Combined-type stem-pulling roller used in corn harvester, and corn harvester

Abstract

The invention relates to a combined-type stem-pulling roller used in a corn harvester, and a corn harvester. The combined-type stem-pulling roller comprises roller bodies, guide cones arranged on the front ends of the roller bodies, back support seats used for supporting the roller bodies on the back, and front support seats used for supporting the roller bodies on the front. A plurality of stem-pulling fins extending along the axial direction of the roller bodies are arranged on the peripheries of the roller bodies. The plurality of stem-pulling fins comprise base parts fixedly arranged on the roller bodies and stem-pulling blades extending outwards from the peripheries of the roller bodies. A plurality of arc blade edges are continuously arranged on the edges of the stem-pulling blades. Corn stalk accommodation spaces are formed by the plurality of arc blade edges on the edges of the stem-pulling blades, such that the corn stalks are prevented from being directly cut off by the blade edges formed among the stem-pulling blades. During a corn harvesting process, corn stalks are prevented from breaking too early, and harvested corn ears can be well separated from stalks, such that corn stalks are prevented from entering the inside of the corn harvester.

Description

technical field [0001] The present invention relates to a stemming roller for a corn harvester, and also to a corn harvester comprising such a stemming roller. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The ear picking device is the core component of the corn harvester, and its main function is to separate the ear from the stalk. At present, there are roughly four kinds of ear picking devices commonly used in China, namely horizontal roller type ear picking device, vertical roller type ear picking device, clamping chain horizontal ear picking device and ear picking plate and stem roller combined ear picking device. Although these ear picking devices can meet the technical requirements, there are deficiencies in practical application. Although the vertical roller type has a small loss in harvesting, the s...

AI Technical Summary

Problems solved by technology

[0007] For the corn harvester in the prior art, the stalk rollers of the corn harvester tend to break the stem and tip of the corn during the harvesting process, and thus cause a large amount of impurities to enter the main machine, resulting in more failures of the harvester, increased fuel consumption, and reduced efficiency. Problem, the present invention proposes a stemming roller for a corn harvester that solves the above problems, and the specific structure is as follows
