[0001] This utility model relates to the field of crushing equipment technology, specifically a cone crusher motor cone balancing device. Background Technology

[0002] A cone crusher is a type of crushing machinery suitable for raw materials in the metallurgical, construction, road building, chemical, and silicate industries. Depending on the crushing principle and the desired particle size, it is available in many models. Crushers are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. Cone crushers offer a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size, making them suitable for medium and fine crushing of various ores and rocks.

[0003] Its main working principle is to drive an internal moving cone to perform eccentric circular motion through an external power device, thereby changing the distance between the outer surface of the moving cone and the inside of the cavity, thus achieving the crushing and extrusion of ore and other materials, and fulfilling its main function. During the extrusion process of the moving cone, vibration and unbalanced motion are prone to occur, which can affect the operation of the equipment.

[0004] In actual production applications, a self-made wear-resistant material feeding device with an early-hat type is added to the top of the moving cone. The top is the main point of impact. After the material is added to the receiving box, the wear rate of the top and upper middle part is reduced and the overall service life is extended. However, this will also increase the occurrence of unbalanced movement of the device.

[0005] Therefore, it is necessary to design a cone balancing device for a cone crusher. Utility Model Content

One end of the hydraulic cylinder is hinged to the hinge seat, and the other end of the hydraulic cylinder is hinged to the inner wall of the moving cone. A bottom cover is interference-fitted into the bottom of the ring disc, and a top cover is screwed onto the top of the ring disc. The disc body has an internal oil passage that runs through the inner and outer walls. An external connecting pipe is fitted into the outer port of the internal oil passage, and the external connecting pipe is connected to the hydraulic cylinder via a connecting pipe.

[0011] According to the above technical solution, the number of hydraulic cylinders is the same as the number of internal oil circuits, and they are matched one by one.

[0012] According to the above technical solution, the ring body of the ring disk has circumferentially distributed flange bolt holes, which are arranged alternately with the internal oil passages.

[0013] According to the above technical solution, the wide end of the adjusting core cylinder is provided with an internal hexagonal groove.

[0014] According to the above technical solution, the inner diameter of the wide opening of the adjusting core cylinder is 1.5 to 1.7 times the inner diameter of the small opening, and the inner diameter of the small opening of the adjusting core cylinder is 2 to 2.5 times the maximum diameter of the flow-limiting cone.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model provides a technical solution: a cone crusher moving cone balancing device, including a ring disc 1 and a hydraulic cylinder 2. The ring disc 1 has a hinge seat 8 integrally formed around its perimeter. One end of the hydraulic cylinder 2 is hinged to the hinge seat 8, and the other end of the hydraulic cylinder 2 is hinged to the inner wall of the moving cone. The bottom opening of the ring disc 1 is interference-fitted with a bottom cover 4, and the top opening of the ring disc 1 is screwed with a top cover 3. The disc body of the ring disc 1 has an inner oil passage 5 that runs through the inner and outer walls. The outer port of the inner oil passage 5 is fitted with an outer pipe 7, and the outer pipe 7 is connected to the hydraulic cylinder 2 through a connecting pipe 9 for external oil passage communication.

[0028] The internal cavity is formed by the ring plate 1, bottom cover 4 and top cover 3. The internal cavity structure is coaxially combined with the mounting body of the moving cone. The internal oil circuit 5 connects the internal cavity and the connecting pipe 9. The connecting pipe 9 is connected to the hydraulic cylinder 2 through the external pipe 7. The hydraulic cylinder 2 achieves damping flow of hydraulic oil in the complete oil circuit. At the same time, the hydraulic cylinder 2 achieves shock absorption and unbalanced motion damping limitation of the moving cone through the hinge with the inside of the moving cone.

[0029] Specifically, the top cover 3 includes a top plate 301, the lower surface of the top plate 301 is integrally formed with a threaded insert 302, and the outer periphery of the upper surface of the top plate 301 is provided with circumferentially distributed engagement holes 303. The top plate 301 and the threaded insert 302 are coaxial.

[0030] The top plate 301 and the threaded insert 302 form the main structure of the top cover 3. The threaded insert achieves a sealed combination with the upper opening of the ring plate 1. The engagement hole 303 allows the external device to effectively engage the top plate 301, enabling the disassembly and installation of the entire top cover 3.

[0031] Specifically, the inner port of the inner oil circuit 5 is screwed with a flow control valve 6. The flow control valve 6 includes a valve cylinder 601. An adjusting core cylinder 602 is screwed inside the valve cylinder 601. A flow limiting cone 603 is integrally formed at the bottom of the valve cylinder 601. The flow limiting cone 603 and the small end of the adjusting core cylinder 602 cooperate with each other.

[0032] The internal oil circuit 5 controls the flow of hydraulic oil through the flow control valve 6, and further restricts the flow of hydraulic oil returning from the hydraulic cylinder 2 to the internal cavity. The valve cylinder 601 is the external structure of the flow control valve 6, which provides a forming base for the flow limiting cone 603 and a mounting base for the adjusting core cylinder 602. The small opening of the adjusting core cylinder 602 cooperates with the flow limiting cone 603 to achieve overall flow control adjustment.

[0033] Specifically, the number of hydraulic cylinders 2 is the same as the number of internal oil circuits 5, and they are matched one by one.

[0034] By matching and installing one-to-one, better independent connection control can be achieved, avoiding mutual interference.

[0035] Specifically, the ring disc 1 has circumferentially distributed flange bolt holes 10 vertically arranged on its ring body, and the flange bolt holes 10 and the internal oil passage 5 are arranged alternately.

[0036] The flange bolt holes 10 facilitate the effective combination of the ring disc 1 and the moving cone mounting body, and ensure the stability of the installation.

[0037] Specifically, the wide end of the adjusting core cylinder 602 is provided with an internal hexagonal groove.

[0038] The internal hexagonal recess facilitates the installation, disassembly, and adjustment of the adjusting core 602.

[0039] Specifically, the inner diameter of the wide opening of the adjusting core 602 is 1.5 to 1.7 times the inner diameter of the small opening, and the inner diameter of the small opening of the adjusting core 602 is 2 to 2.5 times the maximum diameter of the flow-limiting cone 603.

[0040] By adjusting the difference in the inner diameter between the wide and narrow openings of the core cylinder 602, the flow rate of the outward-flowing hydraulic oil is kept stable, and the flow of the returning hydraulic oil is restricted. The difference in the inner diameter between the narrow opening of the core cylinder 602 and the maximum diameter of the flow-limiting cone 603 allows for a wide range of flow-limiting adjustment.

[0041] Working principle: When in use, after the entire device is connected and installed, when the moving cone is driven, the hydraulic oil flows to the hydraulic cylinder 2 in the corresponding direction. At the same time, the hydraulic oil in the opposite hydraulic cylinder 2 flows back into the internal cavity. Under the control of the flow control valve 6, the overall hydraulic oil resistance flow is realized, thereby realizing the vibration and unbalanced motion control of the moving cone, and then realizing the required balance control of the moving cone.
