Problems solved by technology

[0003] The present invention has designed and developed a corn ear picking device based on bio-profiling. The purpose of the invention is to reduce the loss of corn kernels in the ear picking process and reduce the need for the stem rollers to obtain sufficient stem pulling force during the stem pulling process. The problem with damage to corn stalks

Embodiment Construction

[0031] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0032] The invention adopts the ear-picking board-stem-pulling roller combined ear-picking method, wherein the ear-picking board is designed to imitate the changing arc of the root of the corn ear by applying the bionic middle-profile principle, and the surface of the stem-pulling roller is designed to imitate the shape of the corn stalk, specifically: A corn ear picking device based on bio-profiling, comprising: a concave groove imitating the changing arc of the root of the corn ear is designed on the edge of the ear picking plate, wherein the arc equation is y=0.1026x 3 -0.6749x 2 +1.7436x+0.0745; the ear-picking plate is set above the stem-pulling roller, the ear-picking plate is installed in parallel with the stem-pulling roller, and has a certain interval with the stem-pul...

Abstract

The invention discloses a corn ear plucking device based on biological profile modeling. The corn ear plucking device comprises ear plucking plates and stem pulling rollers, wherein each ear plucking plate comprises a flat plate part and a concave surface groove, the ear plucking plates are symmetrically arranged, the concave surface grooves are oppositely formed, and the flat plate parts are not in contact with each other; the stem pulling rollers are symmetrically arranged, are mounted below the ear plucking plates, and can rotate relatively towards the inner side; the curvilinear equation of the cross section curved sections of the concave surface grooves is as shown in the description.

Description

technical field [0001] The invention relates to the field of biomimetic agricultural machinery, in particular to a corn ear picking device based on biomimetic shape. Background technique [0002] The corn ear picking device is the core component of the corn harvesting machine, and the performance of the corn picking device will directly determine the working performance of the corn harvesting machine. Most of the ear picking devices configured in the corn harvesting machinery commonly used today are the ear picking roller type, the ear picking plate-stem pulling roller combination type, and the ear picking plate-stem pulling roller combination type is widely used because of its wide adaptability. on existing corn harvesting machinery. The ear-picking plate-pulling-roller combined ear-picking device has outstanding advantages in terms of adaptability, but it has some advantages in reducing ear crushing, grain damage, grain loss, and reducing ear impurities caused by corn sta...
