Description

A wind pressure conveying device for picking up fallen cotton

Technical Field

The utility model relates to the technical field of agricultural machinery and equipment, in particular to a wind pressure conveying device for picking up fallen cotton.

Background Art

For cotton harvested earlier, some immature bolls will mature after harvest and become the remaining cotton on the cotton plants. For cotton harvested later, due to the long cotton boll opening time, the picking head of the cotton picker will collide with the cotton and the cotton will fall to the ground and become the fallen cotton.

In the existing cotton conveying device, the negative pressure fan is directly installed at the bottom of the cotton conveying pipeline, and the cotton in the seed cleaning box is conveyed to the cotton collecting box by blowing air upwards. The machine works in the cotton field, and the negative pressure fan is likely to blow dust and impurities into the cotton conveying pipeline. The dust and impurities are likely to mix with the cleaned cotton, thereby reducing the quality of the cleaning. After the negative pressure fan stops working, the cotton, impurities, etc. in the cotton conveying pipeline are likely to fall into the negative pressure fan, and the cotton is likely to be entangled in the negative pressure fan. Impurities such as stones are likely to cause damage to the negative pressure fan, thereby reducing its service life.

It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art.
