Road surface crusher

Abstract

The invention discloses a pavement breaker, which comprises a fuselage supported by a crawler-type chassis, an engine is arranged in the fuselage, and an arm-type transmission mechanism, the head end of the arm-type transmission mechanism passes through a pin that can rotate around it One is movably connected to the fuselage, and the end of the arm transmission mechanism is movably connected with the wrench that pulls the road surface through pin two. They are respectively connected with the arm hydraulic station placed in the fuselage through a hydraulic circuit. Compared with the traditional way of breaking the pavement with a breaker, the invention has low noise, high efficiency, and little self-loss during operation, which not only improves the service life of the equipment, but also reduces the maintenance cost.

Description

technical field [0001] The invention relates to a road construction device, in particular to a road surface crusher for crushing an original road surface, which belongs to the field of engineering machinery. Background technique [0002] The rapid development of cities and industries has put forward higher requirements for roads and traffic, and some roads have become less and less suitable for the needs of reality due to the defects of low grade and narrow road surface, and even restrict the development of a city. Therefore, in urban and rural areas across the country, vigorous scenes of road and bridge construction can be seen everywhere. To renovate or renovate the existing pavement, the original pavement must be destroyed first, and then paved again. This kind of damage to the original road surface is nothing more than two ways of manual and machine equipment. In large-scale construction occasions, machinery and equipment are used more, and this equipment is the paveme...

AI Technical Summary

Problems solved by technology

[0003] These crushing devices have the following prominent problems: 1. Loud working noise and low efficiency; 2. It has a great impact on the service life of the machine, especially the force arm is easily damaged, and the seismic performance of the material is very high; 3. The pavement is broken or broken by overcoming the compressive strength of the pavement, which requires a higher impact force on the crushing device, because the compressive strength of the pavement material is much larger than the tensile strength; 4. The energy utilization level is low, and the wearing parts need to be replaced Frequent; 5. The stability requirements of the crusher are high; 6. High requirements for safety performance

[0004] The above shortcomings are no longer suitable for the development of machinery and equipment for the current road construction, which not only affects the daily life and travel of residents around the construction site, but also slows down the construction progress, resulting in increased construction time and equipment costs
