Description

Technical Field

[0001] The invention belongs to the technical field of circular breeding and cultivation, and specifically relates to an ecological circular breeding and cultivation method for vegetables, frogs, rice and black soldier flies. Background Art

[0002] With the continuous advancement of cultivation technology, the growth period of vegetables has become shorter and shorter. With the intensification of environmental pollution, vegetable diseases and insect pests have become more and more serious. Most vegetables need to be treated with pesticides for many times before they can mature and be put on the market. At present, the pest control in the production of pollution-free vegetables mainly uses methods such as light trapping, water and fertilizer drip irrigation, and low-residue biological pesticide spraying. It is also possible to use the laws of nature to catch and kill pests through frogs, while also achieving the purpose of weeding, soil loosening and fertilization.

[0003] At present, there are few frogs raised in vegetable fields. Most ecological breeding is integrated rice and frog breeding, mainly to achieve a double harvest of rice and frogs. That is, frog ponds and feeding platforms are built in rice fields, and a double harvest of rice and frogs is achieved through rice-tobacco rotation.

[0004] In the prior art, a Chinese patent discloses a feeding device for ecological breeding of rice frogs (publication number: CN218126422U), whose main structure includes a chassis, a guide rod, a discharge bin, a discharge pipe, a discharge tray, a spring, a glass sheet, a dispersion component and a blocking component. The top side of the chassis is connected to the guide rod, the top of the guide rod is connected to the discharge bin, the bottom of the discharge bin is penetrated by the discharge pipe, the upper sliding sleeve of the guide rod is provided with a discharge tray located directly below the discharge bin, a spring is connected between the discharge tray and the chassis, and glass sheets for observing the remaining feed are embedded on the front and rear sides of the discharge bin, and a dispersion component for dispersing feed and a blocking component for blocking feed are provided on the discharge bin.

[0005] In actual use, the above patent allows the feed in the feed bin to flow into the feed frame, and the feed in the feed frame flows into three feed pipes respectively, and then is discharged to the feed plate in a limited amount by the feed limiting pipe, so as to feed the rice frog evenly and slowly. However, there are still corresponding disadvantages in actual use: in the ecological breeding process of frogs, frogs can be fed with traditional feed and small insects. When small insects are used as feed to feed frogs, some of the small insects are squeezed and collided and inactivated during transportation. The inactivated small insects are not easy to attract the observation of frogs, and are therefore not easy to be eaten by frogs. In the use of the above patent, when small insects are put in to feed frogs, the inactivated insects that are not eaten by frogs are prone to deterioration and harm to frogs.

[0029] Beneficial effects

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. The present invention adopts the coordinated design of structures such as the feeding platform and the recovery mechanism, and the operator controls the operation of the driving mechanism through an external control system. The driving mechanism drives the aggregate shell to rotate forwardly. When the aggregate shell rotates forwardly, the driving sleeve moves downward, and the sleeve can push the guide shell to move downward. When the guide shell moves downward, it drives the blocking block to separate from the feeding channel. At the same time, when the aggregate shell rotates, it drives the cleaning rod to rotate circumferentially to clean the inactivated black soldier fly larvae that have not been eaten by frogs in the feeding trough, so that the inactivated black soldier fly larvae pass through the feeding channel and the guide hole and fall into the guide shell. When the guide shell continues to move downward so that the discharge port coincides with the docking port, the inactivated black soldier fly larvae of the guide shell enter the aggregate shell through the docking port for collection, and the inactivated black soldier fly larvae can be recovered, thereby improving the safety of feeding frogs and solving the problem in the prior art that when small insects are put in to feed frogs, the inactivated insects that are not eaten by frogs are prone to deterioration and cause harm to frogs.

[0032] 2. The present invention adopts the coordinated design of structures such as the aggregate shell, the driving mechanism, and the mixing and feeding mechanism. When the operator controls the driving motor to operate in the forward direction to drive the aggregate shell to rotate through the external control system, the external control system synchronously controls the electromagnetic valve to open through the sensor, so that the feed in the storage shell can fall. When the external control system controls the driving motor to operate in the reverse direction to drive the aggregate shell to rotate, the external control system synchronously controls the electromagnetic valve to close through the sensor to stop the feed in the storage shell from falling. At the same time, when the driving motor drives the aggregate shell to rotate in the reverse direction, under the action of the docking wheel and the driven wheel, the spiral rod can rotate in the forward direction opposite to the rotation direction of the aggregate shell. When the spiral rod rotates in the forward direction, the mixed feed can be transported to the upper part of the inner cavity of the feed barrel through the feed hole, and discharged through the discharge hole to fall into the feeding trough again. When the spiral rod rotates, it drives the dividing rod to rotate circumferentially, so as to divide the mixed feed in the feed barrel and the discharge hole, so as to avoid the mixed feed from forming long strips when it is discharged and being inconvenient for frogs to eat, thereby improving resource utilization, reducing the cost of feeding frogs, and avoiding the problem of resource waste.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figures 1 to 10 As shown, the present invention provides an ecological cycle breeding method for vegetables, frogs, rice, and black soldier flies. The specific steps of the cycle breeding method are as follows:

[0046] S1: Vegetable planting is divided into aquatic vegetable areas and conventional vegetable areas. The breeding base has a tropical and subtropical monsoon climate and is regulated by the marine climate all year round. There is no severe cold in winter and no scorching heat in summer. The annual average temperature is 22.7℃~23.5℃. Frogs almost have no hibernation period throughout the year and can lay eggs as long as there is water all year round. It takes about 3-4 months from egg laying to froglets, and about 3-4 months from froglets to adult frogs, which is equivalent to the time of one crop of vegetables. Aquatic vegetables mainly grow lotus roots, water celery, and water chestnuts, and a small amount of algae is added. Conventional vegetable planting areas mainly rotate beans, eggplants, root vegetables and melon vegetables, and also grow one crop of rice every year;

[0047] S2: Set up the aquatic vegetable area as a frog breeding and hatching area, and set up the conventional vegetable area as a frog breeding area. Frogs can be used to control pests in the vegetable planting area. The number of frogs released in the breeding area is determined by the amount required to achieve the insect control effect during vegetable planting. The stocking amount per mu is 2000-3000. In the aquatic vegetable area, male and female frogs are released in a 1:1 ratio, and 30 pairs of breeding frogs are released per mu;

[0048] S3: A 200-acre black soldier fly breeding area is set up next to the vegetable planting area, and the black soldier fly larvae produced are used to fatten frogs;

[0049] S4: A feeding table 1 is set up in the aquatic vegetable area, and the operator places the produced black soldier fly larvae on the feeding table 1 for feeding the frogs;

[0050] S5: Vegetables are planted in the conventional vegetable area from January to April, rice is planted from May to August, and vegetables are planted from September to December to achieve rotation. The frogs in the conventional vegetable area are captured after they mature, and the captured mature frogs are placed in the aquatic vegetable area for breeding and fattening. After that, the young frogs in the aquatic vegetable area are placed in the conventional vegetable area for breeding to achieve circular planting and breeding;

[0051] The operation process in step S4 of the above-mentioned circular breeding method needs to be completed by the feeding table 1.

[0052] The feeding table 1 includes a placing shell 2, a recovery mechanism 3 arranged inside the placing shell 2 for cleaning the inactivated black soldier flies, a driving mechanism 4 arranged at the lower part of the inner cavity of the placing shell 2 for driving the recovery mechanism 3 to operate, and a mixing feeding mechanism 5 arranged on the recovery mechanism 3;

[0053] A feeding trough 6 is provided on the upper surface of the placement shell 2, and a water inlet mechanism 7 is provided on the inner side wall of the feeding trough 6;

[0054] The recycling mechanism 3 includes an aggregate housing 31 movably installed on the top surface of the inner cavity of the placement housing 2 through bearings, docking ports 32 circumferentially and equidistantly formed on the lower part of the outer surface of the aggregate housing 31, a material guiding housing 33 movably sleeved on the outer surface of the aggregate housing 31, material discharging channels 34 circumferentially and equidistantly formed on the bottom surface of the inner cavity of the feeding trough 6, a blocking block 35 fixed on the upper surface of the material guiding housing 33 and adapted to the material discharging channels 34, material guiding holes 36 formed on the upper surface of the material guiding housing 33 between adjacent two blocking blocks 35, a discharging port 37 circumferentially formed on the lower part of the inner ring of the material guiding housing 33, and a sleeve 38 threadedly sleeved on the outer surface of the aggregate housing 31 above the material guiding housing 33;

[0055] Among them, the top surface of the aggregate housing 31 penetrates above the feeding trough 6, and the top surface of the aggregate housing 31 is conical. Cleaning rods 39 are circumferentially and equidistantly fixedly installed on the upper part of the outer surface of the aggregate housing 31. The bottom surface of the cleaning rods 39 is movably connected to the bottom surface of the inner cavity of the feeding trough 6. Two spring compression rods 310 are vertically and symmetrically fixedly installed on the bottom surface of the inner cavity of the placement housing 2. The output ends of the spring compression rods 310 are fixedly connected to the bottom surface of the material guiding housing 33. Two vertical rods are vertically and symmetrically fixedly installed on the top surface of the inner cavity of the placement housing 2. The vertical rods penetrate through the sleeve 38 and the material guiding housing 33. The bottom surface of the sleeve 38 is movably connected to the upper surface of the material guiding housing 33.

[0056] When in use, the feeding table 1 is placed in the water in the aquatic vegetable area so that the upper surface of the placement shell 2 is slightly above the water surface, the black soldier fly larvae are placed in the feeding trough 6, and the water from the aquatic vegetable area is passed into the feeding trough 6 through the water inlet mechanism 7. The surviving black soldier fly larvae float on the water surface in the feeding trough 6, and the inactivated black soldier fly larvae sink to the bottom of the water (wherein, if the black soldier fly larvae that have not been eaten by the frogs have been inactivated, the insect body density will increase due to the increase in water, and after exceeding the buoyancy threshold of the water body, they will naturally sink to the bottom of the feeding trough 6, and the frog's visual system is sensitive to dynamic objects. The larvae that sink to the bottom are difficult to be detected by the frog due to the lack of movement characteristics, thereby avoiding the inactivated larvae from being eaten by the frog), which is convenient for the frog to eat the surviving black soldier fly larvae. When the frog finishes eating, the operator controls the operation of the driving mechanism 4 through the external control system, and the driving mechanism 4 drives the aggregate shell 31 to rotate forward. When the aggregate shell 31 rotates forward, the sleeve 38 is driven to rotate. When the guide shell 33 moves downward, the sleeve 38 can push the guide shell 33 to move downward. When the guide shell 33 moves downward, the blocking block 35 is separated from the feeding channel 34. At the same time, when the collection shell 31 rotates, the cleaning rod 39 is driven to rotate circumferentially to clean the inactivated black soldier fly larvae that are not eaten by the frogs in the feeding trough 6 (in order to prevent the inactivated larvae from deteriorating in the feeding trough 6 and causing harm to the frogs, the inactivated black soldier fly larvae that are not eaten by the frogs in the feeding trough 6 are cleaned. The inactivated black soldier fly larvae are made to pass through the feed channel 34 and the feed guide hole 36 and fall into the feed guide shell 33. When the feed guide shell 33 continues to move downward so that the discharge port 37 coincides with the docking port 32, the inactivated black soldier fly larvae of the feed guide shell 33 enter the collection shell 31 through the docking port 32 and are collected. The inactivated black soldier fly larvae can be recovered, thereby improving the safety of feeding frogs and avoiding the problem that inactivated insects that are not eaten by frogs are prone to deterioration and harm to frogs.

[0057] It is worth noting that when the aggregate shell 31 rotates forward to drive the mixing and feeding mechanism 5 to operate, the mixing and feeding mechanism 5 can sprinkle traditional feed into the bottom of the inner cavity of the aggregate shell 31 and mix it with the recovered inactivated black soldier fly larvae (even if the black soldier fly larvae are inactivated, they are still rich in nutrients such as protein, and if the inactivated black soldier fly larvae are left stationary for a long time, they are prone to deterioration and produce harmful substances. Therefore, they are reasonably utilized before they deteriorate, and the black soldier fly larvae are reused by mixing them with feed and re-feeding frogs). Then, the driving mechanism 4 is controlled to drive the aggregate shell 31 to rotate in the opposite direction. When the aggregate shell 31 rotates in the opposite direction, the mixing and feeding mechanism 5 can be driven to re-feed the feed mixed with inactivated black soldier fly larvae in the inner cavity of the aggregate shell 31 into the feeding trough 6 for frogs to eat, thereby improving resource utilization, reducing the cost of feeding frogs, and avoiding the problem of resource waste.

[0058] like Figure 5As shown, the driving mechanism 4 includes an annular plate 41 coaxially fixedly mounted on the bottom surface of the aggregate shell 31, a driving motor 42 fixed to the bottom surface of the inner cavity of the placement shell 2 and located outside the annular plate 41, and a driving wheel 43 fixed to the output shaft end of the driving motor 42 for driving the annular plate 41 to rotate; wherein the driving motor 42 is a waterproof motor.

[0059] When in use, the operator can control the rotation direction of the drive motor 42 through an external control system. When the drive motor 42 is in operation, the drive wheel 43 rotates. The rotation of the drive wheel 43 drives the annular plate 41 to rotate. The rotation of the annular plate 41 can drive the aggregate shell 31 to rotate.

[0060] like Fig. 9 As shown, the water inlet mechanism 7 includes a water inlet channel 71 equidistantly arranged on the inner wall of the feeding trough 6 in the circumferential direction, a sealing plate 72 vertically moving in the inner cavity of the water inlet channel 71, a support rod 73 vertically fixed to the bottom surface of the sealing plate 72, and a compression spring 74 movably sleeved on the support rod 73;

[0061] Among them, the bottom end of the support rod 73 penetrates into the inner cavity of the placement shell 2, and the bottom end of the support rod 73 is movably connected to the upper surface of the material guide shell 33, and the upper and lower ends of the compression spring 74 are fixedly connected to the top surface of the inner cavity of the placement shell 2 and the lower part of the support rod 73 respectively.

[0062] During use, when the material guide shell 33 moves downward, the support rod 73 can drive the sealing plate 72 to move downward under the elastic force of the compression spring 74, and the sealing plate 72 can seal the water inlet channel 71, thereby preventing water from the aquatic vegetable area from entering the feeding trough 6 through the water inlet channel 71.

[0063] like Figure 3 , Figure 8 As shown, the mixing feeding mechanism 5 includes a feeding cylinder 51 vertically fixed to the bottom surface of the inner cavity of the aggregate shell 31, a spiral rod 52 movably installed in the inner cavity of the feeding cylinder 51 through a bearing, a storage shell 53 fixedly sleeved on the middle part of the outer surface of the feeding cylinder 51, feeding holes 54 equidistantly arranged at the lower part of the outer surface of the feeding cylinder 51, discharging holes 55 equidistantly arranged at the upper part of the outer surface of the feeding cylinder 51, dividing rods 56 symmetrically fixedly installed on the left and right sides of the upper part of the spiral rod 52, and a material blocking mechanism 8 arranged on the upper surface of the aggregate shell 31;

[0064] Among them, a docking wheel 57 is rotatably installed on the bottom surface of the placement shell 2 through a rotating shaft, and the outer ring of the docking wheel 57 is movably connected to the inner ring of the annular plate 41, and the bottom end of the spiral rod 52 penetrates to the bottom of the aggregate shell 31, and a driven wheel 58 is fixedly sleeved on the lower part of the spiral rod 52, and the outer ring of the driven wheel 58 is movably connected to the outer ring of the docking wheel 57, and the outer surface of the feed cylinder 51 is located below the storage shell 53 and has water filter holes equidistantly opened in the circumference, and a group of solenoid valves 9 for controlling the discharge of feed are circumferentially arranged on the bottom surface of the storage shell 53, and a sensor 10 with a built-in power supply for controlling the opening and closing of the solenoid valve 9 is fixedly installed on one side of the bottom surface of the storage shell 53, and the sensor 10 and the drive motor 42 are both connected to the external control system, and a feeding port is circumferentially opened on the top surface of the storage shell 53, and a group of feeding channels are equidistantly opened on the upper surface of the aggregate shell 31, and a cover plate is arranged in the inner cavity of the feeding channel.

[0065] When in use, the operator controls the driving motor 42 to operate in the forward direction through the external control system to drive the aggregate shell 31 to rotate, and the external control system synchronously controls the electromagnetic valve 9 to open through the sensor 10, so that the feed in the storage shell 53 can fall. When the external control system controls the driving motor 42 to operate in the reverse direction to drive the aggregate shell 31 to rotate, the external control system synchronously controls the electromagnetic valve 9 to close through the sensor 10 to stop the feed in the storage shell 53 from falling. At the same time, when the driving motor 42 drives the aggregate shell 31 to rotate in the reverse direction, under the action of the docking wheel 57 and the driven wheel 58, the spiral The forward rotation of the rod 52 is opposite to the rotation direction of the aggregate shell 31. When the screw rod 52 rotates forward, the mixed feed can be transported to the upper part of the inner cavity of the feed cylinder 51 through the feed hole 54, and discharged through the discharge hole 55 and fall into the feeding trough 6 again. When the screw rod 52 rotates, it drives the dividing rod 56 to rotate circumferentially, which can divide the mixed feed in the feed cylinder 51 and the discharge hole 55, so as to avoid the mixed feed from forming long strips when it is discharged and is not convenient for frogs to eat (wherein, the feed is a processed floating feed, and a porous structure is formed inside the feed, which has a low density and can float on the water surface, and the mixed feed is not easy to be eaten by frogs). The proportion of floating feed in the feed is larger than that of black soldier fly larvae, and after being divided by the dividing rod 56, the mixed feed is cut into very small pieces, and the smaller feed particles are small in size, so that the gravity on the feed particles is reduced, and at the same time, its surface area is relatively increased, and the contact with water is more complete, and the buoyancy effect in the water body is more obvious, so that the mixture can float and avoid sinking to the bottom; on the other hand, when frogs hunt, they are more likely to find and ingest these small particles of floating feed, which improves the feeding efficiency of frogs on the mixed feed and ensures the effective use of the feed). During movement, excess water carried by the mixed feed can be easily discharged through the water filter holes (since the mixed feed contains ingredients such as inactivated black soldier fly larvae, it often carries excess water, which will increase the overall weight of the mixed feed. Therefore, after the excess water is discharged through the water filter holes, the water content of the mixed feed is reduced, so that the overall weight of the mixed feed is reduced and the degree of adhesion is reduced. In the water body of the feeding trough 6, the feed particles can be more fully dispersed, increasing the contact area with the water, and the mixed feed can easily float in the feeding trough 6, effectively avoiding the phenomenon of sinking to the bottom, ensuring that the frogs feed).

[0066] As shown in 10, the material blocking mechanism 8 includes an annular groove formed on the upper surface of the aggregate shell 31, an annular enclosure 81 that moves up and down in the inner cavity of the annular groove, two linkage rods 82 symmetrically and vertically fixed to the bottom surface of the annular enclosure 81, and a rotating rod 83 that is rotatably installed in the aggregate shell 31 through a rotating shaft;

[0067] Among them, one end of the rotating rod 83 passes through the inner cavity of the aggregate shell 31, and the bottom surface of one end of the rotating rod 83 is movably connected to the upper surface of the sleeve 38, and the bottom end of the connecting rod 82 is fixedly installed with a pin shell, and the other end of the rotating rod 83 is movably connected to the inner cavity of the pin shell. A tension spring 84 is movably sleeved on the connecting rod 82, and the upper and lower ends of the tension spring 84 are respectively fixedly connected to the top surface of the inner cavity of the aggregate shell 31 and the top surface of the pin shell.

[0068] When in use, under the pulling force of the tension spring 84, the annular enclosure 81 can be driven upward by the connecting rod 82 to enclose the mixed feed discharged from the discharge hole 55. When the aggregate shell 31 rotates in the opposite direction to drive the sleeve 38 to move upward, the guide shell 33 drives the blocking block 35 to combine with the discharge channel 34 under the elastic force of the spring compression rod 310. As the sleeve 38 continues to move upward and contact the rotating rod 83, it can push the rotating rod 83 to rotate. When the rotating rod 83 rotates, the connecting rod 82 can be driven by the pin shell to drive the annular enclosure 81 to move downward and embed into the annular groove. After that, the mixed feed can slide into the feeding trough 6 for the frogs to eat.

[0069] The working principle and use process of the present invention:

[0070] When in use, first place the feeding table 1 in the water in the aquatic vegetable area so that the upper surface of the placement shell 2 is slightly higher than the water surface, which can prevent the water in the aquatic vegetable area from submerging the placement shell 2 and causing the black soldier fly larvae in the feeding trough 6 to escape. At the same time, the frog can easily climb onto the placement shell 2 to eat in the water. The water in the aquatic vegetable area enters the feeding trough 6 through the water inlet channel 71. The surviving black soldier fly larvae float on the water surface in the feeding trough 6, and the inactivated black soldier fly larvae sink to the bottom of the water, which is convenient for the frog to eat the surviving black soldier fly larvae. Placing the black soldier fly larvae in the feeding trough 6 can facilitate the frog to eat. When the frog finishes eating, the operator controls the drive motor 42 to rotate forward through the external control system. The drive motor 42 rotates through the drive wheel 43 and The annular plate 41 drives the aggregate shell 31 to rotate forwardly. When the aggregate shell 31 rotates forwardly, the sleeve 38 is driven to move downward. The sleeve 38 can push the guide shell 33 to move downward. When the guide shell 33 moves downward, it drives the blocking block 35 to separate from the discharge channel 34. At the same time, when the aggregate shell 31 rotates, it drives the cleaning rod 39 to rotate circumferentially to clean the inactivated black soldier fly larvae that have not been eaten by frogs in the feeding trough 6, so that the inactivated black soldier fly larvae and the water in the feeding trough 6 pass through the discharge channel 34 and the guide hole 36 and fall into the guide shell 33. At the same time, when the guide shell 33 moves downward, the support rod 73 can drive the sealing plate 72 to move downward under the elastic force of the compression spring 74, and the sealing plate 72 can seal the water inlet channel 71, so as to prevent the water in the aquatic vegetable area from passing through the water inlet channel 71. 1 enters the feeding trough 6, and at the same time, after the sleeve 38 moves downward, under the pulling force of the tension spring 84, the annular enclosure 81 can be driven to rise through the connecting rod 82. When the guide shell 33 continues to move downward to make the discharge port 37 coincide with the docking port 32, the inactivated black soldier fly larvae of the guide shell 33 enter the aggregate shell 31 through the docking port 32 for collection, and when the operator controls the drive motor 42 to operate forward through the external control system to drive the aggregate shell 31 to rotate, the external control system synchronously controls the electromagnetic valve 9 to open through the sensor 10, so that the feed in the storage shell 53 can fall. When the external control system controls the drive motor 42 to operate in the reverse direction to drive the aggregate shell 31 to rotate, the external control system synchronously controls the electromagnetic valve 9 to close through the sensor 10, stopping the feed in the storage shell 53 from falling. When the driving motor 42 drives the aggregate shell 31 to rotate in the opposite direction, under the action of the docking wheel 57 and the driven wheel 58, the screw rod 52 can rotate forwardly in the opposite direction to the rotation direction of the aggregate shell 31. When the screw rod 52 rotates forwardly, the mixed feed can be transported to the upper part of the inner cavity of the feed barrel 51 through the feed hole 54 and discharged through the discharge hole 55. When the screw rod 52 rotates, it drives the dividing rod 56 to rotate circumferentially, which can divide the mixed feed in the feed barrel 51 and the discharge hole 55, so as to avoid the mixed feed from forming long strips when it is discharged and is inconvenient for frogs to eat. When the mixed feed moves in the feed barrel 51, the excess water carried by the mixed feed can be discharged through the water filter hole. The raised annular enclosure 81 can enclose the mixed feed discharged from the discharge hole 55.When the aggregate shell 31 rotates in the opposite direction to drive the sleeve 38 upward, the guide shell 33 drives the blocking block 35 to combine with the feed channel 34 under the elastic force of the spring compression rod 310, and the blocking block 35 pushes the support rod 73 to drive the sealing plate 72 to move upward, so that the water in the aquatic vegetable area can enter the feeding trough 6 through the water inlet channel 71. As the sleeve 38 continues to move upward and contacts the rotating rod 83, it can push the rotating rod 83 to rotate. When the rotating rod 83 rotates, it can drive the linkage rod 82 to drive the annular enclosure 81 to move downward and embed into the annular groove through the action of the pin shell. After that, the mixed feed can slide to the water surface in the feeding trough 6 and float for the frogs to eat.
