Description
Technical Field
[0001] The utility model relates to the technical field of black soldier fly breeding, in particular to a fresh worm fine classifier for black soldier flies. Background Art
[0002] The black soldier fly, a saprophagous insect of the family Stratiomyidae, can feed on livestock and poultry manure and domestic garbage, and produce high-value animal protein feed. Due to its rapid reproduction, large biomass, wide food habits, high absorption and conversion rate, easy management, low feeding cost, good animal palatability and other characteristics, it is resourcefully utilized and is currently widely used in the treatment of waste such as chicken manure, pig manure and kitchen waste.
[0003] After the black soldier flies are bred, they need to be screened out from the manure and then finely divided. Most of the existing fresh worm fine classifiers use vibrating screens to achieve the fine division function. The vibrating screen and the frame are usually rigidly connected. Therefore, during the use of the vibrating screen, the entire frame will vibrate accordingly, resulting in the very easy breakage of the connecting components between the frame and the vibrating screen, and the high equipment maintenance cost.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] like Figures 1 to 3 As shown, the utility model provides a fresh insect segmenting machine for black soldier flies, comprising an upper frame 1 and a lower frame 2 which are distributed in an upper and lower manner, the upper frame 1 is equipped with a drum screen 3, the drum screen 3 can preliminarily screen out the black soldier flies from feces, a mounting bracket 4 is arranged in the lower frame 2, a reciprocating screen 5 is installed in the mounting bracket 4, the reciprocating screen 5 can segment the black soldier flies, a plurality of first mounting seats 21 are arranged at intervals on both sides of the top of the lower frame 2, a plurality of second mounting seats 41 are arranged at positions corresponding to the first mounting seats 21 on both sides of the bottom of the mounting bracket 4, the first mounting seats 21 and the second mounting seats 41 are softly connected by a steel rope 6, when the reciprocating screen 5 is started, the reciprocating screen 5 will swing back and forth in the mounting bracket 4, thereby playing a screening role, in this process, the force generated by the reciprocating screen 5 on the lower frame 2 will be offset by the continuous swing of the steel rope 6, so that the lower frame 2 will not vibrate along with the reciprocating screen 5, thereby ensuring the stability of the lower frame 2 and improving the service life of the equipment.
[0031] Specifically, in the present embodiment, rotating wheels 11 are movably provided around the bottom of the upper frame 1, and the rotating wheels 11 are transmission connected to the bottom of the drum screen 3. One of the rotating wheels 11 is transmission connected to the first driving motor 12. When the first driving motor 12 is started, the rotating wheel 11 will drive the drum screen 3 to rotate. Since a number of primary screening holes are evenly arranged on the drum screen 3, the black soldier flies will gradually drill into the primary screening holes of the drum screen 3 in the feces, and then fall onto the reciprocating screen 5.
[0032] As shown Figure 5 in the figure, to prevent the initial screening holes of the drum sieve 3 from being blocked, at both ends of the top of the upper frame 1 of this embodiment, fourth mounting seats 15 are installed. A first rotating shaft 13 is movably connected between the two fourth mounting seats 15. The first rotating shaft 13 is located inside the drum sieve 3, and a number of brush hairs 14 are distributed at intervals on the first rotating shaft 13. The brush hairs 14 are in contact with the inner wall of the drum sieve 3. The first rotating shaft 13 is drivingly connected to a third driving motor 16. When the third driving motor 16 is started, the first rotating shaft 13 will drive the brush hairs 14 to rotate to clean the initial screening holes of the drum sieve 3, avoiding the initial screening holes being blocked by feces and preventing the black soldier flies from drilling out.
[0033] Since the drum sieve 3 is in a rotating state during the preliminary screening process, the materials inside the drum sieve 3 may fly out of the drum sieve 3 through the initial screening holes. Therefore, on both sides of the upper frame 1 where the drum sieve 3 is located in this embodiment, baffle plates 7 are provided. The materials that fall during the rotation of the drum sieve 3 will be blocked by the baffle plates 7, and the baffle plates 7 are inclined downward, so that the lower ends of the baffle plates 7 are located above the reciprocating sieve 5. Under the guiding action of the baffle plates 7, the materials will enter the reciprocating sieve 5.
[0034] Preferably, the drum sieve 3 of this embodiment is inclined downward. At the lower end of the upper frame 1 where the drum sieve 3 is located, a feed hopper (not shown in the figure) is provided. After preliminary screening, the black soldier flies will enter the reciprocating sieve 5 through the initial screening holes of the drum sieve 3, while the remaining feces will enter the feed hopper along the inclined direction of the drum sieve 3 for collection.
[0035] As shown Figure 4 in the figure, on both sides of the top of the mounting bracket 4 of this embodiment, a number of third mounting seats 42 are provided at intervals. The third mounting seats 42 are all hinged with first connecting rods 43, and the other ends of the first connecting rods 43 are all hinged with the side surface of the reciprocating sieve 5, so as to position the reciprocating sieve 5. At the same time, one end of the mounting bracket 4 is movably provided with a second rotating shaft 44. The second rotating shaft 44 is drivingly connected to a second driving motor 45, and eccentric wheels 46 are connected to both ends of the second rotating shaft 44. The eccentric wheels 46 are drivingly connected to a second connecting rod 47, and the other end of the second connecting rod 47 is hinged with one end of the reciprocating sieve 5. When the second driving motor 45 is started, the second rotating shaft 44 will drive the eccentric wheels 46 to rotate, and the eccentric wheels 46 drive the second connecting rod 47 to perform an eccentric motion, so that the reciprocating sieve 5 can shake back and forth, thus playing a role in screening.
[0036] More specifically, the reciprocating sieve 5 includes a number of sub-sieves arranged vertically. In this embodiment, it is preferably three layers of sub-sieves. The sub-sieves are arranged in a downward slope, and a number of sub-sieve holes are evenly arranged on the sub-sieves. The aperture of the sub-sieve holes becomes smaller from top to bottom in sequence, so as to be able to subdivide the size of the black soldier fly. At the same time, a material receiving plate is also arranged below the bottommost sub-sieve for receiving the smallest black soldier flies.
[0037] It should be noted that the above specific implementation manners are only the preferred embodiments of the present utility model and the technical principles applied. Those skilled in the art should understand that various modifications, equivalent replacements, changes, etc. can also be made to the present utility model. However, as long as these transformations do not deviate from the spirit of the present utility model, they should be within the protection scope of the present utility model. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
