Corn ear and stem harvesting double-deck harvest table and a corn harvester

Abstract

The invention provides a corn ear and stem harvesting double-deck harvest table and a corn harvester. Operations such as corn ear picking and straw chopping and recycling can be completed at a time, stem cutting-conveying-chopping-throwing operation procedures can be completed on a bottom harvest table body while ear picking is completed on a top harvest table body, the harvest table operation efficiency is improved, high quality feed can be provided for animal husbandry, and meanwhile appropriate returning of straw can be achieved. The harvest table comprises the top harvest table body and the bottom harvest table body; the top harvest table body comprises an ear picking rack, a divider and an ear picking device, the divider is arranged at the front end of the upper portion of the ear picking rack, the ear picking device comprises an ear picking roller, an ear conveyor and an ear picking transmission case which are all arranged on the ear picking rack, the ear picking roller is connected with the ear picking transmission case, and the ear conveyor is located at the back of the ear picking transmission case; the bottom harvest table body is located under the top harvest table body and comprises a stem cutting device, a stem conveying device, a steam chopping device and a stem throwing device.

Description

technical field [0001] The invention relates to a harvesting table, in particular to a harvesting table for a corn harvester and a corn harvester, which can complete corn ear picking, straw chopping, recycling and other operating functions at one time, and belong to the technical field of agricultural machinery. Background technique [0002] Corn is the largest food crop in my country. The summer sown corn in China is mainly concentrated in the Huanghuaihai region, which is the most concentrated corn production area in my country. The sown area is about 160 million mu, accounting for more than 30% of the total corn area in the country. This area adopts the planting mode of two crops a year, and large-scale contiguous planting, which is relatively easy to realize mechanized combined harvesting operations. When the corn is harvested in this area, the stalk has a high moisture content and can be used as feed. The existing ear and stem combined harvesters have problems such as p...

AI Technical Summary

Problems solved by technology

Among them, the roller-type ear-picking can adapt to harvesting under the conditions of high moisture content of corn in the Huang-Huai-Hai region, with less broken straw and the ability to actively transport straw, but the ear-picking hook is easy to cause ear drop and damage

The plate-type ear picking platform has little damage to the ear, but for the harvesting conditions in the Huanghuaihai region, a large amount of broken straw will be generated, which will cause the ear picking platform to be blocked

[0005] (2) Most of the existing corn harvesting platforms for ear and stem harvesting adopt the straw processing device based on the principle of the straw returning machine, which is easy to block, the effect of straw chopping is poor, and the harvested straw is easy to contain soil, which is not conducive to long-term storage
