Lime powder uniform paving device

Abstract

The invention relates to a lime powder uniform spreading device which effectively solves the problems that in the existing small engineering pavement lime powder spreading and flattening process, theefficiency is low, and meanwhile occupational diseases of workers are likely to be caused. According to the technical scheme, the device comprises a vertical plate, the two vertical plates can synchronously move left and right; the left side and the right side of each vertical plate are each provided with a dispersing unit. Each group of dispersion units comprises a scraper blade which is obliquely arranged; the two scrapers can synchronously move back to back or face to face; the front end and the rear end of each scraping plate are each provided with a pin shaft penetrating through the corresponding vertical plate. The scraping plate can rotate around the pin shaft; each pin shaft is sleeved with a ratchet wheel arranged on the outer side of the corresponding vertical plate. A circular ring is coaxially fixed on the outer side of each ratchet wheel; the circular ring cannot rotate, pawls matched with the ratchet wheels are evenly distributed on the inner circumference of the circularring, the ratchet wheel and pawl structures can prevent the upper ends of the two scraping plates from rotating outwards, an electric push rod capable of being pushed out horizontally in two directions is arranged between the two ratchet wheels on the same side, and the two extending ends of each electric push rod make contact with and support the circular ring on the corresponding side.

Description

Technical field [0001] The invention relates to the field of road construction equipment, in particular to a lime powder uniform paving device. Background technique [0002] In the initial stage of pavement paving, a layer of lime powder needs to be spread evenly on the roadbed to improve the properties of the roadbed. For large-scale engineering pavements, there are special lime paving vehicles for paving, but for small-scale engineering pavements, at this stage Manual spreading is also carried out with a dump truck. The spreading process is as follows: first use a dump truck to unload the lime powder on the road at intervals, and then the workers use a hoarding board to surround piles of lime powder, and use hand tools such as rakes to perform Pile the piles of lime powder in the frame of the fenced wall. This method is low-cost and suitable for pavement paving of small projects, but the paving efficiency is low. At the same time, the working environment of workers is bad, and ...
