Description

Technical Field

[0001] The utility model relates to the technical field of shrimp farming, in particular to a seedling separation device for shrimp farming. Background Art

[0002] In shrimp farming, in order to improve the survival rate of seedlings, shorten the breeding cycle, and scientifically release the seedlings, the shrimp seedlings need to be thickened. When the thickening reaches a certain time and specification (for example, after about 20 days of thickening, the shrimp seedlings can reach 2000-3000 per catty), the shrimp seedlings in the thickening pool will be divided into a larger space for fine cultivation. The above process is called seedling separation. However, traditional seedling separation usually relies on manual operation, which is inefficient and easily affected by human factors, resulting in inaccurate seedling separation results. In addition, manual seedling separation is also easy to cause damage to the shrimp, affecting its quality. Utility Model Content

[0029] The utility model is described in detail below in conjunction with the accompanying drawings.

[0030] See also Figure 1-3 The present embodiment provides a seedling separation device for shrimp farming, which includes a conveying mechanism 1, a support frame for supporting the conveying mechanism 1, a net cage 2 installed on the conveying mechanism 1, a cleaning component 3 for spraying water to the net cage 2, a light shield 4, a seedling separation shell 5 with a weighing space and a seedling receiving space, a weighing platform 7 composed of a horizontally arranged platform body I and a platform body II, a flow guide cover 6 for connecting the conveying mechanism 1 and the weighing platform 7, a gravity sensor 8 installed on the weighing platform 7, an opening and closing control mechanism 9 acting on the weighing platform 7, and a shrimp collecting tank 10 located below the weighing platform 7.

[0031] The conveying mechanism 1 is arranged obliquely downward on one side facing the seedling separation housing 5, and the conveying mechanism 1 includes a frame, a plurality of transmission rollers rotatably mounted on the frame, a conveyor belt installed between the plurality of transmission rollers, and a driving motor for driving one of the transmission rollers to rotate. The plurality of transmission rollers are arranged horizontally, and a belt pulley is fixedly mounted on the transmission roller, and a belt is meshed between the belt pulleys on the same side. In this embodiment, the plurality of transmission rollers rotate in the same direction based on the cooperation of the belt pulley and the belt, thereby realizing the directional movement of the conveyor belt to transport the shrimps flushed out of the net cage 2 to the seedling separation housing 5 for seedling separation.

[0032] The net cage 2 is provided with a slot at the side wall corresponding to the feeding end of the conveying mechanism 1, which is used for passing the shrimp. The cleaning component 3 is composed of a nozzle and a water inlet pipe. The nozzle is mounted on the frame of the conveying mechanism 1 through a fixed frame, and the nozzle is located above the net cage 2. The light shield 4 is fixedly mounted on the frame of the conveying mechanism 1 through a cover frame. The light shield 4 is used to block light during the directional transmission of the shrimp, thereby reducing the stress response of the shrimp seedlings. At the same time, the shrimp is cleaned based on the cleaning component 3, and the water flow is used to promote the shrimp to flow into the seedling separation housing 5.

[0033] The seedling separation housing 5 is located at the discharge end of the conveying mechanism 1, and the weighing space is located above the seedling grafting space. The weighing platform 7 is installed between the weighing space and the seedling grafting space. The air guide hood 6 is located in the weighing space, and the feed port of the air guide hood 6 is fixedly installed on the corresponding side wall of the conveying mechanism 1, and the discharge port of the air guide hood 6 is arranged close to the weighing platform 7.

[0034] The gravity sensor 8 is embedded in the platform I, and the opening and closing control mechanism 9 includes two groups of rotating shafts and motors for driving the corresponding rotating shafts to rotate. One group of rotating shafts is fixedly installed on the side of the platform I facing away from the platform II, and the remaining group of rotating shafts is fixedly installed on the side of the platform II facing away from the platform I. The platform I and the platform II perform opening and closing movements under the action of the opening and closing control mechanism 9. When in the weighing and seedling separation stage, the platform I and the platform II are in a closed state, and the shrimps sent in through the guide cover 6 fall on the weighing platform 7 for weighing. When the weight weighed by the gravity sensor 8 reaches the set value, the opening and closing control mechanism 9 is opened. At this time, the two groups of motors rotate in the opposite direction, the platform I and the platform II open downward, and the shrimps pass through and fall into the shrimp collection tank 10, and are then put into the new breeding pond for fine cultivation. After the shrimps are unloaded, the platform I and the platform II are closed by the opening and closing control mechanism 9 for subsequent seedling separation.

[0035] In summary, the seedling separation device of this embodiment has the following advantages: it adopts a non-contact detection method to weigh the coarse shrimp seedlings, and directly weighs and collects them to obtain the amount of shrimp seedlings to be transferred to the new breeding pond, avoiding the damage caused by artificial seedling separation and ensuring the quality of the shrimp.
