[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The application discloses a mining ball mill with safe production.

[0022] Reference Figure 1-3 The safe production mining ball mill includes a base 1, a ball mill drum 2, a steel ball module, a drive module 4 and a safety module 5; wherein the base 1 is a metal frame structure for providing a solid installation foundation, the two ends of the ball mill drum 2 are rotatably arranged at the two ends of the base 1 respectively, a plurality of steel ball modules are arranged, and a plurality of steel ball modules are freely arranged inside the ball mill drum 2 (not shown in the figure), the drive module 4 adopts a reduction motor form, the drive module 4 is fixedly arranged at one end of the base 1, and the drive module 4 and the ball mill drum 2 are connected in transmission so that the drive module 4 can be used to drive the ball mill drum 2 to rotate, the safety module 5 is fixedly arranged on the base 1, the safety module 5 and the drive module 4 are electrically connected, and the safety module 5 is used to control the drive module 4 to stop running when the operator enters the dangerous area, thereby improving the safety of the mining ball mill.

[0023] In the above, the specific structures and principles of the base 1, the ball mill drum 2, the ball mill drum 3, the steel ball module and the driving module 4 are all prior arts and will not be described in detail here.

[0024] In the above, the safety module 5 specifically includes a sensing mechanism 51, a control mechanism 52 and a detection mechanism 53; wherein the control mechanism 52 is fixedly arranged on the base 1, and the control mechanism 52 is used to control the start / stop of the driving module 4, and the control mechanism 52 specifically includes a PLC control unit 521, and the PLC control unit 521 adopts a single-chip microcomputer in the prior art as the main control chip, and the PLC control unit 521 is fixedly arranged on the base 1.

[0025] The sensing mechanism 51 is fixedly arranged on the base 1, and is used to sense the distance between the operator and the ball mill 2. The sensing mechanism 51 specifically includes an infrared transmitter 511 and an infrared receiver 512. The infrared transmitter 511 and the infrared receiver 512 are respectively fixedly arranged at two ends of the base 1. The infrared transmitter 511 and the infrared receiver 512 are aligned with each other, and the infrared receiver 512 and the PLC control unit 521 of the control mechanism 52 are electrically connected through a preset wire, so that the infrared receiver 512 can receive the infrared signal emitted by the infrared transmitter 511, and feed back the normal infrared transmission signal to the PLC control unit 521 of the control mechanism 52.

[0026] The detection mechanism 53 is fixedly arranged on the base 1, and is used to detect the detection performance of the sensing mechanism 51. The detection mechanism 53 specifically includes a linear motor 531 and a baffle 532. The linear motor 531 is fixedly arranged on the base 1, and the baffle 532 is fixedly arranged at the output end of the linear motor 531. The linear motor 531 can drive the baffle 532 to move between the infrared transmitter 511 and the infrared receiver 512 to cut off the infrared signal emitted by the infrared transmitter 511, so that the infrared receiver 512 feeds back the signal that the infrared is cut off to the PLC control unit 521 of the control mechanism 52.

[0027] When in use, the sensing mechanism 51 is turned on so that the infrared receiver 512 can receive the infrared signal emitted by the infrared transmitter 511, and the signal of normal infrared transmission is fed back to the PLC control unit 521 of the control mechanism 52. If the operator moves to a relatively close distance from the ball mill drum 2, that is, when the operator enters the dangerous area, the operator's body will block and cut off the infrared signal emitted by the infrared transmitter 511, so that the infrared receiver 512 feeds back the signal of the cut-off infrared to the PLC control unit 521 of the control mechanism 52, and the PLC control unit 521 immediately controls the driving module 4 to stop running, so that the ball mill drum 2 stops rotating, and the personal safety of the operator is avoided as much as possible, thereby improving the safety of the mining ball mill. Subsequently, the operator resets and starts the mining ball mill to continue to crush the ore material.

[0028] In addition, the PLC control unit 521 controls the linear motor 531 to run periodically, and the linear motor 531 periodically drives the baffle plate 532 to move between the infrared transmitter 511 and the infrared receiver 512, so that the baffle plate 532 cuts off the infrared signal emitted by the infrared transmitter 511, and the infrared receiver 512 feeds back the signal that the infrared is cut off to the PLC control unit 521 of the control mechanism 52. The PLC control unit 521 immediately determines whether the detection performance of the infrared transmitter 511 and the infrared receiver 512 is normal, thereby further improving the safety of the mining ball mill.
