Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cone crushers, specifically to a novel multi-cylinder cone crusher. Background Technology
[0002] Cone crushers are raw material processing equipment widely used in industries such as metallurgy, construction, and road building. Their large crushing ratio, high efficiency, low energy consumption, and uniform product particle size make them particularly suitable for crushing various ores and rocks. Existing cone crushers can basically meet daily usage needs, but there are still some shortcomings that require improvement.
[0003] In existing technologies, safety cylinders serve as a buffer for safety. However, these safety cylinders are connected in series. When the material is hard or accidentally jams, the multi-cylinder cone crusher will trigger the over-iron protection. This means that, driven by a hydraulic structure outside the crusher, the upper body is actively moved upwards to widen the gap between the moving cone assembly and the fixed cone assembly, allowing the jammed material to fall back down. Because the safety cylinders in existing technologies are connected in series, their synchronization cannot be guaranteed. Tests have shown that safety cylinders closer to the oil tank activate first, while those farther away activate later, resulting in an imbalance in the lifting of the upper frame.
[0004] A patent publication number (CN118045654B) was found, entitled "A Multi-Cylinder Hydraulic Cone Crusher," which specifically discloses a multi-cylinder hydraulic cone crusher, including a lower body and an upper body. A moving cone assembly is housed within the lower body, and a fixed cone assembly is housed within the upper body. A hydraulic unit is located outside the lower body, with its output end connected to the upper body. The crusher also includes a diversion port located at the lower end of the lower body, with a first discharge branch at its lower end. The upper and lower machine bodies are connected by a first discharge port and a second discharge port; a flap that is rotatably mounted inside the diversion port; and a linkage assembly that links the upper machine body and the flap. When the upper machine body moves down and comes into close contact with the lower machine body, the flap rotates to make the diversion port only connect with the first discharge port. When the upper machine body moves up and moves away from the lower machine body, the flap rotates to make the diversion port only connect with the second discharge port. The linkage assembly includes a connecting rod that moves up and down synchronously with the upper machine body. A rack is fixedly mounted on the lower end of the connecting rod. The rotating shaft of the flap is coaxially connected to a gear that meshes with the rack.
[0005] Analysis of the publicly available materials reveals that the synchronous lifting and lowering of the upper body is achieved by setting up components such as connecting rods, racks, flaps, and rotating shafts. The structure is relatively complex and employs a lot of mechanical transmission. Even using mechanical methods, it is still impossible to maintain a synchronous state. Utility Model Content
[0006] In view of this, the present invention provides a novel multi-cylinder cone crusher that not only enables synchronous lifting of the upper frame, but also has a simple structure and stable operation.
[0007] To address the aforementioned technical problems, this utility model provides a novel multi-cylinder cone crusher, including a base, a lower frame mounted on the base, and an upper frame mounted above the lower frame.
[0008] A support plate, wherein the support plate is disposed on the outside of the upper frame;
[0009] A synchronous hydraulic system includes a safety cylinder connected to an upper frame and a base. The safety cylinder is connected to an oil outlet pipe, which is connected to a throttle valve. The throttle valve is equipped with a flow divider pipe, which is connected to a supply pipe. The safety cylinders are connected in parallel.
[0010] Furthermore, the throttle valve is fixed on the base, the throttle valve is connected to an oil inlet pipe, and the safety cylinder is connected to the safety cylinder through the oil inlet pipe. The safety cylinder is connected to an oil outlet pipe, and the throttle valve is connected to the oil outlet pipe.
[0011] Furthermore, the number of throttle valves is several, and the throttle valves are connected in parallel through the oil supply pipe, with one throttle valve controlling two lifting nodes.
[0012] Furthermore, the throttle valve is connected to an accumulator for driving the throttle valve.
[0013] Furthermore, the oil supply pipe is located on the outer side of the lower frame.
[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0015] 1. By setting a throttle valve, the oil inlet speed into the safety cylinder can be controlled, thereby solving the synchronization problem of safety cylinders at different distances from the oil tank and achieving timely synchronization of the safety cylinders.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0022] like Figure 1-3 As shown: Example
[0023] A novel multi-cylinder cone crusher includes a base 1, a lower frame 11 mounted on the base 1, an upper frame 2 mounted above the lower frame, and a support plate 3 positioned on the outer side of the upper frame 2. A synchronous hydraulic system includes safety cylinders 5 connected to the upper frame 2 and the base 1, with an oil outlet pipe 9 connected to a throttle valve 7. A flow divider pipe 10 is mounted on the throttle valve 7, and the flow divider pipe 10 is connected to an oil supply pipe 4. The safety cylinders 5 are connected in parallel.
[0024] In this embodiment, the upper end of the safety cylinder 5 is connected to the support plate 3, and the lower end is connected to the base 1. The support plate 3 and the upper frame 2 are fixedly connected. Therefore, by operating the safety cylinder 5, the upper frame 2 can be raised and lowered. For cone crushers, when material jamming occurs, the upper frame 2 needs to be raised to widen the material leakage gap. This raising needs to be synchronized. If it is not synchronized, the upper frame 2 will tilt, which will lead to damage to the crushing head. To solve this problem, this technology uses a throttle valve 7. The throttle valve 7 can control the oil inlet speed of each node, and the throttle valves 7 are connected in parallel to achieve synchronized raising. Example
[0025] The throttle valve 7 is fixed on the base 1. The throttle valve 7 is connected to the oil inlet pipe 6 and is connected to the safety cylinder 5 through the oil inlet pipe 6. The safety cylinder 5 is connected to the oil outlet pipe 9 and is connected to the throttle valve 7 through the oil outlet pipe 9.
[0026] Unlike the above embodiments, in this embodiment, by setting a throttle valve 7, the oil inlet speed can be effectively controlled, thereby achieving synchronous operation of each safety cylinder 5. The throttle valve 7 is connected to an oil inlet pipe 6, which is connected to the oil inlet end of the safety cylinder 5, and is connected to the oil outlet end of the safety cylinder 5 through an oil outlet pipe 9. Example
[0027] The number of throttle valves 7 is several, and the throttle valves 7 are connected in parallel through the oil supply pipe 4. One throttle valve 7 controls two lifting nodes.
[0028] Unlike the above embodiments, in this embodiment, one throttle valve 7 corresponds to two safety cylinders 5, and one lifting node represents one safety cylinder 5. Example
[0029] The throttle valve 7 is connected to an accumulator for driving the throttle valve 7, and the oil supply pipe 4 is located on the outer side of the lower frame.
[0030] The working principle of this utility model:
[0031] In operation, this technology features a throttle valve 7 on the base 1. The throttle valve 7 is connected to the oil supply pipe 4, and then to the safety cylinder 5 via the oil inlet pipe 6 and the oil outlet pipe 9. An energy accumulator 8 is installed on the throttle valve 7. Excess impact force during operation can be absorbed by the energy accumulator 8. Due to the throttle valve 7, the oil inlet speed of each group of safety cylinders 5 can be controlled, thereby achieving synchronization of the safety cylinders 5 at different distances from the cylinders and realizing overall synchronization of the safety cylinders 5.
[0032] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
