Abstract

The invention discloses a double-traction device of an articulated tractor and relates to the technical field of farm machinery. The double-traction device comprises a front frame, a rear frame and traction rods. A traction seat is mounted on the front frame. Two traction rods arranged up and down are hinged to the traction seat by means of traction pins. At least one connecting plate is mounted on the rear frame, and the two traction rods run through the connecting plate. A limiting block pin is mounted at the rear end of each traction rod. Compared with the prior art, the double-traction device of an articulated tractor has the following advantages that up-and-down sway generated by the traction connection part on load is greatly reduced; the connection parts at two ends of the traction rods are avoided from breakage and deformation, and the stability of connection between the front frame and the rear frame is improved; and in case of emergency braking or turning, independent rollover of the front part or independent rollover of the rear part of the tractor is avoided with high safety.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a double traction device of a folding tractor. Background technique [0002] The bent tractor is a self-propelled power machine used to pull and drive working machinery to complete various mobile operations. At present, the traction device of the folding tractor includes a front frame and a rear frame respectively installed on the front axle and the rear axle. The two ends are respectively hinged with the fifth wheel and the rear vehicle frame through pin shafts. The traction device of this folding tractor has the following disadvantages during use: the carriage will swing during driving, especially when the traction joint is loaded, the traction joint often swings up and down, causing the joints at the two ends of the drawbar to be easily broken and deformed ; The stability of the connection between the front frame and the rear frame is poor, and it is easy to c...
