Description

Technical Field

[0001] This invention relates to the field of feed testing device technology, specifically a testing device and method for shrimp-specific functional feed for disease prevention and control. Background Technology

[0002] In shrimp farming, feed quality directly affects shrimp growth and disease resistance. As specialized feeds with specific preventative effects, the nutritional composition and safety indicators of shrimp-specific disease control feeds are crucial. Currently, feed testing processes typically separate feed grinding from subsequent nutritional and safety indicator testing, requiring various equipment, resulting in cumbersome operations and low efficiency. Furthermore, existing grinding equipment suffers from inconsistent grinding performance; uneven feed powder particle size affects subsequent extraction, leading to inaccurate test results. The transfer of ground feed to testing equipment also poses a risk of spillage and contamination, wasting samples and potentially compromising the cleanliness of the testing environment. Additionally, existing testing devices have low automation levels, resulting in insufficient mixing of the extract and feed powder during extraction, further reducing accuracy and failing to meet the demands for efficient and precise testing of shrimp-specific disease control feeds.

[0003] Existing technologies do not involve an integrated crushing-extraction-detection structure, lack a device that can integrate feed crushing, extract mixing and index detection, and also lack control components that can accurately control the operation of each stage. Specifically, they lack a top cover structure that can seal and snap together with the crushing cylinder, a docking port structure that can stably connect the crushing cylinder and the detection chamber, and a servo drive structure that can drive the stirring shaft to achieve uniform mixing.

Detailed Implementation

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The extraction detection assembly includes an extraction liquid filling hopper 400 mounted on a top cover 360 and a stirring shaft 421 rotatably mounted in the middle of the top cover 360. Stirring blades 422 are fixedly mounted on the outer wall of the stirring shaft 421. A nutritional function detection unit 430 and a safety indicator detection unit 440 are fixedly mounted on the top of the top cover 360. The detection probes of the nutritional function detection unit 430 and the safety indicator detection unit 440 both extend through the top cover 360 into the extraction tank 320.

[0021] The specific application scenario of this embodiment is as follows: The nutritional function detection unit 430 adopts an FDR-300 feed nutrient composition analyzer, and the safety index detection unit 440 adopts an HPLC-20A high-performance liquid chromatography analyzer. During operation, the shrimp control functional feed to be tested enters the grinding cylinder 100. The feed is ground by the grinding blades 231 on the inner wall of the grinding cylinder 100. After being screened by the screen 120 on the bottom inner wall of the grinding cylinder 100, the ground feed powder falls into the extraction pool 320 inside the detection chamber 300, which is inserted and connected to the grinding cylinder 100. Subsequently, the top cover 360 is inserted and installed. At the top of the extraction tank 320, an appropriate amount of extractant is added into the extraction tank 320 through the extractant filling hopper 400. The stirring shaft 421 installed in the middle of the top cover 360 is rotated to drive the stirring blades 422 on its outer wall to rotate, so that the feed powder and the extractant are fully mixed and extracted. The nutritional function detection unit 430 and the safety index detection unit 440 installed on the top of the top cover 360 are activated. The detection probes of the two units pass through the top cover 360 and extend into the extractant in the extraction tank 320 to detect the nutritional function index and safety index of the feed, respectively. After the detection is completed, the waste liquid is discharged through the liquid outlet pipe 330 on the side wall of the extraction tank 320.

[0022] Example 2: Figures 1-5 The crushing assembly includes a top cover 200 that is snapped onto the top of the crushing cylinder 100. A sealing ring is provided at the connection between the top cover 200 and the crushing cylinder 100. The outer walls of the top of the crushing cylinder 100 are rotatably connected by buckles 240. A C-shaped bracket 241 is fixedly installed on the outer wall of the top of the top of the top cover 200. The buckles 240 and the C-shaped bracket 241 are engaged and connected. A feed filling hopper 210 is fixedly installed on the outer wall of the top of the top of the top cover 200. The bottom outer wall of the feed filling hopper 210 is fixedly connected to the inner wall of the top cover 200 through a feed pipe 211. A first valve 213 is fixedly installed on the outer wall of the feed pipe 211. A first end cap 212 is provided on the top of the feed filling hopper 210. A first servo motor 220 is fixedly installed on the outer wall of the top of the top of the top of the top cover 200.

[0023] The specific application scenario of this embodiment is as follows: The first servo motor 220 adopts an SGMAH-08AAA41 servo motor. During operation, the upper cover 200 is first snapped onto the top of the crushing cylinder 100. The sealing ring at the connection between the upper cover 200 and the crushing cylinder 100 ensures the sealing performance. The buckles 240 on the outer wall of the top of the crushing cylinder 100 are rotated so that the buckles 240 and the C-shaped brackets 241 on the outer wall of the top of the upper cover 200 are engaged to achieve a stable fixation between the upper cover 200 and the crushing cylinder 100. The first end cover 212 on the top of the feed filling hopper 210 is opened, and the feed to be tested is added into the feed filling hopper 210. The first valve 213 on the outer wall of the feed pipe 211 is opened, and the feed enters the crushing cylinder 100 through the feed pipe 211. The first servo motor 220 is started to provide power output for subsequent feed crushing operations. The first servo motor 220 can precisely control the speed to ensure a stable and efficient crushing process. Closing the first valve 213 and the first end cover 212 can prevent feed powder from splashing during the crushing process.

[0024] Example 3: Figures 4-6 The output shaft of the first servo motor 220 is connected to the drive shaft 230 via a coupling. The crushing blade 231 is detachably and fixedly installed on the outer wall of the drive shaft 230. The screen 120 has a limiting hole 121 in the middle. The bottom end of the drive shaft 230 is rotatably connected to the inner wall of the limiting hole 121. The bottom of the crushing cylinder 100 has a first docking port 110. The top of the detection chamber 300 has a second docking port 310. The first docking port 110 and the second docking port 310 are rotatably connected. The bottom outer wall of the detection chamber 300 is uniformly and fixedly installed with anti-slip support corners 350. The outer wall of the liquid outlet pipe 330 is fixedly installed with a third valve 340. The bottom of the extract filling hopper 400 is connected to the inner wall of the top cover 360 via the filling pipe 410.

[0025] The specific application scenario of this embodiment is as follows: During operation, the output shaft of the first servo motor 220 drives the drive shaft 230 to rotate via a coupling. The crushing blades 231, which are fixedly installed on the outer wall of the drive shaft 230, rotate synchronously with the drive shaft 230 to crush the feed entering the crushing cylinder 100. The limiting hole 121 in the middle of the screen 120 is engaged and rotated with the bottom end of the drive shaft 230, which can provide limiting support for the drive shaft 230, prevent the drive shaft 230 from shifting during rotation, and ensure the crushing accuracy of the crushing blades 231. After crushing, the feed is discharged through the bottom of the crushing cylinder 100. The first docking port 110 is connected to the second docking port 310 on the top of the detection chamber 300 to achieve precise docking between the crushing cylinder 100 and the detection chamber 300, so that the crushed feed powder falls smoothly into the extraction tank 320 inside the detection chamber 300. The anti-slip support corner 350 on the bottom outer wall of the detection chamber 300 can ensure the stability of the detection chamber 300 and prevent slippage during the detection process. The third valve 340 on the outer wall of the liquid outlet pipe 330 can control the timing of waste liquid discharge. The extract liquid filling hopper 400 delivers extract liquid into the top cover 360 through the bottom filling pipe 410 to prepare for subsequent extraction operations.

[0026] Example 4: Figures 6-8 A second valve 411 is fixedly installed on the outer wall of the filling pipe 410. A second end cap 412 is provided on the top of the extraction liquid filling hopper 400. A second servo motor 420 is fixedly installed on the top outer wall of the top cover 360. The output shaft of the second servo motor 420 is fixedly connected to the stirring shaft 421 through a coupling. The stirring blade 422 is detachably and fixedly installed on the outer wall of the stirring shaft 421 for uniformly mixing the feed powder and the extraction liquid.

[0027] The specific application scenario of this embodiment is as follows: The second servo motor 420 adopts an SGMAH-04AAA41 servo motor. During operation, the second end cap 412 on the top of the extraction liquid filling hopper 400 is opened, and the extraction liquid is added into the extraction liquid filling hopper 400. The second valve 411 on the outer wall of the filling pipe 410 is opened, and the extraction liquid enters the top cover 360 through the filling pipe 410 and then flows into the extraction tank 320. The second servo motor 420 is started, and the output shaft of the second servo motor 420 drives the stirring shaft 421 to rotate through the coupling. The stirring blade 422, which is fixedly installed on the outer wall of the stirring shaft 421, rotates synchronously with the stirring shaft 421 to stir and mix the feed powder and the extraction liquid in the extraction tank 320. Since the stirring blade 422 is detachably fixed, different specifications of stirring blade 422 can be replaced according to the extraction requirements. The second servo motor 420 can precisely adjust the stirring speed to ensure that the feed powder and the extraction liquid are fully contacted and mixed, improve the extraction effect, and provide a guarantee for subsequent accurate detection. Closing the second valve 411 can prevent the extraction liquid from flowing back during the extraction process.

[0028] Example 5: Figure 1and Figure 2 It also includes a control component, including a controller 500, which is fixedly installed on the top outer wall of the top cover 360. The controller 500 is electrically connected to the first servo motor 220, the second servo motor 420, the nutrition function detection unit 430 and the safety indicator detection unit 440. The controller 500 is electrically connected to an external power supply for powering the device.

[0029] The specific application scenario of this embodiment is as follows: The controller 500 adopts a PLC-S7-200 programmable logic controller. During operation, the controller 500 establishes electrical connections with the first servo motor 220, the second servo motor 420, the nutritional function detection unit 430, and the safety indicator detection unit 440 through wires, respectively, to achieve centralized control of the operating status of each component. The operator can preset the speed and running time of the first servo motor 220 and the second servo motor 420 through the controller 500 to control the parameters of the crushing and mixing operation. At the same time, the controller 500 can receive the detection data transmitted by the nutritional function detection unit 430 and the safety indicator detection unit 440, and perform preliminary processing and display on the data. The controller 500 is electrically connected to an external power supply, which supplies power to the controller 500 itself and the various electronic components connected to it, ensuring the stable operation of each link of the device.
