Single-oil-cylinder folding mechanism for milling machine conveying frame

Abstract

The invention discloses a single-oil-cylinder folding mechanism for a milling machine conveying frame, which is characterized by comprising a left steel frame and a right frame mutually hinged with each other, wherein the left steel frame is hinged with one hinge point of a triangular support having three hinge points, and the other two hinge points of the triangular support are hinged with a hinge oil cylinder and the right frame; one end of the oil cylinder is hinged with one hinge point of the triangular support, and the other end of the oil cylinder is hinged with the left steel frame; and the hinged part of the right steel frame and the triangular support is provided with a hinge structure in which a chute pin is clamped in a chute and moves along the chute. The single-oil-cylinder folding mechanism is simple in structure, capable of realizing a folding function due to adoption of the single oil cylinder, low in construction cost, and convenient to maintain, and the quality reliability can be improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a single oil cylinder folding mechanism for a milling machine feeding frame. Background technique [0002] The feeding frame of the milling machine is long, and it needs to be unfolded to transport the milling scraps to the delivery truck during work, and it needs to be folded after the work is finished to save the space occupied by the whole machine. figure 1 The three-cylinder folding mechanism shown in the figure can realize the above functions, but the three-cylinder folding mechanism has high cost, complex structure and difficult installation. Contents of the invention [0003] The purpose of the present invention is to provide a folding mechanism with a simple structure, a single oil cylinder can be used to realize the folding function, low manufacturing cost, convenient maintenance, and improved reliability of the product. [0004] The solution of the present inven...
