Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a cleaning device for corn harvesters which is easy to maintain. Background Art

[0002] A corn harvester is an agricultural machine that mechanically completes multiple operations of corn picking, stacking, and returning the stalks to the field at one time when the corn is ripe. The process flow is as follows: the corn is picked by a corn harvester while the corn is growing. Under the action of the ear picking roller and the ear picking plate, the ear stalks are pulled off, and the ears are transported to the peeling machine for peeling, and then collected in the ear box. The corn stalks are squeezed by the stem pulling roller and then enter the straw crusher. After the straw is crushed, it is returned to the field or collected in the corn harvester's straw box for secondary use. Therefore, it is widely applicable.

[0003] When the current corn harvester is in use, due to the different moisture content of corn stalks, the corn stalks with lower moisture content will be broken by the stalk pulling roller. The broken stalks cannot enter the stalk pulling roller in time and are then accumulated in front of the harvesting table, which easily causes congestion and affects the working efficiency of the harvester. For this reason, we propose a corn harvester cleaning device that is easy to maintain. Utility Model Content
