Cement concrete pavement resonance crusher

Abstract

The invention discloses a cement concrete pavement resonance crusher. The crusher comprises a machine body, wherein a cab is arranged at the top of the machine body, a water tank and travelling wheelsare arranged at the bottom of the machine body, the water tank is positioned on one sides of the travelling wheels, a supporting box is arranged inside the machine body, a first supporting seat is arranged at the top of the interior of the supporting box, a second supporting seat is arranged at the position of the side, close to the first supporting seat, of the bottom of the interior of the supporting box, one end of the first supporting seat and one end of the second supporting seat are rotationally connected with a resonance beam through rotating shafts, and a rod hole is formed inside theresonance beam. According to the crusher, a vibration excitation eccentric wheel rotates to generate eccentric force, vibration energy is transmitted to a crushing hammer through the resonance beam amplitude modulation and frequency modulation, so that the vibration frequency of the crushing hammer reaches the inherent frequency of a cement panel, a plate resonates and rapidly cracked, and the cement concrete plate is promoted to be subjected to resonance cracking, and therefore cracked but not broken.

Description

technical field [0001] The invention belongs to the technical field of resonance crushing, and in particular relates to a cement concrete pavement resonance crusher. Background technique [0002] Resonance crushing technology has been widely used in dozens of countries such as the United States and Europe. It was introduced to China in 2006 and has been widely used in Shanghai, Zhejiang, Fujian and other places, with a cumulative construction volume of more than 8 million m2 , has proved the maturity, reliability and applicability of resonance crushing technology. [0003] However, the pavement crushers currently on the market tend to cause large surface crushing particle sizes when crushing roads. Although the residual strength of the structure is high, it is easy to produce launch cracks, and the thickness of the overlay is large. The crushing impact is strong, which has a great impact on surrounding buildings and underground pipelines. , It is not suitable for urban road...
