Description

Technical Field

[0001] The present invention relates to the technical field of plant protection, and specifically to a detection device and method for the distribution density of alfalfa aphids. Background Art

[0002] Aphids are explosive pests, and the damage mainly occurs in the young stage of alfalfa plants. They gather in groups on various parts such as the tender stems, young buds, and flower organs of the plants. Visual detectors mainly use image processing and deep learning technologies to automatically identify and classify crop pest and disease images, so as to detect the insect density. This method has a high degree of automation and recognition accuracy, can process large-scale data sets, and is suitable for monitoring the insect density in large areas of farmland. However, the detection effect and applicability of visual detectors are limited by some factors: the recognition results of visual detectors may be affected by factors such as light and angle, resulting in unstable detection results. Chinese Patent Publication No.: CN221429980U discloses "Alfalfa Aphid Image Acquisition Device". In this patent, through the settings of a shooting box, an outer mesh surface, a driving shaft, a chain, and a yellow board body, the yellow board body can have an attracting effect on alfalfa aphids. The alfalfa aphids enter the interior of the shooting box through the outer mesh surface and are adsorbed onto the yellow board body under the attraction of the yellow board body. When the driving shaft rotates, it can drive the sprockets on the driving shaft and the driven shaft to rotate through the chain, so that the driven shaft rotates. Due to the overlapping relationship between the yellow board body and the driven shaft, the movement of the yellow board body can be driven, so that when the alfalfa aphids enter from the outer mesh surface and are adhered to the yellow board body, the insects can be evenly distributed on the yellow board body.

[0003] For the existing detection devices and methods for the distribution density of alfalfa aphids, due to the defects in the structural design, there are problems of how to detect the density of aphids on the surface of alfalfa plants and how to make the recognition results of visual detectors more accurate.

The opening and closing cover is controlled to move up and down through a hydraulic cylinder to extend the branches and leaves of alfalfa plants into the interior of the tank. When the opening and closing covers move away from each other, the electromagnet is powered off and the magnetic strip is separated from the electromagnet. When the opening and closing covers move closer to each other, the end surfaces of the two half worm gears coincide, the electromagnet is powered on, and the magnetic strip is tightly attached to the electromagnet by magnetic force.

[0013] Preferably, the flapping assembly includes a fixing body. The top of the fixing body is fixedly installed at the bottom of the half worm gear. A second motor is fixedly connected to the surface of the fixing body. The output end of the second motor is fixedly connected to a connecting column.

[0014] Preferably, the flapping assembly further includes an electromagnet. The electromagnet is fixedly installed on the surface of the connecting column. An arc-shaped plate is fixedly connected to the surface of the connecting column. The arc-shaped plate is made of rubber material.

[0015] Preferably, the number of both the flapping assembly and the driving assembly is set to two. A magnetic strip is fixedly connected to one end of the arc-shaped plate away from the connecting column. A plastic strip is fixedly connected to the inner side surface of the arc-shaped plate. The telescopic rod stably supports the movement of the opening and closing cover. When the opening and closing cover moves away, the two driving assemblies and the flapping assembly move away from each other. The rubber plate clamps the root position of the alfalfa plant. The screw rod drives the driving assembly to move downward, and the flapping assembly pats the branch and leaf position of the alfalfa plant. The aphids fall onto the top of the circular skin. The vibration assembly is driven by the telescopic motor to move upward close to the bottom of the circular skin, and the circular skin is in a vibrating state, so that the aphids on its top can be evenly distributed.

[0016] Preferably, the even distribution mechanism includes a support ring. The support ring is fixedly installed at the lower position of the inner side surface of the tank. A circular skin is fixedly connected to the surface of the support ring. The circular skin is made of a light-transmitting skin cloth material.

[0017] Preferably, the even distribution mechanism further includes a telescopic motor. The telescopic motor is fixedly installed at the middle position of the bottom of the tank. The output end of the telescopic motor is fixedly connected to a vibration assembly. An LED lamp is fixedly connected to the top of the vibration assembly. The circular skin is made of a semi-transparent latex white rubber material. The support ring fixes the edge of the circular skin. The telescopic motor can drive the rectangular shell to move up and down or rotate. When the rectangular shell moves upward, the surface of the sphere contacts the bottom of the circular skin. The vibrator drives the electric rope to vibrate, and the vibration of the electric rope causes the sphere to reciprocate in the inner side surface of the embedded spherical shell. The sphere transmits the vibration of the electric rope to the circular skin, and the aphids collected on the top of the circular skin are evenly dispersed under the vibration.

[0018] Preferably, the vibration assembly includes a connecting cylinder fixedly installed at the output end of the telescopic motor.

[0019] Preferably, the vibration assembly further includes an electric cord. The end face of the electric cord is fixedly installed at the output end of the vibrator. An embedded spherical shell is fixedly connected to the upper position of the inner side surface of the rectangular shell. A bottom hole is formed at the bottom of the embedded spherical shell, and a cut surface is formed at the top of the embedded spherical shell. A sphere is arranged on the inner side surface of the embedded spherical shell. Since the aphids have been killed, the aphids are more likely to break away from the surface of the alfalfa plants. The two semi-worm wheels are engaged, the rectangular hole is adapted to the rectangular block, the electromagnet is energized and attracted to the magnetic strip, and the rubber arc-shaped plate beats the positions of the branches and leaves of the alfalfa plants driven by the second motor. The plastic strips embedded in the arc-shaped plate increase the rigidity of the arc-shaped plate, so that the arc-shaped plate has a greater force when beating the plants, and at the same time, it does not prevent the arc-shaped plate from bending.

[0020] A method for detecting the distribution density of alfalfa aphids includes the following steps:

[0021] Step 1: Sealing. Randomly select an alfalfa plant, cut off the root of the alfalfa plant and place it upside down at the position of the opening and closing cover. At this time, the two opening and closing covers move away from each other, the screw rod slide drives the two hydraulic cylinders to move closer to each other, and the rubber plate clamps the root of the alfalfa plant. At this time, the branches and leaves of the alfalfa plant face downward and are opposite to the inner side surface of the tank body. The hydraulic cylinder drives the opening and closing cover to move downward, and the rotating cover is rotated to cover the position of the root of the alfalfa plant, so that the branches and leaves of the alfalfa plant can be in the sealed space between the tank body and the opening and closing cover;

[0022] Step 2: Killing aphids. The agent for killing aphids is atomized and sprayed into the tank body through the connecting pipe. After the aphids are killed, they are easily separated from the plant surface. The hoist drives the screw rod to rotate and move downward. The bottom end of the screw rod is connected to the cylindrical shell through a bearing. The rotation and downward movement of the screw rod are converted into the linear downward movement of the shell body, and the arc-shaped plate beats the positions of the branches and leaves of the plant, so that the aphids on the surface of the alfalfa plant can be quickly collected and detected;

[0023] Step 3: Beating the plant. The two semi-worm wheels are engaged, the rectangular hole is adapted to the rectangular block, the electromagnet is energized and attracted to the magnetic strip, and the rubber arc-shaped plate beats the positions of the branches and leaves of the alfalfa plant driven by the second motor. The plastic strips embedded in the arc-shaped plate increase the rigidity of the arc-shaped plate. The worm rotates driven by the driving motor, so that the semi-worm wheel rotates circumferentially on the inner side surface of the shell body. The semi-worm wheel drives the whole beating assembly to rotate circumferentially, and the positions of the branches and leaves of the alfalfa plant can be evenly beaten, and the aphid dropping rate is higher;

[0024] Step 4. Collection and detection: The aphids fall to the top of the circular skin. The vibration assembly is driven by the telescopic motor to move upward close to the bottom of the circular skin. The circular skin is in a vibrating state, so that the aphids on its top can be evenly distributed. After the plant is beaten for a certain time, the opening and closing covers move upward and separate from each other. The alfalfa plant is taken out. Subsequently, the opening and closing covers are reset and joined to the top of the tank body. The visual detector is placed at the middle position on the top of the opening and closing covers. The camera of the visual detector faces the top of the circular skin. The illumination of the LED lamp enables the visual detector to detect and count the aphids.

[0025] The present invention provides an alfalfa aphid distribution density detection device and method, which has the following beneficial effects:

[0026] 1. For the alfalfa aphid distribution density detection device and method, the rotating cover is rotated to cover the root position of the alfalfa plant, so that the branches and leaves of the alfalfa plant can be in the sealed space between the tank body and the opening and closing covers. The medicament for killing aphids is atomized and sprayed into the tank body through the connecting pipe. After the aphids are killed, they are easily separated from the surface of the plant. The hoist drives the screw to rotate and move downward, the driving assembly is driven to move downward, and the beating assembly beats the branches and leaves of the alfalfa plant. The aphids fall to the uniform mechanism, thereby detecting the aphid density on the surface of the alfalfa plant, and solving the problem of how to detect the density of aphids on the surface of the alfalfa plant.

[0027] 2. For the alfalfa aphid distribution density detection device and method, the second motor drives the connecting column to rotate reciprocally, and the arc plate is driven to swing around the connecting column. The arc plate beats the branches and leaves of the alfalfa plant reciprocally. The hoist drives the screw to rotate and move downward. The bottom end of the screw is connected to the cylindrical shell through a bearing. The rotational downward movement of the screw is converted into the linear downward movement of the shell. The arc plate beats the branches and leaves of the plant, so that the aphids on the surface of the alfalfa plant can be quickly collected and detected.

[0028] 3. For the alfalfa aphid distribution density detection device and method, after the plant is beaten for a certain time, the opening and closing covers move upward and separate from each other. The alfalfa plant is taken out. Subsequently, the opening and closing covers are reset and joined to the top of the tank body. The visual detector is placed at the middle position on the top of the opening and closing covers. The camera of the visual detector faces the top of the circular skin. The illumination of the LED lamp enables the visual detector to detect and count the aphids, and solves the problem of how to make the recognition result of the visual detector more accurate.

[0029] 4. For the alfalfa aphid distribution density detection device and method, when the telescopic motor drives the rectangular shell to rotate, the bottom of the circular skin is in uniform contact with the sphere. The distribution of aphids on the top of the circular skin is more uniform. The surface of the sphere is smooth and there is a certain gap between the spheres. When the sphere transmits the vibration to the circular skin, it is not easy to break the circular skin, making the visual detector more accurate when collecting visual images for counting.

[0030] 5. For the alfalfa aphid distribution density detection device and method, the worm rotates driven by the driving motor, causing the half worm gear to rotate circumferentially on the inner side surface of the housing. The half worm gear drives the whole beating assembly to rotate circumferentially, enabling the branches and leaves of the alfalfa plants to be evenly beaten, with a higher aphid dropping rate. The aphids fall onto the top of the circular leather. Due to the fixation of the support ring, the circular leather with tension is in a flat state when supporting the aphids. The circular leather enables the aphids to be evenly dispersed under the transmission of the sphere, and the detection accuracy of the visual detector is higher. Description of the Drawings

When the rectangular shell 942 moves upward, the surface of the sphere 948 contacts the bottom of the circular leather 92. The vibrator 943 drives the electric cord 944 to vibrate. The vibration of the electric cord 944 causes the sphere 948 to reciprocate inside the inner side of the embedded spherical shell 945. The sphere 948 transmits the vibration of the electric cord 944 to the circular leather 92. The aphids collected at the top of the circular leather 92 are evenly dispersed under the vibration. When the telescopic motor 93 drives the rectangular shell 942 to rotate, the bottom of the circular leather 92 contacts the sphere 948 evenly, and the distribution of aphids at the top of the circular leather 92 is more uniform. The surface of the sphere 948 is smooth and there is a certain gap between the spheres 948, so that when the sphere 948 transmits the vibration to the circular leather 92, it is not easy to break the circular leather 92. After the counting is completed, the first motor 3 drives the whole tank body 4 to rotate to clean the inner wall, making the visual detector more accurate when collecting visual images for counting.

The inner side of the cylindrical shell 673 is connected to the bottom end of the screw rod 65 through a bearing 66. The driving assembly 67 further includes a worm 674. The worm 674 is rotatably installed at a position near the edge of the inner side of the housing 671. A driving motor is fixedly connected to the housing 671 near the worm 674. The output end of the driving motor is fixedly connected to the end face of the worm 674. A semi-worm gear 675 is slidably connected to the inner side of the housing 671. A rectangular block 676 is fixedly connected to the end face of the semi-worm gear 675. A rectangular hole 677 is opened at one end of the semi-worm gear 675 away from the rectangular block 676;

[0059] The connecting cylinder 941 is fixedly installed at the output end of the telescopic motor 93. The surface of the connecting cylinder 941 is fixedly connected with a rectangular shell 942. The inner side of the connecting cylinder 941 is fixedly connected with a vibrator 943. The vibration assembly 94 further includes an electric cord 944. The end face of the electric cord 944 is fixedly installed at the output end of the vibrator 943. An embedded spherical shell 945 is fixedly connected to the upper position of the inner side of the rectangular shell 942. A bottom hole 947 is opened at the bottom of the embedded spherical shell 945. A cut surface 946 is opened at the top of the embedded spherical shell 945. A sphere 948 is arranged on the inner side of the embedded spherical shell 945.

[0060] During use, since the aphids have been treated with pesticides, it is easier for the aphids to detach from the surface of the alfalfa plants. The two semi-worm wheels 675 are engaged, the rectangular hole 677 is adapted to the rectangular block 676, the electromagnet 684 is energized and attracted to the magnetic strip 687. The arc-shaped plate 685 made of rubber pats the branches and leaves of the alfalfa plants under the drive of the second motor 682. The plastic strip 686 embedded inside the arc-shaped plate 685 increases the rigidity of the arc-shaped plate 685, making the arc-shaped plate 685 slap the plants with greater force while not preventing the bending of the arc-shaped plate 685. The worm 674 rotates under the drive of the drive motor, causing the semi-worm wheel 675 to rotate circumferentially on the inner side surface of the housing 671. The semi-worm wheel 675 drives the entire slapping assembly 68 to rotate circumferentially, enabling the branches and leaves of the alfalfa plants to be evenly slapped. The aphid dropping rate is higher. The aphids fall onto the top of the circular leather 92. Due to the fixation of the support ring 91, the circular leather 92 with tension is in a flat state when supporting the aphids. The circular leather 92 drives the aphids to be evenly dispersed under the transmission of the sphere 948, and the detection accuracy of the visual detector is higher.

[0061] Sixth Embodiment: As Figures 1-9 shown, a method for detecting the distribution density of alfalfa aphids includes the following steps:

[0062] Step 1: Sealing. Randomly select an alfalfa plant, cut off the root of the alfalfa plant and place it upside down at the position of the opening and closing cover 62. At this time, the two opening and closing covers 62 move away from each other, the screw rod slide 5 drives the two hydraulic cylinders 61 to move closer to each other, and the rubber plate 621 clamps the root of the alfalfa plant. At this time, the branches and leaves of the alfalfa plant face downward and are opposite to the inner side surface of the tank body 4. The hydraulic cylinder 61 drives the opening and closing cover 62 to move downward, and the rotating cover 8 is rotated to cover the root position of the alfalfa plant, so that the branches and leaves of the alfalfa plant can be in the sealed space between the tank body 4 and the opening and closing cover 62;

[0063] Step 2: Killing aphids. The pesticide for killing aphids is atomized and sprayed into the tank body 4 through the connecting pipe 7. After the aphids are killed, they are easily detached from the plant surface. The hoist 64 drives the screw rod 65 to rotate and move downward. The bottom end of the screw rod 65 is connected to the cylindrical shell 673 through the bearing 66. The rotational downward movement of the screw rod 65 is converted into the linear downward movement of the housing 671. The arc-shaped plate 685 pats the branches and leaves of the plant, enabling the aphids on the surface of the alfalfa plant to be quickly collected and detected;

[0064] Step 3: Pat the plant. The two half worm wheels 675 are engaged, the rectangular hole 677 is adapted to the rectangular block 676, the electromagnet 684 is energized and attracted to the magnetic strip 687. The arc-shaped plate 685 made of rubber pats the branches and leaves of the alfalfa plant under the drive of the second motor 682. The plastic strip 686 embedded inside the arc-shaped plate 685 increases the rigidity of the arc-shaped plate 685. The worm 674 rotates under the drive of the driving motor, causing the half worm wheel 675 to rotate circumferentially on the inner side surface of the housing 671. The half worm wheel 675 drives the whole beating assembly 68 to rotate circumferentially, and the branches and leaves of the alfalfa plant can be evenly patted, and the aphid dropping rate is higher.

[0065] Step 4: Collect and detect. The aphids fall onto the top of the circular leather 92. The vibration assembly 94 is driven by the telescopic motor 93 to move upward and close to the bottom of the circular leather 92. The circular leather 92 is in a vibrating state, so that the aphids on its top can be evenly distributed. After the plant is patted for a certain time, the opening and closing covers 62 move upward and separate from each other, and the alfalfa plant is taken out. Then the opening and closing covers 62 are reset and joined to the top of the tank body 4. The visual detector is placed at the middle position on the top of the opening and closing covers 62, and the camera of the visual detector is facing the top of the circular leather 92. The illumination of the LED lamp 95 enables the visual detector to detect and count the aphids.
