[0030] As shown in Figs. 1-4 The outer circumferential surface of the eccentric rotating shaft 3 is fixedly sleeved with two eccentric cleaning wheels arranged in a symmetrical manner, the two eccentric cleaning wheels are located on both sides of the connecting chain, and the eccentric cleaning wheels are arranged to shake and remove the impurities adhered to the surface of the mulch during the rotation of the eccentric cleaning wheels, thereby increasing the cleanliness of the recovered mulch.

[0031] As shown in Figs. 1-4 The cleaning scraper 13 is made of nylon, which reduces the noise generated during cleaning and can further reduce the amount of soil brought up by the rotation of the cleaning scraper 13 while retaining the basic wear resistance; the two shaft positioning plates 1 are fixedly connected by screws and are jointly provided with a baffle 15; the outer circumferential surface of the driving shaft 2 is fixedly sleeved with two symmetrical film-removing plates 7, the film-removing plates 7 are located on both sides of the connecting chain 5, and the radius of the film-removing plates 7 is greater than the length of the film- forming teeth 6.
