[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-5 , an embodiment provided by the utility model:

[0029] A mixing device for uniform stirring includes a fixed base 1, a base 14 is fixedly provided on one side of the fixed base 1, a mixing box 8 is fixedly provided on the upper end surface of the base 14, a sliding groove 9 is opened at the midpoint of one side of the outer wall of the fixed base 1, a screw 11 is rotatably provided inside the sliding groove 9, a linkage block 3 is threadedly sleeved on the outer wall of the screw 11, a cover plate 6 is fixedly provided on the end of the linkage block 3 away from the screw 11, a feed port 4 is opened on one side of the upper end surface of the cover plate 6, and a crushing mechanism 10 is installed inside the feed port 4, and a stirring mechanism 7 is installed at the midpoint of the lower end surface of the cover plate 6;

[0030] The crushing mechanism 10 includes two crushing rollers 1001, and the two crushing rollers 1001 are rotatably arranged inside the feed port 4 through a rotating shaft 1002. One end of the two rotating shafts 1002 is fixedly provided with a gear 1003 and the two gears 1003 are meshed. The stirring mechanism 7 includes a stirring shaft 701, and the outer wall of the stirring shaft 701 is fixedly provided with multiple fixed blocks 704. Both sides of the outer walls of the multiple fixed blocks 704 are fixedly provided with stirring rods 702. The ends of the multiple stirring rods 702 away from the fixed blocks 704 are connected to the protrusions 706 through springs 707, and the other ends of the protrusions 706 are connected to the scrapers 703 through mounting blocks 705.

[0031] Specifically, since the screw 11 is threadedly connected to the linkage block 3, and the linkage block 3 is vertically slidably set in the sliding groove 9, it cannot rotate. That is, when the screw 11 rotates, it will drive the linkage block 3 with the outer threaded connection to perform lifting and lowering movements, thereby realizing the lifting and lowering movement of the cover plate 6.

[0032] Reference Figure 1 and Figure 3 , a No. 1 motor 2 is fixedly arranged on the upper end surface of the fixing seat 1, and one end of the screw 11 is fixedly arranged at the output end of the No. 1 motor 2;

[0033] Specifically, when the No. 1 motor 2 is started, the No. 1 motor 2 drives the screw 11 at the output end to rotate. At this time, the linkage block 3 with the outer thread sleeve passively completes the lifting movement, thereby completing the lifting and opening and closing functions of the cover plate 6.

[0034] Reference Figure 1 and Figure 2, the middle point of the upper end surface of the cover plate 6 is fixedly provided with the second motor 5, and one end of the stirring shaft 701 is fixedly provided with the output end of the second motor 5;

[0035] Specifically, when the No. 2 motor 5 is started, the stirring shaft 701 at the output end is driven to rotate, and then the fixed block 704 drives the stirring rod 702 to move. Since one end of the stirring rod 702 is connected to the scraper 703 by means of a spring 707, a protrusion 706 and a mounting block 705, and the outer wall of the scraper 703 is in contact with the inner wall of the mixing box 8, the stirring and mixing of the internal raw materials is achieved while completing the scraping of the inner wall.

[0036] Reference Figure 1 and Figure 5 , a groove 13 is formed at one end of the stirring rod 702 away from the fixed block 704, a spring 707 is embedded in the groove 13, one side of the mounting block 705 is fixedly connected to the protrusion 706 and the other side is fixedly connected to the inner wall of the scraper 703; the outer wall of the scraper 703 is an inclined section at the lower end, and the outer wall of the scraper 703 is an arc surface;

[0037] Specifically, when the cover plate 6 moves downward, the stirring mechanism 7 at the lower end is driven to move downward synchronously, and the inclined cross-section of the outer wall of the scraper 703 can play an auxiliary guiding function when entering the mixing box 8, so that it can enter the inner wall of the mixing box 8 more smoothly. When the scraper 703 enters the mixing box 8, it is forced to move inward so that the mounting block 705 and the protrusion 706 on the inside generate an extrusion force on the spring 707. The spring 707 contracts and drives the protrusion 706 to move, prompting the protrusion 706 to embed into the groove 13. Due to the recovery and rebound of the spring 707, the scraper 703 can better fit the inner wall of the mixing box 8.

[0038] Reference Figure 2 and Figure 4 A third motor 1004 is installed on one side of the inner portion of the cover plate 6, and one end of one of the two rotating shafts 1002 is fixedly arranged at the output end of the third motor 1004;

[0039] Specifically, the third motor 1004 drives the rotating shaft 1002 at the output end to rotate. Since the two rotating shafts 1002 are meshed and connected by the gear 1003, when one of the rotating shafts 1002 rotates, the other rotating shaft 1002 rotates relatively. The two rotating shafts 1002 are connected to two crushing rollers 1001, thereby realizing the rotational movement of the two crushing rollers 1001.

[0040] Reference Figure 1 and Figure 3 A discharge pipe 12 is fixedly provided on one side of the outer wall of the mixing box 8 near the lower end; the discharge pipe 12 provided at the lower end can facilitate the discharge of the mixed raw materials.

[0041] Working principle: When using the device, the cover plate 6 can be opened first, and the stirring mechanism 7 at the lower end of the cover plate 6 is separated from the mixing box 8. At this time, the stirring mechanism 7 can be cleaned separately and the inner wall of the mixing box 8 can be cleaned;

[0042] Secondly, the cover plate 6 can be directly opened to inject raw materials inward, and then the cover plate 6 can be covered and the stirring mechanism 7 can be used for mixing and stirring. When particles or solid industrial raw materials need to be added for mixing and stirring after the cover plate 6 is covered, they can be injected inward from the feed port 4 at the upper end. The crushing mechanism 10 inside the feed port 4 crushes and breaks up the particles or solid raw materials, so that they can be better mixed and stirred after falling into the mixing box 8, and the mixing is more uniform.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
