Description

Technical Field

[0001] The invention relates to the technical field of locust monitoring and trapping, and in particular to a mobile grassland locust monitoring and trapping device. Background Art

[0002] Locusts are an important part of the agricultural, forestry and animal husbandry ecosystem. Many harmful locust species cause varying degrees of damage to agriculture, forestry and animal husbandry. They use their chewing mouthparts to bite notches and holes in plant leaves and flower buds. In severe cases, they will eat up the leaves and flower buds of large areas of plants, causing major economic losses to agriculture, forestry and animal husbandry. The locusts that cause devastating disasters in agriculture are mainly migratory locusts. They have a wide distribution, a varied diet, fast reproduction, and strong resistance to adversity. They are difficult to prevent and control, especially in grassland environments. Affected by the temperature difference between morning and evening, locusts appear frequently in the morning and evening and will eat grassland crops. Therefore, it is necessary to monitor and trap grassland locusts.

[0003] Announcement No. 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, a second support leg is symmetrically and movably connected to the other side of the lower surface of the support plate, a first slide groove and a second slide groove are respectively provided on the upper surface and one side wall of the first support leg and the second support leg, and a first adjustment plate is slidably connected to the inner wall of the first slide groove. The grassland locust monitoring image acquisition device, through the setting of the limit rod and the limit hole, rotates the first knob to drive the limit rod to rotate out of the inner wall of the limit hole so that the connecting plate is no longer fixed on the support column, moves the connecting plate upward or downward to drive the first adjustment plate and the second adjustment plate on both sides to move up and down, and after adjusting to a suitable height, rotates the first knob in the opposite direction to drive the limit rod to rotate into the inner wall of the limit hole so as to limit and fix the height of the support plate, so as to facilitate the height adjustment of the device according to the terrain of the grassland, and thus convenient to use.

[0004] Announcement No. CN111480632A provides a locust monitoring trapping device and a method for using the same. The device comprises a detachably fixedly connected trapping part and a collecting part, wherein the trapping part emits a light beam of a specific wavelength to lure locusts; the collecting part is used to collect and monitor the number of trapped locusts and to power the entire device. The locust monitoring trapping device of the present invention is designed according to the living habits and phototaxis characteristics of locusts, thereby ensuring that locusts can more easily jump into the collecting part; in addition, the light source is set as a narrow wavelength focusing light source to emit a light beam, thereby avoiding the disadvantages of a wide wavelength light source attracting insects sensitive to other wavelengths and a point light source having a poor effect on attracting locusts, increasing the selectivity of the trapped insect species, avoiding the accidental killing of other beneficial insects or natural enemies, and improving the efficiency of locust trapping. At the same time, the device can accurately monitor the number and age of the trapped locusts, thereby facilitating the statistics, research and prevention of local locusts.

[0005] In the related technology, combining the above two existing technical solutions and mature technical solutions on the market, in the process of monitoring and trapping, the image acquisition terminals responsible for monitoring in the existing technology are mostly fixed working modes, which is not convenient for comprehensive and multi-range monitoring of locusts. Secondly, it is not conducive to use in harsh grassland environments. At the same time, locusts are mainly lured by drugs, which is not conducive to the development of green agriculture.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] A mobile grassland locust monitoring and trapping device

[0051] First embodiment:

[0052] See also Figures 1 to 11 , including a crawler vehicle 1, a monitoring mechanism 4, a suction pipe 5, a capture mechanism 6 and a capture net 13;

[0053] A bottom plate 2 is installed on the top of the crawler vehicle 1, and a mounting frame 3 is installed on one side of the bottom plate 2;

[0054] The monitoring mechanism 4 includes an image acquisition panel 44, a mounting box 41 is installed inside the mounting frame 3 by bolts, a flip motor 42 is installed on the inner bottom of the mounting box 41 by bolts, a driving pulley 43 is connected to the output shaft keyway of the flip motor 42, a notch 45 is opened inside the image acquisition panel 44, a driven pulley 46 is connected to the inner wall keyway of the notch 45, a belt 48 is sleeved on the outer wall of the driving pulley 43 and the driven pulley 46, and a grille plate 49 is embedded inside the attractant box 47;

[0055] See also Fig. 9 and Fig.11 : When monitoring locusts, the user needs to start the lamp 11, which generates light to lure the locusts, and then the user needs to completely expose the image acquisition panel 44 above the installation box 41. When the lured locusts are in the air, the image acquisition panel 44 can capture images of the locusts in the range, and can take pictures to store the image data. The monitoring personnel can view the monitoring images to determine the locust distribution density and locust species and sizes during the period;

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

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

[0058] The capture mechanism 6 includes a positioning frame 61 located on the upper and lower outer walls of the suction pipe 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 provided inside the limiting sleeve 62 and located on one side of the turntable 65, four inclined grooves 66 are provided inside the turntable 65, a guide wheel 67 is embedded inside each of the inclined grooves 66, a hook 68 is rotatably connected to the axis of each guide wheel 67, four slot plates 69 are fixedly provided on the outer wall of the limiting sleeve 62 and located outside the turntable 65, and a slider 610 is slidably connected inside each of the slot plates 69.

[0059] See also Figure 3 : During the process of monitoring locusts, the user can sample and trap the monitored locusts, and the capturing method requires operating the capturing mechanism 6.

[0060] See also Figure 4 and Figure 5 : When capturing, it is necessary to buckle the capturing net 13 on four hooks 68 to ensure that the capturing net 13 can be opened, so that when the lured locusts fly on the capturing net 13, the locusts can be stuck in time to achieve trapping, and then the monitoring personnel can collect the locust distribution sample of this period.

[0061] See also Figure 7 When the four hooks 68 are located at the bottom of the chute 66, the range of the four hooks 68 is the smallest, and a small-area capture net 13 can be hung for use.

[0062] See also Figure 8 : Rotate the turntable 65 counterclockwise at the position of the operating slot 64, and the four inclined slots 66 can rotate counterclockwise following the counterclockwise rotating turntable 65. During the rotation process, the inclined slots 66 can control the guide wheels 67 through the inner slots to drive the hooks 68 to move along the trajectory of the inclined slots 66 from the bottom to the top. During the movement, the hooks 68 move along the trajectory of the slot plate 69, so that the four hooks 68 can achieve a larger and extended range at the same time.

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

[0064] See also Fig. 9 and Fig.10 The reason why the side of the image acquisition panel 44 is set to be in an arc shape is to ensure that the image acquisition panel 44 avoids friction with the inner wall of the installation box 41 during the flipping process.

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

[0066] The cross section of each of the sliders 610 is a “T”-shaped structure, and each of the sliders 610 is fixedly connected to each of the hooks 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 can ensure 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 friction force with the inclined groove 66.

[0068] This embodiment: Compared with the traditional fixed image acquisition terminal design, this case is designed with an image acquisition panel 44 that can flip along the installation box 41, which can achieve 360-degree free flipping movement. When the image acquisition panel 44 is fully exposed, the monitoring angle can be changed, which is convenient for multi-range and multi-angle locust monitoring. Secondly, during periods when locusts are not active frequently, the image acquisition panel 44 can be completely hidden inside the installation box 41, which can be used for harsh grassland environments. At the same time, light trapping can reduce damage to the ecology and facilitate the sustainable development of green agriculture. Four inclined grooves 66 with the same slope are rotated to achieve four hooks 68 that can be linked and synchronized to complete the range change, which can be freely expanded and reduced. Such a design can be suitable for capture nets 13 of different sizes, and the capture net 13 can also be tightened, which is more conducive to the adhesion of locusts and convenient for trapping.

[0069] Second embodiment:

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

[0071] See also Fig.10 :This device has two working modes, one is the locust monitoring work in the first embodiment, and the second is the trapping and killing of locusts in batches. From the first embodiment, it can be seen that the image acquisition panel 44 can be rotated 360 degrees. When the locusts in the area are infested during this period, the user needs to rotate the image acquisition panel 44 to hide inside the installation box 41, then expose the food trap 47, and then remove the upper grille plate 49;

[0072] The user can place fermented wheat bran (the wheat bran is fried and then fermented with water to produce a sour smell that attracts locusts) in the attractant box 47 and also needs to start the light tube 11.

[0073] Also includes a driving mechanism 7;

[0074] An ultraviolet collecting barrel 8 and a strong suction fan 9 are respectively installed above the base plate 2, a negative pressure tube 10 is installed at the port of the strong suction fan 9, a negative pressure cylinder 16 is installed on the top of the ultraviolet collecting barrel 8, a vertical plate 14 is fixedly provided on the upper surface of the base plate 2 and located between the mounting frame 3 and the ultraviolet collecting barrel 8, a side plate 15 is fixedly provided on the outer wall of the vertical plate 14, the driving mechanism 7 includes a rotating motor 71 installed at the bottom of the side plate 15, the output shaft keyway of the rotating motor 71 is connected with a driving gear 72, a first bevel gear 73 is connected with a keyway at the top axis of the driving gear 72, one side of the first bevel gear 73 is meshedly connected with a second bevel gear 74, a rotating shaft 75 is connected with a keyway at the axis of the second bevel gear 74, a diffusion fan 76 is installed on the outer wall of the vertical plate 14 and located in the horizontal direction of the attractant box 47, a lamp tube 11 is installed on the outer wall of the suction pipe 5, and a gear ring 12 is fixedly provided on the outer wall of the suction pipe 5 and located below the lamp tube 11.

[0075] See also Fig.11 : The user starts the rotating motor 71 to control the driving gear 72 to rotate. When the driving gear 72 rotates, it can engage the transmission gear ring 12 to rotate. When the gear ring 12 rotates, it can control the suction pipe 5 to achieve rotational motion;

[0076] Then start the powerful suction fan 9 to form negative pressure suction in the negative pressure cylinder 16 through the negative pressure tube 10, so that the lured locusts will be sucked into the ultraviolet collection barrel 8 through the suction tube 5 for ultraviolet killing.

[0077] This embodiment: Compared with the traditional design, this case adds a batch killing function on the basis of the traditional detection and trapping. If a locust plague occurs, the user can completely hide the image acquisition panel 44 to expose the attractant box 47, and use light and smell to lure the plague locusts. Finally, the suction tube 5 can generate strong suction to suck in the lured locusts for killing, and the suction tube 5 adopts an automated self-rotation design, which can kill locusts in all directions, ensuring efficient killing, and can also lure in a variety of ways.

[0078] Third embodiment:

[0079] Please combine Fig.11 and Fig.12 The driving gear 72 and the gear ring 12 are meshed with each other, and the angle between the extended line of the axis of the first bevel gear 73 and the extended line of the axis of the second bevel gear 74 is ninety degrees.

[0080] The outer wall of the rotating shaft 75 is rotatably connected to the vertical plate 14 through a bearing, the output end of the rotating shaft 75 is key-connected to the diffusion fan 76 , and the outlet end of the negative pressure pipe 10 is sealed and installed with the negative pressure cylinder 16 .

[0081] See also Fig.11 During the operation of the second embodiment, when the suction tube 5 rotates to suck in locusts, the driving gear 72 will control the rotation of the first bevel gear 73. When the first bevel gear 73 rotates, it can engage the second bevel gear 74 on the transmission side to rotate. When the second bevel gear 74 rotates, it will drive the rotating shaft 75 to rotate. When the rotating shaft 75 rotates, it can link the diffusion fan 76 to rotate. The rotation of the diffusion fan 76 can accelerate the air circulation on the attractant 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. A plurality of balls 19 equidistantly distributed in an annular manner are installed inside the connecting sleeve 17 and around the axis of the connecting sleeve 17.

[0083] The upper surface of the ball 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 a "U"-shaped structure, and the cross section of the receiving sleeve 18 is a "Z"-shaped structure.

[0084] See also Fig.12 : The suction tube 5 rotates along the axial trajectory of the negative pressure cylinder 16, and the receiving sleeve 18 rotates on the ball 19 during the rotation. The rolling of the ball 19 can eliminate the rotation friction of the suction tube 5, ensuring that the suction tube 5 rotates more smoothly and stably. Secondly, it can also ensure that the suction tube 5 can achieve vacuum suction of locusts during the rotation process.

[0085] This embodiment: Compared with the traditional design, in the process of the suction pipe 5 rotating to suck and kill locusts, the first bevel gear 73 and the second bevel gear 74 that are exchanged by 90 degrees can be linked to control the diffusion fan 76 to rotate and accelerate the air circulation on the attractant box 47. This design can accelerate the diffusion of the sour gas generated by the attractant box 47, thereby diffusing the gas range that attracts locusts, and can attract more locusts. Especially in the case of locust disasters, it can kill and attract them efficiently.

[0086] Please refer to Figures 1 to 12 The working principle of a 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 the monitoring and collection of locusts, and the second is the trapping and killing of locusts in batches. The working process is to monitor and collect first, and if the number of locusts is large, trapping and killing are required;

[0088] Locust monitoring and collection work:

[0089] Grassland locusts are mainly active in the morning and evening, so users can monitor and trap grassland locusts in the morning and evening. There are two ways to monitor and trap them:

[0090] A crawler vehicle 1 can be placed directly outside a farmer's house for monitoring, or it can be placed in a grassland monitoring station. In this way, the entire device can be powered directly by indoor power supply, which is generally applicable to this placement method;

[0091] The second method is to move the operating crawler 1 to transport the device to a place where specific detection and monitoring is required, such as a field environment. If mobile monitoring is required, it is necessary to install external equipment such as batteries or solar panels in the mounting frame 3 to power the device. It should be noted that the second method is generally used in the high incidence period of locusts;

[0092] When monitoring locusts, the user needs to start the lamp 11, which generates light to lure the locusts. Then the user needs to completely expose the image acquisition panel 44 above the installation box 41. When the lured locusts are in the air, the image acquisition panel 44 can capture images of the locusts in the range, and can take pictures to store the image data. The monitoring personnel can view the monitoring images to determine the locust distribution density, locust species and sizes, etc. during the period.

[0093] A capture net 13 can be hung on the four hooks 68 to capture the lured locusts. By rotating the turntable 65 counterclockwise at the position of the operating slot 64, the four inclined slots 66 can rotate counterclockwise following the counterclockwise rotating turntable 65. During the rotation, the inclined slots 66 can control the guide wheels 67 through the inner slots to drive the hooks 68 to move along the trajectory of the inclined slots 66 from the bottom to the top. The hooks 68 move along the trajectory of the slot plate 69 during the movement, so that the four hooks 68 can achieve a larger and extended range at the same time.

[0094] Step S2:

[0095] Locust luring and killing work:

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

[0097] The user can place fermented wheat bran (after the wheat bran is fried and then fermented with water to produce a sour taste that attracts locusts) in the attractant box 47 and also needs to start the lamp 11;

[0098] The rotating motor 71 controls the driving gear 72 to rotate. When the driving gear 72 rotates, it can engage the transmission gear ring 12 to rotate. When the gear ring 12 rotates, it can control the suction pipe 5 to achieve rotational motion.

[0099] Then start the strong suction fan 9 to form negative pressure suction in the negative pressure cylinder 16 through the negative pressure pipe 10, so that the lured locusts will be sucked into the ultraviolet collection barrel 8 through the suction pipe 5 for ultraviolet killing;

[0100] When the suction tube 5 rotates to suck in locusts, the driving gear 72 will control the rotation of the first bevel gear 73. When the first bevel gear 73 rotates, it can engage the second bevel gear 74 on the transmission side to rotate. When the second bevel gear 74 rotates, it will drive the rotating shaft 75 to rotate. When the rotating shaft 75 rotates, it can link the diffusion fan 76 to rotate. The rotation of the diffusion fan 76 can accelerate the air circulation on the attractant box 47 to diffuse the gas.

[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 changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
