Example Embodiment

[0018] The technical solution of this patent will be described in further detail below in conjunction with specific implementations:
[0019] See Figure 1-3 , An eccentric cone-shaped stone crushing device for mineral processing, comprising a bottom box 1, the upper right end of the bottom box 1 is vertically welded and fixedly installed with a column 14, the bottom box 1 has a hollow structure, and the bottom box 1 slides horizontally. The first return spring 9 is connected between the grinding basket 32 ​​and the inner wall of the right side of the bottom box 1. The bottom box 1 is horizontally slidably provided with a conical cover plate 20, and the bottom box 1 is located on the cone. A vertical plate 22 is vertically fixedly installed on the left side of the shaped cover plate 20, and a second return spring 10 is connected between the vertical plate 22 and the conical cover plate 20 and between the conical cover plate 20 and the column 14; the bottom box 1 is equipped with a bearing platform 2, the interior of the bearing platform 2 is a hollow structure, and the bearing platform 2 is equipped with a drive motor 25. The output shaft of the drive motor 25 is coaxially fixed with a driving shaft 6 which extends vertically downwards In the grinding basket 32, the lower end of the driving shaft 6 is provided with a cam 8, which abuts against the inner wall of the right side of the grinding basket 32; the driving shaft 6 is provided with a driving pulley 7, and the bearing platform 2 is provided with a driven The driven shaft 24 is provided with a driven pulley 3, and the driven pulley 3 and the driving pulley 7 are sleeved and connected with a transmission belt 5; the driven shaft 24 extends into the grinding basket 32, and the driven pulley The lower end of the shaft 24 is vertically slidably sleeved with a sliding sleeve 30, the bottom end of the sliding sleeve 30 is provided with a grinding plate 4, and the sliding sleeve 30 is provided with a shock-absorbing spring 31; The frustum 23, the lower surface of the crushing frustum 23 is provided with a universal roller 21 abutting the bearing platform 2, the upper end of the driven shaft 24 is eccentrically fixed on the lower bottom surface of the crushing frustum 23; the cone cover plate 20 slides on the side wall There is a threaded positioning post 19 which is located on the inner side of the conical cover plate 20. The threaded positioning post 19 is provided with a pressing plate 27. A number of limit springs 26 are arranged between the pressing plate 27 and the inner side wall of the conical cover plate 20. The threaded positioning post 19 is located on the outer part of the conical cover plate 20 and is provided with a threaded positioning sleeve 29 through a threaded connection sleeve; the left end of the column 14 is provided with a discharging port 17, and the discharging port 17 is provided with two crushing rollers 16, the discharging The lower end of the opening 17 is provided with a flexible bellows 18, the lower end of the flexible bellows 18 is connected with the conical cover plate 20, the side of the discharge port 17 is provided with a dust collecting net cover 15 connected with the discharge port 17, and the right side of the column 14 is provided with a collector The dust box 11 is provided with an exhaust fan 12 connected to the dust box 11, and a conveying pipe 13 is connected between the exhaust fan 12 and the dust collecting net cover 15; the surface of the pressure plate 27 and the surface of the crushing cone 23 are both provided A number of protrusions 28, and the inside of the grinding basket 32 ​​is communicated with the flexible bellows 18 through the channel formed by the carrying platform 2, the crushing cone 23 and the cone cover plate 20.
[0020] The working principle and use method of the present invention are:
[0021] When in use, the ore to be crushed is poured into the lower material port 17, and the crushing roller 16 performs preliminary crushing of the stone; then the ore enters between the crushing cone 23 and the pressing plate 27 through the flexible bellows 18, and the driving motor 25 passes through Drive the driving shaft 6 to realize the rotation of the driving pulley 7, the driving pulley 7 drives the driven pulley 3 to rotate through the transmission belt 5, the driven pulley 3 drives the driven shaft 24 connected to it to rotate, and the driven shaft 24 drives the crushing cone The table 23 rotates, and the eccentric rotation of the crushing cone 23 rotates and crushes the stone between the crushing cone 23 and the pressure plate 27. Because of the second return spring 10, the eccentrically rotating crushing cone 23 drives the cone cover The plate 20 moves back and forth slightly in the lateral direction to avoid damage to the device due to greater rigid impact, and at the same time has a good cushioning and shock absorption effect, greatly improving the stability, preventing the ore from jamming the crushing cone 23, and greatly reducing the failure rate , Improve work efficiency; rotate the threaded positioning sleeve 29 threaded with the threaded positioning column 19, so that the threaded positioning column 19 drives the pressure plate 27 to move closer to and away from the crushing cone 23, the distance between the pressure plate 27 and the crushing cone 23 can be based on The specific ore size is adjusted, and the adjustment is stronger, so that the ore can be fully crushed. At the same time, the driven shaft 24 drives the sliding sleeve 30 to rotate, and the sliding sleeve 30 drives the grinding plate 4 to rotate. The ore after the secondary crushing by the crushing cone 23 falls into the grinding basket 32 ​​and is subjected to the rotation of the grinding plate 4 For crushing, the damping spring 31 plays a buffering and damping effect during the crushing process of the grinding plate 4 on the ore, and improves the stability; the driving shaft 6 drives the cam 8 to rotate, and under the elastic action of the first return spring 9, the cam 8 drives The grinding basket 32 ​​is swayed from left to right, so that the ore at the bottom can be evenly spread, avoiding excessive concentration of ore, and improving the grinding and crushing effect of the grinding plate 4. This device has three crushing actions, and the ore crushing effect is very significant; start the ventilation In the machine 12, the dust generated from the discharge port 17 during the ore crushing process is collected by the dust collecting net cover 15, and is conveyed to the dust collecting box 11 through the conveying pipe 13, which has a good dust reduction and dust removal effect and avoids the spread of dust. Conducive to environmental protection.
[0022] In addition, it should be understood that although this specification is described in accordance with the implementation manners, not each implementation manner only includes an independent technical solution. This narration in the specification is only for clarity, and those skilled in the art should consider the specification as a whole The technical solutions in the embodiments can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
