Dual vibrators with pulleys, screed and pavers

Abstract

The invention discloses a dual vibrating mechanism provided with a belt wheel, an ironing plate and a paver. The dual vibrating mechanism provided with the belt wheel is used for compacting and paving materials and comprises a vibrating shaft, vibrating bearing seats, vibrating blades, a fixed bearing seat and the belt wheel. A fixed bearing seat installation section and vibrating bearing seat installation sections are arranged on the vibrating shaft. The vibrating bearing seat installation sections include the first vibrating bearing seat installation section and the second vibrating bearing seat installation section, and the first vibrating bearing seat installation section and the second vibrating bearing seat installation section are eccentric relative to the axis of the fixed bearing seat installation section and are located on the inner side of the fixed bearing seat installation section. The vibrating blades include the first vibrating blade connected with the first vibrating bearing seat and the second vibrating blade connected with the second vibrating bearing seat. The belt wheel is arranged at one end of the vibrating shaft and located on the outer side of the fixed bearing seat. According to the dual vibrating mechanism provided with the belt wheel, the ironing plate and the paver, the maximum alternating stress of the vibrating shaft can be greatly reduced, and the capacity of resisting fatigue loads of the vibrating shaft can be further improved.

Description

technical field [0001] The invention relates to a vibrating mechanism, in particular to a double vibrating mechanism with pulleys. The invention also relates to a screed and a paver having the double vibrating mechanism with pulleys of the invention. Background technique [0002] The screed is a very important working device on the paver, which is responsible for smoothing and compacting the paving materials and finally forming the paved road surface. Such as figure 1 As shown, the screed generally includes devices such as a screed frame 1, a bottom plate 2, a vibrating mechanism 3, and a baffle plate 4. The bottom plate 2, the vibrating mechanism 3, and the baffle plate 4 are usually installed on the screed frame 1. Bottom plate 2 is responsible for forming the paving material, vibrating mechanism 3 is responsible for initial compaction of the paving material, material stopper 4 is used to guide and limit the vibrating mechanism 3 and prevent the paving material on the fr...

AI Technical Summary

Problems solved by technology

However, if the shaft diameter of the vibrating shaft is increased, the overall size of the double vibrating mechanism will increase, which is extremely unfavorable for the screed that requires a compact space

If the pre-tightening force of the belt is reduced, the maximum torque and power that can be transmitted will be reduced. At this time, more than one set of motors, belts and pulleys are required to transmit power to the vibrating mechanism, which will increase the cost and the overall screed. layout difficulties
