[0002] The striped stem borer is an insect of the genus C. graminaceae of the order Lepidoptera, also known as heart borer, stalk borer, and dead heart borer. It is a common pest, and the drilling column of its larvae can cause serious damage to rice. Leading to rice yield reduction. In order to study better killing methods, clarifying the division of its larval ages is an important technical basis for accurate prediction and scientific prevention and control of the striped stem borer. Then, striped stem borer larvae and prepupae of different ages are needed for experiments. At present, the more mature basis for dividing its ages is that the width of the head shell of the striped stem borer larvae will show significant differences with each molting. Therefore, the width of the head shell is used as an age index for the striped stem borer larvae. However, if manual measurement is used for screening and separation, the efficiency is too low. Therefore, a device that can efficiently separate striped stem borer larvae and prepupae of different ages is needed. Utility Model Content

[0015] Beneficial effects of the utility model

[0016] 1. After the first screening and collection of the smallest headshell of the Chilo suppressalis larvae and prepupae, the other Chilo suppressalis larvae and prepupae are screened again, among which there may be Chilo suppressalis larvae and prepupae with the smallest headshell that can pass through the first screening but cannot enter the through hole with the smallest aperture. At this time, if the Chilo suppressalis larvae want to pass through the through hole with the second smallest aperture, the laser sensors on both sides of the upper end of the through hole with the second smallest aperture cannot detect that it has passed through, but the laser sensors at both ends of the middle can detect that it has passed through.

[0032] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0033] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "linked to" another element, it can be directly linked to the other element or indirectly linked to the other element.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] In one embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a rice stem borer larvae and prepupae efficient separation device, comprising a bottom plate 100, an annular baffle 200, a separation barrier 300 and a rotating disk 400;

[0037] The annular baffle 200 is fixedly arranged at the middle part of the upper end of the bottom plate 100; the separation barrier 300 is an annular structure; the separation barrier 300 is arranged on the annular baffle 200; the turntable 400 is arranged at the upper end of the inner circle of the annular baffle 200, and a driving motor 401 is connected to the lower end of the turntable 400.

[0038] A plurality of through holes 301 are formed through the bottom of the separation barrier 300 from the inside to the outside, and the diameters of the plurality of through holes 301 increase sequentially.

[0039] It is understandable that when the utility model is used, the larvae and prepupae of the striped stem borer are placed on the rotating disk 400, and the larvae and prepupae on the rotating disk 400 are encircled by the annular separation barrier 300. The larvae and prepupae of the striped stem borer can only pass through the through holes 301 set on the separation barrier 300, and the diameters of the plurality of through holes 301 are inconsistent. In the first screening, the larvae and prepupae that can pass through the through holes 301 with the smallest aperture can be screened out and then collected. Since the smaller larvae and prepupae may pass through the through holes 301 with larger apertures, the larvae and prepupae that pass through the other through holes 301 need to be poured into the rotating disk 400 again for screening. After multiple screenings, when there are fewer larvae and prepupae left on the rotating disk 400, they can be screened manually. The utility model is easy to operate and can well separate the larvae and prepupae of the chilo suppressalis of different ages.

[0040] In another embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides an efficient separation device for rice stem borer larvae and prepupae, wherein a plurality of partitions 101 are provided on the bottom plate 100, one end of the plurality of partitions 101 is fixedly connected to the annular baffle 200, and the plurality of partitions 101 separate the bottom plate 100 into a plurality of placement areas 102.

[0041] Furthermore, a drawable placement box 103 is respectively provided in each of the plurality of placement areas 102 ; and the positions of the plurality of through holes 301 correspond to the positions of the plurality of placement areas 102 .

[0042] It can be understood that the plurality of placement boxes 103 are used to collect the larvae and prepupae of Chilo suppressalis passing through the holes 301 from corresponding positions, and the structure is simple and practical.

[0043] In yet another embodiment, as shown in FIG. Figure 4 , Figure 6 As shown, the utility model provides a high-efficiency separation device for rice stem borer larvae and prepupae, the bottom plate 100 and the annular baffle 200 form a cavity 201, the driving motor 401 is arranged in the cavity 201; the main shaft of the driving motor 401 is connected to a driving wheel 402; the bottom of the turntable 400 is provided with a rotating shaft 403, and the rotating shaft 403 is connected to a driven wheel 404 meshing with the driving wheel 402.

[0044] It is understandable that in order to prevent larger larvae and prepupae from accumulating in the smaller apertures 301 that cannot pass through, thereby affecting the passage of other larvae and prepupae, the drive motor 401 is used to rotate the turntable 400 to change its position.

[0045] In yet another embodiment, Figure 5 As shown, the utility model provides an efficient separation device for rice stem borer larvae and prepupae, wherein the separation barrier 300 is internally provided with laser sensors 302 and alarms 303 corresponding to the plurality of through holes 301; the laser sensors 302 are in two pairs, one pair is arranged at both sides of the upper ends of the corresponding through holes 301, and the other pair is arranged at both sides of the middle of the corresponding through holes 301, and the alarms 303 are electrically connected to the corresponding two pairs of laser sensors 302, respectively.

[0046] It should be understood that in order to avoid the screening errors caused by the smaller larvae and prepupae passing through the through hole 301 larger than their own aperture, two pairs of laser sensors 302 and an alarm 303 electrically connected thereto are provided. Specifically, after the first screening collects the larvae and prepupae with the smallest head shell, the other larvae and prepupae are screened again, among which there may be larvae and prepupae with the smallest head shell that can pass through but fail to enter the through hole 301 with the smallest aperture in the first screening. At this time, if the larvae want to pass through the through hole 301 with the second smallest aperture, the laser sensors 302 located at both sides of the upper end of the through hole 301 with the second smallest aperture cannot detect that it has passed, but the laser sensors 302 at both ends of the middle can detect that it has passed, and at this time the alarm 303 sounds an alarm, and the staff can manually separate the larvae. Through this screening mode, until all the larvae and prepupae that can pass through the through hole 301 with the largest aperture are screened, it is sufficient.

[0047] In the last embodiment, if Figure 7 As shown, the utility model provides a highly efficient separation device for rice stem borer larvae and prepupae, wherein the separation barrier 300 is further provided with a first cover plate 304 , and a second cover plate 104 is provided above the plurality of partitions 101 .

[0048] It is understandable that the first cover plate 304 is used to prevent the larvae and prepupae of the striped stem borer in the rotating disk 400 from crawling out through the separation barrier 300. The second cover plate 104 can be covered after the screening is completed, and is also used to prevent the larvae and prepupae of the striped stem borer in the placement box 103 from crawling out.

[0049] It should be noted that the plurality of placement boxes 103 may contain food for inducing larvae and prepupae of Chilo suppressalis, such as rice stalks.

[0050] It should also be added that labels 105 are attached to the outer sides of the plurality of placement boxes 103 to distinguish between Chilo suppressalis larvae and prepupae of different head shell sizes.

[0051] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0052] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only a preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection scope of the utility model.
