Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a proliferation and release classification counting device and method. Background Art

[0002] In the field of fishery management and stocking, counting and statistics of seedlings are important bases for evaluating the effect of stocking, monitoring population dynamics and formulating fishery policies. However, traditional seedling counting methods mainly rely on manual operations, which are not only time-consuming and laborious, but also easily affected by human factors such as fatigue and distraction, resulting in large counting errors and low efficiency. At the same time, the mortality rate of fry will also increase during manual handling, further affecting the effectiveness of stocking activities. Therefore, the development of a device that can automatically, accurately and efficiently complete the task of seedling counting has become a key issue that needs to be solved in this technical field.

[0003] In order to solve the above problems, some attempts at automatic counting devices have appeared in the prior art, but most of them have problems such as complex design, inconvenient operation or insufficient counting accuracy. For example, some devices use image recognition technology, but the fry are small in size, move fast, and are stacked up and down, front and back, so there are problems such as missing counts and repeated counts, resulting in large counting errors. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the field of fish fry proliferation and release, the counting of fish fry relies on manual labor, which is time-consuming and labor-intensive, has large counting errors, and the mortality rate of fish fry will also increase during manual processing. A proliferation and release classification counting device and method are provided, which can accurately count the fish fry by driving and inducing the fish fry to transfer and divert them in different breeding areas, and classify the fish fry according to their body size to separate the fish fry of different sizes.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a proliferation and release classification counting device, comprising an initial fish pond, a large fish pond is arranged outside the initial fish pond, the large fish pond is divided into a first fish pond and a second fish pond independent of each other by a partition, the partitions are respectively the first partition and the second partition on both sides of the initial fish pond, a counting channel is arranged on the side of the initial fish pond facing the second partition, and the second partition is arranged in the center at the end of the counting channel; the counting channel is sequentially provided with a rotating flap, a classification touch plate, and a swinging guide plate from front to back; the rotating flap is evenly arranged around a rotating shaft Multiple blade plates are evenly arranged, and the rotating flap is driven by a stepper motor; two classification touch plates are symmetrically arranged, and the two classification touch plates are in an eight-shaped shape that is wide in front and narrow in the back and can be opened and closed, the front ends of the two classification touch plates are hinged shafts, and the rear ends are swing ends, the hinge shafts of the classification touch plates are provided with torsion springs, and the upper ends of the classification touch plates are provided with touch switches; two swing guide plates are arranged, and the two swing guide plates are parallel to each other and swing synchronously, the front ends of the swing guide plates are swing shafts, the rear end of one of the swing guide plates abuts against the front end of the second partition, and counting sensors are respectively provided on both sides of the second partition.

[0006] In this device, for the fry that need to be proliferated and released, they need to be transferred from the initial fish pond to the large fish pond. During the transfer of the fry, this device sets a counting channel to drive the fry into the counting channel one by one, and guides and diverts the fry according to their body size to different areas of the large fish pond to avoid fry with large size differences being raised together, resulting in injuries to the small fry. The counting process of this device is completed automatically without manual operation, with high counting accuracy and little damage to the fry. In addition, the fry are diverted according to their body size during the counting process, which is more conducive to increasing the survival rate of the fry in the subsequent breeding process.

[0007] Preferably, the two swing guide plates are synchronously controlled by two synchronous motors, or the two swing guide plates are controlled by one motor in conjunction with a synchronous belt or synchronous gear. The swing of the swing guide plate can guide the fry into different breeding areas according to their body shapes, and the swing direction of the swing guide plate is controlled by a signal of a classification touch plate.

[0008] Preferably, a cover plate is provided on the top surface of the counting channel, and the synchronous motor, stepper motor and touch switch are all arranged above the cover plate.

[0009] Preferably, a flexible roller is arranged at the rear end of the classification touch plate, and the surface of the flexible roller is made of silicone material. The rear end of the classification touch plate contacts the fish body through the flexible roller, thereby reducing damage to the fish body.

[0010] Preferably, the width of the counting channel at the rotating flap is greater than the width of a single fry and less than the width of two fry.

[0015] A method for classification and counting of proliferation and release, using the above-mentioned device, comprises the following steps: S1, initial state, the fry are cultured in the initial fish pond; S2, the initial state of the swinging guide plate is toward the second fish pond. When the fish need to be proliferated and released, the rotating flap starts to rotate step by step, so that the fry enter the counting channel one by one. After the fry pass through the rotating flap, they pass through the classification touch plate. If the touch switches of the classification touch plates on both sides have no signal or only the touch switch of the classification touch plate on one side receives a touch signal, the swinging guide plate maintains the initial state, and the fry is a small fry and enters the second fish pond through the swinging guide plate, and the second partition counts toward the counter of the second fish pond; if the touch switches of the classification touch plates on both sides receive a touch signal, the swinging guide plate swings toward the first fish pond, and the fry is a large fry and enters the first fish pond through the swinging guide plate, and the second partition counts toward the counter of the first fish pond. After the counting is completed, the swinging guide plate automatically swings to the initial state; S3, the first driving mesh plate and the second driving mesh plate are initially positioned toward the first partition plate, and when no new fry enters the rotating flap for a long time, the fry are driven toward the second partition plate by manual traction or motor-driven reverse rotation, so that the fry enter the counting channel; S4, until the first driving mesh plate and the second driving mesh plate rotate to the side facing the counting channel, manually verify the remaining fry in the initial fish pond to confirm that all the fry have entered the first fish pond and the second fish pond.

A counting channel 15 is arranged on the side of the initial fish pond 1 facing the second partition 7, and the second partition 7 is arranged in the center at the end of the counting channel 15. Figure 1 , 3 As shown, a double-layer rotating shaft 14 is arranged at the center of the initial fish pond 1. The rotating directions of the double-layer rotating shaft are opposite. The double-layer rotating shaft is respectively connected to a first driving mesh plate 5 and a second driving mesh plate 6 with opposite rotating directions.

[0025] like Figure 4As shown, the counting channel 15 is provided with a rotating flap 8, a classification touch plate 10, and a swinging guide plate 11 from front to back. The rotating flap 8 is evenly provided with a plurality of blade plates around the rotating shaft, and the rotating flap 8 is driven by a stepping motor 9 belt. The width of the counting channel at the rotating flap 8 is greater than the width of a single fry and less than the width of two fry.

A fry sensor can be provided on one side of the rotating flap 8 of the counting channel to detect whether there are fry entering when the rotating flap 8 rotates. If there are fry entering, the rotating flap 8 will pause and wait for the fry to pass through the counting channel and then continue to rotate. If there are no fry entering, the rotating flap 8 will rotate continuously.

[0026] The two classification touch panels 10 are symmetrically arranged, and the two classification touch panels are in an eight-shaped arrangement with a width at the front and a narrowness at the back, and can be opened and closed. The front ends of the two classification touch panels are hinged shafts, and the rear ends are swing ends. The hinged shafts of the classification touch panels are provided with torsion springs 19 for resetting, and the upper ends of the classification touch panels are provided with touch switches 16. The rear ends of the classification touch panels 10 are provided with flexible rollers 18, and the surface of the flexible rollers is made of silicone material.
