AI Technical Summary
Existing juvenile turtle screening devices tend to cause juvenile turtles to pile up, resulting in smaller, less healthy juvenile turtles being mixed in. Furthermore, juvenile turtles are easily injured by friction against the screen during the screening process.
Water is sprayed onto the juvenile turtles using nozzles to reduce stacking and to reduce friction between the turtles and the screen through the lubrication of the water flow. The adjustable spray direction and height ensure that each turtle passes through the screen holes individually, and the use of soft bristles reduces friction damage.
It effectively reduces the probability of injury to juvenile turtles, reduces sieve hole wear, and improves screening efficiency, reducing the injury rate of juvenile turtles from 15% to below 4%.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of juvenile soft-shelled turtle screening equipment, and in particular to a screening device for juvenile Chinese soft-shelled turtles. Background Technology
[0002] After hatching, Chinese softshell turtles exhibit differences in size and physical strength due to factors such as genetics and hatching conditions. Mixed rearing can easily lead to stronger turtles competing for food and weaker turtles experiencing stunted growth. Therefore, after hatching, it is necessary to screen the juvenile turtles to adjust the feed particle size, feeding amount, and rearing environment (such as water level and density) for different sizes of juvenile turtles to ensure survival rate.
[0003] Existing methods for screening juvenile turtles using vibration screening devices to identify smaller juvenile turtles with poor physical condition are ineffective. However, during the screening process, the juvenile turtles tend to stack up on top of each other, resulting in the presence of smaller juvenile turtles with poor physical condition mixed in. In addition, the juvenile turtles are prone to injury due to wear and tear on the screen mesh as they move on it. Summary of the Invention
[0004] This disclosure relates to a screening device for juvenile Chinese soft-shelled turtles. The spray nozzle sprays water onto the juvenile turtles falling from the upper funnel, reducing the stacking of the juvenile turtles and making them more dispersed. At the same time, after spraying water, the lubrication effect of the water flow reduces the friction between the juvenile turtles and the upper screen frame and the middle vibrating screening frame, reducing the wear and injury of the juvenile turtles as they pass through the screen holes of the upper screen frame, and further reducing the probability of injury to the juvenile turtles during screening.
[0005] In a first aspect, this disclosure provides a screening device for juvenile Chinese soft-shelled turtles, specifically comprising: a middle vibrating screening frame, an upper screen frame, and a lower water collection box. The upper screen frame is fixedly connected to the upper part of the middle vibrating screening frame, and the lower water collection box is provided below the middle vibrating screening frame. External elastic buffers are fixedly provided on both sides of the middle vibrating screening frame. The middle part of the middle vibrating screening frame is provided with an array of permeable holes that extend through the interior and exterior. A vibrating motor is fixedly installed at the front of the middle vibrating screening frame.
[0006] In at least some embodiments, the lower end of the external elastic buffer is fixedly connected to the lower water collection box, and the middle vibration screening frame and the middle water permeable hole are both located above the inner side of the lower water collection box.
[0007] In at least some embodiments, side connecting slides are fixedly provided on both sides of the upper screen frame, and a first lifting screw is rotatably provided on the inner side of the side connecting slide on one side of the upper screen frame. The first lifting screw is threadedly connected to the tail end of the middle baffle. A middle transverse water pipe is rotatably provided on the front side of the middle baffle through a rotating shaft, and water nozzles are arranged in an array at intervals on the front part of the middle transverse water pipe.
[0008] In at least some embodiments, the first and last ends of the middle baffle are vertically slidably connected to the side connecting slide, and the middle part of the middle baffle is threadedly connected to a second lifting screw. The lower end of the second lifting screw is rotatably connected to a lower connecting rod via a rotating shaft. The tail end of the lower connecting rod is rotatably connected to the upper part of the middle transverse water pipe via a rotating shaft. The second lifting screw pushes the middle transverse water pipe to adjust its angle via the lower connecting rod. The middle transverse water pipe and the control spray nozzle are tilted and adjusted at the same angle to control the spray height and direction of the spray nozzle and to control the spray nozzle to disperse the juvenile turtles.
[0009] In at least some embodiments, an upper funnel is fixedly provided on the front side of the lower water collection box, and an internal pump is installed on the inner side of the lower water collection box.
[0010] In at least some embodiments, the internal pump and the central transverse water pipe are connected, with the central transverse water pipe located on the side of the central baffle near the upper funnel.
[0011] In at least some embodiments, the upper funnel is located above the front side of the upper screen frame, and the water spray nozzle is located on the side of the middle horizontal water pipe near the upper funnel. The water spray nozzle sprays water onto the juvenile turtles falling from the upper funnel, further reducing the stacking of juvenile turtles. At the same time, after spraying water, the friction between the juvenile turtles and the upper screen frame and the middle vibrating screen frame is reduced through the lubrication effect of the water flow.
[0012] This utility model provides a screening device for juvenile Chinese soft-shelled turtles, which has the following beneficial effects:
[0013] The spray nozzle sprays water onto the juvenile turtles falling from the upper funnel, reducing the stacking of the turtles and making them more dispersed. At the same time, the water flow lubricates the turtles, reducing the friction between them and the upper screen frame and the middle vibrating screen frame. This reduces the likelihood of the turtles being injured by wear and tear when passing through the screen holes, further lowering the probability of injury during screening. The rate of skin damage caused by friction from the screen holes is reduced from 15% in traditional screening devices to below 4%.
[0014] The distance between the transverse water pipe and the vibrating screening rack is adjusted as the middle baffle moves, adapting to the screening of juvenile turtles of different sizes and ensuring the adaptability of individual juvenile turtles through the gap. The transverse water pipe can be angled to control the spray height and direction of the water nozzles, reducing the chance of juvenile turtles getting stuck near the middle baffle.

[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] This utility model proposes a screening device for juvenile Chinese soft-shelled turtles, comprising: a central vibrating screening frame 1, an upper screen frame 2, and a lower water collection box 3. External elastic buffers 101 are fixedly installed on both sides of the central vibrating screening frame 1. A central permeable hole 102, penetrating both inside and outside, is arranged in an array at intervals in the middle of the central vibrating screening frame 1. A vibrating motor 103 is fixedly installed at the front of the central vibrating screening frame 1. The lower end of the external elastic buffer 101 is fixedly connected to the lower water collection box 3. The central vibrating screening frame 1 and the central permeable hole 102 are both located above the inner side of the lower water collection box 3. The upper screen frame 2 is fixedly connected to the upper part of the central vibrating screening frame 1. Side connecting slides 201 are fixedly installed on both sides of the upper screen frame 2. A first lifting screw 202 is rotatably installed on the inner side of the side connecting slide 201 on one side of the upper screen frame 2. The first lifting screw 202 and the tail end of the middle baffle 203 are threadedly connected. A middle transverse water pipe 204 is rotatably installed on the front side of the middle baffle 203 through a rotating shaft. Water nozzles 205 are arranged in an array at intervals on the front part of the middle transverse water pipe 204. A lower water collection box 3 is installed below the middle vibrating screen frame 1. An upper funnel 301 is fixedly installed on the front side of the lower water collection box 3. An internal pump 302 is installed on the inner side of the lower water collection box 3. The internal pump 302 and the middle transverse water pipe 204 are connected by a flexible hose. The middle transverse water pipe 204 is located on the side of the middle baffle 203 near the upper funnel 301.
[0029] In this embodiment, the two ends of the middle baffle 203 are vertically slidably connected to the side connecting slide 201, respectively. The middle part of the middle baffle 203 is threadedly connected to a second lifting screw 206. The lower end of the second lifting screw 206 is rotatably connected to a lower connecting rod 207 via a rotating shaft. The tail end of the lower connecting rod 207 is rotatably connected to the upper part of the middle transverse water pipe 204 via a rotating shaft. The second lifting screw 206 pushes the middle transverse water pipe 204 to adjust its angle through the lower connecting rod 207. The middle transverse water pipe 204 and the control spray nozzle 205 are tilted and adjusted at the same angle, controlling the spray height and direction of the spray nozzle 205, and controlling the spray nozzle 205 to spray water to disperse the juvenile turtles and reduce the situation where the juvenile turtles get stuck near the middle baffle 203.
[0030] In this embodiment, the upper funnel 301 is located above the front side of the upper screen frame 2, and the water spray nozzle 205 is located on the side of the middle transverse water pipe 204 near the upper funnel 301. The water spray nozzle 205 sprays water onto the juvenile turtles falling from the upper funnel 301, further reducing the stacking of juvenile turtles and making them more dispersed. At the same time, after spraying water, the lubrication effect of the water flow reduces the friction between the juvenile turtles and the upper screen frame 2 and the middle vibrating screening frame 1, reducing the wear and injury of the juvenile turtles as they pass through the screen holes of the upper screen frame 2.
[0031] In Example 2, based on Example 1, the lower part of the middle baffle 203 adopts a bristle structure. The bristles block the juvenile turtles and prevent them from piling up one on top of the other. The flexible and bendable bristles reduce friction damage to the juvenile turtles and reduce the chance of injury.
[0032] The working principle of this embodiment: juvenile turtles enter the upper screen frame 2 through the upper funnel 301. The vibration motor 103 drives the middle vibration screening frame 1 and the upper screen frame 2 to vibrate synchronously. The small juvenile turtles pass through the screen holes of the upper screen frame 2 and fall into the middle vibration screening frame 1, thus achieving the screening of juvenile turtles. The first lifting screw 202 rotates, and the middle baffle 203 moves along the thread axis of the first lifting screw 202 to adjust its height. The distance between the lower end of the middle baffle 203 and the middle vibration screening frame 1 is adjusted. The middle transverse water pipe 204 adjusts its distance from the middle vibration screening frame 1 as the middle baffle 203 moves. The distance between the lower end of the middle baffle 203 and the middle vibrating screening frame 1 is used to allow juvenile turtles to pass through, adapting to the screening of juvenile turtles of different sizes and ensuring the adaptability of the gap for individual juvenile turtles to pass through. The second lifting screw 206 moves axially along the thread, and the second lifting screw 206 pushes the middle transverse water pipe 204 to adjust the angle through the lower connecting rod 207. The middle transverse water pipe 204 and the control spray nozzle 205 tilt and adjust the angle synchronously, controlling the spray height and direction of the spray nozzle 205, and controlling the spray nozzle 205 to spray water to disperse the juvenile turtles and reduce the situation where juvenile turtles get stuck near the middle baffle 203.
[0033] The gap between the middle baffle 203 and the upper screen frame 2 is only wide enough for one juvenile turtle to pass through, reducing the stacking of juvenile turtles. The water spray nozzle 205 sprays water onto the juvenile turtles falling from the upper funnel 301, further reducing the stacking of juvenile turtles and making them more dispersed. At the same time, after spraying water, the lubrication effect of the water flow reduces the friction between the juvenile turtles and the upper screen frame 2 and the middle vibrating screen frame 1, reducing the wear and injury of the juvenile turtles as they pass through the screen holes of the upper screen frame 2, further reducing the probability of injury to the juvenile turtles during screening. The rate of skin damage caused by friction of the screen holes of the juvenile turtles is reduced from 15% in traditional screening devices to below 4%. Water falls through the water permeable hole 102 in the middle vibrating screen frame 1 to the lower water collection box 3 for recycling. The water in the lower water collection box 3 is transported to the middle horizontal water pipe 204 and the water spray nozzle 205 by the internal pump 302, realizing recycling.
