Description

Technical Field

[0001] This utility model relates to the field of construction engineering, and in particular to a stone crusher for construction engineering. Background Technology

[0002] This utility model relates to crushing equipment for crushing materials such as rocks, building materials, and various ores. The Chinese patent authorization announcement number is CN 214811151 U, and the invention title is "Cone Sand Making Machine." This utility model provides a cone sand making machine, including a machine body shell, a drive pulley, an eccentric sleeve, an inner swing sleeve, a hydraulic cylinder column, and an inner cone. The drive pulley drives the eccentric sleeve, which in turn drives the inner swing sleeve to perform synchronous eccentric swinging. A wear-resistant upper cover is fixed to the inner swing sleeve, and the end faces of the eccentric sleeve and the inner swing sleeve form an angle A with the horizontal plane. The wear-resistant inner cone is fixed to the inner cone by an inner cone wear-resistant fixing nut. The wear-resistant upper cover and the wear-resistant inner cone extend downwards simultaneously to form a relatively sealed sleeve cavity, with a feed inlet at the upper part of the sealed sleeve cavity. The outlet of the sealed sleeve cavity is connected to the inlet of the cone sand making machine cavity, which is formed by the wear-resistant wall component and the bottom of the inner cone. Its large and small gears have a complex structure and are difficult to maintain, making it difficult to crush large quantities; at the same time, under the same cavity, it is difficult to improve its speed and output through design. Summary of the Invention

[0003] This utility model provides a simple and easy-to-maintain dual-shaft cone crusher.

[0004] The technical solution of this utility model is: a double vertical shaft cone crusher, including a cone crusher and two synchronous eccentric shafts on the left and right. The synchronous eccentric shafts are driven by a motor to perform synchronous eccentric displacement rotational motion; the cone on the crusher body is driven by the two synchronous eccentric shafts to perform synchronous eccentric displacement rotational motion.

[0005] Furthermore, the aforementioned synchronous eccentric shaft comprises a drive pulley, an upper bearing, an upper bearing bracket, an upper eccentric bearing, an eccentric shaft, an eccentric bracket, a lower eccentric bearing, a lower bearing bracket, a lower bearing, and a frame support. The drive pulley synchronously drives the eccentric shaft to move under the motor's influence. The upper and lower bearings jointly support the eccentric shaft, and the upper and lower bearing brackets respectively house the upper and lower bearings. The eccentric shaft thus drives the upper and lower eccentric bearings to rotate and displace the eccentric bracket's structural components. The left and right eccentric brackets drive the upper cone to rotate and displace synchronously.

[0006] Furthermore, the aforementioned cone crusher includes a lower cone sleeve, an upper cone, a lower cone body, an adjusting inner cylinder, an adjusting outer cylinder, and a feed inlet; a space is formed between the lower cone sleeve and the upper cone body, the upper cone body is provided with a feed inlet, and the lower cone body is provided with a discharge outlet at the bottom of the cavity; the adjusting inner cylinder body is placed inside the adjusting outer cylinder body, the lower cone body is installed on the adjusting inner cylinder body, and the lower cone sleeve is installed on the lower cone body.

[0007] Furthermore, the size of the discharge port of the aforementioned cavity can be adjusted by freely raising and lowering the inner and outer cylinder assembly of the inner and outer cylinders.

[0008] The beneficial effects of this utility model are as follows: The structure of the upper cone rotating synchronously under the drive of two synchronous eccentric shafts is simple, which makes it easy to increase the speed of the upper cone and increase the production capacity within the same cavity; the cavity can also be adjusted by adjusting the size of the inner cylinder 14, the outer cylinder 15, and the inner and outer cylinder assembly to freely rise and fall, thereby adjusting the production capacity and thickness.

Detailed Implementation

[0015] See Figure 1-3Drive pulley A1 and drive pulley B1 rotate synchronously under the synchronous drive of the motor. Upper bearing A2, upper bearing B2, lower bearing A9, and lower bearing B9 support eccentric shaft A5 and eccentric shaft B5 respectively. Thus, upper bearing A4, upper eccentric bearing B4, lower bearing A9, and lower bearing B9 synchronously drive the eccentric bracket A6 and eccentric bracket B6 to rotate synchronously.

[0016] Eccentric support A6 and eccentric support B6 synchronously drive the upper cone 20 of the cone crusher to rotate.

[0017] The cone crusher consists of a base 11, a lower cone sleeve 12, a lower cone body 13, an adjusting inner cylinder 14, an adjusting outer cylinder 15, a hydraulic cylinder 19, and an upper cone body 20.

[0018] See Figure 4 Driven by the motor, the pulley A1 rotates synchronously with an eccentric displacement, which in turn drives the upper eccentric bearing A4 and the lower bearing A9 to rotate and displace the eccentric bracket A6.

[0019] The cavity of this utility model can also be freely raised and lowered by adjusting the inner cylinder 14 and the outer cylinder 15, which are part of the inner and outer cylinder assembly.

[0020] The hydraulic cylinder 19 adjusts the size of the A-feed inlet 17 and the B-feed inlet 18, thereby regulating the production capacity and the fineness of the material. The angle between the two inlets 17 and 18 is adjusted, gradually increasing and decreasing to generate crushing energy. The feed inlet 16 rotates with the eccentric displacement, automatically distributing the feed and ensuring the larger angle inlet is full, preparing for the next crushing cycle. This creates a continuous circular displacement motion, significantly increasing the crushing capacity.

[0021] See Figure 5 The diagram shows a partial enlarged view of a cone crusher. The upper cone 20 and lower cone 12 form a cavity. The feed inlet 16 is used to feed stone. Feed inlets 17 (A) and 18 (B) are located on either side of the left and right synchronous eccentric shafts, respectively, forming the discharge outlets of a continuous cavity. When the upper cone 20 rotates eccentrically, the cavities on its left and right sides change shape. Simultaneously, the descending stone is crushed due to the pressure exerted by the cavity changes. The adjusting inner cylinder 14 is placed inside the adjusting outer cylinder 15. The lower cone 132 is mounted on the adjusting inner cylinder 14, and the lower cone sleeve 12 is mounted on the lower cone 13.
