[0002] In recent years, with more and more artificially farmed fish species, how to study their reproductive capacity and then guide aquaculture production, accurately expand the scale of breeding, and reduce the cost of broodstock is an indispensable link in improving aquaculture production capacity. In the process of aquaculture and fish reproductive capacity research, it is often necessary to conduct statistics on spawning volume and fertilization rate, which is a key link, and can provide data support for fish reproductive capacity research and improving aquaculture production. At present, the commonly used methods for counting fish eggs are mainly manual method, scale method and weighing method. The manual method uses culture dishes, plastic plates, enamel basins to manually count fish eggs, or uses small measuring tools with fixed volume such as bowls and cups to count according to the number of scooping times. This method has large errors, low efficiency, and may cause damage to the fish eggs; the scale method is to count fish eggs with a dial and a counting box. Although it improves work efficiency to a certain extent, the error is large; the weighing method is to directly weigh the weight of the ovaries or the total weight of the fish eggs, and then weigh the weight of a single egg multiple times to take the average value to achieve counting. These methods have large errors, low efficiency and the risk of damaging fish eggs to a certain extent.

DETAILED DESCRIPTION

[0018] Example 1 like Figures 1 to 6 As shown, an automatic fish egg counting device is provided, a sealing end cover 5 is provided at the top of the fish egg placing bucket 4 near the mouth, one side of the fish egg placing bucket 4 is connected with the second water tank 9 through a closed pipe 10, a second electric valve 11 is provided on the closed pipe 10, an outlet of a long strip shrinking structure is provided at the lower end of the fish egg placing bucket 4, a draw-out valve 13 is provided at the outlet position, an inclined counting belt 14 is also provided at the outlet at the lower end of the fish egg placing bucket 4, the counting belt 14 is provided with a body permeable material, an industrial camera 18 is provided above the counting belt 14, an inclined blanking trough 17 is provided above the counting belt 14, a plurality of nozzle groups are provided between the blanking trough 17 and the counting belt 14, and the nozzle groups are directed to the top of the counting belt 14 or / and to the direction of the blanking trough 17.

[0019] The fish egg placing bucket 4 is used to store the fish eggs and water to be counted. The sealing end cover 5 is installed on the top of the fish egg placing bucket 4 to seal the fish egg placing bucket. The closed pipe 10 connects the fish egg placing bucket 4 and the second water tank 9. The second electric valve 11 is installed on the closed pipe 10 to control the water flow. The draw plate valve 13 is installed at the lower end outlet of the fish egg placing bucket 4 to control the release of the fish eggs. The counting belt 14 is tilted and made of permeable material. It is used to transport fish eggs and count them through an industrial camera. The industrial camera 18 is installed above the counting belt 14 to take images of fish eggs. The drop chute 17 is tilted and located above the counting belt 14 to guide the fish eggs to slide onto the counting belt. The nozzle group is located between the drop chute 17 and the counting belt 14 to clean the counting belt 14 and the fish eggs.

[0020] Preparation stage: fish eggs and water are poured into the fish eggs placement bucket 4 inside, at this moment, the draw plate valve 13 is in a closed state, and the sealing end cover 5 is covered, so that the fish eggs are placed in the bucket 4 inside in a closed state.

[0021] Startup phase: open the plate-drawing valve 13 and keep it in the open state until the fish egg detection is completed. Open the second electric valve 11 and inject water into the fish egg placement bucket 4 through the closed pipeline 10. The pressure change inside the fish egg placement bucket 4 causes the fish eggs to begin to fall through the plate-drawing valve 13. At the same time, start the counting belt 14 to rotate.

[0022] Counting stage: the fish eggs fall onto the counting belt 14, which is made of water-permeable material, so that water and fish eggs are separated on the counting belt. The industrial camera 18 takes pictures of the fish eggs on the counting belt 14.

[0023] Pause stage: when it is necessary to pause or complete the counting, the second electric valve 11 is closed, and the closed pipe 10 stops injecting water into the fish egg placement bucket 4. Since the drawer valve 13 is always in an open state, the sealed state inside the fish egg placement bucket 4 is maintained by the opening and closing of the second electric valve 11. After closing the second electric valve 11, there is no airflow inside the fish egg placement bucket 4 and it is in a closed state. The shrinkage design of the lower end of the fish egg placement bucket 4 is 4-6mm, which is mentioned as 4mm in this example, so the outlet at the lower end of the fish egg placement bucket 4 will not continue to discharge fish eggs and water.

[0024] Preparation stage again: after all the fish eggs have been counted by the counting belt 14, the drawer valve 13 is closed.

[0025] The design of the 4mm shrinkage ensures that there is no fluidity when the top of the fish egg placing bucket 4 is in a closed state, and the shrinkage below the fish egg placing bucket 4 will not flow out water and fish eggs. At the same time, the shrinkage design is small, which can prevent the occurrence of air leakage.

[0026] Through the above steps, a sealed environment is formed inside the fish egg placing bucket 4 by opening and closing the second electric valve 11 to control the flow of the fish eggs, and the drawer valve 13 is only closed at the end of the whole process to ensure that the fish eggs can flow out of the fish egg placing bucket 4 smoothly and be counted on the counting belt 14.

[0027] in: In the preparatory stage, the plate-drawing valve 13 is in the closed state, so that fish eggs and water are poured into the fish eggs and placed in the bucket 4. Before starting to count, open the plate-drawing valve 13 so that it remains in the open state until the fish eggs have been detected.

[0028] When the fish eggs fall, the draw plate valve 13 remains in an open state. The outflow and stop of the fish eggs completely depend on the opening and closing of the second electric valve 11. When the fish eggs are detected, the draw plate valve 13 is closed. The sealing condition inside the fish egg placement bucket 4 is mainly achieved by the opening and closing of the second electric valve 11. When the second electric valve 11 is closed, the inside of the fish egg placement bucket 4 forms a sealed state.

[0029] In the preferred embodiment, a card slot is provided on the sealing end cover 5, a sealing gasket is provided inside the card slot, and the card slot of the sealing end cover 5 is clamped in the outer ring of the fish egg placement bucket 4 to form a seal. A sealing gasket is provided inside the card slot of the sealing end cover 5, and a good sealing effect is formed by clamping the card slot of the sealing end cover 5 in the outer ring of the fish egg placement bucket 4. The card slot on the sealing end cover 5 is combined with the outer ring of the fish egg placement bucket 4, and the effect of the sealing gasket ensures a better sealing effect. It is also convenient to install and disassemble.

[0030] It ensures that the inside of the fish roe placing bucket 4 can form a sealed state when needed, and at the same time controls the outflow and stops the outflow of the fish roe. The special design of the sealing end cover 5 further enhances the overall sealing performance.

[0031] In the preferred embodiment, the second water tank 9 is connected to the second electric valve 11 through the second water pump 901 , and the second electric valve 11 is connected to the upper position of the fish egg placement bucket 4 through the closed pipe 10 .

Since the shrinkage at the lower end of the fish egg placement bucket (4) is 4-6 mm, the outlet at the lower end of the fish egg placement bucket (4) will not discharge fish eggs and water; S5, the industrial camera (18) takes a picture of the counting belt (14), and after taking the picture, the fish eggs are processed by viewing angle, and the number of fish eggs on the counting belt (14) is obtained by analysis and displayed on the display screen (2). After the picture is taken, the counting belt (14) starts to rotate, and the above steps S2-S3 are repeated; S6, when the counting belt (14) rotates to the lower position, the first nozzle group (15) and the second nozzle group (16) start to flush the fish eggs on the lower surface of the counting belt (14) to prevent the fish eggs from adhering to the bottom of the counting belt (14). The flushed fish eggs and water fall onto the drop trough (17), and the downward nozzles of the first nozzle group (15) flush the fish eggs on the drop trough (17) to the position of the outlet trough (3), thereby completing the counting of the fish eggs.
