Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the structure of the high-density compound screed of the present invention is divided into three parts: the front screed, the rear screed and the connecting mechanism. The structure of the front screed is the same as that of the traditional mechanical widening screed, mainly including the front main screed 1, the front widening screed connected by bolts on both sides of the front main screed 3, and the two sides of the front widening screed connected by bolts The front screed end dam 4 and the front screed heating system 2 installed behind the front main screed and the front widening screed. The front main screed has the same structure as the traditional mechanical widening screed, mainly including the left and right main frames 16, the vibrating mechanism 15, the vibrating mechani...

The invention belongs to the technical field of asphalt concrete paver screed in construction machinery, and in particular relates to a high-density compound screed for a paver, including two screeds arranged at the front and rear and a connecting mechanism connecting the two screeds. The two screeds arranged at the front and rear are respectively the front screed and the rear screed. The front screed can be installed on the main arm of the paver, the connecting mechanism is installed on the front screed, and the rear screed is installed on the connecting mechanism. The mechanism can lift the rear screed and adjust the elevation angle of the rear screed. When the present invention works, the asphalt mixture is preliminarily paved and compacted by the front screed, and then the asphalt mixture is further compacted by the high-frequency vibration of the rear screed, and then smoothed to form the final road surface after reaching high density. The invention has a compact and flexible structure, can shorten the construction period, save construction cost, improve construction efficiency, open traffic in a short time, and reduce the number of on-site workers and construction equipment.
Description
technical field [0001] The invention belongs to the technical field of asphalt concrete paver screeds in construction machinery, and in particular relates to a high-density compound screed for pavers. Background technique [0002] Asphalt paver is a special machine for laying asphalt pavement or stabilizing base material. It lays asphalt concrete or stabilizing materials on the road according to the required road width, camber and thickness, flatness and compactness. The screed is one of the main working devices of the asphalt paver. It is to shape, compact and iron the asphalt mixture spread by the screw conveyor according to the width, thickness and camber required by the road construction. The whole screed forms a set of suspension devices. floating state. The screed is divided into mechanical widening screed and hydraulic expansion screed according to the extension method. At present, whether it is a mechanical widening screed or a hydraulic telescopic screed, the pa...
