This requires a long time of stirring to achieve the desired mixing effect, and the mixing efficiency is low. After mixing, the inner wall of the mixer will have residual or adhered colored sand due to the admixture, which will affect the subsequent mixing, resulting in uneven proportions of the subsequent mixing and affecting the mixing results. Therefore, we propose a colored sand mixer to solve the above problems. Utility Model Content

[0022] The transmission gear 6 forms a rotating structure with the rack 3 on the mixing barrel 1 through the cover plate 5 and the transmission shaft 4, so that the transmission gear 6 can move in the rack 3 through the rotation of the transmission shaft 4, thereby rotating on its own, and the transmission gear 6 and the cover plate 5 are movably connected with the first transmission rod 7 through the rotating shaft, so that the transmission gear 6 can rotate on its own while moving with the cover plate 5 when the cover plate 5 rotates.
[0023] The scraper 9 is obliquely arranged on the surface of the first rotating rod 8, so as to guide the scraped colored sand into the lower discharge port through the arc structure, and the outer side of the scraper 9 is an arc structure, so that the first rotating rod 8 can better contact with the mixing barrel 1 when rotating with the first transmission rod 7, thereby scraping off the colored sand adhering to the inner wall of the mixing barrel 1.
[0024] The first transmission rod 7, the second transmission rod 11 and the third transmission rod 12 are respectively driven by bevel gears, so that the first rotating rod 8 and the rotating roller 13 are driven to rotate by the rotation of the first transmission rod 7 and the third transmission rod 12 respectively.
[0025] The rotating roller 13 is arranged between the cover plate 5 and the support rod 15 through the rotating shaft, so that the colored sand in the mixing barrel 1 can be turned over and stirred by cooperating with the first spiral blade 14 through the driving of the third transmission rod 12, and arc-shaped guide plates are arranged on both sides of the rotating roller 13 to facilitate guiding the colored sand so that it enters the first spiral blade 14 on the rotating roller 13, and can also stir the colored sand along with the cover plate 5.

[0027] Working principle: When using the colored sand mixer, first, pour the colored sand and the mixture to be mixed into the mixing barrel 1 in proportion through the feed port, and then start the motor 2, so that the motor 2 drives the transmission shaft 4 to rotate, thereby driving the cover plate 5, the support rod 15, and the second spiral blade 16 on the transmission shaft 4 to rotate, and the rotation of the second spiral blade 16 will continuously flip the colored sand at the bottom upward, and then the flipped colored sand will be driven by the rotating roller 13, the support rod 15 and the guide plate on the support rod 15 to rotate and stir;
[0028] At the same time, the rotation of the cover plate 5 will drive the transmission gear 6 to move in the rack 3 at the top of the mixing barrel 1, so that the transmission gear 6 drives the first transmission rod 7 at the bottom to start rotating, and the rotation of the first transmission rod 7 will drive the second transmission rod 11 and the third transmission rod 12 connected to it through the bevel gear to rotate, so that the rotating roller 13 connected to the third transmission rod 12 drives the first spiral blade 14 to rotate in the mixing barrel 1 following the rotation of the third transmission rod 12, so that the colored sand driven by the rotating roller 13, the support rod 15 and the guide plate on the support rod 15 is turned over and mixed for the second time;
[0029] At the same time, the cleaning structure composed of the first rotating rod 8, the scraper 9 and the brush 10 between the cover plate 5 and the end of the support rod 15 also rotates with the rotation of the second transmission rod 11, so that the scraper 9 and the brush 10 clean the inner wall of the mixing barrel 1, and the scraped colored sand will move to the bottom or the inner side along the inclined surface of the scraper 9, thereby avoiding the problem of colored sand sticking due to the mixture. After the stirring is completed, the electric telescopic door 17 is opened to make the colored sand fall directly from the conical discharge port, so that it can be used directly later.
