Description

Technical Field

[0001] This utility model relates to the field of tree protection technology, specifically a tree protective layer coating device. Background Technology

[0002] Tree protective coatings are functional protective layers applied to the surface of tree trunks through physical or chemical means, designed to enhance tree resilience and extend their lifespan. Their core functions include resisting pests and diseases, buffering frost damage and sunscald caused by extreme temperature differences, and preventing mechanical damage, while also being aesthetically pleasing and eco-friendly. Suitable for winter protection, protection of newly transplanted trees, pest and disease control in high-incidence areas, and restoration of ancient and famous trees, etc. When using, ensure even application, avoiding pores and wounds, and reapply regularly to maintain effectiveness.

[0003] Patent CN214288969U discloses a rapid application device for a protective layer on fruit trees in winter. The device includes a movable base, a lime slurry cylinder, a lime application mechanism, and a lifting base. The movable base has multiple casters at its bottom and a locking assembly. The lime slurry cylinder is placed on the movable base and fixed thereto. A stirring assembly inside the lime slurry cylinder stirs the lime slurry. A lifting assembly is mounted on the movable base, and a lifting base that moves up and down on the lifting assembly is mounted on the lifting base. The lime application mechanism is located on the lifting base. This device facilitates the rapid application of a protective layer to tree trunks without the need for manual lime application, thus reducing the workload of workers and improving work efficiency.

[0004] While the aforementioned device can quickly apply a protective layer to tree trunks without the need for manual lime application, it still has the following shortcomings: In real life, the diameter of each tree will be different. Although the device mentioned above can adjust the height by raising and lowering, it is not very adaptable to changes in the diameter of the tree trunk. For tree trunks with a diameter smaller than the device's range of applicability, a large gap will be created between the device and the tree trunk, resulting in uneven adhesion of the protective layer, such as missed areas or uneven thickness. On the other hand, tree trunks with a diameter that is too large may be squeezed by the device, and the coating can only cover a local area. It is difficult to reach the folds or protrusions of the bark, leaving the tree exposed to threats such as pests and diseases and extreme temperatures, thus rendering the protective effect ineffective. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tree protective layer coating device that solves the problem of insufficient adhesion to tree trunks of different diameters.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tree protective layer coating device, comprising a soft brush, the soft brush being evenly disposed on the inner side of a soft rubber base plate, the soft rubber base plate being elongated, the outer side of the soft rubber base plate being mounted on a U-shaped elastic steel strip, the U-shaped elastic steel strip being provided with a buckle, the soft rubber base plate having an installation opening for cooperating with the buckle, and rotating handle assemblies being symmetrically disposed at both ends of the outer side of the U-shaped elastic steel strip.

[0007] Furthermore, the rotating handle assembly includes a rotating base fixedly mounted on both ends of the outer side of the U-shaped elastic steel strip. A rotating connecting block is rotatably connected to the top surface of the rotating base. A rotating limiting block is provided at the upper end of the bottom surface of the rotating connecting block. An arc-shaped rotating groove for the rotating limiting block to rotate is opened in the rotating base. The rotation angle of the rotating limiting block in the arc-shaped rotating groove is limited to 180°. A hand-held long rod is provided extending backward from the outer side of the rotating connecting block.

[0008] Furthermore, the handheld long rod is detachable, and a threaded rod is provided at the front end of the handheld long rod, which is threadedly connected and fixed to the rotating connecting block.

[0009] Furthermore, the handheld pole is a telescopic pole, with the front and rear ends of the handheld pole fixedly connected by a threaded rotation.

[0010] Furthermore, an anti-slip pad is provided on the outer rear end of the handheld long pole.

[0011] Furthermore, an indicator strip is provided at the upper end of the outer top surface of the rotating base, which is located on the same projection plane as the rotation limit block.

[0012] Furthermore, the inner side of the U-shaped elastic steel strip is provided with limiting strips that fit against the soft rubber base plate on both the upper and lower sides.

[0013] Furthermore, a soft magnetic patch is provided on the outer side of the soft rubber base plate to fit the inner side of the U-shaped elastic steel strip.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By placing the soft coating brush inside the soft rubber base plate, which can bend to a certain extent according to the shape of the tree trunk, and in conjunction with the elasticity of the U-shaped flexible steel strip, it can better conform to tree trunks of different diameters, making the protective layer more even and improving the coating effect. The rotating handle assembly allows adjustment of the angle between the soft rubber base plate and the U-shaped flexible steel strip, ensuring the soft coating brush remains in close contact with the tree trunk surface. The detachable handheld pole facilitates assembly, disassembly, and transportation, and also allows for easy replacement if damaged. The anti-slip pad prevents the device from shaking due to slippage during operation, ensuring coating accuracy. The indicator strip helps operators quickly locate the rotating connecting block for accurate operation. The limit strip restricts the vertical displacement of the base plate during operation, preventing it from shifting due to coating force. The soft magnetic adhesive pad ensures both stability and quick disassembly of the base plate, balancing stability and maintenance efficiency. Attached Figure Description

[0017] 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.

[0018] like Figures 1 to 4As shown, a tree protective coating device includes a soft coating brush 1, which is evenly disposed on the inner side of a soft rubber base plate 2. The soft rubber base plate 2 is elongated and mounted on a U-shaped elastic steel strip 3 on the outer side. The U-shaped elastic steel strip 3 is provided with a buckle 301. The soft rubber base plate 2 has an installation opening 201 that cooperates with the buckle 301. Rotating handle assemblies 4 are symmetrically arranged at both ends of the outer side of the U-shaped elastic steel strip 3.

[0019] like Figure 1 As shown, the coating device in this utility model is similar in function to existing coating devices. For example, patent CN214288969U discloses a rapid coating device for fruit tree protective layers in winter. The main improvement of this utility model is that it solves the problem of insufficient adhesion to tree trunks of different diameters. Figures 1 to 4 As shown, this utility model discloses a tree protective coating application device. In use, the U-shaped elastic steel strip 3 and the soft rubber base plate 2 are first rotated forward, allowing the soft coating brush 1 to be directly aligned with the coating bucket. This eliminates the need to tilt the long rod or have a person's hand near the bucket opening to apply the coating. After applying the coating, the worker uses the long rod 405 to attach the soft coating brush 1 to the tree. Depending on the tree's diameter, the elasticity of the U-shaped elastic steel strip 3 and the softness of the rubber base plate 2 allow the soft coating brush 1 to completely cover the tree surface, thus better conforming to tree trunks of different diameters and ensuring a more even application of the protective layer. Then, the device is dragged up and down to apply the protective layer to the tree trunk. The operation is simple and quick. When not in use, the soft rubber base plate 2, which is fixed by the buckle 301 and the soft magnetic patch 202, can be quickly removed for easy daily maintenance of the soft coating 1. At the same time, the detachable handheld rod 405 can also be quickly disassembled by the threaded rod 406, which facilitates the assembly, disassembly and transportation of the device, and also makes it easy to replace when the handheld rod 405 is damaged or the anti-slip pad 407 is worn.

[0020] like Figures 1 to 4 As shown, the rotating handle assembly 4 includes a rotating base 401 fixedly disposed at both ends of the outer side of the U-shaped elastic steel strip 3. A rotating connecting block 402 is rotatably connected to the top surface of the rotating base 401. A rotating limiting block 403 is disposed at the upper end of the bottom surface of the rotating connecting block 402. An arc-shaped rotating groove 404 for rotating the rotating limiting block 403 is opened in the rotating base 401. The rotation angle of the rotating limiting block 403 in the arc-shaped rotating groove 404 is limited to 180°. A hand-held long rod 405 is provided extending backward from the outer side of the rotating connecting block 402.

[0021] Specifically, when applying a protective layer to trees, workers use a long handle 405 to rotate the U-shaped flexible steel strip 3 and the soft rubber base 2 forward. At this time, the rotation limit block 403 within the arc-shaped rotation groove 404 rotates, limiting the angle and allowing the soft coating brush 1 to be directly aligned with the coating bucket. This eliminates the need to tilt the handle or bring the hand close to the bucket opening for application, preventing coating from sticking to the handle or the operator's hands, reducing material waste and cleaning burden. When applying coating to tree trunks at different heights or locations, the angle between the long handle 405 and the coating component can be adjusted by rotating the handle assembly 4, resulting in a more natural grip.

[0022] like Figure 4 As shown, the handheld long rod 405 is detachable, and a threaded rod 406 is provided at the front end of the handheld long rod 405. The threaded rod 406 is threadedly connected and fixed to the rotating connecting block 402.

[0023] Specifically, by setting a detachable handheld rod 405, which is fixed to the rotating connecting block 402 by a threaded rod 406, the device is easy to assemble, disassemble and transport, and can also be easily replaced when the handheld rod 405 is damaged or the anti-slip pad 407 is worn.

[0024] like Figure 2 and Figure 4 As shown, the handheld long rod 405 is a telescopic rod, and the front and rear ends of the handheld long rod 405 are fixedly connected by a threaded rotation.

[0025] Specifically, the handheld rod 405 is a telescopic rod, which allows the operator to rotate the rear end of the handheld rod 405 to separate the front and rear ends when facing areas that cannot be directly coated. The rear end of the handheld rod 405 can slide backward and extend, and after reaching the thread on the bottom surface of the front end of the handheld rod 405, it can be tightened to complete the fixation, realizing the telescopic adjustment of the handheld rod 405 and expanding the coating range of the device.

[0026] like Figure 4 As shown, an anti-slip pad 407 is provided on the outer rear end of the handheld long rod 405.

[0027] Specifically, by setting an anti-slip pad 407 on the outer rear end of the handheld long rod 405, the friction between the hand and the long rod can be increased, preventing the device from shaking due to hand slippage during operation and ensuring the accuracy of coating.

[0028] like Figure 4 As shown, an indicator strip 408 is provided at the upper end of the outer top surface of the rotating base 401, which is located on the same projection plane as the rotation limit block 403.

[0029] Specifically, by setting an indicator strip 408 on the outside of the rotating base 401, and the indicator strip 408 and the rotating limit block 403 are located on the same projection plane, the operator can quickly determine the position of the rotating limit block 403, which facilitates accurate operation.

[0030] like Figure 3 and Figure 4 As shown, the inner side of the U-shaped elastic steel strip 3 is provided with limiting strips 302 that fit against the soft rubber base plate 2 on the upper and lower sides.

[0031] Specifically, by setting upper and lower limiting strips 302 on the upper and lower sides of the soft rubber base plate 2, the vertical displacement of the soft rubber base plate 2 during operation can be restricted, and the base plate can be prevented from shifting due to the force of brushing.

[0032] like Figure 3 and Figure 4 As shown, a soft magnetic patch 202 is provided on the outer side of the soft rubber base plate 2 to fit the inner side of the U-shaped elastic steel strip 3.

[0033] Specifically, by setting a soft magnetic patch 202 on the outside of the soft rubber base plate 2 that fits the inside of the U-shaped elastic steel strip 3, the base plate can be quickly disassembled while ensuring its firmness, thus balancing stability and maintenance efficiency.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
