Description

Technical Field

[0001] The invention belongs to the technical field of pest control, and in particular relates to a natural enemy insect releasing device for forest pest control. Background Art

[0002] In the cultivation of large-diameter timber, healthy tree growth is crucial for ensuring timber quality and yield. However, outbreaks of forestry pests such as the pine wood nematode, the longhorn beetle, and the red bark borer often lead to widespread tree mortality, causing significant economic and ecological losses. In recent years, my country has gradually adopted a drone biological control system, combining drones with delivery equipment. This system has achieved certain results and has been widely adopted in pest control efforts nationwide, effectively reducing pollution caused by chemical pest control, minimizing pest losses, and increasing crop yields and vegetation coverage.

[0003] Chinese invention CN 112874790 B discloses a drone-mounted natural enemy insect releaser, comprising a release base body with a release mechanism and a hopper body located above the release base body. Key technical features include: a flat hopper body with a thickness matching the length of the feeding tube; a fixed side panel, a surrounding panel, and a movable side panel; multiple magnetic structures disposed between the edges of the movable side panel and the surrounding panel; a release base body comprising left and right side panels, front and rear baffles, which form a release bin; and a release mechanism comprising a release roller supported within the release bin, with multiple accommodating grooves uniformly disposed on the outer circumference of the release roller, each accommodating the natural enemy insect feeding tube. This invention addresses the mismatch between the hopper and release mechanism of existing releasers and the natural enemy insect feeding tubes, ensuring that the feeding tubes fill the hopper in an orderly manner and are released smoothly. It also enables rapid assembly and disassembly of the hopper and release base, improving release efficiency. However, the feeding tubes of this natural enemy insect releaser are placed on the ground, preventing the insects from quickly reaching the target trees and preventing pests and diseases on them. Therefore, we propose a natural enemy insect releasing device for preventing and controlling forest diseases and insect pests to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the current natural enemy insect releaser has a feeding tube placed on the ground, which causes the insects to be unable to quickly reach the target trees and prevent and control the diseases and insect pests of the target trees.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] A natural enemy insect release device for forest pest control includes an unmanned aerial vehicle (UAV) body capable of identifying and detecting the status of trees, a delivery mechanism arranged below the UAV body, and a feeding tube arranged within the delivery mechanism. A pull rope is provided at the upper end of the feeding tube, a fixed shaft is fixedly mounted on the upper end of the pull rope, a plurality of guide vanes are fixedly mounted on the outside of the fixed shaft, a fixed cylinder with an opening at one end is fixedly mounted on the plurality of guide vanes, the opening is located at the end of the fixed cylinder away from the fixed shaft, a counterweight bead is movably mounted in the fixed cylinder, a winding line is connected between the counterweight bead and the wall of the fixed cylinder, and a blocking piece is provided at the lower end of the feeding tube for connecting the inside and outside of the feeding tube when the feeding tube is delivered.

[0007] The invention further defines that the feeding mechanism includes a fixed plate, a plurality of placement tubes fixedly mounted at the lower end of the fixed plate for storing feeding tubes, and a rotating cover rotatably mounted at the lower end of the placement tubes. The rotating cover is fixedly mounted with fixed magnetic blocks, and the placement tubes are fixedly mounted with electromagnets that match the fixed magnetic blocks. With this structural design, when the electromagnets are energized, they generate a magnetic attraction force on the fixed magnetic blocks, thereby locking the rotating cover.

[0008] The invention further defines a T-shaped block fixedly mounted on the upper end of the fixing plate, a mounting base compatible with the T-shaped block fixedly mounted on the lower end of the drone body, and a locking member provided on the mounting base for locking the T-shaped block. This structural design allows the T-shaped block to be locked to the lower end of the mounting base via the locking member, facilitating assembly of the fixing plate and the placement tube.

[0009] It is further defined that the locking member includes a movable clamping column, a compression spring, and a pull rod, the mounting base is provided with a slot, the movable clamping column is movably mounted in the slot, the T-shaped clamping block is provided with a groove adapted to fit the movable clamping column, the compression spring is fixedly mounted between the movable clamping column and the slot wall, and the pull rod passes through the side of the mounting base and is fixedly connected to the movable clamping column. This structural design is simple and easy to use.

[0010] The invention further defines that the blocking member includes a conical counterweight, a fixed post fixedly mounted on the conical counterweight, two limiting rods fixedly mounted on the upper ends of the fixing posts, and a through-slot defined in the fixing posts. The lower end of the feeding tube defines a mounting slot, the fixing posts are movably inserted into the mounting slot, the mounting slot walls are defined with multiple latching slots, and the fixing posts are provided with multiple movable latches that fit within the latching slots. With this structural design, when the conical counterweight and the feeding tube move relative to each other under inertia, the limiting rods contact the bottom of the inner wall of the feeding tube, opening the through-slots and connecting the inside and outside of the feeding tube, thereby releasing insects from the tube.

[0011] The movable clamp further defines a mounting tube, a movable column with a semicircular end, and a return spring. The fixed column is provided with a plurality of cylindrical grooves, the mounting tube is fixedly mounted within the cylindrical grooves, the movable column is movably mounted within the mounting tube, the inner wall of the mounting groove is provided with a hemispherical groove adapted to fit the end of the movable column, and the return spring is fixedly mounted between the movable column and the wall of the mounting tube. With this structural design, the movable column can be snapped into the hemispherical groove under the elastic force of the return spring, thereby locking the position of the fixed column and the conical counterweight block, thereby sealing the lower end of the feeding tube.

[0012] It is further defined that the pull rope and the guide vane are both made of degradable materials. With such a structural design, after the feeding tube has been put in for a period of time, the pull rope and the guide vane can naturally degrade, allowing the feeding tube to fall down smoothly.

[0013] Furthermore, the lower end of the pull rope is fixedly mounted with a threaded post, and the upper end of the feeding tube is provided with a threaded groove adapted to the threaded post. This structural design facilitates the assembly of the guide vane portion and the feeding tube portion through the threaded post and the threaded groove.

[0014] The invention adopting the above technical solution has the following advantages:

[0015] 1. In the present invention, after the feeding tube is dropped above the target tree by the dropping mechanism, the feeding tube and the guide vane portion fall downward, and the guide vane portion rotates at high speed, which will throw out the counterweight beads in the fixed cylinder, and then bring the winding wire out of the fixed cylinder and keep it in a taut state. When the feeding tube falls on the tree crown, the winding wire will be wrapped around the branch. At this time, the blocking piece connects the inside and outside of the feeding tube, which can release natural enemy insects outward and enable them to reach the target tree more quickly, thereby preventing and controlling forest pests and diseases.

[0016] 2. In the present invention, when the winding line is wrapped around a branch, the feeding tube is subjected to a pulling force, the speed decreases rapidly, and the conical counterweight block drives the fixed column to continue to move downward due to inertia until the limit rod contacts the bottom of the inner wall of the feeding tube. At this time, the through groove connects the inner and outer spaces of the feeding tube, so that the insects inside the feeding tube can be smoothly released outward, which is more convenient to use.

The upper end of the feeding tube 3 is provided with a pull rope 4, and the upper end of the pull rope 4 is fixedly installed with a fixed shaft, and a plurality of guide blades 5 are fixedly installed on the outside of the fixed shaft. A fixed cylinder 51 with an opening at one end is fixedly installed on the plurality of guide blades 5, and the opening is located at the end of the fixed cylinder 51 away from the fixed shaft. A counterweight bead 52 is movably installed in the fixed cylinder 51, and a winding line 53 is connected between the counterweight bead 52 and the cylinder wall of the fixed cylinder 51. The lower end of the feeding tube 3 is provided with a blocking member that can connect the inside and outside of the feeding tube 3 when the feeding tube 3 is delivered.

[0042] The delivery mechanism 2 includes a fixed plate 21, multiple placement tubes 22 fixedly mounted at the lower end of the fixed plate 21 for storing the feeding tubes 3, and a rotating cover 23 rotatably mounted at the lower end of the placement tubes 22. A fixed magnetic block 24 is fixedly mounted on the rotating cover 23, and an electromagnet 25 adapted to the fixed magnetic block 24 is fixedly mounted on the placement tube 22. A battery and a controller electrically connected to the electromagnet 25 are provided on the drone body 1. Different natural enemy insects can be stored in the feeding tubes 3 in the multiple placement tubes 22 to prevent and control different types of diseases and pests.

[0043] A T-shaped block 211 is fixedly installed on the upper end of the fixing plate 21, and a mounting seat 6 adapted to the T-shaped block 211 is fixedly installed on the lower end of the drone body 1. A locking member for locking the T-shaped block 211 is provided on the mounting seat 6. The locking member includes a movable clamping column 61, a compression spring 62 and a pull rod 63. A slot is provided on the mounting seat 6, and the movable clamping column 61 is movably installed in the slot. A groove adapted to the movable clamping column 61 is provided on the T-shaped block 211, and the compression spring 62 is fixedly installed between the movable clamping column 61 and the slot groove wall. The pull rod 63 passes through the side of the mounting seat 6 and is fixedly connected to the movable clamping column 61. The movable clamping column 61 can be pulled by the pull rod 63 to facilitate the release of the clamping effect on the T-shaped block 211.

[0044] The blocking member includes a conical counterweight block 31, a fixing column 32 fixedly mounted on the conical counterweight block 31, two limiting rods 33 fixedly mounted on the upper end of the fixing column 32, and a through slot 34 provided on the fixing column 32. A mounting slot is provided at the lower end of the feeding tube 3, and the fixing column 32 is movably inserted into the mounting slot. A plurality of card slots are provided on the wall of the mounting slot, and a plurality of movable card members adapted to the card slots are provided in the fixing column 32.

[0045] The movable clamp includes a mounting cylinder 321, a movable column 322 with a semicircular end, and a return spring 323. A plurality of cylindrical grooves are provided on the fixed column 32. The mounting cylinder 321 is fixedly mounted in the cylindrical groove. The movable column 322 is movably mounted in the mounting cylinder 321. A hemispherical groove that matches the end of the movable column 322 is provided on the inner wall of the mounting groove. The return spring 323 is fixedly mounted between the movable column 322 and the wall of the mounting cylinder 321. The end of the movable column 322 will extend into the hemispherical groove under the elastic force of the return spring 323, which can generate a force on the fixed column 32 to keep it in a blocked state against the lower end of the feeding tube 3.

[0046] The pull rope 4 and the guide blade 5 are both made of degradable materials. After the natural enemy insects are released and a period of time has passed, the pull rope 4 and the guide blade 5 can be naturally degraded. At this time, the feeding tube 3 can fall freely downward, which is convenient for its recovery. The lower end of the pull rope 4 is fixedly installed with a threaded column 41, and the upper end of the feeding tube 3 is provided with a threaded groove adapted to the threaded column 41, which is convenient for assembling the feeding tube 3 and the guide blade 5.

[0047] The method of use of the present invention is as follows:

[0048] When in use, the drone body 1 flies over the woods to identify and detect trees affected by pests and diseases. After determining the target tree, the drone body 1 flies over the target tree and controls the conduction state of the electromagnet 25 circuit through the controller, so that the electromagnet 25 on one of the placement tubes 22 releases the magnetic attraction effect on the fixed magnetic block 24, and the rotating cover 23 rotates freely, so that the feeding tube 3 inside the placement tube 22 can be released downward;

[0049] The placement tube 22 and the guide vane 5 partially fall downward. During the falling process, the guide vane 5 rotates at high speed, which can throw the weight bead 52 inside the fixed tube 51 outward, thereby bringing the winding line 53 out of the fixed tube 51 and keeping it in a taut state. When the feeding tube 3 falls on the tree crown, the winding line 53 will be entangled on the branches;

[0050] When the winding line 53 is wrapped around the tree branch, the feeding tube 3 is subjected to a pulling force and its speed decreases rapidly. The conical counterweight block 31 is driven by inertia to drive the fixing column 32 to continue to move downward until the limit rod 33 contacts the bottom of the inner wall of the feeding tube 3. At this time, the through groove 34 will connect the inner and outer spaces of the feeding tube 3, so that the insects inside the feeding tube 3 can be released smoothly to the outside, so that they can reach the target tree more quickly and prevent and control forest pests and diseases.

[0051] The above describes in detail the natural enemy insect release device for forest pest control provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will be able to make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the claims.
