Header device and giant rice combine-harvester

Abstract

The invention provides a header device and a giant rice combine-harvester. The header device comprises a header mechanism and a straw returning mechanism which are mounted at the front end of the harvester, and the header mechanism is positioned on the upper portion of the straw returning mechanism. The header mechanism and the straw returning mechanism are placed in the front of the harvester andvertically arranged to form the double-layer header device, rice ears are cut and fed by the aid of the upper header mechanism, stalks of the cut rice ears are crushed and returned by the aid of thelower front straw returning mechanism, upper harvesting and lower crushing operations are finished, and the header device is particularly applicable to harvesting of 'giant rice', effectively adapts to ultrahigh stalk characters of the 'giant rice' and solves the problems that stalks wind a reel, are incompletely cut and cannot be smoothly fed when a common header harvests the 'giant rice', and the common header is poor in adaptability and the like.

Description

technical field [0001] The invention belongs to the field of combine harvesters, and in particular relates to a header device and a giant rice combine harvester. Background technique [0002] The biological characteristics of the newly bred "giant rice" high-yield and high-quality rice varieties are quite different from those of ordinary rice. The existing rice combine harvesters in China can basically meet the quality requirements of ordinary hybrid rice harvesting operations. Higher requirements are placed on the adaptability requirements of the combine harvester. Among them, "Giant Rice Jufeng No. 5" has the most obvious difference. The stem height of the rice plant can reach more than 2.0m, and the highest can reach 2.2m. The fiber and moisture content are high, and there are obvious deficiencies in harvesting "giant rice" with a general-purpose rice-wheat combine harvester: the stalks are wrapped around the reel, the cutting is not clean, and the feeding is not smooth,...

AI Technical Summary

Problems solved by technology

In the present invention, the header mechanism and the straw returning mechanism are placed in front and arranged up and down to form a double-layer header device. The harvesting and feeding of rice ears are completed through the upper layer header mechanism, and the lower layer adopts the front straw returning mechanism to return the harvested straw to the field. The stalks of rice ears are crushed and returned to the field, and the work of harvesting up and down is completed. It is especially suitable for the harvest of "giant rice". When harvesting "giant rice", the stalks are entangled with the reel, the cutting is not clean, and the feeding is not smooth, etc. and poor adaptability
