Description

Technical Field

[0001] The present invention relates to the technical field of garden pruning equipment, and particularly relates to a garden hedge trimming device. Background Art

[0002] Garden hedges generally refer to plant walls used to separate spaces, demarcate boundaries, and guide lines of sight in garden landscapes. They are usually formed by densely planting shrubs or small trees at close plant spacings, forming a single-row or double-row regular planting pattern. It can provide ornamental and landscape effects, and at the same time can provide a quiet and comfortable environment for people. Garden hedges are usually planted in public or private places such as parks, squares, and courtyards, and their design and layout need to consider the coordination and aesthetics with the surrounding environment.

[0003] In addition, garden hedges also include road hedges. The so-called road hedges refer to plant walls planted on both sides or in the central green belt of roads, and their main functions are to prevent soil erosion, beautify the road environment, absorb vehicle noise and exhaust, and improve traffic safety. Road hedges usually select plants with strong adaptability, easy maintenance, and resistance to pruning, such as evergreen shrubs like Chinese juniper and boxwood, or low hedge plants, and are widely used in urban roads.

[0004] Although garden hedges and road hedges are slightly different in function and role, they are all green belts set up to beautify the environment and improve the ecological quality, and are an important part of urban greening and landscape construction.

[0005] However, whether it is a road hedge or a garden hedge, the pruning of hedge shrubs is a very important horticultural task, which can keep the hedge clean and beautiful, and improve road safety and driving comfort. When pruning hedges, it is usually necessary to pay attention to pruning in the horizontal and vertical directions.

[0006] Horizontal pruning mainly involves the trimming of the top and sides of the hedge. Through pruning, the height of the hedge can be kept consistent, and the appearance in each season is relatively uniform. When pruning, the height of the hedge should be maintained within a certain range, generally not exceeding 1 meter. If the hedge is too high, it may block the line of sight of driving, posing a hidden danger to road safety; while if the hedge is too short, it may affect the greening effect and landscape aesthetics.

[0007] For vertical pruning, it mainly involves the trimming of the sides and contours of the hedge. When pruning, the sides of the hedge should be kept flat and the contours should be clear, avoiding branches extending out of the green belt and invading the road driving area, which may affect pedestrians and vehicles. Pruning workers usually use flat shears or vertical pruning machines for operation. When pruning, the inner and outer vertical directions of the hedge should be trimmed properly to keep the overall shape of the hedge beautiful. After pruning, the contours of the hedge should be neat and consistent, the lines should be smooth, and the overall effect should be beautiful without affecting the road.

[0008] In a multi-functional integrated machine for landscaping pruning with a publication number of CN117356279A, it includes a support frame. The support frame includes a horizontal plate and a vertical plate. An elevating mechanism is installed on the vertical plate. A pruning box is rotatably connected to the elevating mechanism. A guiding mechanism is provided at the bottom of the vertical plate. The guiding mechanism abuts against the surface of the curb. The pruning box and the vertical plate are connected by a connecting member. The present invention can achieve the trimming of various working objects, such as the top trimming of hedges, the side trimming of hedges, and the lawn trimming. It can move forward with the help of a vehicle without being carried manually. With the design of the connecting member, it can be pressed and rotated when encountering a tree, thus realizing tree obstacle avoidance, solving the deficiencies existing in the prior art. This technical device can be switched between two modes of horizontal trimming and vertical trimming. However, this technical device uses a rotating shaft and a sliding rail to control the position switching of the pruning box, and then applies to the horizontal or vertical trimming mode. But the pruning box of this technical device can only trim at the pruning blade surface, and the trimming range is only limited to one side. Secondly, when this technical device rotates and adjusts, it cannot fix the angle. Therefore, this technical device can only perform trimming at horizontal and vertical angles and cannot perform special-shaped garden trimming by fixing the angle. Therefore, this technical device is only applicable to trimming the hedgerow shrubs on the road and can only trim square hedges. Therefore, this technical device can only perform trimming at horizontal and vertical angles, and the applicable range and trimming range are small. In addition, the bottom of this device adopts a right-angle guiding wheel design that matches the curb. This design allows the user to push forward smoothly and improves the working stability. However, the user still needs to control the center of gravity of this device, and the user needs to hold it. After working for a long time, it may cause the center of gravity of the device to be unstable and then lead to a reduction in the working qualification rate. Therefore, this device still lacks in the stability of the center of gravity. Summary of the Invention

[0009] The present invention provides a garden hedge trimming device, which solves the problem in the prior art devices that due to the need for stable guiding of the device, a right-angle guiding wheel design matching the curb is set for the device, so that the center of gravity of the device needs to be intervened and controlled by the user. After the user works for a long time, it may cause the center of gravity of the supported device to be unstable and then lead to a reduction in the working qualification rate.

[0010] Secondly, it solves the problem that in a device that can support switching between horizontal and vertical, the angle cannot be fixed during the switching process, and the tool only supports single-sided trimming, making this technical device only applicable to the trimming of hedges on the road, resulting in a small applicable range.

Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Garden hedges generally refer to plant walls used to separate spaces, demarcate boundaries, and guide lines of sight in garden landscapes. They are usually formed by densely planting shrubs or small trees at close plant spacings, forming a single-row or double-row regular planting form. It can provide ornamental and landscape effects, and at the same time can also provide a quiet and comfortable environment for people. Garden hedges are usually planted in public or private places such as parks, squares, and courtyards, and their design and layout need to consider the coordination and aesthetics with the surrounding environment.

[0033] Hedges can be trimmed into various shapes and can be combined with different types of trees to improve the ornamental effect and artistic value. In addition, hedges have multiple functions in garden landscape design, including reducing noise, beautifying the environment, enclosing sites, dividing spaces, serving as the background for statues, fountains, small garden facilities, etc.

[0034] In addition, garden hedges also include road hedges. The so-called road hedges refer to plant walls planted on both sides or in the central green belt of roads, and their main functions are to prevent soil erosion, beautify the road environment, absorb vehicle noise and exhaust gas, and improve traffic safety. Road hedges usually select plants with strong adaptability, easy maintenance, and resistance to pruning, such as evergreen shrubs like Chinese juniper and boxwood, or low hedge plants, and are widely used in urban roads.

[0035] Although garden hedges and road hedges are slightly different in function and role, they are both green belts set up to beautify the environment and improve the ecological quality, and are an important part of urban greening and landscape construction.

[0036] However, whether it is a road hedge or a garden hedge, pruning the hedge shrubs is a very important gardening task. It can keep the hedge neat and beautiful, and improve road safety and driving comfort. When pruning a hedge, it is usually necessary to pay attention to pruning in the horizontal and vertical directions.

[0037] Horizontal pruning mainly involves tidying up the top and sides of the hedge. Through pruning, the height of the hedge can be kept consistent, and the appearance in each season is relatively uniform. When pruning, the height of the hedge should be maintained within a certain range, generally not exceeding 1 meter. If the hedge is too high, it may block the driver's line of sight and pose a hidden danger to road safety; while if the hedge is too short, it may affect the greening effect and landscape beauty.

[0038] For vertical pruning, it mainly involves tidying up the sides and contours of the hedge. When pruning, the sides of the hedge should be kept flat and the contours should be clear, avoiding branches extending out of the green belt and invading the road driving area, which may affect pedestrians and vehicles. Pruning workers usually use flat shears or vertical pruning machines when pruning. When pruning, the inner and outer vertical directions of the hedge should be pruned properly to keep the overall shape of the hedge beautiful. After pruning, the contours of the hedge should be neat and consistent, the lines should be smooth, and the overall effect should be beautiful without affecting the road.

[0039] By pruning in the horizontal and vertical directions, the hedge shrubs beside the road can achieve the following effects: 1. Improve road safety: The neat and consistent hedge can reduce visual blind spots and improve driving safety.

[0040] 2. Enhance landscape beauty: The neatly pruned hedge not only improves the greening effect of the road but also adds a sense of beauty to the urban landscape.

[0041] 3. Promote the healthy growth of plants: Reasonable pruning can promote the photosynthesis and growth of plants, which is beneficial to the healthy growth of plants.

[0042] 4. Reduce the occurrence of diseases and pests: Pruning can promote the ventilation and light transmission of plants, reduce the growth environment of germs and pests, and thus reduce the occurrence of diseases and pests.

[0043] In the devices of the prior art, due to the need for stable guidance of the device, a right-angle guide wheel design matching the curbstone is provided for the device, so that the center of gravity of the device requires the user to intervene and control. After long-term work by the user, it may lead to the problem that the center of gravity of the supported device is unstable, resulting in a decrease in the work qualification rate. Secondly, in the devices that can support switching between horizontal and vertical, the angle cannot be fixed during the switching process, and the cutter only supports single-sided trimming, making this technical device only applicable to the trimming of road green hedges, resulting in a small application range. Moreover, the single-sided trimming cutter leads to problems such as a small trimming angle and a small trimming range. To solve the above problems, this embodiment is provided. This embodiment includes a chassis 1, a lifting sleeve rod 1.1, a guide wheel 1.2, a universal wheel 1.3, a handrail frame 2, a handrail 2.1, a cylinder connecting rod 2.2, a transverse sliding rail 2.3, a hydraulic rod 2.4, a handrail rod 2.5, a distribution box 3, a storage port 3.1, a lifting cylinder 4, an adjusting rod 4.1, an electric saw 5, a saw blade 5.1, a blade fixing screw 5.2, a grip 5.3, a switch 5.4, a turntable 6, a turntable fixing screw 6.1, a turntable seat 7, and a driving motor 8.

[0044] Referring to Figures 1 to 6 This is Embodiment 1. Embodiment 1 is a garden green hedge trimming device. Referring to Figure 1 This is the front view schematic diagram of the overall structure of Embodiment 1, Figure 2 This is the exploded schematic diagram of the overall structure of Embodiment 1, Figure 3 This is the rear view schematic diagram of the overall structure of Embodiment 1. Embodiment 1 includes a chassis 1, which is a frame-shaped structure, and a lifting cylinder 4 perpendicular to the ground is provided on the chassis. Parallel to the lifting cylinder, lifting sleeve rods 1.1 are fixed on both sides of the lifting cylinder; a handrail frame 2, which is composed of two parallel handrail rods 2.5, and a transverse sliding rail 2.3 is provided between the two handrail rods. The transverse sliding rail is perpendicular to the two handrail rods and connects and fixes the two handrail rods 2.5. A turntable 6 is slidably fixed on the transverse sliding rail. The other end of the turntable is fixed with a turntable seat 7. The turntable seat is rotatably connected to the electric saw. The electric saw can rotate around the center of the turntable seat. The handrail frame also has a cylinder connecting rod 2.2, and the cylinder connecting rod matches the lifting cylinder.

[0045] Referring to Figure 2This is an exploded view of the overall structure of Embodiment 1. In the figure, the chassis is in a U-shape and consists of 3 rods. The design of this U-shaped chassis has good stability and practicability and can be widely applied to various lifting devices. The U-shaped structure of the chassis enables the entire device to have a strong load-bearing capacity and can cope with various complex working environments. Its unique design concept and delicate structure make the lifting process smoother and greatly improve work efficiency. Universal wheels 1.3 are provided at the bottoms of the two side rods. The two side universal wheels endow the device with good mobility and facilitate operation at different locations. The design of the guide wheels 1.2 makes the device more stable during movement and avoids the shaking problem caused by uneven ground. One of the side rods is also provided with a guide wheel 1.2. The guide wheel is parallel to the ground and perpendicular to the rod where the guide wheel is located. The guide wheel is used to contact the curbstone. When the chassis is pushed, the guide wheel 1.2 rolls in contact with the side wall of the curbstone, thereby providing a guiding function for the device in this embodiment and making the device in this embodiment work more stably. The lifting cylinder is located on the middle rod of the chassis and at the middle of the rod where it is located. Secondly, the lifting cylinder 4 is located on the middle rod of the chassis. Such a design makes the lifting force distribution more uniform and further improves the stability of the device. Moreover, the lifting cylinder is located in the middle of the rod, making the force received by the lifting sleeve rod more balanced during the lifting process, thereby reducing wear and increasing the service life. Finally, the lifting sleeve rods 1.1 are located at the two ends of the rod where the lifting cylinder is located. This design enables the lifting sleeve rods to freely expand and contract during the lifting process, greatly increasing the lifting range. At the same time, this design also makes the lifting process smoother and avoids the jitter problem caused by the fixed length of the lifting sleeve rod.

[0046] The handrail frame 2 is of a frame structure. The transverse movement slide rail 2.3 is fixed on the hydraulic rod 2.4, and the hydraulic rod is parallel to the transverse movement slide rail. The hydraulic rod is fixed between the two handrail rods and connects and fixes the two handrail rods 2.5. The cylinder connecting rod 2.2 is fixed on the outer shell of the hydraulic rod and is integrated with the handrail frame. Being integrated helps to improve the integrity of the device and reduce the occurrence of internal abnormal noises. The cylinder connecting rod is inserted into the lifting cylinder. The two handrail rods of the handrail frame are bent near the ends of the transverse movement slide rail to form handrails 2.1. The outer periphery of the handrails is wrapped with anti-slip rubber sleeves for the operator to hold and increase anti-slip performance.

[0047] The lifting cylinder 4 is a driving device, and the rising and falling of the handrail frame are achieved by controlling the air pressure in the cylinder. Under the action of the lifting cylinder, the handrail frame can move in the vertical direction to meet the height requirements of different usage scenarios.

[0048] To further improve the operation convenience of the armrest frame, an operation panel is also provided on the armrest frame. The operation panel includes a start button, a stop button, and an adjustment button. Users can control the ascent, descent, and lateral movement of the armrest frame through the operation panel, which greatly facilitates the use process. The operation panel can be fixed on the armrest rod of the armrest frame, making it convenient for users to view and operate during operation.

[0049] The hydraulic rods and cylinder connecting rods of the armrest frame are both made of high-strength materials, having good anti-bending and anti-tensile properties, ensuring the stability and durability of the armrest frame during long-term use. At the same time, the lateral movement slide rails and guide rods of the armrest frame also adopt high-precision and high-strength materials to ensure the accuracy and safety of the armrest frame under various working conditions.

[0050] Refer to Figure 3 It is a rear view schematic diagram of the overall structure of Embodiment 1. In the figure, the lateral movement slide rail 2.3 consists of a slide rail housing and a lateral movement guide rod, and the slide rail housing is connected to the hydraulic rod housing to form an integral body. The lateral movement guide rod and the hydraulic rod are connected and fixed by a turntable fixing screw 6.1. And a distribution box 3 is also fixed on the slide rail housing, and a storage opening 3.1 is provided on the upper layer of the distribution box.

[0051] The design of the lateral movement slide rail has a wide range of applications in the engineering field. Its excellent performance provides reliable mobile support for various engineering machinery and equipment. During use, users can precisely control the lateral movement slide rail through the hydraulic rod according to actual needs to achieve the efficient movement of the equipment in complex environments.

[0052] The connection design between the slide rail housing and the hydraulic rod housing makes the entire lateral movement slide rail have high stability and durability. In harsh environments, this connection method can ensure the normal operation of the lateral movement slide rail and extend its service life. At the same time, the lateral movement guide rod and the hydraulic rod connected and fixed by the turntable fixing screw enable the lateral movement slide rail to still maintain excellent movement performance under heavy pressure.

[0053] In addition, the distribution box fixed on the slide rail housing provides a convenient power supply solution for users. At the construction site, users can provide stable power for the equipment through the distribution box to ensure the normal operation of the equipment. The design of the storage opening on the upper layer of the distribution box facilitates users to store various tools and accessories, thus reducing the complexity of on-site construction.

[0054] To meet the use requirements in different scenarios, the lateral movement slide rail can also be customized according to user requirements. For example, at a construction site with narrow space, the lateral movement slide rail can be designed into a more compact structure to adapt to the complex operation environment. And in occasions that require long-term continuous operation, the load-bearing capacity and wear resistance of the lateral movement slide rail can be specifically improved to ensure the stable operation of the equipment.

[0055] A turntable fixing screw is fixed with a turntable near one end close to the transverse guide rod. The turntable is circular, and a number of fixing holes are distributed circumferentially on the turntable, which can be used to connect other devices or parts. The turntable fixing screw passes through the center of the turntable and is fixed to the turntable seat. The turntable seat is used to connect and fix the turntable. The turntable seat and the turntable are fixed into a whole by a number of screws, which is conducive to improving the overall stability of the device in this embodiment.

[0056] Refer to Figure 4 It is the front view schematic diagram of the structure of the electric saw in Embodiment 1. Refer to Figure 5 It is the front view schematic diagram of the connection structure between the electric saw and the turntable in Embodiment 1. In the figure, the electric saw includes a grip and a saw blade. The grip is rotatably fixed to the turntable seat, and one end of the grip 5.3 is provided with a holding port matching the hand shape in a penetrating manner, and a switch 5.4 is arranged in the holding port. In addition, the grip is connected to the saw blade 5.1. The saw blade is strip-shaped, and a number of blades are fixed thereon by blade fixing screws. The working principle of the electric saw is as follows: When the user holds the grip and presses the switch in the holding port, the electric saw starts to work. The turntable seat of the electric saw drives the blades of the saw blade to rotate, realizing the cutting of materials such as wood and steel. As the blades of the saw blade rotate, the blades gradually cut the material into the required shape and size.

[0057] In order to improve the service life and cutting efficiency of the electric saw, the electric saw also has the following characteristics: 1. The saw blade material is selected as high-quality stainless steel, which has good wear resistance and corrosion resistance, ensuring the stability of the saw blade during long-term use.

[0058] 2. The grip is designed according to ergonomics, which helps the user maintain a comfortable posture during operation and reduces user fatigue.

[0059] 3. The electric saw is equipped with a built-in battery, which is convenient for users to use in a power-free environment and meets the needs of outdoor operations.

[0060] 4. In addition, the electric saw can also be equipped with different saw blades to meet the cutting needs of different materials. For example, for the cutting of metal materials, saw blades with higher hardness can be selected; for the cutting of wood, softer saw blades can be selected.

[0061] In addition, the electric saw in this embodiment is a handheld electric saw, and the electric saw and the turntable seat are detachably connected. Different electric saws can be replaced according to the types and shapes of pruning, thereby improving the adaptability and making the applicable range of the device in this embodiment wider.

[0062] The turntable base is of a cylindrical structure. One side of the turntable near the motor is fixedly attached to the turntable base. The turntable base is rotationally connected to the driving motor, and the driving motor is integrally fixed to the electric saw.

[0063] On the basis of Figure 1 , Figure 2 , Figure 3 Example 2 is obtained by further refining the main technical solutions such as the shape, structure, positional relationship, and connection relationship in Example 1. Example 2 is the same as Example 1 and is a garden hedge trimming device, mainly including the following parts: a chassis, a handrail frame, a lifting cylinder, a lifting sleeve rod, a transverse sliding rail, a turntable, a turntable base, an electric saw, and a cylinder connecting rod.

[0064] The chassis is still of a frame structure and is used to support the entire device. A lifting cylinder perpendicular to the ground is provided thereon. On both sides of the lifting cylinder, lifting sleeve rods parallel to the lifting cylinder are fixed. The function of the lifting sleeve rods is to facilitate the adjustment of the height of the electric saw to meet the requirements of different usage scenarios. However, the design of the lifting cylinder has changed. The internal structure of the lifting cylinder is adjusted to have a double-layer sealing structure, which can improve the sealing performance of the lifting cylinder and reduce the possibility of leakage.

[0065] In addition, the handrail frame in this embodiment has also been improved. The handrail frame is composed of two handrail rods, which are placed in parallel and the distance between them is adjustable. Between the two handrail rods, a transverse sliding rail is provided, which is perpendicular to the two handrail rods and connects and fixes the two handrail rods. Different from Example 1, in this embodiment, a plurality of fixed grooves are provided on the transverse sliding rail, and the turntable can slide in these grooves. In this way, the turntable can have multiple fixed points during transverse movement, improving the stability.

[0066] The handrail frame is also provided with a cylinder connecting rod, which is matched with the lifting cylinder. Through the cooperation of the cylinder connecting rod and the lifting cylinder, the height of the handrail frame can be adjusted, enabling the user to find a suitable height when operating the electric saw.

[0067] Example 3 is a further improvement based on Example 2. In Example 3, the designs of the chassis and the handrail frame are the same as those in Example 2. For the lifting cylinder, certain optimizations are made in this embodiment. Specifically, one end of the cylinder connecting rod is connected to the piston of the lifting cylinder, and the other end is connected to the handrail frame. In this way, during the operation of the lifting cylinder, the height of the handrail frame can be effectively controlled to keep it stable.

[0068] In addition, Example 3 has also improved the electric saw. The motor power of the electric saw is increased and the rotational speed is increased, so that a faster cutting speed can be achieved during the cutting process. At the same time, the electric saw is also equipped with a function of automatically adjusting the cutting depth, making the cutting process more intelligent.

[0069] In terms of the driving mode of the electric saw, the driving motor in the embodiment 1 or 2 can be an electric motor or a pneumatic motor. The electric motor has a higher speed and output power, and is suitable for cutting objects with higher hardness; while the pneumatic motor is slightly inferior to the electric motor in speed and output power, but its advantages are low noise and small vibration, and it is suitable for use in noise-sensitive occasions.

[0070] In terms of operation method, this embodiment provides an adjustment rod, and the lifting cylinder also includes an adjustment rod, which is installed at the end of the lifting cylinder and extends in a direction far away from the electric saw. The lifting and lowering of the lifting cylinder is controlled by turning the adjustment rod on the lifting cylinder, which in turn drives the armrest to be raised and lowered, thereby controlling the working height of the electric saw. In addition, the design of the adjustment rod also takes ergonomics into consideration, making the operation more convenient and comfortable.

[0071] Secondly, the piston rod diameter of the lifting cylinder is increased, which can improve the bearing capacity of the lifting cylinder. In order to ensure the service life of the lifting cylinder and the adjusting rod, the material of the lifting cylinder is selected from high-quality aluminum alloy, which has the characteristics of light weight, high strength and corrosion resistance. High-quality seals are used inside the lifting cylinder to ensure the stability and sealing performance of the cylinder movement. In addition, the lifting cylinder is also equipped with dust and waterproof devices to cope with harsh working environments.

[0072] In order to ensure the stability of the electric saw during cutting, the lifting cylinder is also equipped with an anti-shake device. During the operation of the electric saw, the anti-shake device senses the vibration frequency of the saw blade and adjusts the action of the lifting cylinder in real time, thereby reducing the vibration of the saw blade and improving the cutting quality.
