Description

Technical Field

[0001] The invention belongs to the technical field of rice-shrimp breeding equipment, and in particular relates to a rice-shrimp feeding system and a rice-Macrobrachium rosenbergii symbiotic breeding method. Background Art

[0002] Macrobrachium rosenbergii is a common aquaculture species. In the past two years, the total production of Macrobrachium rosenbergii in my country is about 160,000 tons, and the total production in Zhejiang Province is 30,000 tons, accounting for 18% of the national total production. Because Macrobrachium rosenbergii has a high economic value, the average net profit per mu of Macrobrachium rosenbergii in Zhejiang Province is 6,000 yuan, which is higher than other common shrimp farming. Therefore, it is expected that the scale of Macrobrachium rosenbergii farming will continue to expand in recent years. However, due to the limitation of the water area of ​​the breeding area, many farmers use rice fields to breed Macrobrachium rosenbergii; in order to ensure food security, when breeding Macrobrachium rosenbergii in rice fields, the grain yield per mu of rice fields must be guaranteed, and rice planting cannot be abandoned simply for the pursuit of high yield of Macrobrachium rosenbergii.

[0003] Macrobrachium rosenbergii cannot crawl around freely in rice fields like crayfish, and its crawling ability is relatively weak. The activity range of Macrobrachium rosenbergii is often small. When feeding Macrobrachium rosenbergii in rice fields, it cannot be fed by boat like in ponds. It can generally only be fed on the ridges of fields. Macrobrachium rosenbergii in the middle of rice fields often cannot eat the feed, which affects its growth rate. When it is taken out of the pond, it is smaller in size, resulting in a lower selling price. Summary of the invention

DETAILED DESCRIPTION

[0042] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0043] See also Figures 1 to 6 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0044] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0045] See also Figure 1The present invention provides a rice-shrimp feeding system, comprising a projection module 1, a pellet module 2 and a feed pellet 7, wherein the projection module 1 comprises a barrel 11 and a firing assembly 12, wherein a barrel hole 13 is provided on the barrel 11 along its axial direction, the pellet module 2 drives the feed pellet 7 to enter the tail end of the barrel hole 13, and the firing assembly 12 drives the feed pellet 7 to be ejected from the barrel hole 13, wherein the outer skin of the feed pellet 7 is made of water-soluble materials such as gelatin of animal origin or hydroxypropyl methylcellulose (HPMC) of plant origin, and feed pellets of the same size as millet grains are wrapped under the outer skin. After the feed pellet 7 is projected into the rice field, as the outer skin dissolves, the feed pellets in the outer skin are scattered into the water, and the Macrobrachium rosenbergii can eat them, thereby ensuring the normal growth of the Macrobrachium rosenbergii, and the projection module 1 can be held by a staff member or carried forward by a walking mechanism, and the specific structures of the projection module 1 and the pellet module 2 as well as the different situations of hand-held and mechanism-carried will be introduced below.

[0046] For this example, please refer to Figure 1 and Figure 2 The firing assembly 12 includes an air tank 121, a pressurizing component 122, a one-way valve 123, a first automatic valve 124 and an air pressure sensor. The pressurizing component 122 is connected to one end of the air tank 121 through the one-way valve 123, and the other end of the air tank 121 is connected to the bottom end of the barrel hole 13 through the first automatic valve 124. The air pressure sensor is arranged on the first automatic valve 124. When feeding is required, the pelleting module 2 first puts the feed pellets 7 on the bottom end of the barrel 11 to ensure that the body The bottom end of the tube hole 13 and the connecting part of the gas tank 121 are sealed, and the pressurizing component 122 fills the gas into the gas tank 121 through the one-way valve 123. As the gas in the gas tank 121 is filled, the gas pressure in the gas tank 121 gradually increases. After reaching the set value, the air pressure sensor senses and controls the first automatic valve 124 to open, and the gas in the gas tank 121 instantly rushes into the barrel 11, driving the feed pellet 7 to be ejected from the barrel 11. The projection distance of the feed pellet 7 is controlled by controlling the size of the set value.

[0047] After the feed pellets 7 are projected, the air pressure in the air storage tank 121 decreases, and the air pressure sensor controls the first automatic valve 124 to close, and this process repeats to achieve continuous projection of the feed pellets 7;

[0048] If the staff holds the projection mechanism, the boosting component 122 uses a one-handed air pump. If the projection mechanism is carried by a walking mechanism, the boosting component 122 uses a turbocharger. The specific structures of the one-handed air pump and the turbocharger are not described in detail here.

[0049] For this example, please refer to Figure 3In addition to the structure described above, the firing assembly 12 can also be equipped with a firing column 125. The piston is pushed to move quickly by high-pressure gas. One end of the piston is connected to one end of the firing column 125, and the other end of the firing column 125 moves between the rear part of the barrel hole 13 and the outside of the barrel 11. The rapid movement of the piston drives the firing column 125 to quickly penetrate into the bottom end of the barrel 11 from the outside of the barrel 11, and push the feed pill 7 out of the barrel 11. After the feed pill 7 is projected, the gas in the piston chamber 126 is extracted using a micro-exhaust device 127, and the piston withdraws from the bottom end of the barrel hole 13 with the firing column 125. The structure of the firing assembly 12 has been shown in the figure. Compared with the structure described above, this structure is more complicated and more troublesome to maintain, but the airtightness requirements for the barrel 11 are not very high. The specific connection composition method of this structure will not be repeated here.

[0050] For this example, please refer to Figure 4 and Figure 6 The pill loading module 2 includes a pill inlet 21, a pill inlet door 22 and a first power member 23. The pill inlet 21 is opened on the side wall of the bottom of the barrel 11. The feed pill 7 enters the bottom end of the barrel 11 from the pill inlet 21. At the same time, the first power member 23 drives the pill inlet door 22 to close the pill inlet 21 to ensure that when the high-pressure gas rushes into the barrel 11, it can fully act on the feed pill 7 along the axial direction of the barrel 11 and push the feed pill 7 out. When it is necessary to load the feed pill 7 on the barrel 11, the first power member 23 drives the pill inlet door 22 to open the pill inlet 21.

[0051] For this example, please refer to Figure 4 and Figure 6 A door slot 24 is provided at the rear of the barrel 11, and the shot inlet door 22 and the door slot 24 are slidably matched. A pull handle 25 is provided on the shot inlet door 22. The first power member 23 is a telescopic rod, and the telescopic rod is installed on the side wall of the barrel 11. The telescopic rod includes a fixed end and a telescopic end, and the telescopic end is fixedly connected to the pull handle 25. The length direction of the door slot 24 and the telescopic direction of the telescopic rod are both along the axial direction of the barrel hole 13. The telescopic rod is a micro-electric telescopic rod. The purpose of designing the pull handle 25 is that when the staff holds the projection mechanism by hand and the micro-electric telescopic rod is not installed, the staff can pull the pull handle 25 by hand to control the movement of the shot inlet door 22 in the door slot 24.

[0052] For this example, please refer to Figure 6, we introduce the situation when the walking mechanism is used to carry the projection module 1. A rice-shrimp feeding system also includes a working platform 4, and the upper pill module 2 also includes a pill storage barrel 26, a pill pushing rod 27, a second power member 28 and a pill supporting plate 29. The bottom of the pill storage barrel 26 is installed on the working platform 4, and a pill outlet 261 is opened on the upper part of the pill storage barrel 26. The pill outlet 261 is connected to the pill inlet 21. The pill supporting plate 29 is slidably installed inside the pill storage barrel 26. Feed pills 7 are placed on the pill supporting plate 29. The diameter of the feed pills 7 is greater than half of the inner diameter of the pill storage barrel 26 and smaller than the inner diameter of the pill storage barrel 26. In this way, the feed pills 7 can be placed vertically in the pill storage barrel 26 one by one. The second power member 28 uses a rodless cylinder, which is installed on the outer wall of the pill storage barrel 26 and drives the pill supporting plate 29 to move between the bottom and the top of the pill storage barrel 26. The pill pushing rod 27 uses a small hydraulic cylinder;

[0053] When it is necessary to provide feed pellets 7 to the barrel 11, the rodless cylinder drives the pellet support plate 29 to rise, and when a feed pellet 7 rises to the pellet storage port, the telescopic end of the small hydraulic cylinder extends into the pellet outlet 261 to push a feed pellet 7 into the pellet inlet 21 of the barrel 11;

[0054] For this example, please refer to Figure 4 and Figure 5 The pill upper module 2 further includes a pill storage tray 30 and a rotating power component 31. The pill storage tray 30 is mounted on the working platform 4. There are multiple pill storage barrels 26. Multiple pill storage barrels 26 are fixedly mounted on the pill storage tray 30 along the circumference of the pill storage tray 30. The rotating power component 31 drives the pill storage tray 30 to rotate. Multiple pill storage barrels 26 rotate with the rotation of the pill storage tray 30. The pill outlets 261 on different pill storage barrels 26 are sequentially connected to the pill inlet The first and second power members 28 drive the pill-supporting plate 29 to descend to the bottom of the pill barrel 26, and then fill the pill barrel 26 with feed pills 7 again.

[0055] For this example, please refer to Figure 5The rotating power component 31 includes a rotating power piece 311, a driving gear 312, a driven gear 313 and an inner gear ring 314. A through hole is opened in the center of the pill storage tray 30. The outer wall of the inner gear ring 314 fits and is fixedly connected to the inner wall of the through hole. There are three driven gears 313 and they are meshed with the inner gear ring 314 at equal intervals along the circumference. The driving gear 312 meshes with the three driven gears 313 at the same time. The rotating power piece 311 drives the driving gear 312 to rotate. The rotating power piece 311 uses a servo motor. The power end of the servo motor is connected to the driving gear 312 through a coupling or a reducer. The three driven gears 313 are rotatably connected to the working platform 4 through a rotating shaft, and the pill storage tray 30 is rotatably installed on the working platform 4.

[0056] For this example, please refer to Figure 5 The rotating power member 311 also includes rollers 315, and there are at least three rollers 315. The rollers 315 are rollingly installed between the working platform 4 and the lower surface of the pill storage tray 30. The design of three rollers 315 increases the stability of the pill storage tray 30 during rotation.

[0057] For this example, please refer to Figure 1 , also includes a crawler walking module 5 and a control module 6, the control module 6, the projection module 1 and the pelleting module 2 are all installed on the crawler walking module 5, because if the rice-shrimp feeding system described in this article is not held by a person, but is carried by a walking mechanism, it is necessary to walk on the ridge in the middle of the rice field, so a crawler walking mechanism is selected, which does not need to be held by a person, and the intelligence level of the entire system needs to be increased, so the control module 6 is selected to control the entire system, and the specific control circuit is not described in detail here.

[0058] See also Figure 1 A rice-shrimp symbiotic breeding method based on the rice-shrimp feeding system described above comprises the following steps:

[0059] Prepare the rice field: select a rice field with an area of ​​5-8 mu; set a ridge with a width greater than that of the crawler walking module 5 in the rice field, dig a ditch around the rice field after rice harvesting, the ditch depth is 80-100 cm, the ditch area is 10% of the rice field area, and surround the inner side of the ditch with a nylon net 2-3 meters inward; set inlets and drainage outlets around the rice field, and set nets at the inlets and drainage outlets;

[0060] Building a ring ditch greenhouse: Building a greenhouse in the ring ditch, the area of ​​the greenhouse accounts for 1 / 2-2 / 3 of the area of ​​the ring ditch, and isolating the water body in the greenhouse from the water body outside the greenhouse with an isolator, in order to facilitate the subsequent cultivation of Macrobrachium rosenbergii fry (larvae of Macrobrachium rosenbergii) in the water body in the greenhouse;

[0061] Disinfection and water diversion: disinfecting the rice field and the ring ditch to prevent the adverse effects of fungi on the subsequently cultured Macrobrachium rosenbergii, and diverting water thereto;

[0062] Planting grass: Planting aquatic grass in the ring ditch in late March. The aquatic grass is planted in a dotted distribution, and the planting area is 20% of the ring ditch area. The aquatic grass includes high-temperature resistant aquatic grass and low-temperature resistant aquatic grass. The planting ratio of high-temperature resistant aquatic grass to low-temperature resistant aquatic grass is 1:1, so as to provide certain food and shelter for the larvae of Macrobrachium rosenbergii cultured later;

[0063] Release of Macrobrachium rosenbergii fry: 5-7 days before release of fry, adjust the water level in the greenhouse to 60-70 cm and fertilize the water; after the water temperature in the greenhouse reaches 15°C, release Macrobrachium rosenbergii fry into the water in the greenhouse, and the release density of Macrobrachium rosenbergii fry is 3000-4000 per square meter;

[0064] Replace the water: after the shrimp fry are released, the water in the greenhouse is replaced every 1-2 days, and 3 days after the shrimp fry are released, the shrimp starter feed is fed to the water in the greenhouse;

[0065] Removing the greenhouse: One month after the release of Macrobrachium rosenbergii fry, the greenhouse and the isolation are removed, the water in the greenhouse is connected to the water in the ring ditch, and the grown shrimp fry swim from the water in the greenhouse to other places in the ring ditch for further growth. The fry are cultured in the ring ditch for about one month;

[0066] Planting rice: applying basal fertilizer in the rice field surrounded by the nylon net, and sowing rice seeds or transplanting rice seedlings after an interval of 7-10 days. If rice seeds are directly sown in the rice field, it is generally carried out in late April, and if rice seedlings are transplanted, it is carried out in mid-May;

[0067] Rice and Macrobrachium rosenbergii cultivation docking: After Macrobrachium rosenbergii has been cultivated in the ring ditch for one month, the water level of the rice field is adjusted to above 20 cm, and the nylon net is removed. Macrobrachium rosenbergii swims freely in the ring ditch and the rice field. As Macrobrachium rosenbergii grows, they need a larger area of ​​water. Therefore, the nylon net needs to be removed at this time to provide a larger area for the growing Macrobrachium rosenbergii. Then, as the rice grows, the water level in the rice field is raised until the water level in the rice field is kept at 40-50 cm in the early stage of rice jointing, so as to achieve rice and Macrobrachium rosenbergii cultivation docking;

[0068] Feeding after planting and breeding docking: the crawler walking module carries the control module 6, the projection module 1 and the pelleting module 2 to walk on the ridge, the control module 6 controls the pelleting module 2 to provide the body tube 11 with feed pellets 7, the control module 6 controls the projection module 1 to project the feed pellets 7 from the body tube 11 to the middle of the rice field, and controls the projection distance of the feed pellets 7 by controlling the pressure of the gas in the gas storage tank 121, so as to ensure that the Macrobrachium rosenbergii at all positions in the rice field can eat the feed;

[0069] Breeding management after planting and breeding: replace the water in the rice field once every 7 days, apply quicklime once every 15 days, and the amount of quicklime is 100kg / mu to ensure the hygiene of the water body, thereby ensuring that the Macrobrachium rosenbergii can grow healthily and avoid the occurrence of infectious diseases;

[0070] Capturing Macrobrachium rosenbergii: Adjust the water level in the rice fields to 20 cm from late July to early August to capture Macrobrachium rosenbergii;

[0071] Sunning the rice fields: After the capture of Macrobrachium rosenbergii is completed and the rice is in the jointing and heading stage, the rice fields are sunned. After the sunning is completed, the water level of the rice fields is adjusted to 30 cm;

[0072] Harvesting rice: Rice is harvested in late September when the rice is fully ripe.

[0073] In summary, a rice-shrimp feeding system and a rice-Macrobrachium rosenbergii symbiotic breeding method of the present invention projects the feed pellet 7 from the body tube 11 to the middle of the rice field through the guidance of the body tube 11 and the firing force of the firing assembly 12, and adjusts the firing force of the firing assembly 12 to achieve the function of controlling the projection distance of the feed pellet 7, thereby solving the problem that the feeding distance of the feeding equipment in the prior art is short, resulting in the Macrobrachium rosenbergii in the middle of the rice field not being able to eat the feed; and then through the design of the air storage tank 121, the boosting component 122, the one-way valve 123, the first automatic valve 124 and the air pressure sensor, the air storage tank 121 is inflated through the boosting component 122, and due to the action of the one-way valve 123, the air The body will only rush into the gas tank 121 from one end of the boost component 122. After the air pressure in the gas tank 121 reaches a certain value, the air pressure sensor senses and controls the first automatic valve 124 to open. The high-pressure gas in the gas tank 121 instantly rushes into the barrel 11, pushing the feed pellets 7 out of the barrel 11, so as to achieve the purpose of projecting the feed pellets 7 over a long distance. The structure of the entire firing assembly 12 is simple and easy to maintain. At the same time, through a rice-Macrobrachium rosenbergii symbiotic breeding method, Macrobrachium rosenbergii is cultivated in rice fields under the condition of normal rice planting, which not only ensures food security but also increases farmers' income, increases economic benefits, and increases the regional gross national product. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
