The surface of the rotating shaft 501 is fixedly connected to a pulley 507. The surface of the pulley 507 is transmission-connected to a conveyor belt 508. When in use, start motor 1 506 to rotate a set of rotating shafts 501 connected thereto, and under the action of the pulley 507 and the conveyor belt 508, the other set of rotating shafts 501 rotates, so that when the raw materials are poured into the feed hopper 3, the two sets of crushing rollers 502 will first crush the raw materials to facilitate subsequent mixing. The screen 504 is provided to facilitate screening as needed.

[0025] Specifically, two motors 509 are fixedly mounted on the surface of the mixing barrel 1. Two sets of motors 509 are symmetrically arranged. Stirring rods 510 are fixedly connected to the output ends of the motors 509. Stirring rods 510 extend through and are rotatably connected to the surface of the mixing barrel 1. Raw materials pass through the screen 504 and enter the mixing barrel 1 through the feed hopper 3. When the motors 509 are activated, the two sets of stirring rods 510 rotate to mix the raw materials.

[0026] Specifically, the end of the rotating shaft 501 away from the motor 506 is fixedly connected to a cylinder 511. The surface of the cylinder 511 is rotatably connected to a connecting rod 512. The other end of the connecting rod 512 is rotatably connected to a collision block 513. The surface of the feed hopper 3 is provided with a chute 514 and is connected to the placement slot 503. The collision block 513 is slidably connected to the surface of the chute 514.

A plurality of cutting blades 67 are fixedly connected to the surface of the connecting shaft 62 and cooperate with the stirring rod 510. Since the feed hopper 3 and the discharge hopper 4 are located on different sides, the feed port 66 and the discharge port 64 need to be located on the same side to achieve different alignment and staggering conditions during feeding, mixing, and discharging. During mixing, the fixed cutting blades 67 on the rotating shaft 501 cooperate with the rotating stirring rod 510 to achieve more efficient mixing.

[0030] The utility model sets a mixing mechanism 5, starts the motor 1 506 to rotate a set of rotating shafts 501 connected thereto, and under the action of the pulley 507 and the conveyor belt 508, another set of rotating shafts 501 rotates, so that when the raw materials are poured into the feed hopper 3, the two sets of crushing rollers 502 will first crush the raw materials to facilitate subsequent mixing. The crushed raw materials fall on the screen 504, and when the rotating shaft 501 rotates, it drives the cylinder 511 to rotate, so that the connecting rod 512 drives the collision block 513 to continuously move up and down along the chute 514, and continuously hits the screen 504 to facilitate For the screening of raw materials, the raw materials pass through the screen 504 and enter the mixing barrel 1 from the feed hopper 3. The motor 2 509 is started to rotate the two sets of stirring rods 510 to mix the raw materials. There are multiple sets of screens 504 of different specifications placed on the placement rack 515 of the support frame 505. You can choose the appropriate screen 504 according to actual needs and slide it into the placement slot 503. By setting the mixing mechanism 5, the raw materials are crushed by the crushing roller 502 as needed before mixing and the screen 504 of appropriate specifications is used for screening. The crushed raw materials are more conducive to subsequent stirring and mixing. The usability of the equipment is effectively improved. In addition, by setting up a protective mechanism 6, when feeding, starting the motor three 61 makes the connecting shaft 62 rotate, and then the upper turntable 65 and the lower turntable 63 rotate synchronously, and the feed port 66 is aligned with the feed hopper 3. At this time, the discharge port 64 and the discharge hopper 4 are staggered, which is convenient for feeding. When mixing, starting the motor three 61 makes the connecting shaft 62 rotate ninety degrees. At this time, the feed port 66 and the feed hopper 3 and the discharge port 64 and the discharge hopper 4 are staggered, so that foreign matter such as dust will not spread from the feed hopper 3 to the outside of the mixing barrel 1 during mixing. When discharging, When mixing, start motor three 61 to make the connecting shaft 62 rotate another ninety degrees. At this time, the discharge port 64 is aligned with the discharge hopper 4, and the feed hopper 3 is staggered with the feed port 66, which is convenient for discharging.
