Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-2. In the embodiment of the utility model, a low-friction bracket for a drum granulator includes a base 1, a support shaft 5, a support wheel 6, an inner baffle 7 and an outer retaining ring 8. The base 1 has a symmetrical structure, the front is trapezoidal, and an inverted trapezoidal groove is formed on the upper bottom of the trapezoidal shape. Two bumps 2 are formed at both ends of the groove. Such arrangement can reduce the The amount of steel required for the base 1, the side of the base 1 is trapezoidal, the upper bottom of the trapezoid is provided with a rectangular groove, and two supporting seats 11 are formed at both ends of the groove, and the rectangular groove is used to avoid the support wheel 6 and the inner baffle 7 and the rotation track of the outer retaining ring 8, two bumps 2 are provided with two support wheels 6, the support wheels 6 are cylindrical, and a through hole is opened in the center, and the support shaft 5 passes through the through hole of the support wheel 6 to support The wheel 6 and the supporting shaft 5 are fixedly connected by welding, and two bearings 4 are fixedly sleeved at both ends of the supporting shaft 5, and the two bearings 4 and the corresponding bearing seats 3 are installed on the supporting seat 11, and the bearing seat 3 is fixed on the supporting seat by bolts. On the seat 11; the two ends of the support wheel 6 are provided with an inner baffle 7, the inner baffle 7 and the support wheel 6 are of an integrated structure, the inner baffle 7 is disc-shaped, and its diameter is greater than the diameter of the support wheel 6, An outer retaining ring 8 is arranged outside the inner retaining plate 7, and the center of the outer retaining ring 8 coincides with the center of the inner retaining plate 7. The diameter of the outer retaining ring 8 is larger than that of the inner retaining plate 7. 9 connection, the inner baffle 7, the outer retaining ring 8 and the connecting shaft 9 are integrated structure, the connecting shaft 9 is arranged between the inner baffle 7 and the outer retaining ring 8, the number of connecting shafts 9 is multiple, along the inner retaining The center of the plate 7 is distributed symmetrically, the connecting shaft 9 is covered with balls 10, the diameter of the balls 10 is greater than the thickness of the inner baffle 7, and the balls 10 can rotate around the connecting shaft 9.
