Description

Technical Field

[0001] This invention relates to the field of biological control technology for agricultural pests, specifically to an automatic quantitative drug delivery device for contact film-based pesticide application to parasitic wasps. Background Technology

[0002] In assessing the toxicity of insecticides to parasitic wasps and other natural enemy insects, the residual film method is a standard approach. The principle involves coating a measured amount of pesticide solution into a uniform film on the inner wall of a transparent tubular container. After the solvent evaporates, test insects are introduced, dying upon contact with the pesticide film through their legs. The lethal concentration and other toxicological parameters are then determined.

[0003] However, the traditional manual operation method has the following problems:

[0004] Manual addition of liquid makes it difficult to ensure that the volume is accurate and consistent each time. The force, speed and number of times of manual rolling vary from person to person, resulting in uneven drug film thickness and poor experimental repeatability.

[0005] A set of toxicity experiments involving multiple concentration gradients and multiple repetitions requires the preparation of dozens of drug-coated tubes, and manual operation has low throughput and is time-consuming.

[0006] While some automated devices exist for assisting in the preparation of drug films, most are general-purpose spin coating or spraying equipment, not specifically designed for the structural characteristics and experimental procedures of parasitic wasp virulence assay tubes. In practical use, these devices often require separate steps involving drug administration, film formation, and insect introduction at different equipment or workstations, resulting in fragmented operation processes. It is difficult to integrate the entire process from quantitative drug administration and rapid film drying to insect release into a single device. Summary of the Invention

[0007] The purpose of this invention is to provide an automated quantitative drug delivery device for parasitic wasp contact film method, in order to solve the problems of low precision and low throughput of manual operation in the prior art, as well as the inability of existing devices to integrate functions such as dedicated drug delivery for virulence assay tubes, rapid film formation and sequential release of test insects.

A protruding rod is fixedly connected to the inner wall of the positioning frame. The surface of the protruding rod and one end of the driving block are both tapered structures, so that when the central ring moves toward the end of the protruding rod, the protruding rod squeezes the driving block and causes the driving block to drive the gripper away from the central ring through the connecting rod, thereby releasing the clamping of the drug film tube.

[0021] Preferably, the first fixed plate, the second fixed plate, and the conveying plate are each provided with a movable groove in the middle of the corresponding gripper position, so that the central ring cooperates with the gripper to drive the drug film tube corresponding to the movable groove position to reciprocate within the positioning tube.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention uses a ring-shaped multi-station rotating and variable-speed linkage mechanism to precisely match the moving speed of the drug film tube with the atomization efficiency of the pneumatic ring nozzle, achieving precise control of the drug film thickness and uniform coating, significantly improving experimental repeatability. At the same time, the multi-station continuous flow operation greatly increases the throughput of drug film tube preparation, meeting the needs of large-scale toxicology experiments. Furthermore, it integrates the entire process of feeding, quantitative drug administration, hot gas-assisted rapid film formation, and automatic introduction of parasitic wasps into a single device, completely solving the problems of process fragmentation, low precision, and low efficiency in traditional manual operation and existing equipment.

[0027] 2. The present invention also utilizes the periodic change in the meshing state of the connecting gear with the first concave arc cone and the second concave arc cone to make the movement speed of the drug film tube monotonically increase, automatically generating a continuous drug film thickness gradient. This eliminates the need to manually prepare multiple concentrations to obtain multi-gradient toxicity test tubes, thereby comprehensively improving the efficiency, consistency and convenience of toxicity determination experiments.

[0046] 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.

[0047] Please see Figure 1-11 This invention provides a technical solution: an automatic quantitative drug delivery device for parasitic wasp contact film method, comprising:

[0048] Support frame 1, which is equipped with a feeding component, a metering component, a clamping component, a driving component, a bee storage component, and a drug delivery component;

[0049] The feeding assembly includes a first fixed plate 201 and a second fixed plate 202. A positioning tube 207 is fixedly disposed between the first fixed plate 201 and the second fixed plate 202. A conveying plate 204 is rotatably connected to both ends of the inner wall of the positioning tube 207. Multiple drug film tubes 206 are movably disposed circumferentially in the middle of the conveying plate 204. The first fixed plate 201 and the second fixed plate 202 are fixedly mounted on the top of the support frame 1 by a bracket. The two conveying plates 204 are fixedly mounted together by a connecting rod. Multiple open positioning grooves 205 are opened in the middle of the conveying plate 204, and the drug film tubes 206 are movably connected to the inner wall of the positioning grooves 205. The length is equal to the distance between the first fixed plate 201 and the second fixed plate 202. A fixed tube 203 is fixedly embedded in the middle of the first fixed plate 201 and the second fixed plate 202, and the conveying plate 204 is rotatably connected to the surface of the fixed tube 203 through a bearing. A feeding guide frame 208 and a discharging guide frame 209 are fixedly embedded between the first fixed plate 201 and the second fixed plate 202. The feeding guide frame 208 and the discharging guide frame 209 are both fixedly installed on the surface of the positioning tube 207. The side wall of the positioning tube 207 corresponding to the positions of the feeding guide frame 208 and the discharging guide frame 209 is provided with notches for the medicine film tube 206 to enter and exit.

[0050] In use, the above structure involves placing the drug film tubes 206 sequentially from the feed guide frame 208 into the positioning grooves 205 in the middle of the conveyor plate 204. The conveyor plate 204 is then driven to rotate on the inner wall of the positioning tube 207. The positioning tube 207 prevents the drug film tubes 206 from detaching from the positioning grooves 205. The positioning tube 207 is made of transparent material, allowing for easy observation of the drug film tubes 206. Each time the stepper motor is started, the conveyor plate 204 rotates at a fixed angle. With each rotation, the drug film tube 206 at the current station is replaced by the next drug film tube 206, achieving continuous automatic feeding of multiple drug film tubes 206.

[0051] The clamping assembly includes a central ring 401 and a gripper 404 movably arranged in a ring on the surface of the central ring 401. A connecting rod 403 is fixedly installed at one end of the gripper 404 corresponding to the position of the central ring 401. The connecting rod 403 movably passes through and extends to the inner wall of the central ring 401. A drive block 402 is fixedly installed at one end of the connecting rod 403 corresponding to the position of the inner wall of the central ring 401. A return spring 405 is fixedly installed between the gripper 404 and the central ring 401. A positioning frame 406 is fixedly installed at one end of the second fixing plate 202 corresponding to the position of the central ring 401. A protruding rod 407 is fixedly installed on the inner wall of the positioning frame 406. The surface of the protruding rod 407 and one end of the drive block 402 are both tapered structures, so that... When the central ring 401 moves toward one end of the protruding rod 407, the protruding rod 407 presses the driving block 402 and causes the driving block 402 to drive the gripper 404 away from the central ring 401 through the connecting rod 403, thereby releasing the gripping of the drug film tube 206. The first fixed plate 201, the second fixed plate 202 and the conveying plate 204 are respectively provided with movable grooves 408 in the middle of the corresponding positions of the gripper 404, so that the central ring 401 cooperates with the gripper 404 to drive the drug film tube 206 corresponding to the position of the movable groove 408 to reciprocate within the positioning tube 207. One end of the first fixed plate 201 corresponding to the position of the movable groove 408 is fixedly embedded with a guide tube 409 so that the drug film tube 206 moves stably on the inner wall of the guide tube 409.

[0052] When the above structure is in use, the central ring 401 drives the drive block 402 to separate from the protruding rod 407. Then, under the action of the return spring 405, the drive block 402 moves towards the center of the central ring 401. That is, the drive block 402 drives the gripper 404 to move closer to the center of the central ring 401 through the connecting rod 403 until the gripper 404 clamps the drug film tube 206. Conversely, the central ring 401 moves in the opposite direction, so that the protruding rod 407 is once again located on the inner wall of the central ring 401, and the protruding rod 407 squeezes the drive block 402. This causes the drive block 402 to drive the gripper 404 away from the central ring 401 through the connecting rod 403, thereby releasing the drug film tube 206.

[0053] The quantitative component includes a receiving box 301, which contains a one-way bending chain 303. One end of the chain 303 is fixedly installed at one end of a central ring 401. A sprocket 304 is rotatably connected to one end of the receiving box 301 so that when the sprocket 304 rotates, the chain 303 drives the corresponding drug film tube 206 to reciprocate axially through the central ring 401 and the gripper 404. The inner wall of the receiving box 301 has a receiving groove 302 for receiving the one-way bending chain 303. One end of the receiving groove 302 corresponding to the position of the clamping component passes through the receiving box 301. Protective shells 306 are fixedly installed at both ends of the receiving box 301. A first drive shaft 305 is rotatably connected to the middle of the protective shell 306 through a bearing. The receiving box 301 and the protective shell 306 are both fixedly installed on the inner wall of the conveying tray 204.

[0054] When the above structure is in use, the first drive shaft 305 drives the sprocket 304 to rotate, and the sprocket 304 drives the one-way bending chain 303 to drive the transmission, so that the one-way bending chain 303 extends out of the receiving box 301 from the inner wall of the receiving groove 302 and drives the central ring 401 to move. By controlling the rotation speed of the first drive shaft 305, the moving speed of the clamping assembly driving the drug film tube 206 can be controlled to achieve the purpose of quantitative drug administration.

[0055] The drive assembly includes a first concave arc cone 503 and a second concave arc cone 504 arranged at right angles. The drive assembly also includes a drive shaft 505 located within the angle between the first concave arc cone 503 and the second concave arc cone 504. A drive seat 506 is fixedly mounted on the surface of the drive shaft 505, and a plurality of connecting gears 507 are rotatably connected to the surface of the drive seat 506 via bearings. The connecting gears 507 mesh with the first concave arc cone 503 and the second concave arc cone 504 respectively. A face gear 508 is fixedly mounted on the bottom of the drive shaft 505, and a drive gear 510 meshes with the bottom of the face gear 508. A second drive shaft 509 is fixedly mounted on the middle of the drive gear 510. A drive gear 511 for driving the conveyor disc 204 to rotate is fixedly mounted on one end of the second drive shaft 509. A first drive shaft 305 is fixedly mounted on one end of the first concave arc cone 503, and the first drive shaft 305 is fixedly mounted on the middle of the sprocket 304.

[0056] The drive assembly also includes a drive housing 501. The first drive shaft 305 and the second drive shaft 509 are rotatably connected to the side wall of the drive housing 501 via bearings. One end of the first concave arc cone 503 and the second concave arc cone 504 at corresponding positions is rotatably connected to a cross support shaft 502, and the cross support shaft 502 is fixedly installed on the inner wall of the drive housing 501. The tooth surfaces of the first concave arc cone 503 and the second concave arc cone 504 are concave arc curves. A semi-circular structure is formed between the cross sections of the first concave arc cone 503 and the second concave arc cone 504, and the drive shaft 505 is located at the center position. One end of the conveyor disk 204 corresponding to the position of the drive gear 511 is provided with a drive tooth groove 512. The drive gear 511 movably passes through the second fixed disk 202 and meshes inside the drive tooth groove 512. The second concave arc cone 504 is driven by a drive motor, and the second drive shaft 509 is driven by a stepper motor.

[0057] In use, the stepper motor drives the second drive shaft 509 to rotate, causing the second drive shaft 509 to rotate the conveyor disc 204 on the inner wall of the positioning tube 207 via the drive gear 511 and drive tooth groove 512. When the second drive shaft 509 rotates a fixed number of times, it will cause the face gear 508 to rotate a fixed angle via the transmission gear 510. When the face gear 508 rotates a fixed angle, it will change the angle of the connecting gear 507 via the transmission shaft 505 and drive seat 506, and the meshing angle between the connecting gear 507 and the first concave arc cone 503 and the second concave arc cone 504 will change. Since the second concave arc cone 504 is driven by the drive motor, it serves as the main force. The first concave arc cone 503 is driven by the second concave arc cone 504 in conjunction with the connecting gear 507. The rotation is driven by the connecting gear 507. When the meshing state between the connecting gear 507 and the first concave arc cone 503 and the second concave arc cone 504 changes, the rotational speed of the second concave arc cone 504, driven by the connecting gear 507, changes. When the conveyor disk 204 rotates one revolution, one of the connecting gears 507 no longer meshes with the first concave arc cone 503 and the second concave arc cone 504 simultaneously. Instead, a new connecting gear 507 meshes with both the first and second concave arc cones simultaneously. This ensures that the rotation of the first concave arc cone 503 continuously increases or decreases during the rotation of the conveyor disk 204. After one cycle, it returns to its initial state. In other words, for every revolution of the conveyor disk 204, the connecting gear 507 completes one rotation, and after one cycle, it returns to its initial state.

[0058] The bee storage assembly includes a bee storage box 601 for delivering parasitic bees into the corresponding location of the medicine film tube 206;

[0059] The drug delivery assembly includes a pneumatic annular nozzle 704 for spraying liquid medicine into a drug film tube 206 delivered to the clamping assembly;

[0060] A bee storage box 601 is fixedly installed at one end of a first fixed plate 201. A first feed pipe 602 is fixedly installed on the top of the bee storage box 601. A connecting hole 603 is provided at the bottom of the bee storage box 601 and at one end opposite to the first fixed plate 201, so that the medicine film tube 206, when moved to the position of the connecting hole 603, communicates with the interior of the bee storage box 601. The drug delivery assembly also includes a liquid storage box 701, which is fixedly installed on the top of the support frame 1. The top of 701 is fixedly installed with a second feed pipe 702 and an air inlet pipe 703. The air inlet pipe 703 is connected to a hot air source and is used to provide hot air to the pneumatic annular nozzle 704. The pneumatic annular nozzle 704 is fixedly installed at the bottom of the liquid storage box 701. The liquid storage box 701 is used to provide liquid medicine to the pneumatic annular nozzle 704. The position of the pneumatic annular nozzle 704 corresponds to that of the guide pipe 409. The diameter of the pneumatic annular nozzle 704 is smaller than the inner diameter of the medicine film tube 206.

[0061] In use, the above structure continuously atomizes and sprays the drug through the pneumatic annular nozzle 704, coating the inner wall of the drug film tube 206 with the same atomization efficiency of the pneumatic annular nozzle 704. The faster the drug film tube 206 moves, the thinner the drug film formed; conversely, the slower the drug film tube 206 moves, the thicker the drug film formed by the pneumatic annular nozzle 704. By controlling the moving speed of the drug film tube 206, the purpose of quantitative drug administration is achieved. This means precisely matching the moving speed of the drug film tube 206 with the atomization efficiency of the pneumatic annular nozzle 704, thus achieving precise control of the drug film thickness. Controllable and uniform coating significantly improves experimental repeatability. Simultaneously, the air inlet pipe 703 is connected to a heat source to provide hot air to the pneumatic annular nozzle 704. This allows the pneumatic annular nozzle 704 to use hot air as a driving source, and the hot air carries the drug solution to coat the inner wall of the drug film tube 206. The hot air accelerates the evaporation of the solvent, which accelerates the formation of a uniform drug film on the inner wall of the drug film tube 206. When the delivery tray 204 moves the drug film tube 206 after it has been coated with the drug solution to the connecting hole 603, the parasitic wasps automatically enter the drug film tube 206 from the bee storage box 601 under negative pressure or phototaxis, thus completing the introduction of the test insects.

[0062] The feeding guide frame 208, guide tube 409, connecting hole 603 and discharging guide frame 209 are arranged in a clockwise rotation sequence, and the connecting hole 603 and guide tube 409 are located at the bottom of the first fixed plate 201, which facilitates the parasitic bees in the bee storage box 601 to enter the corresponding medicine film tube 206 through the connecting hole 603. At the same time, due to the influence of gravity, the unidirectional bending chain 303 bends in the upward direction. Under the action of vertical gravity, the unidirectional bending chain 303 will not bend during operation, thereby improving the stability of the device operation.

[0063] Working principle: In use, the invention first places the drug film tubes 206 from the position of the feeding guide frame 208 into the positioning groove 205 in the middle of the conveyor plate 204. Then the drive assembly starts to work. First, the stepper motor drives the second drive shaft 509 to rotate, and the second drive shaft 509 drives the conveyor plate 204 to rotate on the inner wall of the positioning tube 207 through the drive gear 511 and the drive tooth groove 512. The positioning tube 207 is used to prevent the drug film tubes 206 from falling out of the positioning groove 205. At the same time, the positioning tube 207 is made of transparent material, which makes it easy to observe the drug film tubes 206. Each time the stepper motor starts, the conveyor plate 204 rotates at a fixed angle. Each rotation replaces the drug film tube 206 at the current station with the next drug film tube 206, realizing the continuous automatic feeding of multiple drug film tubes 206.

[0064] During the intermittent operation of the stepper motor, i.e., during the intermittent rotation of the conveyor disk 204, the drive motor drives the first concave arc cone 503 to rotate clockwise via the second concave arc cone 504 and the connecting gear 507. This causes the first concave arc cone 503 to drive the first drive shaft 305 to rotate clockwise. Consequently, the first drive shaft 305 drives the sprocket 304 to rotate, which in turn drives the one-way bending chain 303. This causes the one-way bending chain 303 to extend out of the receiving box 301 from the inner wall of the receiving groove 302 and move the central ring 401. At this time, the central ring 401 moves towards the medicine film tube 206 corresponding to the position of the movable groove 408 in the second fixed disk 202. During this process, the central ring 401 causes the drive block 402 to separate from the protruding rod 407. Then, under the action of the return spring 405, the drive block 402 moves towards the center of the central ring 401. That is, the drive block 402, through the connecting rod 403, drives the gripper 404 to approach the center of the central ring 401 until the gripper 404 clamps the drug film tube 206. Under the continuous rotation of the sprocket 304, the unidirectional bending chain 303, through the central ring 401 and the gripper 404, drives the drug film tube 206 towards the guide tube 409 until one end of the drug film tube 206 contacts the end of the pneumatic annular nozzle 704. At this time, the drive motor rotates in the opposite direction. When the pneumatic annular nozzle 704 starts working, the reverse rotation of the drive motor causes the sprocket 304 to rotate in the opposite direction, and the one-way bending chain 303 to retract back into the inner wall of the receiving groove 302. Simultaneously, the one-way bending chain 303, through the central ring 401 and the gripper 404, drives the drug film tube 206 to move away from the pneumatic annular nozzle 704. During this process, the pneumatic annular nozzle 704 continuously atomizes and sprays the drug, coating the inner wall of the drug film tube 206. This continues until the drug film tube 206 is located between the first fixed plate 201 and the second fixed plate 202, and the protruding rod 407 returns to the inner wall of the central ring 401, causing the protruding rod 407 to... The squeezing drive block 402 causes the drive block 402 to drive the gripper 404 away from the central ring 401 via the connecting rod 403, thereby releasing the drug film tube 206. At this time, the pneumatic annular nozzle 704 stops working. The drug solution has been evenly coated on the inner wall of the drug film tube 206. Then, the conveying disc 204 moves the drug film tube 206 after being coated with the drug solution to the connecting hole 603. Under the influence of negative pressure or phototaxis, the parasitic wasps automatically enter the drug film tube 206 from the bee storage box 601 to complete the introduction of test insects. Subsequently, the conveying disc 204 continues to rotate, and the drug film tube 206 containing the parasitic wasps is sent to the discharge guide frame 209, where the operator can take it out for subsequent toxicity testing and observation.

[0065] During each drive cycle of the stepper motor, when the second drive shaft 509 rotates a fixed number of revolutions, it causes the face gear 508 to rotate by a fixed angle via the transmission gear 510. When the face gear 508 rotates by this fixed angle, it causes the angle of the connecting gear 507 to change via the transmission shaft 505 and the drive seat 506. This changes the meshing angle between the connecting gear 507 and the first concave arc cone 503 and the second concave arc cone 504. Since the second concave arc cone 504 is driven by the drive motor, it serves as the primary force. The first concave arc cone 503 is driven to rotate by the second concave arc cone 504 in conjunction with the connecting gear 507, serving as the secondary force. That is, when the connecting gear 507 meshes with the first concave arc cone 503... When the position of the meshing state between the second concave arc cone 504 changes, the rotational speed of the first concave arc cone 503 driven by the second concave arc cone 504 through the connecting gear 507 will change. When the conveyor disk 204 rotates once, one of the connecting gears 507 will no longer mesh with the first concave arc cone 503 and the second concave arc cone 504 at the same time, and a new connecting gear 507 will mesh with the first concave arc cone 503 and the second concave arc cone 504 at the same time. This makes the rotation of the first concave arc cone 503 continuously increase or decrease during the rotation of the conveyor disk 204. After one cycle, it will return to the initial state. That is, for every rotation of the conveyor disk 204, the connecting gear 507 completes one rotation, and after one cycle, it returns to the initial state.

[0066] Furthermore, when the conveyor disc 204 rotates, causing the rotational speed of the first concave arc cone 503 to increase, the rotational speed of the first drive shaft 305 will also increase. This will cause the rotational speed of the sprocket 304 driven by the first drive shaft 305 to also increase, meaning the speed of the unidirectional bending chain 303 will increase. Consequently, the speed at which the unidirectional bending chain 303 drives the drug film tube 206 through the central ring 401 in conjunction with the drive block 402 will also increase. Therefore, under the premise of the same atomization spraying efficiency of the pneumatic annular nozzle 704, the faster the drug film tube 206 moves, the thinner the drug film formed by the sprayed liquid; conversely, the slower the drug film tube 206 moves, the thicker the drug film formed by the liquid sprayed by the pneumatic annular nozzle 704. By controlling the moving speed of the drug film tube 206, the purpose of quantitative drug administration can be achieved. Simultaneously, quantitative drug administration is related to the rotation angle of the conveyor disc 204. Related to the number of sprayed drug film tubes 206, in one cycle, the drug film formed by the pneumatic annular nozzle 704 spraying the drug film inside the drug film tube 206 gradually becomes thinner, thus forming a concentration gradient, which is convenient for users to compare and observe. That is, by utilizing the periodic change of the meshing state of the connecting gear 507 with the first concave arc cone 503 and the second concave arc cone 504, the moving speed of the drug film tube 206 increases monotonically, automatically generating a continuous drug film thickness gradient. Multiple concentrations can be obtained without manually preparing multiple concentrations, thereby comprehensively improving the efficiency, consistency and convenience of toxicity determination experiments. Thus, in one rotation cycle of the conveyor plate 204, the inner wall of each drug film tube 206 can automatically form a precise concentration gradient from thick to thin (or vice versa), and multiple concentration gradient toxicity test samples can be obtained without changing parameters, realizing true quantitative drug administration.

[0067] The air inlet pipe 703 is connected to a hot air source to provide hot air to the pneumatic annular nozzle 704. This allows the pneumatic annular nozzle 704 to use hot air as a driving source and to carry the liquid medicine to coat the inner wall of the drug film tube 206. The hot air accelerates the evaporation of the solvent, which accelerates the formation of a uniform drug film on the inner wall of the drug film tube 206.
