Description

Technical Field

[0001] This utility model relates to the field of garden machinery technology, and in particular to an automated garden pruning device. Background Technology

[0002] In modern garden maintenance, the application of automated and mechanized equipment is becoming increasingly widespread, such as self-propelled lawnmowers, leaf vacuums, and various types of trimmers. These devices greatly improve the efficiency of operations in large, standardized areas.

[0003] However, existing garden machinery is designed primarily for rapid processing of open areas, with its cutting or clearing components typically having fixed dimensions and standardized working postures. This design exposes its inherent limitations when faced with the complex boundaries commonly found in garden landscapes.

[0004] Specifically, when the equipment reaches irregular areas such as wall corners, flower bed edges, paving stone gaps, or around tree roots, its standardized blades or rollers, due to structural limitations, cannot fully conform to the working surface, leaving blind spots for cleaning or trimming. Operators often need to stop the machine and use small hand tools for secondary repairs, which not only interrupts the continuity of work but also significantly reduces the overall level of automation and work efficiency.

[0005] Therefore, this utility model proposes an automated garden pruning device to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the field of automated garden pruning devices, such as the fixed structure of the cutting or cleaning components, the difficulty in fully fitting the device when dealing with complex corners and crevices, resulting in blind spots and low overall automation and work efficiency, this utility model aims to provide an automated garden pruning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an automated garden pruning device, comprising: a machine body, a first rotating shaft, a second rotating shaft, and a cutter head; the first rotating shaft and the second rotating shaft are rotatably connected to the machine body, and the cutter head is fixedly connected to one end of the second rotating shaft; and an adjustment component.

[0008] The adjustment component is a composite structure that integrates a servo transmission mechanism and a blade mechanism. The servo transmission mechanism includes a servo motor, a chain, a first gear, and a second gear, while the blade mechanism includes a connecting rod and a saw blade.

[0009] Furthermore, the machine body, the first rotating shaft, the second rotating shaft, and the adjustment component are combined in the following manner: the servo motor is fixed to the machine body and is connected to the first gear through the chain drive; the first gear is fixedly sleeved on the first rotating shaft, and the second gear is fixedly sleeved on the second rotating shaft, forming a precise adjustment path for the cutter head; at the same time, the serrated blade is fixedly connected to the other end of the connecting rod, forming a retractable supplementary cutting structure.

[0010] Preferably, the adjustment assembly further includes a bolt that passes through the flag hinge and engages with the machine body threadedly. By tightening or loosening the bolt, the connecting rod and the serrated blade thereon can be easily locked at any extension angle, thereby adapting to working environments of different widths or depths.

[0011] Preferably, the adjustment assembly further includes a flag hinge hinged to the body, which allows for overall tilt adjustment of the body, enabling the cutter head and the serrated blades to approach and process hard-to-reach corners from more angles.

[0012] Preferably, the automated garden pruning device further includes a cleaning component that integrates multiple functional parts, including an anti-tangling roller brush and a centrifugal fan installed inside the machine body, as well as an air duct; one end of the air duct is connected to the exhaust port of the centrifugal fan to form a highly efficient negative pressure suction channel.

[0013] Preferably, the cleaning assembly further includes a drive motor, a drive helical gear, a driven helical gear, and a brush roller shaft. The drive motor drives the brush roller shaft, which is fixed to the driven helical gear, to rotate through the meshing transmission of the drive helical gear and the driven helical gear. The anti-tangling roller brush is coaxially and fixedly connected to the brush roller shaft, ensuring the synchronicity of the combing and dispersing actions and the stability of the power output.

[0014] Preferably, the automated garden pruning device further includes auxiliary components, which include at least a grass collection box, and the machine body is provided with a conveying pipe. The grass collection box is installed inside the machine body to prevent it from being exposed and damaged by external impacts.

[0015] Preferably, the bottom of the machine body is provided with wheels for movement, a handrail is fixedly connected to one side of the machine body, a control switch is provided on the handrail for human-machine interaction, and heat dissipation holes are also provided on the machine body to ensure the stable operation of the internal power components.

[0016] Preferably, the auxiliary component further includes a handle, which is securely mounted on the outer wall of the hay collection box, facilitating the operator to pull out, empty, and return the hay collection box to its original position.

[0017] Preferably, the auxiliary components also include a slide rail and a flow guide pad. The grass collection box is detachably slidably installed on the machine body via the slide rail, enabling quick assembly and disassembly.

This utility model solves the problem that existing garden devices have a simple structure, making it difficult to reach narrow areas such as corners and crevices, resulting in blind spots and inability to accurately fit uneven edges. It is achieved by setting up a composite adjustment component that drives the cutter head to finely adjust the angle by a servo motor and drives the saw blade to extend independently by a connecting rod. This achieves the technical effect of high-precision adaptive pruning of complex corner areas without blind spots, and significantly improves the thoroughness and precision of a single operation.

[0020] 2. This utility model solves the problem of clogging and low efficiency of existing cleaning devices when dealing with large or easily tangled debris by coordinating the anti-tangling roller brush, centrifugal fan, cutting disc installed in the air duct and silicone comb. It achieves the technical effect of integrating combing, dispersing, cutting and crushing, anti-tangling and high-efficiency suction, and improves the equipment's ability to handle complex ground debris and the stability of continuous operation.

[0021] 3. This utility model integrates multiple functions such as ground cleaning, debris crushing, and corner finishing into a single push-type body, solving the problems of traditional garden maintenance requiring multiple independent devices, cumbersome operation, time-consuming conversion, and low overall efficiency. It achieves the technical effect of multi-purpose machine, simplified operation process, reduced equipment investment, and significantly improved overall garden maintenance efficiency.

The auxiliary component 7 also includes a flow guide pad 74, which is installed inside the delivery pipe 6 to guide debris to enter smoothly. In addition, the auxiliary component 7 also includes a silicone comb 73, which is fixedly installed inside the body 2, with its comb teeth facing the anti-tangling roller brush 35, to assist in combing and prevent debris from tangling.

[0029] Based on the above embodiments, the present invention also includes the following preferred technical solutions: As a further preferred embodiment of the adjustment assembly 9, in order to stably fix the serrated blade 94 at a specific working angle, the adjustment assembly 9 also includes a bolt 92, which passes through a flag hinge 91 and is threaded into the body 2; and, in order to enable the entire device to adapt to uneven corner terrain, the adjustment assembly 9 also includes a flag hinge 91, which is hinged to the body 2.

[0030] As a further preferred embodiment of the cleaning assembly 3, in order to achieve synchronous and efficient rotation of the brush roller shaft 31 and the anti-tangling roller brush 35, the cleaning assembly 3 also includes a drive motor 32, a drive helical gear 33 and a driven helical gear 34.

[0031] As a further optimization of the auxiliary component 7, in order to facilitate the installation, disassembly and cleaning of the grass collection box 71, the auxiliary component 7 also includes a slide rail 75 and a handle 72. The grass collection box 71 is detachably slidably connected to the machine body 2 via the slide rail 75, and the handle 72 is set on the outer wall of the grass collection box 71. At the same time, in order to ensure that debris smoothly enters the grass collection box 71 through the delivery pipe 6, the auxiliary component 7 also includes a flow guide pad 74, which is installed inside the delivery pipe 6.

[0032] In another preferred embodiment, in order to help comb out debris and prevent it from getting tangled, the device also includes a silicone comb 73, which is fixedly connected to the inside of the body 2 and has its comb teeth facing the anti-tangling roller brush 35.

[0033] As a preferred choice for the basic structure of the device, in order to enable movement, operation and ensure long-term stable operation, the bottom of the body 2 is equipped with wheels 1, and a handrail 4 is fixedly connected to one side of the body 2. The handrail 4 is equipped with a control switch 5, and the body 2 is also equipped with heat dissipation holes 8.

[0034] The working principle of this automated garden pruning device is as follows: During standard cleaning operations, the operator holds the handle 4 and starts the equipment via the control switch 5, causing the wheels 1 to drive the machine body 2 to move. The drive motor 32 inside the cleaning component 3 operates, driving the brush roller shaft 31 and the anti-tangling roller brush 35 to rotate synchronously through the meshing of the drive helical gear 33 and the driven helical gear 34, thus combing and breaking up the debris on the ground. At the same time, the centrifugal fan 36 starts, creating a negative pressure airflow in the air duct 37 and the conveying pipe 6, which sucks in the debris. During the conveying process, the cutter disc 13, driven by the chain 10, the first gear 11 and the second gear 12, completes the cutting pre-treatment through the cooperation of the first rotating shaft 14 and the second rotating shaft 15. Subsequently, with the assistance of the silicone comb 73 of the auxiliary component 7, the debris is guided by the guide pad 74 and finally enters the grass collection box 71 along the slide rail 75. Throughout the process, the heat dissipation holes 8 on the machine body 2 continuously dissipate heat for each power component. After the grass collection box 71 is full, it is pulled out for cleaning by the handle 72.

[0035] When encountering difficult-to-handle areas such as corners and narrow gaps, the tilt angle of the machine body 2 is adjusted by adjusting the flag-shaped hinge 91 of the adjustment component 9. At the same time, the bolt 92 is tightened to fix the connecting rod 93, which drives the serrated blade 94 to extend downward and close to the working surface for supplementary cutting. Simultaneously, the servo motor 95 is started, and through the precise transmission of the chain 10, the first gear 11, the second gear 12, the first rotating shaft 14 and the second rotating shaft 15, the rotation direction of the cutter disc 13 is finely adjusted so that it can accurately cut along the gaps or protruding edges. Through the above-mentioned combined synergistic effect of the adjustment component 9, this utility model solves the problem of incomplete corner operations caused by structural limitations in the prior art.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
