Technical Field

The utility model relates to the field of agricultural machinery, concretely relates to pluck ear of grain and draw stem roller, pluck ear of grain frame and maize picker.

Background

The ear-picking stalk-pulling roller is a device for separating ears and stalks in a corn harvester, and two ear-picking stalk-pulling rollers are combined into a group and are arranged on a fixed frame. When the corn harvester works, the corn crops are cut by the cutter and are conveyed backwards by the reel conveying chain, the stalks are pulled backwards through the space between the two ear-picking stalk-pulling rollers, and the ears are blocked by the ear-picking stalk-pulling rollers, separated from the stalks and dropped.

The existing ear-picking stalk-pulling roller is usually in an integrated fixed connection structure, and when the ear-picking roller or the stalk-pulling roller is damaged, the whole ear-picking stalk-pulling roller needs to be replaced, so that the maintenance cost is higher. And the ear-picking stalk-pulling roller is easy to wind weeds and corn leaves, and some corn harvesters can install impurity removal blades beside the ear-picking stalk-pulling roller, but the installation structure is more complicated, so that the weeds or the piled broken objects are easily hung at the connection positions of all parts, and the maintenance is not convenient.
