Description

Technical Field

[0001] This invention relates to the field of insect control equipment, specifically to a rotating bayberry fruit fly trapping and collection device. Background Technology

[0002] Adult fruit flies lay their eggs in crevices or breaks in the skin of bayberry fruits. After hatching, the larvae burrow into the fruit flesh to feed, causing holes and rot, and making the fruit surface uneven, directly damaging the fruit quality. To address this, existing technology includes a device for trapping fruit flies. For example, Chinese utility model patent CN214903247U discloses a fruit fly trap, comprising: a main body with an open cavity; a secondary body detachably connected to the main body, with a through-channel and a barrier, the first end of the channel connecting to the outside, the second end connecting to the cavity, the barrier located at the second end of the channel, and being elastic with a unidirectional elastic deformation design, extending from the channel into the cavity; and a trapping component, one end of which is detachably connected to the bottom of the secondary body, the other end of which holds a solid-liquid attractant, and the trapping component is located inside the cavity.

[0003] However, existing trapping devices of this type generally adopt an integrated design of trapping and collection structures, that is, integrating the trapping component carrying the attractant with the collection chamber that holds the fruit flies in the same space. This design has room for improvement. On the one hand, after the captured fruit flies die in the chamber, they come into direct contact with the attractant on the trapping component. In the high temperature and humidity environment of bayberry producing areas, the insects decompose rapidly, and their metabolites and putrefactive fluids contaminate the attractant, destroying its original components and activity, causing the attractant to become ineffective at a significantly faster rate, thereby reducing the continuous trapping efficiency of the device. On the other hand, the putrefied insects mixed with the attractant will adhere to the inner wall of the chamber and the surface of the trapping component, forming a sticky contaminant. This not only increases the difficulty of cleaning the device, but also requires frequent disassembly and maintenance to avoid further contamination, resulting in poor ease of use and high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a rotating fruit fly trapping and collecting device for bayberries. This invention effectively maintains fruit fly trapping efficiency by separating the fly trapping structure from the collecting structure, facilitating cleaning and maintenance of the device, and making it easy to use.

[0005] The technical solution of this invention: A rotating bayberry fruit fly trapping and collecting device includes a main rod with a supporting body on the main rod. One end of the supporting body has a trapping platform with a central frame on the trapping platform. Multiple channel tubes are provided on the side of the central frame to lure fruit flies into the central frame. A collection port is provided on the platform surface of the trapping platform, with its upper part connected to the central frame. The lower part of the trapping platform has a collection bucket corresponding to the collection port. A pusher is provided inside the central frame, with a component platform at its movable end. The size of the component platform corresponds to the internal size of the central frame. A rotation drive component is provided on the component platform, with a box frame at its rotating end, corresponding to the collection port. An extension and removal drive component is provided on the box frame, with multiple box cavities on its circumference. A box cover is provided at the opening of each box cavity via a torsion spring structure. A trapping box is provided at the movable end of the extension and removal drive component, positioned within a box cavity. The box cover is used to seal the opening of the trapping box.

[0006] In the aforementioned rotary bayberry fruit fly trapping and collecting device, the supporting body includes a base, one side of which is provided with a surrounding member that encircles the main body rod, and the plate of the base is provided with multiple bolts; the side of the main body rod is provided with multiple positioning holes, and the bolts cooperate with the positioning holes.

[0007] In the aforementioned rotary bayberry fruit fly trapping and collecting device, the opening of the collecting bucket is connected to the lower part of the trapping platform via a thread.

[0008] In the aforementioned rotary bayberry fruit fly trapping and collecting device, the rotary drive assembly includes a motor bracket mounted on the assembly platform, a drive motor mounted on the motor bracket, a drive gear mounted on the output end of the drive motor, and the upper end of the box frame being sleeved on the shaft of the assembly platform via a bearing. A driven gear meshing with the drive gear is mounted on the shaft.

[0009] In the aforementioned rotary bayberry fruit fly trapping and collecting device, the central frame includes a bottom body and a top body set on the trapping platform, and a pusher is set on the lower surface of the top body; the bottom body includes an outer body set on the trapping platform, and the outer body has multiple fixed cylinders inside, one end of the fixed cylinder has an inner plate, the inner plate is fixed to the fixed cylinder by screws, and the multiple inner plates are sequentially assembled to form the internal space of the central frame.

[0010] In the aforementioned rotary bayberry fruit fly trapping and collecting device, the extended removal drive component includes a positioning frame mounted on a box frame, a shaft passing through the center of the positioning frame, a first gear connected to a drive motor mounted on the positioning frame, and a second gear meshing with the first gear mounted on the shaft. The positioning frame has multiple sliding rods mounted via sliding grooves, and the second gear is connected to the inner end of the sliding rods via a limiting structure. The trapping box is mounted on the outer end of the sliding rods.

[0011] In the aforementioned rotary bayberry fruit fly trapping and collecting device, the inner side of the box cover door has a sealing strip, which fits into the opening of the trapping box.

[0012] Compared with the prior art, the present invention has the following advantages: 1. In this invention, the inner wall of the trapping box is coated with a trapping agent, and the collection bucket is coated with glue. Initially, the trapping box is placed inside the central frame. When the extension and removal drive is activated, the trapping box touches the box cover door, causing the box cover door to deflect and open, exposing the trapping agent inside. Fruit flies enter the central frame through the channel tube and attach to the trapping box. After a period of time, a certain number of fruit flies accumulate in the trapping box. The extension and removal drive is reset, the box cover door rotates back to seal the opening end of the trapping box, the pusher is activated, the component platform moves downward, and the trapping box moves into the collection bucket. Immediately afterwards, the extension and removal drive is activated again, opening the box cover door. When the door opens, the rotary drive unit activates, causing the trap box to rotate. The centrifugal force generated by the rotation throws the fruit flies into the collection bucket. Because the collection bucket is coated with glue, the fruit flies adhere to the inner wall of the collection bucket. Finally, the extension drive unit and the lid door reset, the pusher retracts, and the trap box returns to the central frame. By separating the fruit fly trapping structure from the collection structure, the fruit flies will not be in prolonged contact with the attractant after being trapped, maintaining the activity of the attractant and slowing down its deterioration. Secondly, the rotating structure throws the fruit flies into the collection bucket, avoiding the presence of insects in the trap box and facilitating subsequent cleaning and maintenance.

[0013] 2. In the extended removal starter, the motor drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear achieves the radial movement of the sliding rod through the limiting structure. The trap box is connected to the outer end of the sliding rod. The extension and retraction of the sliding rod can simultaneously touch the box cover to achieve automatic opening. The reset action, in conjunction with the torsion spring structure, drives the box cover to automatically close. There is no need to set up an additional independent opening drive structure.

[0014] 3. The inner side of the box lid has a sealing strip, which fits into the opening of the trap box. The sealing strip enables the box lid to effectively seal the trap box, ensuring that the fruit flies can move smoothly into the collection bucket. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: A rotating fruit fly trapping and collecting device for bayberries, including a main body rod 1, as shown in the attached diagram. Figure 1 As shown, a supporting body 2 is installed on the main rod 1, a trapping platform 3 is installed at one end of the supporting body 2, and a central frame 4 is installed on the trapping platform 3, as shown in the attached diagram. Figure 2 As shown, the side of the central frame 4 is provided with multiple channel tubes 5 to lure fruit flies into the central frame 4. The channel tubes are fixedly installed on the trapping platform. Fruit flies will enter the central frame along the channel tubes. The trapping platform 3 has a collection port 6 on its surface. The upper part of the collection port 6 is connected to the central frame 4. The lower part of the trapping platform 3 has a collection bucket 7 corresponding to the collection port 6. The mouth of the collection bucket 7 is connected to the lower part of the trapping platform 3 by a thread. The threaded connection makes it easy to remove the collection bucket from the lower part of the trapping platform and process the fruit flies collected in the bucket, which is convenient and quick. The central frame 4 is equipped with a pusher 8, which is an electric push rod. The movable end of the pusher 8 is provided with a component platform 9. The size of the component platform 9 corresponds to the internal size of the central frame 4. The central frame 4 includes a bottom body 27 and a top body 28 set on the trapping platform 3, as shown in the attached figure. Figure 4As shown, the pusher 8 is set on the lower surface of the top body 28; the bottom body 27 includes an outer body 29 set on the trapping platform 3. Multiple fixing cylinders 30 are installed inside the outer body 29. One end of the fixing cylinder 30 is provided with an inner plate 31. The inner plate 31 is fixed to the fixing cylinder 30 by screws. Multiple inner plates 31 are sequentially assembled to form the internal space of the central frame 4. The inner plate will come into contact with fruit flies and will accumulate a lot of dirt after long-term use. To facilitate cleaning, an assembly structure is adopted to facilitate the disassembly of the inner plate. The initial position of the assembly platform is flush with the upper surface of the bottom body, making the central frame a relatively closed space, making it difficult for fruit flies to fly out. A rotary drive assembly 10 is provided on the component platform 9. A box frame 11 is provided at the rotating end of the rotary drive assembly 10, corresponding to the collection port 6. An extension and removal drive component 12 is provided on the box frame 11. Multiple box cavities 13 are located on the circumferential side of the box frame 11. A box cover 14 is provided at the opening of each box cavity 13 via a torsion spring structure. One end of the box cover 14 is hinged to the opening side of the box cavity via a torsion spring. A trapping box 15 is installed on the movable end of the extension and removal drive component 12, as shown in the attached diagram. Figure 6 As shown, the inner side of the lid 14 has a sealing strip, which fits into the opening of the trap box 15. When driven by the expansion and removal drive, the trap box contacts the lid, causing it to deflect and open. After the trap box returns to its original position, the lid rotates back to seal it. This provides temporary storage for fruit flies when the trap box moves into the collection bucket. The trap box 15 is positioned within the box cavity 13, and the lid 14 seals the opening of the trap box 15. When the trap box moves into the collection bucket, the radius between the center of the box frame and the outer side of the lid is slightly smaller than the radius of the collection opening, allowing the trap box to move smoothly. The inner surface of the trap box is coated with a trapping agent. The core components of this agent are a mixture of fresh bayberry juice, brown sugar, edible vinegar, and yeast extract in a specific ratio, with a small amount of agar added to form a gel. This attractant utilizes the strong attraction of bayberry fruit flies to the volatiles and sweet-sour aroma of bayberry fruit, resulting in precise attraction. Its gel form prevents leakage of the liquid attractant during the device's rotation and expansion, while also allowing for slow release of the aroma, extending the effective trapping period. The attractant coating inside the trapping box is relatively thin, making it difficult for the attractant to be thrown out when the box rotates. The inner wall of the collection bucket is coated with a high-viscosity, weather-resistant, pressure-sensitive insect-specific adhesive. This type of adhesive is resistant to high temperatures and humidity, and will not quickly dry out or lose its stickiness in the hot and rainy summer conditions of bayberry-producing areas, nor will it lose its stickiness due to moisture. The adhesive has a moderate viscosity, allowing fruit flies to adhere instantly after being thrown into the collection bucket by centrifugal force, preventing escape and avoiding cleaning difficulties caused by excessive viscosity.

[0019] The supporting body 2 includes a base 16, and one side of the base 16 has a surrounding member 17 that encircles the main body rod 1, as shown in the attached figure. Figure 3As shown, multiple bolts 18 are installed on the plate of the base 16; the side of the main rod 1 has multiple positioning holes 20, and the bolts 18 cooperate with the positioning holes 20. The supporting body surrounds the main rod through the enclosing part, and the bolts on the base cooperate with the positioning holes at different heights on the side of the main rod, so that the installation height of the supporting body and the trapping platform above can be freely adjusted. This design can adapt to bayberry trees of different ages and heights, and accurately place the trapping structure in the core area of ​​fruit fly activity, effectively improving the trapping efficiency and solving the problems of fixed height and poor adaptability of traditional trapping devices.

[0020] The rotary drive assembly 10 includes a motor bracket 21 mounted on the assembly platform 9, as shown in the attached figure. Figure 5 As shown, a drive motor 22 is mounted on the motor bracket 21. The output end of the drive motor 22 is connected to a drive gear 23. The upper end of the box frame 11 is sleeved on the shaft 24 of the component platform 9 via a bearing. A driven gear 25 that meshes with the drive gear 23 is mounted on the shaft 24. After the drive motor outputs power, it drives the drive gear to rotate, and the drive gear drives the driven gear to rotate. The shaft at the upper end of the box frame is connected to the driven gear, realizing the rotation of the box frame and its components.

[0021] The extended removal drive 12 includes a positioning bracket 32 ​​disposed on the box frame 11, as shown in the attached figure. Figure 7 As shown, the shaft 24 passes through the center of the positioning frame 32. The positioning frame 32 is equipped with a first gear 33 connected to the drive motor, and the shaft 24 is equipped with a second gear 34 that meshes with the first gear 33. Multiple sliding rods 35 are mounted on the positioning frame 32 via sliding grooves. The second gear 34 is connected to the inner end of the sliding rod 35 via a limiting structure. This limiting structure mainly includes a column on the inner end of the sliding rod and multiple arc-shaped grooves evenly arranged around the center of the second gear. The column is embedded in the arc-shaped grooves, and the trapping box 15 is located at the outer end of the sliding rod 35. The rotation of the first gear connected to the motor drives the second gear to rotate. The inner end of the sliding rod has a column, and the second gear has an arc-shaped groove that mates with the column. Through this structure, when the second gear rotates, it controls the sliding rod to move along the sliding groove direction within the positioning frame, thereby enabling the trapping box to move in and out of the box cavity. The cross-section of the box cavity is a fan-shaped structure, and the cross-section of the trapping box is also fan-shaped, which corresponds to the box cavity. Taking the upper surface of the second gear as an example, when the second gear rotates clockwise, the column slides along the outer end of the arc groove, thereby extending the sliding rod and moving the trap box out of the box cavity; conversely, when the second gear rotates counterclockwise, the column slides along the inner end of the arc groove, thereby retracting the sliding rod and returning the trap box to the box cavity.

[0022] The working principle of this invention: After the device is installed, the enclosure 17 of the supporting body 2 and the bolt 18 are used to align with the positioning hole 20 of the main body rod 1 to adjust the trapping platform 3 to the height of the fruit fly activity core. At this time, all components are in the initial standby state, the pusher 8 retracts, the assembly platform 9 is flush with the upper end surface of the bottom body 27 of the central frame 4, and the central frame 4 forms a sealed space. The channel pipe 5 is connected to the interior of the central frame 4, forming the only entry channel for the fruit fly. The drive motor 22 drives the first gear 33 on the positioning frame 32 to rotate, and the first gear 33 meshes with the second gear 34 on the drive shaft 24. Wheel 34 engages with the inner end column of sliding rod 35 via an arc groove, pushing sliding rod 35 radially outward along the groove of positioning frame 32. Simultaneously, the trapping box 15 at the outer end of sliding rod 35 moves outward, touching the box cover 14 at the opening of box cavity 13, causing the torsion spring to deform elastically. The box cover 14 deflects and opens, exposing the gel-like attractant inside trapping box 15. Its volatile sweet and sour odor diffuses to the outside through channel tube 5, attracting fruit flies along channel tube 5 into the interior of central frame 4 using the attraction of the attractant. Attracted by the attractant, fruit flies attach to the inner wall of trapping box 15, completing the trapping and aggregation process. When the trapping box 15 is filled with fruit flies... After a certain number of fruit flies gather, the expansion and removal drive 12 reverses, the sliding rod 35 retracts, and the trap box 15 returns to the box cavity position 13 along with the sliding rod 35. The torsion spring returns to its original deformation, causing the box cover door 14 to rotate and close. The sealing strip re-adheres the opening of the trap box 15, temporarily sealing the fruit flies inside the trap box 15. The pusher 8 then extends downwards, causing the component platform 9, the rotation drive component 10, the box frame 11, and the sealed trap box 15 to move downwards synchronously, passing through the collection port 6 of the trap platform 3, and finally allowing the trap box 15 to enter the collection bucket 7 connected by threads below. After entering the collection bucket 7, the process is initiated. In the separation process between the fruit flies and the trap box 15, the drive motor 22 of the rotary drive assembly 10 is started, and the output active gear 23 meshes with the driven gear 25 on the shaft 24, driving the shaft 24 and the box frame 11 to rotate at high speed. Simultaneously, the extension and removal drive component 12 is started, the sliding rod 35 extends again, and the box cover door 14 is pushed open by the trap box 15. The opening of the trap box 15 is exposed inside the collection bucket 7. The centrifugal force generated by the rotation acts on the fruit flies inside the trap box 15, throwing them off the inner wall of the trap box 15. The fruit flies are directly thrown onto the inner wall of the collection bucket 7; the weather-resistant pressure-sensitive adhesive on the inner wall of the collection bucket 7 instantly adheres to the fruit flies.
