Abstract

The invention discloses a straddle type supporting ground wheel assembly for lifting adjustment, and relates to a ground wheel assembly. The straddle type supporting ground wheel assembly solves the problem that rapid lifting adjustment cannot be realized since the connecting shaft of an existing ground wheel assembly is easily broken. An outer frame is of an n-shaped structure, slot holes in the vertical direction are symmetrically formed in the two side walls of the outer frame, a nut is fixedly connected onto the top wall of the outer frame, a screw is in threaded connection with the nut, the upper end of the screw is fixedly connected with a hand wheel, the lower end of the screw is arranged between the two side walls of the outer frame and is fixedly connected with the upper end of an adjusting arm assembly, the upper end of the adjusting arm assembly is arranged between the two side walls of the outer frame and is connected with the two slot holes in a sliding mode, supporting arms are mounted on the two sides of the lower end of the adjusting arm assembly in a rotating mode and are positioned on the outer sides of the two side walls of the outer frame, the middle parts of the two supporting arms are connected with the lower ends of the two side walls of the outer frame in the rotating mode, and a ground wheel is connected between the lower ends of the two supporting arms in the rotating mode. The straddle type supporting ground wheel assembly has the advantages of simple structure, low cost and high work efficiency, and is convenient to produce and manufacture.

Description

technical field [0001] The invention relates to a ground wheel assembly, in particular to a ground wheel assembly for straddle support lifting adjustment, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, on the sowing and fertilizing equipment equipped with various mechanical seed meters and fertilizers, the rotational power generated by the contact between the two ground wheels and the ground is used as the power for the mechanical seed meters and fertilizer applicators to complete the sowing and fertilization operations. source. The existing ground wheel is installed on the outside of the support arm. In actual operation, due to the difference in natural conditions, including the difference in the flatness of the field ground, soil moisture content, and soil specific resistance, non-perpendicular contact between the ground wheel and the ground sometimes occurs. In some cases, the connecting shaft between the ground ...
