The angle is adjusted, and in conjunction with the rotation of the gear ring 13 and the telescopic adjustment of the push rod motor 14, the fish in the identification box 3 can be identified and measured within a multi-angle range.

The linkage mechanism includes a baffle 182, which is arranged at one end of the square rod 181, and the sliding sleeves running through both sides of the baffle 182 are provided with sliding rods 183. The sliding rods 183 are fixedly connected to spline grooves 184 on both sides of the baffle 182. With the first rotating seat 185, and the second spring 186 is set on the sliding rod 183, the square rod 181 is also fixedly connected with the guide block 187, so that the sliding rod 183 can be slid through the baffle 182, and The spline groove 184 is driven to move left and right to facilitate the setting of the clamping position in cooperation with the spline 173.

The adjustment mechanism includes a second rotating seat 191, which is located at one end of the square sleeve 19 close to the first rotating seat 185. The square sleeve 19 is also provided with a chute 192 and is slidably sleeved on the guide block 187. The square sleeve There is a rotating plate 193 rotatably connected between 19 and the flat frame 202. The flat frame 202 is also provided with an inclined block 194 that is slidingly connected to the second rotating seat 191. In this way, when necessary, the electric cylinder 9 can be controlled to expand and contract to drive the supporting plate. 10 moves upward, and then drives the frame 16, the flat plate 161 and the rotating roller 162 to move upward until it conflicts with the lower end surface of the flat frame 202, driving it to move upward. The flat frame 202 will squeeze the rotating plate 193 to rotate, and the pushing direction The sleeve 19 slides toward the identification box 3 side, and at the same time, the rack 203 moves upward, and also drives the second gear 171 to rotate.

The guide mechanism includes a limit chute 20 and an electric chute 21, and the upper and lower right ones are respectively installed on the square sleeve 19. A plurality of limit slide blocks 2001 are slidably provided in the limit chute 20, and each limit The guide plates 2002 are fixedly connected to the slide blocks 2001, and the adjacent side surfaces of the adjacent guide plates 2002 are provided with rotating blades 2003.

The supporting plate 10 is located above the water storage tank 1, the frame 16 is arranged on the outside of each connecting slide 2, and the identification and measurement ring 12 is set on the outside of the identification box 3 and between the connecting slides 2 on both sides, so that When the electric slide rail 7 is used to adjust the electric slide block 8 to slide, so that the support plate 10 moves left and right, the frame 16 will also move. Since the rotating roller 162 is provided on the flat plate 161 of the frame 16 to contact the flat frame 202, the frame 16 will move. The adjustment of the body 16 sliding left and right will not change the state of the flat frame 202 through the contact between the rotating rod 162 and the flat frame 202.

The square rods 181 on the front and rear sides are located inside the width direction of the identification box 3 and close to the inner wall of the identification box 3. The spline groove 184 is on the side close to the spline 173, and is matched with the ferrule, so that the electric cylinder 9 drives the frame. 16. When the flat frame 202 moves upward, driving the rotating plate 193 to rotate, and pushing the square sleeve 19 to slide above the identification box 3, the square sleeve 19 will be just above and inside the identification box 3, and close to the identification box 3 inner wall.

The first rotating base 185 and the second rotating base 191 both have a fixed inner ring on the inside, and an outer ring is rotated on the outside, and the inner inner ring is fixed on the respective components, so that on the flat frame 202 After moving to a certain extent, the inclined block 194 on it will resist the first rotating seat 185, and push the spline groove 184 and the spline 173 to lock. During the locking process, there may be a situation where the spline groove cannot be aligned in time, so the spline groove 184 will first compress the spline 173 so that it overcomes the elastic force of the first spring 174 and slides into the limiting sleeve 172 until it is aligned with the spline groove 184 and then ejected and locked with the spline groove 184. In this way As the upward movement proceeds, the second gear 171 continues to rotate, which will drive the square rod 181 and the square sleeve 19 to rotate, and the guide plate 2002 on the sleeve 19 in front of the rotation will be in the vertical direction of the identification box 3 inside to prevent the guide plate 2002 from colliding with the frame of the identification box 3 .

The limiting chute 20 and the square sleeves 19 provided on the front and rear sides of the electric chute 1 are close to each other, so that each guide plate 2002 will be in a horizontal state when not in use, and will gradually rotate to vertical when in use. In the straight state, during this transformation process, the live fish in the identification box will be limited to the front and rear sides, and the outer shell of the identification box will fit more clearly and intuitively when the identification box uses transparent materials. To identify and measure fish, a scale can also be set on the side of the transparent identification box 3 so that the size of live fish can be more intuitively read, and dead fish can be identified and measured in the same way.

The rotational connections of the rotor 2003 are all connected through spring hinges, which ensures that before the square sleeve 19 rotates, the electric chute 21 is controlled to drive the electric limit slide 2101 to start sliding, and through the setting of the spring hinge, it is ensured that Each rotor 2003 can rotate and unfold evenly to ensure that the swimming direction of the fish is restricted and blocked, so that it can only move to both sides, and the square sleeves 19 on the left and right sides are close to each other and the distance between the near ends is normal. 5-10cm, and the distance between the guide plate 2002 and the inner wall closest to the width direction of the identification box 3 is 3-6cm, to prevent the spline 173 and the Chinese key groove 184 from not being able to cooperate in time, and the square sleeve 9 can still move to a certain extent. The stroke is redundant, and within the redundant range, when the guide plate 2002 is driven to rotate by the square sleeve 9, it will not conflict with the side frame of the identification box 3.

Example 2:

Based on the first embodiment, the water pipes 6 on both sides can also be connected to the identification box 3 respectively, so that transportation can be carried out through the water pipes 6. During the identification and measurement, the mesh plates 4 on both sides are threaded and removed when changing fish. The mesh plate 4 can achieve efficient measurement of a large number of fish, and the specific transportation can be carried out by setting the identification box 3 at a low place, and setting one end of the water supply pipe 6 at a high place, and conveying by gravity, or The water pump is connected for transmission, but is not limited to these two methods. For the specific identification operation, the operation method is the same as that of Embodiment 1. This can improve the high throughput in the identification measurement process and improve the efficiency of identification measurement.
