Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of equipment for pruning hedges, specifically to a splash-proof device for hedge pruning and a vehicle-mounted hedge trimmer. Background Technology
[0002] The green hedges in the center of highways effectively prevent glare from oncoming headlights at night. However, these hedges also require regular trimming. Specialized vehicle-mounted hedge trimmers are typically used for this purpose.
[0003] See early hedge trimmer blade holders Figure 5 As shown, there are no splash guards, and when used, the pruned branches are easily knocked into the opposite lane, affecting the passage of vehicles on the other side.
[0004] Purchasing a new cutter or hedge trimmer would be a significant expense.
[0005] Therefore, the applicant designed a splash guard for hedge trimming that can be added to and improved early hedge trimmers on the market to reduce replacement costs. Summary of the Invention
[0006] To address the technical problem of early hedge trimmers lacking effective anti-splash measures, as described in the background section, this invention provides an anti-splash device for hedge trimming and a vehicle-mounted hedge trimmer.
[0007] The technical solution of this utility model is as follows: A splash guard for hedge trimming, comprising a blade holder and an outer protective plate fixedly connected to one end.
[0008] The outer protective plate has an L-shaped cross-section, extending along the direction perpendicular to the length of the tool holder, and its length is greater than the length of the trimmer at the lower end of the tool holder. It includes a horizontal part and a vertical part. The horizontal part is flush with the upper end of the tool holder, and the vertical part is vertically set on the outer side of the end of the tool holder, with its bottom end lower than the bottom surface of the trimmer at the lower end of the tool holder.
[0009] The lower end of the vertical part of the outer protective plate is fixedly connected to the bottom surface of the tool holder by a lower connector. The lower connector includes two L-shaped brackets, which are located on both sides of the lower end of the tool holder and are fixedly connected to the lower end surface of the tool holder and the inner side of the vertical part, respectively. Two side connecting plates are also fixed in the middle of the inner side of the outer protective plate, and the outer ends of the two side connecting plates are fixedly connected to the side of the tool holder. An upper connector is fixed to the horizontal end of the outer protective plate, and the upper connector is fixedly connected to the upper surface of the tool holder.
[0010] By welding the outer protective plate to one end of the blade holder, a strong protection is formed at the front and top of the trimmer, which can effectively prevent the cut branches from flying forward or upward, improving the performance of early hedge trimmers.
[0011] Moreover, compared to the current hedge trimmers, which only have a protective plate of the same width integrally formed with the blade holder to save costs and do not cover the material throwing range of the trimmer blades, the newly added outer protective plate has a larger protective area.
[0012] The newly added outer protective plate is fully connected and fixed to the original blade holder through the lower connector, side connector, and upper connector, preventing the outer protective plate from being detached from the blade holder due to impact from branches during pruning.
[0013] As one implementation method, the L-shaped frame is made of two rectangular tubes welded together, which can reduce the counterweight, and the bottom end does not exceed the bottom end of the vertical part of the outer protective plate.
[0014] As a further preferred option, the lower connector also includes a crossbar, which is connected between the corners of the two L-shaped frames. This improves the strength of the lower connector and seals the gap between the bottom of the tool holder and the vertical part of the outer guard plate.
[0015] In this way, the top surface of the tool holder fits tightly with the horizontal part of the outer protective plate, the side surface fits tightly with the side connecting plate, and the bottom surface fits tightly with the lower connecting piece, achieving a seamless connection between the tool holder and the outer protective plate, which can effectively prevent twig fragments from remaining at the junction of the two.
[0016] As a further improvement, the area directly opposite the cutter holder on the vertical section of the outer protective plate is not only the main stress zone for splintering, but also requires multiple welds during connection with the cutter holder. Therefore, a reinforcing plate is installed between the lower connector and the vertical section of the outer protective plate. The height of the reinforcing plate is the same as that of the vertical section, and the width is the same as the width of the cutter holder. This is to improve the strength of the middle section of the outer protective plate.
[0017] In one embodiment, the side connecting plate is a right-angled triangular plate, with its two right-angled sides fixedly connected to the horizontal and vertical parts of the outer protective plate, respectively, and its hypotenuse fixedly connected to the side of the tool holder.
[0018] In one embodiment, the outer protective panel has an upward-curved edge at the horizontal end, an inwardly extending downward-curved edge at the vertical end, and vertically inward-curved side edges on both sides. This flanged design around the outer protective panel further enhances its strength, effectively resisting impacts from flying branches.
[0019] Furthermore, the length of the upper connector is greater than the width of the tool holder, one side is fixedly connected to the outer side of the upper flange, and the bottom surface is fixedly connected to the upper end surface of the tool holder.
[0020] Based on usage experience, although the outer protective plate of this utility model is longer than that of the prior art and has a larger shielding space, the two sides sometimes have the problem of warping. Therefore, a reinforcing member is fixed at the root of the inner side of the side flange to better resist impact deformation.
[0021] The present invention addresses a tool holder where the bottom surface height is higher than the side bottom height, and the upper length is shorter than the lower length.
[0022] This utility model also provides a vehicle-mounted hedge trimmer, with the aforementioned anti-splash device for hedge trimming connected to the end of the trimming arm.
[0023] Through the above design, the anti-splash device for hedge trimming and the vehicle-mounted hedge trimmer of this utility model, by welding the outer protective plate to one end of the blade holder, form a strong protection at the front and top of the trimmer blades, which can effectively prevent the cut branches from splashing forward or upward, thus improving the performance of early hedge trimmers.
[0024] Moreover, compared to the current hedge trimmers' protective panels, which, in an effort to save costs, are merely integrated protective plates of the same width as the blade holder and do not cover the area where the trimmer shears throw material, the newly added outer protective plate provides a much larger protective area. Furthermore, the added outer protective plate is fully connected and secured to the original blade holder via lower connectors, side connectors, and upper connectors, preventing the outer protective plate from detaching from the blade holder due to branch impacts during trimming.

[0026] See Figure 1 and Figure 2 This embodiment provides a splash-proof device for hedge trimming, including a blade holder 6 and an outer protective plate 1 fixedly connected to one end. Figure 4 This is an assembly structure diagram of the outer protective plate 1 before it is connected to the tool holder 6. It can be made into a semi-finished product in advance for use with similar existing products. Figure 5 The tool holder 6 shown has been modified and upgraded.
[0027] See Figure 5The bottom surface of the tool holder 6 targeted by this utility model is higher than the bottom side surface, and the upper length is shorter than the lower length.
[0028] See Figure 4 The main body 11 of the outer protective plate 1 is an L-shaped bent plate extending perpendicular to the length of the tool holder 6, and its length is greater than the length of the trimmer at the lower end of the tool holder 6. It includes a horizontal part and a vertical part. The horizontal part is flush with the upper end of the tool holder 6, and the vertical part is vertically set on the outer side of the end of the tool holder 6, with its bottom end lower than the bottom surface of the trimmer at the lower end of the tool holder 6. A bent edge is provided on the outer ring of the main body 11 to improve the overall strength.
[0029] The following is combined Figure 2 The lower end of the vertical part of the outer protective plate 1 is fixedly connected to the bottom surface of the tool holder 6 by a lower connecting member 2. The lower connecting member 2 includes two L-shaped frames 21 and a horizontal frame 22. The two L-shaped frames 21 are located on both sides of the lower end of the tool holder 6 and are fixedly connected to the lower end surface and the inner side of the vertical part of the tool holder 6, respectively.
[0030] Specifically, the L-shaped frame 21 is placed upside down. Each L-shaped frame 21 is formed by welding two rectangular tubes perpendicularly together, which reduces the counterweight. The bottom end does not exceed the bottom end of the vertical part of the outer protective plate 1. Preferably, the bottom end of the L-shaped frame 21 is aligned with the lower bent edge of the main body 11 to facilitate welding and improve the overall strength.
[0031] The crossbar 22 also uses rectangular tubing to reduce weight, and it is connected between the corners of the two L-shaped frames 21. Its two sides are welded and fixed to the bottom surface of the tool holder 6 and the inner surface of the outer protective plate 1, respectively. This design improves the strength of the lower connector 2 and seals the gap between the bottom surface of the tool holder 6 and the vertical part of the outer protective plate 1.
[0032] As a further improvement, the area directly opposite the vertical part of the outer protective plate 1 and the tool holder 6 is not only the main stress area for splintering branches, but also requires multiple welding points when connecting to the tool holder 6. Therefore, a reinforcing plate 5 is also provided between the lower connecting piece 2 and the vertical part of the outer protective plate 1. The height of the reinforcing plate 5 is the same as that of the vertical part, and the width is the same as the width of the tool holder 6. This is to improve the strength of the middle part of the outer protective plate 1.
[0033] In this embodiment, two side connecting plates 4 are also fixed in the middle of the inner side of the outer protective plate 1, and the outer ends of the two side connecting plates 4 are fixedly connected to the side of the tool holder 6.
[0034] Specifically, the distance between the two side connecting plates 4 is the same as the width of the tool holder 6. Each side connecting plate 4 is a right-angled triangle, with its two right-angled sides welded to the horizontal and vertical parts of the outer protective plate 1, respectively, and its hypotenuse welded to the side of the tool holder 6.
[0035] The side connecting plate 4 can improve the connection strength between the outer protective plate 1 and the tool holder 6, and can also effectively close the misaligned gaps at both ends of the tool holder 6 to prevent branches from blocking the gaps.
[0036] Regarding the design of the outer bend edge of the main body 11, in this embodiment, the outer protective plate 1 has a 90-degree upward bend 12 at the end of the horizontal portion, a downward bend 14 with a 90-degree inward bend at the end of the vertical portion, and side bends 13 with vertical inward bends on both sides. See [reference needed]. Figure 4 As shown. The design of the flanged edges on all four sides of the outer protective plate 1 can further improve the strength of the main body 11 of the outer protective plate 1, and can effectively resist the impact of flying branches.
[0037] Based on usage experience, although the outer protective plate 1 of this utility model is longer than that of the prior art and has a larger shielding space, the two sides sometimes have the problem of warping. Therefore, a reinforcing member, such as a steel bar, is fixed to the inner root of the side flange 13 to better resist impact deformation.
[0038] In this embodiment, an upper connector 3 is fixed to the horizontal end of the outer protective plate 1, and the upper connector 3 is fixedly connected to the upper surface of the tool holder 6.
[0039] Furthermore, the upper connector 3 can be a rectangular tube with the same length as the outer protective plate 1, one side of which is spot-welded to the outer side of the upper flange 12, and the bottom surface is welded to the upper end face of the tool holder 6.
[0040] Through the above design, the top surface of the tool holder 6 is tightly fitted with the horizontal part of the outer protective plate 1, the side is tightly fitted with the side connecting plate 4, and the bottom surface is tightly fitted with the lower connecting piece 2, thus achieving a seamless connection between the tool holder 6 and the outer protective plate 1, which can effectively prevent branch fragments from remaining at the junction of the two.
[0041] By welding the outer protective plate 1 to one end of the blade holder 6, a strong protection is formed at the front and top of the trimmer, which can effectively prevent the cut branches from flying forward or upward, thus improving the performance of the early hedge trimmer.
[0042] Moreover, compared to the current hedge trimmers, which, in order to save costs, only have a protective plate integrally formed with the blade holder 6 and of the same width, without covering the material throwing range of the trimmer shears, the newly added outer protective plate 1 has a larger protective area. The newly added outer protective plate 1 is fully connected and fixed to the original blade holder 6 through the lower connecting piece 2, the side connecting plate 4, and the upper connecting piece 3, preventing the outer protective plate 1 from being detached from the blade holder 6 due to the impact of branches during the trimming process.
[0043] In addition, this utility model also provides a vehicle-mounted hedge trimmer, the end of which is connected to the aforementioned anti-splash device for hedge trimming.
