"There is gold?" said Fan Yang and Missing a Sect in surprise.

They grew up in this area, and they had never heard of gold panning in this river.

Zhao Guangming picked his head and thought for a while: "No, this river is winding and winding, how can you figure out the direction? Could it be a tributary of the Min River? No, is it Luding, or Aba? Whatever, go and look for it, you will meet our peers." ”

Saying that, Zhao Guangming urged: "Get in the car and get in the car." ”

"Where?"

"Go into the city, take me to the river. ”

"Isn't it okay to go down here? Fan Yang said.

"What do you look at, look for Binjiang Road, go around along the river, and I'll see if there are any peers. ”

Seeing the joy of hunting for a while, Zhao Guangming put his hands behind his back, his expression became arrogant, and he urged again and again, Fan Yang was also interested, and drove into the city.

Neijiang, as its name suggests, is a riverside city, the water surface of the Tuojiang River basin in this section is wide, just ask someone, it is easy to find Binjiang Road, come to a square called Dazhouba.

At this time, it was almost noon, and the three of them found a restaurant to eat fish, and there was a catfish from the Qiuxi River here, which was quite famous, and there were restaurants with the catfish signboard of the Qiuxi River everywhere.

The fish is very cheap, the three of them ordered two, and the taste is quite good, spicy and fresh.

A middle-aged boss on the counter was holding a calculator and settling accounts there.

After eating, Zhao Guangming picked up Fan Yang's cigarette case, handed out a cigarette to the shopkeeper, and asked, "Boss, where did your river come from?"

"Isn't there a memorial arch outside, isn't it all written on it, Longmen Mountain Range, you go and see it yourself." The boss replied.

"Longmen Mountain Range, Wenchuan, Oh......" Zhao Guangming looked clear: "That's from Dujiangyan, are you more than Wang Baduo in this river?"

"Many, you're talking about Jiang Tuan, there are often people who hit, you want to eat fresh, guard by the river, there are people who specialize in using poles to catch fish balls, two or three yuan a catty. ”

"You can buy some, this river is so big, you can drive a boat, right?"

"I can open it. ”

"What about the river sand? Do you have sand miners here?"

"You walk along the river, there is a lot of sand. ”

"Thank you. ”

After paying the bill, the three of them came to the square and found the archway, and there was a relief carved on a landscape stone outside, on which was a picture of the river, and there was a text description next to it.

Sure enough, it also flows down from the plateau, originating from the Jiuding Mountain in the Longmen Mountains, with a total length of more than 600 kilometers, passing through several prefecture-level cities, and finally flowing through Luzhou to join the Yangtze River.

"Let's go, go down Binjiang Road. ”

I drove along Binjiang Road for a while, and the road was impassable.

Binjiang Road is connected to the breakwater, the water level is not high at this time, standing on Binjiang Road, there is a drop of five or six meters across the water.

has driven to the end of Binjiang Road, a railing in front, Zhao Guangming got out of the car, held on to the railing, and looked downstream.

However, he found that on the river beach not far downstream, a yellow sand road about five or six meters wide had been widened, and a large truck swayed over on the road.

The car was loaded with a cart of river sand.

A triangular spire was piled up on the carriage.

"Let's go down and have a look. ”

The three of them locked the car door, slipped down the breakwater, and crossed the river beach to the yellow sand road.

As soon as Zhao Guangming stepped on the road, he picked up a handful of sand from the ground, which had just fallen from the sand truck, and was still wet, pinched it in his hand, looked at it for a while, and shook his head.

took the two of them along the yellow sand road, walked for more than ten minutes, turned a corner, and their vision suddenly opened up.

I saw two sand mining ships on the surface of a bay in front of me, several large rocker arms on the ship were in the air, a hanging basket was below, and several conveyor belts were erected.

The sand excavated by the sand mining ship is transported from the conveyor belt to the shore and piled up into several large and small dunes.

In the next few sheds, the roar of machines could be heard inside.

"Look at it, look at it, what did I say, there are indeed peers. ”

Zhao Guangming smiled contemptuously and said.

"You mean, this sand mining ship is gold panning?" Fan Yang said in amazement.

"Definitely, there is no sand mining without panning for gold. ”

The three of them stood on a high place, the sheds were just made of color steel to build a rough fence, and the machines inside were all open-air equipment, and from a distance, there were dozens of oil drums piled up inside.

"Look, the one with the bucket is the wheel bucket sand washing machine, the sand and gravel are selected, and a chute has been modified over there, isn't it the same as our water slide trough, but it's just a machine to tao, rough, but it can't control the large amount, there is a crusher over there, which is also modified, and a filter and a vibrating screen are added. Zhao Guangming pointed and said: "There is not even an excavator, so I have a small fight." ”

There was disdain in his eyes.

"You say they're really panning for gold?" asked excitedly, "Good guy, such a big scene, how many gold bars do you have to pan this day?"

"What is this? It's all laymen, you don't see us there, let's go, there's no looking, but that's it. Zhao Guangming said that he was about to leave.

"Don't worry, I don't think it's complicated when I look at his equipment, right?" Fan Yang observed for a while, his vision of things was different from the lack of a subject.

I don't know anything without a course, and when I see such a big stall, I just feel extremely complicated.

But in Fan Yang's eyes, it's really nothing, the equipment can be said to be quite simple, although he doesn't understand the machinery, but he still knows a little, just two sand mining boats, the structure inside can also be imagined, the big deal is a lifting digging bucket, this is estimated to be the most expensive, but for their own operation?

As you can see, it's just a crusher, and the purpose should be rough selection, with a certain amount of grinding, and then filter out the fine sand.

After that, there is the sand washer, like a waterwheel, while washing, with a waterwheel-style rotary funnel.

The washed out fine sand is lifted onto a conveyor belt.

The conveyor belt is then conveyed to a nearby chute.

The chute has a certain vibration function, and then it is still rinsed with water.

This preliminarily realizes the industrialized, semi-automated gold panning process.

But after observing for a while, new discoveries were made.

"Brother, if I'm not mistaken, you said that this is a layman, and their gold panning is probably not the main purpose, it should just be by the way, right?" Fan Yang said.

"Hey, yes, you can see that?"

"Well, just speculation. ”

"Yes, these are laymen, how can there be no gold mining in sand mining, no panning, isn't it a pity, but the gold content of this river section is small, and it is useless to want to make it bigger, you don't see what kind of river section this is, alluvial bed, how much gold can there be, and there are more sedimentary beds. ”

"What do you mean?"

"Isn't this simple, they pick the river beach, that is, the water flows down, the waves on both sides, the sand on the river beach, and there is no backwater section, where can the gold sink down, they are all laymen. ”

"What about the sedimentary bed?" Fan Yang asked again.

"Let's dig that pit, isn't it a sedimentary bed?"

Zhao Guangming looked at Fan Yanghe and the lack of a door, his eyes were much more sincere, and most of his vigilance was gone.

I started to loosen my mouth slowly.

"The sedimentary bed, this depends on the water level, there must be blocking, there must be karst rock under the riverbed, the river surface should not be too wide, pay more attention to it, I will tell you slowly in the future, I am gone, I really don't look at it. ”

"Wait, what I want to say is not this, brother, his set of equipment, it looks complicated, in fact, I have seen a rough idea, they are mainly sand mining, supplemented by gold panning, so the sand mining ship and the crusher, for us, are dispensable, right?"

Zhao Guangming glanced at Fan Yang in surprise: "You kid, why are you so accurate?"

"It's not difficult, which means that if it's gold panning equipment, the most important thing, the sand washing machine, and the vibrating chute, it's okay, right?"

"If you want to say that, you can say it. ”

"Then these two pieces of equipment, how much money can be paid, we can completely complete the set. ”
