Description

Technical Field

[0001] The utility model relates to the technical field of raw cotton analyzing machines, in particular to a collecting box connected to the raw cotton analyzing machine. Background Art

[0002] At present, the common intelligent rapid raw cotton impurity analyzer adopts the principle of mechanical aerodynamics. After the raw cotton is weighed, the external bellows generate a suction airflow in the air flow channel inside the analyzer. The licker-in roller inside the analyzer rotates to comb the raw cotton, separating the cotton fibers from the impurities attached to them. The lighter cotton fibers are sucked into the cotton collection box on the rear side, while the heavier impurities fall into the impurity collection box below. The impurities are then weighed by the weighing sensor at the bottom of the impurity collection box, and the mass percentage of the impurities is calculated.

[0003] The analyzed cotton fibers and impurities will be sucked and collected through a collection box. The existing collection box is equipped with a cotton fiber collection chamber and an impurity collection chamber. When the fan is sucking, a filter is used for filtering. However, after a long period of filtration, the filter will be blocked by cotton fibers or impurities, requiring regular manual maintenance, which is more troublesome. Utility Model Content
