Description

Technical Field

[0001] The utility model relates to the technical field of pest trapping, in particular to a citrus psyllid trapping device. Background Technique

[0002] Citrus psyllid is the main pest in the new shoot stage of citrus and also the transmission vector of citrus huanglongbing. Adult psyllids mostly lay eggs on the tender shoots of the host. After hatching into nymphs, they suck the sap of the tender shoots until they emerge as adults. The damaged tender shoots of the host can show wilting, distortion of new shoots, etc. The psyllids also secrete white honeydew and adhere to the branches and leaves, which can cause the occurrence of sooty mold. Even worse, psyllids feed, lay eggs and reproduce on citrus huanglongbing-infected plants, producing a large number of adult bacteria-carrying psyllids. The adult psyllids can spread huanglongbing by transferring to harm new plants.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0034] Please refer to Figures 1 to 7 , a citrus psyllid trapping device, including a collection chamber 1 and a shielding cover 2. The collection chamber 1 is used to collect the corpses of citrus psyllids. The shielding cover 2 is connected to the collection chamber 1 in a movable mounting manner, and the connection method between the two can be in ways such as threads, buckles, etc. Since it is prior art, it will not be elaborated here.

[0035] A connecting column 3 is fixedly installed on the shielding cover 2, and a waterproof cover 4 is fixedly installed on the connecting column 3. The presence of the waterproof cover 4 can prevent rainwater from invading the inside of the collection chamber 1 and causing unnecessary pollution activities.

[0036] A suspension member 5 and an insect attracting source 6 are provided on the waterproof cover 4. Preferably, the suspension member 5 can be a hook, a rope, or other structures that can conveniently place the entire device at the corresponding height on the citrus tree. The insect attracting source 6 is a device containing the pheromone corresponding to citrus psyllids, which is used to attract citrus psyllids into the inside of the collection chamber 1, thereby realizing the trapping activity, and the insect attracting source 6 can be quickly removed for replenishment activities.

[0037] A fixed bottom plate 10 is fixedly installed at the bottom of the collection chamber 1. A fixed block 17 is fixedly installed on the fixed bottom plate 10. A fixed baffle plate 12 is movably installed on the fixed block 17 and can be disassembled, so as to facilitate further careful cleaning when the use time is too long.

[0038] A rotating block 15 is rotatably installed at the center of the fixed bottom plate 10. A rotating bottom plate 11 is fixedly installed on the rotating block 15. A limiting component 19 is arranged at the bottom of the rotating bottom plate 11.

[0039] The limiting component 19 can control the rotation of the rotating bottom plate 11, so as to ensure that there is no gap between the rotating bottom plate 11 and the fixed bottom plate 10 usually, and prevent the accidental escape of Diaphorina citri.

[0040] By rotating the rotating bottom plate 11, the rotating bottom plate 11 and the fixed bottom plate 10 gradually coincide. At this time, the space originally blocked by the rotating bottom plate 11 can be exposed, and the corpses of Diaphorina citri can be exposed through this channel, so as to realize the rapid collection activity.

[0041] A rotating rod 13 is fixedly installed at the center of the rotating block 15. A driving plate 14 is fixedly installed on the rotating rod 13.

[0042] In the initial state, the driving plate 14 is in contact with the fixed baffle plate 12. When the rotating bottom plate 11 is rotated, the rotating rod 13 will rotate, and then the driving plate 14 will move synchronously. The movement of the driving plate 14 can push the corpses of Diaphorina citri on the fixed bottom plate 10 to move, so that they can fall smoothly through the exposed channel.

[0043] The existence of the fixed baffle plate 12 can prevent the corpses of Diaphorina citri that can be driven from re-entering the space on the fixed bottom plate 10, so as to ensure the cleaning effect.

[0044] The limiting component 19 includes a connecting rod 20 and a pressing rod 24. The connecting rod 20 is fixedly connected to the bottom of the rotating bottom plate 11. A fixed cylinder 21 is fixedly installed on the connecting rod 20. A moving cylinder 23 is fixedly installed on the pressing rod 24. The moving cylinder 23 slides inside the fixed cylinder 21.

[0045] A spring 22 is fixedly installed inside the fixed cylinder 21. The other end of the spring 22 is fixedly installed on the side of the moving cylinder 23 facing the fixed cylinder 21.

[0046] By applying a certain pressure to the pressing rod 24, the spring 22 is compressed, and the moving cylinder 23 enters the fixed cylinder 21. At this time, the distance between the connecting rod 20 and the pressing rod 24 will become closer, so that the entire limiting component 19 can move, and then drive the rotating bottom plate 11 to rotate.

[0047] A fixing ring 8 is fixedly installed at the bottom of the collecting chamber 1, and a slide groove 25 is provided on the fixing ring 8 for the compressed limit assembly 19 to slide. When the distance between the connecting rod 20 and the pressing rod 24 becomes closer (that is, the overall height of the limit assembly 19 is lower), the limit assembly 19 can move smoothly in the slide groove 25, thereby causing the rotating bottom plate 11 to rotate, completing the opening and closing activities of the channel.

[0048] The fixing ring 8 is provided with limiting grooves 26 on both side edges of the sliding groove 25 for accommodating the pressing rod 24 .

[0049] When the limit assembly 19 is at the edge of the slide groove 25, the force applied to the pressing rod 24 is cancelled. Under the action of the spring 22, the movable cylinder 23 moves out of the fixed cylinder 21, and then the distance between the connecting rod 20 and the pressing rod 24 increases. The pressing rod 24 is located on the limit groove 26, so that the limit assembly 19 cannot move, thereby ensuring the continuous opening or closing of the channel.

[0050] Two hooks 7 are fixedly mounted on the collecting chamber 1, and the two hooks 7 are arranged at 180 degrees.

[0051] The hook 7 can be used to hang bags containing citrus psyllid corpses. It is worth noting that the bottom space of the collection chamber 1 needs to be completely inside the bag opening to achieve complete collection activities, and then on-site incineration can be carried out.

[0052] A scraper sleeve 16 is inlaid and installed on the driving plate 14 , and the scraper sleeve 16 is in direct contact with the inner wall of the collecting chamber 1 and the upper surface of the rotating bottom plate 11 .

[0053] When the driving plate 14 rotates, the scraping sleeve 16 can scrape off impurities such as broken limbs and corpses on the inner wall of the collection chamber 1 and the upper surface of the rotating bottom plate 11, thereby ensuring the cleanliness of the interior of the collection chamber 1 as much as possible and ensuring the collection effect.

[0054] The fixed bottom plate 10 and the rotating bottom plate 11 are both semicircular, and the two can together form a circle with the same size as the bottom cross-section of the collecting chamber 1 .

[0055] A cleaning brush 18 is fixedly mounted on one side of the fixing block 17 facing the rotating bottom plate 11 , and the cleaning brush 18 abuts against the rotating bottom plate 11 .

[0056] When the rotating bottom plate 11 rotates, the cleaning brush 18 moves relative to the rotating bottom plate 11, so that the cleaning brush 18 can clean the scum on the rotating bottom plate 11 without moving with the rotating bottom plate 11, and then the scum can fall smoothly through the exposed channel.

[0057] A guiding plate 9 is fixedly installed on the shielding cover 2, and an inverted conical insect inlet channel is arranged inside the guiding plate 9. This setting can effectively prevent the Asian citrus psyllid from flying out, thus ensuring the trapping effect.

[0058] The working process of the present utility model: First, the entire device is placed at the corresponding height on the citrus tree through the hanging member 5, and then the trapping activity is carried out. When it is time to clean, the bag for containing the corpses of Asian citrus psyllids is hung through the two hooks 7. It should be noted that the bottom space of the collection chamber 1 needs to be completely inside the opening of the bag.

[0059] By applying a certain pressure to the pressing rod 24, the spring 22 is compressed, and the moving cylinder 23 enters the fixed cylinder 21. At this time, the distance between the connecting rod 20 and the pressing rod 24 will become closer, so that the entire limiting component 19 can move, and then drive the rotating bottom plate 11 to rotate.

[0060] By rotating the rotating bottom plate 11, the rotating bottom plate 11 and the fixed bottom plate 10 gradually coincide. At this time, the space originally blocked by the rotating bottom plate 11 can be exposed, and the corpses of Asian citrus psyllids can fall directly into the bag for containing the corpses of Asian citrus psyllids through this channel after being exposed, so that rapid collection activities can be realized.

[0061] And when the rotating bottom plate 11 is rotated, the rotating rod 13 will rotate, and then the driving plate 14 will move synchronously. The movement of the driving plate 14 can push the corpses of Asian citrus psyllids on the fixed bottom plate 10 to move, so that they can fall smoothly through the exposed channel.

[0062] When the driving plate 14 rotates, the scraping edge sleeve 16 can scrape off impurities such as severed limbs and corpses on the inner wall of the collection chamber 1 and the upper surface of the rotating bottom plate 11, so as to ensure the cleanliness inside the collection chamber 1 as much as possible and ensure the collection effect.

[0063] After cleaning, by applying a certain pressure to the pressing rod 24 to make it move in the reverse direction, when it is at the edge of the corresponding sliding groove 25, the force applied to the pressing rod 24 is cancelled. Under the action of the spring 22, the pressing rod 24 is located on the limiting groove 26, making the limiting component 19 unable to move. At this time, there is no gap between the rotating bottom plate 11 and the fixed bottom plate 10, which can prevent the accidental escape of Asian citrus psyllids.

[0064] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
