Paver with double material level sensors, and material level height control method

Abstract

The invention discloses a paver with double material level sensors, and a material level height control method. The paver is provided with a material distributing device and a telescopic screed plate,the telescopic screed plate comprises a basic section screed plate and a telescopic section screed plate arranged on the rear side of the basic section screed plate, and the telescopic section screedplate can transversely move relative to the basic section screed plate; and the paver further comprises a first material level sensor, a second material level sensor and a material level controller,the first material level sensor, the second material level sensor and the material distributing device are all in signal connection with the material level controller, the first material level sensoris used for detecting first material level height information in the trough, the second material level sensor is used for detecting second material level height information in a material containing cavity, and the material level controller is used for controlling the rotating speed of the material distributing device and / or starting and stopping of the material distributing device. The material level height between the telescopic section screed plate and a front baffle can be automatically adjusted, the labor intensity of operators is relieved, and the paving quality is improved.

Description

Technical field[0001]The invention relates to the technical field of pavers, in particular to a paver with double material level sensors and a material level height control method.Background technique[0002]The paver usually includes a walking device, a hopper, a conveying device, a distributing device, a screed, etc. The walking device is used to drive the paver forward, the hopper is used to receive and store paving materials, and the conveying device is used to move the hopper The paving material is conveyed to the back of the paver and before the screed. The distribution device is used to convey the paving material from the conveying device to the entire paving width. The screed is located behind the paver and is used to transfer the paving material. Initially compacted, smoothed and finally formed. Screeds usually include mechanical screeds and telescopic screeds. Mechanical screeds use fasteners to assemble lengthened sections of different widths to achieve different working wi...
