Processing box 1 inside is provided with drive assembly.
[0032] Drive assembly structure: drive assembly includes motor 12, and motor 12 is fixedly connected in processing box 1 front end. Motor 12 output fixedly connected with first bevel gear 13, and first bevel gear 13 outer ring is connected with second bevel gear 14 meshing. Second bevel gear 14 inside fixedly connected with rotating column 15, and rotating column 15 top fixedly connected with rotating disc 16. Rotating column 15 outer ring rotationally connected with connecting frame 17, and the both sides inside of connecting frame 17 are slidably connected with sliding rod 20. Sliding rod 20 both ends are fixedly connected with swing lever 21, and rotating disc 16 top fixedly connected with limit post 19. Sliding rod 20 between fixedly connected with arc 18, and arc 18 and limit post 19 are mutually matched. Swing lever 21 rear end top rotationally connected with connecting column 22, and connecting column 22 top rotationally connected with material box 11. Material box 11 one end bottom rotationally connected with electric push rod 24, and electric push rod 24 bottom is rotationally connected with swing lever 21. Material box 11 top fixedly connected with the baffle 23 that distributes evenly.
[0033] Before detection preparation: before carrying out nitrogenous fertilizer parameter detection, the nitrogenous fertilizer sample to be detected is placed in material box 11. At this time, the baffle 23 on the top of material box 11 plays a role, on the one hand prevents sample overflow in subsequent operation process, on the other hand promotes sample distribution to be more evenly in material box 11, provides basic conditions for accurate detection.
[0034] Position adjustment of sample box: after the preparation work is completed, the electric push rod 24 is started. The electric push rod 24 performs telescopic movement, and the telescopic movement drives the swing rod 21 connected thereto to rotate around the connecting column 22. The rotation of the swing rod 21 further adjusts the inclination angle of the sample box 11, so that the sample in the sample box 11 is in a preliminarily suitable detection position. Then, the motor 12 is started, and the output end of the motor 12 drives the first bevel gear 13 to rotate. Since the first bevel gear 13 and the second bevel gear 14 are in meshing relationship with each other, the rotation of the first bevel gear 13 drives the second bevel gear 14 to rotate. When the second bevel gear 14 rotates, the rotating column 15 fixedly connected thereto rotates, and the rotating column 15 drives the rotating disc 16 at the top to rotate. The limiting column 19 at the top of the rotating disc 16 rotates together with the rotating disc 16, and the limiting column 19 slides in the arc-shaped ring 18, and the sliding of the limiting column 19 drives the arc-shaped ring 18 and the sliding rod 20 connected thereto to slide left and right. The swing rods 21 at both ends of the sliding rod 20 swing with the movement of the sliding rod 20, and the swing rods 21 drive the sample box 11 to swing through the connecting column 22. Through the cooperation of the electric push rod 24 and the motor 12 and the like, the sample in the sample box 11 can be more fully exposed to the detection environment, and a suitable detection state is reached.
[0035] Position adjustment of spectrometer: after the sample box 11 and the sample inside it are adjusted to a suitable position, the first electric slide rail 2 is started. The first electric slide rail 2 starts to work, drives the first sliding block 3, the supporting column 4, the cross plate 5 and the like to move along the left and right directions of the processing box 1. In this process, the spectrometer 10 gradually approaches the sample box 11 in the horizontal direction. Then the second electric slide rail 6 is started, and the second electric slide rail 6 drives the second sliding block 7, the moving plate 8 and the like to move, so that the spectrometer 10 is further adjusted in the direction perpendicular to the movement direction of the first electric slide rail 2, thereby accurately aiming at the sample in the sample box 11. Then the air cylinder 9 is started, and the air cylinder 9 is elongated to push the spectrometer 10 to approach the sample, so that the spectrometer 10 and the sample reach a suitable detection distance.
[0036] Spectrum detection and parameter acquisition: after the spectrometer 10 is adjusted to a suitable position and approaches the sample, a specific spectrum is emitted to irradiate the nitrogen fertilizer sample. The spectrometer 10 receives the spectrum signals reflected or transmitted by the sample, and finally obtains the related parameters of the nitrogen fertilizer through professional analysis of the spectrum signals, thereby completing the detection of the parameters of the nitrogen fertilizer.
[0037] Working principle: the nitrogen fertilizer sample to be detected is placed in the material box 11, the baffle 23 on the top of the material box 11 can prevent the sample from overflowing during the detection process and make the sample more uniformly distributed. Start the electric push rod 24, the electric push rod 24 is telescopic to drive the swing rod 21 to rotate around the connecting column 22, thereby adjusting the inclination angle of the material box 11, so that the sample is in a suitable detection position, start the motor 12, the motor 12 drives the first bevel gear 13 to rotate, the first bevel gear 13 meshes with the second bevel gear 14, thereby driving the second bevel gear 14 to rotate, the second bevel gear 14 drives the rotating column 15 to rotate, the rotating column 15 drives the rotating disc 16 to rotate. The limiting column 19 on the top of the rotating disc 16 rotates with the rotating disc 16, the limiting column 19 slides in the arc-shaped ring 18, driving the arc-shaped ring 18 and the sliding rod 20 connected therewith to slide left and right. The swing rod 21 at both ends of the sliding rod 20 swings with the movement of the sliding rod 20, the swing rod 21 drives the material box 11 to swing through the connecting column 22, so that the sample in the material box 11 can be more fully exposed to the detection environment. After the material box 11 and the sample in it are adjusted to the appropriate position, start the first electric sliding rail 2, the first electric sliding rail 2 drives the first sliding block 3, the supporting column 4, the cross plate 5 and other components to move along the processing box 1 in the left and right directions, so that the spectrometer 10 approaches the material box 11 in the horizontal direction. Then start the second electric sliding rail 6, the second electric sliding rail 6 drives the second sliding block 7, the moving plate 8 and other components, so that the spectrometer 10 further adjusts the position perpendicular to the movement direction of the first electric sliding rail 2, and accurately aligns the sample in the material box 11.
