Abstract

The invention belongs to the technical field of silage harvester research, and relates to a profiling stubble breaking device and method of a silage corn harvester. The profiling stubble breaking device is fixedly connected to the lower side of the rear end of a header and used for beating and breaking stubbles left on the earth surface after harvesting through the header. The profiling stubble breaking device comprises a supporting machine frame, an air pump and a plurality of stubble breaking device single bodies, and the stubble breaking device single bodies are arranged side by side at certain intervals. The stubble breaking device single bodies comprise swing devices, protective cover shells, stubble cutting knives and motors According to the profiling stubble breaking device, harvesting and stubble breaking synchronous operation can be achieved, the single stubble breaking device bodies can perform profiling independently and do not interfere with one another, the functionality of the silage corn harvester is improved, the number of times that an operation machine enters the ground is reduced, and the purpose of better protecting cultivated land is achieved.

Description

technical field [0001] The invention belongs to the technical field of silage corn machinery, and more specifically relates to a profiling stubble breaking device and method for a silage corn harvester. Background technique [0002] With the expansion and promotion of silage corn planting area and no-tillage sowing technology in my country, the ecological conditions are improving day by day, and the problems of diseases and insect pests are increasing year by year, mainly corn borer. The corn borer is a borer-type pest, and the typical symptoms caused by it are: after the core leaf is bored through, moth-eaten holes appear inside the stalk, resulting in the destruction of the internal structure, reducing the wind resistance of the stalk, and limiting the grain growth of the affected plant ; During the wintering period, the larvae mostly parasitize on the root or the stem near the soil end, and the stubble of the harvested stem and the surface stem provide good conditions for ...
