Paver screed satisfying transverse vibration uniformity

Abstract

The invention discloses a paver screed satisfying transverse vibration uniformity, comprising a combined type screed which is composed of a plurality of sections of screeds, wherein, vibrators are arranged on a plurality of sections of screeds; each vibrator comprises a partiality axis, a bearing arranged on the partiality axis and a bearing base fixed on the screed, wherein, the partiality axis is provided with a power driving mechanism connected with a power source; the nominal amplitudes of a plurality of sections of screeds are identical and are equal to a constant of A0, namely, Ai=mi*eI / Mi=A0=(sigma mi*ei) / sigma Mi, wherein, the mass of the partiality axis mi=Fi*Li*rho, a partiality distance ei=ai*D<2>i / (D<2>i-d<2>i), the section area of the partiality part of the partiality section of the partiality axis Fi=pi*(D<2>i-d<2>i) / 4, wherein, Li is the length of the partiality section of the partiality axis, rho is material density of the partiality axis, Di is cylinder diameter of the partiality section of the partiality axis, di is cylinder diameter of journal of the partiality axis and alpha is the space between the cylinder axis of the partiality section of the partiality axis and the cylinder axis of journal. The invention has the advantages of reasonable design, convenient improvement method, good improvement effect and reliable work performance and can effectively solve the problem of poor transverse vibration uniformity along screed width direction of paver in work.

Description

technical field [0001] The invention relates to a paver screed, in particular to a paver screed satisfying the uniformity of lateral vibration. Background technique [0002] Paver is one of the key equipment necessary for paving roads of various grades. As the core working device of the paver, the screed is used to pre-press, shape and level the mixture paved by the auger, so as to create the necessary conditions for the subsequent rolling of the road roller. It is to ensure the paving One of the key devices of quality is directly related to the performance of products and the quality of road construction. At present, vibrators are installed on the screeds used in paver machines at home and abroad, which force the screed to vibrate through the centrifugal force generated when the eccentric shaft rotates at high speed, thereby improving the compaction of the virtual pavement mixture and making the paver The laminate is dense and the surface is smooth. Since the screed of t...
