Description

Technical Field

[0001] This invention relates to the field of animal feed testing, and more particularly to a device for spectroscopic detection of nutrient components in animal feed. Background Technology

[0002] Accurately detecting the nutrient content in animal feed is of great significance for scientific feeding and ensuring the nutritional intake of animals; In recent years, spectroscopic detection technology has been widely used in the feed industry due to its advantages such as non-destructive nature, speed, and simultaneous detection of multiple components. However, existing spectroscopic detection devices typically use fixed sample stages when detecting animal feed nutrients, allowing only one sample to be detected at a time, resulting in low detection efficiency. Furthermore, during continuous detection, the spectroscopic detection unit is prone to heat buildup due to prolonged operation, leading to decreased detection performance or even damage, thus shortening the lifespan of the device. Therefore, it is necessary to consider how to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for spectral detection of nutrient components in animal feed. When in use, this device utilizes a rotating disk in conjunction with multiple placement slots to improve overall detection efficiency. Furthermore, during continuous detection, it ensures the heat dissipation performance of the detection section, thereby extending its actual service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for spectral detection of nutrient components in animal feed includes a main body with multiple support bases mounted on its lower end. A support plate is fixedly connected to the left side of the main body, and a horizontal connecting plate is fixedly connected to the left side of the support plate. A detection mechanism includes a detection cylinder fixedly connected to the lower end of the horizontal portion of the L-shaped connecting plate. A second piston plate, which can slide up and down, is disposed inside the detection cylinder. The upper end of the second piston plate is elastically connected to the inner top of the detection cylinder via a spring. A spectral detection head is fixedly connected to the upper end of the second piston plate. A transparent glass plate is inserted through the second piston plate and is fixedly connected to the second piston plate, cooperating with the spectral detection head. A loading and unloading mechanism is used to load and unload the sampled fertilizer.

[0005] Preferably, the loading and unloading mechanism includes a rotating shaft rotatably connected to the upper end of the support plate, and a rotating disk is fixedly connected to the upper end of the rotating shaft.

[0006] Preferably, a mounting bracket is fixedly connected to the lower end of the horizontal connecting plate, a drive motor is mounted on the mounting bracket, the lower end of the rotating shaft passes through the support plate, and pulleys are mounted on both the lower end of the rotating shaft and the output shaft of the drive motor. The two pulleys are connected by a transmission belt.

[0007] Preferably, the upper end of the rotating disk is provided with multiple placement slots, and each placement slot contains a sampling box.

[0008] Preferably, an L-shaped connecting plate is fixedly connected to the left side of the horizontal connecting plate, and a connecting seat is fixedly connected to the left side of the L-shaped connecting plate. A piston cylinder is installed on the connecting seat, and a first piston plate that can slide left and right is provided inside the piston cylinder. A gearbox is installed at the upper end of the horizontal connecting plate. The input shaft of the gearbox is fixedly connected to the output shaft of the drive motor. A drive disc is fixedly connected to the output shaft of the gearbox. A drive rod is rotatably connected to the upper eccentric part of the drive disc. The other end of the drive rod is rotatably connected to the right side of the first piston plate.

[0009] Preferably, a high-pressure heat-conducting cylinder is fixedly connected to the upper end of the L-shaped connecting plate, and multiple heat sinks are installed at equal intervals on the outer side of the high-pressure heat-conducting cylinder. The left side space of the piston cylinder is connected to the outside through a one-way port, and the left side space of the piston cylinder is connected to the high-pressure heat-conducting cylinder through a one-way pipe.

[0010] Preferably, the internal space of the high-pressure temperature-conducting cylinder is connected to the top space of the detection cylinder through a connecting pipe, the top space of the detection cylinder is connected to the outside through a fine hole, a release hole is provided on the side wall of the bottom space of the detection cylinder, and an annular sealing cover is fixedly connected to the lower end of the second piston plate.

[0011] Preferably, both the one-way port and the one-way pipe are equipped with one-way valves. The one-way valve inside the one-way port allows the flow to enter the piston cylinder from the outside in one direction. The one-way valve inside the one-way pipe allows the flow to enter the high-pressure temperature-conducting cylinder from the left side space of the piston cylinder in one direction. The connecting pipe is equipped with a normally open solenoid valve, which opens and closes synchronously with the drive motor.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: 1. During testing, the annular sealing cover moves down to contact the rotating disk, effectively blocking light and reducing interference from external light, creating a stable testing environment for the spectral detection head, ensuring the accuracy of spectral detection of animal feed samples, and improving the reliability of test results.

[0013] 2. The heat sink is used to dissipate heat from the compressed air inside the high-pressure temperature-conducting cylinder, so that the low-temperature gas entering the detection cylinder can dissipate heat from the detection part, reduce the temperature inside the detection cylinder, avoid damage to the detection element caused by high temperature, and effectively extend the service life of the device.

[0014] 3. The rotating disk is driven by a drive motor, which, together with the detection mechanism and the loading and unloading mechanism, enables automatic and continuous detection of multiple samples. Each rotation is at a fixed angle, accurately delivering the sample to the detection position, improving detection efficiency and reducing the intensity of manual operation.

A second piston plate 25 that can slide up and down is provided inside the detection cylinder 20. The upper end of the second piston plate 25 is elastically connected to the inner top of the detection cylinder 20 through a spring 27. A spectral detection head 26 is fixedly connected to the upper end of the second piston plate 25. A transparent glass is provided through the second piston plate 25. The transparent glass is fixedly connected to the second piston plate 25 and cooperates with the spectral detection head 26. A plurality of placement slots 5 are opened at the upper end of the rotating disk 4. A sampling box 6 is placed in each placement slot 5. Furthermore, a processing component (not shown) is also provided at the top of the inner part of the detection cylinder 20 for transmitting the spectral detection head 26 to the device body 1. As one embodiment of the present invention, it also includes a loading and unloading mechanism, which is used to load and unload the sampled fertilizer. The loading and unloading mechanism includes a rotating shaft 30 rotatably connected to the upper end of the support plate 3. A rotating disk 4 is fixedly connected to the upper end of the rotating shaft 30. A mounting frame 9 is fixedly connected to the lower end of the horizontal connecting plate 7. A drive motor 10 is mounted on the mounting frame 9. The lower end of the rotating shaft 30 passes through the support plate 3. Pulleys 11 are mounted on both the lower end of the rotating shaft 30 and the output shaft of the drive motor 10. The two pulleys 11 are connected by a transmission belt 12. In one embodiment of the present invention, an L-shaped connecting plate 8 is fixedly connected to the left side of the horizontal connecting plate 7, and a connecting seat 29 is fixedly connected to the left side of the L-shaped connecting plate 8. A piston cylinder 13 is mounted on the connecting seat 29, and a first piston plate 21 that can slide left and right is provided inside the piston cylinder 13. A gearbox is mounted on the upper end of the horizontal connecting plate 7. The gearbox here is an accelerator. Each time the drive motor 10 is started, the output shaft of the gearbox can rotate multiple times. In this solution, there are three placement slots 5, and the drive motor 10 rotates 120° each time, thus changing the speed. The input shaft of the device is fixedly connected to the output shaft of the drive motor 10. The output shaft of the gearbox is fixedly connected to the drive disc 16. The upper end of the drive disc 16 is eccentrically connected to the drive rod 22. The other end of the drive rod 22 is rotatably connected to the right side of the first piston plate 21. The upper end of the L-shaped connecting plate 8 is fixedly connected to the high-pressure heat-conducting cylinder 17. Multiple heat sinks 18 are installed at equal intervals on the outer side of the high-pressure heat-conducting cylinder 17. The left side space of the piston cylinder 13 is connected to the outside through the one-way port 15. The left side space of the piston cylinder 13 is connected to the high-pressure heat-conducting cylinder 17 through the one-way pipe 14. In one embodiment of the present invention, the internal space of the high-pressure temperature-conducting cylinder 17 is connected to the top space of the detection cylinder 20 through the connecting pipe 19. The top space of the detection cylinder 20 is connected to the outside through the fine hole 23. A release hole 24 is provided on the side wall of the bottom space of the detection cylinder 20. An annular sealing cover 28 is fixedly connected to the lower end of the second piston plate 25. One-way valves are installed inside the one-way port 15 and the one-way pipe 14. The flow direction of the one-way valve inside the one-way port 15 is one-way to the outside and into the piston cylinder 13. The flow direction of the one-way valve inside the one-way pipe 14 is one-way to the left space of the piston cylinder 13 and into the high-pressure temperature-conducting cylinder 17. A normally open solenoid valve is installed inside the connecting pipe 19. The normally open solenoid valve is opened and closed synchronously with the drive motor 10.

[0020] In this invention, when the device for detecting animal feed nutrients by spectroscopy is in its initial state, the second piston plate 25 inside the detection cylinder 20 is in a higher position under the elastic action of the spring 27, the spectral detection head 26 is located in the upper part of the detection cylinder 20, the bottom space of the detection cylinder 20 is connected to the outside through the release hole 24, the annular sealing cover 28 is located above the release hole 24, the top space of the detection cylinder 20 is connected to the outside through the fine hole 23, and the normally open solenoid valve inside the connecting pipe 19 is in the open state. At this time, the animal feed sample to be tested can be placed in the placement slot 5 on the left front. Start the drive motor 10. The output shaft of the drive motor 10 rotates, and through the transmission action of the two pulleys 11 and the transmission belt 12, it drives the rotating shaft 30 to rotate, which in turn drives the rotating disk 4 to rotate. Since there are three placement slots 5 in this scheme, the drive motor 10 rotates by 120° each time, so that the rotating disk 4 rotates by 120° each time, rotating a sampling box 6 containing a sample to directly below the detection cylinder 20. After the drive motor 10 starts, the input shaft of the transmission (accelerator) rotates synchronously with the output shaft of the drive motor 10. Due to the acceleration effect of the transmission, the output shaft of the transmission will rotate multiple times. The output shaft of the transmission drives the drive disc 16 to rotate, and the drive rod 22, which is rotatably connected to the upper eccentric part of the drive disc 16, moves accordingly. Since the other end of the drive rod 22 is rotatably connected to the right side of the first piston plate 21, the first piston plate 21 is driven to slide left and right in the piston cylinder 13. When the first piston plate 21 slides to the left, the left space of the piston cylinder 13 draws in air from the outside through the one-way port 15. When the first piston plate 21 slides to the right, the air in the left space of the piston cylinder 13 is forced into the high-pressure heat-conducting cylinder 17 through the one-way pipe 14. After air enters the high-pressure heat-conducting cylinder 17, multiple heat dissipation fins 18 are evenly spaced on its outer side, which can dissipate heat from the compressed high-temperature air to a certain extent. This results in the air being released at a temperature lower than room temperature, providing better heat dissipation. When the drive motor 10 starts, the normally open solenoid valve closes, preventing air from entering the top space of the detection cylinder 20 through the connecting pipe 19. As air is continuously forced into the high-pressure heat-conducting cylinder 17, the pressure inside gradually increases. When the drive motor 10 stops rotating, the normally open solenoid valve opens, and the high-pressure air in the high-pressure heat-conducting cylinder 17 quickly enters the top space of the detection cylinder 20 through the connecting pipe 19. The space (due to the slow gas release rate of the fine hole 23, the gas pressure accumulates at the top of the detection cylinder 20) pushes the second piston plate 25 to slide downwards, the spring 27 is stretched, the second piston plate 25 drives the spectral detection head 26 to move downwards, and at the same time the transparent glass on the second piston plate 25 moves downwards, so that the spectral detection head 26 can perform spectral detection on the animal feed sample in the sampling box 6 below through the transparent glass. The detection data is displayed on the display screen, and the annular sealing cover 28 moves downwards and contacts the rotating disk 4, which has a good light-blocking effect and ensures the accuracy of detection. In addition, the low temperature gas enters into the detection cylinder 20 and is discharged, which can improve the heat dissipation of the detection part and ensure its service life. After the test is completed, the normally open solenoid valve closes again, blocking the connection between the top space of the detection cylinder 20 and the high-pressure temperature-conducting cylinder 17. At this time, the second piston plate 25 slides upward and resets under the elastic restoring force of the spring 27, driving the spectral detection head 26 back to the upper part of the detection cylinder 20. At the same time, the drive motor 10 starts again, and the rotating disk 4 rotates 120° again, rotating the next sample box 6 containing the sample to the bottom of the detection cylinder 20 (after the last rotation, the next sample box 6 containing the sample can be placed back into the placement slot 5 on the left front). The above detection process is repeated to realize the continuous detection of multiple samples.
