An adaptive spreading vehicle and spreading method

Abstract

The invention discloses an adaptive spreading vehicle and a spreading method, comprising a vehicle body, a beam connected to the vehicle body, a plurality of sprinklers connected to the beam, a transverse guide rod connected to the vehicle body, and a transverse guide sleeve provided on the sliding sleeve of the transverse guide rod , the horizontal guide rod is connected with the horizontal guide sleeve through the second spring; the horizontal guide sleeve is connected with a baffle plate arranged in the vertical direction, and one side of the baffle plate is rotated to be provided with a horizontal guide wheel suitable for curbstones, and the baffle plate is also connected with a horizontal The rack and the fixed plate are provided; the adjustment rod is slidingly connected in the nozzle, and the upper end of the adjustment rod passes through the nozzle to connect with the screw rod, and the screw rod is equipped with a screw nut, and the upper end of the screw rod is connected with a gear, which meshes with the rack; fixed The plate is provided with a limiting groove, and the screw nut is connected with a sliding key, which is slidably arranged in the limiting groove and slides along the horizontal direction. The invention can automatically adjust the spreading range according to the width and undulations of the road surface, so as to solve the problem of secondary spreading or subsequent cleaning inconvenience.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an adaptive spreading vehicle and a spreading method. Background technique [0002] At present, before the construction of the asphalt surface layer, in order to reduce the trimming of the asphalt pavement, resulting in waste of asphalt mixture and environmental pollution, it is generally used to construct concrete works such as curbs, drains, hard shoulders, and concrete guardrails. In order to avoid spreading through layer, sealing layer and sticky layer during the construction of pavement surface layer. Concrete projects such as curbs, rapids, hard shoulders, and concrete guardrails are polluted. The traditional method is to cover them with geotextiles, plastic films, etc., thereby increasing labor and material waste. [0003] When spreading the penetration layer, sealing layer and sticky layer, in the process of protecting the curbs, rapids, hard shoulders, concret...

AI Technical Summary

Problems solved by technology

To pollute concrete projects such as curbs, rapids, hard shoulders, concrete guardrails, etc., traditional methods use geotextiles, plastic films, etc. to cover, thereby increasing labor and material waste

[0003] When spreading the permeable layer, sealing layer, and sticky layer, during the protection process of concrete works such as curbs, rapids, hard shoulders, and concrete guardrails in advance, the impact of spraying will cause more or less pollution, and the later cleaning will waste manpower and material resources. It affects the appearance quality of concrete, and because the spreading device cannot adjust the distance from the curb during the spreading process, the spreading cannot reach the edge, which is easy to cause secondary labor, and is not conducive to subsequent cleaning work
