Background technique

At present, before the construction of the asphalt surface layer, in order to reduce the trimming of the asphalt pavement, resulting in the waste of asphalt mixture and environmental pollution, the construction of concrete works such as curbs, drains, hard shoulders, and concrete guardrails is generally adopted first. 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.

When spreading the penetration layer, sealing layer and sticky layer, in the process of protecting the curbs, rapids, hard shoulders, concrete guardrails and other concrete projects in advance, the impact force of spraying will cause more or less pollution, and the later cleaning will waste manpower and material resources. It affects the appearance quality of the 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.

During this process, the sliding key 24 slides in the limiting groove 19 to drive the nut 22 to slide horizontally.

When advancing on the undulating road, the undulating road drives the traveling wheel 1 to move upward, which in turn drives the baffle 4 to move upward, the vertical guide rod 23 moves upward in the vertical guide sleeve 7, and the vertical guide rod 23 drives the fixed plate 15 to move upward. Under the action of the position slot 19, the nut 22 is driven to move upward by the sliding key 24, the nut 22 drives the screw 20 to move upward, and the screw 20 drives the adjustment rod 16 to move upward, so that the spraying area of the nozzle 12 is reduced. During the process, the gear 13 and the rack 14 slide relative to each other, and the gear 13 and the rack 14 are always in meshing state.

In step S2, when the adjusting rod 16 moves downward, the distance between the adjusting rod 16 and the nozzle decreases, so that when the pressure mechanism drives the liquid in the liquid chamber 17 to flow, after the liquid is ejected through the nozzle, the spreading area increases.

It should be noted that the lateral guide wheel 3 in the present invention can automatically adapt to the width of the road surface according to the width of the roadside stone 2. When encountering a wider road surface, the rack 14 drives the screw rod 20 to rotate through the gear 13.
