Spiral joints, main joint segment, spiral material division device for paver and paver

Abstract

The invention provides spiral joints which comprise a shaft (1) and spiral blades (2) arranged on the shaft (1), wherein one end of the shaft (1) is provided with a thread. Correspondingly, the invention also provides a main joint section. In addition, the invention also provides a spiral material division device for a paver and the paver. As the spiral joints provided by the invention are in threaded connection with a main shaft of the main joint section, any mechanical equipment is needed, the spiral joints can be conveniently and quickly arranged on the main joint section of the spiral material division device or can be removed from the main joint section, further, the length of the spiral material division device can be conveniently adjusted, so that the requirements of different paving working conditions can be met. In addition, during the working process of the paver, the spiral joints can be screwed by the reverse action of paving materials on the spiral joints, so that the automatic anti-loosening function can be realized.

Description

technical field [0001] The invention relates to the field of road construction machinery, in particular to a screw joint, a main segment, a screw material distributing device for a paver and a paver. Background technique [0002] Concrete paver is a road construction machine that spreads concrete mixture evenly on the pavement base, and then completes the pavement of concrete pavement through operating procedures such as vibrating and leveling. Asphalt paver is a special construction machine for asphalt pavement. It spreads the mixed asphalt concrete material evenly on the pavement sub-base or base, and pre-compacts and shapes it to a certain extent to form an asphalt concrete base or Asphalt concrete surface. The above two types of paver are indispensable mechanical equipment in road construction machinery, and the screw distribution device is an important part of the paver. [0003] like figure 1 As shown, the existing screw distributing device generally includes a main...

AI Technical Summary

Problems solved by technology

Since the main shaft 5 and the extension shaft 12 are connected to each other through connecting bolts, washers and nuts passing through the holes, the replacement of the extension shaft 12 requires repeated loosening and tightening of the connecting bolts, washers and nuts. Conducive to quick disassembly

In addition, the existing extension shaft 12 is usually heavy and must be disassembled with the help of mechanical equipment, which brings great inconvenience to the construction site
