Description
Technical Field
[0001] The present invention relates to the technical field of environmental protection forestry, and specifically to a capturing device for monitoring forestry pests. Background Art
[0002] In the field of forestry pest control, the capturing device is a key equipment for realizing pest situation monitoring and prevention and control. Most traditional forestry pest capturing devices adopt a single-function design, and generally have problems such as the separation of the capturing, killing, and collection links and poor linkage, which are difficult to meet the high efficiency and intelligent requirements of forestry ecological monitoring.
[0003] Most devices set the capturing, killing, and collection functions independently. For example, the common sticky pest board only has the function of capturing, and it needs to be manually cleaned and transferred regularly; although the electric shock pest catcher can kill pests, it lacks an automatic collection mechanism, resulting in the accumulation of pest corpses and affecting subsequent use. This separated design not only increases the manual maintenance cost, but also easily causes secondary escape of pests or pollution of the monitoring environment.
[0004] Traditional devices mostly adopt a static working mode and cannot dynamically adjust the working strategy according to the activity rules of pests (such as day and night habits) or environmental changes. For example, pests that are active at night still consume trapping resources during the day, resulting in low efficiency. Summary of the Invention
[0005] The purpose of the present invention is to provide a capturing device for monitoring forestry pests to solve the problems raised in the prior art.
[0006] To achieve the above purpose, the present invention provides the following technical solutions: The capturing device for monitoring forestry pests includes a fixed box, a capturing unit, a killing unit, and a collection unit. The fixed box is placed on a horizontal ground, the fixed box is fixedly connected to the killing unit, the capturing unit is fixedly connected to the killing unit, the capturing unit has the function of capturing pests, the killing unit is fixedly connected to the collection unit, and the collection unit is fixedly connected to the fixed box.
[0007] The fixed box is used to install the capturing unit, the killing unit, and the collection unit. The capturing unit is used for attracting and capturing forestry pests. The killing unit is used for killing the pests captured by the capturing unit. The collection unit is used for processing the pests killed by the killing unit. When forestry pests need to be captured, the capturing unit attracts and captures the forestry pests, then the killing unit kills the forestry pests, and finally the collection unit uniformly collects the corpses of the pests, thereby protecting the forestry.
[0008] Further, a controller is provided on the fixed box, and a flip cover is provided on the fixed box. The flip cover is connected to the fixed box through a torsion spring.
[0009] The controller is used to control the start and stop of the device. The flip cover is provided to prevent the air extraction pump from sucking the disinfected pest entities into the air extraction pump during the process of sucking pests, which may cause blockage of the air extraction pump.
[0010] Furthermore, the capture unit includes a support column, a mounting platform, a lighting lamp, a storage box and a rain shelter. The support column is fixedly connected to the rain shelter. The mounting platform is fixedly connected to the disinfection unit. The lighting lamp is fixedly installed on the support column. The storage box is fixedly installed on the support column, and the storage box is filled with insect attracting pheromones inside.
[0011] Furthermore, the capture unit further includes a capture net, a vertical column, a motion sensor, a bent rod, a drive coil, a return spring, a pull rope, a magnetic block, an electromagnet, a scraper and an electric telescopic rod. The capture net is fixedly connected to the vertical column. One end of the vertical column is rotatably connected to the rain shelter, and the other end is rotatably connected to the mounting platform. The motion sensor is fixedly installed on the support column. One end of the bent rod is fixedly connected to the mounting platform, and the other end is slidably connected to the capture net. The drive coils are uniformly arranged on the bent rod. One end of the return spring is fixedly connected to the mounting platform, and the other end is fixedly connected to the capture net. The magnetic block is slidably installed on the support column. The magnetic block is connected to the capture net through a pull rope. The electromagnet is fixedly installed on the support column. The scraper is slidably installed on the outer surface of the lighting lamp. A cleaning sponge is arranged inside the scraper. The telescopic end of the electric telescopic rod is fixedly connected to the scraper, and the fixed end of the electric telescopic rod is fixedly installed at the bottom of the lighting lamp through a connecting block. A conductive ring is arranged at the contact end of the capture net and the bent rod. The conductive ring of the capture net is electrically connected to the electric telescopic rod.
[0012] When pests in the forest pass through the capture net and enter the interior, the motion sensor detects the generated motion and determines that the pests have entered the capture range. At this time, the motion sensor feeds back to the controller, and the controller passes an electric current through the electromagnet, thereby pulling the magnetic block to move upward along the support column. Under the action of the self-restoring force of the return spring, the capture net drives the pull rope to rotate along the vertical column and turn outwards, so as to enclose the space and capture the pests inside. During the rotation of the capture net, it slides along the bent rod, so that the effective number of turns of the drive coil gradually increases and the resistance gradually increases, so that the current supplied to the electric telescopic rod gradually decreases. At this time, the electric telescopic rod contracts to drive the scraper to clean the lighting lamp, avoiding impurities left by pests on the lighting lamp during long-term use, which may affect the lighting effect of the lighting lamp and thus affect the capture effect of phototactic pests.
[0013] Furthermore, the capture unit also includes a right-angle rod, a memory bimetallic strip, a baffle, a fixed tube and a conductive column. One end of the right-angle rod is fixedly connected to the pillar, and the other end is fixedly connected to the memory bimetallic strip. The memory bimetallic strip is fixedly connected to the conductive column. The baffle is slidably installed on one side of the storage box. The fixed tube is fixedly installed on the extension of the right-angle rod. A conductive sheet is arranged inside the fixed tube, and the conductive sheet is electrically connected to the lighting lamp.
[0014] Furthermore, the memory bimetallic strip is composed of two upper and lower memory metal strips, and the deformation amount of the upper memory metal strip is greater than the deformation amount of the lower memory metal strip.
[0015] When the temperature is high during the day and the forest pests need to be cleared, the memory bimetallic strip bends upward due to the influence of temperature, thereby driving the conductive column to detach from the fixed tube. During the upward bending process of the memory bimetallic strip, the baffle is pushed to move upward along the storage box, thereby opening the storage box to release the insect attractant pheromones inside, thereby attracting the forest pests into the capture net to complete the pest capture. When the temperature is lower at night, the memory bimetallic strip returns to its initial state. At this time, the conductive column re-extends into the fixed tube and contacts the conductive strip. At this time, the lighting is turned on, attracting phototactic pests into the capture net for capture, thereby improving the efficiency of continuous pest capture during the day and at night.
[0016] Furthermore, the disinfection unit includes a cylinder, an induction coil, a discharge plate, a buffer spring, a push plate and a straight rod. One end of the cylinder is fixedly connected to the mounting table, and the other end is fixedly connected to the fixed box. The induction coil is fixedly installed inside the end of the cylinder away from the fixed box. The discharge plate is electrically connected to the induction coil. One end of the buffer spring is fixedly connected to the inner wall of the cylinder, and the other end is fixedly connected to the discharge plate. The push plate is fixedly installed on the end of the discharge plate close to the fixed box. The discharge plate abuts against the end of the straight rod close to the horizontal foundation. The other end of the straight rod is fixedly connected to the magnetic block. The cylinder is fixedly connected to the collection unit.
[0017] When pests enter the capture net, the vacuum pump is started through the controller to suck the pests into the cylinder. At the same time, the magnetic block moves upward, driving the straight rod to move upward synchronously. At this time, the discharge plate returns to a horizontal state under the action of the buffer spring's own restoring force. In the process of the magnetic block moving upward in the induction coil, the magnetic flux changes, thereby generating current in the induction coil and transmitting it to the discharge plate, causing the discharge plate to discharge and disinfect the pests with electric shock. After the disinfecting is completed, the motion sensor detects that no movement is generated, and changes its polarity, thereby pushing the magnetic block to move downward and pushing the discharge plate to flip down and open. At this time, the push plate pushes the flip cover to open the channel of the fixed box, so that the dead bodies of the pests on the discharge plate fall onto the flip plate for collection.
[0018] Further, the collection unit includes a memory spring, a flip plate, a partition board, a spring airbag, a jet box, a long rod, and an air pump. One end of the memory spring is fixedly connected to the inside of the fixed box, and the other end is fixedly connected to the flip plate. The flip plate is fixedly connected to the long rod. The partition board is arranged inside the fixed box. The spring airbag is arranged below the partition board. The upper part of the spring airbag abuts against the flip plate. The spring airbag is connected to the jet box through a hose. The jet box is fixedly installed inside the fixed box and is located above the flip plate. The air pump is conductively connected to the cylinder through a pipeline. A gravity sensor is arranged below the flip plate. The spring airbag is provided with an air inlet and an air outlet, and one-way valves are arranged inside both the air inlet and the air outlet.
[0019] When the pest corpses fall on the flip plate, the weight of the accumulated pests is detected by the gravity sensor. When a certain weight is reached, the gravity sensor feeds back to the controller, so that the controller conveys current to the memory spring. The memory spring expands and elongates, causing the flip plate to rotate along the long rod, and dumping the pest corpses on the flip plate into another space for unified collection. During the flipping process of the flip plate, the gas compressed in the spring airbag is ejected from the jet box, so as to quickly collect the pest corpses and prevent them from accumulating on the flip plate.
[0020] Further, the push plate abuts against the flip cover arranged on the fixed box.
[0021] In order to isolate the disinfection unit from the collection unit by the flip cover when the air pump is working, preventing the air pump from adsorbing the disinfected pest corpses in the collection unit into the air pump and causing blockage, which affects the disinfection of pests.
[0022] Further, the end of the drive coil close to the support column is the current input end.
[0023] In order to make the capture net slide along the curved rod during the rotation process, so that the effective number of turns of the drive coil gradually increases, the resistance gradually increases, and the current conveyed to the electric telescopic rod gradually decreases. At this time, the electric telescopic rod contracts to drive the scraper to clean the lighting lamp, preventing pests from leaving impurities on the lighting lamp during long-term use, which affects the lighting effect of the lighting lamp and thus affects the capture effect of phototactic pests.
[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. When the forest pests pass through the capture net and enter the interior, the motion sensor detects the movement and determines that the pests have entered the capture range. At this time, the motion sensor feeds back to the controller, and the controller supplies current to the electromagnet, thereby pulling the magnetic block to move upward along the pillar, so that the capture net is driven by the restoring force of the reset spring to pull the pull rope to rotate along the pillar and flip outward, thereby closing the space to capture the pests inside. During the rotation of the capture net, it slides along the bent rod, so that the effective number of turns of the drive coil gradually increases, the resistance gradually increases, and the current delivered to the electric telescopic rod gradually decreases. At this time, the electric telescopic rod contracts to drive the scraper to clean the lighting lamp, so as to avoid the pests leaving impurities on the lighting lamp during long-term use, affecting the lighting effect of the lighting lamp, thereby affecting the capture effect of phototactic pests.
[0025] 2. In the present invention, when the temperature is high during the day and it is necessary to clean the forest pests, the memory bimetallic strip bends upward due to the influence of temperature, thereby driving the conductive column to separate from the fixed tube. During the upward bending of the memory bimetallic strip, the baffle is pushed to move upward along the storage box, thereby opening the storage box to release the internal insect attractant pheromone, thereby attracting the forest pests into the capture net to complete the pest capture. When the temperature is low at night, the memory bimetallic strip returns to its initial state, and the conductive column re-extends into the fixed tube to contact the conductive strip. At this time, the lighting lamp is turned on, and the phototactic pests are attracted to enter the capture net for capture, thereby improving the efficiency of continuous pest capture during the day and at night.
[0026] 3. When the pests enter the capture net, the present invention controls the vacuum pump to start through the controller, thereby sucking the pests into the cylinder. At the same time, the magnetic block moves upward, driving the straight rod to move upward synchronously. At this time, the discharge plate returns to a horizontal state under the action of the buffer spring's own restoring force. During the upward movement of the magnetic block in the induction coil, the magnetic flux changes, thereby generating current in the induction coil and transmitting it to the discharge plate, causing the discharge plate to discharge and disinfect the pests with electric shock. After the disinfecting is completed, the motion sensor detects that no motion is generated, and changes its polarity, thereby pushing the magnetic block to move downward and push the discharge plate to flip downward and open. At this time, the push plate pushes the flip cover to open the channel of the fixed box, so that the dead bodies of the pests on the discharge plate fall onto the flip plate for collection.
[0027] 4. When the dead bodies of insects fall on the flip plate, the present invention detects the weight of the accumulated insects through a gravity sensor. When a certain weight is reached, the gravity sensor feeds back to the controller, so that the controller transmits current to the memory spring, and the memory spring expands and stretches, so that the flip plate rotates along the long rod, and the dead bodies of insects on the flip plate are dumped into another part of the space for unified collection. During the flipping process of the flip plate, the gas in the compressed spring airbag is ejected from the jet box, so that the dead bodies of insects are quickly collected to avoid accumulation on the flip plate.

Detailed Embodiments
[0030] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] Embodiment: As Figures 1 - 9 shown, the present invention provides a technical solution: As Figure 1 shown, a capture device for forestry pest monitoring includes a fixed box 1, a capture unit 2, a disinfection unit 3 and a collection unit 4. The fixed box 1 is placed on a horizontal ground. The fixed box 1 is fixedly connected to the disinfection unit 3. The capture unit 2 is fixedly connected to the disinfection unit 3. The capture unit 2 has the function of capturing pests. The disinfection unit 3 is fixedly connected to the collection unit 4. The collection unit 4 is fixedly connected to the fixed box 1.
[0032] The fixed box 1 is used to install the capture unit 2, the disinfection unit 3 and the collection unit 4. The capture unit 2 is used for the attraction and capture of forestry pests. The disinfection unit 3 is used to disinfect the pests captured by the capture unit 2. The collection unit 4 is used to process the pests eliminated by the disinfection unit 3. When forestry pests need to be captured, the capture unit 2 attracts and captures the forestry pests, then the disinfection unit 3 disinfects the forestry pests, and finally the collection unit 4 uniformly collects the pest corpses, thereby protecting the forestry.
[0033] As Figure 1 shown, a controller is provided on the fixed box 1, and a flip cover is provided on the fixed box 1. The flip cover is connected to the fixed box 1 through a torsion spring.
[0034] The controller is used to control the start and stop of the device. The setting of the flip cover can prevent the flap from closing the lower collection unit 4 during the process of the air pump 47 sucking pests, avoiding sucking the disinfected pest entities into the air pump 47 and causing blockage of the air pump 47.
[0035] As Figure 2 shown, the capture unit 2 includes a support column 21, a mounting table 22, a lighting lamp 23, a storage box 24 and a rain shelter 25. The support column 21 is fixedly connected to the rain shelter 25. The mounting table 22 is fixedly connected to the disinfection unit 3. The lighting lamp 23 is fixedly installed on the support column 21. The storage box 24 is fixedly installed on the support column 21. The storage box 24 is filled with insect attracting pheromones.
[0036] As Figure 2 、 Figure 4 、 Figure 6As shown, the capture unit 2 further includes a capture net 26, a vertical column 27, a motion sensor 28, a bent rod 29, a drive coil 210, a return spring 211, a pulling rope 212, a magnetic block 213, an electromagnet 214, a scraper 215 and an electric telescopic rod 216. The capture net 26 is fixedly connected to the vertical column 27. One end of the vertical column 27 is rotatably connected to the rain shelter 25, and the other end is rotatably connected to the mounting table 22. The motion sensor 28 is fixedly installed on the support column 21. One end of the bent rod 29 is fixedly connected to the mounting table 22, and the other end is slidably connected to the capture net 26. The drive coil 210 is evenly arranged on the bent rod 29. One end of the return spring 211 is fixedly connected to the mounting table 22, and the other end is fixedly connected to the capture net 26. The magnetic block 213 is slidably installed on the support column 21, and the magnetic block 213 is connected to the capture net 26 through the pulling rope 212. The electromagnet 214 is fixedly installed on the support column 21. The scraper 215 is slidably installed on the outer surface of the lighting lamp 23. A cleaning sponge is arranged inside the scraper 215. The scraper 215 is fixedly connected to the telescopic end of the electric telescopic rod 216. The fixed end of the electric telescopic rod 216 is fixedly installed at the bottom of the lighting lamp 23 through a connecting block. A conductive ring is arranged at the contact end of the capture net 26 and the bent rod 29, and the conductive ring of the capture net 26 is electrically connected to the electric telescopic rod 216.
[0037] When forest pests pass through the capture net 26 and enter the interior, the motion sensor 28 detects the generated motion and determines that the pests have entered the capture range. At this time, the motion sensor 28 feeds back to the controller, and the controller passes an electric current through the electromagnet 214, thereby pulling the magnetic block 213 to move upward along the support column 21. Under the action of the self-restoring force of the return spring 211, the capture net 26 is driven to pull the pulling rope 212 to rotate along the vertical column 27 and turn outward, so as to enclose the space and capture the pests inside. During the rotation of the capture net 26, it slides along the bent rod 29, so that the effective number of turns of the drive coil 210 gradually increases and the resistance gradually increases, and thus the current supplied to the electric telescopic rod 216 gradually decreases. At this time, the electric telescopic rod 216 contracts to drive the scraper 215 to clean the lighting lamp 23, avoiding that during the long-term use process, impurities left by pests on the lighting lamp 23 affect the lighting effect of the lighting lamp 23, thereby affecting the capture effect of phototactic pests.
[0038] As Figure 4 、 Figure 5 As shown, the capture unit 2 further includes a right-angle rod 217, a memory bimetal 218, a baffle 219, a fixed cylinder 220 and a conductive column 221. One end of the right-angle rod 217 is fixedly connected to the support column 21, and the other end is fixedly connected to the memory bimetal 218. The memory bimetal 218 is fixedly connected to the conductive column 221. The baffle 219 is slidably installed on one side of the storage box 24. The fixed cylinder 220 is fixedly installed on the extension part of the right-angle rod 217. A conductive sheet is arranged inside the fixed cylinder 220, and the conductive sheet is electrically connected to the lighting lamp 23.
[0039] As Figure 5 shown, the memory bimetal 218 is composed of two upper and lower memory metal sheets, and the deformation amount of the upper memory metal sheet is greater than that of the lower memory metal sheet.
[0040] During the day when the temperature is relatively high and it is necessary to clean the forest pests, the memory bimetal 218 bends upward under the influence of temperature, thereby driving the conductive column 221 to disengage from the fixed cylinder 220. During the process of the memory bimetal 218 bending upward, it pushes the baffle 219 to move upward along the storage box 24, thereby opening the storage box 24 to release the internal insect pheromone, thereby attracting the forest pests into the inside of the capture net 26 to complete the pest capture. At night when the temperature is relatively low, the memory bimetal 218 returns to its initial state. At this time, the conductive column 221 extends back into the fixed cylinder 220 and contacts the conductive sheet. At this time, the lighting lamp 23 is lit, and at this time, it attracts phototactic pests into the capture net 26 for capture, improving the continuous pest capture efficiency during the day and at night.
[0041] As Figure 3 、 Figure 7 、 Figure 8 shown, the disinfection and killing unit 3 includes a cylinder 31, an induction coil 32, a discharge plate 33, a buffer spring 34, a push plate 35 and a straight rod 36. One end of the cylinder 31 is fixedly connected to the mounting table 22, and the other end is fixedly connected to the fixed box 1. The induction coil 32 is fixedly installed inside the cylinder 31 at the end away from the fixed box 1. The discharge plate 33 is electrically connected to the induction coil 32. One end of the buffer spring 34 is fixedly connected to the inner wall of the cylinder 31, and the other end is fixedly connected to the discharge plate 33. The push plate 35 is fixedly installed at one end of the discharge plate 33 close to the fixed box 1. The discharge plate 33 abuts against the end of the straight rod 36 close to the horizontal base. The other end of the straight rod 36 is fixedly connected to the magnet 213. The cylinder 31 is fixedly connected to the collection unit 4.
[0042] When the pests enter the inside of the capture net 26, the controller controls the air extraction pump 47 to start, thereby sucking the pests into the inside of the cylinder 31. At the same time, since the magnet 213 moves upward and drives the straight rod 36 to move upward synchronously, at this time, the discharge plate 33 returns to the horizontal state under the action of the self-restoring force of the buffer spring 34. During the process of the magnet 213 moving upward in the induction coil 32, the magnetic flux changes, so that a current is generated in the induction coil 32 and transmitted to the discharge plate 33, causing the discharge plate 33 to discharge and electrocute and kill the pests. After the disinfection and killing is completed, after the motion sensor 28 detects no movement, the polarity is changed, thereby pushing the magnet 213 to move downward and pushing the discharge plate 33 to turn downward and open. At this time, the push plate 35 pushes the flip cover to open the channel of the fixed box 1, so that the pest corpses on the discharge plate 33 fall onto the flip plate 42 for collection.
[0043] As Figure 6 、 Figure 9As shown in the figure, the collection unit 4 includes a memory spring 41, a flip plate 42, a partition 43, a spring airbag 44, a jet box 45, a long rod 46, and an air pump 47. One end of the memory spring 41 is fixedly connected to the inside of the fixed box 1, and the other end is fixedly connected to the flip plate 42. The flip plate 42 is fixedly connected to the long rod 46. The partition 43 is arranged inside the fixed box 1. The spring airbag 44 is arranged below the partition 43. The upper part of the spring airbag 44 abuts against the flip plate 42. The spring airbag 44 is connected to the jet box 45 through a hose. The jet box 45 is fixedly installed inside the fixed box 1. The jet box 45 is located above the flip plate 42. The air pump 47 is conductively connected to the cylinder 31 through a pipeline. A gravity sensor is arranged below the flip plate 42. The spring airbag 44 is provided with an air inlet and an air outlet, and one-way valves are arranged inside both the air inlet and the air outlet.
[0044] When the pest corpses fall on the flip plate 42, the weight of the accumulated pests is detected by the gravity sensor. When a certain weight is reached, the gravity sensor feeds back to the controller, and thus the controller conveys an electric current to the memory spring 41. The memory spring 41 expands and elongates, so that the flip plate 42 rotates along the long rod 46, and the pest corpses on the flip plate 42 are dumped into another part of the space for unified collection. During the rotation of the flip plate 42, the gas compressed in the spring airbag 44 is ejected from the jet box 45, so as to quickly collect the pest corpses and prevent them from accumulating on the flip plate 42.
[0045] As Figure 8 shown, the push plate 35 abuts against the flip cover provided on the fixed box 1.
[0046] In order to isolate the disinfection unit 3 and the collection unit 4 by the flip cover when the air pump 47 is working, to prevent the air pump 47 from adsorbing the disinfected pest corpses in the collection unit 4 into the air pump 47 and causing blockage, which affects the disinfection of pests.
[0047] As Figure 6 shown, the end of the drive coil 210 close to the support column 21 is the current input end.
[0048] In order to make the capture net 26 slide along the curved rod 29 during the rotation process, so that the effective number of turns of the drive coil 210 gradually increases, the resistance gradually increases, and thus the current conveyed to the electric telescopic rod 216 gradually decreases. At this time, the electric telescopic rod 216 contracts to drive the scraper 215 to clean the lighting lamp 23, preventing pests from leaving impurities on the lighting lamp 23 during long-term use and affecting the lighting effect of the lighting lamp 23, thereby affecting the capture effect of phototactic pests.
[0049] The working principle of the present invention: When the forest pests pass through the capture net 26 and enter the interior, the motion sensor 28 detects the movement and determines that the pests have entered the capture range. At this time, the motion sensor 28 feeds back to the controller, and the controller supplies current to the electromagnet 214, thereby pulling the magnetic block 213 to move upward along the pillar 21, so that under the action of the restoring force of the reset spring 211 itself, the capture net 26 pulls the pull rope 212 to rotate along the column 27 and flip outward, thereby closing the space to capture the pests inside. During the rotation of the capture net 26, it slides along the bent rod 29, so that the effective number of turns of the drive coil 210 gradually increases, and the resistance gradually increases, so that the current delivered to the electric telescopic rod 216 gradually decreases. At this time, the electric telescopic rod 216 contracts to drive the scraper 215 to clean the lighting lamp 23, so as to avoid the pests leaving impurities on the lighting lamp 23 during long-term use, affecting the lighting effect of the lighting lamp 23, thereby affecting the capture effect of phototactic pests.
[0050] When the temperature is high during the day and it is necessary to clean up the forest pests, the memory bimetallic strip 218 is affected by the temperature and bends upward, thereby driving the conductive column 221 to separate from the fixed tube 220. During the upward bending process of the memory bimetallic strip 218, the baffle 219 is pushed to move upward along the storage box 24, thereby opening the storage box 24 to release the internal insect attractant pheromone, thereby attracting the forest pests into the capture net 26 to complete the pest capture. When the temperature is lower at night, the memory bimetallic strip 218 returns to its initial state. At this time, the conductive column 221 re-extends into the fixed tube 220 and contacts the conductive sheet. At this time, the lighting lamp 23 is turned on, and the phototactic pests are attracted to enter the capture net 26 for capture, thereby improving the efficiency of continuous pest capture during the day and at night.
[0051] When the pests enter the capture net 26, the controller controls the vacuum pump 47 to start, thereby sucking the pests into the cylinder 31. At the same time, the magnetic block 213 moves upward, driving the straight rod 36 to move upward synchronously. At this time, the discharge plate 33 is restored to a horizontal state under the action of the restoring force of the buffer spring 34. During the upward movement of the magnetic block 213 in the induction coil 32, the magnetic flux changes, thereby generating current in the induction coil 32 and transmitting it to the discharge plate 33, so that the discharge plate 33 discharges and kills the pests with electric shock. After the disinfecting is completed, the motion sensor 28 detects that no motion is generated, and changes its polarity, thereby pushing the magnetic block 213 to move downward and push the discharge plate 33 to flip down and open. At this time, the push plate 35 pushes the flip cover to open the channel of the fixed box 1, so that the dead bodies of the pests on the discharge plate 33 fall onto the flip plate 42 for collection.
[0052] When the pest corpses fall on the turning plate 42, the weight of the accumulated pests is detected by the gravity sensor. When a certain weight is reached, the gravity sensor feeds back to the controller, so that the controller conveys current to the memory spring 41. The memory spring 41 expands and elongates, so that the turning plate 42 rotates along the long rod 46, and the pest corpses on the turning plate 42 are dumped into another part of the space for unified collection. During the turning process of the turning plate 42, the gas in the compression spring airbag 44 is ejected from the jet box 45, so as to quickly collect the pest corpses and prevent them from accumulating on the turning plate 42.
