The rise of nanometers

On one side of the container, Du Jinhua and others and the equipment manufacturing company of Snail Industry re-modified the equipment.

There has been a draft of the design drawing before, and now we are renovating the equipment while improving the design.

According to the plan of the saline-alkali land transformation project, an excavator is first used to dig out the soil layer of the saline-alkali land, and then it is preliminarily screened to separate large stones and shrubs.

The saline-alkali soil after preliminary screening is sent to the desalination truck, which separates the salt in the soil. After the desalination soil is completed, it is divided into two parts.

Half is directly backfilled, and half goes into the mixing truck, mixed with organic fertilizer, and then backfilled to become the topsoil layer.

The equipment that needs to be modified now is desalination trucks and mixing trucks.

Among them, the mixer truck is relatively easy to modify, as long as it has the functions of soil loading, mixing and unloading.

The focus now is on the desalination truck. The desalination truck can be regarded as a smaller version of the desalination workshop, and there is no technical difficulty.

The overall design adopts a modular design, using the chassis of a large engineering transport vehicle, and is divided into an earth entry system, a desalination cabin, a dehydration cabin, an earth unloading system, an internal water circulation system, a power supply system, and a salt unloading system.

The preliminary design length of the desalination truck has reached 12 meters, width 2.5 meters, and height 4.5 meters, which are basically the limit parameters of highway trucks.

Equipped with independent diesel power generation vehicles, primary screening vehicles, salt storage vehicles, and water storage and water supply vehicles.

In order to speed up research and development, the Blue Era Shandong Branch came forward to poach various engineering machinery companies in Shandong Province.

After more than a week of transformation, the first-generation equipment finally completed preliminary research and development on February 14.

Although the first-generation equipment is very rough, and many of the equipment are directly pieced together, it can at least be put into trial operation, and then only needs to continue to be improved.

In the pasture of Dongying Dairy Breeding Base.

Three excavators were busy on the saline-alkali land. They dug a bucket into the saline-alkali land and dug a large hole, about one meter deep.

The excavated saline-alkali soil was poured into a muck truck on one side.

The muck truck transported the saline-alkali soil to the tunnel that had been excavated in advance. Under the tunnel was a primary screening truck. The reason why the primary screening truck was parked in the tunnel was to take advantage of the height difference to facilitate the unloading of the muck truck. earth.

The saline-alkali soil is poured into the primary screening truck. After being sifted through the screen, the large rocks and shrubs are filtered to the back of the truck. As the transport truck is sent to the comprehensive recycling plant, the stones will be used as building materials, and the remains of shrubs and the like , then send it to refine the gas to make fertilizer.

The screened fine soil is sent to the desalination truck on one side by a conveyor belt.

When the fine soil enters the desalination truck, the first step is to mix it with water and turn it into thin soil. Then it is sent to the desalination stage, where a large amount of six-cone ball oxygen is injected to extract the salt in the mud water.

After the salt extraction is completed, the muddy water enters the dehydration workshop. About 95% of the water will be separated again. The water is recycled back, and the slightly moist soil is poured into the muck truck in the tail tunnel.

If the previous truck was picked up by a dump truck, the next truck will be picked up by a dump truck.

Standing on the second floor of the container house, Huang Xiuyuan looked around and saw an obvious dividing line at the edge of the pasture.

Ma Changjiang estimated the speed of renovation: "At the current speed, the renovation of these 5,000 acres will be completed soon."

The amount of earth that a twenty-ton excavator can excavate in one shift (eight hours) is usually around 2,000 to 2,500 cubic meters. A fast master can even reach around 3,000 cubic meters.

The depth of the transformed soil layer is about one meter. On average, one cubic meter of saline-alkali soil is produced in one square meter.

One acre is 666 square meters, which means 666 cubic meters of soil need to be excavated. An excavator can level about four acres of saline-alkali land in one shift.

Based on two shifts a day, three excavators excavate 24 acres a day, and it would take more than 200 days to excavate more than 5,000 acres.

Huang Xiuyuan asked: "How did you test the soil after it was improved?"

"All the indicators are in line with expectations. After the land is leveled, we can start planting grass. If we manage it well and plant alfalfa, the yield per mu can be 6 to 8 tons." Ma Changjiang was also very excited.

After he switched jobs from the Shandong Academy of Agricultural Sciences and joined Suiren Company, he felt that he had made the right choice, and even attracted several promising students to join him.

If such a desalination truck is equipped with more equipment, the transformation of these more than 5,000 acres of pasture can be completed quickly.

In fact, without him having to say anything, Huang Xiuyuan ordered the equipment manufacturing company of Snail Industry to start producing desalination trucks, mixing trucks, and primary screening trucks while improving the equipment.

In order to facilitate transportation, Snail Industry is planning to merge a construction machinery company in Shandong Province. Anyway, chassis, generators and other spare parts can be customized for a province with a large construction machinery manufacturing industry, as long as you have money.

Snail Industry only needs to design and produce some core components by itself, and then it can assemble and produce in large quantities.

Of course, some parts need to be further processed after they are purchased, and Snail Industry's unique silicon nano-coating technology is used to improve the strength of the machine.

Suddenly Huang Xiuyuan turned around and said, "Dr. Ma, I plan to establish a northern agricultural research institute in Shandong Province. You should be the head of this research institute!"

"Um..." Ma Changjiang scratched the back of his head and said hesitantly: "Mr. Huang, I have no management experience and I'm afraid it will delay the company's affairs."

Huang Xiuyuan smiled: "Don't worry, Dr. Ma, you don't need to manage the research institute. Management work is the responsibility of the deputy director. You only need to complete the company's projects, or you can prepare your own projects, and then apply to the Research Department for approval."

Ma Changjiang, who had just joined, was still not used to it and was not familiar with the internal operating mechanism of Suiren Company. However, since the chairman had spoken, he could only agree:

"Then I would like to thank Mr. Huang for his trust in advance, and I will do a good job in this research institute."

"Your current task is to complete the exploration of saline-alkali land in Shandong Province. In addition, you can gradually establish a laboratory, focusing on pasture and sweet potatoes for feed."

Ma Changjiang nodded: "I still have many old colleagues at the Academy of Agricultural Sciences, who are engaged in research on pasture and forage sweet potatoes."

"Well, you can act cheaply in this regard. As long as there are no major problems, you can report it to the Scientific Research Department and let them talk about it."

At this moment, Du Jinhua, who was covered in dirt, walked up and said breathlessly:

"Mr. Huang, the initial test is not a big problem. It can be adjusted during production."

Huang Xiuyuan handed over a bottle of warm water: "Thank you for your hard work, I will tell Fu Guo."

After opening the bottle cap, Du Jinhua took a big sip and licked his chapped lips: "Huh, the weather in the north is too dry."

"You have never been to Ice City. The winter there is so cold." Huang Xiuyuan said with a smile.

Several people watched for a long time, and the northwest wind blew for several hours on the second floor of the container house. Except for the locals Ma Changjiang and Xiao Yingnan, several people who came from the south couldn't stand it.

After coming down, Du Jinhua continued to test the prototype.

Ma Changjiang and others also went to prepare for the research institute.

He, Zhang Lei, Xiao Yingnan and others returned to Dongying City because they needed to do another thing.

On the other side, Jiang Hailin, who came from Lingnan, also came to Dongying City with a professional team to join Huang Xiuyuan.

Thank you for your support, and thank you to book friends "Liu Bailiu", "So Cute Is a Blue Child QAQ", "Cold and Unwilling 9406", and "Mysterious Starry Sky" for their rewards (ω｀)
