Description

Technical Field

[0001] The present invention belongs to the technical field of culturing fly maggots with kitchen waste, and specifically refers to a multi-layer fly maggot breeding device for kitchen waste. Background Art

[0002] Fly maggots are high-quality animal protein feeds. Fly maggot feeds have good palatability, high conversion rates, and rich nutrition. It has been experimentally proven that using fly maggots to replace part or all of the fish meal as feed for feeding livestock, poultry, fish, etc. has achieved good breeding effects. Artificial breeding of fly maggots does not require much equipment and can be carried out indoors and outdoors, in cities and rural areas. Currently, a large amount of kitchen waste is produced, and using kitchen waste to raise fly maggots can not only reduce the amount of kitchen waste but also reduce feed costs.

[0003] Kitchen waste includes leftovers, rice, vegetable leaves, fruit peels, bones, etc. Therefore, kitchen waste contains extremely high moisture and organic matter. However, the feed for fly maggot breeding should not have too high moisture content. It needs to be crushed and dewatered before being used to breed fly maggots. And in order to improve the practicability of using kitchen waste to raise fly maggots, a device that can automatically layer and raise fly maggots is proposed. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a multi-layer fly maggot breeding device for kitchen waste. The kitchen waste is crushed into fine particles by a crushing blade, and the water therein is separated out to form a viscous fluid. Then, through the reciprocating movement of the piston device in the dehydration tank, the kitchen waste fluid is put into the dehydration tank, and through the extrusion of the piston plate and the dehydration plate, the water therein is discharged from the drain pipe. After fermentation in the fermentation tank, it forms a fly maggot culture; two piston plates are connected by a piston spring, and one piston plate pushes the other piston plate to complete the extrusion of the kitchen waste fluid. The piston spring plays a buffering role to prevent the piston plate from being overstressed; the conveying rack transports the culture box containing fly maggot larvae, and the culture is discharged into the culture box through the discharge plate. The telescopic handling component will place the culture box on the layered culture device. The handling plate of the telescopic handling device will extend when it is under pressure and retract after the pressure is eliminated. At the same time, when the lower layered plate has a culture box placed on it, the upper layered plate will emerge from the layered device slot, thereby achieving the technical effect of layering and placing the culture box to raise fly maggots, effectively solving the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a multi-layer fly maggot breeding device for kitchen waste, including a crushing device, a dehydration and fermentation device, a conveyor rack, a telescopic handling component, and a layered cultivation device. The crushing device is arranged on the dehydration and fermentation device, the conveyor rack is arranged in front of the dehydration and fermentation device, the layered cultivation device is arranged in front of the telescopic handling component, and the conveyor rack is arranged on the side of the telescopic handling component. The crushing device includes a crushing box, a crushing motor, a crushing shaft, a turntable, and crushing blades. The crushing motor is arranged on the crushing box, the crushing shaft is arranged on the crushing motor, the crushing shaft rotates inside the crushing box, the crushing blades are arranged on the crushing shaft, the crushing blades rotate inside the crushing box, the turntable is arranged at the bottom of the crushing shaft, the turntable is arranged at the bottom outside the crushing box, the crushing box is provided with a feeding port and a discharging port, and the turntable is provided with a turntable drive shaft.

[0006] Preferably, the kitchen waste is put into the crushing box through the feeding port, and the crushing blades crush the kitchen waste, during which water is separated out, and at the same time the kitchen waste is crushed into fine particles, forming a viscous fluid.

[0007] Furthermore, the dehydration and fermentation device includes a dehydration tank, a one-way valve, a piston device, a piston drive device, and a fermentation tank. The dehydration tank is provided with a feeding pipe, a dehydration plate, a drain pipe, a discharging pipe, and a piston rod groove. The feeding pipe is connected to the discharging port, the one-way valve is arranged inside the feeding pipe, the piston device slides inside the dehydration tank, the piston drive device is arranged at the bottom of the crushing box, the fermentation tank is arranged below the dehydration tank, the fermentation tank is provided with an exhaust hole, a discharging pipe, a fermentation motor, a support frame, and a discharging plate. The discharging pipe is connected to the fermentation tank, the fermentation motor is arranged on the discharging pipe, and the discharging plate is arranged on the discharging pipe.

[0008] Preferably, when the piston device reciprocates inside the dehydration tank, it will cause alternating negative pressures on both sides, enabling the one-way valves on both sides to alternately put the crushed kitchen waste fluid into the dehydration tank and be compressed by the piston device. At the same time, the closing plate one and the closing plate two move along to close the discharging pipes on their sides, thereby squeezing out the water in the kitchen waste fluid through the dehydration plate, and the squeezed-out water is discharged from the drain pipe. The dehydrated substance is more viscous and has a slower falling rate. When the next fluid to be dehydrated enters the dehydration tank, the previous fluid has not completely been discharged from the discharging pipe of the dehydration tank, achieving the technical effect of cyclic dehydration of the kitchen waste fluid.

[0009] Furthermore, the piston device is provided with a first piston plate, a first piston rod, a second piston plate, a second piston rod and a piston spring. The piston spring is arranged between the first piston plate and the second piston plate. The first piston rod is arranged on the first piston plate. The second piston rod is arranged on the second piston plate. The first piston rod is provided with a first clamping groove. The second piston rod is provided with a second clamping groove. The second piston rod slides on the first clamping groove. The first piston rod slides on the second clamping groove. The first piston plate is provided with a first closing plate. The second piston plate is provided with a second closing plate.

[0010] Furthermore, the piston driving device includes a sliding groove frame, a sliding rod, a sliding shell, a first piston driving rod and a second piston driving rod. The sliding rod is provided with a sliding rod groove and a sliding connecting rod. The sliding groove frame is arranged on the crushing box. The sliding rod slides on the sliding groove frame. The turntable driving shaft slides in the sliding rod groove. The sliding shell is arranged on the sliding connecting rod. The first piston driving rod slides in the sliding shell. The second piston driving rod slides in the sliding shell. The first piston driving rod is arranged on the first piston rod. The second piston driving rod is arranged on the second piston rod.

[0011] Preferably, the rotation of the turntable causes the turntable driving shaft to drive the sliding rod to make a reciprocating motion in the sliding groove frame, thereby driving the sliding shell to move. When the sliding shell moves to the left, the inner wall on the right side of the sliding shell will push the first piston driving rod to move to the left. When the sliding shell moves to the right, the inner wall on the left side of the sliding shell will push the second piston driving rod to move to the right, thereby driving the first piston plate and the second piston plate to make a reciprocating motion in the dehydration tank. And there is a piston spring between the first piston plate and the second piston plate. During the process that the first piston driving rod drives the first piston plate to move to the left, it is the elastic force provided by the piston spring that pushes the second piston plate to move to the left. During the process that the second piston plate compresses the flowable substance of the crushed food waste, due to too much flowable substance, the compressed volume is large, or the moisture content of the flowable substance itself is too low to be compressed, the piston spring starts to play a buffering role to prevent the second piston plate from being overloaded. The same is true when moving to the right.

[0012] Furthermore, the conveying rack includes a conveying rack fixing rod, a transmission rack side plate, a transmission rod, a conveying rack motor and a support plate. The transmission rack side plate is arranged on the conveying rack fixing rod. The conveying rack motor is arranged on the transmission rack side plate. The conveying rack motor drives the transmission rod to rotate through a transmission chain. The transmission rod rotates on the transmission rack side plate. The support plate is arranged on the transmission rack side plate. The support plate is provided with a support rod, a rotating part, a rotating shaft and an elastic part. The rotating shaft rotates on the transmission rack side plate.

[0013] Preferably, there is a suspension at the tail of the conveying rack. The support plate prevents the incubator from falling off the conveying rack during the movement process, and when the telescopic handling device lifts the incubator from the suspension, the support plate can be rotated to prevent the support plate from blocking the movement of the handling fixing plate.

[0014] Furthermore, the telescopic handling assembly includes a fixed plate, a driving device, and a telescopic handling device. The driving device is disposed on the fixed plate, and the telescopic handling device is disposed on the driving device. The fixed plate is provided with a stabilizing frame, a transmission belt rotating groove, a central frame, and a motor fixing frame.

[0015] Furthermore, the driving device is provided with a handling motor, a transmission wheel gear member, a transmission wheel, and a handling conveyor belt. The handling motor is disposed on the motor fixing frame. The transmission wheel gear member rotates on the fixed plate. The transmission wheel rotates on the fixed plate. The handling motor is provided with a motor shaft and a motor gear. The transmission wheel gear member is provided with a transmission gear and a driving transmission wheel. The motor gear is disposed on the motor shaft. The motor gear is meshed and connected with the transmission gear. There are three transmission wheels which are respectively disposed at three corners of the transmission belt rotating groove. The driving transmission wheel is disposed at the fourth corner of the transmission belt rotating groove. The driving transmission wheel is connected with the transmission wheels through a transmission belt. The handling conveyor belt is disposed on the transmission wheels and the driving transmission wheel. The handling conveyor belt is provided with a rotating shaft sleeve.

[0016] Furthermore, the telescopic handling device is provided with a handling plate, telescopic connecting rods, a lifting plate, and a handling fixing plate. The handling plate is provided with sliding wheels, handling plate telescopic rods, and a telescopic plate. The lifting plate is provided with a fixed shaft sleeve and a lifting plate sliding groove. The handling fixing plate is provided with a positioning rod, a positioning base, a handling spring, and a center of gravity rotating shaft. There are four handling plate telescopic rods. The telescopic plate is disposed on the middle two handling plate telescopic rods. The handling plate telescopic rods slide in the fixed shaft sleeves. One end of the telescopic connecting rod rotates on the telescopic plate. The other end of the telescopic connecting rod rotates on the handling fixing plate. The lifting plate sliding groove slides on the handling fixing plate. The lifting plate slides on the positioning rod. The handling spring is disposed on the positioning rod. The handling spring is disposed between the positioning base and the lifting plate.

[0017] Preferably, the center of gravity rotating shaft of the handling fixing plate rotates in the rotating shaft sleeve of the handling conveyor belt and is driven to rotate by the handling conveyor belt. Under its own gravity, the telescopic handling device keeps the handling fixing plate in a vertical state all the time. The handling spring makes the lifting plate at the top. When the handling plate touches the incubator, the gravity of the incubator will press down the handling plate. At the same time, the telescopic connecting rod will push out the handling plate. The handling plate extends to the center of the incubator and lifts the incubator. During the process, the sliding wheels prevent the handling plate from pushing out the incubator, and the sliding wheels will lock after being fully stressed to prevent them from rolling.

[0018] Furthermore, the layered culture device is provided with a culture rack, a layered plate, a layered rod, and a culture box. The culture rack is provided with a culture rack side plate, a stable cross bar, and a support device. The culture rack side plate is provided with a layered device groove. The stable cross bar is provided on the culture rack side plate. The culture rack side plate is provided on the support device. The layered plates are arranged in an array in the layered device groove. The layered rod is arranged between adjacent layered plates. The edge of the culture box is arranged on the layered plate.

[0019] Furthermore, the layered plate is provided with a counterweight, a layered plate rotating shaft, and a layered plate rotating rod. The counterweight is arranged on the outer side of the layered plate. The layered rod is provided with a layered rod sliding groove and a layered rod rotating hole. The layered rod sliding groove is arranged on the layered plate rotating rod of the upper layered plate of two adjacent layered plates. The layered plate rotating rod of the lower layered plate rotates in the layered rod rotating hole.

[0020] Preferably, when the culture box is not placed on the culture rack, the lowermost layered plate protrudes and is exposed outside the layered device groove. Under the action of the counterweight, the remaining layered plates are tightly retracted in the layered device groove and are not exposed. When the telescopic handling device transports the culture box to the lowermost layered plate, it will flatten the lowermost layered plate, thereby lifting the culture box. Synchronously, during the process of the lowermost layered plate rotating to the horizontal position, the layered rod will drive the layered plates above it to rotate, making them exposed outside the layered device groove, waiting for the arrival of the next culture box. At the same time, when the layered plate completely lifts the culture box, the handling plate is no longer under the pressure of the culture box, and the handling spring resets, thereby retracting the handling plate and disengaging it from the culture box and the culture rack.

[0021] The beneficial effects achieved by the present invention with the above structure are as follows:

[0022] 1. The kitchen waste is put into the crushing box through the feeding port. The crushing blades crush the kitchen waste, and the water therein is separated. At the same time, the kitchen waste is crushed into fine particles, forming a viscous fluid.

[0023] 2. The piston device reciprocates in the dehydration tank, which will cause alternating negative pressures on the left and right sides, enabling the one-way valves on the left and right sides to alternately put the crushed kitchen waste fluid into the dehydration tank and compress it by the piston device. At the same time, the closing plate 1 and the closing plate 2 move along with it to close the discharge pipes on their sides, thereby enabling the water in the kitchen waste fluid to be squeezed out through the dehydration plate. The squeezed-out water is discharged from the drain pipe. The dehydrated substance is more viscous and has a slower falling rate. When the next fluid to be dehydrated enters the dehydration tank, it has not completely discharged from the discharge pipe of the dehydration tank, achieving the technical effect of circulating dehydration of the kitchen waste fluid.

[0024] 3. The rotation of the turntable causes the turntable drive shaft to drive the sliding rod to move reciprocally within the sliding groove frame, thereby driving the movement of the sliding shell. When the sliding shell moves to the left, the inner wall on the right side of the sliding shell will push the piston drive rod 1 to move to the left. When the sliding shell moves to the right, the inner wall on the left side of the sliding shell will push the piston drive rod 2 to move to the right, thereby driving the piston plate 1 and the piston plate 2 to move reciprocally within the dehydration tank. And there is a piston spring between the piston plate 1 and the piston plate 2. During the process that the piston drive rod 1 drives the piston plate 1 to move to the left, it is the elastic force provided by the piston spring that pushes the piston plate 2 to move to the left. During the process that the piston plate 2 compresses the fluid-like residue of the kitchen waste after crushing, due to too much fluid-like material, the compressed volume is large, or the moisture content of the fluid-like material itself is too low to be compressed, the piston spring starts to play a buffering role to prevent the piston plate 2 from being subjected to excessive force. The same is true when it moves to the right.

[0025] 4. There is a suspended part at the tail of the conveyor frame. The support plate prevents the incubator from falling off the conveyor frame during the movement process, and when the telescopic handling device lifts the incubator from the suspended part, the support plate can be rotated to prevent the support plate from blocking the movement of the handling fixing plate.

[0026] 5. The center rotation axis of the handling fixing plate rotates within the rotation shaft sleeve of the handling conveyor belt and is driven to rotate by the handling conveyor belt. Under its own gravity, the handling fixing plate has always been in a vertical state. The handling spring makes the lifting plate at the top. When the handling plate touches the incubator, the gravity of the incubator will press down the handling plate. At the same time, the telescopic connecting rod will push out the handling plate. The handling plate extends to the center of the incubator and lifts the incubator. During the process, the sliding wheel prevents the handling plate from pushing out the incubator, and the sliding wheel will lock after being fully stressed to prevent it from rolling.

[0027] 6. When there is no incubator placed on the culture rack, the bottommost layer plate protrudes and is exposed outside the layer device groove. Under the action of the counterweight, the other layer plates are tightly retracted inside the layer device groove and are not exposed. When the telescopic handling device transports the incubator to the bottommost layer plate, it will flatten the bottommost layer plate, thereby lifting the incubator. Synchronously, during the process that the bottommost layer plate rotates to the horizontal, the layer rod will drive the layer plates above it to rotate, making them exposed outside the layer device groove and waiting for the arrival of the next incubator. At the same time, when the layer plate fully lifts the incubator, the handling plate is no longer under the pressure of the incubator, and the handling spring resets, thereby retracting the handling plate and separating it from the incubator and the culture rack.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0045] As Figures 1 - 13 shown, the present invention provides a multi-layer fly maggot breeding device for kitchen waste, including a crushing device 1, a dehydration and fermentation device 2, a conveyor rack 3, a telescopic handling component 4, and a layered culture device 5. The crushing device 1 is arranged on the dehydration and fermentation device 2, the conveyor rack 3 is arranged in front of the dehydration and fermentation device 2, the layered culture device 5 is arranged in front of the telescopic handling component 4, and the conveyor rack 3 is arranged on the side of the telescopic handling component 4. The crushing device 1 includes a crushing box 11, a crushing motor 12, a crushing shaft 13, a turntable 14, and crushing blades 15. The crushing motor 12 is arranged on the crushing box 11, the crushing shaft 13 is arranged on the crushing motor 12, the crushing shaft 13 rotates inside the crushing box 11, the crushing blades 15 are arranged on the crushing shaft 13, the crushing blades 15 rotate inside the crushing box 11, the turntable 14 is arranged at the bottom of the crushing shaft 13, the turntable 14 is arranged at the bottom outside the crushing box 11, the crushing box 11 is provided with a feeding port 111 and a discharging port 112, and the turntable 14 is provided with a turntable drive shaft 141.

[0046] Among them, the kitchen waste is put into the crushing box 11 through the feeding port 111, and the crushing blades 15 crush the kitchen waste, and the water therein is separated out. At the same time, the kitchen waste is crushed into fine particles to form a viscous fluid.

[0047] The dehydration and fermentation device 2 includes a dehydration tank 21, a one-way valve 22, a piston device 23, a piston driving device 24, and a fermentation tank 25. The dehydration tank 21 is provided with a feed pipe 211, a dehydration plate 212, a drain pipe 213, a discharge pipe 214, and a piston rod groove 215. The feed pipe 211 is connected to the discharge port 112. The one-way valve 22 is arranged in the feed pipe 211. The piston device 23 slides in the dehydration tank 21. The piston driving device 24 is arranged at the bottom of the crushing box 11. The fermentation tank 25 is arranged on the lower side of the dehydration tank 21. The fermentation tank 25 is provided with an exhaust hole 251, a discharge pipe 252, a fermentation motor 253, a support frame 254, and a discharge plate 255. The discharge pipe 214 is connected to the fermentation tank 25. The fermentation motor 253 is arranged on the discharge pipe 252. The discharge plate 255 is arranged on the discharge pipe 252.

[0048] Among them, the reciprocating movement of the piston device 23 in the dehydration tank 21 will cause alternating negative pressures on the left and right sides, enabling the one-way valves 22 on both sides to alternately input the crushed kitchen waste fluid into the dehydration tank 21, which is compressed by the piston device 23. At the same time, the closing plate one 2311 and the closing plate two 2331 move along to close the discharge pipe 214 on their sides. As a result, the water in the kitchen waste fluid is extruded through the dehydration plate 212, and the extruded water is discharged from the drain pipe 214. The dehydrated substance is more viscous and has a slower falling rate. When the next fluid to be dehydrated enters the dehydration tank 21, it has not completely discharged from the discharge pipe 214 of the dehydration tank 21, achieving the technical effect of cyclic dehydration of the kitchen waste fluid.

[0049] The piston device 23 is provided with a piston plate one 231, a piston rod one 232, a piston plate two 233, a piston rod two 234, and a piston spring 235. The piston spring 235 is arranged between the piston plate one 231 and the piston plate two 233. The piston rod one 232 is arranged on the piston plate one 231. The piston rod two 234 is arranged on the piston plate two 233. The piston rod one 232 is provided with a card slot one 2321. The piston rod two 234 is provided with a card slot two 2341. The piston rod two 234 slides on the card slot one 2321. The piston rod one 232 slides on the card slot two 2341. The piston rod one 232 slides on the card slot two 2341. The piston plate one 231 is provided with a closing plate one 2311. The piston plate two 233 is provided with a closing plate two 2331.

[0050] The piston driving device 24 includes a sliding trough frame 241, a sliding rod 242, a sliding shell 243, a first piston driving rod 244, and a second piston driving rod 245. The sliding rod 242 is provided with a sliding rod groove 2421 and a sliding connecting rod 2422. The sliding trough frame 241 is arranged on the crushing box 11. The sliding rod 242 slides on the sliding trough frame 241. The turntable driving shaft 141 slides in the sliding rod groove 2421. The sliding shell 243 is arranged on the sliding connecting rod 2422. The first piston driving rod 244 slides in the sliding shell 243. The second piston driving rod 245 slides in the sliding shell 243. The first piston driving rod 244 is arranged on the first piston rod 232. The second piston driving rod 245 is arranged on the second piston rod 234.

[0051] Wherein, the rotation of the turntable 14 causes the turntable driving shaft 141 to drive the sliding rod 242 to reciprocate in the sliding trough frame 241, thereby driving the sliding shell 243 to move. When the sliding shell 243 moves to the left, the right inner wall of the sliding shell 243 will push the first piston driving rod 244 to move to the left. When the sliding shell 243 moves to the right, the left inner wall of the sliding shell 243 will push the second piston driving rod 245 to move to the right, thereby driving the first piston plate 231 and the second piston plate 233 to reciprocate in the dehydration tank 21. And a piston spring 235 is arranged between the first piston plate 231 and the second piston plate 233. In the process of the first piston driving rod 244 driving the first piston plate 231 to move to the left, it is the elastic force provided by the piston spring 235 that pushes the second piston plate 233 to move to the left. In the process of the second piston plate 233 compressing the crushed kitchen waste fluid, due to too much fluid, the compressed volume is large, or the moisture content of the fluid itself is too low to be compressed, the piston spring 235 starts to play a buffering role to prevent the second piston plate 233 from being subjected to excessive force. The same is true when moving to the right.

[0052] The conveyor frame 3 includes a conveyor frame fixing rod 31, a conveyor frame side plate 32, a transmission rod 33, a conveyor frame motor 34, and a support plate 35. The conveyor frame side plate 32 is arranged on the conveyor frame fixing rod 31. The conveyor frame motor 34 is arranged on the conveyor frame side plate 32. The conveyor frame motor 34 drives the transmission rod 33 to rotate through a transmission chain. The transmission rod 33 rotates on the conveyor frame side plate 32.

There are four handling plate telescopic rods 4312. The telescopic plate 4313 is arranged on the middle two handling plate telescopic rods 4312. The handling plate telescopic rods 4312 slide in the fixed shaft sleeve 4331. One end of the telescopic connecting rod 432 rotates on the telescopic plate 4313, and the other end of the telescopic connecting rod 432 rotates on the handling fixing plate 434. The lifting plate sliding groove 4332 slides on the handling fixing plate 434. The lifting plate 433 slides on the positioning rod 4341. The handling spring 4343 is arranged on the positioning rod 4341, and the handling spring 4343 is arranged between the positioning base 4342 and the lifting plate 433.

[0057] Among them, the center rotation axis 4344 of the handling fixed plate 434 rotates in the rotation sleeve 4241 of the handling conveyor belt 424 and is driven by the handling conveyor belt 424 to rotate. Under its own gravity, the telescopic handling device 43 keeps the handling fixed plate 434 in a vertical state all the time. The handling spring 4343 makes the lifting plate 433 at the top. When the handling plate 431 touches the incubator 54, the gravity of the incubator 54 will press down the handling plate 431. At the same time, the telescopic connecting rod 432 will push out the handling plate 431. The handling plate 431 extends to the center of the incubator 54 to lift the incubator 54. During the process, the sliding wheel 4311 prevents the handling plate 431 from pushing out the incubator 54, and the sliding wheel 4311 will lock after being fully stressed to prevent it from rolling.

[0058] The layered culture device 5 is provided with a culture rack 51, a layered plate 52, a layered rod 53 and an incubator 54. The culture rack 51 is provided with a culture rack side plate 511, a stable cross bar 512 and a support device 513. The culture rack side plate 511 is provided with a layered device groove 5111. The stable cross bar 512 is arranged on the culture rack side plate 511. The culture rack side plate 511 is arranged on the support device 513. The layered plates 52 are arranged in an array in the layered device groove 5111. The layered rods 53 are arranged between adjacent layered plates 52. The edge of the incubator 54 is arranged on the layered plate 52.

[0059] The layered plate 52 is provided with a counterweight 521, a layered plate rotation axis 522 and a layered plate rotation rod 523. The counterweight 521 is arranged outside the layered plate 52. The layered rod 53 is provided with a layered rod sliding groove 531 and a layered rod rotation hole 532.

[0060] Among them, when the incubator 54 is not placed on the culture rack 51, the lowermost layered plate 52 protrudes and is exposed outside the layered device groove 5111. Under the action of the counterweight 521, the remaining layered plates 52 are tightly retracted in the layered device groove 5111 without being exposed. When the telescopic handling device 43 transports the incubator 54 to the lowermost layered plate 52, it will flatten the lowermost layered plate 52, thereby lifting the incubator 54. Synchronously, during the process of the lowermost layered plate 52 rotating to the horizontal, the layered rod 53 will drive the layered plate 52 above it to rotate, making it exposed outside the layered device groove 5111 to wait for the arrival of the next incubator 54. At the same time, when the layered plate 52 fully lifts the incubator 54, the handling plate 431 no longer receives the pressure of the incubator 54, and the handling spring 4343 resets, thereby retracting the handling plate 431 and separating it from the incubator 54 and the culture rack 51.

[0061] During specific use, the kitchen waste is put into the crushing box 11 through the feeding port 111. The crushing motor 12 drives the crushing shaft 13 to rotate, and the crushing shaft 13 drives the crushing blades 15 to rotate. Then, the crushing blades 15 crush the kitchen waste to form a viscous fluid. At the same time, the crushing shaft 13 drives the turntable 14 to rotate, and the turntable drive shaft 141 rotates following the turntable 14. The turntable drive shaft 141 drives the movement of the sliding rod groove 2421 of the sliding rod 242, so that the sliding rod 242 makes a reciprocating movement in the sliding groove frame 241. At the same time, the sliding connecting rod 2422 of the sliding rod 242 drives the sliding shell 243 to reciprocate. When the sliding shell 243 moves to the left, the inner wall on the right side of the sliding shell 243 will push the piston drive rod one 244 to move to the left. The piston drive rod one 244 drives the piston plate one 231 to move to the left in the dehydration tank 21. The piston plate one 231 pushes the piston spring 235, and the elastic force provided by the piston spring 235 pushes the piston plate two 233 to move to the left in the dehydration tank 21. The closing plate two 2331 closes the discharge pipe 214 on the left side of the dehydration tank 21. At the same time, a negative pressure is generated on the right side of the dehydration tank 21, and the one-way valve 22 opens. The kitchen waste fluid flows from the discharge port 112 of the crushing box 11 and the feed pipe 211 of the dehydration tank 21 into the right side of the dehydration tank 21. When the sliding shell 243 moves to the right, the inner wall on the left side of the sliding shell 243 will push the piston drive rod two 245 to move to the right. Then, the piston drive rod two 245 drives the piston plate two 233 to move to the right. The piston plate two 233 pushes the piston spring 235, and the elastic force of the piston spring 235 pushes the piston plate one 231 to move to the right in the dehydration tank 21. The closing plate one 2311 will close the discharge pipe 214 on the right side of the dehydration tank 21. The piston plate one 231 compresses the kitchen waste fluid, and the water in the kitchen waste fluid is separated out, flows into the drain pipe 213 through the dehydration plate 212 and is discharged. Similarly, a negative pressure is generated on the left side of the dehydration tank 21, and the kitchen waste fluid enters the dehydration tank 21 and is compressed by the piston plate two 233 to squeeze out the water. The closing plates under the piston plate one 231 and the piston plate two 233. The dehydrated kitchen waste enters the fermentation tank 25 through the discharge pipe 214 for fermentation to form a culture for maggots. The culture box 54 containing maggot larvae is placed on the conveyor rack 3 and moves. The conveyor rack motor 34 drives the transmission rod 33 to rotate through the transmission chain. Then, the transmission rod 33 drives the culture box 54. When the culture box 54 passes by the discharge plate 255, the fermentation motor 253 on the discharge pipe 252 of the fermentation tank 25 starts, and the maggot culture is discharged from the discharge plate 255 and enters the culture box 54. The culture box 54 moves further forward. When the culture box 54 moves to the end of the conveyor rack 3, the support plate 35 will support the side of the culture box 54 to prevent it from falling.

[0062] The conveying motor 421 drives the motor shaft 4211 to rotate. The motor shaft 4211 drives the motor gear 4212 to rotate. The motor gear 4212 drives the transmission gear 4221 to rotate, and then drives the driving transmission wheel 4222 to rotate. The driving transmission wheel 4222 drives the transmission wheel 423 to rotate, and then drives the conveying conveyor belt 424 to rotate. The rotating shaft sleeve 4241 of the conveying conveyor belt 424 drives the conveying fixing plate 434 to rotate, and then the telescopic conveying device 43 moves. When the telescopic conveying device 43 moves to the position of the incubator 54 at the tail of the conveying rack 3, the gravity of the incubator 54 gives pressure to the conveying plate 431. The conveying plate 431 drives the lifting plate 433 to move downward. The lifting plate sliding groove 4332 slides on the conveying fixing plate 434, and the conveying spring 4343 is compressed. At the same time, the telescopic connecting rod 432 pushes the telescopic plate 4313 to slide out, and then the conveying plate telescopic rod 4312 moves outward from the fixed shaft sleeve 4331. The sliding wheel 4311 rotates at the bottom of the incubator 54. When the lifting plate 433 moves to the bottom end of the conveying fixing plate 434, the conveying plate 431 extends to the center position of the incubator 54. As the conveying conveyor belt 424 rotates, the incubator 54 is lifted and rotated to the layered culture device 5. Initially, no incubator 54 is placed on the culture rack 51. The bottommost layered plate 52 protrudes and is exposed outside the layered device groove 5111. The other layered plates 52 are tightly retracted in the layered device groove 5111 under the action of the counterweight 521 and are not exposed. When the telescopic conveying device 43 transports the incubator 54 to the bottommost layered plate 52, the bottommost layered plate 52 will be flattened, and then the incubator 54 is lifted. Synchronously, during the process of the bottommost layered plate 52 rotating to the horizontal position, the layered rod 53 will drive the layered plate 52 above it to rotate, making it exposed outside the layered device groove 5111 and waiting for the arrival of the next incubator 54. At the same time, when the layered plate 52 completely lifts the incubator 54, the conveying plate 431 no longer receives the pressure of the incubator 54, and the conveying spring 4343 resets, and then the conveying plate 431 is retracted, disengaging from the incubator 54 and the culture rack 51.
