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
