[0019] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.
[0020] Embodiment 1, the technical solution is that when the utility model is in use, the adjusting rod 26 is provided with a screw 9 that is threadedly connected to the connecting rod 4. The adjusting rod 26 can be rotated to drive the connecting rod 4 through the screw 9, so that the connecting rod 4 together with the mounting frame 6 can move vertically along the vertical rod 18, and then the conical grinding roller 11 fixedly connected to the vertical shaft 7 can move vertically, and then the gap between the inner wall of the conical shell 2 and the outer edge of the conical grinding roller 11 can be adjusted, and then the particle size of the ground material can be changed, so that the device can meet the grinding requirements of different particle sizes, reduce the setting of grinding devices of different specifications, and save workshop space and production costs. The present application can grind the material through the arrangement of the conical shell 2 and the conical grinding roller 11, and the inner wall of the conical shell 2 and the outer wall of the conical grinding roller 11 are evenly distributed with a number of grinding particles 25, which can ensure sufficient grinding, and the ground material can be discharged from the discharging device 17. The present application has a simple structure, is easy to use, and has strong practicality.
[0021] Embodiment 2, based on embodiment 1, specifically, when the present application is in use, the motor 8 is started, and the material can be put in from the feed hopper 3. The motor 8 starts to drive the vertical shaft 7 to rotate, and then the conical grinding roller 11 will also rotate accordingly. The distance between the outer edge of the conical grinding roller 11 and the inner wall of the conical shell 2 gradually narrows from top to bottom, so that the conical grinding roller 11 can grind the input material during the rotation process. Furthermore, the inner wall of the conical shell 2 and the outer wall of the conical grinding roller 11 are evenly distributed with a number of grinding grains 25, which can ensure sufficient grinding. During the rotation of the conical grinding roller 11, the short shaft 10 plugged into the bottom connecting hole 12 of the conical grinding roller 11 also rotates accordingly, and the scraper 22 on the short shaft 10 also rotates synchronously, and pushes the ground material to the discharge hole 21, so that the material is discharged from the discharge hole 21.
[0022] Embodiment 3, on the basis of embodiment 2, when it is necessary to change the particle size of the ground material, it can be adjusted by the adjusting rod 26 above the frame 5. Specifically, the adjusting rod 26 on the crossbar 19 is rotated clockwise. In order to facilitate the rotation of the adjusting rod 26, a rotating wheel 23 is provided. The screw rod 9 will drive the connecting rod 4 as the adjusting rod 26 rotates clockwise. The connecting rod 4 is restricted by the limit ring 20 and the vertical rod 18. Therefore, the connecting rod 4 moves downward along the vertical rod 18 when the screw rod 9 rotates clockwise, and then the mounting frame 6 connected to the vertical shaft 7 and the conical grinding roller 11 and other related parts will also move downward synchronously, thereby changing the relative distance between the outer edge of the conical grinding roller 11 and the inner wall of the conical shell 2, and then the grinding particles of the material can be changed by 25 degrees. Correspondingly, turning the adjusting rod 26 counterclockwise can finally drive the conical grinding roller 11 and other related parts to move upward, thereby also changing the relative distance between the outer edge of the conical grinding roller 11 and the inner wall of the conical shell 2, and then the grinding particles of the material can also be changed by 25 degrees.
[0023] Embodiment 4, on the basis of embodiment 2, a short shaft 10 plugged into the bottom connection hole 12 of the conical grinding roller 11 is rotatably connected to the support plate 1, a baffle 15 is arranged on the short shaft 10, and a support spring 16 is arranged at the opposite end of the baffle 15 and the conical grinding roller 11, and the short shaft 10 and the support spring 16 jointly provide support for the bottom of the conical grinding roller 11 to ensure the stability of the conical grinding roller 11 during operation. A guide block 14 corresponding to the vertical groove 13 is arranged on the short shaft 10, which limits the short shaft 10 to rotate synchronously with the conical roller, and can also ensure that the conical grinding roller 11 and the short shaft 10 can move vertically, so as to facilitate the adjustment of the position of the conical grinding roller 11 by the adjustment rod 26, thereby changing the particle size of the grinding material. The support legs 24 provided can provide support for this application.
