DETAILED DESCRIPTION

[0016] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used in the present invention to indicate positions or positional relationships are based on the positions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figure 1-3The cam 3 is a kind of cam 3 that is fixed on the cam 3, and the cam 3 is fixed on the cam 3. The cam 3 is fixed on the cam 3, and the cam 3 is fixed on the cam 3. The cam 3 is fixed on the cam 3, and the cam 3 is fixed on the cam 3. The front end of the adjusting stud 4 extends out of the connecting through-hole 31 and is equipped with a dial handwheel 5, and the rear side of the dial handwheel 5 is abutted against the front side of the adjusting plate 3. Specifically, the dial handwheel 5 includes a shell and a dial installed on the shell. The shell is fixedly connected to the adjusting stud 4, and the rear side of the shell is abutted against the front side of the adjusting plate 3. It should be noted that the dial handwheel 5 is a mature product on the market. Its specific structure and working principle are not described in detail here. By rotating the dial handwheel 5, the adjusting stud 4 can be driven to rotate, thereby adjusting the gap between the fixed plate 2 and the adjusting plate 3. When the shell of the dial handwheel 5 is rotated, the pointer in the dial will rotate, thereby intuitively reflecting the rotation position of the adjusting stud 4. Therefore, according to the reading of the dial handwheel 5, the size of the separation channel 21 (the width of the separation channel 21, that is, the gap between the adjusting plate 3 and the fixed plate 2) can be accurately adjusted, thereby completing the adjustment operation quickly and accurately.

[0019] The working principle of this embodiment is as follows: based on the principle that larvae are smaller than male pupae, and male pupae are smaller than female pupae, when performing separation operation, the size of the separation channel 21 is first adjusted by the dial handwheel 5 located at the upper and lower parts of the adjustment plate 3, so that the size of the lower end of the separation channel 21 is larger than the size of the larvae but smaller than the size of the male; then the culture solution mixed with larvae, male pupae and female pupae is poured into the separation channel 21 from the top of the adjustment plate 3. At this time, the larvae can be discharged from the lower end of the separation channel 21, while male pupae and females cannot pass through the separation channel 21, thereby realizing the separation of the larvae. Since the separation channel 21 gradually narrows from top to bottom, the male pupa will be located below the female pupa. Generally, the adjustment plate 3 is transparent. The material of the separation channel 21 is clear, such as glass, so as to observe the specific separation situation; at this time, the size of the separation channel 21 is adjusted so that the size of the lower end of the separation channel 21 is larger than the size of the male pupa but smaller than the size of the female pupa, and the male pupa is discharged from the lower end of the separation channel 21 (to facilitate its discharge, clean water can be appropriately added to the top of the separation channel 21), thereby realizing the separation of the male pupa; finally, the size of the separation channel 21 is adjusted so that the size of the lower end of the separation channel 21 is larger than the size of the female pupa, so that the female pupa can be collected; in this embodiment, the gap between the fixed plate 2 and the adjustment plate 3 can be adjusted by rotating the dial handwheel 5, and the adjustment can be quickly realized according to the reading of the dial handwheel 5, which is easy to operate and has high separation efficiency.

[0020] Illustratively, a guide plate 32 is provided on the top of the adjustment plate 3, and the guide plate 32 gradually tilts from top to bottom toward the side close to the fixed plate 2. The culture fluid is poured from the top of the guide plate 32, and the culture fluid flows into the separation channel 21 along the guide plate 32, making it easier to pour the culture fluid into the separation channel 21.

[0021] Exemplarily, a guide plate 11 is provided at the bottom of the base plate 1, and the guide plate 11 is located below the adjustment plate 3. The left and right sides of the guide plate 11 are gradually inclined toward the middle from back to front, and a collection port 111 is provided in the middle of the front side of the guide plate 11. After the culture medium is poured into the separation channel 21, the culture medium will flow into the guide plate 11 after passing through the separation channel 21, and then be discharged from the collection port 111 for centralized collection.

[0022] Exemplarily, the left side of the adjustment plate 3 protrudes from the left side of the fixed plate 2, and the right side of the adjustment plate 3 protrudes from the right side of the fixed plate 2. The upper left side, lower left side, upper right side and lower right side of the adjustment plate 3 are respectively provided with connecting holes 31, and each connecting hole 31 is provided with an adjusting stud 4 to ensure that the adjustment plate 3 and the base plate 1 are firmly connected and will not interfere with the separation channel 21.

[0023] Exemplarily, a washer 42 is provided on the adjusting stud 4, and the washer 42 is located between the rear side of the dial handwheel 5 and the front side of the adjusting plate 3, which can prevent the dial handwheel 5 from directly contacting the adjusting plate 3 and causing wear. Generally, the washer 42 is elastic.

[0024] Exemplarily, the length of the bottom plate 1 is 30cm-70cm, the height of the bottom plate 1 is 30cm-60cm, the length of the fixed plate 2 is 20cm-50cm, and the height of the fixed plate 2 is 30cm-50cm. The volume is moderate so that it can be placed in the laboratory, and the single separation efficiency can meet the needs of the experiment.

[0025] Exemplarily, the device also includes a bracket 6, and the left and right sides of the bracket 6 are rotatably connected to the connecting block 12 through the connecting bolt 61, that is, the connecting bolt 61 can be rotatably passed through the connecting block 12 and threadedly connected to the bracket 6. After loosening the connecting bolt 61 (the connecting bolt 61 is not separated from the bracket 6), the connecting block 12 can rotate relative to the bracket 6. After tightening the connecting bolt 61, the connecting block 12 is locked and cannot rotate. The connecting block 12 is fixedly connected to the rear side of the base plate 1, that is, the position of the base plate 1 can be rotated to adjust for observation and operation.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
