As a kind of equipment to realize slope greening, with the rapid development of China's economy and the development of science and technology, the technical level of spraying machine is constantly improving, innovating and updating, and it is also promoting the construction of ecological environment in our country.

The advantages of the first generation spray machine dry spray machine:

1. Nozzle thickness

2. Simple construction

Defects:

1, low efficiency

2. High construction cost (1) More vulnerable parts 2. Air compressors, generators, mixers and other supporting equipment have high procurement costs;

3, high labor costs (high labor costs), construction risk;

4, rain is easy to wash (the upper dry materials, can not use wet materials, easy to cause construction delay);

5. The pipeline is easy to be blocked, and the supporting equipment is inconvenient to move.

The second generation: hydraulic pumping wet spraying machine (also known as multi-purpose wet spraying machine, small pump truck)

Advantages:

1. The mixture concentration is high, and the spray layer thickness is high (the concentration can reach 80%, the spray layer is 3~5cm, and the spray layer can be 800 square meters per day)

2. High efficiency without clogging

3. Continuous construction

4. The particle size of the spray is 30 mm

5. Conveying distance: 200 meters horizontally and 100 meters vertically

Defects:

1, the cost is relatively high

The supporting facilities are complete, and the supporting equipment such as air compressor, mixer, generator, etc. are required in the early stage; the hydraulic sprinkler irrigation machine is also used for maintenance in the later stage, and the procurement cost of the whole mechanical equipment is very high.

High fuel consumption (600-1000 yuan per day), high cost of use;

The need for more manpower, resulting in higher labor costs;

2. The spraying machine has a complex structure and many supporting equipment, which makes it difficult to repair and maintain. The level of operators is generally not easy to operate, and it is difficult to operate, and it is suitable for professionals to operate;

3. There are many vulnerable parts of the machine, and the service life of the main vulnerable parts is generally about 1000-2000m3, which is more troublesome to replace, and requires a lot of after-sales service, which is very inconvenient on the construction site;

4. Due to the large aggregate particles, up to 30mm, the possibility of blocking the pipeline is greater. Steel pipes are usually used, but once blocked, it often takes a day;

5, the construction risk is larger (with dry injector)

6. It is difficult to move on thin slopes and slopes, and it is not very convenient;

The third generation of agricultural machinery: soil planter

Features:

The concentration of the mixture is 50% ~ 70% higher, slightly thinner than the second generation;

2, the cost is relatively low (whether it is procurement, labor, use costs are relatively low)

3, greatly improved the stability of the building

4, easy to move, especially suitable for medium, low slope, scattered slope

5. Easy to construct, the machine can be operated separately, easy to operate.

Technical Analysis of Slope Greening Spray Planter

Introduction of Concrete Wet Spraying Machine Foundation

With the rapid development of the modern construction industry, construction equipment is constantly innovating, which has brought a qualitative leap in engineering quality and efficiency. Today, we have the honor to introduce you to a high-profile new construction weapon-Saner heavy industry 25 meters long arm wet spray machine. This equipment integrates the three main functions of wet spraying, concrete conveying and soil spraying. With its excellent performance and powerful functions, it has attracted wide attention in the industry once it is launched.

Saner Heavy Industry warmly welcomes the leaders of the North Center of Real Estate Registration City to come and guide and participate in the grand party building activities.

In the beautiful spring and the recovery of all things, Saner Heavy Industry welcomed the leaders of the North Center of Real Estate Registration City. Their visit this time is not only a concern and support for our work, but also a great importance and affirmation of the party building work of Sany Heavy Industry. We are deeply honored, but also feel a great responsibility.

Saner Heavy Industry Wet Spray Truck Nozzle Test: Accurate Direction Control and Steering Flexibility to Create Efficient Spraying Tilt

Recently, Saner Heavy Industry conducted a special test on the nozzle of the wet spray trolley, focusing on the flexibility of its spraying direction and steering. This test not only shows Saner Heavy Industry's ultimate pursuit of product details, but also lays a solid foundation for building an efficient spraying weapon.

Saner Wet Spraying Machine to Aid Shantou, China Railway 14th Bureau Subsea Tunnel Project

Recently, an advanced Saner wet spraying machine was successfully sent to Shantou, Guangdong, which will provide important support for the construction of the "Shantou Bay Subsea Tunnel" project undertaken by the 14th Bureau of China Railway. The arrival of this wet spraying machine marks another solid step in the mechanization and automation of the project construction, and injects new impetus into the smooth progress of the project.

Saner Heavy Industry Wet Spraying Machine Helps China Railway 14th Bureau

Recently, the SRSP40A manipulator wet spray trolley with its own air compressor developed by Saner Heavy Industry was sent to the construction site of Qipanqiao Tunnel.
