[0031] Specifically, when liquid needs to be measured, electromagnetic valve one 1101 is opened, electromagnetic valve two 1201 is closed, liquid enters the inside of metering pipe body 100 along liquid inlet pipe 110, photoelectric liquid level sensor 400 detects the height or volume of liquid in real time, when the liquid to be measured reaches the height of photoelectric liquid level sensor 400, electromagnetic valve one 1101 is closed, electromagnetic valve two 1201 is opened, and the liquid to be measured in the inside of metering pipe body 100 is discharged from liquid outlet pipe 120, when part of substance in liquid is attached to the inner wall of metering pipe body 100, rotate metering pipe body 100, so that scraping assembly 340 in the inside of metering pipe body 100 is scraped to the inner wall, and then blowing pipe 330 blows air to the inside of metering pipe body 100, and the residual material is blown out.

[0032] Embodiment one

[0033] As shown in the drawing, Figures 2-4 The scraping assembly 340 includes a fixed ring 341, which is sleeved and fixed on the outer wall of the blowing pipe 330 at the bottom end. The outer wall of the fixed ring 341 is fixedly connected with four support rods 342 at equal angles. The other ends of the four support rods 342 are fixedly connected with support rods 342.

[0034] In the embodiment, the four scrapers 343 are arranged at equal angles, and the outer wall of the scraper 343 is attached to the inner wall of the metering pipe body 100. The cross section of the scraper 343 is arc-shaped, which is matched with the shape of the bottom of the metering pipe body 100. When the metering pipe body 100 rotates, the residual liquid or substance on the inner wall of the metering pipe body 100 is scraped off by the four scrapers 343. While the metering pipe body 100 rotates, the two electric telescopic rods 310 are controlled to drive the connecting plate 320 to descend, that is, the air blowing pipe 330 drives the scraper assembly 340 to move downward, so that the scraper 343 can fully scrape the inner wall of the metering pipe body 100. Since the cross section of the scraper 343 is arc-shaped, the scraped liquid or substance is collected at the bottom end of the scraper 343. At this time, air is blown out from the bottom end of the air blowing pipe 330, so that the liquid collected at the bottom end of the scraper 343 is blown out.

The gear 231 and the gear ring 130 are in meshing transmission, so that the metering pipe body 100 rotates. The electric telescopic rod 310 is controlled to contract or elongate, so that the inner wall of the metering pipe body 100 is automatically cleaned.

[0037] As shown in Figures 1-2 In the embodiment, the top surface of the stand column 200 is fixedly connected with an air blowing pump 500.
