Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to feeding equipment for seedling cultivation and a feeding method for crayfish cultivation. Background Art

[0002] The suitable temperature range for crayfish is generally 20℃ to 32℃, when they are most active and eat the most. At the same time, the water depth they adapt to is between 30 cm and 1.5 meters. Such a water depth is conducive to the growth of aquatic plants and the growth and reproduction of crayfish. When breeding crayfish, the aquatic plant coverage rate in the pond needs to reach more than 60%. At the same time, different types of aquatic plants are also needed to provide the habitat and food needed by crayfish, and it can also help improve water quality and increase the dissolved oxygen content in the water.

[0003] Application No. CN112931359A proposes an underwater feed feeding device, including a net cage, a buoyancy box, a receiving tray and a feeding mechanism, wherein the buoyancy box is arranged in the net cage and floats on the water surface, the receiving tray is arranged below the buoyancy box and sinks in the water body, the receiving tray is connected to the buoyancy box, the feeding mechanism is arranged on the net cage, the feeding mechanism is connected to the buoyancy box through a conveying pipeline, the feeding mechanism is used to convey feed to the buoyancy box, and the buoyancy box is used to put feed underwater;

[0004] In the prior art, feed for crayfish farming is thrown on the water surface, and the water depth that crayfish adapt to is between 30cm and 1.5m. Some feed will float on the water surface and be easily preyed upon by birds on the water surface. When the temperature is too high or too low, crayfish will not surface to find food, resulting in low feed utilization rate. In the above patent, feed is directly fed underwater. When crayfish are farmed, the coverage rate of aquatic plants in the pond is at least 60%. During the moving feeding process of the equipment, the receiving tray and its pull rope will be entangled by the aquatic plants, thereby destroying the growth environment of the crayfish. At the same time, the entangled aquatic plants will shrink back with the pull rope when the pull rope shrinks, which can easily cause damage to the equipment and reduce its service life.

[0019] Compared with the prior art, the present invention provides a feeding device for seedling cultivation and a feeding method for crayfish farming, which have the following beneficial effects:

[0020] 1. By installing the feeding unit on both sides of the floating plate, the feed in the storage silo enters the inner ring plate through the connecting pipe, and then the feed is driven by the rotating transmission shaft and the inner ring plate to rotate together. At this time, the feed will slide into the spreading pipe along the inclined surface of the material dividing partition, and when the spreading pipe rotates out of the limit cover, the feed will be scattered into the air along the inner wall of the spreading pipe, thereby throwing the feed on the water surface for feeding, and the rotation speed of the transmission shaft is adjustable, and then the rotation speed of the transmission shaft can be adjusted according to the weather and water temperature during feeding, thereby controlling the centrifugal force of the feed entering between the inner ring plate and the outer ring plate when following the rotation of the transmission shaft, changing the force of the feed thrown from the feed pipe to the water surface, and then changing the size of the feed throwing range, which is convenient for the staff to change the feed throwing range at any time according to the weather and water temperature, increasing the comfort of the staff and the practicality of the equipment.

[0021] 2. By creating a height difference between the connecting pipe and the feed pipe, the feed inside the feed unit can automatically flow into the feed pipe under the action of gravity. When the transmission shaft drives the inner ring plate, the dividing baffle plate and the outer ring plate to rotate, the card plate will remain stationary, so that the feed scattered at the outlet of the feed pipe is evenly distributed in the area separated by the dividing baffle plate between the inner ring plate and the outer ring plate, so that the amount of feed thrown on the water surface each time is the same and uniform, preventing too much feed from being thrown in a certain place, which will prevent the crayfish from being able to feed completely and cause damage to the water quality.

[0022] 3. By installing multiple groups of feeding units, and the internal structures of the multiple groups of feeding units are the same, the range intervals for scattering feeds by the multiple groups of feeding units are set similarly, so that the scattering range is preferably downward. At this time, the double-axis motor drives the transmission shaft to rotate through the fixed connecting plate, the reducer, and the linkage on the other side, and then the transmission shaft makes the feed entering the feeding unit along the feeding pipe generate centrifugal force, so that the feed is scattered along the outlet of the feeding unit and the opening range of the limit cover, so that the feed is directly fed underwater, thereby reducing the impact of external factors on the feed throwing process, thereby improving the utilization rate of the feed and preventing excessive feed residues from polluting the water quality.

DETAILED DESCRIPTION

[0032] 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.

[0033] Example 1, reference Figure 1 - Figure 8 , which is the first embodiment of the present invention, provides a feeding device for seedling cultivation, including a power unit 1, a feeding unit 3 and a feeding unit 6, wherein the feeding unit 3 is arranged above the power unit 1, and a group of feeding units 6 are arranged at both ends of the power unit 1; the power unit 1 includes a floating plate 11, and a fan wheel 12 is arranged on the outer side of the floating plate 11; the feeding unit 3 includes a storage silo 31 capable of simultaneously loading floating feed and sinking feed, and a connecting pipe 33 is arranged at the bottom of the storage silo 31;

[0034] The unloading unit 6 includes a throwing assembly 4 and a limiting assembly 5. The throwing assembly 4 includes a transmission shaft 41 and a plurality of material distribution chambers evenly distributed on the outside of the transmission shaft 41. A material spreading pipe 45 is arranged on the outside of each material distribution chamber. The limiting assembly 5 includes two positioning plates 51 rotatably sleeved on the transmission shaft 41. One side of one of the positioning plates 51 is provided with a feeding pipe 55 connected to the connecting pipe 33, so that the floating feed and the sinking feed in the storage bin 31 can enter the two groups of unloading units 6 respectively.

[0035] By driving the transmission shaft 41 to rotate at a constant speed, the feed can be evenly introduced into several distribution chambers. The feed in the distribution chamber is scattered from the spreading tube 45 under the action of centrifugation. The floating feed floats on the water surface after being scattered, and the sinking feed sinks into the water after being scattered, so that crayfish located at different heights in the water can forage separately; the outer side of the positioning plate 51 is rotatably connected with a limiting cover 53 covering the outer side of the spreading tube 45. When the limiting cover 53 is rotated at different angles, the exposed spreading tube 45 faces different directions, so that the feed scattered by the throwing component 4 falls into the water in different directions.

[0036] Furthermore, the outer side of the transmission shaft 41 is fixedly connected with an inner ring plate 42, the outer side of the inner ring plate 42 is equidistantly fixedly connected with a material dividing baffle 43, the outer side of the material dividing baffle 43 is fixedly connected with an outer ring plate 44, and a material dividing cavity is formed between the inner ring plate 42, the outer ring plate 44 and two adjacent material dividing baffles 43, and the outer surface of the outer ring plate 44 is evenly and fixedly connected with a plurality of material spreading pipes 45, and the material spreading pipes 45 correspond one-to-one to the material dividing cavity.

[0037] When in use, the staff adds the pre-mixed feed into the feed unit 3, and then the feed enters the feed pipe 55 through the connecting pipe 33. The feed in the feed pipe 55 passes through the positioning plate 51 along the feed pipe 55 and enters the distribution cavity composed of the inner ring plate 42, the distribution baffle plate 43, and the outer ring plate 44. When the transmission shaft 41 rotates, the inner ring plate 42 and the distribution baffle plate 43, the outer ring plate 44, and the spreading pipe 45 connected thereto will be driven to rotate together, and there is a high gap between the outlet of the feed pipe 55 and the connecting pipe 33. The difference in degree makes the feed scattered at the outlet of the feed pipe 55 uniform, and the transmission shaft 41 drives the inner ring plate 42 to rotate at a uniform speed, so that the feed scattered at the feed pipe 55 is evenly distributed in a plurality of distribution chambers, and then the feed is driven by the rotating transmission shaft 41 and the inner ring plate 42 to rotate together, and at this time, the feed will slide into the spreading pipe 45 along the inclined surface of the distribution partition 43, and when the spreading pipe 45 rotates out of the limit cover 53, the feed will be scattered into the air along the inner wall of the spreading pipe 45, so that the feed is thrown into the water to feed the crayfish;

[0038] The rotation speed of the transmission shaft 41 and the position of the limit cover 53 can be adjusted according to the actual feeding needs; according to the weather and water temperature during feeding, for example, when the temperature is between 20°C and 32°C, the crayfish are most active, have the largest food intake, and have the widest foraging range, and can forage both underwater and above water. At this time, feed can be fed to the above-water and underwater at the same time, so that each accounts for 50%. When the temperature is too high or too low, the crayfish will be at the bottom of the water to maintain its body temperature. At this time, the feed needs to be fed underwater to facilitate the crayfish to forage and grow, and then the rotation of the transmission shaft 41 is adjusted. The speed is controlled, thereby controlling the centrifugal force of the feed entering between the inner ring plate 42 and the outer ring plate 44 when following the rotation of the transmission shaft 41, changing the force of the feed thrown from the feed pipe 55 to the water surface, and then changing the size of the feed throwing range, which is convenient for the staff to change the feed throwing range according to the weather and water temperature at any time, increasing the comfort of the staff and the practicality of the equipment. It is particularly noted that the connecting pipe 33 and the feed pipe 55 are preferably metal pipes, so that the positioning plate 51 can be supported and fixed, so that the outer ring plate 44 can rotate stably;

[0039] Floating feeds tend to float on the water surface, while sinking feeds tend to sink to the bottom of the water. Under different temperatures, the foraging areas of crayfish are different. Sinking feeds are directly submerged in water, which is convenient for crayfish near the bottom of the water to forage, reducing the sinking time of sinking feeds in the water, thereby increasing the foraging time of crayfish. Floating feeds float on the water surface, which is convenient for crayfish near the water surface to forage. At this time, crayfish are foraging on the water surface, which is convenient for staff to directly observe the foraging situation of crayfish, and adjust the feed ratio at any time according to their foraging situation, further improving the utilization rate of feed; by allowing crayfish in different water layers to eat feed, the utilization rate of feed is increased, while preventing feed from polluting water quality;

[0040] By setting a rotatable limit cover 53, the exposed spreading tube 45 faces different directions when the limit cover 53 rotates around the positioning plate 51 at different angles, so that the feed can be scattered upward or downward, and then the scattered feed falls into the water in different directions, thereby improving the spreading efficiency. In particular, it is affected by external factors such as wind force, scattering force, equipment scattering outlet size, etc. At the same time, when approaching the edge of the breeding pond, scattering upwards will directly scatter the feed. At this time, scattering the feed directly downward is the preferred option, thereby reducing the impact of external factors on feed scattering and making the feed scatter evenly.

[0041] Furthermore, a fixed connecting plate 23 is fixedly installed on the top of the floating plate 11, and a mounting seat 14 is fixedly installed in the middle of one side of the fixed connecting plate 23. A dual-axis motor 15 is provided inside the mounting seat 14. Reducers 16 are provided on both sides of the fixed connecting plate 23, and a linkage 17 is provided at one end of the reducer 16. The linkage 17 cooperates with the transmission shaft 41 to enable the dual-axis motor 15 to drive the transmission shaft 41 to rotate.

[0042] The power at the output end of the dual-axis motor 15 is transmitted to the reducer 16, and then the reducer 16 reduces the speed of the dual-axis motor 15, and the coupling 17 changes its transmission direction and drives the transmission shaft 41 to start rotating, wherein the coupling 17 can adopt any structure in the prior art that can link the reducer 16 with the transmission shaft 41, preferably the right-angle steering gear in Chinese patent CN212105533U.

[0043] Furthermore, a rotating groove 46 is provided on the inner side of the outer ring plate 44, and a clamping plate 52 corresponding to the rotating groove 46 is provided on the outer side of the positioning plate 51, and the clamping plate 52 is rotatably connected to the rotating groove 46. The two positioning plates 51 are respectively fixedly connected to the floating plate 11 through brackets (not shown in the figure), so that when the transmission shaft 41 drives the inner ring plate 42, the dividing baffle 43, and the outer ring plate 44 to rotate, the clamping plate 52 will remain stationary, so that the feed scattered from the outlet of the feed pipe 55 is evenly distributed in the dividing cavity separated by the dividing baffle 43 between the inner ring plate 42 and the outer ring plate 44, so that the amount of feed thrown on the water surface each time is the same and uniform.

[0044] Furthermore, a clamping positioning structure is provided between the positioning plate 51 and the limiting cover 53 , and a circular groove 54 is provided on the outer side of the limiting cover 53 .

[0045] The clamping and positioning structure includes a clamping block, a clamping slot, a screw hole and a screw (not shown in the figure). The outer arc surface of the positioning plate 51 is evenly provided with clamping blocks, and the inner arc surface of the limiting cover 53 is evenly provided with clamping slots. The clamping blocks and the clamping slots are convenient for disassembly and assembly. There is an overlapping area on the surface of the positioning plate 51 and the limiting cover 53, and screw holes are provided at the overlapping areas. When the limiting cover 53 is rotated until the screw hole on its surface corresponds to one of the screw holes on the surface of the positioning plate 51, the two screw holes are tightened and fixed by screws, so that the limiting cover 53 can be fixed on the positioning plate 51 at a certain angle; the clamping and positioning structure can also adopt other structures in the prior art that can make the limiting cover 53 rotate around the positioning plate 51 at a certain angle and remain fixed;

[0046] The limiting cover 53 is movably connected to the outer side of the clamping plate 52, so as to adjust the range of the feed scattering tube 45 inside the limiting cover 53 to scatter the feed outward, so that the feed inside the scattering tube 45 can be accurately thrown onto the water surface, and at the same time, part of the feed that is not thrown out will rub and collide with the inner wall of the limiting cover 53, so that the feed will be formed into small particles or powder, and then when the scattering tube 45 rotates in the limiting cover 53, the scattering tube 45 will squeeze the small particles or powder of feed and discharge it to the water surface along the circular groove 54, so as to prevent the crushed feed from accumulating in the limiting cover 53.

[0047] Furthermore, the storage silo 31 is rotatably equipped with a transmission shaft 32, and a stirring column 35 is provided on the outside of the transmission shaft 32. A vertical plate 34 located on the outside of the transmission shaft 32 is fixedly installed inside the storage silo 31. A connecting rod 36 is movably provided on the top of the storage silo 31, and top covers 37 are provided at both ends of the connecting rod 36. A handle 38 is provided on the top of the connecting rod 36. The stirring column 35 is driven to rotate by the transmission shaft 32, thereby preventing the feed inside the storage silo 31 from accumulating at the bottom of the inner wall of the storage silo 31 when the feeding is almost finished, and unable to fall into the connecting pipe 33. At the same time, the vertical plate 34 divides the storage silo 31 into two parts, so that floating feed and sinking feed are loaded respectively, so that the throwing assembly 4 and the unloading unit 6 are fed respectively through the connecting pipe 33 at the bottom of the storage silo 31, so that the staff can separately allocate the feed at the two places inside the storage silo 31 according to the spreading method, thereby improving the utilization rate of the feed.

[0048] Furthermore, there are at least two groups of stirring columns 35, and the lowest stirring column 35 is flush with the bottom of the inner wall of the storage silo 31, wherein each group of stirring columns 35 has two stirring columns 35 and are respectively located on both sides of the vertical plate 34, and the bottom of the transmission shaft 32 extends to the outside of the storage silo 31 and is fixedly connected to the output shaft of the servo motor outside the storage silo 31, and the two groups of stirring columns 35 are driven by the servo motor to rotate in the storage silo 31, and the rotation range is preferably 120°. Starting from the time when the stirring column 35 and the vertical plate 34 are perpendicular to each other, the stirring column 35 first rotates 60° clockwise and then rotates 120° counterclockwise, so that the two groups of stirring columns 35 rotate back and forth inside the storage silo 31, thereby preventing the feed inside the storage silo 31 from solidifying together and unable to fall out, thereby improving the utilization rate of the feed.

[0049] Furthermore, a protective cover 13 located on one side of the floating plate 11 is provided on the outer side of the impeller 12. The protective cover 13 is fixedly connected to the floating plate 11. The protective cover 13 protects the impeller 12 during movement to prevent the river bank from damaging the impeller 12 and to prevent mud or aquatic plants from entering the transmission bearing of the impeller 12 and causing blockage therein.

[0050] Furthermore, a control unit 2 is provided on the float 11, and the control unit 2 includes an information processor 21 arranged on the outside of the storage silo 31. A signal transceiver 22 is provided on one side of the information processor 21, and the remote control signal of the staff is received through the signal transceiver 22. At this time, the information processor 21 controls the dual-axis motor 15, the servo motor and the impeller 12 to work according to the information, so that the equipment can move and spread materials, thereby reducing the labor intensity of the staff and increasing the comfort of the staff.

[0051] Working principle: During use, the staff first mixes the feed according to the type of crayfish and its biological habits, and according to the season, temperature and weather at that time, so that the floating feed and the sinking feed are located on both sides of the storage silo 31 respectively. The staff holds the remote control and remotely controls the entire device through the information processor 21 and the signal transceiver 22. First, the fan wheel 12 is controlled to work, so that the floating plate 11 and the equipment above it move in the pond to spread the feed. At this time, the protective cover 13 on the outside of the fan wheel 12 protects it to prevent the fan wheel 12 from being damaged when the equipment is at the edge of the pond, thereby increasing the safety and service life of the fan wheel 12.

[0052] When the floating plate 11 moves in the pond to spread the feed, the feed in the storage silo 31 will enter the feed pipe 55 through the connecting pipe 33 at the bottom thereof, and the feed entering the feed pipe 55 will pass through the positioning plate 51 along the feed pipe 55 and enter the distribution cavity composed of the inner ring plate 42, the distribution baffle 43, and the outer ring plate 44. The dual-axis motor 15 is controlled to work, so that the dual-axis motor 15 drives the transmission shaft 41 to rotate through the reducer 16 and the coupling 17. When the transmission shaft 41 rotates, the inner ring plate 42 and the distribution baffle 43, the outer ring plate 44, and the spreading pipe 45 connected thereto will be driven to rotate together, and there is a height difference between the outlet of the feed pipe 55 and the connecting pipe 33, so that the feed is spread out at a uniform speed at the outlet of the feed pipe 55, and the transmission shaft 41 drives the inner ring plate 42 to rotate at a uniform speed, so that the feed spread out from the feed pipe 55 is evenly distributed on the inner ring plate 42, the outer ring plate 43 and the distribution baffle 43. The feed is then driven by the rotating transmission shaft 41 and the inner ring plate 42 to rotate together. At this time, the feed will slide into the feeding tube 45 along the inclined surface of the material dividing partition plate 43. When the feeding tube 45 rotates out of the limiting cover 53, the feed will be scattered into the air along the inner wall of the feeding tube 45, so that the feed is thrown on the water surface for feeding. The limiting cover 53 limits the throwing range of the feeding tube 45. The rotation speed of the transmission shaft 41 can be adjusted according to the weather and water temperature during feeding, thereby controlling the centrifugal force of the feed entering between the inner ring plate 42 and the outer ring plate 44 when following the rotation of the transmission shaft 41, changing the force of the feed thrown from the feeding tube 55 to the water surface, and then changing the throwing range of the feed, which is convenient for the staff to change the throwing range of the feed according to the weather and water temperature at any time, thereby increasing the comfort of the staff and the practicality of the equipment;

[0053] At the same time, the servo motor is controlled to drive the transmission shaft 32 to rotate, and then the transmission shaft 32 drives the stirring column 35 on its outer side to rotate, so that the stirring column 35 at the lowest point rotates back and forth at the bottom of the storage silo 31, and the feed remaining at the bottom of the inner wall of the storage silo 31 is swept into the connecting pipe 33, and at the same time, the feed in the storage silo 31 is prevented from solidifying together and unable to fall down, thereby reducing the waste of feed and improving the utilization rate of feed.
