Technical Field
[0001] This utility model relates to the field of environmental monitoring, specifically a multifunctional sampling head suitable for environmental monitoring. Background Technology
[0002] The multi-functional sampling head for environmental monitoring is an innovative device designed specifically for the field of environmental monitoring. It integrates multiple sampling functions and can adapt to the sampling needs of different environmental media, such as air, water, and soil. Soil pollution, in particular, poses a serious threat to the ecological environment and human health. Therefore, regular and accurate testing and monitoring of the soil environment has become an important part of environmental protection and sustainable development. In existing soil environmental monitoring technologies, sampling is the basic step for obtaining soil samples and conducting subsequent analysis. In traditional methods, cleaning the sampling head often requires manual labor, which is not only time-consuming and laborious but also difficult to completely remove residual soil from the surface of the sampling head, increasing the risk of cross-contamination. To address this, we have proposed a multi-functional sampling head suitable for environmental monitoring. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a multifunctional sampling head suitable for environmental monitoring, thus solving the aforementioned problems.

[0008] Preferably, the outer surface cleaning assembly includes a fixed rod, a synchronizing rod, a scraper, and a mud-throwing plate. A fixed rod is fixedly connected to one end of the soil testing frame above and below the window. A scraper is fixedly connected between the ends of the two sets of fixed rods. Two sets of symmetrical synchronizing rods are fixedly connected to the side of the annular plate away from the soil testing frame.

[0010] Preferably, the scraping plate is annular and is slidably fitted onto the outer wall of the soil sampling head.
[0011] Compared with the prior art, this utility model provides a multifunctional sampling head suitable for environmental monitoring, which has the following beneficial effects:
[0012] 1. This multi-functional sampling head, suitable for environmental testing, automatically removes residual soil from the surface of the soil sampled during its retraction process after sampling, avoiding the tediousness of manual cleaning and the risk of cross-contamination. Furthermore, the rotation of the annular plate and mud-throwing plate, driven by a motor, further removes soil from the sides of the scraping plate, ensuring the cleanliness of the sampling head and guaranteeing accurate sampling for the next attempt.
[0013] 2. This multi-functional sampling head, suitable for environmental testing, uses a drive cylinder to propel the soil sampling head for rapid and accurate soil insertion and retraction, greatly improving sampling efficiency. At the same time, the sampling head remains stable during insertion and retraction, reducing sampling errors caused by improper operation and ensuring the accuracy of sampling data.

The head also includes:
[0021] An outer surface cleaning component, which is located at the end of the soil testing frame 1, is used to clean the outer surface of the soil sampling head 5.
[0022] The annular plate 7 is circular in shape, and the driving gear 3 meshes with the annular gear 8.
[0023] A window 6 is provided at one end of the soil testing frame 1, and the soil sampling head 5 extends out of the soil testing frame 1 through the window 6.
[0024] The outer surface cleaning assembly includes a fixed rod 9, a synchronizing rod 10, a scraper 11, and a mud-throwing plate 12. A fixed rod 9 is fixedly connected to one end of the soil testing frame 1 above and below the window 6. A scraper 11 is fixedly connected between the ends of the two sets of fixed rods 9. Two sets of symmetrical synchronizing rods 10 are fixedly connected to the side of the annular plate 7 away from the soil testing frame 1. A mud-throwing plate 12 is fixedly connected to the ends of the two sets of synchronizing rods 10.
[0025] The outer surface cleaning assembly also includes a notch 13, with a notch 13 on one side of each of the two sets of mud-throwing blades 12, and a scraper 11 rotatably installed between the two sets of notches 13.
[0026] The scraping plate 11 is in the shape of a ring and is slidably fitted onto the outer wall of the soil sampling head 5.
[0027] Partial structural description: Annular plate 7: Rotatably installed at the end of the soil testing frame 1, in the shape of a ring, with an annular gear 8 sleeved on the outer wall, the rotation of the annular plate 7 is driven by the rotation of the annular gear 8;
[0028] Ring gear 8: It is sleeved on the outer wall of the ring plate 7 and meshes with the drive gear 3. The rotation of the drive gear 3 drives the rotation of the ring gear 8 and the ring plate 7.
[0029] Fixed rod 9: Fixed rod 9 is fixedly connected to one end of the soil testing frame 1 above and below the window 6, for supporting and fixing other components;
[0030] Synchronization rod 10: Two sets of symmetrical synchronization rods 10 are fixed to the side of the annular plate 7 away from the soil testing frame 1, and rotate synchronously with the rotation of the annular plate 7.
[0031] Scraping plate 11: It is ring-shaped and slides onto the outer wall of the soil sampling head 5, with both ends fixed to the ends of the two sets of fixing rods 9 respectively. During the retraction of the soil sampling head 5, the scraping plate 11 scrapes away the residual soil on the outer surface of the soil sampling head 5;
[0032] Mud-slinging plates 12: The ends of the two sets of mud-slinging plates 12 are fixedly connected to the ends of the two sets of synchronizing rods 10, and rotate synchronously with the rotation of the synchronizing rods 10. During rotation, the mud-slinging plates 12 scrape off the mud on the sides of the scraping plates 11, ensuring the cleanliness of the scraping plates 11;
[0033] Notch 13: Opened on one side of the two sets of mud-throwing plates 12, used to install and fix the scraper plate 11, so that the scraper plate 11 can rotate between the notches 13, thereby realizing its scraping function.
[0034] Working principle: When soil testing is required, the drive cylinder 4 is started first. The piston rod on the drive cylinder 4 pushes the soil sampling head 5 outward. The soil sampling head 5 slides outward in the window 6 and gradually inserts into the soil. After the test is completed, the soil sampling head 5 is retracted. During the retraction process, the soil sampling head 5 slides in the scraping plate 11. The scraping plate 11 scrapes away the residual soil on the outer surface of the soil sampling head 5. The soil is scraped to one side of the scraping plate 11. After the soil sampling head 5 retracts into the soil testing frame 1, the drive motor 2 is started. The output shaft on the drive motor 2 drives the drive gear 3 to rotate. The ring gear 8 meshes with the drive gear 3 to drive the ring plate 7 to rotate at the end of the soil testing frame 1. The two sets of synchronous rods 10 rotate synchronously with the rotation of the ring plate 7, driving the two sets of mud-throwing plates 12 to rotate synchronously. During the rotation, the two sets of mud-throwing plates 12 scrape away the soil on the side of the scraping plate 11.
