Specific embodiments
[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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-5, an embodiment provided by the present utility model: a steel ball replenishing device for a ball mill, comprising a filling box 1 and a support plate 2. A support plate 2 is arranged inside the filling box 1, and a blanking groove 22 is arranged on one side of the support plate 2. A blanking pipe 23 is arranged at the bottom of the support plate 2 corresponding to the position of the blanking groove 22, and the other end of the blanking pipe 23 extends outside the filling box 1 and is fixedly connected to a discharge pipe 10. Connecting blocks are evenly and staggeredly arranged inside the discharge pipe 10, and inclined plates 8 are connected to the connecting blocks of the discharge pipe 10 through rotating shafts. Springs 9 are arranged at the middle positions inside the inclined plates 8, and the other ends of the springs 9 are connected to the inner wall of the discharge pipe 10. An annular baffle 7 is arranged on the outside of the blanking pipe 23 at the top of the discharge pipe 10, and a clamping cover 11 is arranged on the annular groove at the top of the annular baffle 7. Parallel slide bars 14 are arranged on both sides inside the clamping cover 11, and sliding blocks 16 are arranged at both ends of the slide bars 14. Elastic clamping plates 15 are arranged between the sliding blocks 16 corresponding to both ends of the slide bars 14. Uniform threaded holes 17 are arranged on both sides of the clamping cover 11 corresponding to the positions of the slide bars 14, and threaded rods 18 are connected to the threaded holes 17 outside the sliding blocks 16 on both sides of the clamping cover 11 through threads. A rotating shaft 21 is arranged at the middle position on the top of the support plate 2, and a rotating table 3 is arranged on the rotating shaft 21 on the top of the support plate 2. Steel ball grooves 19 are evenly arranged on the rotating table 3, and the size of the steel ball grooves 19 is the same as that of the blanking groove 22. A protective cover 20 is arranged on the outside of the rotating shaft 21 at the top of the rotating table 3, and the tops of the steel ball grooves 19 on the rotating table 3 are all funnel-shaped. A rotating motor 4 is arranged at the middle position on the bottom of the support plate 2, and the output end of the rotating motor 4 penetrates through the support plate 2 and is connected to the rotating shaft 21, enabling the staff to lift the annular baffle 7 to an appropriate height according to the depth of the machine, then insert the blanking pipe 23 and the discharge pipe 10 into the filling port, so that the annular baffle 7 supports on the outside of the filling port. Then, the sliding blocks 16 can be moved on the slide bars 14 to make the elastic clamping plates 15 between the sliding blocks 16 closely fit the blanking pipe 23. Then, take the threaded rod 18 and move it to the threaded hole 17 outside the sliding block 16, and rotate and screw the threaded rod 18 into the threaded hole 17 to limit the sliding block 16 and prevent the elastic clamping plate 15 from moving. Loosening the clamping of the blanking pipe 23 can prevent the blanking pipe 23 from shaking when filling steel balls, making the impact force of the steel balls falling greater. When filling is required, the staff can start the rotating motor 4 to drive the rotating table 3 on the rotating shaft 21 to rotate. When the steel ball grooves 19 on the rotating table 3 rotate to the position of the blanking groove 22, blanking is carried out. According to the number of steel balls to be filled, the rotating table 3 can be rotated a corresponding number of times for quantitative filling, preventing overfilling and underfilling and affecting the grinding effect. When the steel balls enter the discharge pipe 10 through the blanking pipe 23, the impact force of the steel balls can be buffered through the action of the inclined plates 8 and the springs 9, preventing the steel balls from falling and impacting the inside of the machine, resulting in damage to its inside;
[0022] On the inner wall of the filling box 1 outside the rotary table 3, there is an annular block 5, and sliding balls are evenly arranged on the inner side of the annular block 5, and the sliding balls on the inner side of the annular block 5 are all in contact with the rotary table 3, so that when the rotary table 3 rotates, it can rotate stably through the action of the annular block 5 and the sliding balls;
[0023] Support blocks 6 are arranged around the bottom of the filling box 1, support covers 12 are arranged at the bottoms of the support blocks 6, pulleys are arranged at the bottoms of the support covers 12, telescopic rods 13 are arranged in the support covers 12, and the output ends of the telescopic rods 13 all penetrate through the support covers 12 and are connected to the support blocks 6, so that the staff can move the device to the filling place, and then can start the telescopic rod 13 to drive the filling box 1 on the top of the support block 6 to be lifted, facilitating the adjustment of the position of the corresponding filling port.
[0024] When the embodiment of the present application is in use, the staff moves the device to the filling place, and then can start the telescopic rod 13 to drive the filling box 1 on the top of the support block 6 to be lifted, facilitating the adjustment of the position of the corresponding filling port. Then, according to the depth of the machine, the annular baffle 7 is lifted to an appropriate height, and then the feeding pipe 23 and the discharging pipe 10 are inserted into the filling port, so that the annular baffle 7 supports outside the filling port. Then, the sliding block 16 can be moved on the sliding rod 14, so that the elastic clamping plate 15 between the sliding blocks 16 is closely attached to the feeding pipe 23. Then, the threaded rod 18 is taken and moved to the threaded hole 17 outside the sliding block 16, and the threaded rod 18 is rotated and screwed into the threaded hole 17 to limit the sliding block 16, preventing the elastic clamping plate 15 from moving, and releasing the clamping of the feeding pipe 23, which can prevent the feeding pipe 23 from shaking when filling steel balls, making the impact force of the steel balls falling greater. When filling is required, the staff can start the rotary motor 4 to drive the rotary table 3 on the rotary shaft 21 to rotate. The rotary table 3 rotates stably through the action of the annular block 5 and the sliding balls. When the steel ball groove 19 on the rotary table 3 rotates to the feeding groove 22, feeding is carried out. According to the number of steel balls to be filled, the rotary table 3 can be rotated correspondingly several times for quantitative filling, preventing overfilling and underfilling, which may affect the grinding effect. When the steel balls enter the discharging pipe 10 through the feeding pipe 23, the steel balls can buffer the impact force through the action of the inclined plate 8 and the spring 9, preventing the steel balls from falling and impacting the inside of the machine, resulting in damage to its inside.
