Specifically, the first base 21 and the second base 22 are both provided with idler mounting grooves 40 at both ends thereof, and the first idler 500 and the second idler 600 are mounted on the first base 21 and the second base 22 through the idler mounting grooves 40. The shape of the idler mounting groove 40 is matched with the shaft end shape of the first idler 500 and the second idler 600, and when the idler mounting groove is mounted, the first idler 500 and the second idler 600 are directly placed into the idler mounting groove 40 and clamped.
As shown in fig. 3, the anti-shock bracket 30 includes an inner sleeve 31, an outer sleeve 32, and a damping spring 33. The inner sleeve 31 and the outer sleeve 32 are respectively hinged with the second base 22 and the base 20, a connecting screw 34 is arranged in the inner sleeve 31, a through hole is formed in the outer sleeve 32, the connecting screw 34 penetrates through the through hole and is in threaded fit and fixed with a connecting nut 35, the buffer spring 33 is sleeved on the connecting screw 34, and two ends of the buffer spring respectively abut against the end portions of the inner sleeve 31 and the outer sleeve 32.
Due to the matching of the connecting screw 34 and the connecting nut 35, the inclination of the second base 22 and the base 20 can be adjusted by only rotating the connecting nut 35 to change the relative position of the threaded connection, so that the inclination angles of the two second carrier rollers 600 are changed, and the concave profile of the belt is changed. Meanwhile, since the two ends of the buffer spring 33 respectively abut against the ends of the inner sleeve 31 and the outer sleeve 32, when the second idler 600 and the second base 22 are impacted by large solid materials, a buffering effect can be achieved.
