Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and in particular to a portable and efficient orchard sprayer. Background Art

[0002] There are mainly two types of traditional orchard sprayers, vehicle-mounted sprayers and pipe-dragging sprayers. Vehicle-mounted sprayers are suitable for flat orchards, and pipe-dragging sprayers are suitable for mountain orchards. The terrain of mountain orchards is steep, and crawler tractors cannot drive in, so manual pipe-dragging spraying has to be used. Pipe-dragging sprayers are all composed of high-pressure piston pumps, high-pressure water pipes, nozzles, etc. When spraying, one person sprays the fruit trees with a nozzle, and one person drags the high-pressure medicine pipe. The spraying range of the pressure nozzle is small and the penetration is poor. It is necessary to spray all directions with the nozzle to completely penetrate, so the working efficiency is low. One person can spray 3 to 10 mu of fruit trees a day. The orchard spraying period is high-temperature and high-humidity weather, which is very easy to cause heat stroke and poisoning of workers. The traditional pipe-dragging sprayer has a large labor intensity and a harsh working condition when spraying. Therefore, a highly efficient, portable and safe sprayer is proposed.

[0013] Preferably, a carrying handle is fixedly connected to the blower.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When the present invention is in use, by starting the blower to press high-pressure air flow into the elbow pipe, the spray ejected from the spray head is blown out of the straight pipe. At the same time, while the air flow blows out the spray from the casing at a high speed, according to Bernoulli's principle, a vacuum is formed at the inlet of the casing because the surrounding air is carried away by the jet flow, so that the surrounding air enters the casing, driving the surrounding air to flow 6 to 10 times, increasing the air circulation, and forming a confluence with the spray at the outlet of the casing, thereby improving the diffusion effect of the spray. At the same time, through the setting of the inclined plate, the spiral turbulent flow of the air flow can be maintained, accelerating the movement of the spray, so that the spray can be pushed farther by the air flow; when the aerosol flow hits the fruit tree, a large number of vortex turbulent flows will be formed, and the vortex turbulent flows carry the droplets to adhere to all surfaces of the fruit tree, with strong penetration and wide range.

[0016] 2. By setting a conductive metal mesh, the spray passes through an electrostatic field and attaches the same-sex charges. The repulsion of the same-sex charges will split the droplets into smaller droplets. The average diameter of the droplets is between 10 and 15 microns. The repulsion of the electrostatic field makes the average density of the spray less than the air density, so as to form an aerosol by getting rid of the influence of gravity; at this time, the droplets are only affected by the wind force and the electrostatic field force. The wind force can easily bring the droplets into the middle of the canopy of the fruit tree, and the electrostatic field force will adsorb the droplets to the front and back sides of the fruit tree leaves, making the fruit tree leaves evenly covered with medicine.

[0017] 3. By setting an air supply mechanism with a filter, clean air can be provided to the protective mask and can be connected to the protective clothing for ventilation, accelerating the evaporation of sweat inside the protective clothing and improving the comfort of work.

[0018] 4. Through the above settings, the spraying efficiency of mountain orchards can be greatly improved, and a safe and comfortable working environment can be provided for the pesticide applicators, greatly reducing the risk of heatstroke and poisoning of the pesticide applicators.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7 , the present invention provides a technical solution:

[0029] A portable and efficient orchard sprayer, comprising: an air flow propulsion mechanism, a gas supply mechanism, and an electrostatic mechanism.

[0030] As shown in Figure 1 , Figure 2 and Figure 7As shown in the figure, the composition of the air flow propulsion mechanism: The air flow propulsion mechanism includes a connecting plate 1. A blower 6 is installed outside the connecting plate 1, and a storage battery 7 is installed outside the connecting plate 1. The air outlet of the blower 6 is communicated with a bent pipe 8. One end of the bent pipe 8 is communicated with a corrugated hose 9. One end of the corrugated hose 9 is communicated with a straight pipe 10. A plurality of connecting columns 17 are fixedly connected to the outside of the straight pipe 10. A sleeve 12 is fixedly connected to the outside of the connecting column 17. An air multiplier outer shell 33 is fixedly connected to the inside of the straight pipe 10. A plurality of inclined plates 35 are fixedly connected to the outside of the air multiplier outer shell 33. An air multiplier inner shell 36 is fixedly connected to the outside of the inclined plate 35. A handle 32 is fixedly connected to the outside of the sleeve 12. A spraying mechanism is installed inside the straight pipe 10, and an air flow shunting mechanism is installed inside the straight pipe 10.

[0031] As Figure 1 , Figure 2 and Figure 7 shown in the figure, the principle of the air flow propulsion mechanism: Start the blower 6 to introduce air flow into the bent pipe 8. The air flow enters the straight pipe 10 through the corrugated hose 9. The air in the straight pipe 10 forms a spiral flowing air flow through the air flow shunting mechanism. When the air flow enters the air flow component composed of the air multiplier outer shell 33 and the air multiplier inner shell 36, since the air flow enters in a spiral oblique direction, the air flow first rotates and circulates in the air multiplier inner shell 36. The air flow changes direction and rotates along the wall in the air multiplier inner shell 36. At the same time, the space becomes smaller, so that the flow rate of the air flow increases. After the air flow circulates in the air multiplier inner shell 36, it enters the C-shaped air outlet area composed of the air multiplier outer shell 33 and the air multiplier inner shell 36. The space through which the air flow circulates gradually becomes narrower from wide, forming a gas jet. The air flow blows the spray ejected from the spray head 19 out of the straight pipe 10. At the same time, when the high-speed air flow blows the spray out of the sleeve 12, a pressure drop is generated by the high-speed fluid. A vacuum is formed at the inlet of the sleeve 12 because the surrounding air is carried away by the jet, so that the surrounding air enters the sleeve 12, driving the surrounding air to flow 6 to 10 times, increasing the air circulation volume, and forming a confluence with the spray at the outlet of the sleeve 12, thereby improving the diffusion effect of the spray. At the same time, the spiral turbulent flow of the air flow can be maintained through the setting of the inclined plate 35, accelerating the movement of the spray. The handle 32 can be used to control the orientation of the sleeve 12 and the straight pipe 10.

[0032] As Figure 1 , Figure 5 and Figure 7As shown in the figure, the composition of the air supply mechanism: The air supply mechanism includes a housing 24, the housing 24 is fixedly connected to the outside of the blower 6, a connecting hose 23 is connected to the outside of the housing 24, an air filter 31 is fixedly connected inside the housing 24, the connecting hose 23 communicates with the inside of the elbow pipe 8, a first connecting pipe 25 is connected to the outside of the housing 24, one end of the first connecting pipe 25 communicates with a first air valve 26, one end of the first air valve 26 communicates with a second ventilation hose 29, a second connecting pipe 27 is connected to the outside of the housing 24, one end of the second connecting pipe 27 communicates with a second air valve 28, one end of the second air valve 28 communicates with a first ventilation hose 3, one end of the first ventilation hose 3 communicates with a gas mask 4, and third air valves 37 are installed on the outside of both the first ventilation hose 3 and the second ventilation hose 29.

[0033] As Figure 1 , Figure 5 and Figure 7 shown in the figure, the principle of the air supply mechanism: A part of the air flow in the elbow pipe 8 enters the connecting hose 23. An air filter 31 is fixedly connected inside the housing 24. Then it enters the housing 24 through the connecting hose 23, is purified by the air filter 31 and then enters the first connecting pipe 25 and the second connecting pipe 27. When the second ventilation hose 29 is connected to the protective clothing, the air supply to the protective clothing is adjusted by adjusting the air flow rate of the first air valve 26, so that the sweat of the person wearing the protective clothing can be quickly discharged. By adjusting the second air valve 28, the air supply amount of the first ventilation hose 3 to the gas mask 4 can be adjusted to avoid insufficient intake of breathing air in the gas mask 4.

[0034] As Figure 1 and Figure 6 shown in the figure, the composition of the static electricity mechanism: The static electricity mechanism includes a rubber ring 18, the rubber ring 18 is fixedly connected inside the sleeve 12, a conductive metal mesh 13 is fixedly connected to the outside of the rubber ring 18, a rubber power cord 22 is electrically connected to the outside of the storage battery 7, one end of the rubber power cord 22 is electrically connected to a switch 30, the switch 30 is fixedly connected inside the sleeve 12, and the electrical output end of the switch 30 is electrically connected to a voltage multiplier 20, and the electrode needle of the voltage multiplier 20 is electrically connected to the conductive metal mesh 13.

[0035] As Figure 1 and Figure 6As shown in the figure, the principle of the electrostatic mechanism: By setting the conductive metal mesh 13 connected to the voltage multiplier 20, pressing the switch 30 enables the storage battery 7 to supply direct current to the voltage multiplier 20 to energize it, forming an electrostatic field at the outlet of the straight pipe 10. After the spray ejected by the spray head 19 is blown out by the air flow blown out by the straight pipe 10, the spray passes through the electrostatic field and attaches to the same-sex charges. The repulsion between the same-sex charges will keep the distance between the sprays, avoiding the droplets from converging into fog beads when the spray concentration is high and affecting the spray effect. Thus, the discharged spray is more delicate and the distance it is propelled is relatively far. The rubber ring 18 plays an insulating role for the sleeve 12.

[0036] As Figures 1-3 As shown in the figure, the composition of the spray mechanism: The spray mechanism includes a liquid inlet joint 11, the liquid inlet joint 11 is fixedly connected to the outside of the straight pipe 10 and penetrates the inner wall of the straight pipe 10. One end of the liquid inlet joint 11 is fixedly connected with an L-shaped pipe 16. One end of the L-shaped pipe 16 penetrates the outer wall of the air multiplier inner shell 36. One end of the L-shaped pipe 16 is threadedly connected with a spray head 19. The other end of the liquid inlet joint 11 is threadedly connected with a liquid medicine drag pipe 34.

[0037] As Figures 1-3 As shown in the figure, the principle of the spray mechanism: By setting the liquid inlet joint 11, it can be conveniently connected to the high-pressure medicine pipe in the orchard. The spray head 19 can be replaced after closing the conductive metal mesh 13 and the blower 6, which is convenient to use. The liquid medicine drag pipe 34 is used to connect the medicine supply pipeline laid in the orchard.

[0038] As Figures 2-4 As shown in the figure, the composition of the air flow shunting mechanism: The air flow shunting mechanism includes an annular plate 14, the annular plate 14 is fixedly connected to the inside of the straight pipe 10, and a plurality of inclined fan blades 15 are fixedly connected to the inside of the annular plate 14.

[0039] As Figures 2-4 As shown in the figure, the principle of the air flow shunting mechanism: After the air flow enters the straight pipe 10, it blows towards the inclined fan blades 15 and changes the flow direction, forming a spiral turbulent flow, which can effectively reduce the air resistance and enable the spray to be propelled farther by the air flow and speed up at the same time.

[0040] To prevent the rubber power cord 22 from shaking, a fixing block 21 is fixedly connected to the outside of the straight pipe 10, and the fixing block 21 is slidably connected to the rubber power cord 22.

[0041] To facilitate carrying on the back, a shoulder strap 2 is fixedly connected to the outside of the connecting plate 1.

[0042] To facilitate moving the present invention, a handle 5 is fixedly connected to the blower 6.

[0043] Summarize and sort out the working steps of this solution according to the above technical solution: Start the blower 6 to introduce air flow into the elbow 8. The air flow enters the straight pipe 10 through the corrugated hose 9. After the air flow enters the straight pipe 10, it blows towards the inclined fan blades 15 to change the flow direction, forming a spiral turbulent flow, which can effectively reduce the air resistance, so that the spray can be pushed farther by the air flow and the speed is increased at the same time. When the air flow enters the air flow component composed of the air multiplier outer shell 33 and the air multiplier inner shell 36, since the air flow enters in a spiral oblique direction, the air flow first rotates and circulates in the air multiplier inner shell 36. Due to the change of direction and the wall-attached rotation of the air flow in the air multiplier inner shell 36, and at the same time the space becomes smaller, the flow rate of the air flow increases. After the air flow circulates in the air multiplier inner shell 36, it enters the C-shaped air outlet area composed of the air multiplier outer shell 33 and the air multiplier inner shell 36. The space where the air flow circulates gradually changes from wide to narrow, forming a gas jet. The air flow blows the spray ejected from the spray head 19 out of the straight pipe 10. At the same time, when the high-speed air flow blows the spray out of the sleeve 12, a pressure drop is generated by the high-speed fluid. A vacuum is formed at the inlet of the sleeve 12 because the surrounding air is carried away by the jet, so that the surrounding air enters the sleeve 12, driving the surrounding 6-10 times of air flow, increasing the air circulation volume, and forming a confluence with the spray at the outlet of the sleeve 12, thereby improving the diffusion effect of the spray. At the same time, the spiral turbulent flow of the air flow can be maintained through the setting of the inclined plate 35, accelerating the movement of the spray. The handle 32 can be used to control the orientation of the sleeve 12 and the straight pipe 10. Part of the air flow in the elbow 8 enters the connecting hose 23. An air filter 31 is fixedly connected inside the housing 24, then enters the housing 24 through the connecting hose 23, and enters the first connecting pipe 25 and the second connecting pipe 27 after being purified by the air filter 31. When the second ventilation hose 29 is connected to the protective clothing, the protective clothing is supplied with air by adjusting the air flow rate of the first air valve 26, so that the sweat of the person wearing the protective clothing can be quickly discharged. By adjusting the second air valve 28, the air supply amount to the gas mask 4 by the first ventilation hose 3 can be adjusted to avoid insufficient breathing air intake in the gas mask 4. By setting the conductive metal mesh 13 connected to the voltage multiplier 20, pressing the switch 30 makes the storage battery 7 supply direct current to the voltage multiplier 20 to be energized, and an electrostatic field is formed at the outlet of the straight pipe 10. After the spray ejected from the spray head 19 is blown out by the air flow ejected from the straight pipe 10, the spray passes through the electrostatic field and attaches to the same-sex charge. The repulsion of the same-sex charges will keep the distance between the sprays, avoiding the droplets formed by the convergence of the sprays when the spray concentration is high and affecting the spray effect, so that the discharged spray is more delicate and the pushed distance is relatively far. The rubber ring 18 plays an insulating role for the sleeve 12. By setting the liquid inlet joint 11, it can be conveniently connected to the high-pressure medicine pipe in the orchard. The spray head 19 can be replaced after closing the conductive metal mesh 13 and the blower 6, which is convenient to use. The liquid medicine drag pipe 34 is used to connect the medicine supply pipeline laid in the orchard.

[0044] In summary, when the present invention is in use, the blower 6 is started to introduce air flow into the elbow 8, and the spray ejected from the spray head 19 is blown out of the straight pipe 10. At the same time, while the air flow blows out the spray from the housing 12 at high speed, a vacuum is formed at the inlet of the housing 12 because the surrounding air is carried away by the jet flow, so that the surrounding air enters the housing 12, driving the flow of air around it by 6 to 10 times, increasing the air circulation, and forming a confluence with the spray at the outlet of the housing 12, thereby improving the diffusion effect of the spray. At the same time, the spiral turbulent flow of the air flow can be maintained through the setting of the inclined plate 35, accelerating the movement of the spray, so that the spray can be pushed farther by the air flow. By setting the conductive metal mesh 13, the spray passes through the electrostatic field and attaches the same-sex charges. The repulsion of the same-sex charges will keep the distance between the sprays, avoiding the influence of the spray effect caused by the aggregation of the sprays into droplets when the spray concentration is high. Therefore, the discharged spray is more delicate and can be pushed to a relatively far distance, reaching the back of the leaves. The spray head 19 can be quickly replaced according to the particle size requirements of different sprays, and it can be conveniently carried to the orchards in the mountains or forests, solving the problem that the wheeled sprayer is not convenient to enter. By achieving a long-distance spraying effect, the range of the sprayed medicament is wider, thereby improving the work efficiency of the user, and it is more time-saving and labor-saving compared with the traditional spraying method. By setting the air supply mechanism, sufficient air can be provided to the gas mask 4 and can be connected to the protective clothing for ventilation, accelerating the evaporation of sweat from the protective clothing and improving the comfort of the work.
