Description

Technical Field

[0001] The utility model belongs to the field of biological control, and particularly relates to a dart bee release device and a drone. Background Art

[0002] Biological control is a plant protection method that exploits the mutual checks and balances between organisms to achieve pest control. It is an important means of controlling farmland pests and diseases. From a long-term perspective, biological control technology can effectively avoid a series of problems caused by chemical control, such as the development and increase of resistance levels, pesticide residues, and environmental issues, providing an eco-friendly alternative for pest and disease control. Biological control technology has the advantages of low cost, sustainability, ecological improvement, and no pollution or harm. It is of great significance to reduce the use of some highly toxic pesticides and pesticide residues in food and feed, and promote the development of green food and biopesticides in my country.

[0003] In the field of biological control, trichogrammatids are the world's most widely used natural enemies of lepidopteran pests, targeting crops such as rice, corn, sugarcane, and cotton, as well as pests related to pine trees. Using trichogrammatids for farmland pest control actually involves releasing parasitized host eggs into the field. Shortly after the pupal eggs of trichogrammatids are released into the field, the newly emerged trichogrammatids will actively seek out and lay eggs within the host eggs. The pupae then kill the host eggs and absorb their nutrients to complete their own development. Once they emerge, they begin a new round of parasitism. This continuous cycle of reproduction effectively reduces the pest population, thereby achieving the goal of pest control.

[0004] The traditional method of releasing Trichogrammatids in the field involves placing cards containing Trichogrammatid eggs and various spherical release devices into the field. The cards are then manually attached to the plants on the ground. This method of release is labor-intensive, inefficient, and time-consuming. If the eggs are released too long, the effectiveness of pest control can be compromised. The use of drones for large-scale release of Trichogrammatids and other natural enemy insects for pest control has emerged in recent years. Using drones to release Trichogrammatids can be performed by a small number of professionals, ensuring uniform, timely, and effective release of natural enemy insects into the field. This approach replaces the traditional manual release method of Trichogrammatids, saving manpower and resources while improving efficiency and effectiveness.

[0005] At present, we have found drone delivery structures for trichogrammatid balls, glue sticks, and cylindrical biological agent containers. For example, the related patents for drone delivery structures for trichogrammatid balls are: CN201510598566.3, a biological control ball delivery device for aircraft, CN201910955514.5, a field trichogrammatid delivery drone, CN201911021751.0, a biomass ball delivery system and delivery method for drones, CN201921163256.9, a trichogrammatid delivery device, and CN202211010722.6, a trichogrammatid delivery drone. Device and drone, CN202322916528.0 is a drone delivery component for trichogrammatid pupae; patents related to the drone delivery structure of glue sticks include: CN202010841298.4 is a drone delivery device, CN202010841400.0 is a drone delivery device with a buffering function; patents related to the drone delivery structure of cylindrical biological agent containers include: CN202310904920.5 is a drone delivery device and delivery method for natural enemy insects, CN202321857761.X is a trichogrammatid delivery drone.

[0006] Since the trichogrammatid bee ball is easily eaten by other organisms, cannot be affected by weather and has unstable movement trajectory, the glue stick and cylindrical biological agent container have a fast falling speed, which easily causes damage to the delivery components. Therefore, CN202320842035.4 proposes a dart bee release device (such as Figure 13 As shown), it comprises: a dart box for holding bee cards, wherein the lower part of the dart box is provided with an insect outlet; a dart tail wing, wherein the dart tail wing comprises a plurality of blades that are combined to form a spiral structure, and the blades are arranged at the upper part of the dart box; a dart rod, wherein the dart rod is arranged at the lower part of the dart box, and the lower end of the dart rod is set as a dart tip. The utility model utilizes the effect of the air flow on the dart structure during the falling process, so that the dart tail wing composed of two blades drives the entire dart bee releaser to rotate, and realizes the smooth fall of the bee releaser without the need to design a blade rotating shaft. Although CN202010841400.0 proposes a drone delivery device with a buffering function, which mentions the delivery of glue sticks with blades, the delivery structure requires the blades to be retracted and fixed, and cannot match the tail wing of the dart bee releaser made of the above-mentioned hard material. At the same time, the number of glue sticks that can be loaded into the delivery structure at one time is very low, and the darts cannot be effectively loaded, resulting in low delivery efficiency.

[0026] 1. The utility model can effectively load the dart bee releaser.

[0027] The present invention studies the structure of the dart-loading bee releaser of CN202320842035.4 and designs a dart loading chamber with radial and vertical openings. The radial opening allows the tail wing and dart box of the dart-loading bee releaser to extend from the dart loading chamber, exposing the dart loading chamber, and the dart tip to extend into the annular hollow area of ​​the dart loading chamber, while the dart shaft is confined within the dart loading chamber, and the dart loading chamber matches the shape of the dart loading chamber.

At the same time, the radial length of the dart entry is greater than the length of the dart releaser, and the radial length of the second dart exit is less than the length of the dart releaser. Thus, when the dart releaser drops horizontally from the first dart exit, the dart tip of the dart releaser is guaranteed to face downward through the limiting guidance of the inclined panel. Combined with the guidance of the dart receiving guide funnel and the release guide tube, as well as the functions of the inlet acceleration fan and the outlet balancing fan, the dart can be effectively accelerated to rotate and fall smoothly, reducing the interference of wind changes in the natural environment and the wind force of the drone rotor on the dart's falling state, and improving the success rate of the dart tip inserting into the field ground. The dart landing posture accuracy rate is over 95%, and the bee release rate is as high as over 85%, thereby ensuring the control effect of the Trichogramma application.

[0032] 4. The utility model has a simple structure and is easy to promote and apply.

[0033] The utility model has a simple structure and can be conveniently used in combination with existing commercially available agricultural drones. The delivery guide tube can be folded up by an electric push rod during takeoff and landing; during flight, the delivery guide tube is placed vertically by the electric push rod to avoid the impact of the delivery guide tube on the drone, and is easy to promote and apply.

[0059] The present invention will be described in further detail below with reference to the examples, but the implementation of the present invention is not limited to the scope of the examples.

[0060] Example 1:

[0061] like Figure 1 As shown, a dart bee release device includes:

[0062] The dart chamber 1 is used to regularly place a large number of darts that need to be put in the beeper 11; Figure 2-Figure 4As shown, the dart loading chamber 1 is an annular three-dimensional structure, and 10 dart loading chambers 101 are evenly and vertically opened along the annular surface of the dart loading chamber 1, and the upper and lower ends of each dart loading chamber 101 respectively pass through the top and bottom of the dart loading chamber 1, thereby forming openings at the top and bottom of the dart loading chamber 1 for the horizontal radial passage of the dart releasing device 11, and the dart releasing device 11 enters from the top opening and is stacked up and down in the dart loading chamber 101; the radial inner and outer ends of each dart loading chamber 101 respectively pass through the inner wall and outer wall of the side of the dart loading chamber 1, and the head and tail ends of the loaded dart releasing device 11 extend from the inner wall opening and the outer wall opening respectively, and the dart tip 1104 extends into the annular hollow area of ​​the dart loading chamber 1, and the dart rod 1103 is limited in the dart loading chamber 101, and the dart loading chamber 101 matches the shape of the dart loading chamber 1; adjacent dart loading chambers 101 are separated by partition bars 103. Furthermore, a limiting strip 105 can be provided on the inner wall of each dart loading chamber 101, so as to more accurately position the dart releaser 11; a first connecting piece fixedly connected to the upper part of 10 dividing strips 103 is provided at the top center of the dart loading chamber, thereby stabilizing the structure of the dart loading chamber 101; the first connecting piece 102 is an annular hollow structure, and 10 fixing plates are evenly distributed on the circumference of the annular structure.

[0063] like Figure 13 As shown, the dart wasp releaser 11 of the present invention has the structure disclosed in CN202320842035.4, including: a dart box 1101 for holding bee cards, with an insect outlet provided at the bottom of the dart box 1101; a dart tail 1102, which includes a plurality of blades assembled into a spiral structure and disposed at the top of the dart box 1101; and a dart shaft 1103, which is disposed at the bottom of the dart box 1101 and has a dart tip 1104 at its lower end. Since the dart wasp releaser 11 of CN202320842035.4 is already prior art, the present invention will not provide an excessive description thereof. Where not fully described, the dart wasp releaser 11 of CN202320842035.4 shall be understood in accordance with the dart wasp releaser 11. The dart releasers 11 are inserted horizontally and radially into the dart loading chamber 101 through the top opening of the dart loading chamber 101, with the dart tips 1104 facing inward, and then stacked one on top of the other. The radial length of the lower portion of the dart loading chamber 101 is less than the length of the dart releasers 11, ensuring that the dart tips 1104 of the placed dart releasers 11 extend out of the dart loading chamber 101 and into the annular hollow area of ​​the dart loading chamber 1, and that the tail wing and dart box 1101 are exposed outside the dart loading chamber 101. The dart loading chamber 101 of the present invention has a height of 420 mm and can accommodate 46 dart releasers 11 with a thickness of 9 mm. Consequently, the dart loading chamber 1 can accommodate 460 dart releasers 11 at a time, achieving efficient loading.

[0064] like Figure 5As shown, the transmission shaft 2 is located at the axis of the dart loading chamber 1. Two sets of vertically distributed stabilizing components 8 are provided on the transmission shaft 2. Each set of stabilizing components 8 includes a connecting sleeve 801 and ten connecting blocks 802. The connecting sleeve 801 is located on the outer circumference of the transmission shaft 2 and does not rotate with the transmission shaft 2. The ten connecting blocks 802 are evenly distributed on the outer surface of the connecting sleeve 801 and are fixedly connected to corresponding dividing bars 103. The first connecting member 102 is connected to the connecting blocks 802 of the upper stabilizing component 8 via a fixing plate, thereby achieving a fixed connection with the upper portions of the ten dividing bars. The driving member 3 is provided on the annular structure of the first connecting member 102. Its power output end is connected to the upper end of the transmission shaft 2 through the hollow position of the first connecting member 102, driving the transmission shaft 2 to rotate. The driving member 3 of the present utility model is a drive motor.

[0065] like Figure 6 As shown, the dart-dividing clamp 4 is arranged in the annular hollow area of ​​the dart-loading chamber 1, and includes an upper clamping piece 401, a lower clamping piece 402 and a first shaft sleeve 403. The first shaft sleeve 403 is located below the lower stabilizing component 8. The first shaft sleeve 403 is connected to the transmission shaft 2, and is then driven by the transmission shaft 2 to rotate around the axis of the dart-loading chamber 1; the size of the first shaft sleeve 403 is based on not affecting the horizontal falling trajectory of the dart releaser 11 in the dart-loading chamber 101. The upper clamping piece 401 and the lower clamping piece 402 are parallel to each other, and one end thereof is fixedly connected to the first shaft sleeve 403, thereby forming a clamping opening for clamping the dart releaser 11; when the clamping opening of the dart splitting clamp 4 is aligned with the dart loading chamber 101, the upper clamping piece 401 is horizontally inserted between the second and third lowest dart releasers 11 in the annular hollow area, and the lower clamping piece 402 is horizontally inserted between the first and second lowest dart releasers 11 in the annular hollow area, thereby achieving limited clamping of the second lowest dart releaser 11. When it is necessary to load darts, the clamping opening of the dart splitting clamp 4 is rotated to a position opposite to the dividing bar 103, thereby preventing the upper clamping piece 401 and the lower clamping piece 402 from affecting the dart loading chamber 101.

[0066] like Figure 5 and Figure 6As shown, the dart tray 5 is supported on the bottom of the dart loading chamber 1, and the center of the dart tray 5 is fixedly connected to the first shaft sleeve 403, and then rotates synchronously with the transmission shaft 2; a first dart outlet 501 is provided on the dart tray 5, and the first dart outlet 501 is opened along the radial direction of the dart tray 5. The length of the first dart outlet 501 is from the outer side of the first shaft sleeve 403 connected to the dart tray 5 to the edge of the dart tray 5, and the width of the first dart outlet 501 matches the width of the horizontal falling trajectory of the dart releaser 11, so that the dart releaser 11 can fall in the horizontal state of the original dart bin 101; the size of the first dart outlet 501 is only matched with a single horizontally placed dart releaser 11 loaded in the dart bin 101, and cannot be expanded indefinitely to the bottom openings of the remaining dart bins 101, so as to ensure that only one dart releaser 11 loaded in the dart bin 101 falls at a time. The first dart outlet 501 is located just below the clamping opening of the dart dividing clamp 4. When the first low-position dart releaser 11 falls, the dart dividing clamp 4 can limit and clamp the second low-position dart releaser 11 to prevent it from falling. This ensures that each time the first dart outlet 501 passes through a dart loading chamber 101, only one first low-position dart releaser 11 can be taken out for delivery. By rotating the dart tray 5, the first dart outlet 501 is aligned with the dart loading chamber 101 in sequence, so that the first low-position dart releaser 11 of each dart loading chamber 101 can be delivered. In this embodiment, 10 darts can be taken out and delivered at a uniform speed every time the dart tray 5 rotates one circle. The diameter of the dart tray 5 is larger than the bottom diameter of the dart loading chamber 1, so as to ensure that the dart tray 5 can support the dart releaser 11 in the dart loading chamber 1. The outer edge of the upper surface of the dart tray 5 is provided with a plurality of dart loosening blocks 502. As the tray 5 rotates, the top edge of the dart loosening block 502 contacts the portion of the first low-position dart releaser 11 extending outward from the dart loading chamber 101. Because in actual operation, when the dart tray 5 rotates, the lowest dart in the dart loading chamber 101 will be subjected to friction, and occasionally displaced and stuck at the bottom exit of the dart loading chamber 101, affecting the normal dart discharge under the action of gravity. The dart loosening block 502 is a small protrusion set on the upper surface of the dart tray 5. Its function is that when the dart tray 5 rotates and the dart loosening block 502 passes under the first low-position dart releaser 11 of the dart loading chamber 101, the slight contact will cause the first low-position dart releaser 11 above it to continuously vibrate slightly, so that the first low-position dart releaser 11 that occasionally gets stuck will return to a loose state, ensuring that it can fall smoothly under the action of the gravity of the dart releaser 11 itself when passing through the first dart outlet 501.

[0067] like Figure 6As shown, the tag-dropping guide groove 6 is arranged below the dart tray 5. The tag-dropping guide groove 6 includes two right-angled trapezoidal baffles 601, an inclined panel 602, and a second sleeve 603 connected to the transmission shaft 2. The second sleeve 603 is the same size as the first sleeve 403 to ensure that the horizontal falling trajectory of the dart releaser 11 is not affected. The synchronous rotation of the tag-dropping guide groove 6 and the transmission shaft 2 is achieved through the connection between the second sleeve 603 and the transmission shaft 2; the two right-angled trapezoidal baffles 601 and the inclined panel 602 form a structure with upper and lower openings. The two baffles 601 are of the same shape and size, with their right-angled sides fixedly connected to the second sleeve 603 and their inclined sides connected to the inclined panel 602. The upper opening is the dart entry 604. In any state, the dart entry 604 is opposite to the first dart exit 501, and the lower opening is The second dart outlet 605 and the dart inlet 604 are parallel to the second dart outlet 605 . The radial length of the dart inlet 604 is greater than the length of the dart releaser 11 , ensuring that the dart releaser 11 remains horizontal upon its initial fall. The length of the dart releaser 11 is greater than the radial length of the second dart outlet 605 . Thus, when the dart releaser 11 enters the dart inlet 604 , the dart tip 1104 of the dart releaser 11 is guided downward by the limiting mechanism of the inclined panel 602 . Other limitations not described in detail may be reasonably adjusted by persons skilled in the art to achieve the desired effect.

[0068] like Figure 7As shown, a delivery guide 7 is further provided below the dart-dropping guide groove 6, and the delivery guide 7 is mounted on the guide mounting bracket 10. The delivery guide 7 includes a dart-receiving guide funnel 701 and a delivery guide tube 702 arranged upper and lower. The dart-receiving guide funnel 701 is arranged just below the lower end opening of the dart-dropping guide groove 6, and is used to guide the dart releaser 11 with the dart tip 1104 facing downward into the delivery guide tube 702. The delivery guide tube 702 is vertically arranged, and the upper end pipe mouth is connected to the outlet of the dart-receiving guide funnel 701, and the dart releaser falls from the lower end pipe mouth, thereby realizing the delivery direction setting of the dart releaser 11. The upper portion of the delivery guide tube 702 is connected to a downwardly sloping lower oblique tube 703. This lower oblique tube 703 houses an inlet acceleration fan 704, which tilts the air outlet downward. The lower end of the delivery guide tube 702 is connected to an upwardly sloping upper oblique tube 705. This upper oblique tube 705 houses an outlet balancing fan 706, which tilts the air outlet upward. During dart delivery, the dart launcher 11 passes through the dart receiving guide funnel 701 and the delivery guide tube 702 before being released into a field. The inlet acceleration fan 704 provides wind to accelerate the rotation of the dart launcher 11, which has tail blades, and mitigate the effects of wind fluctuations in the natural environment and wind from the drone's rotor blades on the launcher's descent. The outlet balancing fan 706 enhances the stability of the dart launcher 11 at the outlet of the delivery guide tube 702. The comparison of actual release effects shows that under different natural wind environments, the addition of the inlet acceleration fan 704 and the outlet balancing fan 706 can increase the success rate of the dart tip 1104 of the dart release device 11 into the field ground by more than 95%, so that the dart box 1101 is kept away from the ground, effectively increasing the bee emergence rate of Trichogramma eggs and ensuring the prevention and control effect.

[0069] The working principle of this embodiment is as follows: the dart loading chamber 1 and the guide mounting bracket 10 are installed on the drone at a defined position. When not being released, the first dart outlet 501 of the dart tray 5 is placed under the partition bar 103 for shielding, and the clamping opening of the dart clip 4 is also aligned with the partition bar 103. At this time, the dart releaser 11 is horizontally placed in each dart loading chamber 101 in sequence. When the release operation is carried out, the driving motor drives the transmission shaft 2 to rotate, and the dart tray 5 rotates with the transmission shaft 2 to the bottom of the dart loading chamber 101. The dart releaser 11 at the first lower position is placed horizontally in each dart loading chamber 101. The dart releaser 11 passes through the bottom opening of the dart storage bin 101 and falls horizontally from the first dart outlet 501 to the dart drop guide groove 6. The second, lower dart releaser 11 is clamped by the upper and lower clamps 401 and 402 of the dart splitter 4 to prevent it from falling. The dart releaser 11 in the dart drop guide groove 6 is guided by the inclined panel 602 and adjusted to a downward-facing position with the dart tip 1104. Then, as it enters the dart receiving guide funnel 701 and the delivery guide tube 702, the dart releaser 11 falls vertically with the dart tip 1104 facing downward. Combined with the inlet acceleration fan 704 and the outlet balancing fan 706, the dart can be effectively accelerated to rotate and fall steadily, reducing the interference of wind changes in the natural environment and the wind force of the drone rotor on the dart's falling state, and improving the success rate of the dart tip 1104 of the delivered dart into the field ground. When the transmission shaft 2 drives the first dart outlet 501 to rotate to the next dart loading chamber 101, the dart splitter 4 simultaneously shifts, and the dart releaser 11 in the second lowest position in the previous dart loading chamber 101 is released from its restraint and falls to the first lowest position by gravity. It is then supported by the dart tray 5 in the dart loading chamber 101 and awaits the next passage of the first dart outlet 501. By driving the dart tray 5 to rotate at a constant speed for one full revolution, the transmission shaft 2 can achieve uniform delivery of ten dart releasers 11. The present invention can be used for crops such as rice, corn, sugarcane, cotton, and pine trees. Of course, other scenarios where dart releasers 11 can be used are also suitable for the present invention.

The drone body 9 involved in this utility model is prior art, and any commercially available drone with a corresponding cargo platform 901 and landing and take-off tripod 902 can be used in this utility model. The dart-dispensing bee releaser device of Example 1 is mounted on the cargo platform 901 and the landing and take-off tripod 902. The loading chamber 1 is arranged at the center of the through hole 903 and is fixedly connected to the cargo platform 901 through the second connecting member 104; the second connecting member 104 is annularly arranged on the outer periphery of the loading chamber 1, and an extension strip is arranged in the annular structure to be connected to the outer wall of the partition strip 103 between the loading chamber 101; the guide mounting bracket 10 is arranged below the through hole 903 and is fixedly clamped between the two landing legs 902 by a bracket fixing clamp 1012.

[0072] like Figure 10 As shown, the guide mounting bracket 10 includes a horizontal bracket 1001, a funnel port clamp 1002 is fixedly connected to the middle of the horizontal bracket 1001, which can clamp the dart receiving guide funnel 701, and a movable delivery guide tube clamp 1003 is provided below the funnel port clamp 1002. The delivery guide tube clamp 1003 is a U-shaped structure consisting of an arc piece 1006 and four hinged rods. One end of the arc piece 1006 is fixedly connected to two hinged rods, and the other end is also fixedly connected to two hinged rods. The two hinged rods at the same end are parallel to each other, and in this embodiment are referred to as the upper hinged rod 1006. 7 and the lower hinged rod 1008, the guide tube clamp clamps the upper part of the delivery guide tube 702 through a U-shaped structure, and a push rod bracket 1004 is provided on the horizontal bracket 1001 near the U-shaped opening end, and the push rod bracket 1004 is hinged to the base of the electric push rod 1005 through the base pin 1009; the end of the upper hinged rod 1007 near the U-shaped opening end is hinged to the funnel port clamp 1002 through the bracket pin 1010, and the end of the lower hinged rod 1008 near the U-shaped opening end is hinged to the screw of the electric push rod 1005 through the screw pin 1011.

[0073] like Figure 10 、 Figure 11 and Figure 12 As shown, the screw rod of the electric push rod 1005 extends downward, pushing the delivery guide tube 702 downward through the screw rod pin 1011 and the guide tube clamp, and the delivery guide tube 702 is rotated to be directly below the dart receiving guide funnel 701. The screw rod of the electric push rod 1005 retracts upward, and the screw rod pin 1011 and the guide tube clamp drive the delivery guide tube 702 to swing upward to a horizontal state, thereby preventing the delivery guide tube 702 from being affected during drone takeoff and landing.
