Description

Technical Field

[0001] This utility model relates to the technical field of spray paint water retention tools, specifically a portable and uniform spray paint water retention tool for shrub coppicing. Background Technology

[0002] Shrub coppicing is an important tending and regeneration measure in forestry management, ecological restoration, and desertification control. By cutting off the above-ground stems of shrubs, it can effectively promote sprouting and regeneration, rejuvenate plants, and regulate community structure. However, the exposed stubble surface after coppicing loses its original epidermal protection. Under drought, strong sunlight, and strong winds, moisture is rapidly lost through the xylem vessels, and the exposed phloem and cambium are also susceptible to pests, diseases, and cracking, severely affecting sprouting survival rate and subsequent growth. To reduce moisture evaporation from the stubble, seal wounds, and prevent pathogen invasion, specialized water-retaining agents, healing agents, or film-forming coatings are often used in production for spraying and sealing the stubble.

[0003] Currently, stubble coating operations mostly rely on traditional handheld spray guns or ordinary brushes. These methods have significant shortcomings in practical applications: First, it's difficult to maintain a stable distance and angle between the nozzle and the stubble, especially in windy conditions outdoors. Airflow easily interferes with the paint mist trajectory, leading to uneven paint coverage, missed areas, or localized buildup, severely impacting the sealing effect. Second, the operator needs to hold the spray gun in one hand and use the other to help stabilize the shrub branches, making it difficult to ensure the nozzle remains perpendicular and at a constant distance from the rotating curved stubble surface, resulting in low painting efficiency and high labor intensity. Third, the stem thickness varies significantly between different shrub species or even different plants within the same species. Existing nozzles have a fixed diameter and cannot adapt to stubble diameters, easily causing paint scattering, waste, and environmental pollution. Therefore, improvements to existing technologies are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a portable and uniform spray painting tool for retaining moisture on shrub coppicing, which solves the problems of poor spray uniformity and the inconvenience of traditional equipment being too large to carry.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable and uniform spray painting tool for retaining moisture at the stubble edge of shrubs, comprising a spray gun, a pressure stabilizing valve fixedly installed at the left end of the spray gun, a storage tank threadedly installed at the lower end of the pressure stabilizing valve, a circular cover threadedly connected to the left end of the pressure stabilizing valve, a windproof mechanism provided inside the circular cover, a spray nozzle fixedly installed inside the left end of the pressure stabilizing valve, a semi-ring fixing frame fixedly installed at the left end of the circular cover, a semi-ring frame rotatably connected inside the semi-ring fixing frame, a double-rod frame slidably connected inside the upper end of the semi-ring fixing frame, a support plate fixedly installed at the lower end of the double-rod frame, a pawl strip fixedly installed at the lower ends of the two rods of the support plate, and springs provided on the outer sides of the two rods of the double-rod frame.

[0006] Preferably, a switch button is installed on the outside of the paint gun, and a battery interface is fixedly installed at the lower end of the paint gun, so that the paint gun can be connected to an external lithium battery, making the device more portable.

[0007] Preferably, the outer diameter of the semi-ring frame is the same as the inner diameter of the semi-ring fixing frame, the support plate is slidably connected to the semi-ring fixing frame, and the semi-ring frame can slide into the interior of the semi-ring fixing frame.

[0008] Preferably, one end of the spring is fixedly connected to the semi-ring fixing frame, and the other end of the spring is fixedly connected to the support plate. The spring can support the support plate through its elastic force.

[0009] Preferably, the upper end of the double-bar frame is provided with a lifting ring, and the pawl is slidably connected to the semi-ring fixing frame, so that the double-bar frame can be moved by the lifting ring.

[0010] Preferably, the semi-ring frame has multiple arc-shaped grooves on its arc surface, and the pawl strip engages with the grooves, allowing the pawl strip to limit the semi-ring frame's position through the grooves.

[0011] Preferably, the windproof mechanism includes an elastic cover, the inside of which is bonded to the circular cover, and a highly elastic ring is installed inside the elastic cover at the opening. The elastic cover is movably connected to the nozzle, and the highly elastic ring can wrap around the branches.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a unique "semi-ring fixing bracket - semi-ring bracket - pawl" mechanical locking mechanism to quickly and securely lock the spray head onto the cut surface, achieving relative stillness between the spray head and the cut surface during spraying. This fundamentally eliminates the impact of manual handling and shaking. Simultaneously, the elastic windproof shield integrated around the spray head adapts to the cut surface's thickness and forms a protective envelope, effectively isolating external airflow interference and creating a stable microenvironment. The combination of these two features ensures that the paint mist vertically, evenly, and completely covers the cut surface, forming a high-quality protective film, thereby greatly improving the actual effects of water retention, sealing, and wound healing.

[0014] 2. This utility model integrates material storage, pressure stabilization, spraying, and wrapping / locking functions into a single-handedly held body through an integrated structure, significantly simplifying the work process. Its self-adaptive locking mechanism can quickly fit and lock stubble of different diameters, achieving convenient operation of "one set, one press to lock, one press to spray," significantly reducing the technical threshold and labor intensity for operators. At the same time, the windproof wrapping design effectively reduces paint scattering, saving materials and reducing environmental pollution. The tool has a compact structure, is durable and reliable, and is very suitable for mobile field operations. A single person can efficiently complete the work, achieving a simultaneous improvement in portability, versatility, and work efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 A portable, uniform spray painting tool for retaining moisture at the stubble edge of shrubs includes a spray gun 1. A pressure stabilizing valve 2 is fixedly installed at the left end of the spray gun 1. A storage tank 3 is threadedly installed at the lower end of the pressure stabilizing valve 2. A circular cover 4 is threadedly connected to the left end of the pressure stabilizing valve 2. A windproof mechanism 5 is provided inside the circular cover 4. A spray nozzle 6 is fixedly installed inside the left end of the pressure stabilizing valve 2. A semi-ring fixing frame 9 is fixedly installed at the left end of the circular cover 4. A semi-ring frame 10 is rotatably connected inside the semi-ring fixing frame 9. A double rod frame 12 is slidably connected inside the upper end of the semi-ring fixing frame 9. A support plate 13 is fixedly installed at the lower end of the double rod frame 12. A pawl strip 14 is fixedly installed at the lower ends of the two rods of the support plate 13. Springs 15 are provided on the outer sides of the two rods of the double rod frame 12.

[0024] Please see Figure 1-6 A switch button 7 is installed on the outside of the paint gun 1. A battery interface 8 is fixedly installed at the lower end of the paint gun 1. The paint gun 1 can be connected to an external lithium battery, making the device more portable. The outer diameter of the semi-ring frame 10 is the same as the inner diameter of the semi-ring fixed frame 9. The support plate 13 is slidably connected to the semi-ring fixed frame 9. The semi-ring frame 10 can slide into the interior of the semi-ring fixed frame 9. One end of the spring 15 is fixedly connected to the semi-ring fixed frame 9, and the other end of the spring 15 is fixedly connected to the support plate 13. The spring 15 can support the support plate 13 through its elasticity. A lifting ring is provided at the upper end of the double rod frame 12. The pawl strip 14 is slidably connected to the semi-ring fixed frame 9. The double rod frame 12 can be moved by the lifting ring. Multiple arc-shaped ratchet grooves 11 are opened on the arc surface of the semi-ring frame 10. The pawl strip 14 is engaged with the ratchet grooves 11. The pawl strip 14 can limit the semi-ring frame 10 through the ratchet grooves 11.

[0025] Please see Figure 1-6The windproof mechanism 5 includes an elastic cover 51. The elastic cover 51 is bonded to the inside of the circular cover 4. A high elastic ring 52 is installed inside the elastic cover 51 and at the opening. The elastic cover 51 is movably connected to the nozzle 6. The high elastic ring 52 can wrap the branches.

[0026] The specific implementation process of this utility model is as follows: The operator holds the handle of the spray gun 1, with his thumb near the switch button 7. By lifting the lifting ring at the upper end of the double rod frame 12, the operator overcomes the elastic force of the spring 15, causing the support plate 13 and the pawl strip 14 fixed below it to move upward, so that they are separated from the ratchet groove 11 on the arc surface of the semi-ring frame 10. At this time, the semi-ring frame 10 can be freely rotated and opened around the connection point with the semi-ring fixing frame 9. The opened semi-ring frame 10 is then inserted into the shrub stubble to be treated from the side. The double rod frame 12 is released, and under the reset action of the spring 15, the support plate 13 drives the pawl strip 14 to press down. The operator then pushes the tool into the stubble, so that the stubble gradually enters the interior of the circular cover 4.

[0027] The stubble first contacts and squeezes the elastic cover 51 of the windproof mechanism 5 and the high elastic ring 52 at its opening, causing it to deform and tightly wrap around the stubble of different diameters, thereby forming a relatively sealed spraying chamber in front of the nozzle 6, effectively isolating external wind force. At the same time, the stubble generates a thrust on the inner side of the semi-ring frame 10, causing it to rotate and close relative to the semi-ring fixing frame 9 until it tightly hugs the stubble. As the semi-ring frame 10 rotates, the ratchet groove 11 on its outer arc surface slides over the downward-pressed pawl strip 14. Under the continuous downward pressure of the spring 15, the pawl strip 14 finally engages in the corresponding ratchet groove 11, achieving mechanical self-locking. Thus, the semi-ring frame 10, the semi-ring fixing frame 9, and the entire front end of the tool are firmly locked on the stubble, and the nozzle 6 and the stubble cross-section maintain a precise relative stationary state.

[0028] After the tool is securely locked onto the stubble, the operator presses switch button 7 to start the paint gun 1. Under pressure, the water-retaining paint in the storage tank 3 is output stably through the pressure stabilizing valve 2 and finally atomized and sprayed out from the nozzle 6 fixed in the center of the circular cover 4. Since the nozzle 6 is directly facing the stubble that has been wrapped by the elastic cover 51, the paint mist is evenly and vertically sprayed onto the stubble cross-section in the sealed chamber.

[0029] After the spraying is completed, release the switch button 7 to stop the spraying. Raise the double rod 12 again to disengage the pawl 14 from the ratchet groove 11, release the lock on the semi-ring frame 10, remove the tool from the stubble, and the semi-ring frame 10 will rotate open under its own structure or slight external force. The elastic cover 51 and the high elastic ring 52 will return to their original state by relying on elasticity, ready for the next operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
