Description

Technical Field

[0001] This invention relates to the field of pest and disease control technology, and in particular to a trapping and spraying device for controlling underground pests and diseases. Background Technology

[0002] Crop underground pests and diseases refer to diseases and pests that affect the underground parts of crops (such as roots, stems, and tubers). These pests and diseases are omnivorous and can harm a variety of crops, including grains, cotton, oilseeds, vegetables, sugar crops, tobacco, hemp, medicinal herbs, and forage grasses. They are also major threats to fruit trees and forest nurseries. Under the premise of integrated pest management, the application of chemical agents remains the primary measure for controlling underground pests at this stage. It is essential to adhere to scientific and rational pesticide use to achieve both economical and effective pest control while reducing and preventing excessive pesticide residues from polluting the environment.

[0003] According to the invention patent CN114931136B, a forest pest and disease control underground application device includes a medicine box, and further includes: a fixed cylinder fixedly connected to the bottom of the medicine box, and the medicine box and the fixed cylinder are in communication; a connecting block rotatably connected to the bottom of the fixed cylinder; a rotating cylinder rotatably connected to the bottom of the connecting block, the outer wall of the rotating cylinder is provided with spiral blades, and the bottom of the rotating cylinder is provided with a conical cylinder; a conical block slidably connected to the conical cylinder at the bottom of the rotating cylinder; a fixed block slidably connected to the rotating cylinder, and the bottom of the fixed block is provided with a nozzle; a cylindrical cylinder is fixedly connected to the rotating cylinder, a second piston is slidably connected to the cylindrical cylinder, and the top of the cylindrical cylinder is provided with a telescopic tube communicating with the nozzle; this invention facilitates the injection of medicine underground, effectively controls underground pests, and effectively protects forests.

[0004] Although the above-mentioned technical solution can inject the drug into the ground to achieve the purpose of killing insects, the solution only releases the drug through the lower opening of the cone-shaped tube, which limits the range of drug release and does not have the effect of attracting pests. In addition, the limited range of drug release not only results in poor insecticidal effect, but also wastes the insecticide as the drug soaks the soil. Summary of the Invention

[0005] The purpose of this invention is to provide a trapping and spraying device for the control of underground pests and diseases. It can not only disinfect pests underground, but also improve the insecticidal effect by increasing the release range of the drug, while avoiding the waste of insecticide.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A device for attracting and applying pesticides to control underground pests includes a fixed tube with an open lower end, a conical and hollow base connected to the lower end of the fixed tube, a silent fan installed on the inner wall of the fixed tube near its open end, multiple air inlets evenly spaced on the outer wall of the fixed tube at the location of the silent fan, a liquid storage cylinder above the silent fan inside the fixed tube, a partition dividing the liquid storage cylinder into a pesticide chamber and a liquid storage chamber on one side of the bottom of the inner wall of the liquid storage cylinder along its height direction, an air pump installed at the upper end of the liquid storage cylinder inside the fixed tube, several heat dissipation holes on the outer wall of the fixed tube at the location of the air pump, and a first three-way pipe connected to the air pump outlet. A two-position three-way reversing valve is installed at one end of the first three-way pipe and connected to it. One end of the two-position three-way reversing valve is connected to a first air guide pipe extending into the pesticide chamber, and the other end is connected to a second air guide pipe extending into the liquid storage chamber.

[0008] A battery and control panel are installed above the air pump inside the fixed tube. A control button electrically connected to the control panel is provided on the outer wall of the fixed tube. On the upper left and right sides of the outer wall of the liquid storage cylinder, at the positions of the liquid chamber and the liquid storage chamber, there are inlet pipes that communicate with and extend out of the upper end of the outer wall of the fixed tube. Each inlet pipe can be detachably connected to a plug that is sealed to it. Several slots with equal spacing are opened inward from the lower side of the outer wall of the base. A connecting frame is provided on the upper side of the inner wall of the base. A box with an open upper end is provided on the upper end of the connecting frame. A sponge pad is provided inside the box. A spraying component is provided on the lower end of the connecting frame. The other end of the first three-way pipe is connected to a third air guide pipe connected to the lower side of the outer wall of the spraying component.

[0009] A first liquid guide tube is provided between the bottom of the outer wall of the liquid chamber and one end of the spraying assembly, and a second liquid guide tube is provided between the bottom of the outer wall of the storage chamber and the other end of the outer wall of the spraying assembly. A third liquid guide tube extending into the box body is connected to one side of the bottom of the outer wall of the storage chamber. Multiple horn-shaped connecting pipes are connected to the upper part of the outer wall of the base. One end of the outer wall of each connecting pipe can be detachably connected to a diffusion assembly. The air pump, the two-position three-way reversing valve, the spraying assembly, and the battery are all electrically connected to the control panel.

[0010] By adopting the above technical solution, when using it, first dig a pit in the location where pests and diseases need to be eliminated, and place the base in the soil. Then, connect the diffusion component and the connecting pipe and bury them in the soil. Next, place the base in the pit, cover it with soil and keep the pit hollow. Then, remove the plug and add insecticide to the liquid chamber and pheromone to the storage chamber through the corresponding liquid inlet pipes. Then, replace the plug, press the control button, and the battery provides power to control the air pump and spraying component through the control panel. The gas generated by the air pump is divided into two gas paths through the first three-way pipe. One gas path is divided into two branch gas paths again when it passes the position of the two-position three-way reversing valve. One branch gas path is delivered to the liquid chamber through the first air guide pipe to pressurize it. The other branch gas path is delivered to the storage chamber through the second air guide pipe to pressurize it. The other gas path is delivered to the spraying component through the third air guide pipe. After pressurization, the pheromone in the storage chamber will first flow into the box on the connecting frame through the third liquid guide pipe and wet the sponge pad.

[0011] Then the silent fan starts working, and outside air enters the fixed pipe through the air inlet, dispersing the scent of the pheromone. At the same time, the second liquid guide tube delivers the pheromone to the spray assembly. At this time, one end of the two-position three-way reversing valve is closed and the other end is open. The air pump pressurizes the liquid storage chamber and sprays the pheromone from the spray assembly. After a period of time, the air pump stops working, and the silent fan diffuses the sprayed pheromone through the slot and diffusion assembly into the soil layer, targeting the space where the target pests are frequently attracted and settling. After a period of time, the air pump resumes working. At this time, one end of the two-position three-way reversing valve is open and the other end is closed. The air pressure in the liquid chamber increases, delivering the insecticide to the spray assembly and spraying it out with the help of the third air guide tube to complete the elimination of the target pests. When spraying the pheromone and insecticide through the spray assembly, the operation is intermittent through the control panel, which reduces waste of the pesticide and improves the killing effect.

[0012] A further feature of the present invention is that a positioning ring is provided above the outer wall of the base, and a cover for blocking the base is detachably connected to the upper end of the outer wall of the positioning ring.

[0013] By adopting the above technical solution, soil can be prevented from entering the base when covering the pit with soil.

[0014] A further configuration of the present invention is as follows: the spraying assembly includes a second three-way pipe, two solenoid valves respectively installed at both ends of the second three-way pipe, and an atomizing nozzle connected to the lower end of the second three-way pipe.

[0015] A further feature of the present invention is that a handle is provided at the upper end of the outer wall of the fixed tube, and the control button is located on one side of the upper end of the inner wall of the handle.

[0016] A further embodiment of the present invention is that the diffusion component includes a positioning tube with openings at both ends, a plurality of vent holes provided on the left and right sides of the upper end of the outer wall of the positioning tube and arranged along its length, and a blocking component provided along the upper end of the outer wall of the positioning tube and used to block the vent holes, wherein a gap is left between the blocking component and the upper end of the outer wall of the positioning tube.

[0017] By adopting the above technical solution, the diffusion component can increase the diffusion range of the sex pheromone, thereby attracting pests within the effective range and improving the killing effect.

[0018] A further embodiment of the present invention is that the shielding component includes an arc-shaped baffle and a plurality of support rods disposed on the left and right sides of the lower end of the baffle and distributed at equal intervals.

[0019] By adopting the above technical solution, when burying the positioning tube in the soil, it is possible to avoid the soil clogging the air pores and thus affecting the diffusion of the sex attractant.

[0020] A further feature of the present invention is that the lower end of the inner wall of the box is provided with a plurality of water-absorbing rods that extend out of its outer wall and correspond one-to-one with the diffusion component and all extend into the corresponding positioning tube.

[0021] By adopting the above technical solution, the diffusion range of the sex attractant can be further expanded through a moistened absorbent stick.

[0022] A further feature of the present invention is that a mesh is provided on the outer wall of the fixed tube at each air inlet and each heat dissipation hole, and the mesh is connected thereto.

[0023] By adopting the above technical solution, insects can be prevented from entering the fixed tube and affecting the service life of each working component.

[0024] In summary, the present invention has the following beneficial effects:

[0025] Firstly, this invention can not only disinfect pests underground, but also improve the insecticidal effect by increasing the release range of the drug, while avoiding the waste of insecticide.

[0026] Secondly, the present invention can expand the attraction range of pests by combining the diffusion component and the silent fan, thereby further improving the killing effect on underground pests.

[0027] Thirdly, the spray component of the present invention can not only atomize the insecticide liquid to improve the killing effect and rate of pests in the base, but also atomize the pheromone to facilitate the diffusion of the atomized pheromone and increase the attraction effect.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] An air pump 19 is installed inside the fixed pipe 1 at the upper end of the liquid storage cylinder 15. Several arrayed heat dissipation holes 2 are opened inwards on the outer wall of the fixed pipe 1 at the location of the air pump 19. A mesh 21 connected to each air inlet 14 and each heat dissipation hole 2 is installed on the outer wall of the fixed pipe 1. The air outlet of the air pump 19 is connected to a first three-way pipe 22. A two-position three-way reversing valve 23 is installed at one end of the first three-way pipe 22 and connected thereto.

A handle 29 is provided at the upper end of the outer wall of the fixed pipe 1. A control button 3 electrically connected to the control panel 28 is provided on one side of the upper end of the inner wall of the handle 29. An inlet pipe 31 is provided on the left and right sides of the upper end of the outer wall of the liquid storage cylinder 15 at the positions of the liquid storage chamber 17 and the liquid storage chamber 18, which communicates with it and extends out of the upper end of the outer wall of the fixed pipe 1. Each inlet pipe 31 can be detachably connected to a plug 32 that is sealed to it at one end of the end extending out of the fixed pipe 1.

[0041] The lower outer wall of the base 11 has several equally spaced slots 12. A connecting frame 33 is fitted onto the upper part of the inner wall of the base 11. The upper end of the connecting frame 33 has a box 34 with an open top. A sponge pad 35 is placed inside the box 34. The lower end of the connecting frame 33 has a spray assembly 36. The spray assembly 36 includes a second three-way pipe 37, two solenoid valves 38 respectively installed at both ends of the second three-way pipe 37, and an atomizing nozzle 39 connected to the lower end of the second three-way pipe 37. The other end of the three-way pipe 22 is connected to a third air guide pipe 26 that is connected to one side of the lower end of the outer wall of the second three-way pipe 37. A first liquid guide pipe 4 is provided between the bottom of the outer wall of the liquid chamber 17 and the solenoid valve 38 corresponding to one end of the liquid spraying assembly 36. A second liquid guide pipe 41 is provided between the bottom of the outer wall of the liquid storage chamber 18 and the solenoid valve 38 corresponding to the other end of the outer wall of the liquid spraying assembly 36. A third liquid guide pipe 42 that extends into the box body 34 is connected to one side of the bottom of the outer wall of the liquid storage chamber 18.

[0042] The upper part of the outer wall of the base 11 is connected to a plurality of equally spaced and trumpet-shaped connecting pipes 43. One end of the outer wall of each connecting pipe 43 can be detachably connected to a diffusion component 44. The diffusion component 44 includes a positioning pipe 45 with open ends, a plurality of vent holes 46 opened on the left and right sides of the upper end of the outer wall of the positioning pipe 45 and arranged along its length, and a blocking component 47 arranged along the upper end of the outer wall of the positioning pipe 45 to block the vent holes 46. A gap is left between the blocking component 47 and the upper end of the outer wall of the positioning pipe 45. The blocking component 47 includes an arc-shaped baffle 48 and a plurality of support rods 49 arranged on the left and right sides of the lower end of the baffle 48 and equally spaced. The lower end of the inner wall of the box 34 is provided with a plurality of water-absorbing rods 5 extending out of its outer wall and corresponding one to one with the diffusion component 44 and extending into the corresponding positioning pipe 45. The air pump 19, the two-position three-way reversing valve 23, the spraying component 36 and the battery 27 are all electrically connected to the control panel 28.

[0043] Instructions for use: First, dig a hole large enough to hold the base 11 at the location where pest and disease control is needed. Connect the diffuser component 44 to the connecting pipe 43 and place the shielding component 47 facing upwards. Then, place the water-absorbing rod 5 into the positioning tube 45 of the corresponding diffuser component 44. Next, place the base 11 into the hole and bury the positioning tube 45 in the soil. The shielding component 47 will separate the soil from the air vent 46. At the same time, the baffle 48 on the support rod 49 keeps the upper end of the positioning tube 45 hollow. Finally, place the cover 52 on the positioning ring 51 to cover the hole. Cover the pit with soil to keep it hollow. Then remove the plug 32 and add insecticide to the liquid chamber 17 of the storage cylinder 15, which is divided by the partition 16, through the corresponding liquid inlet pipe 31. Add pheromone to the liquid chamber 18. Then replace the plug 32, press the control button 3 on the handle 29, and use the battery 27 to provide power to control the air pump 19 and the spraying assembly 36 through the control panel 28. The heat generated by the air pump 19 can be discharged through the heat dissipation hole 2, while the screen 21 can prevent insects from entering the fixed pipe 1 through the heat dissipation hole 2 and the air inlet 14.

[0044] The gas generated by the air pump 19 is divided into two air paths through the first three-way pipe 22. One air path is further divided into two branch air paths when it passes the position of the two-position three-way reversing valve 23. One branch air path is delivered to the liquid chamber 17 through the first air guide pipe 24 and pressurized appropriately. The other branch air path is delivered to the liquid storage chamber 18 through the second air guide pipe 25 and pressurized appropriately. The other air path is delivered to the lower end of the second three-way pipe 37 of the spraying assembly 36 through the third air guide pipe 26. The sex attractant in the pressurized liquid storage chamber 18 will first flow into the box 34 on the connecting frame through the third liquid guide pipe 42 and wet the sponge pad 35. At the same time, the sex attractant will wet the water absorbent rod 5 and flow into the positioning tube 45 along the water absorbent rod 5. The odor of the sex attractant in the positioning tube 45 will diffuse into the soil layer through the vent 46.

[0045] Then the silent fan 13 starts working, and outside air enters the fixed pipe 1 through the air inlet 14, blowing away the scent of the sex attractant and flowing along the positioning pipe 45. At the same time, the corresponding solenoid valve 38 on the second liquid guide pipe 41 opens, delivering the sex attractant to the atomizing nozzle 39 of the spraying assembly 36. At this time, one end of the two-position three-way reversing valve 23 is closed and the other end is open. The air pump 19 pressurizes the liquid storage chamber 18, atomizing the sex attractant from the atomizing nozzle 39 and spraying it out. After a period of time, the air pump 19 stops working, and the silent fan 13 diffuses the sprayed sex attractant through the slot 12 and the diffusion assembly 44 into the soil layer to frequently attract the target pests and allow the pests to enter the space of the base 11.

[0046] After a period of time, the air pump 19 continues to work. At this time, one end of the two-position three-way reversing valve 23 is open and the other end is closed, which increases the air pressure in the liquid chamber 17. At the same time, the solenoid valve 38 corresponding to the first liquid guide tube 4 is opened and the insecticide liquid is delivered to the atomizing nozzle 39 in the second three-way tube 37. It works with the third air guide tube 26 to spray it out to disinfect the target pests. During the atomization of the pheromone and insecticide liquid, the gas in the third air guide tube 26 can accelerate the flow rate of the pheromone and insecticide liquid and accelerate the air flow in the base 11. When the pheromone and insecticide liquid are sprayed through the spraying assembly 36, the control panel 28 controls it to work intermittently, which reduces the waste of liquid and improves the killing effect.

[0047] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make inventive modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
