[0031] In this embodiment, the dilution mechanism includes a rotating tube 11 that is rotatably installed on the upper surface of the horizontal plate 9. The bottom end of the rotating tube 11 is a closed structure. A plurality of first nozzles 12 are evenly and fixedly installed on the outer surface of the rotating tube 11. A rotating joint 19 is installed on the top of the rotating tube 11. Two vertical rods 13 are also fixedly installed on the upper surface of the support platform 1. Support plates 14 are slidably installed on the outer surfaces of the two vertical rods 13. A lifting clamp 15 is fixedly installed between the two support plates 14. A sealing ring 17 is rotatably installed on the outer periphery of the lifting clamp 15. Two conduits 18 are equidistantly and fixedly installed on the outer surface of the sealing ring 17. The end of the conduit 18 away from the sealing ring 17 is connected to the rotating tube 11 through a rotating joint 19.

[0032] When the horizontal plate 9 rotates, the limiting plate 20 drives the conduit 18 to rotate, so that the conduit 18 drives the sealing ring 17 to rotate, so that the pipe mouth of the conduit 18 is connected with the pipe mouth of the liquid inlet pipe 16, so that the external diluent is pumped into the conduit 18 through the liquid inlet pipe 16.

[0033] In this embodiment, a turbine blade 21 is fixedly installed on the inner wall of the rotating tube 11 near its top, and a liquid inlet pipe 16 is fixedly installed through the inner side of the lifting clamp ring 15, and the liquid outlet of the liquid inlet pipe 16 corresponds to the pipe opening of one of the guide tubes 18.

[0034] After the diluent enters the rotating tube 11, the diluent will impact the turbine blades 21 in the rotating tube 11, so that the flowing diluent can drive the rotating tube 11 to rotate through the turbine blades 21, so that the first nozzle 12 installed on the outer surface of the rotating tube 11 can rotate accordingly, so that the sprayed diluent can disperse the contents of the insect intestine more comprehensively.

[0035] In this embodiment, a driving mechanism is installed on the support platform 1, and the driving mechanism includes a door-shaped plate 22 fixedly installed on the upper surface of the support platform 1, and a stepper motor 27 is fixedly installed on the upper surface of the door-shaped plate 22. The output end of the stepper motor 27 passes through the lower surface of the door-shaped plate 22 and is fixedly installed with a first gear 23 and a second gear 24 in sequence. A fourth gear 26 is fixedly installed at the rotation center of the support column 2, and a third gear 25 is fixedly installed at the bottom end of the support tube 3. The first gear 23 is meshed with the third gear 25, and the second gear 24 is meshed with the fourth gear 26. The transmission ratios between the first gear 23, the third gear 25 and the second gear 24, and the fourth gear 26 are oppositely set.

[0036] When in use, the first gear 23 and the second gear 24 are driven to rotate by the stepper motor 27, so that the first gear 23 drives the support tube 3 to rotate 90° through the third gear 25, so that the support tube 3 drives the turntable 4 to rotate 90°; the second gear 24 drives the support column 2 to rotate 180° through the fourth gear 26, so that the door frame 7 installed on the top of the support column 2 drives the electric telescopic rod 8 and the cross plate 9 to rotate 180°.

[0037] In this embodiment, a cleaning mechanism for cleaning the surface of the rotating tube 11 is also installed on the support platform 1, and the cleaning mechanism includes a cover tube 32 inserted through the upper surface of the support platform 1, and a flexible sealing cover 33 is fixedly installed at the tube mouth of the top of the cover tube 32, and the flexible sealing cover 33 can be adaptively adjusted according to the descending height of the cup cover 10; a plurality of second nozzles 37 are evenly fixedly installed on the inner wall of the cover tube 32, and annular tubes 36 that are connected to each other are fixedly installed between the plurality of second nozzles 37, a drainage pipe 39 connected to the interior of the cover tube 32 is fixedly installed through the bottom end of the cover tube 32, and a cleaning pipe 38 connected to the interior of the annular tube 36 is fixedly installed on the outer surface of the support platform 1. A lifting assembly for driving the cover tube 32 to rise and fall is installed on the support platform 1, and the lifting assembly includes a lifting plate 34 fixedly installed on the bottom end of the cover tube 32, and a second rack 35 is fixedly installed on the outer surface of the lifting plate 34, and the top end of the second rack 35 passes through the upper surface of the support platform 1 and is slidably installed therewith, and a mounting plate 30 is fixedly installed on the upper surface of the support platform 1, and a transmission gear 31 is rotatably installed on the outer surface of the mounting plate 30, and a first rack 29 is fixedly installed on the lower surface of a support plate 14 corresponding to the mounting plate 30, and the first rack 29 and the second rack 35 are arranged opposite to each other, and the first rack 29 and the second rack 35 are respectively meshed with the transmission gear 31.

[0038] When the horizontal plate 9 moves up and down, the guide tube 18 can be driven to move synchronously through the limit plate 20, so that the guide tube 18 can drive the first rack 29 to move up and down through the sealing ring 17, the lifting clamp ring 15 and the support plate 14, so that the first rack 29 can drive the second rack 35 to move up and down through the transmission gear 31 meshing therewith, so that the second rack 35 can be driven by the lifting plate 34 to move the cover tube 32 up and down, so that the cover tube 32 can pass through the placement hole 5 on the turntable 4 and be mounted on the corresponding rotating tube 11, so that the external water pump can pump the cleaning liquid into the multiple second nozzles 37 through the cleaning pipe 38 and the annular pipe 36, so that the second nozzle 37 sprays the cleaning liquid to wash the surface of the first nozzle 12 and the rotating tube 11, and the waste liquid generated by the washing is discharged from the drain pipe 39 into the collecting tube for collection; after the cleaning is completed, the lifting assembly can drive the cover tube 32 to be withdrawn from the placement hole 5 so that the turntable 4 can rotate subsequently.

[0039] In this embodiment, an arc-shaped boss 28 is fixedly mounted on the upper surface of the support platform 1 , and both ends of the arc-shaped boss 28 are inclined surfaces.

[0040] After the dilution of the insect intestinal contents is completed, the telescopic end of the electric telescopic rod 8 drives the dilution mechanism to move up and reset through the cross plate 9. After the reset is completed, the driving mechanism continues to drive the turntable 4 to rotate 90°, and the cross plate 9 rotates 180°, so that the diluted beaker 6 rotates toward the arc-shaped boss 28. Since the two ends of the arc-shaped boss 28 are inclined, the arc-shaped boss 28 can exert an upward lifting effect on the bottom of the beaker 6, and lift the beaker 6 up to a certain height, which is convenient for the subsequent taking of the beaker 6.

[0041] In this embodiment, cup covers 10 matching the beaker 6 are fixedly mounted on the lower surfaces of both ends of the horizontal plate 9 , and a limit plate 20 is fixedly mounted on the upper surface of the horizontal plate 9 , and the top end of the limit plate 20 is fixedly mounted on the outer surface of the conduit 18 .

[0042] When the horizontal plate 9 moves downward, the two cup covers 10 will be driven to move downward, so that the two cup covers 10 cover the beaker 6 and the flexible sealing cover 33 respectively, which can prevent the insect intestinal contents in the beaker 6 and the cleaning liquid in the cover tube 32 from splashing out.

[0043] In this embodiment, the filtering mechanism includes a receiving cup 40 , and a filter screen 41 is detachably installed inside the receiving cup 40 near the top thereof.

[0044] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the taken out insect intestinal contents are placed in a clean beaker 6, and the drive mechanism drives the turntable 4 to rotate 90°, and the cross plate 9 to rotate 180°, so that the beaker 6 containing the insect intestinal contents is rotated to the bottom of the clean dilution mechanism. At this time, the telescopic end of the electric telescopic rod 8 pushes the cross plate 9 to move downward, so that the cross plate 9 can drive the rotating tube 11 to insert downward into the beaker 6 containing the insect intestinal contents, and connect the liquid inlet pipe 16 with the external diluent (the external diluent is pumped into the liquid inlet pipe 16 by the pressure pump), so that the external diluent can pass through the liquid inlet pipe 16. , the corresponding conduits 18 and rotary joints 19 enter the rotating tube 11, and then are sprayed out from the multiple first nozzles 12 installed on the outside of the rotating tube 11, so that the sprayed diluent can disperse the insect intestinal contents in the beaker 6, so that the microorganisms and other components in the insect intestinal contents are more uniform, which is convenient for subsequent observation and analysis; after the diluent enters the rotating tube 11, the diluent will impact the turbine blades 21 in the rotating tube 11, so that the flowing diluent can drive the rotating tube 11 to rotate through the turbine blades 21, so that the first nozzles 12 installed on the outer surface of the rotating tube 11 can rotate accordingly, so that the sprayed diluent can disperse the insect intestinal contents more comprehensively;

[0045] After the dilution of the insect intestinal contents is completed, the telescopic end of the electric telescopic rod 8 drives the dilution mechanism to move up and reset through the cross plate 9. After the reset is completed, the driving mechanism continues to drive the turntable 4 to rotate 90°, and the cross plate 9 rotates 180°, so that the beaker 6 with the dilution completed rotates toward the arc-shaped boss 28. Since the two ends of the arc-shaped boss 28 are arranged with inclined surfaces, the arc-shaped boss 28 can exert an upward lifting effect on the bottom of the beaker 6, and lift the beaker 6 up to a certain height, which is convenient for the subsequent taking of the beaker 6; after the cross plate 9 rotates 180°, the used dilution mechanism will rotate to the top of the cover tube 32, so that when the cross plate 9 drives the rotating tube 11 to move downward next time, the second nozzles 37 installed in the cover tube 32 can rinse the rotating tube 11 and the first nozzle 12, so as to avoid the insect intestinal contents adhered to the surface of the used dilution mechanism and the insect intestinal contents in the next beaker 6 from cross-contamination, affecting the accuracy of the subsequent analysis of the insect intestinal contents;

[0046] By taking the beaker 6, pour the diluted insect intestinal contents into the clean receiving cup 40, so that the corresponding clean filter net 41 filters the diluted insect intestinal contents to remove larger particles of the insect intestinal contents, which is convenient for subsequent observation and analysis of the insect intestinal contents.

[0047] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
