Problems solved by technology

[0004] The main problems of this kind of drive control device: the first is that the layout of the oil cylinder and related control valves and hydraulic pipelines is complex and interlaced, and it is easy to pull each other with foreign objects (branches, wires, etc.) during on-site construction, which affects the safety of the system; The reason is that the number of oil cylinders is large, which increases the manufacturing cost; the third is that the synchronization of the four oil cylinders is poor, which may easily cause "side fall" at the upper end of the folding mechanism; the fourth is that the reliability of each oil cylinder is different, the more the number, the lower the overall reliability. The lower it is, if one of the cylinders fails, it will affect the safety of the entire folding mechanism

Abstract

The invention provides a folding system for a secondary transfer machine of a milling machine. The folding system comprises a folding execution system and a folding hydraulic control system, wherein the folding execution system comprises a fixed arm and a foldable arm hinged with the fixed arm, and further comprises a connection plate, a pull rod and two driving oil cylinders, wherein the connection plate is eudipleural to the middle line of the fixed arm; the lower end of the connection plate is hinged to the lower part of the fixed arm; the upper end of the connection plate is hinged to the upper end of the pull rod; the lower end of the pull rod is hinged to the upper end of the foldable arm; the rear end of each driving oil cylinder is hinged to the upper part of the fixed arm; the front end of the driving oil cylinder is hinged to the connection plate; and the driving oil cylinders drive the foldable arm to be folded through the connection plate and the pull rod. According to the invention, the quantity of oil cylinders and the cost are reduced, and the genealogical reliability is improved. The folding hydraulic control system drives the oil cylinders to lock each other through a hydraulic lock and a flow distributing and collecting valve; and the speeds of the oil cylinders are synchronous through the flow distributing and collecting valve, so as to prevent the transfer machine from inclining laterally. The invention further provides the milling machine comprising the folding system for the secondary transfer machine.

Description

technical field [0001] The invention relates to a folding system, more specifically, to a folding system of a secondary conveyor of a milling machine. The present invention also provides a milling machine comprising the folding system of the secondary conveyor of the milling machine. Background technique [0002] At present, the folding mechanism of the secondary conveyor of the milling machine at home and abroad is mostly a folding drive control device composed of four oil cylinders. One of the specific folding mechanisms is as follows: figure 1 shown.
