(57) Abstract Objective As for screw conveyer device of former paving equipmentThe case of pavement construction way adaptation to pavement width, in the crosswise left and rightMost it succeeds the auxiliary screw in those of a state where it is compacted adds it is denseIt means to do pavement construction with to a length of desire butStructure of joint part of screw shaft of auxiliary screwBecoming the structure which it cannot turn conversely, it reaches, being able to turn conversely, structureStructure being complicated, inconvenience was many. As for this deviceIt is something which designates that the above-mentioned problem is solved as purpose. Constitution Screw feather 13 outside cylindrical shaft 20On 1 edge sides of the screw shaft 12 which is adhered to lap the pin sectionInterpolating material 21, the check pin 2 which it provides in that pin component 21Screw shaft 12 of opposite side because 2 jointsTo engage in slit 27 for the stopping pin engagement which is provided on other end side, the uTo make the ru way, on other end side of aforementioned screw shaft 12 facilitiesColumn tabular ring 23 and 24 those tabular rings 23,By providing floating ring 25 between 24 the slitThe pin component 22 which is engaged in the part of 27 is made the engage and release unrestricted,The reciprocal revolution possible installation and removal type screw and its installation and removal expression which become the teThe paving equipment and the repair machine which possess the screw.
