Description

Technical Field

[0001] This utility model relates to the field of nutrient component detection technology for aquaculture feed, and in particular to an instrument for detecting and analyzing the nutrient components of aquaculture feed. Background Technology

[0002] Aquaculture feed is a food product specifically designed to provide nutrients for aquatic animals. Its purpose is to meet the nutritional needs of aquatic animals at different growth stages and physiological states, including energy, protein, fat, carbohydrates, vitamins, and minerals. However, the nutritional needs of different species and growth stages of aquatic animals vary greatly. Therefore, it is necessary to test the nutritional components of aquaculture feed. There are many methods for testing the nutritional components of aquaculture feed, but the most convenient one is to use a near-infrared light detector.

[0003] When detecting the nutritional components of aquaculture feed using a near-infrared light detector, the particle size and stacking thickness of the feed both affect the detection results. Stacking causes the spectral baseline of the feed sample to drift, resulting in changes in position or intensity. This makes the quantitative analysis of fat content based on spectral characteristics inaccurate. Furthermore, in a stacked state, due to the complex changes in optical path and scattering, absorption peaks may overlap, interfering with the accurate analysis of the content of each component. Inconsistent particle size makes it difficult to ensure that each small sample uniformly contains various particle components during the reduction process, thus affecting the accuracy of the final test sample. Based on the above problems, this application proposes an aquaculture feed nutrient component detection and analysis instrument. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an aquaculture feed nutrient composition analyzer to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nutritional component analyzer for aquaculture feed includes a mounting base, a vibration assembly on the top of the mounting base, a discharge plate on the top of the mounting base via the vibration assembly, fixed plates on both the front and rear sides of the discharge plate, a screen fixed between the facing surfaces of the fixed plates, the screen being positioned above the fixed plates on the same vertical projection plane, a mounting frame fixed on the top of the mounting base, a conveying assembly for facilitating the transport of aquaculture feed inside the mounting frame, and a detection assembly for facilitating the detection of nutritional components in the aquaculture feed on the top of the mounting frame.

[0007] Preferably, a baffle plate is fixedly disposed between the opposing surfaces of the fixed plates, and a discharge pipe is fixedly disposed on the right side of the baffle plate, the inlet of the discharge pipe being funnel-shaped.

[0008] Preferably, the vibration assembly includes a mounting frame fixedly installed on the top of the mounting base, a compression spring fixedly installed on the top of the mounting frame, a connecting frame fixedly installed on the top of the compression spring, a discharge plate fixedly installed on the top of the connecting frame, and a vibration motor fixedly installed on the upper side wall of the connecting frame.

[0009] Preferably, the conveying assembly includes a servo motor fixedly installed on the front side of the mounting frame, an active roller fixedly provided at the output end of the servo motor, a conveyor belt meshing on the surface of the active roller, a driven roller meshing inside the conveyor belt, and the driven roller rotatably disposed inside the mounting frame.

[0010] Preferably, the detection component includes a mounting vertical plate fixedly installed on the top of the mounting frame, a fixing column fixedly installed on the rear side of the mounting vertical plate, a fixing ring fixedly installed on the surface of the fixing column, a rectangular plate fixedly installed at the bottom of the fixing ring, and a near-infrared light detector body fixedly installed at the bottom of the rectangular plate.

[0011] Preferably, both the discharge plate and the screen are inclined, and both are made of stainless steel.

[0012] Preferably, the number of compression springs is several, and the several compression springs are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This aquaculture feed nutrient composition analyzer uses a vibration component to drive the discharge plate to vibrate, and the discharge plate drives the screen to vibrate through a fixed plate, so that the screen screen can screen the aquaculture feed, ensuring that the particle size of the aquaculture feed particles is consistent. At the same time, the discharge plate vibrates and discharges the screened aquaculture feed, so that the aquaculture feed falls evenly onto the conveying component, and the aquaculture feed is tested by the detection component. This avoids the stacking of feed samples, which would cause the spectral baseline to drift and affect the accuracy of the test sample. It also avoids the possibility of absorption peaks overlapping and interfering with the accurate analysis of the content of each component, and avoids the impact of particle size on the accuracy of the final test sample.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-5A nutrient composition analyzer for aquaculture feed includes a mounting base 1. A vibration assembly is mounted on the top of the mounting base 1, and a discharge plate 6 is mounted on the top of the mounting base 1 via the vibration assembly. Fixing plates 7 are fixedly mounted on both the front and rear sides of the discharge plate 6. A screen 8 is fixedly mounted between the facing surfaces of the fixing plates 7. Both the discharge plate 6 and the screen 8 are inclined. Both the discharge plate 6 and the screen 8 are made of stainless steel. The inclined arrangement of the discharge plate 6 and the screen 8 facilitates the movement of aquaculture feed, and the stainless steel material of the discharge plate 6 and the screen 8 makes them durable and resistant to damage. Wear and tear make the discharge plate 6 and screen 8 more durable. On the same vertical projection plane, screen 8 is located above the fixed plate 7. The vibration assembly includes a mounting bracket 2 fixedly installed on the top of the mounting base 1. A compression spring 3 is fixedly installed on the top of the mounting bracket 2, and a connecting bracket 4 is fixedly installed on the top of the compression spring 3. There are several compression springs 3, and they are symmetrically distributed, making the connecting bracket 4 more stable and preventing it from tilting. The discharge plate 6 is fixedly installed on the top of the connecting bracket 4, and a vibration motor is fixedly installed on the upper side wall of the connecting bracket 4. Machine 5, the vibrating motor 5 drives the connecting frame 4 to vibrate through the compression spring 3, causing the discharge plate 6 to vibrate through the fixed plate 7 and the screen 8, thereby screening the aquaculture feed and facilitating the vibration feeding of the aquaculture feed. This results in more uniform feeding of the aquaculture feed and avoids the aquaculture feed from piling up and affecting the test results. The top of the mounting base 1 is fixedly equipped with a mounting frame 11, and the mounting frame 11 is equipped with a conveying component to facilitate the transportation of aquaculture feed. The top of the mounting frame 11 is equipped with a mechanism to facilitate the transportation of aquaculture feed. The detection component for testing the nutritional components of aquaculture feed has a baffle plate 9 fixedly installed between the opposing surfaces of the fixed plate 7. A discharge pipe 10 is fixedly installed on the right side of the baffle plate 9. The inlet of the discharge pipe 10 is funnel-shaped. The baffle plate 9 can block aquaculture feed that has not passed through the screen 8, while the discharge pipe 10 facilitates the discharge of aquaculture feed that has not passed through the screen 8. The funnel-shaped inlet also facilitates the entry of aquaculture feed into the discharge pipe 10, thereby avoiding the accumulation of too much aquaculture feed on the screen 8, which would prevent the aquaculture feed from being screened.

[0022] Specifically, the conveying assembly includes a servo motor 12 fixedly installed on the front side of the mounting frame 11. An active roller 13 is fixedly installed at the output end of the servo motor 12. A conveyor belt 14 is meshed on the surface of the active roller 13. A driven roller 15 is meshed inside the conveyor belt 14. The driven roller 15 is rotatably installed inside the mounting frame 11. The active roller 13 is driven to rotate by the servo motor 12. The active roller 13 and the driven roller 15 cooperate to make the conveyor belt 14 convey the aquaculture feed. The servo motor 12 can accurately control the rotation speed of the active roller 13, thereby facilitating the control of the conveying speed of the conveyor belt 14 on the aquaculture feed. This avoids the aquaculture feed being conveyed too quickly, resulting in too short a time for near-infrared light to irradiate each feed particle, causing some weak absorption peaks of some components to go undetected. This makes the detection of the nutritional components of the aquaculture feed more complete.

[0023] Specifically, the detection assembly includes a mounting vertical plate 16 fixedly installed on the top of the mounting frame 11, a fixing post 17 fixedly installed on the rear side of the mounting vertical plate 16, a fixing ring 18 fixedly installed on the surface of the fixing post 17, a rectangular plate 19 fixedly installed at the bottom of the fixing ring 18, and a near-infrared light detector body 20 fixedly installed at the bottom of the rectangular plate 19. The near-infrared light detector body 20 is installed at the bottom of the rectangular plate 19 by bolts.

[0024] It is worth mentioning that the aforementioned near-infrared light detector body 20 mainly consists of a sampling system, an optical system, a protection and adaptation system, a real-time data processing module, a communication interface, and a dust removal module. The near-infrared light detector body 20 operates based on the principle that after a sample is irradiated with near-infrared light, the organic molecular groups in the sample absorb near-infrared light of a specific wavelength, generating an absorption spectrum related to the sample composition. Through a pre-established mathematical model, the spectrum is analyzed and processed to quickly obtain the sample's composition information. Therefore, the aforementioned near-infrared light detector body 20 can be considered prior art and will not be described in detail further.

[0025] This aquaculture feed nutrient composition analyzer is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: The aquaculture feed to be tested is conveyed to the top of the screen 8 via a conveying device. The vibration motor 5 is started, which drives the connecting frame 4 to vibrate via the compression spring 3. The connecting frame 4 then drives the discharge plate 6 to vibrate. The discharge plate 6, through the fixed plate 7, drives the screen 8 to vibrate, causing the aquaculture feed to move to the right along the surface of the screen 8. The aquaculture feed is screened through the screen 8 and falls to the top of the discharge plate 6. The vibrating discharge plate 6 drives the aquaculture feed to vibrate, causing it to move to the right and fall evenly onto the conveyor belt 14. The servo motor 12 drives the output end to rotate the active roller 13. The active roller 13 drives the driven roller 15 to rotate through the conveyor belt 14, causing the conveyor belt 14 to move the aquaculture feed to the right. When the aquaculture feed moves to below the near-infrared light detector body 20, the near-infrared light detector body 20 detects the nutritional components of the aquaculture feed.
