Description

Technical Field

[0001] This invention relates to the field of locust monitoring and trapping technology, and in particular to a mobile grassland locust monitoring and trapping device. Background Technology

[0002] Locusts are an important part of agricultural, forestry, and pastoral ecosystems. Many harmful locust species cause varying degrees of damage to agriculture, forestry, and animal husbandry. They use their chewing mouthparts to bite and eat plant leaves and buds, creating notches and holes. In severe cases, they can devour large areas of plant leaves and buds, causing significant economic losses to agriculture, forestry, and animal husbandry. The locusts that cause devastating disasters in agriculture are mainly migratory locusts. They are widely distributed, have a diverse diet, reproduce rapidly, and are highly resistant to adverse conditions, making them difficult to control. Especially in grassland environments, affected by the temperature difference between day and night, locusts appear frequently in the morning and evening and will graze on grassland crops. Therefore, it is necessary to monitor and trap grassland locusts.

[0003] CN221825082U discloses a grassland locust monitoring image acquisition device, including a support plate. A first support leg is symmetrically and movably connected to one side of the lower surface of the support plate, and a second support leg is symmetrically and movably connected to the other side of the lower surface of the support plate. A first groove and a second groove are respectively formed on the upper surface and one sidewall of the first and second support legs. A first adjusting plate is slidably connected to the inner wall of the first groove. This grassland locust monitoring image acquisition device, through the setting of a limiting rod and a limiting hole, allows the limiting rod to rotate out of the inner wall of the limiting hole when the first knob is rotated, thus freeing the connecting plate from being fixed to the support column. Moving the connecting plate up or down causes the first and second adjusting plates on both sides to move up and down. After adjusting to a suitable height, rotating the first knob in the opposite direction causes the limiting rod to rotate into the inner wall of the limiting hole, thereby limiting and fixing the height of the support plate. This facilitates adjustment of the device height according to the terrain of the grassland, making it convenient to use.

[0004] CN111480632A, a publication number, discloses a locust monitoring and trapping device and its usage method. It includes a detachably and fixedly connected trapping section and a collection section. The trapping section emits a light beam of a specific wavelength to attract locusts; the collection section collects and monitors the number of trapped locusts and provides power to the entire device. The locust monitoring and trapping device of this invention is designed based on the locusts' living habits and phototaxis, ensuring that locusts more easily jump into the collection section. Furthermore, by setting the light source to a narrow-wavelength focused light source to emit a light beam, it avoids the disadvantages of wide-wavelength light sources attracting insects sensitive to other wavelengths and the poor trapping effect of point light sources on locusts. This increases the selectivity of the insect species trapped, avoids accidental killing of other beneficial insects or natural enemies, and improves the locust trapping efficiency. Simultaneously, the device can accurately monitor the number and age of the trapped locusts, thus facilitating the statistics, research, and control of local locust populations.

[0005] In the relevant technologies, combining the two existing technical solutions mentioned above and mature technical solutions on the market, the existing technologies, in the process of monitoring and trapping, mostly use fixed image acquisition terminals, which is inconvenient for comprehensive and multi-range monitoring of locusts. Secondly, they are not suitable for use in harsh grassland environments. At the same time, the main method of attracting locusts is still through drug attraction, which is not conducive to the development of green agriculture. Furthermore, it is inconvenient for users to adjust the range of different sized trapping nets.

A vertical plate is fixed on the upper surface of the base plate between the mounting frame and the UV collection bucket. A side plate is fixed on the outer wall of the vertical plate. The driving mechanism includes a rotary motor installed at the bottom of the side plate. A drive gear is connected to the output shaft of the rotary motor via a keyway. A first helical gear is connected to the top shaft of the drive gear via a keyway. A second helical gear is meshed with one side of the first helical gear. A rotating shaft is connected to the shaft of the second helical gear via a keyway. A diffusion fan is installed on the outer wall of the vertical plate in the horizontal direction of the feeding box. A lamp tube is installed on the outer wall of the suction pipe.

When the image acquisition panel is fully exposed, the monitoring angle can be changed, facilitating multi-range and multi-angle locust monitoring. Furthermore, during periods when locust activity is infrequent, the image acquisition panel can be completely concealed inside the mounting box, making it suitable for harsh grassland environments. Additionally, light-based trapping reduces ecological damage, promoting sustainable green agriculture. The design utilizes four equally angled rotating grooves to allow four hooks to move in tandem, synchronously changing the range of the trap. This allows for flexible expansion and contraction, accommodating different sizes of trap nets and enabling the nets to be tightened, further promoting locust adhesion and trapping.

[0049] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] A mobile monitoring and trapping device for grassland locusts

[0051] First embodiment:

[0052] Please see Figures 1 to 11 It includes a tracked vehicle 1, a monitoring mechanism 4, an intake pipe 5, a capture mechanism 6, and a capture net 13;

[0053] The tracked vehicle 1 has a base plate 2 installed on its top, and a mounting bracket 3 is installed on one side of the base plate 2;

[0054] The monitoring mechanism 4 includes an image acquisition panel 44. The mounting box 41 is bolted to the inside of the mounting frame 3. A flip motor 42 is bolted to the bottom of the mounting box 41. The output shaft of the flip motor 42 is keyway connected to a drive pulley 43. The image acquisition panel 44 has a slot 45 inside. The inner wall of the slot 45 is keyway connected to a driven pulley 46. A belt 48 is fitted on the outer wall of the drive pulley 43 and the driven pulley 46. A grid plate 49 is embedded inside the bait box 47.

[0055] Please see Figure 9 and Figure 11 When monitoring locusts, the user needs to turn on the lamp tube 11. The lamp tube 11 produces light to attract locusts. Then, the user needs to fully expose the image acquisition panel 44 above the installation box 41. When the attracted locusts are in the air, the image acquisition panel 44 can acquire images of the locusts in that area and store the image data. The monitoring personnel can view the monitoring images to determine the locust distribution density and the type and size of the locusts during that period.

[0056] Secondly, during actual use, the user can start the flip motor 42 to drive the drive pulley 43 to rotate. When the drive pulley 43 rotates, the driven pulley 46 can be controlled by the belt 48 to control the entire image acquisition panel 44 to rotate clockwise or counterclockwise along the rotation connection of the mounting box 41. When flipping, the angle of the image acquisition panel 44 can be changed.

[0057] Preferably, the lamp tube 11 can be a black light lamp, an ultraviolet lamp, or a high-intensity incandescent lamp (wavelength 300-400nm is the best).

[0058] The capturing mechanism 6 includes a positioning frame 61 located on the upper and lower outer walls of the suction tube 5. A limiting sleeve 62 is fixedly provided on the outer wall of the positioning frame 61. A fastening bolt 63 is threadedly connected to the top of the limiting sleeve 62. A turntable 65 is rotatably connected inside the limiting sleeve 62. An operating groove 64 is opened inside the limiting sleeve 62 and on one side of the turntable 65. Four inclined grooves 66 are opened inside the turntable 65. A guide wheel 67 is embedded inside each inclined groove 66. A hook 68 is rotatably connected to the axis of each guide wheel 67. Four slotted plates 69 are fixedly provided on the outer wall of the limiting sleeve 62 and outside the turntable 65. A slider 610 is slidably connected inside each slotted plate 69.

[0059] Please see Figure 3 During the locust monitoring process, users can sample and trap the locusts. The trapping method requires operating the trapping mechanism.

[0060] Please see Figure 4 and Figure 5 When capturing locusts, the net 13 needs to be attached to the four hooks 68 to ensure that the net 13 can be opened. This way, when the locusts fly into the net 13, they can be caught in time to trap them. Then, the monitoring personnel can collect locust distribution samples for that period of time.

[0061] Please see Figure 7 When the four hooks 68 are located at the bottom of the inclined groove 66, the range of the four hooks 68 is the smallest, and a small area of ​​the capture net 13 can be used to hang it.

[0062] Please see Figure 8 Rotating the turntable 65 counterclockwise at the position of the operating slot 64 causes the four inclined slots 66 to rotate counterclockwise along with the turntable 65. During the rotation, the inclined slots 66 can be controlled by the inner slot to drive each guide wheel 67 to move each hook 68 along the trajectory of the inclined slot 66 from the bottom to the top. During the movement, the hooks 68 move along the trajectory of the slot plate 69, thus enabling the four hooks 68 to simultaneously expand their range.

[0063] Both ends of the image acquisition panel 44 in the horizontal direction are rotatably connected to the inner wall of the mounting box 41 through bearings, and both the front and rear sides of the image acquisition panel 44 are arc-shaped cut surfaces.

[0064] Please see Figure 9 and Figure 10 The reason why the sides of the image acquisition panel 44 are set in an arc shape is to ensure that the image acquisition panel 44 avoids friction with the inner wall of the mounting box 41 during the flipping process.

[0065] The four groove plates 69 are equidistantly distributed in a ring about the axis of the turntable 65, and the outer wall of each guide wheel 67 is in contact with the inner wall of each inclined groove 66.

[0066] Each slider 610 has a "T" shaped cross-section, and each slider 610 is fixedly connected to each hook 68.

[0067] Understandable: From Figure 5 and Figure 6 It can be seen that the slider 610 slides inside the groove plate 69. The "T"-shaped design ensures that the slider 610 can only move inside the groove plate 69. Secondly, the guide wheel 67 can preferably be made of rubber material, which can reduce the frictional force with the inclined groove 66.

[0068] In this embodiment, compared to the traditional fixed image acquisition terminal design, an image acquisition panel 44 that can rotate along the mounting box 41 is designed to achieve a 360-degree free rotation. When the image acquisition panel 44 is fully exposed, the monitoring angle can be changed, facilitating multi-range and multi-angle locust monitoring. Secondly, during periods when locust activity is infrequent, the image acquisition panel 44 can be completely hidden inside the mounting box 41, which is suitable for harsh grassland environments. At the same time, light trapping can reduce ecological damage and facilitate sustainable green agriculture. The use of four inclined grooves 66 with the same slope allows the four hooks 68 to rotate synchronously and change their range, freely expanding and shrinking. This design can be used with different sizes of trapping nets 13 and can also tighten the trapping nets 13, which is more conducive to locust adhesion and easier trapping.

[0069] Second embodiment:

[0070] Please see Figure 1 , Figure 2 , Figure 10 and Figure 11 The outer wall of the feeding box 47 and the outer wall of the grid plate 49 are interference fit, and the four inclined grooves 66 are equidistantly distributed in a ring about the axis of the turntable 65.

[0071] Please see Figure 10 This device has two working modes. One is the locust monitoring work in the first embodiment, and the other is the mass trapping and extermination of locusts. As can be seen from the first embodiment, the image acquisition panel 44 can be rotated 360 degrees. When the locusts in the area are rampant at that time, the user needs to rotate the image acquisition panel 44 to hide inside the installation box 41, then expose the bait box 47, and then remove the upper grid plate 49.

[0072] Users can place fermented wheat bran (wheat bran is stir-fried and then fermented with water to produce a sour smell that attracts locusts) in the bait box 47, and also need to turn on the light tube 11.

[0073] It also includes the drive mechanism 7;

[0074] An ultraviolet collection tank 8 and a powerful suction fan 9 are respectively installed on the top of the base plate 2. A negative pressure pipe 10 is installed at the port of the powerful suction fan 9. A negative pressure cylinder 16 is installed on the top of the ultraviolet collection tank 8. A vertical plate 14 is fixed on the upper surface of the base plate 2 between the mounting frame 3 and the ultraviolet collection tank 8. A side plate 15 is fixed on the outer wall of the vertical plate 14. The drive mechanism 7 includes a rotary motor 71 installed at the bottom of the side plate 15. The output shaft of the rotary motor 71 is keyway connected to a drive gear 72. A first helical gear 73 is keyway connected at the top axis of the drive gear 72. A second helical gear 74 is meshed on one side of the first helical gear 73. A rotating shaft 75 is keyway connected at the axis of the second helical gear 74. A diffusion fan 76 is installed on the outer wall of the vertical plate 14 in the horizontal direction of the feeding box 47. A lamp tube 11 is installed on the outer wall of the suction pipe 5. A toothed ring 12 is fixed on the outer wall of the suction pipe 5 below the lamp tube 11.

[0075] Please see Figure 11 The user starts the rotary motor 71 to control the drive gear 72 to rotate. When the drive gear 72 rotates, it can mesh with the transmission gear ring 12 to rotate. When the gear ring 12 rotates, it can control the suction pipe 5 to achieve rotational movement.

[0076] Then, the powerful suction fan 9 is activated, which creates a negative pressure suction in the negative pressure cylinder 16 through the negative pressure pipe 10. This attracts locusts, which are then sucked into the ultraviolet collection bucket 8 through the suction pipe 5 for ultraviolet sterilization.

[0077] In this embodiment, compared to the traditional design, this design adds a mass extermination function to the traditional detection and trapping method. If a locust plague occurs, the user can completely hide the image acquisition panel 44, exposing the bait box 47. Light and scent are used to lure the locusts. Finally, the suction tube 5 generates a strong suction to suck in and kill the lured locusts. The suction tube 5 adopts an automated rotation design, which can kill locusts from all directions, ensuring efficient extermination. Multiple methods of luring are also available.

[0078] Third embodiment:

[0079] Please combine Figure 11 and Figure 12 The drive gear 72 and the gear ring 12 mesh with each other, and the angle between the extended axis of the first helical gear 73 and the extended axis of the second helical gear 74 is ninety degrees.

[0080] The outer wall of the rotating shaft 75 is rotatably connected to the vertical plate 14 via a bearing. The output end of the rotating shaft 75 is connected to the diffuser fan 76 via a keyway. The outlet end of the negative pressure pipe 10 is sealed to the negative pressure cylinder 16.

[0081] Please see Figure 11 In the second embodiment, when the suction tube 5 rotates to suck up locusts, the drive gear 72 will control the first helical gear 73 to rotate. When the first helical gear 73 rotates, it can mesh with the second helical gear 74 on the transmission side to rotate. When the second helical gear 74 rotates, it will drive the rotating shaft 75 to rotate. When the rotating shaft 75 rotates, it can drive the diffusion fan 76 to rotate. The rotation of the diffusion fan 76 can accelerate the air circulation on the feeding box 47.

[0082] The outer wall of the negative pressure cylinder 16 is integrally provided with a connecting sleeve 17, and the bottom end of the suction pipe 5 is integrally provided with a receiving sleeve 18. Inside the connecting sleeve 17 and around the axis of the connecting sleeve 17, a plurality of balls 19 are installed in an equidistant ring.

[0083] The upper surface of the ball bearing 19 and the lower surface of the receiving sleeve 18 are in contact with each other. The cross-section of the connecting sleeve 17 is U-shaped, and the cross-section of the receiving sleeve 18 is Z-shaped.

[0084] Please see Figure 12 The suction pipe 5 rotates along the axis of the negative pressure cylinder 16, and during the rotation, the receiving sleeve 18 rotates on the ball 19. The rolling of the ball 19 can eliminate the rotational friction of the suction pipe 5, ensuring that the suction pipe 5 rotates more smoothly and stably. Secondly, it can also ensure that the suction pipe 5 can achieve vacuum suction of locusts during the rotation.

[0085] In this embodiment, compared to the traditional design, the first helical gear 73 and the second helical gear 74, which rotate 90 degrees, can be linked to control the diffusion fan 76 to rotate and accelerate the air circulation on the bait box 47 during the process of the suction pipe 5 rotating to kill locusts. This design can accelerate the diffusion of the acidic gas generated by the bait box 47, thereby expanding the range of gas that attracts locusts and attracting more locusts. Especially in the case of locust plagues, it can effectively kill and attract locusts.

[0086] Please refer to the following: Figures 1 to 12 The working principle of the mobile grassland locust monitoring and trapping device provided by the present invention is as follows:

[0087] Step S1: This device has two working modes. One is locust monitoring and collection, and the other is locust trapping and killing in batches. The working process is to first monitor and collect, and if there are many locusts, trapping and killing will be necessary.

[0088] Locust monitoring and data collection:

[0089] Grassland locusts are mainly active in the morning and evening, so users can monitor and trap grassland locusts during these two time periods. There are two methods for monitoring and trapping them.

[0090] One method is to place the tracked vehicle 1 directly outside a farmer's house for monitoring, or it can be placed inside a grassland monitoring station. This allows the entire device to be powered directly by indoor power supply, and this placement method is commonly used.

[0091] The second method involves moving the tracked vehicle 1 to transport the device to a specific location requiring monitoring, such as a field. If mobile monitoring is required, external equipment such as batteries or solar panels need to be installed in the mounting frame 3 to power the device. It should be noted that the second method is generally used during the peak locust season.

[0092] When monitoring locusts, the user needs to turn on the lamp tube 11. The lamp tube 11 produces light to attract locusts. Then, the user needs to fully expose the image acquisition panel 44 above the installation box 41. When the attracted locusts are in the air, the image acquisition panel 44 can acquire images of the locusts in that area and store the image data. The monitoring personnel can view the monitoring images to determine the locust distribution density and the type and size of the locusts during that period.

[0093] A net 13 can be suspended on the four hooks 68 to catch the attracted locusts. By rotating the turntable 65 counterclockwise at the position of the operating groove 64, the four inclined grooves 66 can rotate counterclockwise along with the turntable 65. During the rotation of the inclined grooves 66, the guide wheels 67 can be controlled by the inner groove to drive each hook 68 to move from the bottom to the top along the trajectory of the inclined groove 66. During the movement, the hooks 68 move along the trajectory of the groove plate 69, so that the range of the four hooks 68 can be expanded at the same time.

[0094] Step S2:

[0095] Locust trapping and extermination efforts:

[0096] The rotating image acquisition panel 44 is hidden inside the mounting box 41, then the feeding box 47 is exposed, and then the upper grid plate 49 is removed;

[0097] Users can place fermented wheat bran (wheat bran is stir-fried and then fermented with water to produce a sour smell that attracts locusts) in the bait box 47, and also need to turn on the light tube 11.

[0098] The rotary motor 71 controls the drive gear 72 to rotate. When the drive gear 72 rotates, it can mesh with the transmission gear ring 12 to rotate. When the gear ring 12 rotates, it can control the suction pipe 5 to achieve rotational movement.

[0099] Then, the powerful suction fan 9 is activated, and negative pressure suction is formed in the negative pressure cylinder 16 through the negative pressure pipe 10. In this way, the locusts attracted will be sucked into the ultraviolet collection bucket 8 through the suction pipe 5 for ultraviolet sterilization.

[0100] When the suction tube 5 rotates to suck up locusts, the drive gear 72 will control the first helical gear 73 to rotate. When the first helical gear 73 rotates, it can mesh with the second helical gear 74 on the transmission side to rotate. When the second helical gear 74 rotates, it will drive the rotating shaft 75 to rotate. When the rotating shaft 75 rotates, it can drive the diffusion fan 76 to rotate. The rotation of the diffusion fan 76 can accelerate the air circulation and diffusion of gas on the feeding box 47.

[0101] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
