[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1-4 The shown ball mill feeding device for preventing material blocking comprises a box body 1, an L-shaped column is fixedly installed on the side of the box body 1, a rotating motor 2 is fixedly installed on the top of the L-shaped column, a rotating shaft is fixedly installed on the output end of the rotating motor 2, one end of the rotating shaft passes through the inner wall of the box body 1 and a turntable is fixedly installed, an annular screen plate 10 is fixedly installed on the side of the turntable, two rotating motors 13 are fixedly installed on the other side of the box body 1, the output ends of the two rotating motors 13 pass through the side of the box body 1 and are fixedly connected to two crushing rollers 12, a plurality of evenly arranged right-angled triangular blocks 3 are fixedly sleeved on the rotating shaft, a sliding hole is opened on the inner wall of the top side of the box body 1, a flapping mechanism is installed in the sliding hole, and the flapping mechanism is installed in conjunction with the plurality of right-angled triangular blocks 3.

[0022] By means of the above structure: by starting two rotating motors 13, the two crushing rollers 12 are rotated, so that the material is crushed to facilitate the later feeding. At the same time, the material falls on the annular screen plate 10, and the material is filtered through the annular screen plate 10. When it is found that the material is accumulated and blocked, the rotating motor 2 is started at this time. The output end of the rotating motor 2 drives the rotating shaft and the turntable to rotate, and then the annular screen plate 10 is rotated, so that the material rolls on the inner wall of the annular screen plate 10, which is convenient for filtering and not easy to accumulate. At the same time, a plurality of evenly arranged right-angle triangle blocks 3 are used to make the beating mechanism move up and down to beat the annular screen plate 10.

[0023] like Figure 1 , Figure 3 As shown, the beating mechanism includes a slide rod 8 slidably installed in the slide hole, both ends of the slide rod 8 extend outside the slide hole, an arc plate 9 is fixedly installed on the bottom end of the slide rod 8, the bottom of the arc plate 9 contacts the top of the annular screen plate 10, a rectangular pressure plate 6 is fixedly installed on the top of the slide rod 8, a U-shaped rod 5 is fixedly installed on the top of the rectangular pressure plate 6, an arc block 4 is fixedly installed on the bottom end of the U-shaped rod 5, and the bottom end of the arc block 4 contacts the side of one of the right-angled triangle blocks 3; the beating mechanism also includes a spring 7 sleeved on the slide rod 8, the top and bottom ends of the spring 7 are respectively fixedly installed on the bottom of the rectangular pressure plate 6 and the top of the box body 1. After starting the rotating motor 2, the rotation of the rotating shaft drives the multiple right-angled triangular blocks 3 to rotate. When the inclined side of the right-angled triangular block 3 squeezes the arc block 4, the arc block 4 moves upward, and then the U-shaped rod 5, the rectangular pressure plate 6, the arc plate 9 and the slide bar 8 move upward, and the spring 7 is stretched to produce deformation. When the inclined side of the right-angled triangular block 3 is separated from the arc block 4, the arc block 4 contacts the straight edge of the right-angled triangular block 3. Under the reaction of the spring 7, the U-shaped rod 5, the rectangular pressure plate 6, the arc plate 9 and the slide bar 8 return to their original state, so that the arc plate 9 slaps the top of the annular screen plate 10 to prevent the material from being blocked in the holes on the annular screen plate 10.

[0024] like Figure 1 , Figure 4 As shown, an L-shaped plate 14 is fixedly installed on the side of the box body 1, a feed box 15 is fixedly installed on the top of the L-shaped plate 14, and a connected feed pipe 16 is fixedly installed on the side of the feed box 15 close to the box body 1. The feed pipe 16 extends to the inner wall of the box body 1 and is located above the two crushing rollers 12. With this structure, the material can be sent to the top of the two crushing rollers 12, which is convenient for the material to be crushed.

[0025] like Figure 2 , Figure 3As shown, the two crushing rollers 12 are rotatably connected to the annular plate 11 at one end away from the rotating motor 13, and an annular groove is provided on the side of the turntable, and the annular plate 11 is rotatably installed in the annular groove. With this structure, the two crushing rollers 12 can be supported, and the two crushing rollers 12 will not rotate with the rotation of the annular screen plate 10.

[0026] like Figure 4 As shown, a discharge port is provided on the inner wall of the bottom side of the box body 1, so as to facilitate the feeding of the crushed and screened materials into the ball mill.

[0027] like Figure 2 As shown, a rectangular hole is provided on the inner wall of the box body 1, and a switch door is installed in the rectangular hole. The annular sieve plate 10 can be cleaned by opening the switch door.

[0028] Working principle: When in use, feed the material through the feed box 15, and the material enters the top of the two crushing rollers 12 through the feed pipe 16. By starting the two rotating motors 13, the two crushing rollers 12 rotate, thereby crushing the material, which is convenient for later feeding;

[0029] At the same time, the material falls on the annular sieve plate 10 and is filtered through the annular sieve plate 10. When it is found that the material is accumulated and blocked, the rotating motor 2 is started at this time, and the output end of the rotating motor 2 drives the rotating shaft and the turntable to rotate, thereby rotating the annular sieve plate 10, so that the material rolls on the inner wall of the annular sieve plate 10, which is convenient for filtering and not easy to accumulate;

[0030] At the same time, the rotation of the rotating shaft drives multiple right-angled triangle blocks 3 to rotate. When the inclined side of the right-angled triangle block 3 squeezes the arc block 4, the arc block 4 moves upward, and then the U-shaped rod 5, the rectangular pressure plate 6, the arc plate 9 and the slide bar 8 move upward, and the spring 7 is stretched to produce deformation. When the inclined side of the right-angled triangle block 3 is separated from the arc block 4, the arc block 4 contacts the straight edge of the right-angled triangle block 3. Under the reaction of the spring 7, the U-shaped rod 5, the rectangular pressure plate 6, the arc plate 9 and the slide bar 8 return to their original state, so that the arc plate 9 slaps the top of the annular screen plate 10 to prevent the material from being blocked in the holes on the annular screen plate 10, and the ball mill can be fed through the discharge port.

[0031] 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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
