[0016] In the above scheme, thanks to the setting of the sampling mechanism, when the belt scale body is running, there is no need to stop sampling the material, which is convenient for sampling and analysis of the material. During the sampling process, the sealing effect of the material is good, and dust is not easy to be emitted. Through the setting of the sealing mechanism, the sampling hole can be quickly moved to close after the sampling is completed, further reducing the degree of dust emission. It is highly practical.

After the material is taken out, the sealing plate can be closed. The principle is simple and easy to implement, which effectively prevents the flying and leakage of materials during the metering process, reduces environmental pollution, and can be widely promoted.

The support frames 10 are fixedly connected to the inner wall of the driving plate 5 and are rotatably connected to the driving gear 11.

[0035] Reference Figure 4 , Figure 5 The sampling mechanism 3 includes a sampling box 18, a rotating shaft 19, a mounting rod 17, a lifting plate 16 and a support plate 21. The support plate 21 is vertically distributed with the lifting plate 16. The mounting rod 17 is vertically arranged at the bottom of the lifting plate 16. The end of the mounting rod 17 away from the lifting plate 16 is rotatably connected to the rotating shaft 19. The sampling box 18 is a hollow semi-cylindrical structure and is fixedly connected to the rotating shaft 19. A connecting block 25 is protruded from the end of the lifting plate 16. A lifting groove is vertically opened on the surface of the support plate 21. The connecting block 25 slides vertically along the lifting groove.

[0036] The working principle of the technical solution provided by the present invention is as follows. When in use, the material to be weighed is first poured from the feed bin 2 into the interior of the belt scale body 1. As the belt scale body 1 is moved, the material moves out from the discharge port, and the material passing through the interior of the belt scale body 1 will be measured and weighed. When it is necessary to sample the material, the telescopic cylinder 6 extends out to drive the driving plate 5 to rise, and then the driving plate 5 drives the sealing plates 7 on both sides to rise. After the sealing plates 7 leave the sampling hole 8, the electric telescopic rod 15 contracts accordingly, and the moving plate 14 fixedly connected to the electric telescopic rod 15 slides against the inner wall of the driving plate 5. The moving plate 14 drives the driving gear 11, and the driving gear 11 rotates, thereby driving the screw 13 to rotate, and the driving rod 9 threadedly connected to the screw 13 is forced toward the slide The inside of the hole 29 shrinks and slides, and then the sealing plate 7 moves away from the top of the sampling hole 8. At this time, the first motor 22 starts, driving the screw 20 to rotate, and the connecting block 25 is forced to drive the lifting plate 16 to descend. The sampling box 18 at the bottom of the lifting plate 16 passes through the sampling hole 8 and enters the inside of the belt scale body 1. Then the second motor 24 starts, and the driving wheel 23 rotates to drive the driven wheel 27 to rotate through the transmission belt 26, and then the rotating shaft 19 rotates. The sampling box 18 digs the moving material inside the belt scale body 1. When the sampling box 18 rotates ninety degrees, it stops rotating. At this time, the lifting plate 16 is raised. After the lifting plate 16 leaves the sampling hole 8, the sealing plate 7 can be adjusted back to its original position, and the sampling hole 8 continues to be closed. At this time, the operator can take away the material inside the sampling box 18.
