Description

Technical Field

[0001] This utility model relates to the field of counting randomly distributed items, and specifically to a fish fry counting device. Background Technology

[0002] Chinese patent CN221749380U discloses a fish fry counting device, including a housing with a water collection tank inside. A net basket is attached to the water collection tank, and a circulation pump is installed inside the tank. The outlet of the circulation pump is connected to a flexible hose, and the other end of the hose is connected to a water pipe. The end of the water pipe extends to the top of the water tank. After counting is completed, the fish fry fall into the net basket, and the water enters the water collection tank, thus achieving water recycling. The light source plate illuminates the fish fry passing through tempered glass, enabling the counting system to identify and capture them. However, because the water pipe is in a fixed position, it is impossible to transport fish fry in different locations within the water tank in a timely manner, thus reducing the counting efficiency and making it impractical. Utility Model Content

[0003] The purpose of this invention is to provide a fish fry counting device that circulates water into the fish fry release tank through a back-and-forth oscillating nozzle, so that fish fry in different positions in the release tank can be transported in a timely and directional manner, thereby improving the efficiency of fish fry counting and saving time.

[0016] Example 1:

[0017] See Figures 1 to 5A fish fry counting device includes a housing 101. A fish fry feeding trough 102 is located at the top of the housing 101. A counting channel 104 is located below the fish fry feeding trough 102. The outlet of the fish fry feeding trough 102 is connected to the inlet of the counting channel 104. A counting component 103 is located above the counting channel 104. A collection trough 120 is located below the outlet of the counting channel 104. A net basket is attached to the top of the collection trough 120. A circulation pump 105 is located at the bottom of the collection trough 120. One end of the circulation pump 105 is connected to a circulation pipe 106. The other end of the circulation pipe 106 extends above the fish fry feeding trough 102. A U-shaped bracket 108 is provided on one side of the trough 102. A motor 124 is provided on one bracket plate of the U-shaped bracket 108. A crank disc 113 is fixed on the output shaft 112 of the motor 124. A crank pin 114 is provided on the surface of the crank disc 113. A rotating rod 111 is provided on the other bracket plate of the U-shaped bracket 108. A rocker arm 109 is provided at one end of the rotating rod 111. A dial hole 123 is provided on the rocker arm 109. The crank pin 114 is connected to the dial hole 123. A swing ring 110 is provided at the other end of the rotating rod 111. A nozzle 107 is movably connected to the other end of the circulation pipe 106. The swing ring 110 is sleeved on the nozzle 107.

[0018] See Figure 1 In this embodiment, the four feet of the chassis 101 are equipped with casters, which have locking mechanisms, and the casters facilitate the movement of the entire device.

[0019] In this embodiment, the counting component 103 is fixed to the top inner side of the chassis 101 and includes multiple CCD cameras arranged in a rectangular array. The image data collected by the CCD cameras is transmitted to the processor for analysis and processing to count the number of fish fry, and the results are transmitted to the display screen for display. The counting component 103 falls within the scope of existing technology.

[0020] In this embodiment, the nozzle 107 is located on the side away from the outlet of the fish fry release tank 102, and the nozzle 107 is connected to the circulation pipeline 106 via a flexible hose or corrugated pipe. The circulation pipeline 106 can be a metal pipe or a plastic pipe, and the nozzle 107 can be made of metal or rigid plastic. The nozzle 107 and the circulation pipeline 106 are connected by a flexible and deformable pipe section, allowing the nozzle 107 to swing within a certain range.

[0021] When this device is in operation, fish fry are first introduced into the fish fry release tank 102. The motor 124 is then started, driving the crank disc 113 to rotate clockwise or counterclockwise. The swing arm 109 swings along with the crank disc 113. When the crank disc 113 rotates to 90 degrees, the swing arm 109 deflects to one side to its maximum angle. When the crank disc 113 rotates to 180 degrees, the swing arm 109 returns to its original position. When the crank disc 113 rotates to 270 degrees, the swing arm 109 deflects to the other side to its maximum angle. When the crank disc 113 rotates to 360 degrees, the swing arm 109 returns to its original position. The swing ring 110 moves synchronously with the swing arm 109, thereby causing the nozzle 107 to swing left and right. This allows the nozzle to sweep and flush the fish fry to different positions within the release tank, achieving uniform flushing and dispersion of the fish fry, improving the efficiency of fish fry counting, and saving time.

[0022] Fish fry enter the counting channel 104 with the water flow. The counting channel 104 guides the fish fry. The counting component 103 counts the fish fry passing below it. After counting is completed, the fish fry fall into the net basket for temporary storage, realizing the interception of fish fry and the filtration of water. Water falls into the collection tank 120 through the mesh of the net basket. The circulation pump 105 can realize water recycling and realize non-stop operation.

[0023] The fish fry counting device in this embodiment can be improved based on the prior art. For the same technical content as the prior art, it can be understood by referring to the technical content disclosed in the prior art.

[0024] See Figure 1 , Figure 3 , Figure 4 In this embodiment, the inlet of the counting channel 104 is equipped with a surging impeller 119. The surging impeller 119 is mounted to the housing 101 via an impeller shaft 118. A driven pulley 116 is fixed to one end of the impeller shaft 118 extending out of the housing 101. A driving pulley 115 is fixed to the output shaft 112 of the motor 124. The driven pulley 116 is connected to the driving pulley 115 via a belt 117. The surging impeller 119 is linked with the oscillating nozzle 107 to agitate the water flow and prevent fish fry from accumulating. The inclination angle of the counting channel 104 is very small, which improves the survival rate of fish fry during transportation.

[0025] See Figure 5 In this embodiment, the outlet of the fry release trough 102 is connected to the inlet of the counting channel 104 through a U-shaped cavity 122. The U-shaped cavity 122 can buffer the drop between the fry release trough 102 and the counting channel 104, reducing the impact on the fry.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of this utility model, and should all be covered within the scope of the claims of this utility model.
