A spraying device for removing leaf beetles in tea gardens

Abstract

This invention relates to the field of tea garden pest control technology, and more particularly to a spraying device for controlling leaf beetles in tea gardens. The device includes a box and a frame embedded and fixed to the top of the box. A liquid inlet pipe connects to the box, and the top of the frame has evenly spaced openings. A collection frame for collecting the killed leaf beetles is placed inside the frame. The invention first activates a servo motor to rotate the T-shaped spray nozzle forward, then activates a water pump to draw pesticide into the outlet pipe. The pesticide in the outlet pipe is sprayed onto the tea leaves through the T-shaped spray nozzle, thus treating the tea leaves and killing the leaf beetles. Simultaneously, a yellow LED light is activated to attract the leaf beetles. Then, an electric screw is activated to move a conical ring downwards. An arc-shaped cover first seals the fixed frame, and the conical ring then removes the leaf beetles from the yellow LED light and moves them into the collection frame for further killing. This prevents the leaf beetles from feigning death and remaining on the tea leaves to further consume them, thereby improving the pest control effect.

Description

Technical Field

[0001] This invention relates to the field of pest control technology in tea gardens, and more particularly to a spraying device for removing leaf beetles in tea gardens. Background Technology

[0002] During the daily management of tea plants, it is necessary to spray pesticides regularly to remove leaf beetles from the tea leaves and prevent them from damaging the tea and affecting its quality.

[0003] Currently, existing spraying devices are equipped with spray guns, requiring operators to hold the guns and spray the tea leaves to remove leaf beetles. However, when spraying by hand, some pesticide gets on the hands and body, which can easily cause harm. While spraying with a machine eliminates the need for manual spraying, some leaf beetles may enter a state of suspended animation after being startled. Even after confirming safety, the beetles may revive and remain on the tea leaves, continuing to feed on them, thus affecting the effectiveness of pest control.

[0004] Therefore, it is necessary to design a spraying device for tea gardens that can attract and kill leaf beetles during the spraying process, thereby improving the pest control effect. Summary of the Invention

[0005] To address the drawback that some leaf beetles tend to enter a state of suspended animation when startled, and then, after being confirmed safe, revive and continue to gnaw on the tea leaves, thus affecting the effectiveness of pest control, the technical problem to be solved by this invention is to provide a spraying device for removing leaf beetles in tea gardens that can attract and kill leaf beetles during the spraying process, thereby improving the pest control effect.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] A spraying device for controlling leaf beetles in tea gardens includes a box and a frame embedded and fixed to the top of the box. A liquid inlet pipe is connected to the box. The top of the frame has evenly spaced openings. A collection frame for collecting the killed leaf beetles is placed inside the frame. A handle is fixed to the box. A fixing frame is fixed to the outside of the frame. A T-shaped spray pipe is rotatably connected to the top of the fixing frame. A servo motor is mounted on the outer side of the fixing frame, and the servo motor is driven by the T-shaped spray pipe through two gears. A water pump is mounted on the outer side of the box. The inlet of the water pump is connected to the box, and the outlet of the water pump is connected to an outlet pipe. The tail end of the outlet pipe passes through the fixing frame and is rotatably connected to the end of the T-shaped spray pipe. The device also includes a yellow LED light, a conical ring, an electric lead screw, a fixing brush, a sealing assembly, and a collection assembly. The collection assembly is installed between the box and the frame. Between the T-shaped nozzles, a system is used to collect and return residual pesticide from the nozzles. The sealing assembly is mounted on a fixed frame, and the yellow LED light is fixed between the fixed frame and the frame. A fixed brush is embedded in the yellow LED light, and a conical ring is slidably mounted on the yellow LED light. The conical ring contacts the sealing assembly and the fixed brush. An electric screw threadedly connected to the conical ring is installed in the middle of the inner side of the fixed frame. The yellow LED light is used to attract leaf beetles, causing them to come into contact with the yellow LED light. The electric screw is activated to control the conical ring to move downward, disengaging it from the sealing assembly. The sealing assembly then closes the fixed frame. Subsequently, the conical ring moves downward to scrape off the leaf beetles from the yellow LED light, causing them to fall into the frame for elimination.

[0008] A further preferred embodiment of the present invention is as follows: the sealing component includes an arc-shaped cover plate that is rotatably connected to the circumference of the fixed frame at uniform intervals to seal the inside of the fixed frame. A connecting spring is connected inside the fixed frame, and a trigger ring is connected to the tail end of the connecting spring. The trigger ring contacts a conical ring and is threadedly connected to the shaft of the arc-shaped cover plate to drive the arc-shaped cover plate to swing.

[0009] A further preferred embodiment of the present invention is as follows: the collection component includes swing frames symmetrically rotatably connected to the left and right sides of the top of the T-shaped nozzle. The swing frames on the same side contact each other to form a shell covering the spray area of ​​the T-shaped nozzle. A liquid outlet is opened at the bottom of the swing frame. A connecting rod is rotatably connected to the side of the left and right swing frames that are close to each other. A trigger rod is symmetrically slidably connected to the top of the T-shaped nozzle. The end of the trigger rod is rotatably connected to the end of the connecting rod. A return spring is symmetrically connected between the trigger rod and the T-shaped nozzle. A trigger assembly is provided on the fixed frame to drive the trigger rod to move. A return assembly is provided between the fixed frame and the box to drain the dripping medicine back into the box.

[0010] A further preferred embodiment of the present invention is: the reflux assembly includes a receiving ring fixed to the outside of the fixed frame, the receiving ring being located below the liquid outlet of the swing frame to collect the medicine discharged from the swing frame, and a reflux pipe connecting the bottom of the receiving ring to the top of the box.

[0011] A further preferred embodiment of the present invention is as follows: the triggering component includes an inclined ring rotatably connected to the top of the fixed frame, the inclined surface of the inclined ring contacting the end of the trigger rod for driving the trigger rod to move, and a magnetic ring in magnetic contact with the inclined ring is fixedly connected to the top of the fixed frame circumferentially.

[0012] A further preferred embodiment of the present invention includes a sealing assembly, which includes a sealing plate that is slidably connected to the inner side of the frame at uniform intervals. The sealing plate contacts the opening of the frame to seal the inside of the frame. A compression spring is connected between the sealing plate and the frame. A drive rod located above the sealing plate is fixedly connected at uniform intervals along the circumference of the bottom of the conical ring to drive the sealing plate to move downward. A scraping assembly is provided between the frame and the water outlet pipe to scrape off leaf beetles attached to the inner wall of the conical ring.

[0013] A further preferred embodiment of the present invention is as follows: the scraping assembly includes an electrically controlled three-way valve installed on the water outlet pipe, a water spray pipe corresponding to the electrically controlled three-way valve is connected to the water outlet pipe, the tail end of the water spray pipe is fixedly inserted through the frame, and a scraping ring is rotatably connected to the inner side of the conical ring in the circumferential direction.

[0014] A further preferred embodiment of the present invention includes a filter screen fixed within the collection frame to filter leaf beetles from the medicine solution.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. First, start the servo motor to make the T-shaped spray nozzle rotate forward. Then, start the water pump to draw the pesticide into the outlet pipe. The pesticide in the outlet pipe is sprayed onto the tea leaves through the T-shaped spray nozzle, thus treating the tea leaves and killing leaf beetles. At the same time, turn on the yellow LED light to attract leaf beetles. Then, start the electric screw to move the conical ring downward. The arc-shaped cover first closes the fixing frame. The conical ring then removes the leaf beetles on the yellow LED light into the collection box for killing. This prevents the leaf beetles from feigning death and remaining on the tea leaves to eat them again, thereby improving the insect control effect.

[0017] 2. With the help of the sealing plate, whenever the removed leaf beetles fall into the collection box, the sealing plate can seal the inside of the box, preventing the leaf beetles in the collection box from flying out of the opening and eating the tea leaves again, thus ensuring the complete elimination of the leaf beetles.

[0018] 3. With the help of the filter screen, whenever the pesticide and the removed leaf beetles fall into the collection box, the filter screen can separate the pesticide and the leaf beetles, which can prevent the pesticide and leaf beetles from mixing together and affecting subsequent treatment, thus facilitating the separation and treatment of pesticide and leaf beetles.

[0033] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0034] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0035] Example: A spraying device for controlling leaf beetles in tea gardens, please refer to [link / reference]. Figures 1-7As shown, the device includes a housing 1 and a frame 2 embedded and fixed to the top of the housing 1. A liquid inlet pipe is connected to the rear right side of the top of the housing 1. Three evenly spaced openings are located on the top of the frame 2. A collection frame 3 is placed inside the frame 2 to collect the killed leaf beetles. A handle 4 is fixed to the lower part of the rear side of the housing 1. A mounting bracket 5 is fixed to the top left side of the frame 2. A T-shaped nozzle 9 is rotatably connected to the top center of the mounting bracket 5. A servo motor 8 is installed on the upper left side of the mounting bracket 5. The servo motor 8 is connected to the lower outer side of the T-shaped nozzle 9 via two gears. A water pump 6 is installed on the outer left side of the housing 1. The inlet of the water pump 6 is connected to the housing 1, and the outlet of the water pump 6 is connected to the outlet pipe 7. The tail end of the outlet pipe 7 passes through the fixing frame 5 and is rotatably connected to the bottom end of the T-shaped nozzle 9. The system also includes a yellow LED light 10, a conical ring 11, an electric lead screw 111, a fixed brush 112, a sealing assembly, and a collection assembly. The collection assembly is installed between the housing 1 and the T-shaped nozzle 9. When the collection component is in operation, it can collect and return the residual medicine on the T-shaped nozzle 9. The sealing component is installed on the fixing frame 5. The yellow LED light 10 is fixed between the fixing frame 5 and the top left side of the frame 2. A fixed brush 112 is embedded and fixed to the left side of the yellow LED light 10. A conical ring 11 is slidably fitted on the yellow LED light 10. The conical ring 11 contacts the sealing component and the fixed brush 112. An electric lead screw 11 is vertically installed in the middle of the inner side of the fixing frame 5. 1. The electric lead screw 111 is threadedly connected to the middle of the conical ring 11. The yellow LED light 10 is used to attract leaf beetles, so that the leaf beetles come into contact with the yellow LED light 10. The electric lead screw 111 is activated to control the conical ring 11 to move downward. The conical ring 11 disengages from the sealing component. The sealing component operates to seal the inside of the fixing frame 5. Then the conical ring 11 moves downward to scrape off the leaf beetles on the yellow LED light 10, so that the leaf beetles fall into the frame 2 for killing.

[0036] Please see Figure 3 As shown, the sealing assembly includes a trigger ring 12, a connecting spring 121, and an arc-shaped cover plate 122. Three arc-shaped cover plates 122 are rotatably connected to the fixing frame 5 at even intervals along the circumference. The arc-shaped cover plates 122 can seal the inside of the fixing frame 5. The connecting spring 121 is connected to the top of the fixing frame 5. The trigger ring 12 is connected to the tail end of the connecting spring 121. The bottom of the trigger ring 12 contacts the top of the conical ring 11. The outer side of the trigger ring 12 is threaded to the upper side of the shaft of the arc-shaped cover plate 122. When the trigger ring 12 moves downward, the trigger ring 12 can drive the arc-shaped cover plate 122 to swing.

[0037] Please see Figure 6 and Figure 7As shown, the collection assembly includes a reflux assembly, a swing frame 132, a connecting rod 133, a trigger rod 134, a return spring 135, and a trigger assembly. Two swing frames 132 are symmetrically rotatably connected to the left and right sides of the top of the T-shaped nozzle 9. The two swing frames 132 on the same side contact each other to form a shell covering the spray area of ​​the T-shaped nozzle 9. A liquid outlet is opened at the bottom of the swing frame 132 near the fixed frame 5. A connecting rod 133 is rotatably connected to the upper part of the side of the swing frames 132 that are close to each other. A trigger rod 134 is symmetrically slidably connected to the top of the inside of the T-shaped nozzle 9. The ends of the trigger rods 134 that are far apart from each other are rotatably connected to the bottom ends of the connecting rods 133 on the left and right sides, respectively. Return springs 135 are symmetrically connected between the top of the trigger rod 134 and the top of the inside of the T-shaped nozzle 9. A trigger assembly is provided on the fixed frame 5. When the trigger rod 134 rotates clockwise, the trigger assembly can drive the trigger rod 134 to move upwards. A reflux assembly is installed between the fixed frame 5 and the housing 1. When the reflux assembly is in operation, it can discharge the dripping medicine back into the housing 1. The reflux assembly includes a receiving ring 13 and a reflux pipe 131. The receiving ring 13 is fixedly connected to the upper outer side of the fixed frame 5. The receiving ring 13 is located below the liquid outlet of the left and right swing frames 132. The receiving ring 13 can collect the medicine discharged from the swing frames 132. The bottom left side of the receiving ring 13 is aligned with the top left side of the housing 1. A return pipe 131 is connected between the sides; the trigger assembly includes a slanted ring 136 and a magnetic ring 137. The slanted ring 136 is rotatably connected to the top of the outer side of the fixed frame 5. The slanted surface of the slanted ring 136 contacts the ends of the trigger rods 134 on the left and right sides. When the trigger rods 134 rotate clockwise, the slanted ring 136 can drive the trigger rods 134 to move upward. The magnetic ring 137 is fixedly connected to the top of the outer side of the fixed frame 5 in a circumferential direction. The magnetic ring 137 is in magnetic contact with the inner side of the slanted ring 136.

[0038] Initially, the connecting spring 121 is compressed. First, pour an appropriate amount of medicine into the box 1, then hold the handle 4 and push the device to the designated position. Then, start the servo motor 8, which drives the T-shaped nozzle 9 to rotate forward through two gears. The forward rotation of the T-shaped nozzle 9 drives the trigger rod 134 to rotate forward. Since the magnetic ring 137 magnetically attracts the inclined ring 136, the trigger rod 134 slides on the inclined surface of the inclined ring 136. The inclined ring 136 drives the trigger rod 134 to move upward, compressing the reset spring 135. The trigger rod 134 drives the front and rear swing frames 132 to swing upward through the connecting rod 133. When the front and rear swing frames 132 stop swinging upward, they cover the liquid outlet end of the T-shaped nozzle 9. The trigger rod 134 continues to move upward until the inclined surface of the inclined ring 136 reaches its maximum stroke. The trigger rod 134 stops moving upwards. The trigger rod 134 rotates clockwise, causing the inclined ring 136 to rotate clockwise. Then, the water pump 6 starts, drawing the pesticide from the tank 1 into the outlet pipe 7. The pesticide in the outlet pipe 7 flows into the T-shaped spray pipe 9. The T-shaped spray pipe 9 rotates clockwise, evenly spraying the pesticide onto the tea leaves, completing the pesticide treatment and killing the leaf beetles on the tea leaves. Simultaneously, the yellow LED light 10 is activated. Due to the leaf beetles' attraction to yellow, the yellow LED light 10 emits yellow light to attract them, causing them to come into contact with the yellow LED light 10. When there are a large number of leaf beetles on the yellow LED light 10, the electric screw 111 reverses, causing the conical ring 11 to move downwards, disengaging the conical ring 11 from the trigger ring 12. Upon contact, due to the action of the connecting spring 121, the trigger ring 12 moves downward, causing the three arc-shaped cover plates 122 to swing through the threads. The swinging of the three arc-shaped cover plates 122 seals the inside of the fixing frame 5, preventing leaf beetles from flying out of the fixing frame 5 and becoming difficult to kill. Subsequently, the conical ring 11 continues to move downward, removing leaf beetles from the yellow LED light 10. The fixed brush 112 can prevent leaf beetles from entering the yellow LED light 10 and affecting the use of the light. The removed leaf beetles fall through the opening of the frame 2 into the collection box 3 and are killed, preventing leaf beetles from feigning death and remaining on the tea leaves to eat them again, thereby improving the insect removal effect. When the conical ring 11 moves downward to its maximum stroke, the electric screw 111 is activated to rotate forward, driving The conical ring 11 moves upward to reset, and the reset of the conical ring 11 drives the trigger ring 12 to move upward to reset. The connecting spring 121 is compressed, and the reset of the trigger ring 12 drives the three arc-shaped cover plates 122 to swing in the opposite direction to reset via the thread. The arc-shaped cover plates 122 stop and close the inside of the fixing frame 5. The yellow LED light 10 attracts leaf beetles again. After the tea leaves are sprayed, the water pump 6 is turned off, and the T-shaped spray pipe 9 stops spraying the pesticide. Then, the servo motor 8 is started, and the T-shaped spray pipe 9 is reversed through two gears. The reverse rotation of the T-shaped spray pipe 9 drives the trigger rod 134 to reverse and disengage from the inclined surface of the inclined ring 136. Due to the action of the connecting spring 121, the trigger rod 134 moves downward to reset, and the connecting rod 133 drives the front and rear swing frames 132 to swing downward to reset.The swing frames 132 on both sides collect the liquid dripping from the outlet of the T-shaped spray nozzle 9. The collected liquid is discharged into the receiving ring 13, which then discharges the liquid back into the housing 1 through the return pipe 131 for reuse, preventing waste. The device is then moved again to spray the tea leaves at the next location.

[0039] Please see Figures 8-11 As shown, it also includes a sealing assembly installed between the frame 2 and the conical ring 11. The sealing assembly includes a drive rod 14, a sealing plate 141, a compression spring 142, and a scraping assembly. Three sealing plates 141 are vertically slidably connected at even intervals along the circumference of the upper inner side of the frame 2. The sealing plates 141 contact the opening of the frame 2, and the sealing plates 141 can seal the inside of the frame 2. Two compression springs 142 are connected between the sealing plates 141 and the upper inner side of the frame 2. Three drive rods 14 are fixedly connected at even intervals along the circumference of the bottom of the conical ring 11. The drive rods 14 are located above the sealing plates 141. When the drive rods 14 move downward and contact the sealing plates 141, the drive rods 14 can drive the sealing plates 141 to move downward. A scraping assembly is provided between the water outlet pipe 7 and the water outlet pipe 7. When the scraping assembly is in operation, it can scrape off the leaf beetles attached to the inner wall of the conical ring 11. The scraping assembly includes a scraping ring 143, a water spray pipe 144 and an electrically controlled three-way valve 145. The electrically controlled three-way valve 145 is installed at the lower part of the water outlet pipe 7. The water spray pipe 144 is connected to the lower front side of the water outlet pipe 7. The water spray pipe 144 corresponds to the electrically controlled three-way valve 145. The tail end of the water spray pipe 144 is fixedly inserted through the upper left side of the frame 2. The scraping ring 143 is rotatably connected to the upper inner side of the conical ring 11. The scraping ring 143 is composed of a circular ring and an inclined scraper. The circular ring is rotatably connected to the upper inner side of the conical ring 11. The inclined scraper is evenly spaced and fixed to the circumference of the circular ring. The inclined scraper is in contact with the inner wall of the conical ring 11.

[0040] When the conical ring 11 moves downward, it drives the scraper ring 143 and the drive rod 14 to move downward. The drive rod 14 moves downward and contacts the sealing plate 141, which in turn drives the sealing plate 141 to move downward. The compression spring 142 is compressed, and the sealing plate 141 stops sealing the inside of the frame 2. The leaf beetles removed by the yellow LED light 10 fall through the opening in the frame 2 into the collection box 3 for killing. At the same time, the electronically controlled three-way valve 145 is activated to connect the water outlet pipe 7 and the spray pipe 144. Some of the medicine in the water outlet pipe 7 is discharged into the spray pipe 144, and the spray pipe 144 sprays the medicine out and onto the scraper ring 143. Upon contact, the pesticide drives the scraper ring 143 to reverse, removing leaf beetles attached to the inner wall of the conical ring 11. The pesticide used to remove the leaf beetles falls through the opening of the frame 2 into the collection frame 3 for collection. When the conical ring 11 moves upward to reset, the electrically controlled three-way valve 145 is activated to close the spray pipe 144, stopping the spray of pesticide. The conical ring 11 stops reversing and resets, driving the drive rod 14 to move upward to reset. The drive rod 14 resets and disengages from the sealing plate 141. Due to the action of the compression spring 142, the sealing plate 141 moves upward to reset, sealing the inside of the frame 2. This prevents leaf beetles in the collection frame 3 from flying out of the opening of the frame 2 and feeding on the tea leaves again, thus ensuring the complete elimination of leaf beetles.

[0041] Please see Figure 12 As shown, it also includes a filter screen 15. The filter screen 15 is fixedly attached to the lower inner side of the collection frame 3 along the circumferential direction. The filter screen 15 can filter out leaf beetles in the medicine.

[0042] When the pesticide and leaf beetles fall into the collection frame 3, both come into contact with the filter screen 15. The filter screen 15 filters and collects the leaf beetles, while the pesticide passes through the filter screen 15 and falls to the bottom of the collection frame 3 for collection. When the collection frame 3 is removed, the leaf beetles on the filter screen 15 can be removed, and the pesticide in the collection frame 3 can be poured out. Then, the collection frame 3 can be placed back into the frame 2. This prevents the pesticide and leaf beetles from mixing and affecting subsequent processing, thus facilitating the separation of the pesticide and leaf beetles.
