[0043] At present, when preparing bait for black soldier flies, the food waste is manually screened and directly transported to the pulping equipment through a screw conveyor to be mixed with the pre-made slurry for stirring, and then put into a culture bag for culturing black soldier flies. Due to the manual screening, the efficiency is low and the screening effect is poor. The food waste entering the pulping equipment for stirring is easy to cause the machine to jam, the machine failure rate is high, and the cost of preparing black soldier fly bait is high.

[0044] In view of this, the designers designed a black soldier fly bait preparation system with a high degree of automation and high preparation efficiency; the food waste is well crushed and is not prone to jamming, which reduces the failure rate and preparation costs.

[0045] See also Figure 1 In this embodiment, the black soldier fly bait preparation system includes a first-stage crushing device 100, a second-stage crushing device 200, an oil-water separator 300, a pulping device 400 and a packaging device 500. The first-stage crushing device 100 is used to crush food waste to obtain primary raw materials. The second-stage crushing device 200 is connected to the first-stage crushing device 100, and is used to receive and crush the primary raw materials to obtain secondary raw materials. The oil-water separator 300 is connected to the liquid outlet of the second-stage crushing device 200, and is used to receive the secondary raw materials and separate the secondary raw materials into residues and grease. The pulping device 400 is connected to the residue outlet of the oil-water separator 300, and is used to mix the pre-made slurry and the residue to obtain organic slurry. The subpackaging device 500 includes a silo 510 and a subpackaging mechanism 520. The silo 510 is connected to the pulping device 400 and is used to stir the organic slurry and distribute the organic slurry to the subpackaging mechanism 520 for breeding black soldier flies.

[0046] The operation process of the black soldier fly bait preparation system provided in this embodiment includes, for example:

[0047] After the kitchen waste is collected, it is first crushed by the first-stage crushing device 100 to obtain the primary raw material. The particle size of the primary raw material is smaller than that of the kitchen waste. Then, the primary raw material is transported to the second-stage crushing device 200 for the second crushing. In this way, the primary raw material can be crushed into a secondary raw material with a smaller particle size, and after two crushings, the kitchen waste that is difficult to crush and difficult to crush is basically crushed, and the subsequent jamming of the machine is not easy. Then, the secondary raw material is transported to the oil-water separator 300, the secondary raw material is separated, and the residue and grease in the secondary raw material are separated. The grease can be collected and used or sold. The residue is transported to the pulping device 400, and the residue is mixed with the prefabricated slurry to obtain an organic slurry. Finally, the organic slurry is transported to the subpackaging device 500, and the subpackaging device 500 can stir and mix the organic slurry again, and then distribute it to the subpackaging mechanism 520 as needed. The organic slurry on the subpackaging mechanism 520 is the black soldier fly bait, which can be directly used for the breeding of black soldier flies. The preparation process of black soldier fly bait has a high degree of automation, high operating efficiency and low manufacturing cost. In addition, it is not easy to get stuck, the failure rate is reduced, and the kitchen waste can be maximized to improve the utilization rate of resources.

The lifting unit 610 is used to drive the collection bucket 620 to rise and fall, and then after the collection bucket 620 is lifted to a set height, the collection bucket 620 is dumped. During the dumping of the collection bucket 620, the food waste in the collection bucket 620 enters the first-stage crushing device 100 from the bucket mouth.

[0049] Please combine Figure 2 and Figure 3 Optionally, the lifting unit 610 includes a frame 611, a driving unit 612, a base plate 613, a bearing plate 614 and a telescopic unit 615. The frame 611 is a metal frame, and the frame 611 is welded and fixed to the first-stage crushing device 100. For example, the frame 611 is a rectangular frame, and the frame 611 is vertically arranged. The collecting bucket 620 and the frame 611 are slidably matched in the height direction of the frame 611, so that the collecting bucket 620 is lifted and lowered along the height direction of the frame 611. Furthermore, the frame 611 is also provided with a guide groove 6111, and the groove bottom wall 6112 of the guide groove 6111 is an inclined surface, so that the groove depth of the guide groove 6111 gradually becomes shallower in the bottom-up direction, that is, when the frame 611 is assembled with the first-stage crushing device 100, the notch of the guide groove 6111 faces the first-stage crushing device 100, and at this time, the distance between the groove bottom wall 6112 of the guide groove 6111 and the first-stage crushing device 100 gradually decreases in the bottom-up direction. The driving unit 612 can be a chain transmission unit, and the driving unit 612 is arranged on the frame 611. The base plate 613 is connected to the chain, and the base plate 613 and the frame 611 are slidably matched, and the base plate 613 is guided to slide stably through the frame 611. After the driving unit 612 is started, it can drive the base plate 613 to rise and fall relative to the frame 611.

The transmission rod 650 is inserted into the guide groove 6111, and one end face of the transmission rod 650 is in contact with the bottom wall 6112 of the guide groove 6111. When the driving unit 612 is used to move the collecting barrel 620 from bottom to top, under the cooperation of the transmission rod 650 and the guide groove 6111, the collecting barrel 620 gradually moves away from the frame 611, that is, the collecting barrel 620 gradually approaches the first-stage crushing device 100, so that the collecting barrel 620 guides the flow during the lifting process. The plate 640 is not easy to collide with the first-stage crushing device 100. After the collection barrel 620 rises to the set height, the distance between the collection barrel 620 and the first-stage crushing device 100 is reduced, and the guide plate 640 can pass over the top of the first-stage crushing device 100 and be located in the area surrounded by the feed port of the first-stage crushing device 100. When the collection barrel 620 is rotated and tilted by the telescopic unit 615, the guide plate 640 is always located in the area surrounded by the feed port of the first-stage crushing device 100, and it is not easy to cause material leakage. The end of the elastic member 630 away from the collection barrel 620 is supported on the base plate 613, so that the collection barrel 620 always has a tendency to approach the frame 611. When the collection barrel 620 descends, under the action of the elastic member 630, the collection barrel 620 gradually moves away from the first-stage crushing device 100. The guide plate 640 will not scratch or collide with the first-stage crushing device 100, and the safety is high.

[0051] It should be understood that the elastic member 630 may be, but is not limited to, a spring.

The pump body 514 is connected to the body 511, and is used to distribute the stirred organic slurry to the subpackaging mechanism 520. When the slurry mixed and stirred by the pulping device 400 enters the body 511, the stirring shaft 512 rotates under the drive of the motor, driving the stirring blade 513 to rotate. Since the stirring blade 513 is inclined, the mixture is driven to rotate and rise and fall during the stirring of the mixture, and the mixing effect is good, and the homogenization of the black soldier fly bait is further realized, which is beneficial to the breeding of black soldier flies. Meanwhile, the stirring blade 513 has a blade, which can break the impurities attached to the stirring blade 513 in real time, avoiding the accumulation of impurities and causing the machine to jam, and the operation is more stable and reliable.
