The first end of the outlet pipe 1 is placed inside the storage hopper body 3 and below the chute 4 installed on the storage hopper body 3. An inlet 5 is provided on the top surface of the first end of the outlet pipe 1, which allows the interior of the outlet pipe 1 to communicate with the interior of the storage hopper body 3. The second end of the outlet pipe 1 is placed outside the storage hopper body 3, and an outlet 6 is provided on the bottom surface of the second end of the outlet pipe 1. The receiving box 2 is placed below the outlet 6. The material entering the outlet pipe 1 at the inlet 5 can reach the outlet 6 along the outlet pipe 1, and the material at the outlet 6 can fall into the receiving box 2.

[0026] The sampling device provided in this embodiment is particularly suitable for sampling powdered sodium fluorosilicate. The first end of the outlet pipe 1 is positioned below a chute 4 installed on the storage hopper body 3, allowing material flowing down the chute 4 into the storage hopper body 3 to enter the outlet pipe 1 through an inlet 5 on the top surface of the first end. The material entering the outlet pipe 1 at inlet 5 travels along the outlet pipe 1 to an outlet 6 on the bottom surface of the second end, and finally falls into a receiving box 2, achieving automated sampling. When the sampling device provided in this embodiment is installed on the storage hopper body 3 for pre-packaging of products, it directly interacts with product production. The line connection enables continuous sampling, reducing manual operation and human intervention, improving sample representativeness, and enabling automatic sampling from the start of production until the end of the specified production batch. This achieves full-process sampling with good sample representativeness and simplifies product sampling, eliminating the need for manual bag-lifting and sampling, greatly improving sampling efficiency. The device has a simple structure and is easy to operate. During sampling, the sampling personnel only need to go to the site, take out the sample from the receiving box 2, mix it simply, and bottle it. This not only reduces labor intensity and frees up personnel from sampling, but also improves the working environment, ensuring safety and environmental protection, and embodies the people-oriented philosophy.

[0027] As a preferred embodiment of this invention, the lead-out pipe 1 is fixedly installed on the storage container body 3 by a fixing flange, which facilitates disassembly and assembly; the receiving box 2 needs to be locked to prevent sample contamination, loss or replacement, and to ensure sample safety.

[0028] Furthermore, the inside of the outlet pipe 1 is equipped with a forced drive device, which can push the material at the inlet 5 to the outlet 6, effectively improving the sampling efficiency.

[0029] As a preferred embodiment of this invention, the forced drive device includes a conveying shaft 7, on which a spiral pushing blade 8 is spirally wound and fixed. Both the conveying shaft 7 and the spiral pushing blade 8 are placed inside the outlet pipe 1. The conveying shaft 7 can rotate, and the spiral pushing blade 8 rotates with the conveying shaft 7. The rotation of the spiral pushing blade 8 can push the material at the inlet 5 to the outlet 6. The conveying shaft 7 and the spiral pushing blade 8 are preferably made of SS304 stainless steel to prevent corrosion from materials such as sodium fluorosilicate.

[0030] As a preferred embodiment of this invention, a drive motor 9 is provided on the second end of the lead-out pipe 1. The drive motor 9 is connected to the conveying shaft 7 for transmission. The drive motor 9 can provide power for the rotation of the conveying shaft 7. The drive motor 9 is preferably a cycloidal pinwheel type geared motor with a power of 0.25KW, a working voltage of 380V, a protection level of IP54, an insulation level of F, good wear resistance, and a long service life.

[0031] As a preferred embodiment of this invention, the drive motor 9 is controlled to work at regular intervals by a program pre-set in the control box to achieve automatic interval sampling. In practical applications, the program is set according to the sampling amount and the sampling time.

[0032] Furthermore, the receiving box 2 is equipped with a separator 10, which can receive the material falling into the receiving box 2. When the material falls onto the separator 10, it is automatically separated into two identical samples under the action of gravity. After sampling, one sample is directly kept as a retention sample, and the other sample is sent to the laboratory for analysis and testing. The sampling personnel can directly take the samples when they arrive at the site and bottle them separately, which reduces a lot of manual operation.

[0033] Furthermore, inside the receiving box 2, a guide tube 11 is provided above the divider 10. The guide tube 11 can guide the material falling into the receiving box 2 into the divider 10, which facilitates precise feeding into the divider 10.

[0034] Furthermore, the bottom of the guide tube 11 is provided with a movable cover 12, which can seal or open the bottom of the guide tube 11 to facilitate the control of feeding into the separator 10.

[0035] Furthermore, the sampling device provided in this embodiment also includes a discharge tube 13. The top end of the discharge tube 13 is fixedly connected to and communicates with the discharge port 6, and the bottom end of the discharge tube 13 extends into the guide tube 11, which can effectively avoid external pollution. The discharge process is safe and environmentally friendly. The discharge tube 13 is preferably a φ64mm plastic flexible tube, which is easy to manufacture and use.

[0036] As a preferred embodiment of this invention, the feed inlet 5 has a length of 100mm and a width of 10mm, which can effectively prevent clogging.

The storage hopper body 3 can store materials, and the chute 4 is fixedly disposed above the storage hopper body 3. The chute 4 can guide the materials to slide down into the storage hopper body 3.

[0039] The storage hopper provided in this embodiment is particularly suitable for sampling powdered sodium fluorosilicate. The first end of the outlet pipe 1 is positioned below the chute 4 installed on the main body 3 of the storage hopper. This allows material flowing down the chute 4 into the main body 3 to enter the outlet pipe 1 through the inlet 5 on the top surface of the first end. The material entering the outlet pipe 1 through inlet 5 travels along the outlet pipe 1 to the outlet 6 on the bottom surface of the second end, and finally falls into the receiving box 2, achieving automated sampling. The sampling device from Embodiment 1 is installed on the main body 3 of the storage hopper before product packaging, directly connected to the product production line. The device enables continuous sampling, reducing manual operation and human intervention, improving sample representativeness, and allowing for automatic sampling from the start of production until the end of the specified production batch. This achieves full-process sampling with good sample representativeness and simplifies product sampling, eliminating the need for manual bagging and sampling, thus greatly improving sampling efficiency. The device has a simple structure and is easy to operate. During sampling, personnel only need to go to the site, take the sample from the receiving box 2, mix it simply, and bottle it. This not only reduces labor intensity and frees up personnel from sampling but also improves the working environment, ensuring safety and environmental protection, and embodies the people-oriented philosophy.
