Floating mechanism for resonant crusher

Abstract

The invention discloses a floating mechanism for a resonant crusher, comprising a car body, a vibration device, a longitudinal moving slide block, a longitudinal moving slide block linking plate, a transverse moving upper chute, a longitudinal moving chute, a transverse moving oil cylinder, a longitudinal moving oil cylinder, a transverse moving lower chute and a transverse moving slide block. The mechanism can realize up-down free floatation and transverse movement of the vibration device, and sequentially realizes the full-width crushing effect in equipment construction, in the construction, dead angle is avoided, and a crushing tool bit always fits the road surface tightly during construction so as to adapt to the up-and-down conditions of the road surface well.

Description

Technical field [0001] The invention relates to the technical field of highway engineering machinery, road construction machinery and road maintenance machinery, and in particular to a floating mechanism of a resonance crusher used for the crushing construction work of concrete pavements such as highways and airports. Background technique [0002] In the process of refurbishing the dilapidated concrete pavement, if an asphalt layer is directly added to the old surface layer, the overall strength of the reconstructed pavement will be poor due to the original defects of the old cement layer. Under the continuous impact of vehicle load, The old surface layer will have uneven bearing capacity, causing stress concentration and reflection to the upper layer, causing cracks in the new surface layer. In order to completely solve the fatal impact of the old pavement on the newly paved pavement, the old cement pavement needs to be resonantly broken to form a stable broken layer in which th...

Problems solved by technology

For the American resonance crushing equipment in the prior art, the existing problems mainly include: (1) The crushing cutter head of the vibration device of the American equipment can be in contact with the road surface and crushed under the control of the hydraulic cylinder, but it cannot be broken in time according to the fluctuation of the road surface. Adjust the up and down position, and there will be a phenomenon that the concave position cannot be broken; (2) The vibrating device of the American equipment cannot move laterally, and the vibrating device is on the inner side of the tire, and the crushing knife head is about 1 meter away from the outer edge of the tire Therefore, during construction, the edge of the road cannot be broken, that is, there is a dead angle in the construction; (3) The vibration device of the American equipment adopts the oil cylinder that is always connected to adjust the upper and lower positions, and the oil cylinder cannot be separated, and the vibration device vibrates greatly during construction It is easy to transmit the vibration to the car body, causing damage to other components and discomfort to the operator.
