Description

Technical Field

[0001] The utility model relates to the technical field of agricultural harvesting, in particular to an ear picking and chopping integrated device for a fresh corn harvester. Background Art

[0002] With the rapid development of agricultural mechanization in my country, fresh corn harvesters have also developed rapidly. In China, except for a few areas such as Northeast China and Xinjiang, which use direct harvesting of fresh corn kernels, most other fresh corn harvests are harvested by picking ears. Existing fresh corn picking combine harvesters generally use plate-type picking ears and roller-type picking ears. Both of these picking ear methods are longitudinally inclined picking ears in rows, and both are picking ears directly on fresh corn plants. Such ear picking has the following disadvantages, which seriously restrict the development of fresh corn harvester technology. Disadvantage 1: With the increase of the number of harvesting rows, the ear picking mechanism of existing fresh corn harvester becomes more and more complicated. For example, a four-row fresh corn harvester has four identical ear picking mechanisms. Sometimes, in order to adapt to different row spacings, a multi-channel ear picking cutter is used, and the transmission mechanism becomes more complicated. Disadvantage 2: When picking ears, most of them are harvested in pairs. Since it is very troublesome to turn around in the harvesting operation, the adaptability of existing fresh corn harvesters is poor, which greatly reduces the harvesting efficiency. Disadvantage 3: When picking ears, especially roller-type ear picking, a lot of seeds are knocked off. Since the knocked-off seeds fall directly into the ground and are difficult to recover, it causes great waste. Disadvantage 4: The stem recovery after ear picking is not ideal. After the existing fresh corn plants are picked, the stems are mostly crushed or chopped and returned to the field. A small part of them are chopped or crushed before recycling, but the stem recovery rate is low, generally only about 60%, and the stems recovered after crushing contain more dust impurities, which affects the quality of livestock feed.

[0003] In summary, the existing fresh corn harvester cannot fully recycle the stems of fresh corn plants after picking the ears, the recovery rate is low, and the stems recovered after crushing contain more dust and impurities, which affects the quality of livestock feed. Utility Model Content
