[0034] Second embodiment:

[0035] Based on the first embodiment, please refer to Figure 6 to Figure 8 ,in Figure 6 is a three-dimensional stereogram of a second embodiment of the present invention, Figure 7 is a front view of a second embodiment of the present invention, Figure 8 The present invention Figure 7 Sectional view along line DD.

[0036] The present invention provides a grinder for a gearbox housing of an agricultural machinery, which also includes a supporting mechanism and a dust collecting mechanism 201.
