[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, a method for three-dimensional efficient breeding of black-spotted sidefold frogs includes the following steps: first, the buckle 26 on the upper net box 24 is embedded in the slot 27 of the bottom chassis 25, so that the upper net box 24 and the bottom chassis 25 are combined into the net box 23, and the net box 23 is placed on the bottom tray 17, and the first electric motor 15 is started, and the first chain 32 is pulled to drive the bottom tray 17 to move upward to a suitable height. At this time, the motor under the crawler of the bottom tray 17 works, and the crawler drives the net box 23 to move toward the frame layer 16, and the motors under the crawlers of the corresponding first crawler conveyor 18, the second crawler conveyor 19 and the third crawler conveyor 20 work respectively, and the net box 23 can be pulled into their respective frame layers 16.

[0030] The second motor 5, the second chain 6 and the horizontal grid plate 34 on the right side work in the same way.

The second electric motor 5 works to drive the cross grid 28 to move up and down, and then the net cage 23 is manually pushed into the iron shell 7 at a suitable height, and the movement is cyclical.

[0033] After the net box 23 enters the frame layer 16, the water pump 11 transports the connected groundwater to the internal pipe 22 through the pipe 14, and the spraying device 21 is connected to 22 for spraying.

[0034] During feeding, the net cage 23 moves onto the bottom tray 17, and the bait in the bait trough 12 flows into the net cage 23 through the opening 32 on the shell along the funnel.

[0035] During cleaning, the net box 23 is moved to the horizontal grid plate 34, the buckle 26 and the slot 27 are manually separated, and the horizontal grid plate 34 sinks into the water tank 3 under the operation of the second electric motor 5. The brush electric motor 30 drives the pulley 31 to move along the track groove 29, driving the brush 4 to move for cleaning, and the cleaned sewage is discharged from the pipe 10.

[0036] After cleaning, the buckle 26 is manually engaged with the slot 27 and the whole conveyor returns to the device to continue operation.

[0037] Example 3: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a method for three-dimensional efficient breeding of black-spotted sidefold frogs comprises the following steps:

[0038] The conveying device includes a device powered by a first electric motor 15 and a second electric motor 5 .

[0039] The conveying device can be set at a time or can be manually controlled. The first electric motor 15 pulls the chain 6 to drive the bottom tray 17 to move up and down. When it reaches a suitable height, the motor under the track of the bottom tray 17 will drive the net box 23 to enter the frame 16. At this time, the motors under the first crawler conveyor 18, the second crawler conveyor 19 and the third crawler conveyor 20 of the corresponding height will drive the net box 23 to move. Set 12 hours (or select any time exceeding 12 hours) to change the position of the net box 23.

[0040] The tray 17 moves to the corresponding height of the third crawler conveyor 20, the cross grid plate 28 moves to the corresponding height of the third crawler conveyor 20, the leftmost net box 23 on the third crawler conveyor 20 is driven to the tray 17 by the crawler moving to the left, the rightmost net box 23 on the second crawler conveyor 19 moves to the right to the cross grid plate 28, the second electric motor 5 and the first electric motor 15 work, and the tray 17 is driven to the height of the second crawler conveyor 19, the cross grid plate 28 is lowered to the height of the third crawler conveyor 20, the crawler 17 moves to the right, and the second crawler conveyor 19 moves to the right to drag the net box 23 into the second Crawler conveyor 19, manually check the net box 23 on the cross grid plate 28 and then manually push the cross grid plate 28 into the third crawler conveyor 20, the crawler of the third crawler conveyor 20 moves to the left to drag the net box 23 into the third crawler conveyor 20, repeat n times, n is the number of net boxes on a single-layer crawler, after which the second crawler conveyor 19 and the third crawler conveyor 20 have all completed the swap of the net boxes 23, at this time, the crawler of the first crawler conveyor 18 and the crawler of the second crawler conveyor 19 repeat the above actions to complete the position change of the net box 23 of the first crawler conveyor 18 and the second crawler conveyor 19.

[0041] The net cage 23 is an integral breeding net cage. The bait is poured into the side bait box 12 and fed twice a day. When feeding, the bait is poured into the net cage 23 from the side bait trough and contacts the elastic net 25 at the bottom of the net cage. The bait bounces up to lure the frogs to eat. The bait is fed according to the growth status of the frogs in the net cage 23, and the amount of bait at a time is about 5% of the total weight of the frogs.

[0042] The same applies to the administration of drugs when an epidemic is discovered.

[0043] When the temperature and humidity are too low, the spray device 21 connected to the top pipe of each layer will spray to moisten the frog body and ensure the humidity in the box. The spraying amount depends on the state of the day, so as to keep the frog body moist and the box body not too humid. The spray device can also add drugs to quarantine or apply medicine to the frog.

[0044] The cleaning of the mesh cages is automated, and the entire mesh cage is cleaned once a week. The mesh cages are transferred to the side by means of the crawler belt. From the above explanation of the operation of the mesh cages 23, it can be known that each mesh cage 23 can be run onto the cross grid plate 28, and the second electric motor 5 moves to bring the cross grid plate 28 and the mesh cage 23 into the groove. After the buckles 26 and the slots 27 are manually separated, the bottom chassis 25 sinks to the bottom, and the motor 30 is started to drive the brush to scrub the bottom chassis 25. After the cleaning is completed, the cross grid plate 28 moves upward, and after the buckles 26 and the slots 27 are manually closed, the cleaned mesh cages 23 are manually pushed into the frame layer 16, and the crawler belt moves to send the next mesh cage 23 to be cleaned into the cross grid plate 28. The above steps are repeated to transfer the mesh cage 23 to the side by means of the crawler belt. The right side of the iron shell 7 is hollow, and the crawler belt can move to the cross grid plate 28 and leave the shell 7.

[0045] The second electric motor 5 works, driving the second chain 6 to move the bottom horizontal grid plate 34 up and down. When the net box 23 enters the horizontal grid plate 34, 34 is sent down to the groove 3. At this time, the net cage 24 and the bottom chassis 25 of the net box body are separated, and the brush electric motor 30 is started. The pulley 31 is installed at the lower part of the electric motor, and the brush 4 is driven along the track groove 29 for cleaning. After cleaning, the frog is re-installed into the net box 23, and the buckle 26 is engaged with the card groove 27. After the net box 23 is engaged, it is sent into the inner cavity of the iron shell 7 by the first electric motor 15 for transmission again.

[0046] Arrange manual inspection once a day, at the end of the second feeding, check the status of the frogs in the cage 23, quarantine, check the operation of the equipment, start the spray device to spray the residual bait inside the cage 23, and then start the conveying device to check all the cages. If there is an epidemic, the cage 23 will be given medicine, and all the cages 23 will be sprayed for quarantine. If there is too much residual bait in the cage 23, it needs to be conveyed to the cleaning device (on the right) for cleaning.

[0047] When using this integrated breeding device for black-spotted side-folded frogs, first, connect the constant temperature heating system below, pump groundwater with a relatively constant underground temperature up through the water pump 11 and enter the pipe 22, preheat the pipe to heat up the inside of the device, turn on the spray system 21 to moisten the net cage, open the special net cage 23, separate the special box body 24 from the base 25, install an elastic net 25 at the bottom that can make the bait bounce, put the black-spotted side-folded frog in, fit the slots 26 and 27, fit the box body 24 with the base 25, put it in the device, and transmit it to any position in the device through the transmission device.

[0048] The rotation rate and frequency are set to replace the position of a whole layer of cages 23 every three hours.

[0049] Pour the bait into the side feeder 12, set the dosage and time to ensure that the bait amount is about 5% of the total weight of the frog, feed it twice a day at a fixed time, and automatically switch to the next net cage after one box is fed. The bait enters the net cage 23 and falls into the elastic net 25 at the bottom, which bounces up and down, luring the black-spotted sidefold frog to eat. When the moving box is switched, the elastic net is inertially fluctuated to make the bait bounce up, and it stops after half an hour of continuous rotation. At this time, the spray device 21 starts humidification to flush the residual bait.

[0050] A manual inspection is carried out once a day. After the second feeding, the transmission device is started to observe the status of the black-spotted side-folded frogs in each box and the residual bait, and the disabled and diseased individuals are taken out. The net cages 23 with too much residual bait are transferred to the cleaning device for cleaning. When diseases are found, edible medicines are added to the feeder 12 or a single net cage 23 as appropriate. The top of the spray device 21 can be added with a proportioned agent to spray the medicine. After flushing the pipeline, normal humidification spraying can be carried out.

[0051] The cleaning device is located on the side of the entire device. It is lowered by the conveyor device, and the lower buckle is released to separate the box from the base. The internal elastic net can be taken out for cleaning, and multiple nozzles and brushes on the side are started to clean the box.

[0052] After cleaning, the box body is reassembled and sent back to the transmission device.

[0053] The net cage 23 is automatically cleaned once a week and cleaned after manual inspection when necessary.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
