[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0021] According to an embodiment of the present invention, a device for raising and collecting midge larvae is provided.

[0022] Example 1;

[0023] like Figures 1-4 As shown, the midge larvae breeding and collection device according to an embodiment of the present invention includes a support base 1, a drain pipe 2 connected to the inner wall of the support base 1, a bearing seat 3 connected to the top of one end of the drain pipe 2, a movable water tank 4 connected to the outer wall of the bearing seat 3, a cylindrical gear ring 6 connected to the top of the movable water tank 4, a fixing rod 7 connected to the top of the support base 1, a support plate 8 connected to the top of the fixing rod 7, a cylinder 9 connected to the top of the support plate 8, a movable plate 10 connected to the bottom of the piston rod of the cylinder 9, and a connecting rod 11 movably connected to the outer wall of the movable plate 10. The bottom of the connecting rod 11 is movably connected to the movable rod 12, and the bottom of the movable rod 12 is movably connected to the movable rack 13. The inner wall of the movable rack 13 is provided with a guide block 14 connected to the top of the support base 1. This facilitates the sliding of the movable rack 13 through the connecting rod 11 and the movable rod 12 when the movable plate 10 descends. This causes the movable rack 13 to drive the cylindrical gear ring 6 to rotate, which in turn causes the cylindrical gear ring 6 to drive the movable water tank 4 to rotate for rinsing. This effectively improves the convenience of rinsing and thus improves the efficiency of collecting midge larvae.

[0024] In this embodiment, the connecting rod 11 and the movable rod 12 are arranged in a "V" shape, and there are two sets of symmetrically distributed connecting rods 11 and movable rods 12. The two sets of connecting rods 11 and movable rods 12 are staggered front and back, which facilitates the connecting rod 11 to drive the movable rod 12 to rotate in the opposite direction when rotating, thereby helping to convert the lifting power into lateral sliding power.

[0025] Furthermore, the inner wall of the movable rack 13 is provided with a through groove, and the movable rack 13 is slidably connected to the guide block 14 through the through groove, which facilitates the guiding work of the movable rack 13 and ensures that the movable rack 13 can perform effective lateral sliding work.

[0026] The movable rack 13 meshes with the cylindrical gear ring 6, and the movable rack 13 and the cylindrical gear ring 6 form a sliding structure, which facilitates the movable rack 13 to drive the cylindrical gear ring 6 to rotate after sliding.

[0027] Regarding how to cut the mud and sand, this embodiment further explains that the inner wall of the movable water tank 4 is connected with cutting protrusions 5. The cutting protrusions 5 are distributed in several groups at equal intervals, and each group of cutting protrusions 5 has several pieces distributed at equal angles. The two connected groups of cutting protrusions 5 are staggered, which makes it convenient for the movable water tank 4 to cut and disperse the mud and sand through the cutting protrusions 5 when it rotates, thereby improving the rinsing effect of midge larvae.

[0028] Based on the above embodiments, this utility model further explains that the bottom of the movable plate 10 is connected to a support rod 15, and the inner wall of the support rod 15 is connected to a clamping block 16 via a spiral spring. One end of the clamping block 16 is connected to an iron ring 17, and the outer wall of the iron ring 17 is connected to a net bag 18. This facilitates the deformation of the spiral spring after the clamping block 16 is rotated, and the iron ring 17 can be effectively clamped after the clamping block 16 is reset and rotated by the elasticity of the spiral spring, thus facilitating the installation of the net bag 18.

[0029] Among them, there are two clamping blocks 16 symmetrically distributed, which effectively improves the stability of clamping and positioning.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical application, firstly, the clamping block 16 is rotated so that the iron ring 17 can drive the net bag 18 to be installed inside the two clamping blocks 16. Then, the cylinder 9 is started, so that the cylinder 9 drives the movable plate 10 to descend, so that the movable plate 10 drives the net bag 18 to fall into the movable water tank 4. When the movable plate 10 descends, it drives the connecting rod 11 to rotate, so that the connecting rod 11 drives the movable rod 12 to rotate in the opposite direction, so that the movable rod 12 drives the movable rack 13 to slide laterally under the guidance of the guide block 14. Thus, the movable rack 13 drives the cylindrical gear ring 6 to rotate, so that the cylindrical gear ring 6 drives the movable water tank 4 to rotate, and then the midge larvae in the net bag 18 are rinsed and collected.

[0032] In summary, by utilizing the above-mentioned technical solution of this utility model, the convenience and efficiency of rinsing are effectively improved through automatic rinsing.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
