Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to a factory-based seedling raising pond. Background Art

[0002] In order to improve the efficiency and quality of aquaculture, fish fry are often artificially cultivated in the early stages of aquaculture. After the fry grow to a suitable stage, they are transferred to waters suitable for breeding. During the fry breeding stage, nutritious feed such as brine shrimp is added to promote the growth of the fry.

[0003] At present, conventional nursery ponds usually use manual timed and fixed-point feeding when feeding fry, but this method is time-consuming and labor-intensive and can hardly meet the needs of large-scale factory farming. Therefore, in order to facilitate the feeding of fry in the nursery pond, a separate brine shrimp incubator is usually set up in each nursery pond, and the effect of automatic feeding is achieved by setting a timer. However, this method still has the problem that the brine shrimp in the incubator is prone to die in the batch due to the fast growth cycle and needs to be replaced, which also causes cumbersome cleaning and increased breeding costs. In addition, multiple incubators are also prone to the situation that a single incubator cannot hatch due to environmental or other factors, which in turn affects the breeding of fry.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1: Figure 1-4 As shown, a factory-based nursery pool includes a nursery pool 1 and a control panel. A drainage outlet is provided at the lower side of the nursery pool 1. A cross frame 11 and a water pipe 12 are provided at the upper side of the nursery pool 1. A feeding mechanism is provided on the cross frame 11.

[0026] The feeding mechanism includes a transmission assembly, a pump suction assembly and a distributor. The transmission assembly is arranged at the upper end of the horizontal frame 11. The pump suction assembly is connected to the horizontal frame 11 through a bracket and matched with the transmission assembly in transmission connection. The distributor is arranged at the lower end of the transmission assembly.

[0027] The pump suction assembly includes an empty tube 2, a piston body 21, a connecting rod 22 and a side rod 23. The empty tube 2 is a hollow structure and is connected to the cross frame 11 through a bracket. The piston body 21 is slidingly sealed in the empty tube 2. The connecting rod 22 slidingly seals through the lower end of the empty tube 2 and is connected to the piston body 21. The side rod 23 is connected to the connecting rod 22 and is connected and matched with the transmission assembly. Compared with the upper and lower spaces of the piston body 21, the empty tube 2 is divided into two liquid chambers 24. The water pipe 12, the transmission assembly, the distributor and the two liquid chambers 24 are connected by a connecting liquid path.

[0028] When raising seedlings, a proper amount of water is injected into the seedling pond 1 and its temperature is controlled to ensure that the environment and water depth are suitable for the fry. Then, in the seedling raising stage, in order to meet the growth needs of the fry, feed needs to be put into the seedling pond 1 at regular intervals and in a fixed amount. The water pipe 12 is connected to the external water body pumping mechanism, and the water storage container connected to the external water body pumping mechanism cultivates and hatches brine shrimp. At the same time, the water pipes 12 between multiple seedling ponds 1 are interconnected to form a water circuit. When feeding, the control panel turns on the transmission component, and the transmission component is used to drive the pump suction component, wherein the side rod 23 in the pump suction component synchronizes the transmission component to move upward. The connecting rod 22 and the piston body 21 are used to pull and draw, so that negative pressure suction and pressure output are respectively generated in the two liquid chambers 24 in the empty tube 2. The water containing brine shrimp in the water pipe 12 is extracted through the connecting liquid path and sent to the distributor, so as to achieve the effect of quickly releasing the seedlings in multiple seedling ponds 1. At the same time, since the water pipe 12 connects the multiple seedling ponds 1, there is no need to set up a brine shrimp incubator separately in each seedling pond 1, and there is no need to manually release feed to the multiple seedling ponds 1, which is more suitable for the needs of factory-based seedling cultivation and reduces the consumption of manpower and material resources.

[0029] The transmission assembly includes a motor 3, a main shaft 31 and a driver. The motor 3 is fixedly arranged at the upper end of the cross frame 11. The main shaft 31 is rotatably arranged at the lower end of the cross frame 11 and is connected to the output shaft of the motor 3. An annular groove 32 is opened on the side of the main shaft 31. The driver is arranged between the main shaft 31 and the side rod 23. The annular groove 32 is continuous in the first position and has a sinusoidal structure in the plane after unfolding.

[0030] The driver includes a collar 4 and an insert 41 . The insert 41 is fixed to the inner wall of the collar 4 . The upper end of the collar 4 is connected to the side rod 23 and is slidably connected to the main shaft 31 up and down. The insert 41 is slidably engaged with the annular groove 32 .

[0031] When feeding, the motor 3 starts to drive the main shaft 31 to rotate, thereby driving the distributor to move in a circular motion in the seedling pond 1. At this time, the position of the distributor changes at any time, and the feed can be distributed to the seedling pond 1 more dispersedly and quickly, so as to achieve the effect of uniform feed delivery and promote the uniform growth progress of the fry. During the rotation of the main shaft 31, the ring 4 in the driver is slidably engaged with the annular groove 32 of the main shaft 31 through the embedded head 41, and the ring 4 is connected to the piston body 21 through the side rod 23 and the connecting rod 22. Therefore, while the piston body 21 is used to limit the ring 4, the connection between the embedded head 41 and the main shaft 31 can also achieve the effect of controlling the ring 4 to slide up and down, thereby driving the piston body 21 to move.

[0032] Example 2: Figure 2-4 As shown, in the structure of Example 1, limit rings 5 ​​are provided at intervals between the upper and lower sides of the empty tube 2 and the ends, and the connecting liquid circuit includes an inlet pipe 51, a discharge pipe and a float. The inlet pipe 51 is a three-way pipe and is respectively connected to the water pipe 12 and the two liquid chambers 24, the discharge pipe is a three-way pipe and is respectively connected to the distributor and the two liquid chambers 24, the connection points between the inlet pipe 51 and the discharge pipe and the liquid chamber 24 are all located between the corresponding side limit rings 5 ​​and the end wall of the empty tube 2, corresponding one-way valves 76 are provided between the inlet pipe 51 and the discharge pipe and the empty tube 2, and the float is connected to the inlet pipe 51 and the discharge pipe and is provided with an electrically controlled conversion valve 53.

[0033] The float includes a first hose 6 and a float plate 61 . The first hose 6 connects the float plate 61 and the electrically controlled conversion valve 53 . A liquid inlet 62 connected to the first hose 6 is opened at the lower end of the float plate 61 . An air hole 63 connected to the liquid inlet 62 is opened on the side of the float plate 61 .

[0034] A counterweight ring is also provided at the lower end of the floating plate 61, and the liquid inlet 62 and the air hole 63 of the floating plate 61 are both provided with mesh covers.

[0035] A "7"-shaped liquid groove 7 is opened in the middle of the main shaft 31. The main shaft 31 is rotated and sealed with an empty ring 71 corresponding to the liquid groove 7 and opened at the side of the main shaft 31. The empty ring 71 is connected to the lower end of the cross frame 11 through a bracket, and the empty ring 71 is connected to the drain pipe.

[0036] When extracting the liquid containing brine shrimp in the water pipe 12, the piston body 21 moves and causes the liquid chamber 24 on the corresponding side to generate negative pressure, thereby extracting the liquid in the water pipe 12 through the liquid inlet pipe 51. At this time, the liquid path connected by the electronically controlled conversion valve 53 is the liquid chamber 24, the liquid inlet pipe 51 and the water pipe 12. When the piston body 21 produces a squeezing action, the liquid in the liquid chamber 24 is input into the distributor through the liquid discharge pipe and is put into the seedling pond 1 to achieve the purpose of feeding. The one-way valve 76 provided on the liquid inlet pipe 51 and the liquid discharge pipe can ensure one-way flow of the liquid path;

[0037] Furthermore, after the feeding is completed, the control panel controls the electronically controlled conversion valve 53 to switch the liquid circuit, so that the first hose 6 of the float is connected to the liquid inlet pipe 51. At this time, the suction action of the piston body 21 will extract water and air through the liquid inlet hole 62 and the air hole 63 on the floating plate 61 connected to the first hose 6, wherein the counterweight ring is used to press down the floating plate 61, so that the air hole 63 on the side of the floating plate 61 is in a half-state in the water and the air, and the mesh cover can prevent the seedlings from being adsorbed at the opening when the water is extracted, causing blockage and the fry. Injured, and when the air is transported to the distributor through the discharge pipe and output, the air will be output from the lower side of the water body in the seedling pool 1, thereby playing the effect of supplementing oxygen to the water body, and at the same time, the cooperation of the air hole and the liquid inlet hole can make both water and air be sucked into the liquid cavity, so that the liquid cavity presents a state of both water and air. In this way, after the absorption of the brine shrimp solution is cut off, the water in the pool can be used to pump out the remaining brine shrimp in the liquid cavity, avoiding the need for frequent maintenance of the equipment after the death of these brine shrimps that cannot be discharged;

[0038] When the extracted air or water or liquid containing brine shrimp is discharged from the discharge pipe, it will be input into the empty ring 71, and the empty ring 71 is in a stationary state relative to the main shaft 31 through the connection of the bracket. Cooperating with the setting of the liquid tank 7, it is possible to maintain smooth transportation of the liquid or gas when the main shaft 31 rotates, so as to achieve the effect of using the distributor to output feed or discharge air.

[0039] Example 3: Figure 2-4 As shown, the structure in Example 1 is embodied, the distributor includes a fixed rod 72, a movable rod 73 and an arc rod 74, the fixed rod 72 is fixedly connected to the lower end of the main shaft 31, and a movable groove 75 running through the middle of the fixed rod 72 is opened, the movable rod 73 is elastically slidably arranged in the movable groove 75 and extends outward in a static state, the arc rod 74 is connected to the end of the movable rod 73 and is concentric with the main shaft 31, a plurality of one-way valves 76 are evenly arranged on the upper end of the movable rod 73 along the length direction, the fixed rod 72 is opened with a secondary groove 77 connected to the liquid tank 7, and the movable rod 73 connects the plurality of one-way valves 76 through a second hose 78 and connects to the secondary groove 77.

[0040] The fixed rod 72 is used to install and connect the movable rod 73. The movable rod 73 is elastically slidably connected to the movable groove 75 of the fixed rod 72 and remains in an extended state in the initial state. The elastic sliding connection can adopt a connection method such as a spring. At the same time, in order to prevent the fry from entering the gap of the spring, the sliding connection part of the movable rod 73 and the fixed rod 72 can also use a corrugated cover to cover the opening area without affecting the movement of the movable rod 73. The setting of the arc rod 74 can enable the movable rod 73 to move with the main shaft 31. When the movable rod 73 is about to abut against the inner wall of the seedling pond 1, it plays a guiding and buffering role, ensuring that the movable rod 73 can cooperate with the arc rod 74 to abut against the inner wall of the seedling pond 1 to produce a telescopic effect. This method can increase the coverage area of ​​the feed or air output by the one-way valve 76, improve the effect of feeding the feed and the effect of supplementing oxygen.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made 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.
