The impurity removing device is provided with more than ten pairs of impurity removing wheels, because about one ton of cotton stalks are treated by the cotton stalk skin-core separator, about seven hundred kilograms of broken stalk cores are removed from the cotton stalk skins every hour, although the broken stalk cores are separated from the cotton stalk skins after passing through the separator, the broken stalk cores are completely separated from the cotton stalk skins and fall into a conveying belt below a truck belly funnel to be conveyed away, a larger space is needed for transferring, and partial broken stalk cores are reflowed and attached to the cotton stalk skins by airflow generated by high-speed operation of the machine in a semi-closed state.
Each pair of the impurity removing wheels increases the depth of the upper and lower cross (overlapping) in turn by 0.5-1mm along the advancing direction of the cotton stalk barks, and correspondingly increases the surface linear velocity of the impurity removing wheels in turn, which is an effective measure for gradually increasing the striking force degree of the cotton stalk barks, can timely, fully and smoothly remove impurities such as broken stalk cores and the like, transfer, straighten and straighten the cotton stalk barks, and does not damage the cotton stalk barks.
The further technical scheme of the invention is as follows: the diameter of the cold-drawn round steel is not more than 3mm, and the thickness of the cold-rolled steel sheet is 2-4 mm.
Furthermore, the impurity removing device is arranged close to the guide wheel of the front reversing device, and cold-rolled steel sheets are uniformly distributed on the surfaces of the first pair of impurity removing wheels close to the guide wheel, so that the efficiency of removing impurities such as broken rod cores can be improved, and the impurities can be removed as early as possible; cold drawing round steel is uniformly distributed on the surfaces of three pairs of impurity removing wheels which are to be output from the impurity removing device on the cotton stalk bark, and rotating wheels which are uniformly distributed with the cold drawing round steel and rotating wheels which are uniformly distributed with cold rolling steel sheets are arranged in a staggered mode in each other pair of impurity removing wheels.

All the upper and lower impurity removing wheel cross (overlap) control area central connecting lines are completely superposed with the upper and lower guide control wheel cross (overlap) working area central connecting lines, which is equivalent to the forward route of the cotton stalk skin by transferring, straightening and straightening, and the mutual spacing is in a proper small range, and the upper and lower cross impurity removing wheels with round steel uniformly distributed on the surface and the upper and lower cross impurity removing wheels with cold-rolled steel sheets uniformly distributed on the surface are alternately arranged, which is very favorable for the transfer of the cotton stalk skin and can ensure that the separated cotton stalk core can smoothly fall into the vehicle belly.
Furthermore, the linear speed of the first pair of impurity removing wheels close to the guide control wheel is more than 30% of the linear speed of the guide control wheel, which is a precondition for ensuring that the cotton stalk barks smoothly enter the impurity removing device.
Furthermore, the working surface of the cold-rolled steel sheet is an arc surface formed by chamfering.
