Description

Technical Field

[0001] This invention belongs to the field of circular farming technology, specifically an ecological circular farming method for vegetables, frogs, rice, and black soldier fly larvae. Background Technology

[0002] With the continuous advancement of cultivation techniques, the growing season for vegetables has become shorter, and pests and diseases have become more severe. Most vegetables now require multiple applications of pesticides before they can mature and be marketed. Currently, pest control in the production of pollution-free vegetables mainly utilizes methods such as light trapping, drip irrigation, and spraying with low-residue biological pesticides. Natural methods can also be utilized, such as using frogs to kill pests, which simultaneously achieves the purposes of weeding, loosening the soil, and fertilizing.

[0003] Currently, frog farming in vegetable fields is relatively rare. Most ecological farming is integrated rice-frog farming, which aims to achieve a double harvest of rice and frogs. This involves building frog ponds and feeding platforms in rice fields and using rice-tobacco rotation to achieve a double harvest of rice and frogs.

[0004] In the prior art, a Chinese patent discloses a feed feeding device for rice-frog ecological farming (publication number: CN218126422U). Its main structure includes a chassis, a guide rod, a feeding bin, a feeding pipe, a feeding tray, a spring, a glass plate, a dispersing 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 feeding bin, the bottom of the feeding bin is penetrated by the feeding pipe, the upper part of the guide rod is slidably fitted with a feeding tray located directly below the feeding bin, the feeding tray is connected to the chassis by a spring, the front and rear sides of the feeding bin are embedded with glass plates for observing the remaining feed, and the feeding bin is provided with a dispersing component for dispersing the feed and a blocking component for blocking the feed.

[0005] In practical use, the aforementioned patent involves feeding rice-frogs by having feed flow from the feeding hopper into the feeding frame, which then flows into three feeding pipes. The feed is then discharged in a limited amount onto the feeding tray via a limiting pipe, thus feeding the rice-frogs evenly and slowly. However, there are still some drawbacks in practical use: In the ecological farming of frogs, they can be fed with traditional feed and small insects. When small insects are used as feed, some insects may be crushed or destroyed during transport. These destroyed insects are not easily noticed by the frogs and are therefore less likely to be eaten. In the case of the aforementioned patent, when feeding small insects to frogs, the destroyed insects that are not eaten by the frogs are prone to spoilage and harm the frogs. Summary of the Invention

[0029] Beneficial effects

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

[0031] 1. This invention, through the coordinated design of a feeding platform and a recycling mechanism, allows operators to control the drive mechanism via an external control system. The drive mechanism rotates the collection shell in the forward direction, which in turn drives the sleeve to move downward. The sleeve pushes the guide shell downward, causing the sealing block to separate from the discharge channel. Simultaneously, the rotation of the collection shell causes the cleaning rod to rotate circumferentially to clean up the inactivated black soldier fly larvae that have not been eaten by the frogs in the feeding trough. The inactivated black soldier fly larvae fall into the guide shell through the discharge channel and the guide hole. As the guide shell continues to move downward until the discharge port coincides with the interface, the inactivated black soldier fly larvae in the guide shell enter the collection shell through the interface for collection. This allows for the recycling of inactivated black soldier fly larvae, improving the safety of feeding frogs and solving the problem in existing technologies where inactivated insects that are not eaten by frogs easily decompose and harm the frogs.

[0032] 2. This invention, through the coordinated design of the collection shell, drive mechanism, and mixing and feeding mechanism, allows the operator to control the drive motor to rotate the collection shell in the forward direction via an external control system. Simultaneously, the external control system controls the solenoid valve to open via a sensor, allowing the feed inside the collection shell to fall. When the external control system controls the drive motor to rotate the collection shell in the reverse direction, the external control system controls the solenoid valve to close via a sensor, stopping the feed from falling. Simultaneously, when the drive motor drives the collection shell to rotate in the reverse direction, the action of the coupling wheel and driven wheel causes the screw rod to rotate in the opposite direction to the collection shell. When the screw rod rotates in the forward direction, the mixed feed is conveyed through the feed inlet to the upper part of the inner cavity of the conveying cylinder and discharged through the discharge outlet, falling back into the feeding trough. Furthermore, the rotation of the screw rod drives the dividing rod to rotate circumferentially, dividing the mixed feed in the conveying cylinder and discharge outlet, preventing the mixed feed from forming long strips that are difficult for frogs to eat, thus improving resource utilization, reducing the cost of feeding frogs, and avoiding resource waste.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1 to 10 As shown, this invention provides an ecological circular farming method for vegetables, frogs, rice, and black soldier fly larvae. The specific steps of the circular farming method are as follows:

[0046] S1: Vegetable cultivation is divided into aquatic vegetable area and conventional vegetable area. The breeding base is located in a tropical and subtropical monsoon climate zone, moderated by the marine climate year-round. Winters are mild and summers are not too hot, with an average annual temperature of 22.7℃~23.5℃. Frogs have almost no hibernation period throughout the year and can lay eggs as long as there is water. It takes about 3-4 months from egg-laying to froglets, and about 3-4 months from froglets to adults, which is about the same time as a vegetable crop. Aquatic vegetables mainly include lotus root, water celery, and arrowhead, with a small amount of algae added. The conventional vegetable area mainly rotates legumes, eggplants, root vegetables, and cucurbits, and also grows one crop of rice each year.

[0047] S2: Set up the aquatic vegetable area as the frog breeding and hatching area, and set up the conventional vegetable area as the frog breeding area. Frogs can be used to control pests in the vegetable planting area. The number of frogs released in the breeding area depends on the amount needed to achieve the effect of pest control during the vegetable planting process. The number of frogs released per acre is 2,000-3,000. In the aquatic vegetable area, the frogs are released at a male-to-female ratio of 1:1, with 30 pairs of breeding frogs released per acre.

[0048] S3: A 200-mu (approximately 33 acres) 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: Set up feeding platform 1 in the aquatic vegetable area. Operators place the produced black soldier fly larvae on feeding platform 1 to feed the frogs.

[0050] S5: Vegetables are planted in the conventional vegetable area from January to April each year, rice is planted from May to August, and vegetables are planted from September to December to achieve crop rotation. After the frogs in the conventional vegetable area mature, they are captured and placed in the aquatic vegetable area to breed and fatten them. Then, the juvenile frogs in the aquatic vegetable area are placed in the conventional vegetable area for breeding to achieve circular farming.

[0051] The operational procedures in step S4 of the above-mentioned circular farming method need to be completed by the feeding station 1, wherein:

[0052] The feeding platform 1 includes a placement shell 2, a recycling mechanism 3 disposed inside the placement shell 2 for cleaning up inactive black soldier fly larvae, a drive mechanism 4 disposed in the lower part of the inner cavity of the placement shell 2 for driving the recycling mechanism 3, and a mixing and feeding mechanism 5 disposed on the recycling mechanism 3.

[0053] The upper surface of the housing 2 is provided with a feeding trough 6, and the inner side wall of the feeding trough 6 is provided with a water inlet mechanism 7.

[0054] The recycling mechanism 3 includes a collection shell 31 that is movably mounted on the top surface of the inner cavity of the placement shell 2 via a bearing, a mating interface 32 that is circumferentially equidistantly opened on the lower part of the outer surface of the collection shell 31, a guide shell 33 that is movably sleeved on the outer surface of the collection shell 31, a discharge channel 34 that is circumferentially equidistantly opened on the bottom surface of the inner cavity of the feeding trough 6, a sealing block 35 that is fixed on the upper surface of the guide shell 33 and adapted to the discharge channel 34, a guide hole 36 that is opened on the upper surface of the guide shell 33 between two adjacent sealing blocks 35, a discharge port 37 that is circumferentially opened on the lower part of the inner ring of the guide shell 33, and a sleeve 38 that is threaded on the outer surface of the collection shell 31 and located above the guide shell 33.

[0055] The top surface of the collection shell 31 extends to the top of the feeding trough 6, and the top surface of the collection shell 31 is conical. Cleaning rods 39 are fixedly installed circumferentially at equal intervals on the upper part of the outer surface of the collection shell 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 symmetrically and vertically fixedly installed on the bottom surface of the inner cavity of the placement shell 2. The output end of the spring compression rods 310 is fixedly connected to the bottom surface of the guide shell 33. Two vertical rods are symmetrically and vertically fixedly installed on the top surface of the inner cavity of the placement shell 2. The vertical rods pass through the sleeve 38 and the guide shell 33. The bottom surface of the sleeve 38 is movably connected to the upper surface of the guide shell 33.

[0056] In use, the feeding platform 1 is placed in the water of the aquatic vegetable area, with the upper surface of the placement shell 2 slightly above the water surface. Black soldier fly larvae are placed in the feeding trough 6, and water from the aquatic vegetable area is introduced into the feeding trough 6 through the water inlet mechanism 7. Surviving black soldier fly larvae float on the surface of the water in the feeding trough 6, while inactive black soldier fly larvae sink to the bottom (if black soldier fly larvae that have not been eaten by frogs are inactive, their density will increase due to the increased water content, exceeding the buoyancy threshold and naturally sinking to the bottom of the feeding trough 6. Since frogs' visual system is sensitive to moving objects, larvae that sink to the bottom are difficult for frogs to detect due to their lack of movement, thus preventing inactive larvae from being eaten by frogs). This makes it easier for frogs to eat the surviving black soldier fly larvae. After the frogs have finished eating, the operator controls the drive mechanism 4 through the external control system. The drive mechanism 4 drives the collection shell 31 to rotate forward, and when the collection shell 31 rotates forward, it drives the sleeve 38 to move... As the sleeve 38 moves downwards, it pushes the guide shell 33 downwards. When the guide shell 33 moves downwards, it causes the sealing block 35 to separate from the discharge channel 34. Simultaneously, the rotating collection shell 31 causes the cleaning rod 39 to rotate circumferentially to clean the inactive black soldier fly larvae in the feeding trough 6 that have not been eaten by the frogs. (To prevent the inactive larvae from spoiling in the feeding trough 6 and harming the frogs, the inactive black soldier fly larvae in the feeding trough 6 are cleaned.) The process involves feeding inactivated black soldier fly larvae through the feeding channel 34 and the feeding hole 36 into the feeding shell 33. As the feeding shell 33 continues to move downwards until the discharge port 37 coincides with the docking port 32, the inactivated black soldier fly larvae in the feeding shell 33 enter the collection shell 31 through the docking port 32 for collection. This process enables the recovery of inactivated black soldier fly larvae, improves the safety of feeding frogs, and avoids the problem of inactivated insects that are not eaten by frogs easily deteriorating and harming the frogs.

[0057] It is worth noting that when the collection shell 31 rotates in the forward direction to drive the mixing and feeding mechanism 5, the mixing and feeding mechanism 5 can sprinkle traditional feed into the bottom of the inner cavity of the collection 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. Moreover, if the inactivated black soldier fly larvae are left to stand for a long time, they are prone to deterioration and the production of harmful substances. Therefore, they are used rationally before they deteriorate. The black soldier fly larvae are reused by mixing them with feed and feeding them to the frogs). Then, the drive mechanism 4 is controlled to drive the collection shell 31 to rotate in the reverse direction. When the collection shell 31 rotates in the reverse direction, it can drive the mixing and feeding mechanism 5 to put the feed mixed with inactivated black soldier fly larvae in the inner cavity of the collection shell 31 back into the feeding trough 6 for the frogs to eat. This improves the resource utilization rate, reduces the cost of feeding the frogs, and avoids the problem of resource waste.

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

[0059] In use, the operator can control the rotation direction of the drive motor 42 through the external control system. When the drive motor 42 is running, it causes the drive wheel 43 to rotate. The rotation of the drive wheel 43 drives the annular plate 41 to rotate, and the rotation of the annular plate 41 can drive the collection shell 31 to rotate.

[0060] like Figure 9 As shown, the water inlet mechanism 7 includes a water inlet channel 71 circumferentially equidistantly opened on the inner side wall of the feeding trough 6, a sealing plate 72 that moves vertically in the inner cavity of the water inlet channel 71, a support rod 73 that is vertically fixed to the bottom surface of the sealing plate 72, and a compression spring 74 that is movably sleeved on the support rod 73.

[0061] 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 guide shell 33. 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] When in use, after the feed 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. The sealing plate 72 can seal the water inlet channel 71, 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 and feeding mechanism 5 includes a conveying cylinder 51 vertically fixed to the bottom surface of the inner cavity of the collecting shell 31, a spiral rod 52 movably installed in the inner cavity of the conveying cylinder 51 via bearings, a storage shell 53 fixedly sleeved in the middle of the outer surface of the conveying cylinder 51, a feed hole 54 circumferentially and equidistantly opened at the lower part of the outer surface of the conveying cylinder 51, a discharge hole 55 circumferentially and equidistantly opened at the upper part of the outer surface of the conveying cylinder 51, a dividing rod 56 symmetrically fixedly installed on the left and right sides of the upper part of the spiral rod 52, and a baffle mechanism 8 provided on the upper surface of the collecting shell 31.

[0064] Among them, the bottom surface of the placement shell 2 is rotatably mounted with a docking wheel 57 via a rotating shaft. The outer ring of the docking wheel 57 is movably connected to the inner ring of the annular plate 41. The bottom end of the spiral rod 52 penetrates to the bottom of the collection shell 31. The lower part of the spiral rod 52 is fixedly fitted with a driven wheel 58. The outer ring of the driven wheel 58 is movably connected to the outer ring of the docking wheel 57. The outer surface of the conveying cylinder 51 is provided with filter holes circumferentially at equal intervals below the storage shell 53. A set of solenoid valves 9 for controlling feed discharge is provided circumferentially on the bottom surface of the storage shell 53. A sensor 10 with built-in power supply for controlling the opening and closing of the solenoid valves 9 is fixedly installed on one side of the bottom surface of the storage shell 53. The sensor 10 and the drive motor 42 are both connected to an external control system. A feeding port is provided circumferentially on the top surface of the storage shell 53. A set of feeding channels is provided circumferentially at equal intervals on the upper surface of the collection shell 31. A cover plate is provided in the inner cavity of the feeding channel.

[0065] In use, when the operator controls the drive motor 42 to rotate the collection shell 31 in the forward direction via the external control system, the external control system synchronously controls the solenoid valve 9 to open via the sensor 10, allowing the feed in the storage shell 53 to fall. When the external control system controls the drive motor 42 to rotate the collection shell 31 in the reverse direction, the external control system synchronously controls the solenoid valve 9 to close via the sensor 10, stopping the feed from falling into the storage shell 53. At the same time, when the drive motor 42 drives the collection shell 31 to rotate in the reverse direction, under the action of the coupling wheel 57 and the driven wheel 58, the spiral... The rotation of the screw rod 52 is opposite to the rotation of the collection shell 31. When the screw rod 52 rotates in the forward direction, the mixed feed can be conveyed through the feed inlet 54 to the upper part of the inner cavity of the feed cylinder 51 and discharged through the discharge outlet 55 back into the feeding trough 6. Furthermore, the rotation of the screw rod 52 drives the dividing rod 56 to rotate circumferentially, which can divide the mixed feed in the feed cylinder 51 and the discharge outlet 55, preventing the mixed feed from forming long strips that are difficult for frogs to eat when discharged. (The feed is a processed floating feed with a porous internal structure, low density, and the ability to float on the water surface.) The floating feed constitutes a larger proportion of the black soldier fly larvae in the feed. After being divided by the dividing rod 56, the mixed feed is cut into very small pieces. The smaller feed particles have a smaller volume, which reduces the weight of the feed particles. At the same time, their surface area is relatively increased, allowing for more sufficient contact with water and a more significant buoyancy effect in the water. As a result, the mixture can float and avoid sinking to the bottom. On the other hand, when frogs are hunting, it is easier for them to find and ingest these floating small feed particles, improving the frogs' feeding efficiency of the mixed feed and ensuring the effective utilization of the feed. Furthermore, the mixed feed is contained within the feed delivery cylinder 51. During exercise, the filter holes facilitate the drainage of excess water carried by the mixed feed (because the mixed feed contains inactivated black soldier fly larvae and other components, it often carries excess water, which increases the overall weight of the mixed feed. Therefore, draining the excess water through the filter holes reduces the water content of the mixed feed, making the overall weight of the mixed feed lighter and reducing the degree of adhesion. In the water of the feeding trough 6, the feed particles can be more fully dispersed, increasing the contact area with water. The mixed feed can then easily float in the feeding trough 6, effectively avoiding the phenomenon of sinking to the bottom and ensuring that the frogs can feed).

[0066] As shown in 10, the material blocking mechanism 8 includes an annular groove opened on the upper surface of the material collection shell 31, an annular surrounding plate 81 that moves up and down in the inner cavity of the annular groove, two connecting rods 82 that are symmetrically and vertically fixed on the bottom surface of the annular surrounding plate 81, and a rotating rod 83 that is rotatably installed in the material collection shell 31 via a rotating shaft.

[0067] One end of the rotating rod 83 extends through the inner cavity of the collection 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. A pin is fixedly installed at the bottom end of the connecting rod 82, and the other end of the rotating rod 83 is movably connected to the inner cavity of the pin. A tension spring 84 is movably sleeved on the connecting rod 82, and the upper and lower ends of the tension spring 84 are fixedly connected to the top surface of the inner cavity of the collection shell 31 and the top surface of the pin, respectively.

[0068] In use, under the tension of the tension spring 84, the annular enclosure 81 can be driven to move upward through the linkage rod 82 to block the mixed feed discharged from the discharge hole 55. When the collecting shell 31 rotates in the opposite direction, the sleeve 38 moves upward. Under the elastic force of the spring compression rod 310, the guide shell 33 drives the sealing block 35 to engage with the discharge channel 34. 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, through the action of the pin shell, it can drive the linkage rod 82 to move the annular enclosure 81 downward and embed it into the annular groove. Then the mixed feed can slide into the feeding trough 6 for the frogs to eat.

[0069] Working principle and usage process of this invention:

[0070] In use, the feeding platform 1 is first placed in the water of the aquatic vegetable area, with the upper surface of the placement shell 2 slightly above the water surface. This prevents the black soldier fly larvae in the feeding trough 6 from escaping if the water in the aquatic vegetable area submerges the placement shell 2. Simultaneously, frogs can easily climb onto the placement shell 2 to feed. Water from the aquatic vegetable area enters the feeding trough 6 through the water inlet channel 71. Surviving black soldier fly larvae float on the surface of the water in the feeding trough 6, while inactive larvae sink to the bottom, making it easier for frogs to eat the surviving larvae. Placing the black soldier fly larvae in the feeding trough 6 facilitates frog consumption. After the frogs have finished feeding, the operator controls the drive motor 42 to rotate forward via the external control system. The rotation of the drive motor 42 drives the drive wheel 43 and... The annular plate 41 drives the collecting shell 31 to rotate forward. When the collecting shell 31 rotates forward, it drives the sleeve 38 to move downward. The sleeve 38 can push the guide shell 33 to move downward. When the guide shell 33 moves downward, it causes the sealing block 35 to separate from the discharge channel 34. At the same time, when the collecting shell 31 rotates, it causes the cleaning rod 39 to rotate circumferentially to clean the inactive black soldier fly larvae in the feeding trough 6 that have not been eaten by the frogs. The inactive black soldier fly larvae and the water in the feeding trough 6 fall into the guide shell 33 through the discharge channel 34 and the guide hole 36. 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. The sealing plate 72 can seal the water inlet channel 71 and prevent water from the aquatic vegetable area from entering the water inlet channel 71. 1. When the feed enters the feeding trough 6, the sleeve 38 moves down and, under the tension of the tension spring 84, drives the annular enclosure 81 to rise via the linkage rod 82. When the guide shell 33 continues to move down so that the discharge port 37 coincides with the interface 32, the inactivated black soldier fly larvae in the guide shell 33 enter the collection shell 31 through the interface 32 for collection. When the operator controls the drive motor 42 to rotate the collection shell 31 in the forward direction via the external control system, the external control system synchronously controls the solenoid valve 9 to open via the sensor 10, allowing the feed in the storage shell 53 to fall. When the external control system controls the drive motor 42 to rotate the collection shell 31 in the reverse direction, the external control system synchronously controls the solenoid valve 9 to close via the sensor 10, stopping the feed in the storage shell 53 from falling. When the drive motor 42 drives the collection shell 31 to rotate in the opposite direction, under the action of the connecting wheel 57 and the driven wheel 58, the screw rod 52 can rotate in the opposite direction to the rotation of the collection shell 31. When the screw rod 52 rotates in the forward direction, the mixed feed can be conveyed through the feed hole 54 to the upper part of the inner cavity of the conveying cylinder 51 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 conveying cylinder 51 and the discharge hole 55, so as to prevent the mixed feed from forming long strips that are not easy for frogs to eat when discharged. When the mixed feed moves in the conveying cylinder 51, the excess water carried by the mixed feed can be discharged through the water filter hole. The raised annular plate 81 can contain the mixed feed discharged from the discharge hole 55.When the feed collection shell 31 rotates in the reverse direction, driving the sleeve 38 to move upward, the spring compression rod 310 causes the guide shell 33 to engage with the sealing block 35 and the discharge channel 34. The sealing block 35 then pushes the support rod 73 to move the sealing plate 72 upward, allowing water from the aquatic vegetable area to 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 drives the rotating rod 83 to rotate. When the rotating rod 83 rotates, the pin housing drives the connecting rod 82 to move the annular surrounding plate 81 downward and embed it into the annular groove. Afterward, the mixed feed slides onto the water surface in the feeding trough 6 and floats for the frogs to eat.
