Uniform distribution device for stone chips remained in municipal road construction

Abstract

The invention provides a device for uniformly spreading stone chips after municipal road construction, which includes a threaded rod, a scraper, a scraper, a flattening roller and a spike roller; one end of the conveying shaft is connected across a circular material barrel In the bearing on the inner side of the top end of the support, a screw conveying leaf is also welded on the conveying shaft, and the threaded rod at the upper end of the inner side of the support passes through the hole to fix the sliding cross bar, and the flattening roller and the wolf tooth roller pass through the two. The fixed shaft at the end passes through the waist circle through hole and is screwed with a locking handwheel. The scraper plate is fixedly arranged on the bottom inner side of the two sets of sliding cross bars, and the front side of the lower end of the scraper plate is connected with a scraper plow by bolts. The height of the stone chips is adjusted by using the scraping plate and the scraping plow. At the same time, the scraping plow increases the strength of the scraping plate. The gap between the stone chips is adjusted through the teeth on the spike roller to ensure that the density of the stone chips after spreading is consistent. , and use the flattening roller to flatten the stone chips again, so that the stone chips on the road surface can be spread more evenly.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to a device for evenly spreading stone chips after municipal road construction. Background technique [0002] There are two ways of spreading stone chips in the existing road maintenance construction. One is manual spreading, workers use shovels to throw stone chips, which is very uneven and labor-intensive. This method is gradually replaced by mechanical spreading. The other is the traditional stone chip spreading machine, which distributes the stone chips flowing down from the dump truck through a trapezoidal diverter plate to the bottom edge (wide side) of the trapezoid through many guide grooves on the plate, and then Then it falls onto a baffle and falls to the ground along the baffle. [0003] The application number is: in the Chinese patent of 201120131936.X, disclose a kind of multifunctional asphalt pavement paving machine, it has increased on the basis of prior...

Problems solved by technology

[0005] Based on the above, the inventors have found that with the traditional stone chip sprinkler for road construction, after the stone chips are sprayed, the left and right sides of the road surface are uneven, and the bulk density of the stone chips on the road is also quite different, and it is impossible to correct the stone chips.
