[0028] Reference Figure 1 and Figure 2 and Figure 3As shown, the utility model provides a technical scheme: flotation reagent quantitative adding device includes charge barrel 1, the right end fixedly connected with conveying cylinder 4 and support rod 9 of charge barrel 1, the inner wall of conveying cylinder 4 is provided with auger 11, the circular arc surface fixedly connected with the blanking tube 6 of conveying cylinder 4, the right end of conveying cylinder 4 is installed with first motor 5, and the output end of first motor 5 is fixed with auger 11, the other end fixedly connected with weighing box 8 of support rod 9, the front surface of weighing box 8 is inserted with weighing plate 7, the upper end of weighing plate 7 is installed with electronic scale 12, the right end of weighing box 8 is installed with pneumatic cylinder 10, and pneumatic cylinder 10 is fixed with weighing plate 7, the upper end of weighing box 8 is provided with scraping assembly 2, and the right end of weighing box 8 is provided with auxiliary assembly 3.

[0029] The specific settings and functions of the scraping assembly 2 and the auxiliary assembly 3 will be described below.

[0030] Referring to Figure 4 As shown in the embodiment, the scraping assembly 2 includes a scraping frame 21 slidingly connected to the inner wall of the weighing box 8, L-shaped frames 22 fixedly connected to the upper ends of both sides of the scraping frame 21, a knocking mechanism 23 provided at the upper end of the scraping frame 21. By setting the scraping assembly 2, when it is necessary to scrape the flotation reagent adhering to the inner wall of the weighing box 8, the scraping frame 21 is made to slide on the inner wall of the weighing box 8 by the driving mechanism, so that the flotation reagent adhering to the inner wall of the weighing box 8 is scraped. Then, by the knocking mechanism 23, the scraping frame 21 that has scraped the flotation reagent is knocked, so that the flotation reagent possibly adhering to the scraping frame 21 is knocked off, thereby achieving the effect of scraping the flotation reagent adhering to the inner wall of the weighing box 8 as much as possible and avoiding affecting the matching effect. The knocking mechanism 23 includes a square iron block 234 provided at the upper end of the scraping frame 21, which slides on the L-shaped frame 22. The worker releases the limiting mechanism, so that the square iron block 234 freely falls and hits the scraping frame 21, thereby knocking the scraping frame 21 that has scraped the flotation reagent. L-shaped frames 22 are fixedly connected to the upper ends of both sides of the weighing box 8. A mounting shaft 231 is rotatably connected to the circular arc surface of the mounting shaft 231. A baffle 232 is rotatably connected to the mounting shaft 231. Rotating the baffle 232 on the mounting shaft 231 releases the limiting of the square iron block 234. A torsional spring 233 is fixedly connected to the upper end of the baffle 232. The other end of the torsional spring 233 is fixed to the mounting shaft 231. By setting the torsional spring 233, the baffle 232 is reset. A scraping surface 28 is formed at the lower end of the scraping frame 21. By setting the scraping surface 28, the flotation reagent scraped by the scraping frame 21 falls from the scraping frame 21. A mounting ring 24 is fixedly connected to the circular arc surface of the blanking tube 6. A lead screw 26 is rotatably connected to the upper end of the mounting ring 24. A sliding rod 25 is fixedly connected to the upper end of the mounting ring 24. The lead screw 26 is threadedly connected to the left L-shaped frame 22. The right L-shaped frame 22 slides on the sliding rod 25. The rotation of the lead screw 26 on the mounting ring 24 moves the scraping frame 21 connected to the L-shaped frame 22 under the limiting of the sliding rod 25. A second motor 27 is installed at the lower end of the mounting ring 24. The output end of the second motor 27 is fixed to the lead screw 26. Starting the second motor 27 makes the lead screw 26 rotate.

[0031] Referring to Figure 2 In the embodiment, the auxiliary assembly 3 includes a rubber pad 31 fixedly connected to the inner wall of the weighing box 8, which is in contact with the weighing plate 7. By setting the rubber pad 31 in close contact with the weighing plate 7, the floating agent is prevented from being taken out when the weighing plate 7 is pulled out.

[0032] Working principle:

[0033] When using the adding device, the floating agent is poured into the charging barrel 1, and then the first motor 5 on the conveying cylinder 4 is started to rotate the auger 11, so that the floating agent is transferred and discharged from the discharge pipe 6 to the electronic scale 12 on the weighing plate 7 in the weighing box 8 on the supporting rod 9. When the specified weight is reached, the cylinder 10 on the mounting bracket is started to pull out the weighing plate 7, so that the agent falls into the container in the mineral flotation process, thereby completing the quantitative addition of the floating agent. When it is necessary to scrape off the floating agent attached to the inner wall of the weighing box 8, the second motor 27 is started to rotate the lead screw 26, and the lead screw 26 on the mounting ring 24 is rotated. Under the limiting of the sliding rod 25, the scraping frame 21 connected by the L-shaped bracket 22 moves, so that the scraping frame 21 slides on the inner wall of the weighing box 8, and the floating agent attached to the inner wall of the weighing box 8 is scraped off. Then, the baffle 232 on the mounting shaft 231 is rotated to release the limiting of the square iron block 234, so that the square iron block 234 freely falls and hits the scraping frame 21, thereby knocking the scraping frame 21 that has scraped off the floating agent. The scraping frame 21 that has scraped off the floating agent is knocked, so that the floating agent that may be attached to the scraping frame 21 is knocked off, thereby achieving the scraping of the floating agent attached to the inner wall of the weighing box 8 as much as possible, avoiding the effect of affecting the matching effect. By setting the torsional spring 233, the baffle 232 is reset. By setting the scraping surface 28, the floating agent scraped off by the scraping frame 21 falls from the scraping frame 21. By setting the rubber pad 31 in close contact with the weighing plate 7, the floating agent is prevented from being taken out when the weighing plate 7 is pulled out.
