Silage maize harvester, and cutting tool and cutting cutterhead for silage maize harvester

Abstract

The invention discloses a silage maize harvester, and a cutting tool and a cutting cutterhead for the silage maize harvester. The cutting tool comprises a cutting tool body in the shape of a fan ring.A toothed structure is arranged at the working end of the outer edge of the fan ring of the cutting tool body. A blocky cutting blade is arranged on the upper surface of the tip of each tooth of thetoothed structure, and the hardness of each cutting blade is greater than that of the cutting tool body to achieve automatic blade sharpening of the cutting tool during operation. During long-term operation of the cutting tool, the cutting tool body wears rapidly, the cutting blades wear slowly to naturally form cutting blades of cutting portions, and accordingly, automatic blade sharpening is achieved; the wear resistance and sharpness durability of the cutting tool are improved, and operation power consumption of the silage maize harvester is reduced.

Description

technical field [0001] The disclosure relates to the technical field of silage harvesting machines, in particular to a cutting tool for a silage machine, a cutting disc and a silage machine. Background technique [0002] With the implementation of my country's grain-to-forage policy, the pasture industry will have a great development. Silage corn is the key direction of grain-to-forage reform, and it is expected to reach 25 million mu in 2020. Although my country's silage equipment has developed greatly in recent years, it still cannot meet the needs of the continuous expansion of the forage industry. Green fodder harvesting is an operation item that requires high timeliness of operation. The quality of the cutting tool directly affects the operation stability, harvesting efficiency and energy consumption of the silage machine. [0003] Existing cutting knives all adopt a disc-shaped structure with a cutting knife at the end, and the material is generally manganese steel or...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this disclosure is to overcome the shortcomings of the above-mentioned prior art, and provide a cutting tool for a silage machine, a cutting disc, and a silage machine; the cutting tool can effectively solve the problem of poor wear resistance, high cost, and difficult processing of existing silage machine cutting tools. The problem of large and sharp durability
