[0002] The cotton grabber, also known as the bale grabber, is a machine that grabs cotton fibers from the cotton bale in the cotton opening and cleaning combined unit. It is usually ranked first in the combined machine. There are upper grabbing type, lower grabbing type; trolley reciprocating type, trolley (or cotton bale platform) rotary type; trolley lifting type, platform lifting type, etc. Generally, blades (or saw blades) beaters and ribs are used, and there are also angle nails or spring clamps to grab fibers from the surface of the cotton bale, which are transported to the subsequent machine for further processing by airflow or machinery. Its structure is constantly improving. For example, the upper grabbing type is adopted to achieve multi-bale (40 to 80 bales) cotton mixing; the installation of automatic control devices such as quantitative grabbing is convenient for changing the mixing ratio and improving the accuracy of the mixing ratio.

[0003] However, the existing cotton plucking machine is prone to cause cotton lint to bulge when in use, making the cotton lint cut by the blade larger in volume, which is inconvenient for subsequent processing. In addition, the existing blade is prone to cause cotton lint to be entangled when in use, and is inconvenient to clean. Utility Model Content
