AI Technical Summary
The existing ear-picking devices of fresh corn harvesters have problems such as high ear damage rate and poor adaptability, especially in terms of instability with different varieties and ear sizes.
The ear-picking mechanism is a combination of a pair of guide rollers and parallel positioning belts. The stalks are fed in and fall vertically through the stalk-picking belt and positioning belt, so that the ears are supported by the flange under the positioning belt. Combined with the cutting disc blade, the ear stalk is cut off, thus separating the ears from the stalks and avoiding hard pulling and impact.
It effectively reduces ear damage, improves the stability and adaptability of the ear-picking process, and is unaffected by ear size and ear height, achieving low-damage harvesting.

[0002] With the increasing planting area of fresh corn in China, artificial harvesting can achieve no damage, but the labor intensity in the harvesting link is large, and the labor cost is higher and higher. In order to solve the above problems, various fresh corn harvesters have been developed and improved. The existing fresh corn harvesters are all modified from the design scheme of the combination of stem pulling rollers and ear picking plates. During work, the stems are pulled downward by the stem pulling rollers between the two ear picking plates, and the ears with a size larger than the gap between the two ear picking plates are forced to be picked, so that the fresh corn can be picked and harvested. However, there are still some deficiencies. That is, the impact on the ears during the picking process cannot be avoided in principle, the ear damage rate is high, and due to the limitation of the structure of the cutting table picking part, the ear damage problem cannot be fundamentally solved, and the working stability is poor for different fresh corn varieties and ear sizes. Therefore, the existing ear picking device has the problems of high ear damage and poor operation adaptability. SUMMARY

That is, a pair of guide rollers and a positioning belt arranged above the guide rollers are used to replace a traditional stem pulling roller and an ear picking plate combined ear picking mechanism, the weeding belt arranged above the positioning belt feeds the fresh corn stalks backward, the lower part of the stalks falls vertically under the action of the pair of guide rollers, the stalks and the ears are cut off at the same time when the ears are transported to the cutting disc cutter, the ears and the stalks are separated, the whole ear picking process is free of hard pulling and impact, the ear damage can be effectively reduced, the impact on the ears in the ear picking process is avoided in principle, and the working performance is stable. The fresh corn ear picking device has the effects of small ear damage and strong adaptability. BRIEF DESCRIPTION OF DRAWINGS
