Description

Technical Field

[0001] The invention relates to the technical field of crustacean aquaculture, in particular to a breeding device and a breeding method for Procambarus clarkii. Background Art

[0002] Procambarus clarkii, also known as crayfish, is a rapidly developing industry in aquaculture in recent years. Procambarus clarkii is very prone to fighting over food during feeding. Crayfish are typical territorial animals and will actively attack fellow crayfish that enter their territory. This is one of the key issues that need to be addressed in artificial breeding.

[0003] Because food appears in a concentrated area during feeding, it will attract a large number of lobsters to gather, greatly increasing the chances of contact and conflict between individuals. In addition, artificial breeding usually has a high density, which will further intensify competition. It is easy for the claws, legs, tentacles and other parts of the crayfish to be easily pinched or torn. Severe fighting may cause vulnerable individuals (such as soft-shelled shrimp that have just shed their shells) to be killed or even eaten by their own kind. Continuous fighting causes high tension in the group, and fighting consumes a lot of energy that should be used for growth, resulting in reduced feeding efficiency and slower growth rate. The existing feed feeders on the market are difficult to solve this type of core pain point in breeding, resulting in increased breeding losses and reduced breeding efficiency.

[0028] In actual application of this embodiment, when the device is used to raise crayfish, the main frame 101 in the device is floated on the water surface through a plurality of floats 104, and the lifting frame 102 is connected to a plurality of telescopic motors so that the lifting frame 102 has a lifting function in the third direction z. Since a plurality of traction rods 105 are fixedly connected to the lifting frame 102, and the traction rods 105 are fixedly connected to the outer separation cylinder 202, the lifting frame 102 can pull the feeding plate 201 synchronously in the lifting process. The feeding tray 201 is lifted and lowered in the third direction z. The feeding tray 201 has a relative lifting state and sinking state in the third direction z. When the feeding tray 201 is in the sinking state, the partition column 206 at the bottom of the feeding tray 201 contacts the bottom of the breeding pond. At this time, after the feeding tray 301 sinks following the feeding tray 201, the top surface of the feeding tray 301 and the top surface of the feeding tray 201 are aligned in the third direction z. The first feeding cavity a1 is set between the partition holes 203 at the outer diameter end of the outer partition cylinder 202. The interior of 202 is set as the second feeding chamber a2, and the third feeding chamber a3 is set between the bottom surface of the feeding plate 201 and the bottom of the pool. The feed released into the outer separation cylinder 202 by the distributor mechanism 4 and the press mechanism 5 is distributed in the first feeding chamber a1 and the second feeding chamber a2. The separation hole 203 is used to prevent large-sized crayfish from entering the second feeding chamber a2, while medium-sized crayfish can pass through the separation hole 203 to enter the second feeding chamber a2 to feed. The partition plate 204 can separate the large-sized crayfish into the second feeding chamber a1 and the medium-sized crayfish. The feed residues of the medium-sized crayfish can fall into the third feeding chamber a3 through the seepage holes 302, and some small-sized crayfish with weaker constitutions can enter the third feeding chamber a3 through the gaps between the plurality of partition columns 206 to feed. In this way, the device can effectively separate the large, medium and small-sized crayfish when supplying feed, thereby reducing the risk of broken limbs of large-sized crayfish due to fighting during feeding, and reducing the possibility of chase and fighting between crayfish of different sizes during the process of competing for food.

[0029] Furthermore, the aperture of the feed infiltration hole 302 is smaller than that of the partition hole 203, allowing residual feed to fall into the third feeding cavity a3 for small-sized shrimp to eat.

[0030] See also Figure 4 and Figure 7 In a preferred embodiment of the present invention, the feed tray assembly 3 further includes a limiting groove 304, a bottom notch 305 and a layer plate 306. The limiting groove 304 is arranged at the outer diameter end of the cavity tube 303, and the slot member 205 is slidingly assembled in the limiting groove 304. The bottom notch 305 is circumferentially arranged on the cylinder body of the cavity tube 303 and is arranged close to one side of the feeding tray 201. The layer plate 306 is fixedly arranged in the inner cavity of the cavity tube 303.

[0031] In actual application of this embodiment, the limiting groove 304 is set at the outer diameter end of the cavity cylinder 303, and the slot member 205 is limited and slidably assembled in the limiting groove 304, so that when the outer separation cylinder 202 is pulled and lifted along the positive direction of the third direction z by the traction rod 105, the slot member 205 slides along the limiting groove 304, and the feeding tray 301 remains stationary in the third direction z, so that a gap is formed between the outer separation cylinder 202 and the feeding tray 301, and the material is drilled in. The medium-sized crayfish in the second feeding chamber a2 can leave the second feeding chamber a2 through the gap, while the large-sized crayfish gathered in the first feeding chamber a1 can freely leave the first feeding chamber a1. When the slot member 205 slides up and abuts the upper end of the limiting groove 304, the cavity tube 303 moves along the positive direction of the third direction z with the feeding plate 201, so that when the dividing column 206 is detached from one side of the pool bottom, the small-sized crayfish located in the third feeding chamber a3 can freely leave.

[0032] See also Figure 7 In a preferred embodiment of the present invention, the distributor mechanism 4 includes a swirling bucket 401, a release tube 402, a hole mold 403, and a driven bevel gear 408. The swirling bucket 401 is rotatably mounted on the layer plate 306. The release tube 402 is fixedly installed at the bottom of the swirling bucket 401. The hole mold 403 is installed in the release tube 402. The driven bevel gear 408 is fixedly arranged at the outer diameter end of the swirling bucket 401.

[0033] In actual use of this embodiment, the swirling bucket 401 is rotatably mounted on the layer plate 306. When the feed filled in the swirling bucket 401 passes through the hole die 403 on one side of the discharge tube 402, the hole die 403 can squeeze the feed into a strip shape for delivery. The driven bevel gear 408 on the outer wall of the swirling bucket 401 drives the swirling bucket 401 to rotate around a fixed axis when in a driven state.

[0034] Furthermore, the hole mold 403 adopts a detachable structure, which can extrude feeds of different particle sizes according to different shrimp species.

[0035] Furthermore, the feed used in the equipment is wet feed, such as earthworms, snails, clams, livestock and poultry waste, fish intestines and other crushed and mixed feed.

[0036] See also Figure 7In a preferred embodiment of the present embodiment, the distributor mechanism 4 further includes a fixed sliding sealing ring 404, a dynamic sliding sealing ring 405, a drainage pipe 406 and a discharge pipe 407, the fixed sliding sealing ring 404 is fixedly arranged in the cavity tube 303, and the fixed sliding sealing ring 404 is connected to the drainage pipe 406, one end of the dynamic sliding sealing ring 405 is fixedly connected to the swirling bucket 401, and the other end of the dynamic sliding sealing ring 405 is slidingly and sealingly connected to the fixed sliding sealing ring 404, and the other end of the dynamic sliding sealing ring 405 is also connected to the discharge pipe 407.

[0037] In actual application of this embodiment, the fixed sliding sealing ring 404 is fixedly arranged in the cavity tube 303, and one end of the dynamic sliding sealing ring 405 is fixedly connected to the swirling bucket 401, and the other end of the dynamic sliding sealing ring 405 is slidingly and sealingly connected to the fixed sliding sealing ring 404. The drainage pipe 406 connected to one side of the fixed sliding sealing ring 404 is used to introduce water flow, so that the water flow passes through the fixed sliding sealing ring 404 and the dynamic sliding sealing ring 405 pump to the discharge pipe 407. The discharge pipe 407 is arranged at the feed extrusion end, and the feed is pushed to various positions on the bottom of the pool by the water flow.

[0038] See also Figure 7 In a preferred embodiment of the present invention, the distributor mechanism 4 further includes a feed release bin 409, a rotary cover 410, an impeller 411, and an L-shaped feed pipe 412. The feed release bin 409 is fixedly mounted on the bottom of the swirling bucket 401, and the release pipe 402 and the discharge pipe 407 are both connected to the inner cavity of the feed release bin 409. The rotary cover 410 is rotatably mounted on one side of the feed release bin 409. The impeller 411 is provided at one end of the rotary cover 410, and the L-shaped feed pipe 412 is fixedly connected to the other end of the rotary cover 410.

[0039] In actual use of this embodiment, the feed release bin 409 is fixedly mounted at the bottom of the swirling bucket 401, and the release pipe 402 and the drainage pipe 407 are both connected to the inner cavity of the feed release bin 409. Strips of feed are passed through the release pipe 402 and transported into the inner cavity of the feed release bin 409. The drainage pipe 407, located on one side of the inner cavity of the feed release bin 409, continuously pumps water to discharge the feed toward the side of the rotary cover 410. Because an impeller 411 is fixedly mounted on one side of the rotary cover 410 and rotatably mounted on the feed release bin 409, the water flow drives the impeller 411 to rotate during operation, thereby driving the rotary cover 410 to rotate. This causes the water containing the feed to pass through the central through-hole of the rotary cover 410 and be discharged along the L-shaped feed pipe 412 to the bottom of the aquaculture pond.

[0040] Further, the spray port of the L-shaped material pipe 412 and the rotating shaft of the rotary cover 410 are arranged eccentrically, so that the height of the spray port of the L-shaped material pipe 412 is constantly changed in the third direction z. When the L-shaped material pipe 412 is in the high spray position, the feed can fall through the partition hole 203 into the first feeding cavity a1. When the L-shaped material pipe 412 is in the low spray position, the feed can fall into the second feeding cavity a2. Since the feed release bin 409 rotates with the rotary bucket 401, the feed output through the L-shaped material pipe 412 can uniformly cover the first feeding cavity a1 and the second feeding cavity a2, reducing the probability of fighting among the same body type of kempfi crawfish.

[0041] Please refer to Figure 5 and Figure 6 In a preferred embodiment of the present application, the material pressing mechanism 5 comprises a material pressing pipe 501, a material pressing piston 502, a material discharging pipe 503, and a material containing bucket 504. The material pressing pipe 501 is fixedly arranged in the inner cavity of the cavity cylinder 303 and communicates with the rotary bucket 401. The material pressing piston 502 is slidably arranged in the material pressing pipe 501. The material discharging pipe 503 is arranged in the inner cavity of the cavity cylinder 303, and the bottom of the material discharging pipe 503 communicates with the material pressing pipe 501. The material containing bucket 504 is arranged at the top of the cavity cylinder 303 and communicates with the material discharging pipe 503.

[0042] In actual application, the material pressing pipe 501 and the material discharging pipe 503 are fixedly arranged in the inner cavity of the cavity cylinder 303, and the bottom of the material discharging pipe 503 communicates with the material pressing pipe 501. The material containing bucket 504 communicates with the material feeding bucket 103 and is used to contain the feed to be output. The material pressing piston 502 reciprocates along the third direction z in the driving state. When the material pressing piston 502 moves to the negative direction of the third direction z, the feed in the inner cavity of the material pressing pipe 501 can be extruded into the rotary bucket 401, because the bottom of the material pressing pipe 501 communicates with the inner cavity of the rotary bucket 401 and is rotatably arranged on the rotary bucket 401. When the material pressing piston 502 moves along the positive direction of the third direction z, the material pressing piston 502 slides away from the slot at one side of the material discharging pipe 503, so that the feed in the material discharging pipe 503 can fall into the inner cavity of the material pressing pipe 501 through the slot, and then the feed is continuously extruded into the rotary bucket 401 for pumping through the reciprocating movement of the material pressing piston 502.

[0043] Please refer to Figure 6In a preferred embodiment of the present invention, the press mechanism 5 further includes a driver 505, a main driving rod 506, a stirring driving rod 507, a stirring driven rod 508, a stirring tooth 509, a driven wheel 510, a secondary driving rod 511, a press driving rod 512, a press driven rod 513 and a driving bevel gear 514.

[0044] In actual application of this embodiment, the driver 505 is fixedly arranged on one side of the cavity cylinder 303, and the movable shaft of the driver 505 and the main driving rod 506 are coaxially fixedly connected, so that when the main driving rod 506 rotates, the stirring driving rod 507 on the end side drives the stirring driven rod 508 to continuously rise and fall during the fixed axis rotation, so that the stirring teeth 509 on one side of the stirring driven rod 508 continuously stir the feed in the inner cavity of the discharge tube 503, so that the feed quickly falls to the connection between the discharge tube 503 and the pressing tube 501 under the action of gravity. The slot on the through side prevents the feed from being blocked inside the discharge pipe 503. The driven wheel 510 synchronously drives the auxiliary driving rod 511 to rotate during the rotation process, and then drives the pressing driving rod 512 to rotate through the auxiliary driving rod 511, so that the pressing driven rod 513 connected to the end side of the pressing driving rod 512 drives the pressing piston 502 to reciprocate in the third direction z during the rotation process. The driving bevel gear 514 engages and drives the driven bevel gear 408 to rotate in the driving state, so that the swivel bucket 401 rotates on a fixed axis on the layer plate 306.
