Description

Technical Field

[0001] The invention belongs to the field of biological control, and in particular relates to a dart bee release device and a drone. Background Art

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

[0003] In the field of biological control, trichogrammatids are the most widely used natural enemies of lepidopteran pests in the world. They control crops such as rice, corn, sugarcane, cotton, and related pests of pine trees. When using trichogrammatids for farmland pest control, the host eggs parasitized by trichogrammatids are actually released into the field. Soon after the host eggs of trichogrammatids in the pupal stage are released in the field, the trichogrammatids will actively look for host eggs and lay eggs in the host eggs after they emerge. The trichogrammatid pupae will kill the host eggs and absorb their nutrients to complete their own development. After they emerge, they will start a new round of parasitism. This continuous cycle of reproduction can effectively reduce the base number of pests, thereby achieving the purpose of controlling pests.

[0004] The traditional method of releasing trichogrammatids in the field is to place bee cards containing trichogrammatid eggs and various spherical releasers into the field, and manually stick the trichogrammatid cards on the plants one by one on the ground for release. This release method will waste a lot of labor, and has low work efficiency and a long release time. If the release time of trichogrammatid eggs is too long, it will also affect the effect of pest control. Using drones to release trichogrammatids and other natural enemy insects on a large scale to control pests is a new method that has emerged in recent years. The use of drones to release trichogrammatids can be completed by a small number of professionals, so that natural enemy insects can be released evenly, timely and effectively into the field, thus changing the previous method of manually releasing trichogrammatids, saving manpower and material resources, and improving work efficiency and control effects.

[0005] At present, we have found drone delivery structures for trichogrammatid balls, glue sticks, and cylindrical biological agent containers. For example, the relevant patents for drone delivery structures for trichogrammatid balls include: 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 device. Device and drone, CN202322916528.0 is a drone component for releasing trichogrammatid pupae; related patents for drone release structures such as glue sticks include: CN202010841298.4 is a drone release device, CN202010841400.0 is a drone release device with buffering function; related patents for drone release structures such as cylindrical biological agent containers include: CN202310904920.5 is a drone release device and release method for natural enemy insects, CN202321857761.X is a trichogrammatid release drone.

[0006] Since the trichogrammatid bee ball is easily eaten by other organisms, cannot be affected by weather and cannot molt, and has unstable movement trajectory, the glue stick and cylindrical biological agent container have a fast falling speed, which is easy to cause damage to the delivery components. Therefore, CN202320842035.4 proposes a dart bee release device (such as Fig.13 As shown), comprising: a dart box for accommodating bee cards, wherein a worm outlet is provided at the lower part of the dart box; a dart tail wing, wherein the dart tail wing comprises a plurality of blades which are combined to form a spiral structure, and wherein the blades are arranged at the upper part of the dart box; and 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 arranged as a dart tip. The utility model utilizes the effect of 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 the bee releaser can be smoothly dropped 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 delivery structure can only load a very low number of glue sticks at a time, and the darts cannot be effectively loaded, resulting in low delivery efficiency.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with examples, but the implementation mode of the present invention is not limited to the scope represented by the examples.

[0030] Embodiment 1: like Figure 1 As shown, a dart bee release device comprises: The dart loading room 1 is used to regularly place a large number of darts that need to be released. Figure 2-Figure 4 As 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 penetrate the top and bottom of the dart loading chamber 1, so as to form 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 penetrate the inner wall and the 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 out 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 its loading; 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, so as to stabilize 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 annular structure in a circumferential manner.

[0031] like Fig.13 As shown, the dart bee releaser 11 loaded in the present invention is the structure disclosed in the dart bee releaser 11 of CN202320842035.4, including: a dart box 1101 for holding bee cards, the lower part of the dart box 1101 is provided with an insect outlet; a dart tail 1102, the dart tail 1102 includes a plurality of blades in a spiral structure after being combined, and the blades are arranged at the upper part of the dart box 1101; a dart rod 1103, the dart rod 1103 is arranged at the lower part of the dart box 1101, and the lower end of the dart rod 1103 is set as a dart tip 1104. Since the dart bee releaser 11 of CN202320842035.4 is already a prior art, the present invention does not explain it too much, and the parts not explained in detail shall be understood according to the dart bee releaser 11 of CN202320842035.4. The dart washer 11 is horizontally and radially loaded into the dart loading bin 101 from the top opening of the dart loading bin 101, with the dart tip 1104 facing inward, and then stacked up and down one by one. The radial length of the lower part of the dart loading bin 101 is smaller than the length of the dart washer 11, so as to ensure that the dart tip 1104 of the placed dart washer 11 extends out of the dart loading bin 101 and enters the annular hollow area of ​​the dart loading chamber 1, and the tail wing and the dart box 1101 are exposed outside the dart loading bin 101. The height of the dart loading bin 101 of the present invention is 420mm, which can be loaded with 46 dart washer 11 with a thickness of 9mm, and then the dart loading chamber 1 can be loaded with 460 dart washer 11 at a time, so as to achieve effective loading.

[0032] like Figure 5As shown, the transmission shaft 2 is arranged at the axis of the dart chamber 1, and two groups of upper and lower distributed stabilizing components 8 are arranged on the transmission shaft 2, each group of stabilizing components 8 includes a connecting sleeve 801 and 10 connecting blocks 802, the connecting sleeve 801 is arranged on the outer circumference of the transmission shaft 2, and does not rotate with the transmission shaft 2; the 10 connecting blocks 802 are evenly distributed on the outer surface of the connecting sleeve 801, and are fixedly connected with the corresponding dividing strips 103; the first connecting member 102 is connected to the connecting blocks 802 of the upper stabilizing component 8 one by one through the fixing plate, so as to realize the fixed connection with the upper part of the 10 dividing strips. The driving member 3 is arranged on the annular structure of the first connecting member 102, and its power output end is connected to the upper end of the transmission shaft 2 from the hollow position of the first connecting member 102, driving the transmission shaft 2 to rotate. The driving member 3 of the present invention is a driving motor.

[0033] 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 clamp 401, a lower clamp 402 and a first sleeve 403. The first sleeve 403 is located below the lower stabilizing component 8. The first sleeve 403 is connected to the transmission shaft 2, and then driven by the transmission shaft 2 to rotate around the axis of the dart-loading chamber 1; the size of the first 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 realizing the limited clamping of the second lowest dart releaser 11. When it is necessary to load darts, when the clamping opening of the dart splitting clamp 4 is turned to a position opposite to the partition bar 103, the influence of the upper clamping piece 401 and the lower clamping piece 402 on the dart loading chamber 101 is avoided.

[0034] like Figure 5 and Figure 6As shown, the dart tray 5 is supported at the bottom of the dart loading chamber 1, 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 opened from the outer side of the first shaft sleeve 403 connected to the dart tray 5 to the edge of the dart tray 5, the width of the first dart outlet 501 matches the width of the horizontal falling trajectory of the dart washer 11, so that the dart washer 11 can keep the original dart bin 101 in the horizontal state when falling; the size of the first dart outlet 501 is only matched with the horizontally placed dart washer 11 of a single dart bin 101, and cannot be infinitely expanded to the bottom openings of the remaining dart bins 101, so as to ensure that only one dart washer 11 of the dart bin 101 falls at a time. The first dart outlet 501 is located just below the clamping opening of the dart splitting clamp 4. When the first low-position dart releaser 11 falls, the dart splitting 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; through the rotation of 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 is delivered. In this embodiment, 10 darts can be taken out and delivered at a uniform speed for each rotation of the dart tray 5. 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; a plurality of dart loosening blocks 502 are provided on the outer edge of the upper surface of the dart tray 5, through which the darts are delivered. 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 out of the dart chamber 101. In actual operation, when the dart tray 5 rotates, the lowest dart in the dart chamber 101 will be subjected to friction, and occasionally will be displaced and stuck at the bottom exit of the dart chamber 101, affecting the normal dart discharge under the action of gravity. The dart loosening block 502 is a small protrusion arranged 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 in the dart chamber 101, 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 resume 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.

[0035] 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, and their right-angled sides are fixedly connected to the second sleeve 603, and their inclined sides are connected to the inclined panel 602. The upper opening is the dart entrance 604. In any state, the dart entrance 604 is opposite to the first dart exit 501 in the upper and lower directions, 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 washer 11, so that the dart washer 11 falls and maintains the initial horizontal state; the length of the dart washer 11 is greater than the radial length of the second dart outlet 605. In this way, when the dart washer 11 enters from the dart inlet 604, the dart tip 1104 of the dart washer 11 can be guaranteed to face downward through the limit guidance of the inclined panel 602. Other limitations not described in detail can be reasonably adjusted by ordinary technicians in this field according to the effects that can be achieved.

[0036] like Figure 7As shown, a delivery guide 7 is also provided below the tag-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 which are arranged upper and lower. The dart receiving guide funnel 701 is arranged just below the lower end opening of the tag-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. One side of the upper tube body of the delivery guide tube 702 is connected to a downwardly inclined lower oblique tube 703, and an inlet acceleration fan 704 is arranged in the lower oblique tube 703, so that the air outlet of the inlet acceleration fan 704 can be tilted downward to blow out; one side of the lower end tube mouth of the delivery guide tube 702 is connected to an upwardly inclined upper oblique tube 705, and an outlet balancing fan 706 is arranged in the upper oblique tube 705, so that the air outlet of the outlet balancing fan 706 can be tilted upward to blow out. When performing the dart delivery operation, the dart bee releaser 11 passes through the dart receiving guide funnel 701 and the delivery guide tube 702 and is delivered to the field. The function of the inlet acceleration fan 704 is to provide wind force to appropriately accelerate the rotation and fall of the dart bee releaser 11 with tail blades, and reduce the interference of the wind force changes in the natural environment and the wind force of the drone rotor on the falling state of the dart bee releaser 11. The function of the outlet balancing fan 706 is to improve the stability of the dart bee releaser 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 an inlet acceleration fan 704 and an outlet balancing fan 706 can increase the success rate of the dart tip 1104 of the dart release device 11 being inserted into the field ground by more than 95%, thereby keeping the dart box 1101 away from the ground, effectively increasing the emergence rate of Trichogramma eggs, and ensuring the control effect.

[0037] 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 performed, the driving motor drives the transmission shaft 2 to rotate, and the dart tray 5 rotates with the transmission shaft 2 to the right below the dart loading chamber 101. The dart releaser 11 at the first low position is placed horizontally in each dart loading chamber 101. The beeper 11 falls horizontally from the first dart outlet 501 to the target drop guide groove 6 through the bottom opening of the dart storage bin 101, and the second lowest dart beeper 11 is clamped by the upper clamp 401 and the lower clamp 402 of the dart clip 4 to prevent it from falling; the dart beeper 11 in the target drop guide groove 6 is guided by the inclined panel 602 and adjusted to the state where the dart tip 1104 is facing downward, and then as it enters the dart receiving guide funnel 701 and the delivery guide tube 702, the dart beeper 11 forms a vertical falling state 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, reduce the interference of the wind force changes in the natural environment and the wind force of the drone rotor on the dart falling state, and improve the success rate of the dart tip 1104 of the dart being inserted into the field ground. When the transmission shaft 2 drives the first dart outlet 501 to rotate to the next dart loading bin 101, the dart splitter 4 is transferred at the same time, and the dart releaser 11 at the second lowest position in the previous dart loading bin 101 is released from the restriction, falls to the first lowest position by gravity, and is supported by the dart tray 5 in the dart loading bin 101, waiting for the next first dart outlet 501 to pass. The transmission shaft 2 drives the dart tray 5 to rotate at a uniform speed for one circle, so that 10 dart releasers 11 can be evenly released. The device of the present invention can be used for crops such as rice, corn, sugarcane, cotton, and pine trees, etc. Of course, other scenes where the dart releaser 11 can be used are also suitable for the device of the present invention.
