Plaster sprayer for road

Abstract

The invention belongs to the technical field of road construction machine and discloses a sprayer for the white limestone used for road. The invention is mainly characterized in that the sprayer includes a body with a running mechanism; the front part of the body is provided with a storage cabin; the bottom part of the storage cabin is provided with a material feed mechanism which extends backwards through the bottom part of the body; the two sides of the material feed mechanism at the back part of the body are respectively provided with a first material backward discharge mechanism and a second material backward discharge mechanism; the material feed mechanism, the first material backward discharge mechanism and the second material backward discharge mechanism are dynamically connected the running mechanism through a power transmission mechanism with a clutch; an external moving paving mechanism is arranged above the material feed mechanism on the back part of the body; a material thickness control drawing template is arranged above the material feed mechanism at the back of the external moving paving mechanism. The machine can lead the white limestone to be sprayed more uniformly, thus reducing the working intensity and reducing the road construction cost. The invention can be applied to spray various road white limestone or cement, etc.

Description

technical field [0001] The invention belongs to the technical field of road construction machinery, in particular to a road-use lime spreader. Background technique [0002] With the acceleration of economic construction, there are more and more road constructions of various grades that are indispensable for economic development. During the road construction process, it is necessary to mix a large amount of white ash with the subgrade soil evenly and then compact it, so that the road subgrade is stronger. At present, in the process of highway construction, there are two methods of mixing lime with roadbed soil: the first method is to transport limestone to the roadbed, divide it into several piles, and then manually sprinkle limestone on the ground of the foundation , and then use a rotary tiller to mix lime and soil evenly; the second method is to transport the soil of the subgrade to the admixture field by transport vehicles. The mixed material is transported to the roadb...

AI Technical Summary

Problems solved by technology

For the first method, there are the following defects: the first, with the increase of workers' wages, the cost of the road has been increased, and because of the corrosiveness of lime, it will have a certain impact on the health of the builders; the second, due to Human-made reasons often result in a lot of white ash in and around the white ash pile, but less white ash in places far away from the white ash pile, resulting in uneven spreading of white ash, resulting in uneven mixing of white ash and soil in the roadbed; third, due to the uneven surface of the soil roadbed, Where there are pits, there is more white ash, and where there are protrusions, there is less white ash, which will also cause uneven white ash

Although the second method can improve the uniformity of lime and soil mixing, transporting the subgrade soil back and forth greatly increases the construction cost of the road. At present, this method is only used for expressways with high road requirements.
