Description

Technical Field

[0001] The utility model relates to the technical field of impact crushers, in particular to an impact crusher with a vibration reduction effect. Background Art

[0002] An impact crusher, also known as a counterattack crusher, is a new, highly efficient crushing device that utilizes impact energy to break materials. The operating principle of an impact crusher is based on the impact crushing of materials on a high-speed rotating rotor and the mutual impact crushing of materials. When material enters the crusher, it is first struck by the hammers on the high-speed rotating rotor, causing the initial impact crushing. Subsequently, the crushed material is thrown onto the impact plate, where it is subjected to a second impact crushing. Repeated impacts between the rotor and the impact plate crush the material until it reaches the desired particle size.

[0003] Based on the above working principle, the impact crusher will inevitably have more obvious vibration when in use. Since the impact crusher is in a vibrating state as a whole during operation, its bottom will produce high-frequency vibration collision with the ground or the installation platform. If it is not handled, it will cause the ground or the installation platform to be damaged by vibration over time, and the bottom of the crusher will be severely worn, shortening its service life. At the same time, vibration will also generate noise, affecting the physical and mental health of workers. Therefore, in response to the above problems, an impact crusher with vibration reduction effect is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an impact crusher with a vibration reduction effect. The impact crusher supports the crusher body with a heat dissipation and vibration reduction mechanism. The vibration energy generated by the crusher body when working will be dissipated in the form of heat by the damper through reciprocating motion, thereby playing a vibration reduction role, and then protecting the ground and the crusher body, and at the same time reducing noise. In particular, in order to accelerate the heat loss rate of the damper, the cooling pipe arranged outside the damper can quickly take away the heat through a water cooling cycle, ensuring that the vibration reduction effect does not show obvious attenuation and maintains a high vibration reduction level. In addition, in order to prevent the crusher body from shaking left and right during the vibration reduction process, a guide member is also provided, which is used to constrain the crusher body to move only in the vertical direction, solving the technical problem in the prior art that the impact crusher is in a vibrating state as a whole when working, which will cause the ground or the mounting platform to be damaged by vibration in the long run, and will also cause serious wear on the bottom of the crusher, shortening its service life, and vibration will also generate noise, affecting the physical and mental health of workers.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] An impact crusher with a vibration-damping effect comprises a base plate, a crusher body is arranged above the base plate, a heat dissipation and vibration-damping mechanism for supporting the crusher body, and a guide member for constraining the crusher body to move only in the vertical direction, wherein the heat dissipation and vibration-damping mechanism comprises a damper, an adjustable spring return member is installed on the damper, a cooling pipe is provided on the damper housing, and the cooling pipe comprises a spiral tube, and the two ends of the spiral tube are respectively connected to a water inlet pipe and a water outlet pipe.

[0018] In a possible implementation, lubricating oil is contained in the guide cylinder, and a plurality of oil overflow grooves arranged in a circumferential array are provided on the inner wall of the guide cylinder.

[0019] Through the above-mentioned structural form, the lubricating oil can play a lubricating role, reducing the friction between the guide shaft and the guide cylinder when the guide shaft slides. When the guide shaft moves downward, the lubricating oil can be squeezed and moved upward along the oil overflow groove, so that the lubricating oil is evenly applied to the surface of the guide shaft to ensure the lubrication effect.

[0034] like Figure 1 - Figure 2As shown, a cooling circulation pipe 5 is laid on the base plate 1, which is used to provide circulating cooling water for the cooling pipe 33. The cooling circulation pipe 5 includes a water inlet main pipe 51 and a water outlet main pipe 52. The water inlet main pipe 51 and the water outlet main pipe 52 can provide the necessary structural basis for the circulation of cooling water. A number of connecting branches 53 are connected to the water inlet main pipe 51 and the water outlet main pipe 52, wherein the water inlet pipe 332 is tightly connected to the water inlet main pipe 51 through the connecting branch pipe 53, and the water outlet pipe 333 is tightly connected to the water outlet main pipe 52 through the connecting branch pipe 53. Through the above-mentioned structural form, the cooling water enters the water inlet pipe 332 through the water inlet main pipe 51 under the action of the external pump body, and flows outside the damper 31 through the spiral tube 331, taking away the heat generated by the damper 31, and the heated water is discharged into the water outlet main pipe 52 through the water outlet pipe 333 to complete the circulation.

Specifically, under the action of the external pump body, the cooling water enters the water inlet pipe 332 through the water inlet main pipe 51, and flows outside the damper 31 through the spiral tube 331, taking away the heat generated by the damper 31, and the heated water is discharged into the water outlet main pipe 52 through the water outlet pipe 333, completing the cycle.

[0041] In the above process, in order to prevent the crusher body 2 from shaking left and right during the vibration reduction process, a guide member 4 is further provided, which is used to constrain the crusher body 2 to move only in the vertical direction. Specifically, the guide shaft 42 can slide in the guide cylinder 41 to limit the crusher body 2 to move only in the vertical direction during vibration.
