[0008] The utility model is further provided as follows: the cross section of the side of the baffle facing the wheel body is arranged in the shape of two sharp heads.

[0009] The utility model is further provided as follows: a fitting groove is formed on the sleeve, and the fitting groove is communicated with the through hole.

[0010] The utility model is further provided as follows: a cover is rotatably arranged on the sleeve, the rotating shaft of the cover is arranged at the central position between the two short sides, the cover is fitted with the fitting groove and shields the through hole.

[0011] The utility model is further provided as follows: a V-shaped plate is further fixedly arranged on the sleeve.

[0012] The baffle is made of polyurethane plate, and the sleeve shell and the cover are made of cast iron.

[0013] In conclusion, the self-cleaning guide wheel has the advantages that: in the process of rotating the guide wheel, the abutment of the baffle to the guide wheel can clean the area of the guide wheel which is not contacted with the chain, so that the effect of scraping the soil attached to the guide wheel is achieved, and the service life of the guide wheel is prolonged.
