[0002] Cone crusher is a kind of crushing machine suitable for raw materials in metallurgy, construction, road construction, chemical and silicate industries. It is widely used. When the crusher is working, it will produce great vibration, so there is a certain demand for cone crusher vibration reduction device.

[0003] Most of the existing cone crusher vibration reduction devices are single vibration reduction structures, and the structures are mostly fixed. The crusher generates strong vibrations when working, which makes the vibration reduction spring have a large range of motion. Although the equipment can stably reduce vibration, the overall movement amplitude is large, the vibration reduction effect is not good, and there are certain safety issues. Summary of the invention

[0006] Furthermore, a second slide groove is provided on the upper end surface of the fixing seat, and a sliding block is slidably connected inside the second slide groove.

[0007] Furthermore, a connecting rod is rotatably connected between the slider and the connecting piece, and an airbag is fixedly installed between the slider and the inner left end surface of the second slide groove.

[0008] Furthermore, the left end of the airbag is connected to a gas outlet, and the diameter of the gas outlet is much smaller than the diameter of the airbag.

[0009] Furthermore, the connecting rod, the sliding block, the second sliding groove, the airbag and the air outlet are each provided with two groups correspondingly and are symmetrically arranged.

[0010] Furthermore, the two groups of connecting rods are rotatably connected to the connecting piece, and a second spring is fixedly installed between the two groups of sliding blocks.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model arranges spring 1, spring 2 and an air bag, and utilizes spring 1 and spring 2 to buffer the vibration generated by the crusher. At the same time, the air bag is squeezed, and the gas in the air bag is discharged from the air outlet. The diameter of the air outlet is limited, so the amplitude of the crusher will not be too large, thereby improving the stability of the crusher. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 , the utility model provides a technical solution:

[0022] A cone crusher vibration reduction device comprises a fixed seat 1, a sleeve 2 is fixedly installed on the upper end surface of the fixed seat 1, a slide plate 3 is slidably connected inside the sleeve 2, a transmission column 5 is slidably connected to the upper end of the sleeve 2, a crusher body is fixedly installed on the upper end of the transmission column 5, the lower end of the transmission column 5 extends to the inside of the sleeve 2 and is fixedly connected to the slide plate 3, a spring 4 is fixedly installed between the slide plate 3 and the inner upper end of the sleeve 2, a connecting piece 6 is fixedly installed on the lower end of the slide plate 3, a slide groove 7 is provided on both sides of the outer surface of the sleeve 2, and both ends of the connecting piece 6 are slidably connected to the slide groove 7.

[0023] A second slide groove 8 is provided on the upper end surface of the fixing seat 1, a slider 9 is slidably connected inside the second slide groove 8, a connecting rod 12 is rotatably connected between the slider 9 and the connecting member 6, and an airbag 10 is fixedly installed between the slider 9 and the inner left end surface of the second slide groove 8.

[0024] When the cone crusher vibration reduction device is used, when the crusher is working, the vibration generated is transmitted to the transmission column 5, the transmission column 5 will drop, and the slide plate 3 will drop. The spring 1 4 on the slide plate 3 will first buffer, and at the same time the slide plate 3 will drive the connecting member 6 to drop, and the connecting member 6 will transfer the downward force to the slider 9 through the connecting rod 12, so that the two groups of sliders 9 are displaced to both sides and pull the spring 2 13, which buffers it.

[0025] The left end of the airbag 10 is connected to a gas outlet hole 11 , and the diameter of the gas outlet hole 11 is much smaller than the diameter of the airbag 10 .

[0026] The connecting rod 12, the slider 9, the second slide groove 8, the airbag 10 and the air outlet 11 are respectively provided in two groups and are symmetrically arranged. The two groups of connecting rods 12 are rotatably connected to the connecting member 6, and the second spring 13 is fixedly installed between the two groups of sliders 9.

[0027] At the same time, the slider 9 will squeeze the airbag 10, so that the gas in the airbag 10 is discharged from the air outlet 11, but the diameter of the air outlet 11 is limited, so the gas discharged within a stage time is also limited, so the crusher will not vibrate too much, thereby improving the stability of the crusher.

[0028] The utility model arranges spring 1 4, spring 2 13 and air bag 10, and utilizes spring 1 4 and spring 2 13 to buffer the vibration generated by the crusher, and at the same time squeezes the air bag 10, and the gas in the air bag 10 is discharged from the air outlet 11. The diameter of the air outlet 11 is limited, so the amplitude of the crusher will not be too large, thereby improving the stability of the crusher.

[0029] Working principle: When the cone crusher vibration reduction device is used, when the crusher is working, the vibration generated is transmitted to the transmission column 5, and the transmission column 5 will drop and cause the slide plate 3 to drop. The spring 14 on the slide plate 3 will first be buffered, and at the same time, the slide plate 3 will drive the connecting piece 6 to drop, and the connecting piece 6 will transmit the downward force to the slider 9 through the connecting rod 12, so that the two groups of sliders 9 will move to both sides and pull the spring 2 13. The spring 2 13 will buffer it and at the same time, the slider 9 will squeeze the airbag 10, so that the gas in the airbag 10 will be discharged from the air outlet 11, but the diameter of the air outlet 11 is limited, so the gas discharged within a stage time is also limited, so the amplitude of the crusher will not be too large, thereby improving the stability of the crusher.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
