Description

Technical Field

[0001] This invention relates to the field of pest and disease control technology, and in particular to an agricultural pest and disease control device. Background Technology

[0002] Agricultural planting is easily threatened by pests and diseases in the natural environment. The effectiveness of pest and disease control will directly affect the crop yield. Therefore, pest and disease control is an indispensable and crucial part of agricultural planting.

[0003] Traditional pest and disease control methods involve spraying large amounts of pesticides, which is not only physically demanding for workers, but also only provides temporary relief from pests and diseases. Therefore, more and more farmers are choosing to set up control boxes at designated locations. These boxes use insect-attracting lamps to lure insects, and then continuously release insecticidal gases to kill surrounding insects, achieving a long-term, continuous control effect. However, during the control process, the concentration of the insecticidal gas gradually decreases due to continuous release, resulting in poor effectiveness over time. Furthermore, the toxic insecticidal gases disperse during the control process, potentially impacting crop growth. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural pest and disease control device to solve the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions:

An air passage is formed between the outer wall of the inner insect-trapping cylinder and the inner wall of the outer insect-trapping cylinder. A rotating cylinder is rotatably mounted at the top of the inner insect-trapping cylinder. A first air vent is provided through the side wall of the rotating cylinder. The rotating cylinder is filled with a slow-release sponge, which absorbs the insecticide released from the liquid guide tube. A drive motor is installed at the upper end of the fixed plate. A rotating rod is connected to the output end of the drive motor. The rotating rod passes through the rotating cylinder and extends from the bottom of the rotating cylinder. A rotating fan blade is installed at the bottom end of the rotating rod, and the rotating fan blade faces the check valve.

[0009] As a further embodiment of the present invention: the upper end of the rotating drum is provided with a liquid inlet hole, the end of the liquid guide tube near the liquid inlet hole is provided with a liquid inlet head, the end of the liquid guide tube is provided with a liquid inlet, a return spring is provided between the liquid inlet head and the end of the liquid guide tube, a liquid inlet groove is provided at the top of the liquid inlet head, a plug is provided in the center of the liquid inlet groove, the plug is adapted to the liquid inlet, a liquid inlet cavity is provided inside the liquid inlet head, and a liquid passage hole is provided between the liquid inlet cavity and the liquid inlet groove.

[0010] As a further embodiment of the present invention: an annular protrusion is provided circumferentially on the outer wall of the rotating cylinder, and an annular groove is provided circumferentially on the inner wall of the top of the insect-catching inner cylinder, and the annular protrusion is adapted to be slidably installed in the annular groove.

[0011] As a further aspect of the present invention: the insect-attracting lamp includes a lampshade, which is fixedly connected to a support rod, and an annular lamp tube is provided inside the lampshade. The annular lamp tube is connected to the inner wall of the lampshade through a lamp tube fixing bracket.

[0012] As a further embodiment of the present invention: a photovoltaic panel is provided on the surface of the shielding plate, a hook is provided at the top of the shielding plate, and an energy storage battery is fixedly provided at the bottom of the shielding plate. The energy storage battery is electrically connected to the drive motor, the heating wire and the insect-attracting lamp respectively, and the bottom of the shielding plate is fixedly connected to the fixing plate through the connecting column.

[0013] As a further embodiment of the present invention: a support sleeve is evenly provided around the bottom of the support plate, a nut seat is provided at the upper end of the support sleeve, and a support screw is provided through the internal thread of the nut seat.

[0014] The beneficial effects of this invention are:

[0015] (1) By setting up an insect trapping component, the insects are attracted to the vicinity of the insect trapping component by the odor emitted by the insect attracting component. The insects will directly enter the insect trapping inner cylinder through the check valve. At the same time, the slow-release sponge absorbs the insecticidal liquid released by the liquid guide tube and slowly evaporates and releases the insecticidal gas through the first air diffuser, thereby killing the insects. At the same time, the drive motor drives the rotating rod to rotate, which will drive the rotating fan blade to rotate. When the rotating fan blade rotates, it will generate an upward airflow, which can increase the flow of the insecticidal gas emitted in the insect trapping inner cylinder. The insecticidal gas flows through the air passage through the air hole at the top of the rotating cylinder and then flows back into the insect trapping inner cylinder through the air hole at the bottom of the rotating cylinder. As the insecticidal gas continues to evaporate and release, the concentration of the continuously circulating insecticidal gas will gradually increase, which is conducive to improving the insecticidal effect. At the same time, it can also prevent the insecticidal gas from escaping from the insect trapping outer cylinder, effectively preventing the impact on the growth and development of crops in the field.

[0016] (2) By setting up an insect-attracting component, when it is necessary to attract insects, the heating wire is energized to generate high temperature. The insect-attracting vaporizing rod, which is baked by the high temperature, begins to release insect-attracting gas and disperses it outward from the second air outlet. Since the second air outlet is directly opposite the check valve, the insect-attracting gas will be concentrated and guided into the check valve in conjunction with the upward airflow generated by the rotating fan blades. This is conducive to attracting insects directly into the insect-trapping inner tube, which not only improves the insect-attracting effect but also prevents the insect-attracting gas from spreading everywhere and affecting crop production.

[0017] (3) By setting the liquid inlet end and liquid inlet hole, the liquid inlet process will only be carried out when the liquid inlet end and the liquid inlet hole are matched, so that the slow-release sponge absorbs the insecticide liquid intermittently, which can effectively avoid the excessive discharge of insecticide liquid and prevent waste of resources. At the same time, it can also effectively control the time interval of the slow-release sponge absorbing the liquid, thereby controlling the volatilization efficiency and volatilization degree of the insecticide gas.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 and Figure 2As shown, the present invention is an agricultural pest and disease control device, including a shielding plate 1, a fixing plate 2, an insect-attracting lamp 6, and a support plate 7 arranged sequentially from top to bottom. A support rod 5 is provided between the fixing plate 2 and the support plate 7. Insect-trapping components 3 are evenly arranged around the bottom of the fixing plate 2. Insect-attracting components 4 are provided at the bottom of each set of insect-trapping components 3. A pesticide box 201 is fixedly installed at the center of the upper end of the fixing plate 2. The four sides of the pesticide box 201 are connected to one end of a liquid guide pipe 203, and the other end of the liquid guide pipe 203 is connected to the corresponding insect-trapping component 3.

[0031] like Figures 3-5 As shown, the insect-trapping assembly 3 includes an outer insect-trapping cylinder 301 and an inner insect-trapping cylinder 303. An inverted conical check valve 302 is fixedly installed at the bottom of the inner insect-trapping cylinder 303, and the check valve 302 is connected to the bottom of the outer insect-trapping cylinder 301. Ventilation holes 3031 are circumferentially provided at both the upper and lower ends of the inner insect-trapping cylinder 303, forming an air passage between the outer wall of the inner insect-trapping cylinder 303 and the inner wall of the outer insect-trapping cylinder 301. A rotating cylinder 304 is rotatably mounted at the top of the inner insect-trapping cylinder 303, and the side wall of the rotating cylinder 304 is... The cylinder 304 is equipped with a first vent 3041. The cylinder 304 is filled with a slow-release sponge 305, which is used to absorb the insecticide solution released by the liquid guide tube 203. The upper end of the fixed plate 2 is equipped with a drive motor 202. The output end of the drive motor 202 is connected to a rotating rod 306. The rotating rod 306 passes through the cylinder 304 and extends from the bottom of the cylinder 304. The bottom end of the rotating rod 306 is equipped with a rotating fan blade 3061, which faces the check port 302.

[0032] Specifically, by setting up insect-trapping component 3, insect-attracting component 4, and insect-attracting lamp 6, the insects' phototaxis is utilized. Diseased insects are first attracted to the vicinity of insect-attracting component 4 by the insect-attracting lamp 6. Then, the scent emitted by insect-attracting component 4 concentrates the insects near insect-trapping component 3. The insects then enter the inner insect-trapping cylinder 303 directly through check valve 302. Due to the inverted cone design of check valve 302, once the insects enter the inner insect-trapping cylinder 303, it is difficult for them to escape. Simultaneously, the slow-release sponge 305 absorbs the insecticide released by the liquid guide tube 203 and slowly evaporates and releases insecticidal gas through the first vent 3041, thereby killing the insects. The killed insects fall directly to the bottom of the inner insect-trapping cylinder 303 for collection and cleaning. At the same time, the drive motor 202 drives the rotating rod 306 to rotate. 6 will drive the rotating fan blade 3061 to rotate. When the rotating fan blade 3061 rotates, it will generate an upward airflow, which can not only concentrate the odor emitted by the insect-attracting component 4 into the insect-trapping inner cylinder 303, thus preventing the insect-attracting odor from spreading and affecting the insect-attracting effect, but also increase the flow of the insecticidal gas emitted in the insect-trapping inner cylinder 303. This allows the insecticidal gas to flow through the air passage through the vent 3031 at the top of the rotating cylinder 304, and then flow back into the insect-trapping inner cylinder 303 from the vent 3031 at the bottom of the rotating cylinder 304. As the insecticidal gas continues to evaporate and be released, the concentration of the continuously circulating insecticidal gas will gradually increase, which is beneficial to improving the insecticidal effect. At the same time, it can also prevent the insecticidal gas from escaping from the insect-trapping outer cylinder 301, effectively preventing it from affecting the growth and development of crops in the field.

[0033] like Figure 8 As shown, the insect-attracting component 4 includes a mounting plate 401. A connecting rod 402 is fixedly installed on the outer side of the mounting plate 401. The connecting rod 402 is fixedly connected to the insect-catching outer tube 301. A mounting tube 403 is installed at the bottom of the mounting plate 401. An insect-attracting vaporizing rod 404 is installed inside the mounting tube 403. An electric heating wire 405 is installed around the insect-attracting vaporizing rod 404 on the inner wall of the mounting tube 403. A second air vent 4011 is provided through the top of the mounting plate 401. The second air vent 4011 is directly opposite the check valve 302.

[0034] Specifically, the insect-attracting vaporizer 404 used in this embodiment is extremely difficult to volatilize at room temperature. This avoids excessive consumption of the insect-attracting vaporizer 404 before use and also prevents the volatilized gas from affecting agricultural crops. When it is necessary to attract insects, the heating wire 405 is energized to generate high temperature. The insect-attracting vaporizer 404, baked by the high temperature, begins to volatilize insect-attracting gas and disperses it outward from the second vent 4011. Since the second vent 4011 is directly opposite the check valve 302, and with the guiding effect of the rising airflow generated by the rotating fan blades 3061, the dispersed insect-attracting gas will be concentrated and guided into the check valve 302. This facilitates the direct attraction of insects into the insect-trapping inner cylinder 303, improving the insect-attracting effect while preventing the insect-attracting gas from dispersing and affecting crop production.

[0035] like Figure 6 and Figure 7 As shown, a liquid inlet hole 3043 is provided through the upper end of the rotating drum 304. A liquid inlet end 204 is provided at one end of the liquid guide tube 203 near the liquid inlet hole 3043. A liquid inlet port 2031 is provided through the end of the liquid guide tube 203. A return spring 2045 is provided between the liquid inlet end 204 and the end of the liquid guide tube 203. A liquid inlet groove 2042 is provided at the top of the liquid inlet end 204. A plug 2041 is provided in the center of the liquid inlet groove 2042. The plug 2041 is adapted to the liquid inlet port 2031. A liquid inlet cavity 2044 is provided inside the liquid inlet end 204. A liquid passage hole 2043 is provided between the liquid inlet cavity 2044 and the liquid inlet groove 2042.

[0036] Specifically, during the insecticide application process, the insecticide solution in the pesticide tank 201 is delivered through the liquid guide pipe 203. Simultaneously, the rotating drum 304 rotates along with the rotating rod 306, and the inlet end 204 is positioned directly above the rotation path of the inlet hole 3043. When the inlet hole 3043 at the upper end of the rotating drum 304 passes the inlet end 204, the inlet end 204, under the pressure of the return spring 2045, will displace downwards. At this time, the plug 2041 at the top of the inlet end 204 will disengage from the inlet port 2031, while the bottom end of the inlet end 204 engages with the inlet hole 3043. The insecticide solution in the liquid guide pipe 203 then flows through the inlet port 2031 into the inlet tank 2042 and through the liquid passage hole 2043. The liquid enters the rotating drum 304 through the inlet channel 2044, where it is absorbed and evaporated by the slow-release sponge 305. When the inlet hole 3043 disengages from the inlet end 204 as the rotating drum 304 rotates, it pushes the inlet end 204 upward, causing the return spring 2045 to be squeezed again. At the same time, the plug 2041 re-blocks the inlet port 2031, preventing the insecticide liquid from flowing out. That is, the liquid entering process only occurs when the inlet end 204 is engaged with the inlet hole 3043. This allows the slow-release sponge 305 to intermittently absorb the insecticide liquid, effectively preventing excessive discharge of the insecticide liquid and avoiding resource waste. It also effectively controls the time interval of the slow-release sponge 305 absorbing the liquid, thereby controlling the volatilization efficiency and degree of the insecticide gas.

[0037] like Figure 6 As shown, an annular protrusion 3042 is provided circumferentially on the outer wall of the rotating cylinder 304, and an annular groove 3032 is provided circumferentially on the inner wall of the top of the insect-catching inner cylinder 303. The annular protrusion 3042 is adapted to slide and install in the annular groove 3032. The cooperation between the annular protrusion 3042 and the annular groove 3032 can effectively ensure the stability of the rotating cylinder 304 during rotation, and at the same time, it will also apply displacement constraint to the rotating cylinder 304 to avoid unnecessary up and down shaking of the rotating cylinder 304.

[0038] like Figure 9 As shown, the insect-attracting lamp 6 includes a lamp cover 601, which is fixedly connected to the support rod 5. An annular lamp tube 602 is provided inside the lamp cover 601, and the annular lamp tube 602 is connected to the inner wall of the lamp cover 601 through a lamp tube fixing bracket 603.

[0039] like Figure 2 As shown, a photovoltaic panel 101 is provided on the surface of the shielding plate 1, a hook 102 is provided at the top of the shielding plate 1, and an energy storage battery 103 is fixedly provided at the bottom of the shielding plate 1. The energy storage battery 103 is electrically connected to the drive motor 202, the heating wire 405 and the insect-attracting lamp 6 respectively. The bottom of the shielding plate 1 is fixedly connected to the fixing plate 2 through the connecting post 104.

[0040] Specifically, in addition to shielding the structure below from rain, the shield 1 can also effectively absorb solar energy and perform photoelectric conversion using the photovoltaic panel 101. The converted electrical energy will be stored through the energy storage battery 103, which will supply power to the drive motor 202, the heating wire 405, and the insect-attracting lamp 6, thus achieving efficient utilization of resources.

[0041] like Figure 2 As shown, support sleeves 701 are evenly arranged around the bottom of the support plate 7, and a nut seat 703 is provided at the upper end of the support sleeve 701. A support screw 702 is threaded through the nut seat 703.

[0042] Specifically, there are two ways to support and fix this device. One is to suspend and fix it by the hook 102 on the top of the cover plate 1, and the other is to rotate the support screw 702 so that it extends out of the support sleeve 701 and is inserted into the ground for fixation. The appropriate support and fixing method can be selected according to the actual application scenario.

[0043] The working principle of this invention is as follows: Figures 1-9As shown, during use, add sufficient insecticide solution to the agent tank 201, place the insect-attracting vaporizers 404 into each installation cylinder 403, then support and fix the device, turn on the insect-attracting lamp 6 and drive motor 202. Utilizing the phototaxis of insects, diseased insects will first be attracted to the vicinity of the insect-attracting component 4 by the insect-attracting lamp 6. The heating wire 405 is energized to generate high temperature. The insect-attracting vaporizers 404, baked by the high temperature, begin to volatilize insect-attracting gas and disperse it outward from the second air outlet 4011. Since the second air outlet 4011 is directly opposite the check valve 302, in conjunction with the guiding effect of the rising airflow generated by the rotating fan blades 3061, the dispersed insect-attracting gas will be concentrated and guided into the check valve 302, thereby facilitating the direct attraction of insects into the insect-trapping inner cylinder 303. Simultaneously, the slow-release sponge 305 absorbs the insecticide solution released by the liquid guide tube 203 and slowly evaporates and releases insecticidal gas through the first vent 3041, thereby killing insects. The killed insects will fall directly to the bottom of the insect trapping inner cylinder 303 for collection and cleaning. At the same time, the drive motor 202 drives the rotating rod 306 to rotate, which in turn drives the rotating fan blade 3061 to rotate. When the rotating fan blade 3061 rotates, it will generate an upward airflow, which can not only concentrate the odor emitted by the insect attractant component 4 into the insect trapping inner cylinder 303, but also avoid the attractant from spreading out. The insecticidal odor disperses and affects the insect-attracting effect. At the same time, it can increase the flow of insecticidal gas volatilized in the inner insect-trapping cylinder 303. The insecticidal gas flows through the air passage through the vent 3031 at the top of the rotating cylinder 304, and then flows back into the inner insect-trapping cylinder 303 from the vent 3031 at the bottom of the rotating cylinder 304. As the insecticidal gas continues to evaporate and be released, the concentration of the continuously circulating insecticidal gas will gradually increase, which is conducive to improving the insecticidal effect. At the same time, it can also prevent the insecticidal gas from escaping from the outer insect-trapping cylinder 301, effectively preventing it from affecting the growth and development of crops in the field.

[0044] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
