Paver material splitting system for increasing material splitting material level stability and control method

Abstract

The invention discloses a paver material splitting system for increasing material splitting material level stability and a control method. The control method comprises the following steps: step one, computing a needed material amount delta according to the walking speed V, the paving width B and the paving thickness H of a paver; step two, computing the material splitting rotating speed X1 according to the needed material amount delta as well as the radius R and the thread pitch P of a material splitting blade, and using the material splitting rotating speed X1 as a control reference signal, wherein X1 is equal to delta / (pi*R*R*P); step three, measuring the material level by material level sensors which are arranged at two ends of a material splitting groove, sending the material level toa controller, and generating a control signal X2 according to measured actual material level values of the two ends of the material splitting groove by the controller; step four, outputting a final control signal X to a material splitting hydraulic pump for controlling the material splitting rotating speed of a material splitting motor according to preset control weights K1 and K2, wherein X is equal to K1*X1+K2*X2, K1 is larger than K2 and the sum of K1 and K2 is equal to 1. According to the control method disclosed by the invention, the problems of non-uniform material level and too fast material splitting rotating speed within a length range of a whole material groove can be well solved, and the uniformity of flatness and compactness of a paved pavement can be increased.

Description

technical field [0001] The invention relates to a paver material distribution system and a control method for improving the stability of the material distribution level. Background technique [0002] At present, the paver measures the material level by setting a material level sensor at the end of the trough, and uses the measured value as a material level detection signal within the entire length of the trough to control the material level of the entire trough. figure 1 It is a structural schematic diagram of the material distribution system of the paver currently designed, in which, 1 is the material level sensor at the end of the material distribution chute, and the left and right two are symmetrically arranged, 2 is the front baffle of the material distribution chute, 3 is the screed, the screed Together with the front baffle of the material distribution tank, it forms the material distribution tank. 4 is the material distribution spiral blade, which is connected with th...
