[0010] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] A drive motor rotates the rearing cylinder at a uniform speed, separating the mature larvae from their food residue. A double-layered screen waste collection box is located below the base, where adult larvae and insect waste are automatically graded and screened through a sorting port. This invention enables coordinated sorting, significantly reducing manual intervention costs and improving sorting accuracy, making it suitable for large-scale automated sorting scenarios.

Detailed Implementation

[0017] The specific embodiments of the present invention will now be described in full with reference to the accompanying drawings. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details are not intended to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some known and conventional structures and components will be shown in the drawings in a simple schematic manner.

[0018] like Figure 1-4As shown, this utility model discloses an automatic sorting device for black soldier fly larvae, comprising an outer cover 4, a rearing cylinder 1, a base 3, and a drive motor 2. The outer cover 4 is fixed to the base 3 by bolts. The rearing cylinder 1 is movably located inside the outer cover 4. The rearing cylinder 1 includes: a cylinder end cap 102, a spiral blade 104, and a rearing cylinder body 101. The spiral blade 104 is fixedly connected to the inner surface of the rearing cylinder body 101. Screening holes with a diameter of 5 mm are evenly opened on the side wall of the rearing cylinder body 101. The cylinder end cap 102 is connected to the end face of the rearing cylinder body 101 by a hinge. The output end of the drive motor 2 is connected to a rotating wheel 6 via a belt 7. The rotating wheel 6 is fixedly connected to the other end face of the rearing cylinder body 101. The base 3 is fixedly connected to the outer shell of the drive motor 2.

[0019] Furthermore, the upper end of the base 3 is fixedly connected to a cylindrical support frame 9, and there are four cylindrical support frames 9. The aquaculture cylinder 101 is slidably located at the upper end of the cylindrical support frame 9.

[0020] Furthermore, each of the cylindrical support frames 9 includes: a support body 901 and a bearing 902. The upper end of the base 3 is fixedly connected to the support body 901, and the support body 901 is fixedly connected to the inner ring of the bearing 902. The outer wall edge of the aquaculture cylinder 101 is provided with a guide groove 103, and the guide groove 103 is engaged with the outer ring of the bearing 902.

[0021] Furthermore, the depth of the guide groove 103 is 3mm-5mm, and a flexible rubber strip is embedded in the guide groove 103.

[0022] Furthermore, the device also includes: a waste collection box 10, which is slidably connected to the base 3. The waste collection box 10 is located directly below the aquaculture cylinder 101. The base 3 has an opening located directly above the waste collection box 10, which facilitates the falling of sand or feed from the screening holes.

[0023] Furthermore, the waste collection box 10 is equipped with a double-layer screen, with the upper screen having an aperture of 3mm and the lower screen having an aperture of 0.5mm. This allows adult insects that are mistakenly screened out of the breeding cylinder 101 to be trapped by the upper screen, while the insect debris falls into the lower layer for collection, achieving secondary screening and reducing manual intervention.

[0024] Furthermore, the lower four feet of the base 3 are each fixedly connected to the fixed end of a caster wheel 8. The caster wheel 8 is equipped with a self-locking function, and the surface of the wheel is covered with an anti-slip silicone layer.

[0025] Example: The rotation of the cylinder mixes the black soldier fly larvae and feed, optimizing the uniformity of the rearing process. The cylinder end cap 102 is connected to the rearing cylinder 101 via a hinge, facilitating the opening and closing of the rearing cylinder 101 and allowing the mixture of black soldier fly larvae, food residue, and rearing sand to be screened to be placed into the rearing cylinder 1. Circular screening holes with a diameter of 5mm are evenly distributed on the side wall of the rearing cylinder 101 to facilitate the separation of larvae from food residue and sand during the screening process. The waste collection box 10 can be a pull-out design to collect the screened sand and feed for centralized processing. By energizing and simply controlling the drive motor 2, the drive motor 2 drives the rearing cylinder 101 to rotate via the belt 7. The spiral blades 104 then break up the mixture of black soldier fly larvae and food residue, achieving efficient separation of larvae and food residue waste. Waste is sieved out of the screening holes of the breeding cylinder 101 by gravity and the action of the spiral blades 104, and enters the waste collection box 10. Adult insects that are mistakenly sieved out of the breeding cylinder 101 are intercepted by the upper screen, while the insect sand falls into the lower collection layer, achieving secondary screening and reducing manual intervention. Subsequently, the adult insects retained in the breeding cylinder 101 are removed by opening the cylinder end cap 102 and processed for the next step. This automates the sorting process.

[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
