Self-adaptable spring stern door of asphalt pavement milling machine

Abstract

The invention discloses a self-adaptable spring stern door of an asphalt pavement milling machine. The self-adaptable spring stern door comprises a rack, a door plate, a guide groove, a spring and a sliding shaft, wherein the guide groove is fixedly formed in the lower side of one end of the rack; the door plate is arranged in the guide groove in a sliding manner; a guide sleeve is fixedly arranged on the upper side of the other end of the rack; the sliding shaft is arranged in the guide sleeve in a sliding manner; a limiting baffle block is fixedly arranged at the upper end of the sliding shaft; the spring sleeves the sliding shaft; the lower end of the sliding shaft is fixedly connected with one end of a fixed connection plate; and the other end of the fixed connection plate is fixedly connected with the door plate. The self-adaptable spring stern door has the characteristics of reasonable design, relatively low cost, good economical efficiency, constant stern door grounding pressure and high control reliability, does not relate to hydraulic and electric control systems, and can adapt within a small range; the operation efficiency and quality of the pavement milling machine can be improved; and the recovery rate of milled materials is improved.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a spring self-adaptive tailgate of an asphalt road milling machine. Background technique [0002] At present, with the development of my country's economy and the enhancement of comprehensive national strength, the trend of urbanization of townships, small and medium-sized cities, and gardening of large and medium-sized cities is becoming more and more obvious, and there are more and more urban road reconstruction and expansion projects; now many provinces in mainland China For example, the highway construction in Zhejiang, Jiangsu, Henan and other places has transitioned from "building" to "maintenance"; the "reproduction" of expressways is becoming more and more common. In the construction of expressways, in order to meet the needs of ecological construction, often The milled asphalt will be put into processing and use. The road milling machine is one o...

[0002] At present, with the development of our country's economy and the enhancement of comprehensive national strength, the trend of urbanization of towns, small and medium-sized cities, and gardening of large and medium-sized cities is becoming more and more obvious, and there are more and more urban road reconstruction and expansion projects; now many provinces in mainland China For example, the highway construction in Zhejiang, Jiangsu, Henan and other places has transitioned from "building" to "maintenance"; the "reproduction" of expressways is becoming more and more common. In the construction of expressways, in order to meet the needs of ecological construction, often The milled asphalt will be put into processing and use. The road milling machine is one of the indispensable equipment for road mechanized maintenance, but the tailgate of the road milling machine exists when scraping forward: the recovery rate of milling material is low, and the milling Problems such as uneven road groove and high scraping resistance
