Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a two-way complementary eccentric pressing plate extrusion crusher. Background Art

[0002] A crusher, also known as a stone crusher, is a crushing machine that can crush the mined raw ore into small particles through extrusion, bending and other methods during the processing of metal and non-metal ores. Product classification: jaw crusher, gyratory crusher, cone crusher, roll crusher, hammer crusher, impact crusher, etc. There are two types of jaw crushers in the prior art: simple pendulum jaw crusher and compound pendulum jaw crusher. The components directly contacting the material of these two crushers are both composed of a fixed pressing plate and a moving pressing plate. When the simple pendulum jaw crusher crushes the material, the crushing and extrusion stroke at the feeding port is very small, and the crushing stroke at the discharging port reaches the maximum. Therefore, although the crushing ratio is relatively larger than that of the compound pendulum jaw crusher, the crushing efficiency is low. When the compound pendulum jaw crusher crushes the material, the crushing and extrusion stroke at the feeding port can reach the maximum, but the crushing ratio is low. The closer to the discharging port, the smaller the crushing stroke, and finally it is almost impossible to crush the material. Although the crushing efficiency is better than that of the simple pendulum jaw crusher, the crushing ratio is low, which will increase the load of the subsequent crushing process and thus require more crushers to work. Content of the Utility Model

[0003] Aiming at the above-mentioned prior art, the utility model provides a two-way complementary eccentric pressing plate extrusion crusher, which mainly ensures that the two crushing and extrusion plates can always ensure that the crushing stroke reaches the maximum during the whole crushing process, and there is enough crushing stroke to fully extrude the material, so as to achieve a large crushing ratio, improve the efficiency and reduce the use cost.

[0024] Embodiment 1

[0025] Refer to the appendix Figures 1-5, this application provides a two-way complementary eccentric pressing plate extrusion crusher, which includes a frame 1, a first eccentric extrusion assembly 2 and a second eccentric extrusion assembly 3. Both the first eccentric extrusion assembly 2 and the second eccentric extrusion assembly 3 include an eccentric shaft 4, a movable jaw 5 and an adjustment assembly 6. The movable jaw 5 of the first eccentric extrusion assembly 2 and the movable jaw 5 of the second eccentric extrusion assembly 3 are rotationally symmetrically installed on the frame 1 to form complementary positions, constituting a "V"-shaped crushing cavity structure. The eccentric shaft 4 is rotatably sleeved on the frame 1. Further, the eccentric shaft 4 of the first eccentric extrusion assembly 2 is installed on the upper part of the frame 1, and the eccentric shaft 4 of the second eccentric extrusion assembly 3 is installed on the lower part of the frame 1. The middle part of the eccentric shaft 4 is movably sleeved with the movable jaw 5. A tooth plate 7 is provided on the front surface of the movable jaw 5, and the tooth plate 7 is used for crushing stones. The adjustment assembly 6 is provided inside the frame 1. The adjustment assembly 6 includes an adjustment base 8. A wedge-shaped adjustment block 9 and an elbow plate seat 10 are movably provided inside the adjustment base 8. One end of an elbow plate 11 is movably connected to the elbow plate seat 10, and the other end of the elbow plate 11 is movably connected to the movable jaw 5. The axial thickness of the wedge-shaped adjustment block 9 gradually changes, and the wedge-shaped adjustment block 9 can be axially moved by an external force. The moving direction of the wedge-shaped adjustment block 9 is perpendicular to the supporting direction of the elbow plate 11;When the wedge-shaped adjusting block 9 moves axially, the wedge-shaped adjusting block 9 forces the toggle seat 10 to move along the supporting direction of the toggle 11, which can be used to adjust the advance and retreat of the movable jaw 5 to realize the adjustment of the discharge opening size. The toggle 11 can transmit power, support the lower end of the movable jaw 5 to swing, and play a safety role. When difficult-to-break materials enter the crushing cavity, the toggle 11 breaks first, thereby protecting valuable parts of the machine (such as the movable jaw 5, etc.) from being damaged. One end of a support spring 12 is fixedly connected below the adjusting base 8, and the other end of the support spring 12 is fixedly connected to one end of a spring pull rod 121. The other end of the spring pull rod 121 is hinged to the movable jaw 5. The support spring 12 and the spring pull rod 121 are matched, and their main function is to fix the toggle 11, prevent the toggle 11 from falling off, and absorb and buffer the vibration and impact during the crushing process, having a good buffering and vibration reduction effect, which can effectively reduce the impact damage to the machine during the crushing process. Working principle: During operation, the eccentric shafts 4 of the first eccentric extrusion assembly 2 and the second eccentric extrusion assembly 3 rotate, causing the movable jaw 5 to approach and leave periodically. The toggle 11 supports the lower end of the movable jaw 5 to swing. At the same time, the spring pull rod 121 prevents the toggle 11 from falling off. The two movable jaws 5 form a "V"-shaped crushing cavity structure. Obviously, the two movable jaws 5 approach and leave each other periodically, thereby crushing the material in various ways such as extrusion and rubbing, causing the material to gradually fall from large to small until it is discharged from the discharge port. In this application, the first eccentric extrusion assembly 2 and the second eccentric extrusion assembly 3 with complementary positions cooperate with each other to crush the stones, increasing the crushing stroke. The whole process from the feed port to the discharge port is fully extruded, achieving a large crushing ratio while increasing the production capacity. The crushing ratio of the existing jaw crusher is 3 - 5, while the crushing ratio of this application can reach up to 15 at most, mainly ensuring that the crushing stroke reaches the maximum. Having enough crushing stroke can fully extrude the material, achieve a large crushing ratio and improve efficiency, thereby reducing asset investment, reducing energy consumption, reducing the consumption of consumables, and realizing energy conservation and emission reduction.;

[0026] Specifically, the frame 1 includes a connecting plate 13, a reinforcing rod 14 and a bearing vertical plate 15. Both ends of the connecting plate 13 are fixedly connected to the upper surface of the bearing vertical plate 15. Both ends of the reinforcing rod 14 are fixedly connected to the inner sides of the two bearing vertical plates 15.

The eccentric shaft 4 of the second eccentric extrusion assembly 3 is fixedly connected with a fourth belt pulley 20. The first belt pulley 17 is in transmission cooperation with the second belt pulley 18 through a first belt 201. The third belt pulley 19 and the fourth belt pulley 20 are in transmission cooperation through a second belt 202. During operation, the driving motor 16 drives the first belt pulley 17 to rotate. The first belt 201 drives the second belt pulley 18 to rotate, so as to realize the rotation of the eccentric shaft 4 of the first eccentric extrusion assembly 2, and further realize the periodic movement of the moving jaw 5 of the first eccentric extrusion assembly 2. Obviously, the third belt pulley 19 also rotates along with the second belt pulley 18. The third belt pulley 19 drives the fourth belt pulley 20 to rotate through the second belt 202, so as to realize the periodic movement of the moving jaw 5 of the second eccentric extrusion assembly 3 for crushing. The overall structure is powered by the driving motor 16, with a reasonable structure and energy saving.

[0028] Preferably, the jaw plate 7 is provided with a plurality of rows of teeth 21. Groove slots 22 are arranged between the rows of teeth 21.

[0031] Preferably, the eccentric shaft 4 of the second eccentric extrusion assembly 3 is fixedly provided with a flywheel 25. The flywheel 25 can store energy. Through its large moment of inertia, the flywheel 25 stores energy during the working stroke to overcome the resistance in other strokes, ensuring that the rotational angular velocity and output torque of the eccentric shaft 4 are as uniform as possible, thereby stabilizing the rotational speed of the driving motor 16.

[0032] Preferably, a guard plate 26 is arranged inside the frame 1. The guard plate 26 covers the moving jaw 5 and the eccentric shaft 4 along the axial direction of the eccentric shaft 4 to protect the moving jaw 5 and the eccentric shaft 4 from being impacted by crushed stones or foreign objects.

[0033] Preferably, the frame 1 is provided with a first bolt 27 which is threadedly connected to the frame 1. Obviously, by rotating the first bolt 27, the first bolt 27 can be advanced or retracted. The first bolt 27 is connected to the wedge-shaped adjusting block 9. The advancement or retraction of the first bolt 27 can drive the wedge-shaped adjusting block 9 to advance or retract. The advancement or retraction of the wedge-shaped adjusting block 9 can adjust the advancement or retraction of the movable jaw 5. By driving the wedge-shaped adjusting block 9 with the first bolt 27 to adjust the advancement or retraction of the movable jaw 5, the structure is simple and convenient for operation and maintenance.
