[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a device for collecting and removing thrips from the top of tobacco plants, comprising:

[0028] Adjusting handle 1, and adsorption mechanism 2 set at one end of adjusting handle 1 to adsorb thrips. A flow guiding mechanism 4 connected to adsorption mechanism 2 is set on adjusting handle 1. A filter mechanism 3 for filtering large particles is set between flow guiding mechanism 4 and adsorption mechanism 2.

[0029] The other end of the adjusting handle 1 is equipped with a collection mechanism 7 for collecting thrips, and the collection mechanism 7 is connected to the flow guiding mechanism 4 through the adjusting handle 1. The other end of the adjusting handle 1 is equipped with a vortex fan 5, which extracts air from the adsorption mechanism 2 to collect thrips.

[0030] The collection mechanism 7 includes an installation cylinder 71, a filter collection screen cylinder 75, and a cover 77. The cover 77 is provided with an installation tube 78 connected to the installation cylinder 71. Multiple sets of ultraviolet lamps 8 are provided on the inner top of the cover 77. An inner ring 72 supporting the filter collection screen cylinder 75 is fixedly connected inside the installation cylinder 71, and multiple sets of positioning blocks 74 are fixedly connected on the inner ring 72. The filter collection screen cylinder 75 is provided with insertion holes 76 for the multiple sets of positioning blocks 74 to be inserted. An air duct 73 connected to the vortex fan 5 is provided on the outside of the installation cylinder 71. Multiple sets of quick-release mechanisms 9 for connection are provided between the installation cylinder 71 and the cover 77.

[0031] In this embodiment, the collected thrips can be killed by the ultraviolet lamp 8 (ultraviolet sterilization lamp), thus preventing the collected thrips from surviving. At the same time, the quick-release mechanism 9 facilitates the quick disassembly of the installation cylinder 71, making it convenient to put in and take out the filter collection cylinder 75, and thus facilitating the cleaning of the collected thrips. The aperture of the filter collection cylinder 75 is smaller than the volume of the thrips, thus preventing the thrips from escaping. Regular cleaning is used to prevent the filter collection cylinder 75 from becoming clogged. A sealing gasket (not shown in the figure) is provided at the connection end between the installation cylinder 71 and the cover 77 to ensure the airtightness of the extraction. Under the strong suction of the vortex fan 5 (existing technology, not described in detail), the air inlet end of the adsorption mechanism 2 can generate suction, thus facilitating the adsorption of thrips.

[0032] The quick-release mechanism 9 includes a guide tube 91 fixedly connected to the outside of the cover 77. A connecting rod 93 is slidably inserted into the guide tube 91. A lever 92 is fixedly connected to one end of the connecting rod 93 inside the cover 77. A locking block 96 is fixedly connected to the lower end of one side of the lever 92. A slot 79 for the locking block 96 to be inserted is opened on the inner wall of the mounting tube 71. A spring 94 located inside the guide tube 91 is sleeved on the outside of the connecting rod 93. A button 95 that slides inside the guide tube 91 is fixedly connected to the other end of the connecting rod 93.

[0033] In a further preferred embodiment, by applying pressure to the button 95, the button 95 drives the toggle block 92 on the connecting rod 93 to move, so that the locking block 96 on the toggle block 92 disengages from the locking groove 79, thereby releasing the fastening of the mounting cylinder 71, making it easier to remove the mounting cylinder 71 and clean the thrips, thus improving the convenience of disassembly and assembly.

[0034] The adsorption mechanism 2 includes an expanding mask 21 and a silicone cover plate 22. The outer side of the expanding mask 21 is fixedly connected with a number of first protrusions 23 for the silicone cover plate 22 to snap into. The bottom of the expanding mask 21 is provided with a guide bucket 26 connected to the impurity removal mechanism 3. The upper surface of the silicone cover plate 22 is provided with a number of adsorption holes 24, and the upper surface of the silicone cover plate 22 is fixedly connected with a number of second protrusions 25.

[0035] In a preferred embodiment, the first protrusion 23 facilitates the engagement of the silicone cover plate 22 with the flared end of the expanding mask 21. Simultaneously, the surface of the silicone cover plate 22 is provided with a silicone layer to prevent damage to the tobacco leaves when in contact with them, thus avoiding damage to the tender tissue at the top of the tobacco. The pore diameter of the adsorption hole 24 is greater than 4mm, ensuring that thrips are adsorbed into the expanding mask 21. The second protrusion 25 allows for a certain gap between the silicone cover plate 22 and the tobacco leaves, facilitating thrips adsorption and improving practicality.

[0036] The impurity removal mechanism 3 includes a temporary storage box 31. Side tubes 32 are provided on both sides of the temporary storage box 31, and connecting bolts 33 are threaded on the side tubes 32. A collection box 34 is inserted into the lower end of the side of the temporary storage box 31 adjacent to the two sets of side tubes 32. Two sets of buckles 35 that are snapped onto the collection box 34 are installed on the collection box 34. A filter screen is provided at the top inside the temporary storage box 31.

[0037] In a further embodiment, the filter screen prevents large particles from passing through. The filter screen has a pore size of less than 2 mm, which is only suitable for thrips and other debris smaller than 2 mm to pass through, thus facilitating the collection of thrips. The collection box 34 facilitates the collection of filtered large particles and allows for quick cleaning of debris with the action of the buckle 35. In the process of cleaning debris, it is also convenient to clean the filter screen, preventing debris from clogging the filter screen and improving the filtering effect.

[0038] The flow guiding mechanism 4 includes two sets of mounting seats 41, a straight pipe 42 and a bellows 43. The bellows 43 is located at one end of the straight pipe 42, and an insertion tube 44 is provided at one end of the bellows 43. The straight pipe 42 and the insertion tube 44 are respectively mounted on two sets of mounting seats.

[0039] In addition, the straight pipe 42 is inserted into the side pipe 32, and the air outlet of the guide bucket 26 is installed in the other side pipe 32. Both are fastened by connecting bolts 33. An O-ring is provided in the side pipe 32 to ensure the airtightness of the connection and prevent air leakage from affecting the negative pressure adsorption effect. The corrugated pipe 43 is designed to keep the air passage (reverse flow bucket, straight pipe 42 and connecting pipe 18) connected when the length of the adjustment handle 1 changes.

[0040] The adjusting handle 1 includes an outer rod 11 and an inner rod 13. The inner rod 13 is slidably inserted into one end of the outer rod 11. A handle 12 is fixedly connected to the outer side of the outer rod 11, and a locking bolt 14 is threadedly connected to one end of the outer side of the outer rod 11. Multiple sets of positioning holes 15 are opened on the outer side of the inner rod 13 for the locking bolt 14 to be inserted.

[0041] It is worth noting that the length of the inner rod 13 extending into the outer rod 11 can be adjusted to change the position of the adsorption mechanism 2, making it convenient to remove thrips from tobacco buds at different heights or distances, thus ensuring the thrips removal effect on the tobacco leaves. The handle 12 provides a force point for the user, thereby ensuring the stability of the handheld device.

[0042] The other end of the outer rod 11 is fixedly connected to a mounting plate 16 for mounting the vortex blower 5. A battery 6 is provided on one side of the mounting plate 16. A guide pipe 17 for threaded connection of the mounting pipe 78 is provided on the outer side of the outer rod 11 near the mounting plate 16. A connecting pipe 18 connected to the insertion pipe 44 is provided on the outer side of the guide pipe 17. An outer ring 19 is provided on the outer side of the guide pipe 17.

[0043] Specifically, the storage battery 6 can power the vortex fan 5 and the ultraviolet lamp 8, thereby increasing the continuous operating time of the device. At the same time, the storage battery 6 is detachable, which is convenient for replacement and improves practicality. An O-ring is provided in the connecting pipe 18 to ensure the airtightness of the connection between the flow guiding mechanism 4 and the flow guiding pipe 17. The outer side of the flow guiding pipe 17 is provided with an external thread (not shown in the figure) for threaded connection with the mounting pipe 78.

[0044] In use, the vortex fan 5 is operated to generate negative pressure, which causes the adsorption mechanism 2 to form suction. When removing thrips, the length of the inner rod 13 and outer rod 11 of the handle 1 is adjusted and locked according to the height of the tobacco plant, so that the expansion mask 21 of the adsorption mechanism 2 is close to the top surface of the plant. Under the action of suction, the thrips on the surface of the tobacco leaves are sucked into the expansion mask 21 through the adsorption holes 24 of the silicone cover plate 22. The second protrusion 25 increases the air circulation path so that the airflow can draw the thrips into the expansion mask 21 through the gaps, reducing the leakage.

[0045] Thrips are carried by the airflow through the guide bucket 26 into the impurity removal mechanism 3. The filter screen in the temporary storage box 31 intercepts large particles of impurities, which fall into the collection box 34 for cleaning. After filtration, the thrips pass through the straight pipe 42 and corrugated pipe 43 of the guide mechanism 4, and then through the guide pipe 17 into the collection mechanism 7. The thrips fall directly into the filter collection cylinder 75 and are killed by the ultraviolet lamp 8 on the cover 77. At the same time, the thrips are intercepted and retained by the filter collection cylinder 75. After the operation is completed, the button 95 of the quick release mechanism 9 drives the card block 96 to disengage from the card slot 79, and the cover 77 of the installation cylinder 71 can be removed to take out the thrips in the filter collection cylinder 75, which facilitates the cleaning of the thrips in the filter collection cylinder 75 and improves the overall thrips control effect in tobacco fields.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
