Description

TECHNICAL FIELD

[0001] The utility model relates to near infrared spectrum analysis equipment field especially relates to a kind of near infrared spectrum analysis detection sample cell rotating mechanism. BACKGROUND

[0002] In near infrared spectrum analysis technology, the conventional method is usually placed in the sample pool with bottom transparent sample (such as grain, etc.) for detection, and then the sample is analyzed by fixed detection window. However, this method has certain deficiencies, such as limited detection area, resulting in less detection sample, thereby affecting the accuracy and reliability of detection results, in addition, the fixed position between sample pool and detection window also limits the improvement of detection efficiency. SUMMARY

[0003] The embodiment of the present application provides a kind of near infrared spectrum analysis detection sample pool rotating mechanism, solve the technical problem that when the sample is analyzed by fixed detection window in prior art scheme, there is limited detection area, less detection sample, thereby affecting the accuracy and reliability of detection results, while the fixed position between sample pool and detection window also limits the improvement of detection efficiency.

[0004] The technical scheme adopted by the embodiment of the present application is as follows:

[0005] A kind of near infrared spectrum analysis detection sample pool rotating mechanism, including detection base, sample pool for placing sample, driving device for driving the rotation of the sample pool, rotating disc being arranged at the top of the detection base, fixed seat being installed at the bottom of the detection base and for limiting the rotation of the positioning block of sample pool;Two groups of the positioning block being symmetrically placed are installed on the top of the detection base;Two groups of the positioning block are attached to the sample pool;The driving device is installed on the fixed seat, and the output shaft of the driving device is connected to the rotating disc through the detection base transmission;Silicone rubber pad is arranged between the sample pool and the rotating disc;Detection window is opened at the position close to the rotating disc of the detection base.

[0006] Further technical solutions are as follows: the driving device is a motor.

[0007] One or more technical solutions provided in the embodiment of the present application have at least the following technical effects or advantages:

[0008] 1. Due to the use of a detection base, sample cell, drive unit, rotating disk, fixed base, positioning blocks, silicone rubber pad, and detection window, when a sample needs to be detected, it is first placed in the sample cell with a transparent bottom. Since the sample cell is placed on the rotating disk, and a silicone rubber pad is installed between the sample cell and the rotating disk, the silicone rubber pad increases the friction between the sample cell and the bottom of the sample cell. Therefore, when the output shaft of the drive unit drives the rotating disk to rotate, it also drives the sample cell to rotate together. At this time, the detection window can detect a ring-shaped detection area formed by the rotation of the sample cell, thereby increasing the sample volume that can be detected. When the sample cell is rotating, the two sets of positioning blocks can effectively position the sample cell, so that the rotating disk is exactly in the center of the sample cell, thus greatly improving the accuracy and reliability of the detection results.

[0012] This application provides a near-infrared spectroscopy analysis sample cell rotation mechanism, which solves the technical problem that existing solutions, when performing spectral analysis on samples through a fixed detection window, have limited detection area and small sample volume, thus affecting the accuracy and reliability of the detection results. At the same time, the fixed position between the sample cell and the detection window also limits the improvement of detection efficiency.

[0013] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0014] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0015] A near-infrared spectroscopy analysis sample cell rotation mechanism, such as Figure 1 and Figure 2As shown, including detection base 1, for placing the sample sample pool 2, for driving sample pool 2 rotation drive device 3, provided in the detection base 1 top rotary disc 4, installed in the detection base 1 bottom fixed seat 5 and for limiting the rotation of the sample pool 2 positioning block 6. Detection base 1 top is equipped with two sets of symmetrically placed positioning block 6. Two sets of positioning block 6 are attached to the sample pool 2. Drive device 3 is installed on the fixed seat 5, and the drive device 3 output shaft passes through the detection base 1 transmission connection to the rotary disc 4. The sample pool 2 and the rotary disc 4 are provided with a silicone rubber pad 7. Detection base 1 is provided with a detection window 11 near the rotary disc 4.

[0016] The bottom of the sample pool 2 is made of quartz glass. The rotary disc 4 is rotatably connected in the groove provided in the top of the detection base 1. The top of the detection base 1 is fixedly provided with two sets of symmetrically placed positioning blocks 6. The drive device 3 is preferably a motor. The drive device 3 is fixedly installed on the fixed seat 5, and the output shaft of the drive device 3 is transmission connected to the rotary disc 4 through the detection base 1. The silicone rubber pad 7 is installed between the sample pool 2 and the rotary disc 4, which can increase the friction between the bottom of the sample pool 2.

[0017] Because of the adoption of the detection base 1, the sample pool 2, the drive device 3, the rotary disc 4, the fixed seat 5, the positioning block 6, the silicone rubber pad 7 and the detection window 11, when the sample needs to be detected, first place the sample in the bottom transparent sample pool 2, because the sample pool 2 is placed on the rotary disc 4, and the silicone rubber pad 7 is installed between the sample pool 2 and the rotary disc 4, which can increase the friction between the bottom of the sample pool 2, so when the output shaft of the drive device 3 drives the rotary disc 4 to rotate, it will also drive the sample pool 2 to rotate, at this time the detection window 11 can detect a circular detection area formed when the sample pool 2 rotates, thereby increasing the amount of sample detection. When the sample pool 2 is in a rotating state, the two sets of positioning blocks 6 can effectively position the sample pool 2, so that the rotary disc 4 is located at the center of the sample pool 2, thereby greatly improving the accuracy and reliability of the detection result.
