Xinjiang is an important high-quality cotton production base in China, and because Xinjiang widely adopts a planting mode of drip irrigation under a film, a certain amount of residual film is inevitably mixed in the cotton during the mechanical picking process. The existence of the residual film seriously influences the quality of cotton and brings about great economic loss. At present, the seed cotton plastic film residue problem is solved by foreign fiber cleaning equipment in the cotton processing process, and the plastic film residue cleaning and protecting device in the mechanical picking process is fewer by a device matched with a cotton picker. The matched residual film cleaning devices of the cotton picker disclosed at present are CN201310009701.7 and CN201620489653.5, and the residual film cleaning is carried out before seed cotton enters a cotton collecting box by means of a seed cotton residual film cleaning method in a cotton processing link.
Because cotton picker adopts wind power to carry seed cotton in the mechanical picking process, under the effect of wind power transmission, the picking head cavity is easy to form negative pressure, and because the bottom plate of the existing cotton picker is provided with impurity leakage holes for removing impurities such as bell shells mixed into the picking head cavity in the seed cotton picking process, residual films are easy to be sucked up and mixed into the seed cotton through the impurity leakage holes under the effect of the negative pressure of the picking head cavity.
Therefore, in order to solve the problem that the quality of seed cotton is reduced due to the fact that the residual film is easily sucked into the picking head through the impurity leakage holes and mixed into the seed cotton, and the income of a planting owner is reduced, a device and a method for reducing the mixing of the residual film into the seed cotton are urgently needed.
