High-stalk crop harvesting header device and harvester

Abstract

The invention relates to a high-stalk crop harvesting header device and a harvester. The high-stalk crop harvesting header device comprises a header body and a feeding auger, wherein the feeding augeris rotatably mounted at the rear end of the header body, the high-stalk crop harvesting header device further comprises a pushing device, the pushing device is rotatably connected with the rear end of the header body, and is located above the feeding auger. The header device has the beneficial effects that the pushing device is arranged above the feeding auger, the condition that high-stalk cropsare in overlapped connection to the rear wall of the header body can be avoided, the crops can be conveyed downwards to the feeding auger, the problems that when the header harvests the high-stalk crops, stem ears are in overlapped connection to the rear wall of the header and cannot be collected, and ear losses are caused, are solved, and therefore, the harvesting efficiency is improved; and theharvesting loss of the header is effectively reduced. The harvester is good in performance, reasonable in structure, convenient to replace, high in adaptability and high in reliability when being used for harvesting the high-stalk crops, is particularly suitable for high-quality and high-efficiency harvesting of sorghum, quinoa, millet and other crops, and fills the market blank.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a high-stem crop harvesting header device and a harvester. Background technique [0002] In recent years, the market for miscellaneous grain harvesters has gradually expanded. The planting area of ​​sorghum main production areas in my country is more than 13 million mu, mainly distributed in Inner Mongolia, Shanxi, Shandong, Northeast and other regions. The machine harvest rate is about 60%. The planting area of ​​quinoa main production areas More than 2 million mu, mainly distributed in Gansu area, with a machine yield rate of about 15%. At present, the main harvesting methods of sorghum and quinoa in my country include manual harvesting and grain combine harvesting. For mechanical harvesting of sorghum and quinoa, most domestic enterprises are in the experimental stage. Due to the low efficiency of manual harvesting, high cost, greater influence by the weather, and the in...

AI Technical Summary

Problems solved by technology

During its flow, due to the planting characteristics of sorghum, millet, and quinoa: high plant height, large ear heads, low stubble cutting, and many lodgings, the reel reel has a poor reeling support effect, and the loss of hitting the ear heads is large. The length of the forward extension of the bottom plate of the header is insufficient, the ears of the header are seriously dropped, and manual picking is time-consuming and laborious and the loss is large

[0004] The structure of the current header at home and abroad can not meet the current situation of harvesting high-stalk miscellaneous grain crops, the loss rate of the header is relatively large, and the problems of poor feeding have not been solved.

With regard to sorghum, quinoa and other miscellaneous grain harvesting headers, most manufacturers are in the experimental stage, and some users directly increase and lengthen the wheat harvesting headers to restructure grain harvesting. The miscellaneous grain harvesting headers currently being developed in the experimental stage are still not comparable Good for tall stalk crop harvesting

The shortcomings of the prior art are mainly manifested in the following aspects: ① Poor adaptability to harvesting headers for crops such as high-stalk sorghum and quinoa; ② Large loss of headers; ③ Low operating efficiency
