Description

Technical Field

[0001] This utility model relates to the field of cone crusher technology, and more specifically, to an overload-proof hydraulic protection mechanism for cone crushers. Background Technology

[0002] Cone crushers are widely used in mining, metallurgy, building materials, chemical and other fields for medium and fine crushing. They are mainly used for crushing ores and rocks of various hardnesses. During operation, to prevent the crushing cone from being overloaded, a protective mechanism is needed to buffer the feeding of the material to be crushed. In actual use, cone crushers have the advantages of simple operation, stable structure and good conveying effect.

[0003] Existing protection mechanisms require multiple staggered plate structures to buffer the feeding of materials to be crushed. However, the angles of these staggered plate structures are fixed, making it impossible to adjust the feeding amount according to the crushing progress, which reduces the practicality of the existing protection structure. In addition, the use of magnetic column structures to screen iron materials among the materials to be crushed requires manual cleaning after the surface of the magnetic column structure is covered with iron material, which brings inconvenience to the use of the existing protection structure.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0018] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The hydraulic protection mechanism for an overload-resistant cone crusher includes a concave frame 1. Multiple sets of conveyor rollers 2 and multiple sets of electromagnetic rollers 3 are mounted inside the concave frame 1 via bearings. An electrical control box 7, a pump station, and two sets of mounting frames 8 are mounted at the lower part of the concave frame 1. A control panel is installed inside the electrical control box 7. Buffer frames 9 are installed on the far side of each of the two sets of mounting frames 8. Conveyor belts 6 are sleeved on the side walls of the multiple sets of conveyor rollers 2. A first self-locking reversible motor 5 is mounted on the end face of the concave frame 1, and the output end of the first self-locking reversible motor 5 is fixedly connected to the leftmost set of conveyor rollers 2 via a coupling, ensuring that the output end of the first self-locking reversible motor 5 can drive the leftmost set of conveyor rollers 2 to rotate. A mounting cover 4 is installed on the rear end face of the concave frame 1. Multiple sets of first mounting shafts 10 and multiple sets of second mounting shafts 11 are mounted inside the two sets of buffer frames 9 via bearings. First sleeve plates 12 are fixedly sleeved on the side walls of the multiple sets of first mounting shafts 10 on the same side, and first sleeve plates 12 are fixedly sleeved on the side walls of the multiple sets of second mounting shafts 11 on the same side. The device is equipped with a second connecting plate 13. A cover 14 is installed on the rear end face of both sets of buffer frames 9. A first gear 19 is fixedly sleeved on the rear end sidewall of multiple sets of first mounting shafts 10 on the same side. A second gear 20 is fixedly sleeved on the rear end sidewall of multiple sets of second mounting shafts 11 on the same side. A first hydraulic telescopic rod 15 and a second hydraulic telescopic rod 16 are fixedly inserted through the lower part of both sets of cover 14. A first serrated plate 17 is installed at the telescopic end of both sets of first hydraulic telescopic rods 15, and a second serrated plate 18 is installed at the telescopic end of both sets of second hydraulic telescopic rods 16. With the coordinated design of the first hydraulic telescopic rod 15, the second hydraulic telescopic rod 16, the first serrated plate 17, the second serrated plate 18, the first gear 19, and the second gear 20, the operating angle of the buffer structure can be precisely adjusted using the control panel according to the crushing progress, achieving flexible control of the feeding amount. This design breaks the limitation of the non-adjustable feeding amount and significantly improves the adaptability and practicality of the protection mechanism under different crushing conditions.

[0019] Please see Figure 3 , Figure 6 and Figure 7The worm gear 21 is installed inside the mounting cover 4 via bearings. Worm wheels 22 are fixedly sleeved on the rear side walls of multiple sets of electromagnetic rollers 3. A second self-locking reversible motor 23 is installed on the side wall of the mounting cover 4, and the output end of the second self-locking reversible motor 23 is fixedly connected to the worm gear 21 via a coupling, ensuring that the second self-locking reversible motor 23 can drive the worm gear 21 to rotate. The second self-locking reversible motor 23 is electrically connected to the control panel via wires, which can automatically adsorb and screen iron materials during the crushing process. After the material is conveyed, the electromagnetic rollers 3 are de-energized, which will cause the adsorbed iron materials to fall off automatically. With the help of the reverse-rotating conveyor belt 6, the iron materials are automatically collected and cleaned, reducing the intensity of manual operation and improving the convenience and efficiency of the hydraulic protection mechanism of the overload-proof cone crusher.

[0020] Please see Figure 6 The worm 21 meshes with multiple sets of worm wheels 22, and the rotating worm 21 can drive the multiple sets of worm wheels 22 to rotate.

[0021] Please see Figure 2 and Figure 5 On the same side, a set of first sawtooth plates 17 meshes with multiple sets of first gears 19 on the same side. The moving set of first sawtooth plates 17 on the same side can drive the multiple sets of first gears 19 on the same side to rotate.

[0022] Please see Figure 2 and Figure 5 On the same side, a set of second sawtooth plates 18 meshes with multiple sets of second gears 20 on the same side. The moving set of second sawtooth plates 18 on the same side can drive the multiple sets of second gears 20 on the same side to rotate.

[0023] Please see Figure 1 and Figure 2 The control panel is electrically connected to the pump station, multiple sets of electromagnetic rollers 3 and the first self-locking forward and reverse motor 5 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0024] Working principle: In actual use of the overload protection mechanism of the cone crusher, the control panel is used to activate the first self-locking reversible motor 5. The output of the first self-locking reversible motor 5 drives the leftmost set of conveyor rollers 2 to rotate. The rotating leftmost set of conveyor rollers 2 pushes the conveyor belt 6 to rotate. The rotating conveyor belt 6 can transport the material to be crushed. Then, using the control panel, the two sets of first hydraulic telescopic rods 15 and two sets of second hydraulic telescopic rods 16 are extended and retracted through the pump station. Since the first set of first sawtooth plates 17 on the same side meshes with the multiple sets of first gears 19 on the same side, the first set of first sawtooth plates on the same side moves up and down. 17 can drive multiple sets of first gears 19 on the same side to rotate. The multiple sets of first gears 19 on the same side can cause multiple sets of first socket plates 12 on the same side to rotate via multiple sets of first mounting shafts 10 on the same side. The vertically moving set of second serrated plates 18 on the same side can drive multiple sets of second gears 20 on the same side to rotate. The multiple sets of second gears 20 on the same side can cause multiple sets of second socket plates 13 on the same side to rotate via multiple sets of second mounting shafts 11 on the same side. When the multiple sets of first socket plates 12 and multiple sets of second socket plates 13 on the same side are rotated to the operating angle, the two sets of first hydraulic telescopic rods 15 and two sets of second hydraulic telescopic rods 16 are stopped via the control panel and the pump station. To prevent telescopic movement, the first mounting shaft 10, the first connecting plate 12, and the second connecting plate 13 allow for convenient adjustment of the operating angle of the buffer structure, improving the practicality of the hydraulic protection mechanism for the overload-resistant cone crusher. Simultaneously, as described above, the material to be crushed is conveyed by the rotating conveyor belt 6. At the same time, the second self-locking forward / reverse motor 23 is activated via the control panel. The output of the second self-locking forward / reverse motor 23 drives the worm gear 21 to rotate. Since the worm gear 21 meshes with multiple sets of worm wheels 22, the rotating worm gear 21 can push the multiple sets of worm wheels. The rotating worm gear 22 drives multiple sets of electromagnetic rollers 3 to rotate. The rotating sets of electromagnetic rollers 3 can be energized to attract iron material between the materials to be crushed. After the materials to be crushed are conveyed, the control panel is used to de-energize the multiple sets of electromagnetic rollers 3. The iron material attracted on the surface of the multiple sets of electromagnetic rollers 3 will fall onto the conveyor belt 6. Then, the control panel is used to make the output end of the first self-locking forward and reverse motor 5 rotate in the opposite direction. The reverse rotating conveyor belt 6 can transport iron material. The electromagnetic rollers 3 and the mounting cover 4 make it easy to clean the attracted iron material, which brings convenience to the use of the hydraulic protection mechanism of the overload-proof cone crusher.
