Problems solved by technology

However, the hammer impact crushing method is difficult to separate the steel bars from the concrete in practice.
Therefore, the heavy hammer impact crushing process represented by large multi-hammer crushers and impact compaction crushers has fatal flaws that are difficult to overcome.
[0006] The above equipment is currently the main equipment for concrete crushing construction, all of which have large noise pollution, large dust during operation, uneven size of concrete after crushing, easy to form reflection cracks, not easy to recycle, and low efficiency

Embodiment Construction

[0026] see figure 1 As shown in the figure, it shows a schematic diagram of the overall structure of the resonance crusher of the present invention. The resonance crusher is mainly composed of a control system 1, a cooling system 2, a hydraulic system 3, a vibration crushing system 4, a vehicle system 5, and a power system 6. composition.

[0027] Firstly, the control system 1 is introduced. The control system 1 is mainly composed of components such as the cab, electrical cabinet, steering gear and control handle. , vibration start and stop, vibration frequency adjustment and other specific controls.

[0028] Looking at the cooling and dust pressing system 2 again, its specific structure is as follows: figure 2 As shown, the cooling and dust pressing system 2 is mainly composed of a water tank 21, a water pump 22, a pressure gauge 23, a safety valve 24, a cooling water channel 25, and a dust pressing nozzle 26. The water pump 22 is placed above the water tank 21, and the pr...

Abstract

The invention relates to a resonance crusher which comprises a control system, a cooling and dust suppressing system, a hydraulic system, a vibration crushing system, a vehicle system and a power system, wherein the vibration crushing system comprises a lifting system, a traversing system, a shock absorbing system, a shock excitation system, a mounting system and a transmission system; the shock excitation system comprises a shock excitation case, an eccentric block and a crushing hammer head, wherein a vibration bearing, a vibration shaft, gears and lubricating oil are installed in the shockexcitation case, and a water-cooling channel is arranged in the shock excitation case; the multiple eccentric blocks are suspended outside the shock excitation case in a staggered arrangement mode; and the crushing hammer head is connected to the lower part of the shock excitation case by bolts.

Description

technical field [0001] The invention relates to the technical field of highway construction machinery, road construction machinery and road surface maintenance machinery, in particular to a resonance crusher used for crushing construction operations on concrete road surfaces such as highways and airports. Background technique [0002] There are a large number of old concrete pavements in my country and around the world that need to be renovated. Different degrees of engineering practice have been carried out all over the world, and various processes and methods have been tried out, but an ideal method has not been found that can meet the requirements of high efficiency, low cost and long life. [0003] Early concrete pavement reconstruction projects were mainly to add a new layer of concrete or asphalt concrete (white to black) after some roughening of the old surface. However, due to the existence of defects such as reserved seams, cracks, potholes, detached edges, and ins...
