Buffering regulation mechanism for roller of suction plate

Abstract

The invention discloses a buffering regulation mechanism for a roller of a suction plate. The buffering regulation mechanism comprises the roller, a roller support, a regulating bolt, a fixing seat, a connection seat, a supporting bolt, a spring and a guide sleeve. The roller support comprises a first side plate and a second side plate, and the lower portion of the connection seat is mounted on the upper front portion between the first side plate and the second side plate through a hinge pin. The lower end of the regulating bolt is positioned on the upper rear portion between the first side plate and the second side plate to form hinge connection, the upper end of the regulating bolt is positioned in an elongated hole in the rear of the top surface of the fixing seat, and a locking nut is mounted at the upper end of the regulating bolt and positioned above the top surface of the fixing seat. A connection plate is arranged in the inner upper middle between the first side plate and the second side plate, the upper end of the supporting bolt is arranged below the middle of the top surface of the fixing seat, the guide sleeve sleeves the supporting bolt, the spring sleeves the guide sleeve and the supporting bolt, a spring limiting ring and a regulating nut are mounted on the supporting bolt, and the lower end of the spring is positioned on the upper surface of the connection plate.

Description

technical field

[0001] The invention relates to a road sweeper, in particular to a suction cup roller buffer adjustment mechanism. Background technique

[0002] An existing road sweeper includes a suction cup assembly. The suction cup assembly includes a suction cup main body, a roller, a roller bracket, a limit bolt and a limit bolt seat. The roller is set on the roller bracket, and there are two waist-shaped grooves on the roller bracket, and two bolts are installed in the two waist-shaped grooves of the roller bracket and the screw holes on the side of the main body of the suction cup, so that the roller bracket is fixed on the on the side of the suction cup body. The limit bolt seat is arranged on the side of the suction cup main body, the limit bolt is worn on the adjusting bolt seat, and the lower end of the limit bolt bears on the roller bracket. When the roller is worn out and the position of the roller relative to the main body of the suction cup needs to be adju...
