The construction technology of spraying machine is an advanced plant construction technology introduced by Europe, North America, Japan and other countries. In the late 1990 s, the Science and Technology Research Institute of the Ministry of Transport introduced sandblasting protection technology from Japan, and it was rapidly popularized and applied in China. Now it has become an effective plant planting method for highway slope vegetation, river embankment biological protection and large-scale green space planting. In engineering construction, the mechanical properties of sprinkler irrigation machinery are directly related to the quality and efficiency of engineering construction.

The whole frame of the machine is carefully welded with 120 channel steel, the tank body is made of 5mm steel plate, and the key parts of the bottom of the tank body are reinforced with 20mm thick steel plate to ensure that the whole machine is strong, durable and stable in transportation;

2. The special spiral mixing and conveying material structure at the inlet of the pump can convey viscous materials and increase the thickness of the spray layer;

The whole machine adopts mechanical stirring and chain transmission, which is easy to use, high transmission efficiency, easy to repair and maintain for workers, and easy to operate. The stirring adopts the combination of spiral blade mechanical stirring and reflux flushing stirring to form three-dimensional stirring, which can effectively improve the mixing uniformity;

4, using a single diesel engine drive, low fuel consumption, easy operation and easy maintenance, reduce the cost of use and work costs;

5. Equipped with 360-degree freely rotating universal nozzle, and equipped with long and short fan nozzles and guide pipe valves, which are convenient to change according to different working surfaces;

The core pump of the spraying device adopts a special pressurized multi-stage pump, which can spray viscous materials from the nozzle at high speed with a direct range of 20-50m, reducing construction difficulty, improving efficiency and increasing reliability. The high slope can be connected with rubber wear-resistant pipes, increasing lift and facilitating construction.

The spraying machine is suitable for greening and spraying in places where plants are difficult to grow, such as rocks, hard soil, sandy soil, barren land, acid soil, arid areas, coastal dams, etc. It is widely used in highway greening, high-speed railway slope greening, mine greening, ecological restoration, desert management and other projects.

Mixed:

The complementary characteristics of grass species, such as deep and shallow roots, leguminous and gramineous, foreign and local, early and late development, are used for mixed seeding.

(1) Seeds: Select excellent shrubs and herbs with good resistance, adaptability, barren tolerance and drought tolerance, such as native trees, shrubs and grass seeds.

(2): Natural organic soil improvement materials are the main body, mixed with various organic and inorganic materials that are beneficial to plant growth.

(3) materials and nutrient materials: chemical synthetic fertilizers and slow-acting fertilizers are used to provide nutrients for different periods of plant growth.

(4) Stabilizer: Wood fiber is used to increase the strength and porosity of the mixture and enhance the stability of the spraying layer.

(5) Binder: It is made of powdered high molecular polymer and natural plants. It is used to improve the adhesion of wood fibers to the soil to ensure that the spraying layer is resistant to wind and wipers without falling off, and is bonded with the slope surface without slipping and losing, forming a good aggregate structure.

(6) Water: The water required for the growth of ordinary plants requires pollution-free water. Now our country is working hard to build greening, and the protection of the environment will benefit the future (landscaping, highway slope greening, urban garbage landfill greening, greening restoration after mining, etc.), to save the haze weather, the spraying machine is very good Play a time-saving, labor-saving, convenient and fast role! Therefore, the research and application of spray seeding technology will certainly promote the improvement of the greening level of roads and railways in China, and make certain contributions to the greening of land, ecological protection and soil and water conservation.
