Description

Technical Field

[0001] This invention relates to the field of tree maintenance equipment technology, specifically to a whitewash spraying device for tree maintenance. Background Technology

[0002] Trees have a long growth cycle, during which maintenance measures are required. A common method is to spray a whitening agent, made of white pigments such as titanium dioxide and zinc oxide, onto the surface of the tree trunk. The whitening agent can reflect solar ultraviolet rays and heat radiation, reduce the temperature of the tree, reduce the pressure of light and heat, and form a protective film to reduce water evaporation and loss, thereby improving water use efficiency. In addition, it can protect trees from damage caused by wind, sand, smog, acid rain, etc. In actual spraying operations, the whitening operation is usually completed with the help of spraying equipment to improve work efficiency.

[0003] A prior art patent with publication number CN118142733B discloses a device including a handle with an adjustment component hinged to its end. Both ends of the adjustment component are hinged to semi-circular frames, each containing multiple telescopic components. These telescopic components are equipped with spraying components, which work together to form a complete columnar spraying area. Multiple balancing components are hinged to the bottom of each of the two semi-circular supports. This device maintains a preset fixed distance between the flat nozzle and the tree surface, ensuring that the nozzle does not become too close to the tree surface, thus preventing spraying efficiency issues. The device is relatively small, portable, and easy to operate, making it suitable for spraying operations in large-area agricultural, forestry, and orchard environments. The addition of balancing components at the bottom of the semi-circular frames further enhances the overall stability of the device.

[0004] As these existing technologies, including the aforementioned patents, have been used, their shortcomings have gradually become apparent, mainly in the following aspects: The diameter of the tree trunk gradually increases from top to bottom. During the spraying operation, the nozzle moves radially to adapt to the change in tree diameter. However, the relative distance between the nozzle and the tree trunk surface remains unchanged during this process. Since the relative distance between the object being sprayed (tree trunk) and the nozzle directly determines the spraying area of ​​the nozzle, and the existing equipment keeps this distance constant during use, the actual spraying area of ​​the nozzle is fixed. However, the circumferential area at different heights of the tree trunk changes with the increase or decrease in diameter. Therefore, when spraying a tree trunk with a variable diameter with a fixed spraying area, problems such as incomplete coverage or excessive paint accumulation may occur, which will affect the uniformity of whitewashing and the protective effect.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a whitewash spraying device for tree maintenance. The spraying area of ​​the nozzle of this device can be adaptively adjusted according to the change in tree diameter. When the trunk diameter increases, the spraying area of ​​the nozzle expands, and vice versa, which significantly improves the uniformity of whitewash spraying.

[0007] To address the above problems, the present invention provides the following technical solution: A tree whitewash spraying device includes a handle, one end of which is fixedly fitted with a fixed arc-shaped plate. Movable arc-shaped plates are hinged to both sides of the fixed arc-shaped plate. Several mounting plates are fixedly fitted to the top of the movable arc-shaped plates. A sliding U-shaped frame is provided on the top of each mounting plate, slidingly arranged radially along the movable arc-shaped plates. A pressing wheel is rotatably mounted at the end of the sliding U-shaped frame. A sliding support plate is slidably mounted on the top of the sliding U-shaped frame, and a spray nozzle is mounted on the sliding support plate. When the sliding U-shaped frame slides relative to the mounting plates, a relative sliding in the same direction occurs between the sliding support plate and the sliding U-shaped frame.

[0008] As an optimized solution, the inner wall of the sliding U-shaped frame is provided with two rotating shafts, and the outer wall of the rotating shafts is fixedly fitted with sprockets. The two sprockets are connected by an L-shaped accessory chain, and the L-shaped accessory on the L-shaped accessory chain is fixedly connected to the sliding support plate.

[0009] As an optimized solution, a rack is fixedly provided on the top of the mounting plate, and one end of one of the rotating shafts extends outward through the sliding U-shaped frame and is fixedly fitted with a gear that meshes with the rack.

[0010] As an optimized solution, a fixed cylinder is fixedly provided at the bottom of the mounting plate, and a sliding rod is slidably provided inside the fixed cylinder. One end of the sliding rod passes through the fixed cylinder and extends to the outside and is fixedly connected to the sliding U-shaped frame. A compression spring is provided inside the fixed cylinder, and the two ends of the compression spring abut against the sliding rod and the fixed cylinder respectively.

[0011] As an optimized solution, the fixed arc-shaped plate and the two movable arc-shaped plates form a complete circular structure.

[0012] As an optimized solution, a locking plate is fixedly provided on the outer wall of the movable arc plate, one of the locking plates having a bolt threadedly connected to it at one end, and the other locking plate having a threaded hole at one end.

[0013] As an optimized solution, a heightening plate is fixedly provided on the top of the sliding support plate, and the nozzle is fixedly installed on the heightening plate.

[0014] As an optimized solution, a fixed plate is fixedly provided at the end of the sliding U-shaped frame, and a fixed flow pipe is provided through the end of the fixed plate. One end of the flow pipe is connected to the nozzle, and the other end is connected to the whitening agent storage tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are: When spraying whitewash on trees, the trunk is enclosed in a circular structure consisting of a fixed arc-shaped plate and a movable arc-shaped plate. The two movable arc-shaped plates are locked with bolts. A compression spring keeps the extrusion wheel in contact with the trunk. The whitewash is sprayed onto the trunk surface through the nozzle. The operator moves the device up and down by holding a handle. When the device moves downward, the tree diameter increases, the sliding U-shaped frame slides outward, the compression spring is compressed, and the gears rotate. Driven by the sprocket and the L-shaped accessory chain, a relative sliding occurs between the sliding support plate and the sliding U-shaped frame in the same direction as the sliding U-shaped frame. At this time, the relative distance between the nozzle and the trunk increases, and the spraying area expands. Conversely, when the device moves upward, the spraying area shrinks. The spraying area of ​​the device can adaptively adjust with the change of tree diameter. When the trunk diameter increases, the spraying area expands, and vice versa, significantly improving the uniformity of whitewash application. Attached Figure Description

When the sliding U-shaped frame 8 slides relative to the mounting plate 4, the sliding support plate 12 and the sliding U-shaped frame 8 slide relative to each other in the same direction.

[0021] The inner wall of the sliding U-shaped frame 8 is provided with two rotating shafts 20. The outer wall of the rotating shafts 20 is fixedly fitted with sprockets 21. The two sprockets 21 are connected by an L-shaped accessory chain 22. The L-shaped accessory on the L-shaped accessory chain 22 is fixedly connected to the sliding support plate 12.

[0022] A rack 16 is fixedly mounted on the top of the mounting plate 4, and one end of a rotating shaft 20 extends outward through the sliding U-shaped frame 8 and is fixedly fitted with a gear 15 that meshes with the rack 16.

[0023] The bottom of the mounting plate 4 is fixedly provided with a fixed cylinder 18. A sliding rod 17 is slidably provided inside the fixed cylinder 18. One end of the sliding rod 17 passes through the fixed cylinder 18 and extends to the outside and is fixedly connected to the sliding U-shaped frame 8. A compression spring 19 is provided inside the fixed cylinder 18. The two ends of the compression spring 19 abut against the sliding rod 17 and the fixed cylinder 18 respectively.

[0024] The fixed arc plate 2 and the two movable arc plates 3 form a complete circular structure.
