DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] like Figure 1 As shown, an automatic quantitative feeding tank includes a tank body 1, a motor 2 is installed on the top of the tank body 1, a rotating shaft 3 is connected to the output end of the motor 2, the rotating shaft 3 extends into the tank body 1, and a stirring blade 4 is installed on the rotating shaft 3. The stirring blade 4 is used to stir the liquid in the tank body 1. On the one hand, it reduces the air in the liquid, and on the other hand, it effectively prevents the liquid from sticking to the inner wall of the tank body 1 when it is stationary. A scraper mechanism 5 is symmetrically installed on the periphery of the rotating shaft 3. The scraper mechanism 5 is used to clean the inner wall of the tank body 1. A feed port 6 and a discharge port 7 are respectively provided on the top and bottom of the tank body 1, and valves are installed on the feed port 6 and the discharge port 7.

[0021] like Figure 2-3 As shown, the scraper mechanism 5 includes a scraper 52, and the scraper 52 also includes a plate body 521 and a scraper 522. The scraper 522 is installed on one side of the plate body 521, and a connecting rod 51 is evenly arranged on the other side of the plate body 521. The connecting rod 51 is fixed to the periphery of the rotating shaft 3. The scraper 522 fits the inner wall of the tank body 1. When the rotating shaft 3 rotates, the scraper 522 rotates along the inner wall of the tank body 1 and scrapes off the sticky liquid on the inner wall of the tank body 1, so as to ensure the accuracy of the feeding amount when quantitative feeding;

[0022] Furthermore, the cross section of the scraper 522 is in an inclined state, so that the scraper 522 can more easily scrape off the sticky liquid on the inner wall of the tank body 1;

[0023] A slide groove 523 is longitudinally provided on the surface of the plate body 521, and a cleaning member 53 is slidably installed in the slide groove 523. The cleaning member 53 includes a floating plate 531, and the floating plate 531 is slidably connected in the slide groove 523. A cleaning knife 532 is provided on one side of the floating plate 531. The cleaning knife 532 is in contact with the surface of the scraper 522, and the cleaning knife 532 is used to scrape the liquid on the surface of the scraper 522; wherein the floating plate 531 can float by the liquid, so that the floating plate 531 can slide up and down by the position of the liquid, thereby scraping the liquid on the surface of the scraper 522;

[0024] Furthermore, the side of the floating plate 531 away from the plate body 521 is in an inclined state, so that when the plate body 521 rotates along the inner wall of the tank body 1, the resistance encountered by the floating plate 531 is reduced, thereby reducing the influence of the resistance on the up and down movement of the floating plate 531;

[0025] The surface of the plate body 521 is evenly provided with mounting holes 524 in the longitudinal direction, and the pressure sensor 533 can be installed in the mounting hole 524. The pressure sensor 533 is connected to the external controller. The position of the quantitative liquid is determined before refilling, and then the pressure sensor 533 is installed in the mounting hole 524 at the corresponding position. When the liquid enters the tank body 1, the floating plate 531 gradually moves up until it contacts the pressure sensor 533. The pressure sensor 533 transmits a signal to the external controller, and the external controller closes the valve at the feed port 6, thereby achieving the purpose of automatic quantitative measurement of the liquid.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
