Abstract

The invention discloses a pose pre-adjusting coupled bionic corn ear picking device which comprises a rack, a gearbox, a stem pulling roller, a driving chain wheel, a driven chain wheel, a plant pulling chain, a plant pulling chain tensioning device, a fixed ear picking wheel combination and a movable ear picking wheel combination, wherein the fixed ear picking wheel combination consists of a fixed ear picking wheel frame, a fixed ear picking wheel shaft and a fixed ear picking wheel; and the movable ear picking wheel assembly is composed of a movable ear picking wheel, a movable ear picking wheel shaft, a movable ear picking wheel support, a plummer block, a middle shaft, a spring seat shaft, a spring seat and a reset spring. The pose pre-adjusting coupled bionic corn ear picking device can change the pose of corn ears at the moment of ear picking of a header of a corn harvester, so that the ears deflect at an angle of 55 degrees or more to change the breaking mode of ear stalks and reduce the breaking force of the ear stalks; after ear picking is completed, the ear picking wheels restore to the original positions so as to enlarge the ear picking gap and prevent blockage.

Description

technical field [0001] The invention relates to a corn harvester, in particular to a corn ear picking device that changes the corn ear posture at the moment of ear picking to cause angular deflection, thereby changing the fracture characteristics of the ear stalk and reducing the breaking force of the ear stalk. The invention belongs to agricultural machinery field. Background technique [0002] Ear picking is the primary technical link of corn mechanized harvesting. When the traditional ear picking device is working, the corn cob stalk is forcibly broken by the stem pulling roller, so that the ear is picked off. Since the cob stalk of corn has a large number of fiber bundles and has a high structural strength, the breaking force of the cob stalk can reach hundreds of N or even thousands of N. On the one hand, this method of picking ears causes a large power consumption of the header, and on the other hand, it is easy to cause structural failure due to the large impact loa...
