Paver and ironing device thereof

Abstract

The invention discloses an ironing device of a paver. The ironing device comprises at least two segments of ironing plates, wherein an electric heating device is mounted on a base plate of each segment of ironing plate; each electric heating device comprises an electric heating rod and a control box; and each control box comprises a regulating and detecting unit for detecting open circuit, short circuit and electric leakage of the heating device and regulating the voltage of the electric heating rod or cutting off voltage output. Furthermore, the invention also provides the paver. By independently regulating the voltage of the electric heating rod on each segment of ironing plate, the temperature of the ironing plates can be kept same. In addition, the heating of other segments of ironing plates is not affected even the electric heating rod on a certain segment of ironing plate has a fault, and simultaneously the fault is convenient to eliminate.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a paver screed device and a paver. Background technique [0002] Asphalt paver is suitable for paving the base and surface course of various materials; it is a special machine suitable for paving asphalt mixture roads, RCC base layer materials, stabilized soil materials and graded gravel and other road construction materials. Indispensable key equipment for highways and high-grade highways. [0003] The ironing device is the main working device of the paver, and its function is to compact and iron the hot mixture delivered to the trough. The screed device of a general paver is composed of a traction arm (boom), a vibrating beam, a screed, a thickness adjustment mechanism, and a camber adjustment mechanism. The screed and the vibrating beam are arranged at the rear of the screw distributor, the front end is provided with a scraper, and the two ends of the screed are equipped...

AI Technical Summary

Problems solved by technology

The electric heating system has the following disadvantages: when the electric heating rod on a certain section of the screed fails, such as a short circuit or leakage, the electric heating of the entire screed will be cut off; the electric heating rods on the entire screed apply the same electric heating voltage , the temperature of the screed in the middle will rise the fastest, while the temperature of the outermost screed will rise the slowest, resulting in inconsistencies in the lateral temperature of the entire screed, and temperature segregation during paving, which will affect the paving quality; the electric heating voltage is only There are two states of open or closed, so that the temperature of the screed device fluctuates greatly; since there are at most 36 electric heating rods in the entire screed, when a fault occurs, it will take a long time to troubleshoot and it will be difficult
