Cotton picking machine

Abstract

The present invention relates to a cotton picker. It includes the following several portions: electric picking head, conveying hose, negative pressure fan, cotton storage barrel and DC power supply. Said invention also provides their connection mode and the concrete working principle of said cotton picker.

Description

technical field [0001] The present invention relates to agricultural machinery, and more particularly, to a cotton harvester. Background technique [0002] In my country, large, medium and small cotton pickers have all appeared, but they have not been practically popularized and used. Although foreign large-scale cotton pickers have high cotton picking efficiency, there are still a series of problems in domestic use. First of all, it has certain requirements for the cotton it picks. It requires that the cotton in the same field mature at the same time, grow to the same height, and drop leaves at the same time. Obviously, my country's current cotton seeds and planting levels are not up to this requirement. In addition, the cotton picked by this large cotton picker has a high trash rate, and the auger-like harvesting device at the front end will cut the cotton wool short, thereby reducing the quality of the harvested cotton and affecting the economic benefits of the cotton f...

AI Technical Summary

Problems solved by technology

Obviously, my country's current cotton seeds and planting levels are not up to this requirement

In addition, the cotton picked by this large cotton picker has a high trash rate, and the auger-like harvesting device at the front will cut the cotton wool short, thereby reducing the quality of the harvested cotton and affecting the economic benefits of cotton farmers

Furthermore, the cost of this large cotton picker is high, and it is not suitable for the operation of small cotton fields.

[0003] There has been a medium-sized cotton picker in the market that uses a suction head to absorb the cotton bolls in the bolls. For bolls with different maturity levels, the suction is difficult to adjust. If the suction is too high, impurities such as cotton leaves will be sucked together, and the impurity content of the cotton bolls will increase. high, degraded quality

If the suction force is too small, the cotton wool in the center of the boll can only be sucked in, and the cotton wool sticking to the boll cannot be sucked, and the recovery rate is low, resulting in the loss of cotton wool

[0004] Although various small cotton picking machines can reduce physical labor to a certain extent, the harvested cotton contains impurities, especially because the machine is very close to the human body during picking, which makes the cotton wool easily stick to human hair and reduces the quality of the harvested cotton The problem has not been well resolved
