[0030] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a ball mill for grinding silicon micropowder, including a positioning plate 1, an outer wall of the positioning plate 1 is fixedly equipped with a first motor 4, an output shaft of the first motor 4 is fixedly equipped with a first outer cylinder 5, an outer wall of the first outer cylinder 5 is fixedly equipped with a limiting plate 11, a limiting wheel 3 is provided at the bottom of the positioning plate 1, an outer wall of the limiting wheel 3 is rollingly connected with a guide rail 2, an outer wall of the first outer cylinder 5 is tightly fitted with a second outer cylinder 6, one end of the second outer cylinder 6 is fixedly equipped with a turntable 9, and the other end of the second outer cylinder 6 is fixedly equipped with a second motor 7, an output shaft of the second motor 7 is fixedly sleeved with a transmission wheel 15, a transmission belt 8 is rollingly connected to the middle part of the transmission wheel 15, a screw rod 10 is fixedly installed on the outer wall of the transmission wheel 15, a slide groove 12 is provided on the outer wall of the second outer cylinder 6, the inner walls of the first outer cylinder 5 and the second outer cylinder 6 are both fixedly sleeved with a limiting shell 13, and a screen 14 is provided on the outer wall of the first outer cylinder 5. Through the provided positioning plate 1, guide rail 2, limiting wheel 3, first motor 4, first outer cylinder 5, and second outer cylinder 6 structure, after the user uses the ball mill to grind silicon micropowder, the second motor 7 can be used to drive the screw 10 to rotate, so that the first outer cylinder 5 moves away from the second outer cylinder 6, so that the user has enough space to maintain and clean the screen 14, ensuring that the screen 14 will not be blocked by residues, thereby improving the user's maintenance efficiency of the ball mill and the practicality of the ball mill.

[0031] like Figure 1 and Figure 3 As shown, a base is fixedly assembled at the bottom of the guide rail 2, and the bottom of the base is fixedly assembled to the ground, and the end of the turntable 9 away from the second outer cylinder 6 is rotatably connected to the outer wall of the base. Through the provided base and guide rail 2 structure, when the first outer cylinder 5 is moving, the guide rail 2 is used to limit the moving trajectory of the limiting wheel 3, thereby ensuring that the first outer cylinder 5 cannot be positionally shifted. At the same time, the first outer cylinder 5 can also be supported to prevent the first outer cylinder 5 from exerting excessive pressure on the screw rod 10 and the limiting plate 11 due to excessive weight, thereby improving the stability of the first outer cylinder 5 during movement and ensuring the user's subsequent use of the ductile iron machine.

[0032] like Figure 2 and Figure 5 As shown, a discharge trough is provided on the outer wall of the first outer cylinder 5, and the outer wall of the screen 14 is fixedly assembled with the inner wall of the discharge trough, and steel balls are placed on the inner walls of the first outer cylinder 5 and the second outer cylinder 6. Through the provided screen 14 and the discharge trough structure, when the user grinds the silicon micropowder through the ball mill, the screen 14 can screen the silicon micropowder, thereby eliminating the need for the user to screen the silicon micropowder after grinding, thereby improving the user's production efficiency of qualified silicon micropowder, and the steel balls can rub against the silicon micropowder when the first outer cylinder 5 and the second outer cylinder 6 rotate, thereby achieving the grinding effect.

[0033] like Figure 4 and Figure 5 As shown, a threaded hole is provided on the outer wall of the limit plate 11, and the inner wall of the threaded hole is threadedly connected to the outer wall of the screw rod 10. Through the structure of the threaded hole, the screw rod 10 and the limit plate 11, the user can rotate the screw rod 10 by operating the second motor 7, and during the rotation of the screw rod 10, the limit plate 11 is used to limit the first outer cylinder 5, so that the first outer cylinder 5 can only move horizontally and a distance is generated between the first outer cylinder 5 and the second outer cylinder 6, thereby facilitating the user to maintain and clean the screen 14, thereby improving the user's maintenance efficiency of the ball mill.

[0034] like Figure 4 and Figure 5 As shown, the inner wall of the slide groove 12 is slidably connected to the outer wall of the screw rod 10, there are two limit plates 11, and the two limit plates 11 are evenly distributed along the outer wall of the first outer cylinder 5. By setting the two limit plates 11 and the screw rod 10 structure, the two limit plates 11 are used to push the first outer cylinder 5, so that the limit wheel 3 can move linearly along the guide rail 2, so as to facilitate the user to open the ball mill to perform maintenance operations on the screen 14, thereby improving the automation and practicality of the equipment.

[0035] like Figure 1 and Figure 3 As shown, a feed pipe penetrates the outer wall of the first outer cylinder 5 until it reaches the inner wall of the first outer cylinder 5, and the outer wall of the first outer cylinder 5 is rotatably connected to the outer wall of the positioning plate 1. Through the provided feed pipe and positioning plate 1 structure, during the grinding process, the user can drive the first outer cylinder 5 to rotate through the first motor 4, and the limit plate 11 and the screw 10 can allow the second outer cylinder 6 to rotate synchronously with the first outer cylinder 5, so as to achieve the effect of automatic grinding of silicon micropowder. The positioning plate 1 can cooperate with the turntable 9 to limit the first outer cylinder 5 and the second outer cylinder 6 to ensure the stability of the first outer cylinder 5 and the second outer cylinder 6 during rotation. The feed pipe can facilitate the user to put silicon micropowder into the equipment.

[0036] The technical solution provided by the utility model is to feed silicon micropowder into the first outer cylinder 5 and the second outer cylinder 6 through a feeding pipe. At this time, the user can drive the first outer cylinder 5 and the second outer cylinder 6 to rotate synchronously through the first motor 4, so as to generate friction between the steel balls and the silicon micropowder to achieve the grinding effect. The two limiting shells 13 can ensure that the silicon micropowder can only accumulate in the middle of the first outer cylinder 5 and the second outer cylinder 6, thereby increasing the grinding effect of the steel balls on the silicon micropowder. At this time, qualified silicon micropowder will fall to the outside of the equipment through the screen 14 and the discharge trough, and the user will collect it. After the operation is completed, the operation of the second motor 7 increases the distance between the first outer cylinder 5 and the second outer cylinder 6, thereby facilitating the user to clean the residue on the screen 14, thereby improving the user's maintenance efficiency inside the equipment.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.
