The invention discloses a striker plate (10) for a paver, wherein the striker plate (10) comprises a fixed baffle plate (1) and a movable baffle plate (2); and the movable baffle plate (2) is rotatably connected on the lower end of the fixed baffle plate (1) so as to adjust the integral height of the striker plate (10). The invention further discloses a paver. The integral height of the striker plate is adjustable so as to be adapted to operating requirements of the paver under different working conditions, so that the materials can be prevented from falling and separating to ensure paving quality.

The invention provides a screed height-difference adjusting device, a paver and a screed high-difference adjusting method. The screed height-difference adjusting device is used for adjusting the height difference between an auxiliary screed and a main screed of the screed, and comprises an angle sensor, an adjusting oil cylinder and a controller, wherein the angle sensor is used for measuring working elevation angle of the main screed; the adjusting oil cylinder is used for driving the auxiliary screed to displace in the height direction; and the controller is used for receiving the working elevation angle measured by the angle sensor, calculating the target displacement of the auxiliary screed in the height direction according to the working elevation angle, and controlling the height difference between the auxiliary screed and the main screed by controlling the adjusting oil cylinder. By virtue of the technical scheme, the angle sensor reads out the working elevation angle of the main screed and the auxiliary screed, and the adjusting oil cylinder determines the to-be-adjusted height value according to the working elevation angle to automatically flex and adjust the height difference. Therefore, the manual work is avoided; and time and force are saved. Meanwhile, the precision of the adjusting value calculated according to the working elevation angle is higher; the evenness of the paved road surface is ensured; and the paving quality of the road is improved.

The invention discloses a concrete pavement paving device and method based on a weaving mechanism. The paving device comprises a rack, a concrete feeding device, a horizontal vibrator and a vertical vibrator, wherein the rack horizontally moves from back to front in the pavement paving direction, and the concrete feeding device moves along with the rack; the horizontal vibrator is positioned above the front side of the rack, and the vertical vibrator is positioned above the rear side of the rack. The concrete feeding device is arranged in the wideness direction of a pavement. The paving method comprises the following steps: the rack horizontally moves from back to front in the pavement paving direction, and pavement anti-deformation structures are arranged on the base layer of the paved pavement from back to front in the moving process; in the process that the rack moves from back to front, the concrete feeding device continuously conveys concrete in the concrete feeding device onto the base layer of the pavement for paving in multiple paving stripes from back to front based on the weaving mechanism. The concrete pavement paving device has the advantages of reasonable design, simpleness and convenience in use and operation, high efficiency, energy saving, high paving quality and easiness in promotion and use and can solve various inherent contradictions and problems in sliding mode paving construction.

The invention provides a screed and a paver comprising the same. The screed includes at least one plate section and a screed heating system, wherein the plate section comprises a box body and a box body base plate. The screed heating system consists of an accommodating chamber, a heating device and a circulation device, wherein the accommodating chamber is arranged inside the plate section box body and contacted with the box body base plate, and comprises thermal fluids used for heating the box body base plate; the heating device is used to heat the thermal fluids; the circulation device is connected through the accommodating chamber to drive the thermal fluids to cycle between the circulation device and the accommodating chamber. The screed in the invention speeds up the heat-transfer efficiency of the thermal fluids, thus enabling the box body base plate of the screed to be evenly heated, and also enhances the quality of the road paving by reducing the uneven heating degree and deformation induced by thermal stress of the body box base plate.

The invention discloses automatic cement road paving equipment which comprises a base, a floor arranging part, a cement stirring part, a floor paving part, four travelling parts and a floor storing part. The lower portion of a third stepping motor support base support post of the cement stirring part is mounted on a cement stirring part support base. Four sliding blocks are mounted in dovetail grooves in the inner side faces of two cement stirring part mounting plates in a sliding mode. Steering gears of the four travelling parts are mounted in four steering gear fixing bases. Two dovetail groove supporting plates of the floor storing part are mounted on a bottom plate. According to the automatic cement road paving equipment, two third hydraulic cylinders drive the floor paving part to descendby a certain distance, two fourth hydraulic cylinders drive a fourth hydraulic cylinder roof plate so as to drive a paving post fixing plate, accordingly paving posts are driven to pave a floor, the floor is automatically paved, manpower is greatly saved, and the floor paving quality is improved.
