DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example: A crushing device for rare earth smelting, see Figure 1-4, including a chassis 1, the right side of the chassis 1 is an open setting, a crushing box 2 is connected to the top left side of the chassis 1, and two groups of upper and lower crushing wheels 3 are rotatably connected in the crushing box 2, two crushing wheels 3 form a group, and the two crushing wheels 3 in each group are symmetrically arranged, and the gap between the two upper crushing wheels 3 is larger than the gap between the two lower crushing wheels 3, so that large particles of rare earth are preliminarily crushed by the upper crushing wheel 3, and smaller particles of rare earth are further refined and crushed by the lower crushing wheel 3. This graded crushing method can better adapt to rare earths of different particle sizes and improve the crushing effect. Gear boxes 31 are provided on the front and rear sides of the crushing box 2, and four output shafts on the gear box 31 are respectively connected to the four crushing wheels 3. The lower right side of the crushing box 2 is connected to a guide The guide frame 7 is inclined with the left side higher than the right side. A fan 21 is embedded in the lower part of the left wall of the crushing box 2. The right side of the guide frame 7 is rotatably connected to the rolling cylinder 4 through the rotating shaft 41. The gap between the highest point of the rolling cylinder 4 and the top of the inner side of the guide frame 7 is less than 2mm, and the gap between the lowest point of the rolling cylinder 4 and the bottom of the inner side of the guide frame 7 is less than 2mm. The end of the rotating shaft 41 extends out of the guide frame 7. A servo motor 5 is installed on the front side of the top of the chassis 1. The output shaft of the servo motor 5 is connected to the rotating shaft 41. A feed port 22 is opened on the right side of the top of the chassis 1. The feed port 22 is located directly below the rolling cylinder 4. A connecting frame 8 that can move up and down is slidably connected to the top of the guide frame 7. The bottom left side of the connecting frame 8 is hinged with two sets of front and rear swing plates 1 1. Two swing plates 11 form a group. The two swing plates 11 in each group are symmetrically arranged front and back. The lower part of the swing plate 11 is rotatably connected with a rolling wheel 12. The rolling wheel 12 and the swing plate 11 are both located in the guide frame 7, and the rolling wheel 12 contacts the inner bottom of the guide frame 7. A driving assembly is provided between the rotating shaft 41 and the connecting frame 8. When the rotating shaft 41 rotates, the connecting frame 8 is driven to reciprocate up and down by the driving assembly. The driving assembly includes a disc 6 connected to the rear end of the rotating shaft 41. A connecting rod I9 is ​​hinged at an eccentric position on the rear side of the disc 6. A connecting rod II10 is hinged on the connecting rod I9. The connecting rod II10 is hinged to the connecting frame 8. Two connecting rods 15 are symmetrically connected to the right side of the bottom of the connecting frame 8. A mesh pressure plate is connected between the bottom ends of the two connecting rods 15. 13. The mesh pressure plate 13 is located between the rolling wheel 12 and the rolling drum 4. A cleaning brush 16 is connected to the top right side of the chassis 1. The cleaning brush 16 is in contact with the rolling drum 4. The rare earth adhering to the rolling drum 4 can be cleaned by the cleaning brush 16 to avoid the rare earth staying and accumulating on the rolling drum 4. A collecting box 14 for collecting rare earths is slidably connected in the chassis 1. A handle is connected to the right outer wall of the collecting box 14. Wheels are installed at the four corners of the bottom of the collecting box 14. The handle and the wheel cooperate to facilitate the collection box 14. The top of the collecting box 14 fits with the inner top of the chassis 1, which can effectively seal and collect the rare earth, thereby avoiding fine rare earth particles from flying around, thereby ensuring the cleanliness of the working environment and the safety of the operators.

[0021] First, the output shaft of the front gear box 31 is connected to the output shaft of the external motor to realize power transmission and conversion, thereby driving the left and right crushing wheels 3 to rotate in opposite directions, and then the rare earth raw materials to be crushed are sent to the crushing box 2 through the conveyor, and the rare earth is preliminarily crushed by the upper crushing wheel 3, and the smaller particles of rare earth are further refined and crushed by the lower crushing wheel 3, and the refined and crushed rare earth is blown into the guide frame 7 by the fan 21, and the rare earth slides to the right along the inner bottom of the guide frame 7. The servo motor 5 is controlled to work to drive the rotating shaft 41 to drive the rolling drum 4 and the disc 6 to rotate. The rotation of the disc 6 can make the connecting frame 8 reciprocate up and down through the cooperation of the connecting rod Ⅰ9 and the connecting rod Ⅱ10. Since the rolling wheel 12 is in contact with the inner bottom of the guide frame 7 and cannot move downward, the lower part of the swing plate 11 cannot move downward, so the connecting frame 8 moves downward so that the two swing plates 11 in each group swing outward and away from each other, thereby making the two rolling wheels 12 in each group move away from each other; when the connecting frame 8 pulls the upper part of the swing plate 11 to move up and reset, under the action of gravity, the two swing plates 11 in each group swing inward and approach each other, thereby making the two rolling wheels 12 in each group approach each other, so that the rolling wheel 12 can move back and forth and rotate along the inner bottom of the guide frame 7, so that the refined and crushed rare earth can be rolled and ground to further refine and homogenize the crushed rare earth, thereby obtaining a more ideal crushing effect. The rotation of the rolling drum 4 can perform secondary rolling and grinding on the rare earth to further refine and homogenize the rare earth after rolling and grinding, thereby obtaining a more ideal crushing effect. The rolled and ground rare earth is then discharged into the collecting box 14 through the feed port 22 for collection; the connecting frame 8 moves up and down, driving the mesh pressure plate 13 to move up and down through the connecting rod 15. The up and down movement of the mesh pressure plate 13 can knock on the inner bottom of the guide frame 7, so that the guide frame 7 vibrates to disperse the rare earth therein, and the up and down movement of the mesh pressure plate 13 can also disperse the rare earth in the guide frame 7, so as to avoid the rare earth being concentrated in one place and affecting the subsequent rolling and grinding effect of the rolling drum 4 on the rare earth.

It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
