Study on stability of rake teeth inserting soil of chain rake type mulching film recovery machine based on Adams

Traditional rake type mulching film recycling machine has the problem of difficulty in unloading and packing film, poor continuity of the work. In order to solve such problems, this paper designs a kind of chain rake type mulching film recycling machine which can realize continuous raking film, collecting film, transporting film, shaking off soil, unloading film. Rake teeth is the basic part of chain rake mulching recycling machine. The stability of rake teeth’s inserting soil is an important factor to ensure recovery efficiency of the plastic film recovery. By virtual prototype simulation, this paper study the influence of different factors on the stability of rake teeth inserting soil. The results are as follow: ①The speed of chain rake has no significant effect on the stability of rake teeth inserting soil; ②Reducing resistance of rake teeth in the process of working, is conducive to improve the stability of rake teeth inserting soil; ③Appropriate increasing elastic modulus of chain rake, is helpful to enhance the stability of rake teeth inserting soil.
