Description

Double-layer harvesting table and corn harvester for corn cob and stalk

technical field

The utility model relates to a harvesting table, in particular to a harvesting table used 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 belongs to the technical field of agricultural machinery.

Background technique

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 poor chopping effect and easy blockage; in addition, most of the existing ear harvesters can complete the straw at one time. In the field returning operation, the full amount of straw is returned to the field, and the straw coverage is large, which affects the sowing of the next crop and is easy to breed diseases and insect pests. The innovative research and development of a new type of double-layer harvesting platform and corn harvester can harvest ears and harvest straws at the same time, provide feed for animal husbandry, and at the same time realize the proper amount of straw returning to the field.

The main technical problems existing in my country's existing corn harvesting platform are:

(1) There are two main types of ear picking platforms for corn harvesters in the Chinese market, one is the ear picking roller type, and the other is the ear picking plate type. 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 harvest conditions in the Huanghuai-Hai region, a large amount of broken straw will be generated, which will cause the ear-picking platform to be blocked.

(2) Most of the existing corn harvesting platforms for co-harvesting ears and stems use straw processing devices based on the principle of straw returning machines, which are easy to block, have poor straw chopping effect, and the harvested straw tends to contain soil, which is not conducive to long-term storage.
