Abstract

The invention discloses a straddle-type support ground wheel transmission system of a sowing-fertilizing machine tool, and relates to a ground wheel transmission system. The invention aims at solving the problems that the connection shaft of the existing ground wheel transmission system is liable to break, and the transmission of a gear shaft cannot be realized. The transmission system comprises two ground wheel assemblies, two telescopic shaft transmission assemblies, and a middle shaft transmission assembly of the sowing-fertilizing machine tool, wherein the two ground wheel assemblies are arranged at the left and right in parallel; each ground wheel assembly comprises two support arms, and a ground wheel is arranged between the lower ends of the two support arms; the ground wheels of the two ground wheel assemblies are connected through a ground wheel connection shaft, the power source generated by the ground wheels is transferred onto the middle shaft transmission assembly of the sowing-fertilizing machine tool through the ground wheel connection shaft, a first bevel gear, telescopic shafts, a second bevel gear and a third bevel gear. The transmission system disclosed by the invention has the advantages of simple structure, convenience in production and manufacturing, low cost and high working efficiency.

Description

technical field [0001] The invention relates to a ground wheel transmission system, in particular to a straddle-supported ground wheel transmission system for sowing and fertilizing equipment, and 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 ...
