In view of this, in order to solve this technical problem, a scraper and a spring are added to the application document.

[0031] According to the above content, in order to improve the service life of the gear metering pump.

[0032] In the present embodiment: it includes a metering pump body 1, a protective shell 2 is fixedly connected to the front side of the metering pump body 1, a push rod 15 inside the sleeve 14, and a pin 16 at the top of the push rod 15 pushes the clamping plate 17 and the second spring 18 at the bottom to slide toward the bottom end. At this time, the slide bar 21 slides toward the bottom end inside the first fixed block 19 and the second fixed block 20. At this time, the rotating plate 8 is not clamped by the second fixed block 20, and the first spring 7 drives the rotating plate 8 to slide along the inside of the square groove of the slide bar 21. The rotating plate 8 slides into the inside of the slide groove and pushes the clamping plate 17 upward. The clamping plate 17 pushes the oil collecting groove 22 to slide inside the metering pump body 1 and scrapes the inner wall of the metering pump body 1.

[0033] A square groove is provided at the bottom end of the slide rod 21 , and a rotating plate 8 is rotatably connected inside the square groove of the bottom end of the slide rod 21 . Without the second fixed block 20 pressing against the rotating plate 8 , the first spring 7 drives the rotating plate 8 to slide along the inside of the square groove of the slide rod 21 .

[0034] In this embodiment: a driven gear 9 is fixedly connected to the outer side of the rotating shaft 10, and the rotating gear 11 rotates to drive the driven gear 9 at the bottom to rotate. During the rotation, impurities in the water are filtered by the filter disc 12 on the rear side of the rotating gear 11 and adsorbed by the magnetic block 13.
