Guide positioning wheel set of piston rod of hydraulic seed cutting machine

Abstract

The invention discloses a guide positioning wheel set of a piston rod of a hydraulic seed cutting machine. The guide positioning wheel set comprises a mounting plate; the mounting plate is provided with a limiting groove, multiple connecting holes and multiple mounting holes; the limiting groove is arranged at the upper part of the mounting plate; the multiple connecting holes are formed in the mounting plate; the limiting groove communicates with the multiple connecting holes; the mounting plate is connected with the hydraulic seed cutting machine through the multiple mounting holes; the upper part of a connecting shaft is mounted in the connecting holes; a positioning hole is formed in the upper part of the connecting shaft, and is corresponding to the limiting groove; a fixed rod is mounted in the limiting groove, and can penetrate through the positioning hole; and a guide limiting wheel is movably mounted at the lower part of the connecting shaft. The guide positioning wheel set is connected with the piston rod of the hydraulic seed cutting machine; and when the piston rod is suffered from the external force effect to generate a torque for rotating tendency, the guide limiting wheel and the connecting shaft can generate reactive force to prevent rotation of the piston rod, so that the stability of the piston rod is improved.

Description

technical field [0001] The invention relates to agricultural equipment, in particular to a guiding and positioning wheel set for a piston rod of a hydraulic seed cutter. Background technique [0002] At present, the main source of the domestic sugar industry is sugar cane, so the sugar cane planting industry is relatively large. However, most of the sugarcane seeds used during sugarcane sowing are cut manually, the degree of mechanization is low, the labor intensity of manual cutting is high, the efficiency is low, and the quality of sugarcane seeds is difficult to guarantee. The use of hydraulic seed cutters can replace manual cane cutting and improve seed cutting efficiency. The hydraulic seed cutter relies on the piston rod of the hydraulic cylinder to push the cutting knife to cut the sugarcane. However, the piston rod is prone to deflection and insufficient rigidity during the movement process, which leads to the deflection of the cutting knife, which is not conducive ...
