Self-propelled corn grain direct harvesting and straw baling combine harvester

Abstract

The invention provides a self-walking type corn grain direct-harvesting and straw baling combined harvester. On the basis of an existing self-walking type corn and straw recovering and baling combined harvester, dual-roller threshing machines are arrayed on the harvester and matched with a grain conveyer, the grain conveyer is installed below a grain box and is composed of an upper auger, an auger support, a universal coupler, a lower auger, grain conveyer dual chain wheels and an upper auger oil cylinder. A shell of the upper auger and a shell of the lower auger are connected to form a rotating box mechanism. The upper auger and the lower auger in the shells are connected through the universal coupler. The cylinder body end of the upper auger oil cylinder is hinged to the side face of the grain box, and pushing, pulling and rotating are achieved through the upper auger oil cylinder. The harvester mainly achieves corn grain direct harvesting and can recover and bale corn straw, so corn grain direct harvesting and corn straw recovering can be synchronously conducted.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery equipment, and in particular relates to a self-propelled corn grain direct harvesting and straw baling combined harvester. Background technique [0002] Corn is the main food crop planted in the five northern provinces, with an annual planting area of ​​24.5 million hectares 2 . Corn straw is a new renewable resource. Accelerating the comprehensive utilization of straw resources and realizing the commercialization of straw are of great significance for saving energy, reducing air pollution, increasing income, and accelerating the construction of a resource-saving and environment-friendly society. In recent years, under the guidance and support of national policies, straw resource utilization technology has been continuously improved and promoted. Corn straw is used as pellet feed, edible fungus base material, chemical wood products, briquette fuel and commercial power generation, ...

AI Technical Summary

Problems solved by technology

The current corn harvester in the domestic market breaks the corn stalks back to the field and scatter them on the ground. Since most of the fields are not plowed deeply, the broken stalks cannot be degraded in winter, which directly affects the quality of spring sowing operations, making it difficult to sow in the second year and the emergence rate is low. , severe pests and other adverse effects
