Description

Technical Field

[0001] This application relates to the field of garden tools, and more particularly to a hedge trimming device. Background Technology

[0002] Hedge trimmers present numerous inconveniences and inefficiencies during use. Users need to repeatedly swing the arm to raise and lower the trimmer while walking along the hedge, a repetitive action that is not only physically demanding but also prone to causing user fatigue.

[0003] Based on our understanding of relevant technologies, we know that the tip of some hedge trimmers is connected to the pole. During use, in order to achieve a better trimming effect, the tip of the hedge trimmer needs to be adjusted to a certain angle with the pole. This design generates a torsional load on the pole, and users need to constantly resist this torsional force during the trimming process, which further increases the difficulty of operation and fatigue.

[0004] In addition, the head assembly and the pruning shears of this type of trimmer come into contact with the hedge simultaneously during trimming. As the user's arm swings the hedge trimmer back and forth, the head assembly creates resistance to the trimming process, reducing trimming efficiency. Utility Model Content

[0005] The purpose of at least one specific embodiment of this utility model is to overcome the defects of the existing technology and provide a hedge trimming device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A hedge trimming device, comprising:

[0008] Rod body;

[0009] The head assembly is mounted on the end of the rod.

[0010] Motor assembly located in the head assembly;

[0011] A shearing mechanism connected to a motor assembly, the motor assembly outputs shearing power to the shearing mechanism;

[0012] The connection node between the motor assembly and the shearing mechanism is located in the middle area of ​​the shearing mechanism, and the working plane of the shearing mechanism is adapted to the surface of the hedge to be trimmed to form a trimming working surface.

[0013] When performing hedge trimming, the operator faces the trimming surface and holds the rod, keeping the working plane of the shearing mechanism in parallel contact with the trimming surface. The operator moves to drive the shearing mechanism to perform planar trimming along the trimming surface, completing the trimming of the first working height.

[0014] An angle adjustment mechanism is provided between the shearing mechanism and the head assembly. When trimming at the second working height, the rod is adjusted to the corresponding height, and the angle between the shearing mechanism and the rod is changed through the hinge mechanism to maintain the working plane of the shearing mechanism in parallel contact with the surface of the second working height, thereby realizing multi-level continuous trimming operation.

[0015] Furthermore, the shearing mechanism is located on one side of the head assembly. In the direction perpendicular to the working plane of the shearing mechanism, there is a height difference between the shearing mechanism and the head assembly. When performing hedge surface trimming operations, the shearing mechanism first approaches the trimming working surface, and the head assembly is located behind the working plane of the shearing mechanism.

[0016] Furthermore, the shearing mechanism and the angle adjustment mechanism are located on both sides of the central axis of the rod, so that the weight on both sides of the rod is balanced.

[0017] Furthermore, the shearing mechanism includes trimming heads that extend toward both sides of the connecting node.

[0018] Furthermore, the head assembly includes a housing mounted on the end of the rod, and the motor assembly and angle adjustment mechanism are both mounted on the housing.

[0019] Furthermore, the angle adjustment mechanism includes:

[0020] An angle adjustment motor is mounted on the housing;

[0021] The worm gear is connected to the power output end of the angle adjustment motor;

[0022] The worm gear meshes with the worm.

[0023] A rotating shaft is rotatably mounted on the housing, with one end connected to a worm gear and the other end connected to a motor assembly;

[0024] The angle adjustment motor drives the worm wheel to rotate via a worm gear, and the worm wheel drives the motor assembly and shearing mechanism to rotate via a rotating shaft to achieve angle adjustment.

[0025] Furthermore, at least one of the angle adjustment motor, worm gear, and worm wheel is located on opposite sides of the central axis of the rod relative to the trimmer head, thereby balancing the weight on both sides of the rod.

[0026] Furthermore, the motor assembly includes a mounting housing, a working motor disposed within the mounting housing, a gearbox connected to the output end of the working motor, a trimmer head connected to the power output end of the gearbox, and a rotating shaft connected to the mounting housing.

[0027] Furthermore, the rod body is equipped with a first switch and a second switch. The first switch is suitable for controlling the start and stop of the working motor, and the second switch is suitable for controlling the start and stop of the angle adjustment motor.

[0028] During the operation of the working motor driving the trimmer head, the angle adjustment motor can simultaneously drive the trimmer head to adjust its angle.

[0029] Furthermore, the rotation angle of the trimmer head can be infinitely adjusted.

[0030] Furthermore, a power supply is installed on the rod, which is electrically connected to the working motor and the angle adjustment motor.

[0031] The beneficial effects of this application are as follows: 1. By optimizing the connection method between the shearing mechanism and the head assembly, when performing hedge surface trimming operations, the operator holds the pole facing the trimming work surface, and at the same time, the working plane of the shearing mechanism and the hedge to be trimmed surface always remain in parallel contact. The user only needs to hold the pole and move it along the trimming work surface to complete the trimming, without having to repeatedly swing the arm to raise and lower the equipment, which significantly reduces the operating intensity and improves the user comfort.

[0032] 2. By setting up an angle adjustment mechanism, this application allows users to adjust the angle between the shearing mechanism and the rod without stopping the trimming process, thereby achieving multi-level continuous trimming operations and significantly improving trimming efficiency;

[0033] 3. By setting the shearing mechanism and the angle adjustment mechanism on both sides of the central axis of the rod, the weight of the equipment is balanced on both sides, which effectively reduces the torsional load on the rod and makes the operation easier and more stable;

[0034] 4. The shearing mechanism is located on one side of the head assembly, so that the shearing mechanism is close to the trimming working surface first, and the head assembly is located behind the working plane of the shearing mechanism, which avoids the direct interference of the head assembly to the trimming process and improves the smoothness and efficiency of trimming.

[0035] 5. Users can adjust the rotation angle of the trimmer head in real time during the trimming process without stopping the operation or releasing the device, which simplifies the operation process and improves the user experience. Attached Figure Description

[0051] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0052] Reference Figure 1 , Figure 2 , Figure 3 , Figure 11 , Figure 13A hedge trimming device 100 includes a pole 10, a head assembly 20 assembled at the end of the pole 10, a motor assembly 30 disposed on the head assembly 20, and a shearing mechanism 40 connected to the motor assembly 30, wherein the motor assembly 30 outputs shearing power to the shearing mechanism 40.

[0053] The connection node J between the motor assembly 30 and the shearing mechanism 40 is located in the middle area of ​​the shearing mechanism 40, and the working plane P1 of the shearing mechanism 40 is adapted to the surface of the hedge to be trimmed to form the trimming working surface P2.

[0054] When performing side surface trimming of the hedge, the operator holds the rod 10 facing the trimming work surface P2, so that the working plane P1 of the shearing mechanism 40 is in parallel contact with the trimming work surface P2. The operator moves to drive the shearing mechanism 40 to perform planar trimming along the trimming work surface P2, and completes the trimming of the first working height h1.

[0055] An angle adjustment mechanism 50 is provided between the shearing mechanism 40 and the head assembly 20. When trimming at the second working height h2, the rod 10 is adjusted to the corresponding height. The angle adjustment mechanism 50 changes the angle between the shearing mechanism 40 and the rod 10, maintaining the working plane P1 of the shearing mechanism 40 in parallel contact with the surface of the second working height h2, thereby realizing multi-level continuous trimming operation.

[0056] Specifically, the technical points of this application will be explained in detail below, taking into account the pruning methods of the hedge trimming equipment 100 under four different working conditions:

[0057] When the hedge trimming device 100 trims the hedge, it mainly involves the sides and top of the hedge. In this embodiment, the height of the hedge is set to be greater than the height of a human body, and the top of the hedge is located above the operator's head.

[0058] When trimming the sides of a hedge, since the sides of the hedge are relatively high, we set the height of the hedge side below the operator's arm as the first working height h1, the height of the hedge side at the same height as the operator's arm as the second working height h2, the height of the hedge side above the operator's arm as the third working height h3, and the height of the hedge top surface above the operator's head as the fourth working height h4.

[0059] Reference Figure 3 , Figure 4When trimming the hedge at the first working height h1, since the first working height h1 is lower than the height of the operator's arm, the operator holds the pole 10, which is tilted downward relative to the human body. At this time, the working plane P1 of the shearing mechanism 40 is at an acute angle α1 relative to the central axis S1 of the pole 10. This ensures that the working plane P1 of the shearing mechanism 40 is in parallel contact with the trimming working surface P2. The operator moves and drives the shearing mechanism 40 to perform planar trimming along the trimming working surface P2, thus completing the trimming of the first working height h1.

[0060] Reference Figure 5 , Figure 6 After the first working height h1 is completed, the operator moves the hedge trimming device 100 to the starting position on the side of the hedge and performs trimming work on the second working height h2 on the side of the hedge. Since the second working height h2 is basically the same as the height of the operator's arm, when the operator holds the rod 10, the rod 10 is perpendicular to the trimming working surface P2 relative to the human body. At this time, the working plane P1 of the shearing mechanism 40 is at a right angle α2 relative to the central axis S1 of the rod 10. This ensures that the working plane P1 of the shearing mechanism 40 and the trimming working surface P2 remain in parallel contact. The operator moves and drives the shearing mechanism 40 to perform planar trimming motion along the trimming working surface P2, thus completing the trimming of the second working height h2.

[0061] Reference Figure 7 , Figure 8 After the second working height h2 is completed, the operator moves the hedge trimming device 100 to the starting position on the side of the hedge and performs trimming work at the third working height h3 on the side of the hedge. Since the third working height h3 is higher than the height of the operator's arm, when the operator holds the rod 10, the rod 10 is tilted upward relative to the human body. At this time, the working plane P1 of the shearing mechanism 40 is at an obtuse angle α3 relative to the central axis S1 of the rod 10. This ensures that the working plane P1 of the shearing mechanism 40 is in parallel contact with the trimming working surface P2. The operator moves and drives the shearing mechanism 40 to perform planar trimming motion along the trimming working surface P2, thus completing the trimming of the third working height h3.

[0062] Reference Figure 9 , Figure 10After the third working height h3 is completed, the operator moves the hedge trimming device 100 to the starting position on the side of the hedge and performs trimming work on the fourth working height h4 on the side of the hedge (the trimming working surface P3 where the fourth working height h4 is located is the top surface of the hedge). Since the fourth working height h4 is higher than the height of the operator's head, when the operator holds the rod 10, the rod 10 is also tilted upward relative to the human body. At this time, the working plane P1 of the shearing mechanism 40 is at an angle α4 relative to the central axis S1 of the rod 10. This ensures that the working plane P1 of the shearing mechanism 40 is in parallel contact with the trimming working surface P3. The operator moves and drives the shearing mechanism 40 to perform planar trimming motion along the trimming working surface P3, thus completing the trimming of the fourth working height h4.

[0063] This application ensures that the working plane P1 of the shearing mechanism 40 maintains parallel contact with the trimming working surfaces (P2 or P3) at different heights by adjusting the angle (acute angle α1, right angle α2, obtuse angle α3, and angle α4) relative to the central axis S1 of the rod 10, thereby achieving precise trimming. The tiltable design of the shearing mechanism 40 allows the operator to easily handle trimming needs at different heights without frequently changing equipment or adjusting posture. Through planar trimming motion, the shearing mechanism 40 can quickly and evenly trim the sides of the hedge, improving work efficiency. This design is suitable for various working heights from low to high and can meet the hedge trimming needs in different scenarios.

[0064] Furthermore, it should be noted that the angle adjustment mechanism 50 is an automatic adjustment mechanism. Whether the shearing mechanism 40 of the hedge trimming device 100 is performing trimming operations at the first working height h1, the second working height h2, the third working height h3, or the fourth working height h4, the user does not need to stop the operation of the motor assembly 30 when adjusting the trimming angle of the shearing mechanism 40. During the operation of the shearing mechanism 40 driven by the motor assembly 30, the user can activate the angle adjustment mechanism 50 through the switch on the rod 10 to automatically adjust the angle of the shearing mechanism 40. The angle adjustment action of the shearing mechanism 40 does not conflict with its own operation and trimming action. In this way, the user can adjust the angle of the shearing mechanism 40 without turning off the motor assembly 30 when using the hedge trimming device 100, which is quite convenient.

[0065] Furthermore, refer to Figure 11The shearing mechanism 40 includes trimming heads 401 that extend to both sides of the connecting node J, providing better balance. Specifically, this symmetrical extension design allows the shearing mechanism 40 to distribute force evenly during operation, avoiding the center of gravity shift problem common in traditional hedge trimming equipment. Therefore, when the operator adjusts the angle of the shearing mechanism 40, the hedge trimming equipment 100 can always maintain a stable posture and will not tilt forward due to the forward shift of the center of gravity, unlike traditional counter-pinch trimmers.

[0066] Furthermore, refer to Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 The shearing mechanism 40 is located on one side of the head assembly 20. There is a height difference between the shearing mechanism 40 and the head assembly 20 in the direction perpendicular to the working plane P1 of the shearing mechanism 40. When performing hedge surface trimming, the shearing mechanism 40 first approaches the trimming working surface P2, while the head assembly 20 is located behind the working plane P1 of the shearing mechanism 40. When trimming the hedge, the operator holds the rod 10 so that the working plane P1 of the shearing head 401 of the shearing mechanism 40 is in parallel contact with the trimming working surface P2. The shearing head 401 will first contact the surface of the hedge, thus trimming the branches and leaves. During the translational trimming process, the head assembly 20 will never contact the surface of the hedge, and the head assembly 20 will not interfere with the operation of the shearing head 401. Throughout the trimming process, the head assembly 20 remains behind the shearing mechanism 40 and will not contact the surface of the hedge. This design avoids secondary interference from the head assembly to the hedge, ensuring the neatness of the trimming.

[0067] Furthermore, refer to Figure 2 , Figure 13 The head assembly 20 includes a housing 201 mounted on the end of the rod 10. A controller 202 is installed in the interlayer of the housing 201. The motor assembly 30 and the angle adjustment mechanism 50 are both mounted on the housing 201.

[0068] Furthermore, the angle adjustment mechanism 50 includes an angle adjustment motor 501 mounted on the housing 201, a worm 502 connected to the power output end of the angle adjustment motor 501, a worm wheel 503 meshing with the worm 502, and a rotating shaft 504, wherein the rotating shaft 504 is rotatably mounted on the housing 201, one end of which is connected to the middle of the worm wheel 503, and the other end is connected to the motor assembly 30;

[0069] Angle adjustment motor 501 drives worm wheel 503 to rotate via worm 502. Worm wheel 503 drives motor assembly 30 and shearing mechanism 40 to rotate via rotating shaft 504 to achieve angle adjustment.

[0070] Furthermore, the motor assembly 30 includes a mounting housing 301, a working motor 302 disposed within the mounting housing 301, a transmission 303 connected to the output end of the working motor 302, a power output end of the transmission 303 connected to a trimmer head 401, and a rotating shaft 504 connected to the mounting housing 301.

[0071] The angle between the motor assembly 30 and the shearing mechanism 40 is mainly adjusted by the angle adjustment mechanism 50. During the angle adjustment process, the motor assembly 30 can drive the shearing mechanism 40 to work. For details, refer to... Figure 14 The trimmer head 401 includes a fixed blade holder 401a and a movable blade 401b disposed on one side of the fixed blade holder 401a. Additionally, an output shaft 304 is connected to the output end of the gearbox 303, and an eccentric wheel 305 is mounted on the output shaft 304. When the motor assembly 30 drives the shearing mechanism 40, the driving force of the working motor 302 is transmitted to the output shaft 304 through the gearbox 303. When the output shaft 304 rotates, the eccentric wheel 305 drives the movable blade 401b to reciprocate on one side of the fixed blade holder 401a, thereby achieving the shearing purpose. It should be noted that the structure of the trimmer head 401 is prior art and will not be described in detail in this embodiment.

[0072] In this embodiment, refer to Figure 11 When the hedge trimming device 100 is in use, from the operator's perspective facing the trimming work surface P2, it can be clearly seen that the cutting mechanism 40 and the angle adjustment mechanism 50 are located on both sides of the central axis S1 of the pole 10, ensuring that the weight of the pole 10 is balanced on both sides. In particular, this balance does not change when the angle adjustment mechanism 50 drives the cutting mechanism 40 to adjust the angle. This design effectively avoids instability or tilting caused by excessive weight on one side of the device. The symmetrical layout allows the device to maintain a stable posture during trimming operations, reducing shaking and vibration, thereby improving trimming accuracy and efficiency.

[0073] Specifically, in some embodiments, at least one of the angle adjusting motor 501, worm gear 502, and worm wheel 503 is located on both sides of the central axis S1 of the rod 10 relative to the cutting head 401, thereby balancing the weight on both sides of the rod 10. This arrangement further optimizes the weight distribution of the device and ensures the weight balance on both sides of the rod 10. By symmetrically arranging key components such as the angle adjusting motor 501, worm gear 502, and worm wheel 503, the device can maintain a stable posture when adjusting the angle, avoiding instability or tilting caused by a shift in the center of gravity. The symmetrical layout makes it easier for the operator to adjust the angle of the cutting mechanism 40 without having to exert extra force to maintain the balance of the device, thus improving the convenience and comfort of operation.

[0074] Furthermore, the rod body 10 is provided with a first switch 101 and a second switch 102. The first switch 101 is adapted to control the opening and closing of the working motor 302, and the second switch 102 is adapted to control the opening and closing of the angle adjustment motor 501.

[0075] During the operation of the working motor 302 driving the trimmer head 401, the angle adjustment motor 501 can synchronously drive the trimmer head 401 to adjust the angle. The rotation angle of the trimmer head 401 can be infinitely adjusted.

[0076] Furthermore, a power supply is installed on the rod body 10, which is electrically connected to the working motor 302 and the angle adjustment motor 501 to provide power to the working motor 302 and the angle adjustment motor 501.

[0077] In summary, by optimizing the connection between the shearing mechanism 40 and the head assembly 20, when performing hedge trimming operations, the operator holds the rod 10 facing the trimming work surface. At the same time, the working plane P1 of the shearing mechanism 40 and the hedge to be trimmed always maintain parallel contact. The user only needs to hold the rod 10 and move it along the trimming work surface P2 to complete the trimming. There is no need to repeatedly swing the arm to raise and lower the equipment, which significantly reduces the operating intensity and improves user comfort.

[0078] By setting an angle adjustment mechanism 50, this application allows users to adjust the angle between the shearing mechanism 40 and the rod 10 without stopping the trimming process, thereby achieving multi-level continuous trimming operations and significantly improving trimming efficiency.

[0079] The shearing mechanism 40 and the angle adjustment mechanism 50 are respectively set on both sides of the central axis S1 of the rod 10, so that the weight on both sides of the equipment is balanced, effectively reducing the torsional load on the rod 10, making the operation easier and more stable.

[0080] The shearing mechanism 40 is located on one side of the head assembly 20, so that the shearing mechanism 40 is close to the trimming work surface P2 first, and the head assembly 20 is located behind the shearing mechanism 40, which avoids the direct interference of the head assembly 20 to the trimming process and improves the smoothness and efficiency of trimming.

[0081] Users can adjust the rotation angle of the trimmer head 401 in real time during the trimming process without stopping the operation or releasing the device, which simplifies the operation process and improves the user experience.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
