Description

Technical Field

[0001] This utility model relates to the field of spraying devices, and in particular to a high-pressure atomizing precision spraying device for forestry. Background Technology

[0002] In forestry pest and disease control and seedling cultivation, high-pressure atomization spraying technology has become the mainstream application method due to its advantages of good atomization effect, uniform coverage, and high pesticide utilization rate. High-pressure atomization forestry spraying devices use a high-pressure container to provide power, pressurizing the pesticide solution and then converting it into fine droplets through atomizing nozzles. This allows the pesticide to adhere more evenly to the branches, trunks, and leaves of trees, improving pest and disease control effectiveness and reducing pesticide waste. Compared to traditional manual spraying and low-pressure spraying methods, it significantly improves both operational efficiency and application quality. Currently, most high-pressure atomization forestry spraying devices on the market consist of a high-pressure storage component, transmission pipeline, atomizing nozzles, and a mobile carrier, adaptable to complex operating environments such as mountainous and forested areas, and meeting the needs of large-scale forestry operations.

[0003] Precise control of the spraying range is a key technical requirement in forestry spraying operations, and its importance is reflected in several aspects. From an ecological protection perspective, forestry areas often contain diverse flora and fauna communities. If the spraying range is out of control, the pesticide solution can easily spread to non-target areas, polluting beneficial organisms, the soil environment, and surrounding water bodies, thus disrupting the ecological balance. From the perspective of control effectiveness, different tree species, growth stages, and the range of pest and disease occurrence vary. Precise control of the spraying range ensures that the pesticide acts concentrated on the target area, avoiding insufficient efficacy due to diffusion, and reducing the development of pesticide resistance in pests and diseases. Therefore, the development of high-pressure atomizing forestry spraying devices with precise spraying range control capabilities has become an important requirement for improving forestry management and promoting the development of green forestry. Utility Model Content

[0004] The main purpose of this invention is to provide a high-pressure atomization precision spraying device for forestry, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-pressure atomizing precision spraying device for forestry includes a high-pressure container. A spray pipe is fixedly connected to the high-pressure container via a connecting hose. An atomizing nozzle is fixedly installed at the front end of the spray pipe. An adjustable spraying assembly is movably installed on the spray pipe and outside the atomizing nozzle. The adjustable spraying assembly consists of an externally threaded tube, a support plate, and a tapered tube. Two support plates are symmetrically fixedly installed inside the externally threaded tube. The tapered tube is fixedly installed at the front end of the externally threaded tube. A fixing assembly is installed on the externally threaded tube. The fixing assembly consists of an arc-shaped plate, a trapezoidal contact block, a return spring, an internally threaded tube, a connecting plate, and a compression tube.

[0006] Preferably, two of each of the arc-shaped plate, trapezoidal contact block, and return spring are provided. The two arc-shaped plates are symmetrically and movably installed inside the external threaded tube. The two arc-shaped plates are simultaneously and movably sleeved on the two support plates. The two trapezoidal contact blocks are respectively fixedly installed at the rear ends of the two arc-shaped plates. The two return springs are respectively fixedly installed inside the two arc-shaped plates, and the return springs are located inside the support plates. The internal threaded tube is threadedly fitted onto the external threaded tube. The connecting plate is fixedly installed at the front end of the internal threaded tube. The extrusion tube is fixedly installed at the front end of the connecting plate. The extrusion tube is simultaneously and movably sleeved on the outside of the two arc-shaped plates and the two trapezoidal contact blocks.

[0007] Preferably, the high-pressure container is fixedly mounted on the trolley bracket, and the connecting hose is fixedly connected to both the high-pressure container and the nozzle.

[0008] Preferably, the external threaded tube on the adjustable beam assembly is movably sleeved on the nozzle, and two receiving grooves are symmetrically opened on the external threaded tube. The support plate is fixedly installed in the receiving groove, and the receiving groove passes through the external threaded tube inside and out. The diameter of the front end of the tapered tube is larger than the diameter of its rear end, and the tapered tube is movably sleeved on the outside of the nozzle and the atomizing nozzle.

[0009] Preferably, the arc-shaped plate and trapezoidal contact block on the fixing component are movably installed in the receiving groove, and the arc-shaped plate is provided with an installation groove, and the arc-shaped plate is movably sleeved on the support plate through the installation groove.

[0010] Preferably, the internally threaded tube on the fixing assembly is located behind the receiving groove, and the arc-shaped plate and trapezoidal contact block are located outside the receiving groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By installing an adjustable pesticide spraying assembly consisting of an externally threaded tube, a support plate, and a conical tube around the atomizing nozzle of the spray pipe, the conical tube can constrain and guide the atomized pesticide solution. By adjusting the forward and backward position of the externally threaded tube on the spray pipe, the relative position of the conical tube and the atomizing nozzle is changed, thereby achieving precise adjustment of the pesticide spraying range. When it is necessary to narrow the spraying range, the conical tube is moved forward, and the pesticide solution is concentrated under the converging effect of the conical tube. When it is necessary to expand the spraying range, the conical tube is moved backward, increasing the pesticide diffusion space. This meets the application needs of different tree spacing and pest and disease occurrence areas, effectively preventing the pesticide solution from spreading to non-target areas. Through adjustable... The powder-coating assembly is equipped with a fixing component consisting of an arc-shaped plate, a trapezoidal contact block, a return spring, an internally threaded tube, a connecting plate, and a squeezing tube. Rotating the internally threaded tube causes the connecting plate and the squeezing tube to move axially along the externally threaded tube. When the squeezing tube moves forward, it squeezes the trapezoidal contact block, causing the two arc-shaped plates to overcome the elastic force of the return spring and contract inward, tightly adhering to the outer wall of the nozzle, thus fixing the position of the adjustable powder-coating assembly. When the internally threaded tube is rotated in the opposite direction, the squeezing tube moves backward, and the arc-shaped plates reset and release the nozzle under the action of the return spring. This allows for convenient and quick adjustment and fixing of the position of the adjustable powder-coating assembly, ensuring stable powder-coating effect during spraying and improving application accuracy and operational reliability.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1-6As shown, a high-pressure atomizing precision spraying device for forestry includes a high-pressure container 1. A spray pipe 2 is fixedly connected to the high-pressure container 1 via a connecting hose 6. An atomizing nozzle 7 is fixedly installed at the front end of the spray pipe 2. An adjustable spraying assembly 3 is movably installed on the spray pipe 2 and outside the atomizing nozzle 7. The adjustable spraying assembly 3 consists of an externally threaded pipe 8, a support plate 10, and a tapered pipe 11. Two support plates 10 are symmetrically fixedly installed inside the externally threaded pipe 8. The tapered pipe 11 is fixedly installed at the front end of the externally threaded pipe 8. A fixing assembly 4 is installed on the externally threaded pipe 8. The fixing assembly 4 consists of an arc-shaped plate 12, a trapezoidal contact block 13, a return spring 15, an internally threaded pipe 16, a connecting plate 17, and a compression pipe 18. The arc-shaped plate 12, the trapezoidal contact block 16, the internally threaded pipe 17, the internally threaded pipe 18, the internally threaded pipe 19, the internally threaded pipe 10, the internally threaded pipe 11, the internally threaded pipe 12, the internally threaded pipe 16, the internally threaded pipe 17, and the internally threaded pipe 18. 3. Two return springs 15 are provided. Two arc-shaped plates 12 are symmetrically and movably installed inside the externally threaded tube 8. The two arc-shaped plates 12 are simultaneously and movably sleeved on the two support plates 10. Two trapezoidal contact blocks 13 are respectively fixedly installed at the rear ends of the two arc-shaped plates 12. The two return springs 15 are respectively fixedly installed inside the two arc-shaped plates 12, and the return springs 15 are located inside the support plates 10. The internally threaded tube 16 is threadedly fitted onto the externally threaded tube 8. The connecting plate 17 is fixedly installed at the front end of the internally threaded tube 16. The extrusion tube 18 is fixedly installed at the front end of the connecting plate 17. The extrusion tube 18 is simultaneously and movably sleeved on the outside of the two arc-shaped plates 12 and the two trapezoidal contact blocks 13. The externally threaded tube 15 is used to complete the process. The adjustable spraying assembly 3, composed of the threaded tube 8, support plate 10, and tapered tube 11, can constrain and guide the atomized pesticide using the tapered tube 11. By adjusting the front and rear positions of the threaded tube 8 on the nozzle 2, the relative position of the tapered tube 11 and the atomizing nozzle 7 can be changed, thereby achieving precise adjustment of the spraying range. When it is necessary to narrow the spraying range, the tapered tube 11 is moved forward, and the pesticide is concentrated and sprayed under the converging effect of the tapered tube 11. When it is necessary to expand the spraying range, the tapered tube 11 is moved backward, increasing the diffusion space of the pesticide, which meets the application needs of different tree spacing and pest and disease occurrence ranges, and effectively avoids the pesticide from spreading to non-target areas. By setting an arc plate 12 and a trapezoidal contact on the adjustable spraying assembly 3, the spraying range can be further improved. The fixing assembly 4, consisting of block 13, return spring 15, internal threaded tube 16, connecting plate 17, and extrusion tube 18, allows the connecting plate 17 and extrusion tube 18 to move axially along the external threaded tube 8 when the internal threaded tube 16 is rotated. When the extrusion tube 18 moves forward, it will squeeze the trapezoidal contact block 13, causing the two arc plates 12 to overcome the elastic force of the return spring 15 and contract inward and tightly adhere to the outer wall of the nozzle 2, thereby fixing the position of the adjustable drug-bearing assembly 3. When the internal threaded tube 16 is rotated in the opposite direction, the extrusion tube 18 moves backward, and the arc plates 12 reset and release the nozzle 2 under the action of the return spring 15. This allows for convenient and quick adjustment and fixing of the position of the adjustable drug-bearing assembly 3, ensuring stable drug-bearing effect during spraying and improving application accuracy and operational reliability.

[0016] Specifically, the high-pressure container 1 is fixedly installed on the trolley bracket 5. The connecting hose 6 is fixedly connected to both the high-pressure container 1 and the spray pipe 2. In use, the prepared pesticide solution is first injected into the high-pressure container 1 filled with compressed gas and sealed. The entire device is then moved to the forest area to be sprayed by pushing the trolley bracket 5. Then, the spray pipe 2 is held and the spraying angle is adjusted. The valve on the high-pressure container 1 is opened. Under high pressure, the pesticide solution in the high-pressure container 1 is transported to the spray pipe 2 through the connecting hose 6. The solution is then atomized by the atomizing nozzle 7 fixedly installed at the front end of the spray pipe 2 and sprayed out to achieve the spraying operation on the forest.

[0017] Specifically, the threaded tube 8 on the adjustable beam assembly 3 is movably fitted onto the nozzle 2. Two symmetrical receiving grooves 9 are formed on the threaded tube 8. A support plate 10 is fixedly installed within the receiving grooves 9, which pass through the threaded tube 8 both inside and out. The diameter of the front end of the tapered tube 11 is larger than its rear end diameter. The tapered tube 11 is movably fitted onto the outside of the nozzle 2 and the atomizing nozzle 7. The arc-shaped plate 12 and the trapezoidal contact block 13 on the fixing assembly 4 are movably installed within the receiving grooves 9. An installation groove 14 is formed on the arc-shaped plate 12. The arc-shaped plate 12 is movably mounted on the support plate 10 through the mounting groove 14. The internally threaded tube 16 on the fixing component 4 is located behind the receiving groove 9. The arc-shaped plate 12 and the trapezoidal contact block 13 are located outside the receiving groove 9. When adjusting the spray range of the liquid medicine, first rotate the internally threaded tube 16 of the fixing component 4 in the opposite direction, so that the internally threaded tube 16 drives the connecting plate 17 and the extrusion tube 18 to move backward along the externally threaded tube 8 of the adjustable bundle medicine component 3. The extrusion tube 18 releases the extrusion action on the trapezoidal contact block 13 and the arc-shaped plate 12. Under the elastic force of the return spring 15, the two arc-shaped plates 12 of the fixed component 4 are reset to the outside and the spray pipe 2 is released. At this time, the external threaded tube 8 of the adjustable powder assembly 3 can be pushed to move back and forth along the spray pipe 2. The tapered tube 11 at the front end of the external threaded tube 8 moves synchronously. When it is necessary to reduce the spraying range, the tapered tube 11 is moved forward, and the atomized liquid sprayed by the atomizing nozzle 7 is concentrated and sprayed under the constraint and guidance of the tapered tube 11. When it is necessary to expand the spraying range, the tapered tube 11 is moved backward, and the atomized liquid is concentrated and sprayed. The diffusion space of the liquid medicine increases. After adjusting to a suitable spraying range, rotate the internal thread tube 16 in the forward direction. The internal thread tube 16 drives the connecting plate 17 and the extrusion tube 18 to move forward. The extrusion tube 18 extrudes the arc plate 12 and fits it on the outside of the trapezoidal contact block 13. This causes the two arc plates 12 to overcome the elastic force of the return spring 15 and contract inward along the support plate 10 until the arc plates 12 are tightly attached to the outer wall of the spray pipe 2, thus completing the fixation of the position of the adjustable liquid medicine assembly 3. After that, the liquid medicine can continue to be sprayed onto the target area.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
