Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture, and particularly relates to a seedling-raising device for aquaculture. Background Art

[0002] Seedling-raising for aquaculture refers to the process of using specific equipment and facilities during aquaculture to simulate or create suitable ecological environmental conditions to promote the reproduction and early development of aquatic organisms (such as fish, shrimps, crabs, shellfish, etc.), so as to cultivate healthy and vigorous seedlings, providing high-quality seedling resources for subsequent aquaculture production. This process is crucial for improving the yield and quality of aquaculture;

[0003] However, most of the current seedling-raising equipment for aquaculture is carried out in seedling-raising ponds. In order to carry out a large amount of aquaculture seedling-raising work at one time, the water ponds are designed to have a large area and a relatively deep bottom. Therefore, after the seedling-raising is completed, it is difficult for the staff to salvage the aquatic seedlings from the breeding ponds. Summary of the Invention

[0004] The purpose of the present invention is to provide a seedling-raising device for aquaculture, which is used to solve the problems existing in the background art.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0006] A seedling-raising device for aquaculture, including a breeding frame, characterized in that: a high platform is provided at the bottom of one side of the breeding frame, an inclined plane is provided between the high platform and the bottom of the breeding frame, a first filter plate is slidably assembled left and right in the breeding frame, the breeding frame is provided with a driving mechanism matching the first filter plate, a receiving groove with an opening downward is provided inside the first filter plate, a second filter plate is slidably assembled up and down in the receiving groove, an installation groove is provided at the bottom of the second filter plate, rollers are assembled in the installation groove, two sleeves are symmetrically provided on the upper side of the first filter plate, sliders are slidably assembled in the two sleeves, connecting rods extending into the installation groove and connecting with the second filter plate are provided on the lower sides of the two sliders, and springs are provided on the upper sides of the two sliders.

[0007] The two sliders are both slidably and hermetically assembled in the sleeves, a water spraying pipe is provided on the side of the second filter plate facing the high platform, a number of spray nozzles are assembled on the water spraying pipe, water outlet hoses are provided between the water spraying pipe and the upper ends of the two sleeves, water outlet check valves are assembled on the two water outlet hoses, and a water replenishing mechanism connecting with the upper sides of the two sleeves is provided on the side of the second filter plate away from the high platform.

[0008] The water replenishing mechanism includes a water suction pipe connected to the lower side of the second filter plate, a number of water suction heads are assembled on the water suction pipe, a water inlet hose connecting with the upper ends of the two sleeves is provided on the water suction pipe, and water inlet check valves are assembled on the two water inlet hoses.

[0009] The driving mechanism includes two support blocks which are respectively arranged on the left and right sides of the breeding frame. A screw rod is rotatably assembled between the two support blocks. The screw rod is threadedly connected with a driving block connected to the upper side of the first filter plate. One of the support blocks is equipped with a motor that is drivingly connected to the screw rod.

[0010] Through grooves are provided on both the front and rear sides of the storage groove, and sliding strips matching the through grooves are provided on both the front and rear sides of the first filter plate.

[0011] A drain pipe is provided on one side of the breeding frame, and the drain pipe is equipped with a control valve.

[0012] A transparent observation window is provided on the outer surface of the breeding frame.

[0013] The present invention has the following technical advantages compared with the prior art:

[0014] 1. By driving the first filter plate and the second filter plate to move through the driving mechanism, the aquatic fry can be effectively driven to the high platform. Since the area of the high platform is small and the height is appropriate, it enables the staff to grab the fry more conveniently and improves the work efficiency.

[0015] 2. The rollers on the second filter plate can drive the fry during the movement. When the rollers move to the inclined surface, guided by the inclined surface, the second filter plate will rise and be received into the first filter plate, and at the same time, further drive the fry to the high platform. This design is both ingenious and practical.

[0016] 3. When the slider moves in the sleeve, negative pressure will be formed and clear water will be automatically sucked in through the water replenishing mechanism. When the second filter plate moves to the inclined surface, the clear water in the sleeve will be sprayed into the spray pipe through the water outlet hose and sprayed out from the nozzle to drive the fry facing the high platform of the rollers, preventing the fry from being crushed.

[0017] 4. By driving the screw rod to rotate through the motor, and then driving the driving block and the first filter plate and the second filter plate to move left and right, this design makes the movement and driving process of the whole device more flexible and controllable.

[0018] 5. When the second filter plate slides up and down in the storage groove, the sliding strips slide in the through grooves, reducing the gap between the side surface of the second filter plate and the inner wall of the breeding frame, improving the driving effect on the aquatic fry. At the same time, the transparent observation window on the breeding frame is convenient for the staff to observe the cultivation situation of the fry. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] As Figures 1-3 shown, a seedling raising device for aquaculture of the present invention includes a breeding frame 1, and is characterized in that: a high platform 11 is provided at the bottom of one side of the breeding frame 1, an inclined plane 12 is provided between the high platform 11 and the bottom of the breeding frame 1, a first filter plate 13 is slidably assembled left and right in the breeding frame 1, a driving mechanism matching the first filter plate 13 is provided on the breeding frame 1, a storage groove 14 with an opening downward is provided inside the first filter plate 13, a second filter plate 15 is slidably assembled up and down in the storage groove 14, an installation groove 16 is provided at the bottom of the second filter plate 15, a roller 17 is assembled in the installation groove 16, two sleeves 2 are symmetrically provided on the upper side of the first filter plate 13, a slider 21 is slidably assembled in the two sleeves 2, a connecting rod 22 extending into the installation groove 16 and connected to the second filter plate 15 is provided on the lower side of the two sliders 2, and a spring 23 is provided on the upper side of the two sliders 2.

[0027] When carrying out aquaculture seedling raising, the driving mechanism drives the first filter plate 13 to move. Since the second filter plate 15 is installed on the lower side of the first filter plate 13, the second filter plate 15 follows the first filter plate 13 to move until the first filter plate 13 and the second filter plate 15 move to the inner wall of the side far from the high platform 11 in the breeding frame 1. At this time, the staff can inject clean water and aquaculture seedlings into the breeding frame 1 to carry out aquaculture seedling raising work;

[0028] After completing the aquaculture seedling rearing work, the staff can drive the first filter plate 13 and the second filter plate 15 to move towards the side close to the high platform 11 through the driving mechanism. The roller 17 will roll at the bottom of the breeding frame 1 under the movement of the second filter plate 15. When the first filter plate 13 and the second filter plate 15 move in the breeding frame 1, they will drive the aquaculture seedlings to move towards the side of the high platform 11. And when the second filter plate 15 moves to the position of the inclined surface 12, the inclined surface 12 guides upwards, and the roller 17 moves to the upper surface of the inclined surface 12. Under the guiding action of the inclined surface 12, the second filter plate 15 will move upwards in the receiving groove 14. The second filter plate 15 drives the slider 21 to move upwards in the sleeve 2 through the connecting rod 22, and drives the spring 23 to compress. Therefore, the second filter plate 15 will gradually be received into the first filter plate 13, and thus gradually drive the seedlings to the upper side of the high platform 11. When the roller 17 moves to the upper side of the high platform 11, it will drive the seedlings to the upper side of the high platform 11. With such a design, the staff can grab the seedlings on the upper side of the high platform 11. Since the area of the high platform 1 is relatively small and the height of the high platform 1 is higher than the bottom of the breeding frame 1, it is convenient for the staff to grab the aquaculture seedlings;

[0029] When it is necessary to release the aquaculture seedlings again, first move the second filter plate 13 and the first filter plate 15 away from the high platform 11 again. When the roller 17 moves past the inclined surface 12, under the action of the spring 23 stretching, it drives the slider 21 to move downwards. The slider 21 drives the connecting rod 22 to move downwards, thereby driving the second filter plate 15 to move downwards and reset.

[0030] Both sliders 21 are slidably and sealingly assembled in the sleeve 2. A water spraying pipe 24 is provided on the side of the second filter plate 15 facing the high platform 11. The water spraying pipe 24 is equipped with a number of spray heads 25. Water outlet hoses 26 are provided between the water spraying pipe 24 and the upper ends of the two sleeves 2. Both water outlet hoses 26 are equipped with water outlet one-way valves 27. A water replenishing mechanism connected to the upper sides of the two sleeves 2 is provided on the side of the second filter plate 15 away from the high platform 11.

[0031] When the slider 21 moves downwards in the sleeve 2, a negative pressure is formed on the upper side in the sleeve 2, and the clear water in the breeding frame 1 is sucked into the sleeve 2 through the water replenishing mechanism. And when the second filter plate 13 moves towards the side of the high platform 11 and the second filter plate 13 moves onto the inclined surface 12, the slider 21 will move upwards in the sleeve 2, and the clear water on the upper side in the sleeve 2 can be sprayed into the water spraying pipe 24 through the water outlet hose 26, and finally sprayed out from a number of spray heads 25. With such a design, clear water can be sprayed on the side of the roller 17 facing the high platform 11, and the seedlings on the side of the roller 17 facing the high platform 11 can be driven away. With such a design, it can prevent the angle from becoming smaller when the inclined surface 12 contacts the roller 17 and causing rolling damage to the seedlings.

[0032] The water replenishing mechanism includes a water suction pipe 3 connected to the lower side of the second filter plate 15. A number of suction heads 31 are assembled on the water suction pipe 3. The water suction pipe 3 is provided with a water inlet hose 32 connected to the upper ends of two sleeves 2. Both water inlet hoses 32 are assembled with water inlet check valves 33.

[0033] When negative pressure is formed on the upper side in the sleeve 2, clear water in the breeding frame 1 can be sucked into the upper side of the sleeve 2 through a number of suction heads 31 and the water inlet hose 23.

[0034] The driving mechanism includes two support blocks 34. The two support blocks 34 are respectively arranged on the left and right sides of the breeding frame 1. A screw rod 35 is rotatably assembled between the two support blocks 34. The screw rod 35 is threadedly connected to a driving block 36 connected to the upper side of the first filter plate 13. One of the support blocks 34 is assembled with a motor 37 in transmission connection with the screw rod 35.

[0035] Since the screw rod 35 is threadedly connected to the driving block 36, when the screw rod 35 rotates in two directions respectively, the driving block 36 can slide left and right, thereby driving the first filter plate 13 and the second filter plate 15 to move left and right.

[0036] Through grooves 4 are provided on both the front and rear sides of the storage groove 14. Slide bars 41 matching the through grooves 4 are provided on both the front and rear sides of the first filter plate 13. With such a design, when the second filter plate 15 slides up and down in the storage groove 14, the slide bars 41 slide up and down in the through grooves 4. Such a design can reduce the gap between the side surface of the second filter plate 15 and the inner wall of the breeding frame 1 and improve the driving effect on aquatic seedlings.

[0037] A drain pipe 42 is provided on one side of the breeding frame 1. The drain pipe 42 is assembled with a control valve 43. When the staff opens the control valve 43, the clear water in the breeding frame 1 is discharged out through the drain pipe 42, facilitating the replacement of clear water.

[0038] A transparent observation window is provided on the outer surface of the breeding frame 1. The design of the transparent observation window facilitates the staff to observe the seedling cultivation situation in the breeding frame 1.

[0039] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
