DETAILED DESCRIPTION

[0011] See also Figure 1-3, the driving belt pulley A1 and the driving belt pulley B1 perform synchronous eccentric displacement rotation motion under the synchronous drive of the motor, the upper bearing A2, the upper bearing B2 and the lower bearing A9, the lower bearing B9 respectively support the eccentric shaft A5 and the eccentric shaft B5, so that the upper bearing A4, the upper eccentric bearing B4, the lower bearing A9, the lower bearing B9 respectively synchronously drive the eccentric bracket A6 and the eccentric bracket B6 of the same body structure to perform displacement rotation motion.

[0012] The eccentric bracket 1 A6 and the eccentric bracket 2 B6 synchronously drive the upper cone 20 of the cone crusher to rotate.

[0013] The cone crusher is composed of a base 11, a lower cone sleeve 12, a lower cone body 13, an adjustable inner cylinder body 14, an adjustable outer cylinder body 15, a cylinder 19 and an upper cone body 20.

[0014] See also Figure 4 : The driving belt pulley A1 performs synchronous eccentric displacement rotation motion under the synchronous drive of the motor, thereby the upper eccentric bearing A4 and the lower bearing A9 drive the same body structure of the eccentric bracket A6 to perform displacement rotation motion.

[0015] The cavity of the present invention can also be adjusted by adjusting the inner cylinder body 14 and the outer cylinder body 15 to freely rise and fall, and the oil cylinder 19 can adjust the size of the A material opening 17 and the B material opening 18 to adjust the production capacity and thickness. The two angles of the A material opening 17 and the B material opening 18 are changed from small to large and from large to small to generate crushing energy. The feed opening 16 will automatically distribute the feed with the eccentric displacement rotation movement, so that the large angle port is filled with material to prepare for the next crushing cycle. A circular displacement movement is formed over and over again, thereby greatly increasing the crushing capacity.

[0016] See also Figure 5 , a partial enlarged view of the cone crusher, a cavity is formed between the upper cone 20 and the lower cone 12, the feed port 16 is used to feed stones, the A feed port 17 and the B feed port 18 are located on the left and right synchronous eccentric shafts, respectively, and they are the discharge ports of a continuous cavity. When the upper cone 20 performs eccentric displacement and rotation, the cavities on its left and right sides change, and the descending stones are crushed due to the pressure caused by the change in the cavity.

[0017] The adjusting inner cylinder body 14 is placed in the adjusting outer cylinder body 15 , the lower cone body 132 is installed on the adjusting inner cylinder body 14 , and the lower cone sleeve 12 is installed on the lower cone body 13 .
