Description

Technical Field

[0001] This utility model relates to the field of insect release technology, and in particular to a directional release device for natural enemy insects of the tea oil stem borer. Background Technology

[0002] Camellia oleifera is an important woody oil crop in my country, and its tea oil is highly sought after in the market due to its high quality and rich nutritional value. However, the camellia oleifera industry has long been threatened by various pests and diseases, among which the camellia oleifera stem borer (mainly referring to borer moths such as the camellia leafminer and the tea branch sickle moth) is one of the most serious pests. The larvae of these pests bore into the branches and trunks of the camellia oleifera tree, feeding on the xylem and pith, causing the branches and trunks to wither and growth to be stunted, and in severe cases, leading to the death of the entire tree, posing a huge threat to the sustainable development of the camellia oleifera industry.

[0003] Traditional release methods are mostly manual, point-to-point releases, where workers carry containers containing natural enemies, walk through the forest, and release them one by one. This method is time-consuming and labor-intensive, unable to effectively cover large areas in a short time, resulting in insufficient density of natural enemy populations and difficulty in achieving effective suppression. The occurrence and distribution of tea oleifera stem borers are often uneven, appearing in "patchy" patterns. Traditional large-scale, indiscriminate release methods result in a large number of natural enemies being wasted in areas with low pest density, while severely affected areas do not receive sufficient replenishment of natural enemies, leading to low utilization of control resources. Natural enemy insects inside the containers, especially during transportation and release, are easily squeezed, damaged, or even killed due to excessive density and unsuitable environments (such as high temperature and lack of oxygen). In addition, at the release opening, some insects may hesitate or crowd together and get stuck at the exit, unable to fly out smoothly, and ultimately die, causing unnecessary losses. Currently, there is a lack of automated and intelligent release equipment specifically designed for natural enemies of borer pests on the market. Existing release devices are mostly simple containers with limited functions, unable to achieve targeted, quantitative, and efficient release, which seriously restricts the promotion and application of biological control technology.

[0004] To address the above problems, it is necessary to design a directional release device for the natural enemies of the tea oleifer stem borer, thereby overcoming these issues. Summary of the Invention

[0005] The main objective of this invention is to provide a directional release device for the natural enemy insects of the tea oil stem borer, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A directional release device for natural enemies of the tea oleifera stem borer includes a protective box and a support frame. A sealing box is installed at one end of the top of the protective box, and a sealing ring is connected to the top of the sealing box. A breeding tank is connected to the top of the sealing ring. Multiple release ports are opened on the outer wall of the breeding tank. A protective cylinder is fitted onto one end of the outer wall of the breeding tank. A lower fixing sleeve and an upper fixing sleeve are fixedly installed at both ends of the protective cylinder. A sealing ring is fitted onto the inner surface of the lower fixing sleeve and the upper fixing sleeve. Multiple arc-shaped limiting pads are installed on the inner surface of the sealing rings. Multiple elastic scraping rods are installed on the inner surface of the multiple arc-shaped limiting pads. A reinforcing block is installed at one end of the lower fixing sleeve. A movable panel is installed at the end of the reinforcing block away from the lower fixing sleeve. An upper sealing cylinder is fitted onto the top of the breeding tank.

[0007] As a preferred embodiment of this utility model, a rotating seat is provided on the inner side of the protective box. The output end of the rotating seat is rotatably connected to the bottom of the breeding tank by means of a rotating shaft passing through the top of the sealed box. Telescopic rods are installed at both ends of the top of the movable panel. The end of the movable panel away from the reinforcing block is connected to a lifting screw through a slider.

[0008] As a preferred embodiment of this utility model, the protective sleeve is fitted onto one end of the outer wall of the breeding tank, and the protective sleeve is fixedly connected to the lower fixed sleeve and the upper fixed sleeve.

[0009] In a preferred embodiment of this utility model, both the lower fixing sleeve and the upper fixing sleeve are fixedly connected to the sealing ring, and the sealing ring is fixedly connected to a plurality of the arc-shaped limiting pads.

[0010] As a preferred embodiment of this utility model, the arc-shaped limiting pad is fixedly connected to the plurality of elastic scraping rods, and the inner side of the plurality of elastic scraping rods contacts the outer wall of the breeding tank.

[0011] In a preferred embodiment of this utility model, the lower fixing sleeve is fixedly connected to the reinforcing block via a mounting rod, and the reinforcing block is fixedly connected to the movable panel.

[0012] As a preferred embodiment of this utility model, the telescopic rod is rotatably connected to the top of the movable panel, the movable panel is threadedly fixed to the lifting screw via a slider, and the lifting screw is disposed on the inner side of the support frame.

[0013] Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: This directional release device for the natural enemies of the tea oleifera stem borer uses a rotating base to drive the rearing tank to rotate via a rotating shaft. A lifting screw, driven by a motor, moves a movable panel up and down on one side of the support frame. This, in turn, causes the lower and upper fixed sleeves to rise and fall against the outer wall of the rearing tank, allowing the insects inside to be released from the release port. An upper sealing cylinder provides a sealing and limiting effect on the rearing tank. Sealing rings and arc-shaped limiting pads on the inner sides of the lower and upper fixed sleeves further seal and limit the movement of the rearing tank. Multiple elastic scraping rods on the inner side of the arc-shaped limiting pad scrape away insects stuck in the release port as the rearing tank rotates, causing them to fall back into the rearing tank.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-5As shown, a directional release device for natural enemies of the tea oleifera stem borer includes a protective box 1 and a support frame 2. A sealing box 4 is installed at one end of the top of the protective box 1. A sealing ring 5 is connected to the top of the sealing box 4. A breeding tank 14 is connected to the top of the sealing ring 5. Multiple release ports 15 are opened on the outer wall of the breeding tank 14. A protective cylinder 6 is sleeved on one end of the outer wall of the breeding tank 14. A lower fixing sleeve 7 and an upper fixing sleeve 8 are fixedly installed at both the upper and lower ends of the protective cylinder 6. A sealing ring 16 is sleeved on the inner side of the lower fixing sleeve 7 and the upper fixing sleeve 8. Multiple arc-shaped limiting pads 17 are installed on the inner side of the sealing ring 16. Multiple elastic scraping rods 18 are installed on the inner side of the multiple arc-shaped limiting pads 17. A reinforcing block 9 is installed at one end of the lower fixing sleeve 7. A movable panel 10 is installed at the end of the reinforcing block 9 away from the lower fixing sleeve 7. An upper sealing cylinder 13 is sleeved on the top of the breeding tank 14. The protective sleeve 6 is fitted onto one end of the outer wall of the breeding tank 14. The protective sleeve 6 is fixedly connected to the lower fixing sleeve 7 and the upper fixing sleeve 8. The lower fixing sleeve 7 and the upper fixing sleeve 8 are fixedly connected to the sealing ring 16. The sealing ring 16 is fixedly connected to multiple arc-shaped limiting pads 17. The arc-shaped limiting pads 17 are fixedly connected to multiple elastic scraping rods 18. The inner side of the multiple elastic scraping rods 18 contacts the outer wall of the breeding tank 14. The lower fixing sleeve 7 is fixedly connected to the reinforcing block 9 through the mounting rod. The reinforcing block 9 is fixedly connected to the movable panel 10. The inner side of the protective box 1 is provided with a rotating seat 3. The output end of the rotating seat 3 is rotatably connected to the bottom of the breeding tank 14 through the top of the sealed box 4 via a rotating shaft. Both ends of the top of the movable panel 10 are equipped with telescopic rods 11. The end of the movable panel 10 away from the reinforcing block 9 is connected to a lifting screw 12 via a slider. The telescopic rod 11 is rotatably connected to the top of the movable panel 10. The movable panel 10 is threadedly fixed to the lifting screw 12 via a slider. The lifting screw 12 is located on the inner side of the support frame 2. Specifically, in this embodiment, a rotating base 3 is fixedly installed at the center of the interior of the protective box 1. The rotating base 3 integrates a drive motor and a reducer (not shown in the figure), and its output end is a rotating shaft. A through hole is provided on the top plate of the protective box 1 corresponding to the position of the rotating shaft, and a sealing box 4 is installed thereon. The upper end of the rotating shaft passes through the top of the sealing box 4 and is detachably fixed to the bottom center of the breeding tank 14 via a flange or key connection. The function of the sealing box 4 is to prevent external rainwater and dust from entering the interior of the protective box 1, while also providing a seal and support for the rotating shaft. The breeding tank 14 is a cylindrical or near-cylindrical container made of lightweight and sturdy materials such as engineering plastics or aluminum alloy. Multiple release ports 15 are evenly distributed on its side walls. The size of these release ports 15 is optimized according to the body size of the released predatory insects, ensuring that the insects can pass through smoothly while preventing a large number of them from escaping in the non-released state. An upper sealing cylinder 13 is fitted onto the top opening of the breeding tank 14 to seal the tank after the insects are loaded. Inside the support frame 2, a lifting screw 12 is installed vertically. The bottom end of the lifting screw 12 is connected to the bottom of the protective box 1 or the support frame 2 via a bearing, and its top end is connected to the lifting motor installed on the top of the support frame 2. A slider is threadedly connected to the lifting screw 12, and the slider is fixedly connected to a movable panel 10. To ensure that the movable panel 10 does not twist during lifting, a telescopic rod 11 is connected to each end of its top. The other end of the telescopic rod 11 is fixed to the top crossbeam of the support frame 2, serving as a guide and stabilizer. A reinforcing block 9 is fixedly connected to one side of the movable panel 10 near the breeding tank 14 by bolts or welding. The other end of the reinforcing block 9 is fixedly connected to the outer wall of the lower fixing sleeve 7. The lower fixing sleeve 7 is a ring-shaped component, and its top is connected by a connecting rod or directly... The device has an upper fixing sleeve 8 and an upper fixing sleeve 7 together fixing a cylindrical protective sleeve 6. The inner diameter of the protective sleeve 6 is slightly larger than the outer diameter of the breeding tank 14, so that it can fit on the outer wall of the breeding tank 14 and slide smoothly up and down. In order to ensure the sealing of the breeding tank 14 in the non-released state and the stability during the lifting process, this device is designed with multiple sealing and limiting structures. On the inner side of the lower fixing sleeve 7 and the upper fixing sleeve 8, there are annular sealing rings 16. The sealing rings 16 are made of wear-resistant and elastic rubber or silicone material. When the protective sleeve 6 is fitted on the breeding tank 14, the inner wall of the sealing ring 16 fits tightly with the outer wall of the breeding tank 14, forming the first dynamic seal to prevent insects from escaping from the gap between the protective sleeve 6 and the breeding tank 14. On the inner side of the sealing ring 16, multiple arc-shaped limiting pads 17 are also fixedly installed. These arc-shaped limiting pads 17 are evenly distributed along the circumference, with their inner surfaces in contact with the outer wall of the breeding tank 14. They are made of engineering plastics with self-lubricating properties, such as nylon or polytetrafluoroethylene. Their function is to reduce friction between the protective cylinder 6 and the breeding tank 14 during lifting and lowering, and to precisely limit the radial position of the protective cylinder 6, ensuring it remains concentric with the breeding tank 14. On the inner side of each arc-shaped limiting pad 17, multiple elastic scraping rods 18 are fixedly installed. These elastic scraping rods 18 are made of materials with good elasticity, such as polyurethane rubber, spring steel sheets, or nylon rods, with their ends inclined towards the rotation direction of the breeding tank 14. When the breeding tank 14 rotates, these stationary elastic scraping rods 18 continuously and gently sweep across the outer surface of the breeding tank 14.

[0018] It should be noted that this utility model is a directional release device for natural enemy insects of the tea oleifera stem borer. In use, before starting work, the control system, such as a PLC controller or microcontroller, drives the motor on the lifting screw 12, causing the moving panel 10 to move the entire lifting assembly, including the reinforcing block 9, lower fixing sleeve 7, upper fixing sleeve 8, and protective cylinder 6, to its highest position. At this time, the protective cylinder 6 completely covers all the release ports 15 on the side wall of the breeding tank 14, and is in a sealed standby state. The operator opens the upper sealing cylinder 13 and pours the cultivated natural enemy insects, such as parasitic wasps, into the tank through the opening at the top of the breeding tank 14. After loading, the upper sealing cylinder 13 is closed again to ensure a relatively closed environment inside the breeding tank 14, protecting the insects during transportation and standby. The control system activates the motor inside the rotating seat 3, which drives the breeding tank 14 to rotate slowly and uniformly via the rotating shaft. The purpose of rotation is to use centrifugal force and gravity to evenly disperse the predatory insects gathered inside the tank and allow them to move naturally towards the tank wall, closer to the release port 15, in preparation for subsequent release. Upon receiving the release command, the control system activates the drive motor of the lifting screw 12, which begins to rotate. Through the threaded engagement with the slider on the moving panel 10, the moving panel 10 is driven to move smoothly downwards along the guide rail of the support frame 2. The moving panel 10, through the reinforcing block 9, drives the lower fixed sleeve 7 and the upper fixed sleeve 8 to descend synchronously. Since the protective cylinder 6 is fixedly connected to the upper and lower fixed sleeves 7, the entire protective cylinder 6 begins to slide downwards along the outer wall of the rotating breeding tank 14. As the protective cylinder 6 moves downward, its upper edge gradually reveals the release port 15 on the breeding tank 14. Once the release port 15 is exposed from the cover of the protective cylinder 6, the natural enemy insects that are close to these openings will fly out of the release port 15 quickly due to their phototaxis, activity instinct, and centrifugal force brought by rotation, and enter the natural environment to find the host, the tea oleifera stem borer. By controlling the downward stroke of the lifting screw 12, the number and area of ​​the release port 15 exposed by the protective cylinder 6 can be precisely controlled. The longer the downward distance, the more release ports 15 are exposed, and the more insects are released per unit time, thus achieving controllable adjustment of the release amount. As the rearing tank 14 continues to rotate, some slow-moving or larger insects may get stuck at the release port 15 and be unable to fly out smoothly. At this point, multiple elastic scraping rods 18 installed inside the arc-shaped limiting pad 17 begin to play a crucial role. Since the elastic scraping rods 18 are stationary while the rearing tank 14 is rotating, relative motion occurs between them. When the rotating wall of the rearing tank 14 passes the elastic scraping rods 18, the rods, like windshield wipers, gently but forcefully sweep across the edge of the release port 15. The elastic material of the scraping rods 18, upon contact with the stuck insects, produces a certain degree of elastic deformation, providing sufficient thrust to push the insects back into the rearing tank 14 without being too hard and damaging them. The insects scraped back can then have another chance to fly out from other release ports 15 during subsequent rotations, greatly improving the insect release success rate and reducing unnecessary waste. The lifting screw 12 rotates in the opposite direction, driving the moving panel 10 and the entire lifting assembly to move upward, so that the protective cylinder 6 covers all the release ports 15 again, restoring the sealing state. The motor of the rotating seat 3 stops working, and the breeding tank 14 stops rotating.
