[0002] A ball mill can grind materials into very fine particle sizes, meeting the requirements of many industrial productions for fine powders. It can not only grind but also fully mix different components of materials evenly during the grinding process, with high processing capacity, which can meet the needs of large-scale industrial production.

[0003] After different materials are ground by a ball mill, there may be significant differences in their particle sizes, humidity, and viscosity characteristics. A specific discharge port structure can better cope with these differences to ensure the smooth discharge of various materials. A reasonable design of the discharge port structure can reduce the resistance and friction of materials during the discharging process, thereby reducing energy consumption.

[0004] At present, the discharge ports of most ball mills on the market have uneven particle sizes during discharging. Over-sized particles or agglomerated materials may get stuck in the discharge port, hindering normal discharging, resulting in the inability of materials to be discharged in time, interrupting the working process of the ball mill, and forcing production to stagnate, thus reducing work efficiency.

[0031] 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 the embodiments. Based on the embodiments in 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.

[0032] Refer to Figure 1 , Figure 2 and Figure 3, an embodiment provided by the present utility model: a discharge port structure of a ball mill, including a bracket 1, fixed frames 3 are fixedly connected to the tops of both brackets 1, a drum 4 is rotatably connected to the adjacent sides of both fixed frames 3, a plurality of filter holes 5 are equidistantly arranged in the middle of the outer wall of the drum 4, circular grooves 6 are arranged on the left and right sides of the outer wall of the drum 4, two circular grooves 6 are both slidably connected with a ring 7, the adjacent sides of the two rings 7 are fixedly connected to the same housing 8, a cavity 9 is arranged inside the housing 8, a discharge hole 10 is arranged at the bottom of the housing 8, a fixing plate 11 is fixedly connected to the right side of the bracket 1, a vibrator 12 is fixedly connected to the top right end of the fixing plate 11, the output end of the vibrator 12 is fixedly connected to the bottom of the housing 8, a feed inlet 13 is communicated with the left side of the drum 4, a transmission mechanism 2 is arranged on the right side of the bracket 1, and the transmission mechanism 2 is used to provide power for the equipment. The two rings 7 slide inside the corresponding circular grooves 6 respectively, and the sizes of the rings 7 and the circular grooves 6 are the same;

[0033] Specifically, the material needs to be first fed into the rotating drum 4 through the feed inlet 13. The drum 4 grinds the internal material by rotation. When the particle size of the material reaches a certain fineness, it will move outward of the drum 4 due to the centrifugal force generated by rotation. At this time, the filter holes 5 screen the internal material, and the fine particles after grinding enter the cavity 9 inside the housing 8 through the filter holes 5. The rotation of the drum 4 will drive the circular grooves 6 to rotate. Since the rings 7 are limited by the rear fixing blocks 19 and the cross plate 18 and will not rotate with the drum 4, the material in the cavity 9 will be discharged through the discharge hole 10 due to the action of gravity. Turn on the switch 15 to start the vibrator 12, so that the discharge hole 10 vibrates to promote the smooth discharge of the material.

[0034] Referring to Figure 3 , Figure 4 and Figure 5 , the transmission mechanism 2 includes a chute 201, the chute 201 is arranged on the top of the right bracket 1, a toothed ring 202 is slidably connected inside the chute 201, an extension plate 203 is fixedly connected to the top right side of the right bracket 1, a motor 204 is fixedly connected to the top of the extension plate 203, a rotating shaft 205 is fixedly connected to the output end of the motor 204, a gear 206 is fixedly connected to the left end of the rotating shaft 205, the gear 206 is meshed with the toothed ring 202, a buffer box 207 is fixedly connected to the bottom of the discharge hole 10, a plurality of springs 208 are equidistantly fixedly connected inside the buffer box 207, the top ends of the plurality of springs 208 are fixedly connected to the same inclined plate 209, a discharge hole 10 is arranged at the bottom of the housing 8, and the sizes of the discharge hole 10 and the buffer box 207 are the same;

[0035] Specifically, turn on the switch 15 to start the motor 204, which drives the rotation of the rotating shaft 205, causing the gear 206 to rotate accordingly. Then, the movement of the rack drives the synchronous rotation of the drum 4. When the material is discharged through the discharge hole 10, the falling of the material will enter the buffer box 207 and exert a downward impact force on the inclined plate 209. This impact force will compress the spring 208, causing the spring 208 and the inclined plate 209 to move downward together to slow down the impact, thereby protecting the discharging device and extending its service life.

[0036] Refer to Figure 1 and Figure 5 , a triangular frame 14 is fixedly connected to the bottom of the fixing plate 11. The left side of the triangular frame 14 is fixedly connected to the right side of the bracket 1. A switch 15 is fixedly connected to the front side of the bracket 1. The switch 15 is electrically connected to the motor 204 and the vibrator 12 respectively;

[0037] Specifically, the triangular frame 14 can reinforce the fixing plate 11 to make the fixing plate 11 more stable when the vibrator 12 works. The switch 15 can freely control the operation of the motor 204 and the vibrator 12.

[0038] Refer to Figure 1 and Figure 2 , bottom plates 16 are fixedly connected to the bottoms of the two brackets 1. Rubber pads 17 are fixedly connected to the bottoms of the two bottom plates 16. The adjacent sides of the rear ends of the two brackets 1 are fixedly connected to the same cross plate 18. A fixing block 19 is fixedly connected to the front side of the cross plate 18. The front side of the fixing block 19 is fixedly connected to the rear side of the outer shell 8;

[0039] Specifically, the bottom plates 16 and the rubber pads 17 can keep the brackets 1 stable during operation. The cross plate 18 and the fixing block 19 can fix the outer shell 8 when the drum 4 rotates so that the outer shell 8 will not rotate accordingly.

[0040] Working principle: When using the ball mill, the material needs to be first fed into the drum 4 from the feed port 13. At this time, the drum 4 rotates to grind the internal material. When the particles are ground to a certain size, they move outward due to the centrifugal force generated by the rotation. At this time, the filter holes 5 filter the material in the drum 4. The ground small-particle material enters the cavity 9 opened inside the outer shell 8 through the filter holes 5. At this time, the drum 4 rotates to drive the circular groove 6 to rotate. At the same time, because of the limiting and fixing effect of the fixing block 19 and the cross plate 18 on the rear side of the outer shell 8, the ring 7 and the outer shell 8 will not rotate with the drum 4. At this time, the material inside the cavity 9 will slide downward and discharge through the discharge hole 10. At the same time, when too much material is discharged, turn on the switch 15 to make the vibrator 12 work, making the discharge hole 10 vibrate and facilitating the discharge of the material;

[0041] And when the roller 4 needs to rotate, the switch 15 is turned on at this time to make the motor 204 work to drive the rotation of the rotating shaft 205, so that the gear 206 rotates to drive the rack to rotate, and at the same time the roller 4 rotates accordingly. When the material is discharged from the discharge hole 10, the material enters the buffer box 207 at this time, and the impact force of the material contacting the inclined plate 209 downward will squeeze the spring 208, causing the spring 208 to contract and drive the inclined plate 209 to move downward, reducing the impact force so as to protect the discharging device and extend its service life.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
