Self-feedback floating scraping system of pavement milling machine

Abstract

The invention belongs to the field of pavement engineering machinery, and relates to a self-feedback floating scraping system of a pavement milling machine. The self-feedback floating scraping system comprises a scraping plate and a control system, wherein the scraping plate is arranged on the lower part of a turning body of the pavement milling machine and can lift by being driven by a scraping plate oil cylinder; the control system is used for controlling the lifting of the scraping plate, and comprises a pressure sensor which is arranged on the scraping plate and can detect ground pressure of the scraping plate; the detection signal output end of the pressure sensor is connected to a CPU (Central Processing Unit) capable of processing detection data; and the control instruction output end of the CPU is connected to a scraping plate valve group capable of controlling the action of the scraping plate oil cylinder. The self-feedback floating scraping system disclosed by the invention can keep the appropriate ground pressure all the time for milling in a pulling and scraping operation process by detecting and regulating the ground pressure of the scraping plate in real time, thereby being suitable for the change of pavements with different terrains and improving the construction effect and efficiency.

Description

technical field [0001] The invention belongs to road surface engineering machinery and relates to a self-feedback floating scraping system of a road surface milling machine. Background technique [0002] The working process of the road milling machine needs to scrape the milled road surface to achieve the purpose of cleaning the road surface and collecting waste. Existing milling machines generally adopt a simple pulling and scraping operation form, that is, a set of scraping device is installed at the rear of the milling drum, and the scraping device is naturally grounded, and the grounding pressure is constant. This method can only simply realize the scraping function, but does not have any adjustment adaptability in the complex working conditions of the milling machine. As a result, on the one hand, the cleanliness of the scraped material cannot be controlled, and on the other hand, it may cause excessive scraping of the ground, causing excessive forward resistance in th...

This method can only simply realize the scraping function, but there is no adjustment and adaptability in the complex working conditions of the milling machine

As a result, on the one hand, the cleanliness of the scraped material cannot be controlled, and on the other hand, it may cause excessive scraping of the ground, causing excessive forward resistance in the milling work, which is not economical, environmentally friendly, and reduces work efficiency. Even affect the work, damage the machine
