The device is fixedly installed through the fixed support frame 2, which improves the convenience of fixed installation of the ball adding device, reduces the difficulty of maintenance of the ball adding device, improves the convenience of adding balls to the ball mill, and adds grinding balls to the ball mill through the grinding ball storage box 1.

[0024] Please refer again Figure 1 、 Figure 2 and Figure 3 A ball discharging mechanism 3 is provided at the bottom of the grinding ball storage box 1. The ball discharging mechanism 3 includes a grinding ball chute 301 fixedly connected to the grinding ball storage box 1. The grinding balls of appropriate size are transported to the interior of the ball mill through the grinding ball chute 301, thereby improving the convenience of adding balls to the ball mill.

[0025] A grinding ball slide 302 is hingedly connected to the interior of the grinding ball chute 301, and a vibration plate 303 is fixedly connected to the middle of the grinding ball slide 302. When the vibration plate 303 is energized to generate vibration, the grinding ball slide 302 can be driven to vibrate synchronously, so that the vibration plate 303 can better transport the grinding balls into the ball mill, preventing the grinding balls from being stuck in the grinding ball chute 301 and causing the grinding ball chute 301 to be blocked, thereby improving the convenience of adding balls to the ball mill.

[0026] The vibration plate 303 can be made of a piezoelectric ceramic sheet. When voltage is applied to the piezoelectric ceramic, mechanical deformation will occur as the voltage and frequency change. Using this principle, a vibrator is formed by two piezoelectric ceramics or one piezoelectric ceramic and a metal sheet.

[0027] The surface of the grinding ball slide 302 is fixedly connected to a support rod 304, and the support rod 304 passes through the grinding ball chute 301 and is slidably connected to the chute on the surface of the grinding ball chute 301. The surface of the support rod 304 is fixedly connected to a telescopic spring 305, and the top of the telescopic spring 305 is fixedly connected to the grinding ball chute 301. The telescopic spring 305 and the support rod 304 provide support and fixation for the grinding ball slide 302, thereby improving the convenience of the operation of the grinding ball slide 302. The telescopic spring 305 can amplify the vibration of the grinding ball slide 302, increase the up and down vibration amplitude of the grinding ball slide 302, reduce the probability of the grinding balls getting stuck inside the grinding ball chute 301, and improve the smoothness of the grinding ball slide 302 in transmitting the grinding balls.

[0028] If it is necessary to add balls to multiple ball mills, the bottom end of the ball chute 301 can be connected to a steering device, and grinding balls can be added to two or more ball mills through the outlet of the steering device. Then, the ball adding device can add grinding balls to multiple ball mills in sequence, thereby improving the convenience of adding grinding balls.

[0029] Please refer again Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The interior of the grinding ball storage box 1 is provided with a ball dividing mechanism 4 arranged at equal intervals. The ball dividing mechanism 4 includes a grinding ball classification storage bin 401, a stirring rod 403 and a linkage sleeve 406. The grinding ball classification storage bin 401 is opened inside the grinding ball storage box 1. Grinding balls of different sizes are stored through a plurality of grinding ball classification storage bins 401, thereby improving the convenience of grinding ball storage and adding balls. The grinding balls inside the grinding ball classification storage bin 401 are stirred by the stirring rod 403 to avoid the grinding balls from getting stuck with each other, thereby improving the convenience and smoothness of grinding ball adding.

[0030] The surface of the linkage sleeve 406 is fixedly connected to the ball outlet wheel 404, which is controlled by the linkage sleeve 406 to rotate inside the grinding ball classification storage bin 401, and the grinding balls inside the grinding ball classification storage bin 401 are quantitatively transported out, thereby improving the grinding ball adding efficiency.

[0031] The stirring rod 403 is fixed on the surface of the power transmission shaft 501, and the stirring rod 403 is located directly above the ball outlet wheel 404. The surface of the grinding ball storage box 1 is rotatably connected to a sealing cover plate 409 adapted to the grinding ball classification storage bin 401. The grinding ball storage box 1 is fixedly connected to a scale indicator plate 402 adapted to the grinding ball classification storage bin 401. The sealing cover plate 409 is used to seal the grinding ball classification storage bin 401 to improve the stability of the grinding balls stored in the grinding ball classification storage bin 401. The scale indicator plate 402 is used to display the number of grinding balls inside the grinding ball classification storage bin 401, so that the number of grinding balls inside the grinding ball classification storage bin 401 can be more intuitively understood. When the number of grinding balls is small, grinding balls can be added to the grinding ball classification storage bin 401 in time.

[0032] The surface of the ball discharge wheel 404 is provided with circumferentially arranged quantitative ball discharge bins 405, through which the grinding balls are stored. When the ball discharge wheel 404 rotates, the quantitative ball discharge bins 405 transport a quantitative amount of grinding balls from the grinding ball classification storage bin 401 to the grinding ball chute 301 by controlling the number of revolutions of the ball discharge wheel 404, thereby improving the quantitative discharge of the grinding balls.

[0033] The surface of the grinding ball classification storage bin 401 is fixedly connected with a double-sided damping ring 407. The double-sided damping ring 407 is a mature technology. The present application can use existing equipment that can limit the linkage sleeve 406. The outer ring of the double-sided damping ring 407 is connected to the inner ring of the ball outlet wheel 404 for damping rotation, and the inner ring of the double-sided damping ring 407 is connected to the surface of the linkage sleeve 406 for damping rotation. When the power transmission block 410 is not engaged with the connecting clamping ring 408, the ball outlet wheel 404 and the linkage sleeve 406 are positioned by the double-sided damping ring 407 to prevent the ball outlet wheel 404 from rotating, thereby improving the accuracy of grinding ball transportation.

[0034] Please refer again Figure 4 and Figure 5 The surface of the linkage rotating shaft 506 is fixedly connected with equidistantly arranged power transmission blocks 410, and the interior of the linkage sleeve 406 is fixedly connected with connecting snap rings 408. The connecting snap rings 408 are equally arranged inside the linkage sleeve 406. The power transmission blocks 410 are engaged with the connecting snap rings 408. By engaging the power transmission blocks 410 with different connecting snap rings 408, the linkage rotating shaft 506 controls the rotation of the linkage sleeve 406, thereby improving the stability and convenience of the rotation of the linkage sleeve 406.

[0035] If the power transmission block 410 moves to the left, the power transmission block 410 is engaged with the leftmost connecting snap ring 408, and at the same time the remaining power transmission blocks 410 are disengaged from the connecting snap ring 408. The remaining linkage sleeves 406 can be positioned by the double-sided damping ring 407, and the linkage sleeves 406 can be limited to prevent the linkage sleeves 406 from rotating at will, thereby improving the accuracy of the grinding balls.

[0036] See also Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 The grinding ball storage box 1 is provided with a power mechanism 5 inside, and the power mechanism 5 includes a power delivery shaft 501 and a linkage rotating shaft 506. The power delivery shaft 501 is rotatably connected to the grinding ball storage box 1, and a power device for controlling the rotation of the power delivery shaft 501 is fixedly connected to the surface of the grinding ball storage box 1. The power device is a mature technology. The present application can use the existing equipment that can control the rotation of the power delivery shaft 501, and the linkage rotating shaft 506 is movably connected to the grinding ball storage box 1. The stirring rod 403 is controlled to rotate by the power delivery shaft 501 to stir the grinding balls inside the grinding ball classification storage bin 401. The corresponding linkage sleeve 406 is controlled to rotate by the linkage rotating shaft 506, so that the ball outlet wheel 404 delivers the selected grinding balls quantitatively, and adds grinding balls of appropriate size to the ball mill according to demand, thereby improving the stability and convenience of adding grinding balls.

[0037] One end of the power transmission shaft 501 is fixedly connected to a power sprocket 502, and the power sprocket 502 is connected to a transmission sprocket 503 through a chain transmission. The middle part of the transmission sprocket 503 is assembled and connected with a linkage member 504. The surface of the grinding ball storage box 1 is fixedly connected to a fixed ring 505, and the linkage member 504 is rotatably connected to the fixed ring 505 through a bearing. The linkage member 504 is positioned and fixed by the fixed ring 505 and the bearing to improve the rotation stability of the linkage member 504. The transmission sprocket 503 can be controlled to rotate synchronously by the power sprocket 502 and the chain. The linkage rotating shaft 506 is controlled to rotate by the transmission sprocket 503 and the linkage member 504, so that the linkage rotating shaft 506 rotates synchronously with the power transmission shaft 501.

[0038] The linkage member 504 is sleeved on the outside of the linkage rotating shaft 506, and a sliding groove 507 is provided on the surface of the linkage rotating shaft 506. The linkage member 504 is fixedly connected to the inside of the linkage block 508, and the linkage block 508 is slidably connected to the sliding groove 507. The surface of the linkage member 504 is movably connected to the protective shell 517, which is sleeved on the outside of the chain and fixedly connected to the grinding ball storage box 1. The linkage member 504 and the linkage rotating shaft 506 are assembled together through the linkage block 508 and the sliding groove 507. When the linkage rotating shaft 506 moves laterally, the linkage member 504 and the linkage rotating shaft 506 maintain a continuous and stable connection state. The rotation of the linkage member 504 can drive the linkage rotating shaft 506 to rotate synchronously, thereby improving the stability of the rotation of the linkage rotating shaft 506. The protective shell 517 provides sealing and protection for the power sprocket 502 and the transmission sprocket 503, thereby improving the stability and convenience of the sprocket transmission.

[0039] The surface of the grinding ball storage box 1 is fixedly connected with a hydraulic push rod 514. The hydraulic push rod 514 is a mature technology. The present application can use an existing device that provides sufficient tensioning force for the chain tensioner 513. The output end of the hydraulic push rod 514 is clamped with a positioning frame 512. The internal rotation of the positioning frame 512 is connected to the chain tensioner 513, and the chain tensioner 513 is connected to the chain transmission. The surface of the positioning frame 512 is fixedly connected with a sliding block 515. The surface of the grinding ball storage box 1 is fixedly connected with a positioning groove 516, and the sliding block 51 5 is slidably connected to the positioning groove 516, and the hydraulic push rod 514 provides thrust to the positioning frame 512. The positioning frame 512 drives the chain tensioner 513 to squeeze the chain, so that the chain maintains a suitable tension state and improves the stability of the chain transmission. The positioning frame 512 is positioned by the sliding block 515 and the positioning groove 516, so that the positioning frame 512 can only slide horizontally, preventing the positioning frame 512 from swinging longitudinally, improving the stability of the horizontal sliding of the positioning frame 512, and thus allowing the chain tensioner 513 to provide stable tension on the chain.

[0040] The surface of the grinding ball storage box 1 is fixedly connected to a fixed plate 510, and the middle part of the fixed plate 510 is slidably connected to a rotating shaft positioning frame 509, and the two ends of the rotating shaft positioning frame 509 are rotatably connected to the two ends of the linked rotating shaft 506, and the surface of the fixed plate 510 is fixedly connected to an electric push rod 511, and the output end of the electric push rod 511 is fixedly connected to the rotating shaft positioning frame 509 by bolts. The electric push rod 511 is a mature technology. The present application can adopt the existing equipment for controlling the movement of the rotating shaft positioning frame 509, and position the rotating shaft positioning frame 509 through the fixed plate 510 to improve the stability of the lateral sliding of the rotating shaft positioning frame 509, and provide thrust to the rotating shaft positioning frame 509 through the electric push rod 511 to adjust the position of the rotating shaft positioning frame 509 laterally, thereby controlling the power transmission block 410 to engage with different connecting clamps 408, thereby improving the stability of the linked rotating shaft 506 in controlling the rotation of the linked sleeve 406.

[0041] Both ends of the power transmission block 410 are arc-shaped, and the corners of the connecting retaining ring 408 are arc-shaped. The arc shape makes it easier for the power transmission block 410 to be inserted into the connecting retaining ring 408. When the power transmission block 410 needs to be inserted into the inside of the connecting retaining ring 408, the linkage rotating shaft 506 controls the power transmission block 410 to rotate slowly, so that the power transmission block 410 rotates on the surface of the connecting retaining ring 408. The two ends of the linkage rotating shaft 506 are fixed by the rotating shaft positioning frame 509, and the rotating shaft positioning frame 509 is controlled by the electric push rod 511 to move horizontally, driving the linkage rotating shaft 506 to move horizontally, so that the power transmission block 410 can be inserted into the inside of the connecting retaining ring 408 faster, thereby improving the accuracy and speed of the connection between the connecting retaining ring 408 and the power transmission block 410.

[0042] The vibration plate 303, the motor and the electric push rod 511 are all electrically connected to the controller of the ball mill. The controller can control the start and stop of the vibration plate 303, the motor and the electric push rod 511, thereby improving the convenience of controlling the operation of the power device.

[0043] Working principle: The ball adding device is fixedly installed by fixing the support frame 2, and the grinding balls are added to the corresponding grinding ball classification storage bin 401 in sequence according to their sizes. For example, when small grinding balls need to be added, the small grinding balls are located at one end of the device close to the protective shell 517, and the electric push rod 511 controls the movement of the rotating shaft positioning frame 509. The rotating shaft positioning frame 509 drives the linkage rotating shaft 506 to move to the left toward the protective shell 517, so that the power transmission block 410 is engaged with the connecting clamp 408 on the left. The power transmission shaft 501 is controlled to rotate by the motor, and the power transmission shaft 501 drives the stirring rod 403 to rotate, so as to stir the grinding balls inside the grinding ball classification storage bin 401. At the same time, the transmission sprocket 502 and the chain can control the synchronous rotation of the transmission sprocket 503, and the transmission sprocket 503 drives the linkage member 504 to rotate, and the linkage block 508 and the sliding groove 507 are driven to rotate. The transmission causes the power transmission shaft 501 to drive the linkage rotating shaft 506 to rotate synchronously, and the linkage rotating shaft 506 drives the connecting snap ring 408 to rotate through the power transmission block 410, so that the linkage sleeve 406 drives the ball outlet wheel 404 to rotate. By controlling the number of rotations of the ball outlet wheel 404, the quantitative ball outlet bin 405 transports a quantitative amount of grinding balls from the grinding ball classification storage bin 401 to the inside of the grinding ball chute 301, and drives the grinding ball slide plate 302 to vibrate through the vibration plate 303, so that the vibration plate 303 better transports the grinding balls to the inside of the ball mill, thereby improving the convenience of adding balls to the ball mill. The linkage sleeve 406, which is far away from the power transmission block 410 and the connecting snap ring 408, is restricted by the double-sided damping ring 407 to avoid its linkage sleeve 406 from rotating. Through the above device, grinding balls of appropriate size can be quantitatively added to the ball mill according to demand, thereby improving the stability and convenience of adding balls.
