Description

Technical Field

[0001] The utility model relates to the technical field of lobster seed screening devices, in particular to a lobster seed screening device for culturing crayfish in rice fields. Background Art

[0002] When breeding crayfish, it is necessary to use corresponding screening devices to screen the shrimp fry in order to select shrimp fry with similar individual sizes, so as to facilitate unified breeding by breeders.

[0003] A Chinese utility model patent with announcement number CN216254761U discloses a shrimp fry screening device for breeding crayfish in rice fields. The device can quickly screen the shrimp fry through its own mechanism, and can prompt the shrimp fry on the sieve plate to pass through the sieve holes of the sieve plate, thereby effectively improving the screening efficiency of the shrimp fry, and can put the shrimp fry inside the screening device in a moving state to avoid the shrimp fry inside the screening device from pinching each other, with fast screening efficiency and high working performance.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that there are the following defects:

[0005] The above device cannot effectively grade and screen the shrimp fry when screening the shrimp fry, so that the size of the selected shrimp fry is not uniform enough, so manual re-selection is required later, which increases the operation steps and reduces the screening efficiency.

[0006] Therefore, there is an urgent need for a shrimp seed screening device for rice field culture crayfish to solve the above-mentioned problems. Summary of the invention

[0007] In order to solve the technical problem that the above-mentioned device cannot perform classification and screening according to individual sizes well during screening, and thus manual sorting is required later, resulting in low screening efficiency, the utility model provides a shrimp seed screening device for rice field cultured crayfish.

[0008] The utility model adopts the following technical scheme to achieve: a shrimp seed screening device for rice field culture of crayfish, comprising:

[0009] A frame body, wherein the top and sides of the frame body are both opened;

[0010] A connecting side plate, wherein the connecting side plate is horizontally slidably arranged in the frame body, and the connecting side plate is arranged in multiple layers for multi-stage screening;

[0011] A toggle mechanism, which is arranged in the connecting side plate and matches the number of layers of the connecting side plate, so as to be used for reciprocating fluctuation to accelerate the screening of shrimp fry;

[0012] The elastic mechanism is arranged at the frame body to drive the connecting side plate to perform reciprocating horizontal motion.

[0013] Through the above technical solution, the elastic mechanism is used to realize the reciprocating movement of the shrimp fry connected to the inside of the side plate, and under the action of the internal toggle mechanism, the shrimp fry are accelerated to enter the leaking holes, so that the shrimp fry that meet the conditions enter the corresponding layer and are finally collected uniformly.

[0014] As a further improvement of the above scheme, leakage holes are evenly opened in the connecting side plates, and the diameter of each group of leakage holes decreases from top to bottom, wherein no leakage holes are opened at the bottom of the connecting side plates, and baffles are inserted and connected to the corresponding layers on the outside of the connecting side plates for blocking and discharging shrimp fry.

[0015] Through the above technical solution, the baffle can effectively block the side of the connecting side plate, thereby preventing the shrimp seedlings from going out during screening. After the screening is completed, the baffles can be taken out one by one to quickly take out the shrimp seedlings.

[0016] As a further improvement of the above scheme, the toggle mechanism includes a driving motor 2 and a belt, and the driving motor 2 is installed on the other side of the connecting side plate. The belt is sequentially provided with a belt pulley 1, a belt pulley 2 and a belt pulley 3 from bottom to top, wherein the belt pulley 1 is connected to the output shaft of the driving motor 2, and the diameter of the belt pulley 2 is larger than that of the belt pulley 1 and the belt pulley 3, and the inner sides of the belt pulley 1, the belt pulley 1 and the belt pulley 3 are all connected with connecting components.

[0017] Through the above technical solution, the second belt pulley is located in the middle to effectively ensure the realization of transmission.

[0018] As a further improvement of the above scheme, the connecting component includes a rotating shaft rotatably connected to the connecting side plate, the outer wall of the rotating shaft is evenly provided with circulation grooves, the circulation groove is slidably connected to a connecting plate, the connecting plate is horizontally slidably connected to the connecting side plate, both sides of the bottom end of the connecting plate are connected with adjustment slots, and an abutment push plate is rotatably connected in the adjustment slot for pushing the shrimp seedlings into the leaking eye.

[0019] Through the above technical solution, the rotation of the rotating shaft can realize the horizontal reciprocating movement of the connecting plate in the connecting side plate under the sliding connection between the circulation groove and the connecting plate.

[0020] As a further improvement of the above solution, the elastic mechanism includes springs symmetrically connected to one side of the connecting side plate, and the other sides of the two groups of springs are connected to the inner wall of the frame body.

[0021] As a further improvement of the above scheme, the elastic mechanism also includes a driving motor installed on the outside of the frame body, the top of the driving motor is connected to a cam, and the outer tread of the cam is connected to the outer bottom end of the connecting side plate to drive the connecting side plate to slide.

[0022] Through the above technical solution, a driving motor drives the cam to cooperate with the elasticity of the spring to perform reciprocating repeated motion.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (I) The utility model utilizes a toggle mechanism disposed in the connecting side plate. After the shrimp fry are placed in, the toggle mechanism can be used to push the shrimp fry inside back and forth, so that the shrimp fry that meet the conditions can quickly enter the corresponding stratification area, effectively ensuring the uniformity of the individual size of the shrimp fry after stratification, which is convenient for later cultivation.

[0025] (ii) The utility model utilizes an elastic mechanism in conjunction with a toggle mechanism to more quickly screen the shrimp seedlings, and can effectively reduce the shrimp seedlings from being clamped together under the shaking and toggling effects, thereby improving the efficiency of shrimp seedling screening.
