Novel concrete pavement resonance stone crushing equipment and usage method thereof

Abstract

The invention discloses novel concrete pavement resonance stone crushing equipment which comprises a frame, a plurality of wheels and a resonance stone crushing device are arranged at the bottom end of the frame, and the wheels are rotationally connected with the frame; the resonance stone crushing device comprises a fixing block in sliding connection with the frame, the bottom end of the fixing block is fixedly connected with an excitation generation mechanism through an elastic transmission assembly, and a gap is reserved between the excitation generation mechanism and the fixing block; the excitation generation mechanism comprises a generation box body fixedly connected with the elastic transmission assembly, and a shock excitation generation assembly is rotationally connected into the generation box body; a motor is fixedly connected to the top end of the generation box and is in transmission connection with the excitation generation assembly. The bottom end of the excitation generation mechanism is fixedly connected with a hammer head. The equipment can better crush a cement pavement. The full-road-width and full-road-surface crushing requirement can be met.

Description

Technical field [0001] TECHNICAL FIELD The present invention relates to road construction, in particular, it relates to a novel Gravel concrete pavement of resonance apparatus and methods of use. Background technique [0002] Rubblization resonance by a resonance principle is the old cement concrete pavement with a mechanical resonance phenomenon crushing, crushed into a top old cement concrete pavement Interlocking each other, the lower mutually interlocking concrete aggregates gravel layer. Gravel crushed shape complementary to adjacent, smaller particle size, a stable structure of another Interlocking, to solve the original cracks in cement concrete pavement, the horizontal and vertical displacement of the joints, eliminating the original plate crack up reflected stress, strength and stiffness of the layer above the graded gravel, affect the old road foundation is small, is the solution to concrete Pavement effective means of reflection cracks prone. [0003] However, the exis...

Problems solved by technology

[0003] However, the existing resonance crushing equipment is often imported from abroad, but because the foreign resonance crushing equipment often uses beam vibration, its frequency is fixed at about 44Hz, but this frequency is not enough to meet the resonance crushing requirements of domestic cement pavement. demand; and the crushing hammer head of this kind of equipment is set in the middle of the front of the vehicle, which makes it impossible to break the cement concrete board within 1.5 meters on both sides of the road
