[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a ball mill that can be started and stopped by kicking and is easy to move.

[0035] Reference Figure 1 and Figure 2 A ball mill with foot-activated start / stop control and ease of movement comprises a frame 1, a first motor 2, a barrel 3, and a rotating base 4. The barrel 3 is rotatably connected to the rotating base 4 via bearings at both ends, enabling it to rotate on the rotating base 4, with the discharge port facing downward, facilitating the discharge of material from the barrel 3. The rotating base 4 is provided with a rotating shaft 41. A bearing block 11 is mounted on the top of the frame 1, through which the rotating shaft 41 passes, achieving a rotational connection with the frame 1. The first motor 2 is connected to the rotating base 4 to drive the barrel 3 to rotate about its axis. A photoelectric switch 5 is mounted at the bottom of the frame 1 and can be controlled by signaling through a foot-activated signal. The photoelectric switch 5 comprises a transmitter 51 and a receiver 52, mounted on the frame 1 and positioned opposite each other on the same horizontal plane. The receiver 52 is connected to a microcontroller 6 via wires, which in turn is connected to the first motor 2 via wires. This structure enables the microcontroller 6 to start and stop the first motor 2.

[0036] The first motor 2 drives the cylinder 3 to rotate by providing a driving wheel below the rotating base 4, which is connected to the cylinder 3 via a belt, and the first motor 2 drives the driving wheel to rotate via the pulley structure. Other structures can also be used to achieve the function of the first motor 2 driving the cylinder 3 to rotate.

[0037] The photoelectric switch 5 emits a beam of light at its transmitter 51, which is received at its receiver 52. If the operator blocks the light with their foot, the receiver 52 loses sight of the light. The microcontroller 6 detects the signal change and the decrease in light intensity at the receiver 52, and then starts or stops the first motor 2.

[0038] Specifically, the photoelectric switch 5 can be an infrared beam photoelectric switch 5, including an infrared emitter as a transmitting end 51 and a photodiode as a receiving end 52. The microcontroller 6 can be a single-chip microcomputer, which contains a program capable of identifying changes in the light signal received by the photodiode and controlling the operating state of the first motor 2 according to a preset logic.

[0039] In the structural design of the frame 1, in order to ensure stability and rigidity, the frame 1 can be welded into a frame structure using steel materials, while the rotating seat 4 and the rotating shaft 41 can be made of high-strength alloy steel to ensure the accuracy and durability of the transmission.

[0040] Reference Figure 2 In order to facilitate the rotation of the rotating seat 4 to discharge the material in the cylinder 3, the machine is further equipped with a rotating mechanism consisting of a second motor 12, a worm 13 and a worm wheel 14. The second motor 12 is fixed to the frame 1, and a worm 13 is fixed to its output shaft. The worm 13 is engaged with the worm wheel 14, and the worm wheel 14 is fixed concentrically with the rotating shaft 41. In this way, when the second motor 12 is started, it will drive the worm 13 to rotate, and the worm 13 drives the worm wheel 14, thereby causing the rotating seat 4 to rotate as a whole, thereby adjusting the inclination angle of the cylinder 3. In order to improve the stability of the worm 13, a frame is fixed on the frame 1, and the two ends of the worm 13 are rotatably connected to the frame.

[0041] The second motor 12 is also connected to the microcontroller 6 through a wire, so that the operator can control the second motor 12 through simple movements, thereby adjusting the angle of the ball mill, which greatly increases the flexibility and practicality of the equipment.

[0042] In terms of material selection, the worm 13 and the worm wheel 14 can be made of alloy steel with good wear resistance and hardened to increase their service life. The second motor 12 can be a stepper motor or a servo motor to provide precise control angle.

[0043] Reference Figure 2 and Figure 3 The bottom of the frame 1 is also equipped with a moving device 7, which consists of moving wheels 71, a fixed frame 72, and a locking device 73. The moving wheels 71 are located on both sides of the fixed frame 72 and are rotatably connected to the side walls of the fixed frame 72 via bearings, facilitating the movement of the device. The locking device 73, which includes a third motor 731, a pressure plate 732, and a screw 733, is used to lock the moving wheels 71 to prevent accidental movement of the device.

[0044] Reference Figure 3 Specifically, the pressure plate 732 is able to move vertically along the guide rails of the fixed frame 72. The third motor 731 is fixed to the fixed frame 72, and its output shaft is connected to one end of the lead screw 733, while the other end of the lead screw 733 is threadedly connected to the pressure plate 732. Thus, when the third motor 731 is started, it can drive the lead screw 733 to rotate, thereby driving the pressure plate 732 to move up and down, locking or releasing the moving wheel 71 as needed.

[0045] The moving wheel 71 can be made of a highly elastic rubber material to reduce the impact on the ground, reduce noise and improve the stability of the device. The fixing frame 72 and the pressing plate 732 can be made of a high-strength, lightweight aluminum alloy material.

[0046] The third motor 731 is also connected to the microcontroller 6 via a wire. The operator can also control the third motor 731 through simple actions to lock or unlock the moving wheel 71, thereby improving the operational convenience and safety of the device.

[0047] The microcontroller 6 processes the signal received by the photoelectric switch 5 and identifies different signal characteristics, such as signal sequence, frequency, amplitude, etc., thereby controlling different motors. In this application, different signal characteristics can be achieved by determining the number of kicks or the time the kick blocks the photoelectric switch 5. Other methods can also be used to distinguish the signal characteristics of the three motors.

[0048] The embodiment of the present application discloses a ball mill that can be started and stopped by a foot and is easily movable. The principle of operation is as follows: A photoelectric switch 5 is controlled by a foot to start and stop the cylinder 3, rotate the rotating base 4, and lock or unlock the moving wheel 71. This improves the convenience, flexibility, and safety of the equipment and enhances work efficiency. The equipment uses a microcontroller 6 to precisely control each motor, distinguishing control commands based on different signal characteristics, allowing the operator to easily control the entire equipment. Durability and stability are also taken into consideration in both material selection and structural design.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
