Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a protective device for a cone crusher. Background Art

[0002] When the cone crusher is working, the motor drives the eccentric sleeve to rotate through the horizontal shaft and a pair of bevel gears. The axis of the crushing cone makes a pendulum motion under the force of the eccentric sleeve, so that the surface of the crushing wall sometimes approaches and sometimes leaves the surface of the mortar wall, so that the ore is constantly squeezed and bent in the crushing chamber and crushed. The outer casing of the cone crusher needs to be wrapped by a protective device to achieve a protective effect and reduce the impact of external force on the outer casing of the cone crusher.

[0003] The protective device can wrap the outer shell of the cone crusher. The material to be crushed is put into the crusher through the top of the protective device. The protective device can guide the material. The opening area at the top of the protective device remains unchanged, so the input material will all be guided into the crusher. When the amount of material is large, the crushing speed of the crushing roller slows down, which reduces the practicality of the protective device. The impact force between the material and the inner surface of the protective device is relatively large, and the device is damaged to a large extent. Therefore, a protective device for cone crusher is designed. Utility Model Content

[0021] See also Figure 1-4 The utility model provides a technical solution for a protective device for a cone crusher:

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, a protective device for a cone crusher comprises an upper protective cover 1 and a lower protective cover 2. The lower protective cover 2 is arranged at the bottom of the upper protective cover 1. A feeding box 3 is arranged on the top of the upper protective cover 1. An adjusting frame 11 is slidably installed inside the feeding box 3. A smooth rod 4 is arranged inside the feeding box 3. A moving block 5 is sleeved on one end of the smooth rod 4. A limiting frame 8 is arranged on the top of the upper protective cover 1. A micro motor 9 is arranged on the top of the limiting frame 8. A restraining rod 6 is arranged on one side of the moving block 5. A sponge pad 12 is arranged on the surface of the adjusting frame 11. A pressure-resistant layer 13 is arranged on the inner wall of the upper protective cover 1. Two buffer pads 15 are arranged inside the upper protective cover 1. When the gear 10 rotates counterclockwise, it drives the rack 7 meshing with it to move leftward, and the moving block 5 moves leftward at one end of the smooth rod 4, so that the adjusting frame 11 gradually moves to the inside of the feeding box 3. At this time, the area through which the material can pass is reduced.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, two reinforcement frames 14 are arranged on the surface of the pressure-resistant layer 13, the bottom ends of the two buffer pads 15 are respectively fixedly connected to the top ends of the two reinforcement frames 14, and the surfaces of the two buffer pads 15 are arranged with silica gel. The positions where the two buffer pads 15 are arranged correspond to each other. The utility model is a protective device for a cone crusher, which is provided with a pressure-resistant layer 13, a reinforcement frame 14, a buffer pad 15 and a sponge pad 12. The sponge pad 12 covers the surface of the adjustment frame 11. The silica gel arranged on the surface of the buffer pad 15 and the sponge pad 12 have a certain softness, which reduces the impact force of the material on the two.

[0026] Working principle: When the cone crusher is working, the motor drives the eccentric sleeve to rotate through the horizontal shaft and a pair of bevel gears. The axis of the crushing cone performs a pendulum motion under the force of the eccentric sleeve, so that the surface of the crushing wall sometimes approaches and sometimes leaves the surface of the mortar wall, so that the ore is constantly squeezed and bent in the crushing chamber and crushed. The outer shell of the cone crusher needs to be wrapped by a protective device to achieve a protective effect and reduce the impact of external force on the outer shell of the cone crusher. The upper protective cover 1 and the lower protective cover 2 can be installed on the outer surface of the cone crusher to achieve a protective effect. The material is transported to the inside of the cone crusher through the feed box 3 for crushing. After starting the micro motor 9, it will drive the gear 10 to rotate synchronously. When the gear 10 rotates counterclockwise, Then it drives the rack 7 meshing with it to move to the left, and the moving block 5 moves to the left at one end of the smooth rod 4, so that the adjusting frame 11 gradually moves to the inside of the feeding box 3. At this time, the area through which the material can pass is reduced. Therefore, by moving the adjusting frame 11, the amount of material entering the crusher can be adjusted. After the adjusting frame 11 gradually moves outward, the area through which the material passes gradually increases. The sponge pad 12 covers the surface of the adjusting frame 11. The silica gel and sponge pad 12 arranged on the surface of the buffer pad 15 have a certain softness, which reduces the impact force of the material and the two, and extends the service life of the adjusting frame 11 and the buffer pad 15. After the material impacts the buffer pad 15, the speed of material transportation is reduced, thereby reducing the impact force of the material and the cone crusher.
