Abstract

The invention relates to the spreading machine field, which discloses a spreading machine, and a method and device for controlling material level of the spreading machine. The method includes detecting a material level of the spreading machine; setting control parameters of an actuating mechanism according to parameters of the actuating mechanism of the spreading machine; calculating a practical productivity coefficient according to the practical productivity and theoretical productivity of the spreading machine; and controlling a driving command of the actuating mechanism according to the material level, the control parameters and the practical productivity coefficient. Therefore, according to the spreading machine, and method and device provided by the invention, the problems of relatively large variation of a conveying scraper and a distributing screw and material segregation caused by overhigh speed during the conveying process of asphalt mixed material can be solved.

Description

technical field [0001] The invention relates to the field of paver, in particular to a paver and a method and device for controlling the level of the paver. Background technique [0002] The existing paver is mainly composed of basic vehicle (engine and chassis), feeding equipment (hopper, conveying device and gate), working device (screw paver, vibrator and screed device) and control system, etc. During the working process, the mixed material is unloaded from the dump truck into the hopper of the paver, and conveyed to the paving chamber by the scraper, where it is spread horizontally by the screw paver. With the driving of the machine, the spread mixture is preliminarily compacted by the vibrator, and then the screed behind it is corrected into an appropriate cross-section according to the specified thickness of the paving layer, and then ironed. [0003] The existing paver material level control method is to fix the minimum and maximum control parameters in the control m...
