[0002] With the rapid development of the construction industry, the variety of aggregates of different specifications has increased. Cone crushers, as one of the most important pieces of equipment, are also currently popular crushing machines. They are commonly used in the crushing and processing of various ores. Due to their high output, good stability, and long service life, cone crushers are widely used in the market. In daily operation, one of the important factors affecting the output of a cone crusher is the size of the discharge opening. Operators must be proficient in adjusting the size of the discharge opening to ensure smooth production and that the particle size of the finished aggregate meets the requirements. In existing multi-cylinder hydraulic cone crushers, the size of the discharge opening is adjusted by an observer who observes the size of the aggregate particles near the discharge opening to determine the opening size, and then manually adjusts the discharge opening size. Under this method, changes in aggregate size are only visible to the naked eye when the liner wears significantly. This observation of aggregate changes at this point has a large lag, and this method requires manual intervention, resulting in low efficiency. Utility Model Content

[0003] To address the aforementioned problems, this invention provides an intelligent adjustment device for the discharge opening of a multi-cylinder hydraulic cone crusher that can quickly and intelligently adjust the size of the discharge opening. This device allows for rapid adjustment of the discharge opening even when the machine is not stopped, saving labor costs and improving production efficiency.

Detailed Implementation

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0017] Example 1

[0018] like Figure 1 and 2 As shown, an intelligent adjustment device for the discharge port of a multi-cylinder hydraulic cone crusher includes a multi-cylinder hydraulic cone crusher. The multi-cylinder hydraulic cone crusher includes a lower frame 13, within which a crushing wall assembly 8 is disposed. A mortar wall assembly 14 is disposed above the crushing wall assembly 8. A discharge port A is formed between the fixed cone liner of the mortar wall assembly 14 and the moving cone liner of the crushing wall assembly. The mortar wall assembly 14 includes a connecting outer wall, with a first thread 15 on the outer circumference of the connecting outer wall. A drive ring 16 is fitted above the mortar wall assembly 14, the drive ring 16 including an inner ring surface and an outer ring surface. The inner annular surface includes a longitudinally arranged second thread 17, which mates with the first thread 15. The outer annular surface is provided with a large gear ring 9, which vertically meshes with a pinion 10. The pinion 10 is connected to a hydraulic motor 11. The system also includes an intelligent control system, which includes a PLC control cabinet. The PLC control cabinet drives a controller connected to the hydraulic motor 11. The system also includes a signal acquisition system, which includes a proximity switch 1. The proximity switch 1 acquires the rotation of the pinion 10 and transmits the data signal to the PLC control cabinet via a signal line.

[0019] The working principle of this embodiment is as follows: When the hydraulic motor 11 is working, the small gear 10 of the hydraulic motor rotates, driving the large gear ring 9 to rotate. Then, the mortis wall assembly 14 moves up and down due to the threaded connection with the support sleeve 2, thereby changing the discharge port A. The number of gear teeth rotated and the pitch movement data of the support sleeve 2, which are counted by the gear sensor proximity switch 1, are transmitted to the PLC control cabinet through the signal line. The computer program automatically calculates the size of the discharge port A and displays it on the central control screen of the PLC control cabinet. When it is necessary to adjust the size of the discharge port A, the PLC control cabinet controls the hydraulic motor to adjust the forward and reverse rotation of the small gear, thereby adjusting the forward and reverse rotation of the large gear ring, and thus adjusting the size of the discharge port A.

[0020] In other specific embodiments, the lower part of the first thread 15 is connected to a support sleeve 2. The support sleeve 2 includes at least an inner sleeve surface, on which a third thread 18 is provided. The third thread 18 mates with the first thread 15. The support sleeve 2 is connected to the lower frame 13, and a plurality of release cylinders 12 are arranged circumferentially between the support sleeve 2 and the lower frame 13. The support sleeve 2 is connected to a locking ring 6, which includes at least a second inner ring surface. The second inner ring surface is provided with a fourth thread 19, which mates with the outer ring of the first thread 15. A locking hole is provided between the locking ring 6 and the support sleeve 2. A positioning sleeve 4 is provided in the locking hole, and the locking ring 6 and the support sleeve 2 are connected by bolts 3 and washers 5. A cylinder groove is provided between the locking ring 6 and the support sleeve 2, and a locking cylinder 7 is provided in the cylinder groove.

[0021] The support sleeve 2 is connected to the lower frame 13 via the release cylinder 12. The locking ring 6 and the support sleeve 2 are connected to the gasket 5 via the positioning sleeve 4, bolt 3, and bolt 3. The locking ring 6 can move up and down via the positioning sleeve 4. The bolt 3 connects the positioning sleeve 4 and the support sleeve 2 and limits the movement of the locking ring 6. The locking cylinder 7 is installed in the cylinder groove between the locking ring 6 and the support sleeve 2. When the locking cylinder 7 is not pressing, the locking ring 6 is pressed onto the support sleeve 2 by gravity. When the locking cylinder 7 presses, it lifts the locking ring 6. The acetabular wall assembly 14 is connected to the support sleeve 2 via the first thread. The first thread of the acetabular wall assembly 14 also engages with the second thread of the drive ring and the third and fourth threads of the support sleeve 2 and the locking ring 6. When the locking ring 6 is lifted by the locking cylinder 7, the acetabular wall assembly 14 is tightened by the threads. When the locking cylinder depressurizes, it can loosen the acetabular wall assembly 14.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.
