Parallel connection rod turning mechanism for resonance crusher

Abstract

The invention discloses a parallel connection rod turning mechanism for a resonance crusher. The parallel connection rod turning mechanism comprises a vertical hinge 2, turning cylinders 3, parallel connection rods 4, a support frame 5 and swing arms 6. With the mechanism, sufficient installation spaces are provided for the turning cylinders 3, chambers with the rod and rod-free chambers of the two turning cylinders are connected by adopting a cross parallel connection manner, and a characteristic of the same turning-left speed and the turning-right speed is provided so as to effectively increase equipment operation flexibility, and ensure uniformity of the turning speed; and the dual connection rod mechanism is adopted, such that tension of only the one connection rod is ensured when turning force is transmitted from one side to the other side, and reliability and stability of the mechanism work are effectively improved.

Description

technical field [0001] The invention relates to the technical fields of road construction machinery, road construction machinery and road surface maintenance machinery, in particular to a parallel link steering mechanism for a resonance crusher used for crushing construction operations on concrete road surfaces such as roads and airports. Background technique [0002] In the renovation process of dilapidated concrete pavement, if the 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, resulting in stress concentration and reflection to the upper layer, causing cracks to appear in the new surface layer paved. In order to completely solve the fatal impact of the old pavement on the new pavement layer, the old cement pavement needs to be resonantly broken t...

Problems solved by technology

At present, the steering mechanism used for resonance crushers and some construction machinery in the market mainly adopts the articulated steering method controlled by double oil cylinders, which is arranged in the middle of the equipment. Such a steering method makes it impossible to realize the operation of a large local steering angle when the equipment is operated. , and the steering power is provided by articulated double oil cylinders. When the steering wheel is controlled by the hydraulic control steering wheel, it is prone to the problem of inconsistency between the left and right steering speeds.
