Problems solved by technology

For the first method, due to the continuous contact between the ear and the picking roller with spiral ribs, it will inevitably cause the ear to be gnawed and the grains to fall off; During the process, the ear is subjected to a strong impact force, which can easily lead to the breakage of the stalk, resulting in the blockage of the ear picking platform, which affects the working reliability of the corn harvester
For this reason, many scholars have carried out research on improving its structure, mainly using bionic methods or changing the helical rib structure on the picking roller to reduce the damage of the picking roller to the ear, but it does not change the effect of pulling and picking the ear. Therefore, it is of great practical significance to study new principles and new methods to realize the separation of ears and stalks to improve the harvesting efficiency of ears and reduce the damage and shedding of ears.

Abstract

The invention discloses a vibration type corn ear picking roller which comprises a long ear picking roller body, a short ear picking roller body, guide cones, adjustable bearing pedestals, strong tensile sections and the like. The section of the long ear picking roller body and the section of the short ear picking roller body are each of an elliptical structure. The long axis of the cross sectionof the long ear picking roller body and the short axis of the cross section of the short ear picking roller body are matched. The long ear picking roller body and the short ear picking roller body areconnected with the guide cones through connecting shafts. The connecting shafts are sleeved with the adjustable bearing pedestals which closely abut against the long ear picking roller body and the short ear picking roller body. The strong tensile sections are installed at the rear end of the long ear picking roller body and the rear end of the short ear picking roller body. Spiral protruding edges are welded to the long ear picking roller body and the short ear picking roller body respectively. The vibration type corn ear picking roller has the advantages of being simple in structure, low inpower consumption, free of seed loss or seed falling in the work process, and capable of realizing low-loss and high-efficiency ear picking.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a vibration-exciting corn ear picking roller. Background technique [0002] As the last link to realize the mechanization of corn production, the corn harvester has a great influence on the harvesting efficiency and harvesting quality of corn. At present, the principle of corn harvesting mainly adopts two operation methods, one is to separate the ear from the stalk through a pair of cylindrical ear picking rollers with spiral convex ribs to force the corn stalk to be separated, and the other is to separate the ear from the stalk by a pair of pulling the stalk. The cooperation of the roller and the picking plate realizes the separation of the ear and the stalk. There is no difference in essence between the two methods, that is, by applying a pulling force to the stalk, when the pulling force is greater than the stalk and the ear or the stalk and the stalk When the ...
