Description

Corn Harvester Picking Platform and Corn Harvester

technical field

The invention relates to the technical field of agricultural machinery. Specifically, it is a corn harvester picking platform and a corn harvester.

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. Ear harvesting is basically becoming mature, and grain harvesting has become a hot spot for corn harvesters in this area, and the ear picking platform of corn harvester is one of its important working parts. Due to the high operating efficiency and small ear damage of the plate-type ear picking platform, it has become the first choice for grain harvesters, but there are still problems that the gap between the ear picking plates cannot be adjusted automatically, and the adaptability to different states of corn is poor. For corn with high moisture content during harvesting A lot of broken straw will be produced. Innovative research and development of new ear picking boards is very necessary for low-loss and high-efficiency harvesting of corn.

The main technical problems currently existing in the ear picking boards of corn harvesters in my country are as follows:

(1) The plate-type ear picking platform of the corn harvester in the Chinese market has high ear picking efficiency and little damage to the ear, but for the harvesting conditions in the Huanghuaihai region, a large number of broken straws will be generated, causing the ear picking platform to be blocked.

(2) Although the clearance of the ear-picking plate of the plate-type ear-picking platform of the existing corn harvester can be adjusted manually, the machine needs to be shut down to adjust the clearance of the ear-picking plate, which affects the operation efficiency, so the clearance is basically not adjusted during actual operation.
