Embodiment Construction

[0045] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0046] such as 1 and figure 2 The structure of the screed compacting beam according to Embodiment 1 of the present invention is shown. The screed compaction beam for pavers consists of:

[0047] A drive shaft 1, which is connected to the drive motor of the paver;

[0048] The cam 2 is provided with a raised portion 21, which is sleeved on the drive shaft 1 and coaxially linked with the drive shaft 1;

[0049] Transmission rod 3, the upper end of the transmission rod is in contact with the outer peripheral wall of the cam 2, and its lower end is fixedly connected with the blade 6 of the paver;

[0050] The limiting mechanism is used to make the transmission rod 3 move in the vertical directio...

Abstract

The invention discloses a screed plate compaction beam, a screed plate and a paver. The screed plate compaction beam comprises a driving shaft, a cam, a transmission rod and a transmission rod resetting mechanism. The driving shaft is connected with a driving motor; the cam is sleeved on the driving shaft and is coaxially linked with the driving shaft; the upper end of the transmission rod is contacted and connected with the peripheral wall of the cam, and the lower end of the transmission rod is fixedly connected with a cutter blade; and the transmission rod resetting mechanism is used for tightly pressing the upper end of the transmission rod onto the cam. According to the screed plate compaction beam, when a bulge part rotates to the transmission rod when the cam rotates, the transmission rod is extruded and the cutter blade is driven to move downwards; and when the bulge part rotates away from the transmission rod, the transmission rod is reset, the cutter blade is driven to move upwards, vibratory pulse is produced, and the back-and-forth movement of the screed plate compaction beam is realized. Compared with an existing hydraulically driven screed plate compaction beam, according to the screed plate compaction beam, the structure is simpler, so that the cost is lower on the one hand, and the detachment and the post repairing of the equipment are convenient on the other hand.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a screed compacting beam, a screed and a paver. Background technique [0002] The paver is a kind of engineering machinery that spreads the mixed materials of different grades evenly, rams and compacts them, and irons them to make them smooth. It is an indispensable key equipment for the construction of expressways and high-grade roads. In recent years, with the continuous extension of highway construction mileage, the role of paver in road construction has become more and more important. [0003] The screed is the key operating device of the paver, which plays a vital role in the compactness and smoothness of the road surface. The screed compacting beam is a device whose compaction frequency is higher than that of the paver vibrator on the screed. Its main function is to generate high-frequency reciprocating motion in the vertical direction. The pavement after the soleplat...
