[0032] 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.
[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a high-efficiency gray planthopper screening and separating device, comprising a housing 1. A trapping lamp 2 is provided on the right side wall of the housing 1. The trapping lamp 2 is existing technology; it emits light of a specific wavelength to attract gray planthoppers into the interior of the housing 1. A connecting frame 3 is slidably connected to the inner side wall of the housing 1. Guide blocks are provided on both sides of the connecting frame 3, allowing the entire connecting frame 3 to slide outward from the interior of the housing 1. A sieve is detachably installed on the inner wall at the top of the connecting frame 3 via a limiting component 4. The outer sidewall of the collection box 5 and the inner sidewall of the connecting frame 3 are in contact. A cavity is opened on the surface of the shell 1. The outer wall of the collection box 5 is in contact with the inner wall of the cavity. Small through holes are opened on the sidewalls of both sets of collection boxes 5, so that the fan 6 can generate suction to draw the gray planthoppers attracted by the trapping lamp 2 into the interior of the two sets of collection boxes 5, so that they can be trapped and screened. The fan 6 is provided on the left sidewall of the shell 1, and the surface of the collection box 5 is provided with an automatic opening and closing mechanism 7.
[0034] Reference Figure 2 - Figure 4 A rotating block 8 is rotatably connected to the inner wall of the housing 1, and a locking block 9 is rotatably connected to the center of the connecting frame 3. A vertical groove is provided at the center of the housing 1, and the outer wall of the locking block 9 contacts the inner wall of the vertical groove of the housing 1. A positioning groove is provided on the surface of the rotating block 8, and the end of the locking block 9 is inserted into the inner wall of the positioning groove of the rotating block 8. The locking block 9 can rotate within the inner wall of the connecting frame 3, allowing its end guide block to insert into the vertical groove penetrating the housing 1 and into the inner wall of the positioning groove of the rotating block 8. Reverse rotation of the locking block 9 will cause the rotating block 8 to rotate synchronously, and the end guide block of the locking block 9 will contact the side wall of the housing 1, thus fixing the connecting frame 3 to the surface of the housing 1, thereby securing the two sets of screening and collecting boxes 5. The installation position is supported by a limiting component 4, which includes a rod 42. The rod 42 is elastically connected to the inner wall of the top of the connecting frame 3 via a limiting spring 41. One end of the limiting spring 41 is fixedly connected to the surface of the rod 42, and the other end is fixedly connected to the inner wall of the connecting frame 3. The function of the limiting spring 41 is to automatically reset the position of the rod 42 after it is pulled outward. The rod 42 passes through and slides on the inner wall of the top of the connecting frame 3. A through hole is provided at the top of the connecting frame 3. The bottom end of the outer wall of the rod 42 is inserted into the inner wall of the through hole. The insertion between the two allows the screening and collection box 5 to be installed and fixed to the inner wall of the connecting frame 3, thereby enabling the screening and collection of planthoppers.
[0035] Reference Figure 2 and Figure 5The automatic opening and closing mechanism 7 includes a sliding plate 71. The top end of the sliding plate 71 is elastically connected to the inner wall of the top of the screening and collecting box 5 via a return spring 72. One end of the return spring 72 is fixedly connected to the outer wall of the top of the sliding plate 71, and the other end is fixedly connected to the inner wall of the top of the screening and collecting box 5. The function of the return spring 72 is to automatically reset the position of the sliding plate 71 and the contact block 74 after the contact block 74 is released from contact with the side wall of the housing 1. A guide rod 73 is slidably connected through the inner wall of the top of the sliding plate 71. The guide rod 73 guides the movement of the sliding plate 71. A contact block 74 is fixedly connected to the surface of the housing 1. The outer wall of the contact block 74 is in contact with the surface of the housing 1. The contact between the two causes the contact block 74 to be contacted by the surface of the housing 1 when the screening and collecting box 5 is installed on the inner wall of the connecting frame 3 and enters the interior of the housing 1. This causes the sliding plate 71 to slide open on the surface of the screening and collecting box 5 to facilitate the collection of gray planthoppers. At the same time, when the screening and collecting box 5 is removed from the fixing by the insertion rod 42, the sliding plate 71 will be automatically closed by the elastic action of the return spring 72. The sliding plate 71 is slidably connected to the front surface of the screening and collecting box 5, and the guide rod 73 is fixedly connected to the inner wall of the top of the screening and collecting box 5.
[0036] Working principle: The trapping lamp 2 is located on the right side wall of the housing 1. It emits light of a special wavelength. In the environment where gray planthoppers are active, this special wavelength of light has a strong attraction to gray planthoppers. The gray planthoppers will fly towards the light source and be attracted into the interior of the housing 1, thus starting the capture process. After the gray planthoppers enter the housing 1, the fan 6 works on the left side wall of the housing 1 to generate suction. Since the side walls of the two sets of screening and collection boxes 5 are provided with small through holes, the gray planthoppers will be sucked into the interior of the two sets of screening and collection boxes 5 under the suction of the fan 6. The outer wall of the screening and collection box 5 is in contact with the inner wall of the cavity on the surface of the housing 1, which ensures the effective transmission of suction and the directional movement of gray planthoppers. In this process, gray planthoppers of different sizes or states will be further screened and separated by the slots opened on the side wall of the right screening and collection box 5.
[0037] Simultaneously, after the connecting frame 3, carrying the screening and collection box 5, slides into the appropriate position inside the housing 1, the locking block 9 is rotated. The guide block at the end of the locking block 9 passes through the center of the connecting frame 3 and inserts into the vertical groove penetrating the housing 1, then enters the inner wall of the positioning groove of the rotating block 8. Then, the locking block 9 is rotated in the opposite direction. Because the guide block at the end of the locking block 9 is restricted by the side wall of the housing 1, the locking block 9 will drive the rotating block 8 to rotate synchronously. At this time, the locking block 9 is fixed, thus firmly fixing the connecting frame 3 to the surface of the housing 1, providing stable installation position support for the two sets of screening and collection boxes 5, and ensuring the stability of the entire device during operation. When it is necessary to disassemble a single set of screening and collection boxes 5, such as to clean the collected planthoppers or perform maintenance, the insertion rod 42 is manually pulled outward. The insertion rod 42 slides outward on the inner wall at the top of the connecting frame 3, stretching the limiting spring 41, causing the insertion rod 42 to disengage from the through hole at the top of the connecting frame 3. At this time, the screening and collection box 5 can be removed from the inner wall of the connecting frame 3. The operation is simple and convenient, facilitating the individual processing of the screening and collection box 5.
[0038] When the screening and collecting box 5 is installed on the inner wall of the connecting frame 3 and enters the housing 1 along with the connecting frame 3, the contact block 74 will contact the surface of the housing 1. Due to the obstruction of the surface of the housing 1, the contact block 74 will drive the sliding plate 71 to slide open on the surface of the screening and collecting box 5 along the guide direction of the guide rod 73. At this time, the inlet of the screening and collecting box 5 is in the open state, which makes it convenient for the gray planthoppers sucked in by the fan 6 to enter the screening and collecting box 5 for collection. When the screening and collecting box 5 is disassembled, that is, when the insert rod 42 is released from its fixation, the contact block 74 is no longer restricted by the contact of the surface of the housing 1. Under the elastic restoring force of the return spring 72, the sliding plate 71 will slide in the opposite direction along the guide rod 73, thereby automatically closing the inlet of the screening and collecting box 5, preventing the collected gray planthoppers from escaping, and facilitating the subsequent processing of the screening and collecting box 5, such as transfer and cleaning operations.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
