[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 4, an automatic cyclic sand mill, wherein a cylinder 2 is welded to the inner wall of a mounting frame 1, so that a first driving motor 4 can be welded to the side of the mounting frame 1, and thus the output shaft of the first driving motor 4 can drive a first rotating rod 5 to rotate. The rotating first rotating rod 5 can drive a filter barrel 3 to rotate on the inner wall of the cylinder 2. A feed slot 11 is formed at the top of the cylinder 2, and the feed slot 11 penetrates through the inner wall of a rotating cylinder 7. When the rotating cylinder 7 is installed, the inner wall of the cylinder 2 can be welded to the side of the rotating cylinder 7. Since a rotating member 6 is welded to the side of the rotating cylinder 7 close to the filter barrel 3, the outer wall of the rotating member 6 is rotatably connected to a groove formed in the side of the filter barrel 3. One end of the first rotating rod 5 away from the first driving motor 4 is welded to the side of the filter barrel 3, and the first rotating rod 5 can drive the filter barrel 3 to rotate. At the same time, a second driving motor 8 is welded to the side of the mounting frame 1 away from the first driving motor 4, so that the output shaft of the second driving motor 8 can drive a second rotating rod 9 to rotate. The rotating second rotating rod 9 can drive a stirring rod 10 to rotate on the inner wall of the filter barrel 3. Thus, when the stirring rod 10 rotates, it can agitate the material, and when the stirring rod 10 rotates, it can also crush large materials, which is convenient for the material to be sieved, so that the agitated material can be sieved through the filter barrel 3. At the same time, since the driving directions of the first driving motor 4 and the second driving motor 8 are opposite, when the material rotates in the filter barrel 3, small materials can be sieved first, so that the material can be sieved better. When a feed plate 12 is welded inside the feed slot 11, the middle of the feed plate 12 is fixedly penetrated and installed inside the feed slot 11 formed in the cylinder 2; at the same time, the inner end is fixed and communicated with the rotating cylinder 7. When materials need to be added, the materials can be sent into the inside of the filter barrel 3 through the feed plate 12. When a slide plate 13 is installed on the inner wall of the rotating cylinder 7, the added materials can slide into the inside of the filter barrel 3 through the outer wall of the rotating cylinder 7, thus facilitating the agitation of the materials.

[0022] Please refer to Figures 1 - 2 , three discharge slots 14 are formed in the outer wall of the cylinder 2. The inner walls of the three discharge slots 14 are fixedly connected with discharge plates 15. The bottom of the discharge plate 15 is fixedly connected with a connecting cylinder 16. The bottom of the connecting cylinder 16 is fixedly connected with a material receiving plate 17. A material receiving frame 18 is inserted into the inner wall of the material receiving plate 17. A handle is provided on the side of the material receiving frame 18. By forming the discharge slots 14 in the outer wall of the cylinder 2, discharging is facilitated. At the same time, the discharge plates 15 installed on the inner walls of the discharge slots 14 can discharge the materials into the inside of the connecting cylinder 16, and then the materials are collected into the inside of the material receiving frame 18 through the material receiving plate 17. In this utility model, due to the handle installed on the side of the material receiving frame 18, it is convenient to take out the collected materials.

[0023] Please refer to Figure 4, on the surface of the mounting frame 1 close to the first driving motor 4, two third driving motors 19 are fixedly connected. The output shafts of the two third driving motors 19 are both fixedly connected with third rotating rods 20. The outer wall of the third rotating rod 20 is rotationally connected with a scraper 21, and the scraper 21 is slidably connected between the barrel 2 and the filter barrel 3. Since two third driving motors 19 are welded to the side of the mounting frame 1, the output shafts of the two third driving motors 19 can drive the two third rotating rods 20 to rotate. The outer walls of the two rotating third rotating rods 20 can drive the scraper 21 to slide on the inner wall of the barrel 2 and the outer wall of the filter barrel 3, so that the scraper 21 can scrape the materials falling inside the barrel 2 into the inside of the material receiving frame 18, thus facilitating the collection of materials.

[0024] Working principle: During operation, the barrel 2 welded to the inner side of the mounting frame 1 enables the first driving motor 4 welded to the side of the mounting frame 1 to drive the first rotating rod 5 to rotate. Thus, the rotating first rotating rod 5 can drive the filter barrel 3 to rotate on the inner wall of the barrel 2. At the same time, a rotating member 6 rotationally connected to the inner wall of one side of the filter barrel 3 can be welded with a rotating cylinder 7, so that the opened feed slot 11 can penetrate the outer walls of the barrel 2 and the rotating cylinder 7. For the second driving motor 8 installed on the side of the mounting frame 1, the output shaft of the second driving motor 8 can drive the second rotating rod 9 to rotate. The rotating second rotating rod 9 can drive the stirring rod 10 to agitate the materials. At the same time, the driving directions of the first driving motor 4 and the second driving motor 8 are opposite, thus facilitating the sieving of the materials and accelerating the sieving speed. Since a slide plate 13 is welded to the inner wall of the rotating cylinder 7, the incoming materials can enter the inner wall of the filter barrel 3 through the outer wall of the slide plate 13. For the three discharge slots 14 opened on the outer wall of the barrel 2, discharge plates 15 are installed on the inner walls of the discharge slots 14 so that the materials can be discharged through the discharge plates 15. For the connecting cylinder 16 welded to the bottom of the discharge plate 15, the materials can be collected through the material receiving frame 18. For the materials adhering to the inner wall of the barrel 2, the two third driving motors 19 welded to the side of the mounting frame 1 can drive the two third rotating rods 20 to rotate. At the same time, the two third rotating rods 20 can limit the scraper 21. Thus, the two rotating third rotating rods 20 can drive the scraper 21 to scrape the materials adhering to the inner wall of the barrel 2 into the inside of the material receiving frame 18 through the discharge slot 14. At the same time, the two third driving motors 19 are reversible motors, and the two third driving motors 19 can cyclically drive the scraper 21 to move back and forth, thus facilitating the use of the device.
