Description

Technical Field

[0001] The utility model relates to the technical field of ear picking machinery, and particularly relates to an elastic ear picking device. Background Art

[0002] Corn ear picking is an important link in the corn harvesting process. Generally, an ear picker is used for ear picking. The ear picker includes a roller ear picker and a plate ear picker. The roller ear picker feeds the corn stalk along the axis direction of the ear picking roller. The ear picking roller grabs the stalk and pulls it downwards. When the large end of the ear reaches the surface of the ear picking roller, it is caught and picked by the ear picking claws. The plate ear picker separates the corn ear and the stem pulling roller through two ear picking plates to achieve the picking of the ear.

[0003] However, the current market has put forward higher requirements for the harvesting quality and efficiency of fresh corn. The existing plate ear pickers cannot well meet the market demand, with poor adaptability, many broken stalks, and low efficiency.

[0004] Therefore, in view of the above problems, an elastic ear picking device is proposed to solve the above problems. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model develops an elastic ear picking device, which can reduce the impact on the corn cob during the process of pulling the stem and picking the ear, thereby reducing the damage to the grains. At the same time, it has strong adaptability and high ear picking efficiency.
