Chapter 496: I am the eldest sister in the family 12

Some are happy and some are sad. The village leaders are happy about the stone transportation, but the villagers may not be.

Although the work in the quarry is physical and harder than ordinary farm work, the work points are high.

Jiang Lan saved effort and increased efficiency by doing this, but everyone was unemployed.

"Look, what happened? What are we going to do now?"

"That's right, we could have worked longer, but now it's fine."

The two men sat in the aisle angrily, and when they saw Jiang Lan passing by, they both rolled their eyes, indicating that they disliked her very much.

Jiang Lan smiled and didn't care too much.

She walked around the quarry and then found the leader of the production team.

Jiang Lan had just made a contribution, and the captain's attitude was also good, smiling.

"What's wrong? Are those old guys in the mountains bullying you because of their seniority? Don't bother with them, they just know how to live a lazy life every day."

"Captain, how could that be? We are all from the same village, and they are all good people."

"It's good that they didn't bully you. If they bully you, tell me, I promise I won't let them off."

These words were just talk, and Jiang Lan didn't take them seriously. She soon asked about other things.

"Captain, why doesn't our quarry have any equipment? I see that everything is dug by hand. The stones are big and small, and it's not lucky. Are they used to make works of art?"

The captain said speechlessly: "What works of art? Our stones are used to support national construction and to build bridges and roads."

"Then wouldn't it be great if the stones were crushed?"

"It would be great, but we don't have machines. Our village will have a tractor in a while, and we can transport the stones out. It is said that there are things like crushed stones in the county."

Jiang Lan asked in disbelief: "There are really no machines in our village? How did we break such big stones in the past?"

The captain thought for a while and slapped his head.

"Now that you mention it, I remember that there is indeed a big machine in our village, but it has been broken for a long time. We asked several technicians from other provinces to fix it, but they couldn't fix it, so it has been kept in the warehouse for many years."

"Captain, I like to study machines. Can I take a look?"

"You little girl, why do you keep..."

The captain was a little impatient, but when he saw Jiang Lan's expectant eyes, he softened for a moment.

"Forget it, I'll take you to see it."

"Thank you, Captain, you are so wise."

Jiang Lan flattered him so much that the captain walked with his head held high.

"It's this machine, a stone crusher. It was used to crush all the stones in the quarry. But who would have thought that it would break down after just a few months of use."

The machine was covered with thick dust, and it was obvious that it had been idle for a long time.

"Captain, can I give it a try? I think I can fix it."

The captain certainly didn't believe it, but he didn't hit her confidence directly, but said: "This is something that the technicians in the provincial capital haven't been able to fix. If you really have the ability to fix it, then I have to remember your great merit."

"Captain, then I'll give it a try. Anyway, I won't suffer a loss if I can't fix it."

"Okay, there's nothing valuable here anyway, just this piece of iron. I'll give you the key, come over by yourself."

"Thank you, Captain!"

Jiang Lan got the key to the warehouse as she wished, and soon started the second step of the plan.

At first, she thought the crusher here was a huge machine used to break rocks, but it turned out to be a small machine about 2 meters high and 3 meters long.

Jiang Lan checked the machine and decided not only to repair it but also to make a simple modification to upgrade it.

She decided to optimize the original vertical compound crusher with external fine crushing technology so that it can be used to crush some relatively hard stones.

After the stone falls into the high-speed rotating impeller, it collides with the other part of the stone that is diverted around the impeller in an umbrella-shaped form at high speed under the action of high-speed centrifugal force. After

the stones collide with each other, they will form a vortex between the impeller and the casing, and then collide and rub against each other many times to be crushed.

In addition, Jiang Lan also designed a screening device to control the size of the crushed stone.

The crushed stone is discharged directly from the bottom, forming a closed loop for multiple cycles, thereby controlling the size of the finished particles.

If the materials are better, and the vulnerable parts are made of high hardness, high toughness, and multi-alloy wear-resistant materials, the service life can be increased several times.

Unfortunately, there is no such condition at present, so we can only make such a relatively low-cost crusher.

This thing is not electric, and the power depends entirely on diesel.

Jiang Lan couldn't find diesel for a while, so he had to go to the production team leader again.

Knowing that Jiang Lan had repaired the antique that had been in the warehouse for a long time, the team leader was also surprised, so he half-believed and half-doubted and went to see it.

Halfway through the walk, they happened to meet the big team leader, so the three of them went together.

"Can this thing really be repaired?"

The two team leaders circled around the machine for a long time, but couldn't see what it was.

"Just connect the diesel and try it out, and you'll know. This machine won't lie. If it can move, it can move, and if it can't move, it can't move."

This made sense, and soon the production team leader went to fetch a bucket of diesel and poured it all into the machine.

Jiang Lan was not idle either, and directly moved a fifty-jin stone over.

"Be careful..."

The team leader was also shocked to see a girl moving such a big stone.

The production team leader knew that she was very strong, but advised: "Don't worry about this girl, her strength is stronger than three or five strong men in the village."

"So strong?"

Jiang Lan put the stone next to the machine without blushing and panting, and asked: "Captain, is the oil full? I have to start working."

"Okay, okay, you do it."

The two men made room for Jiang Lan, and she turned on the switch and pushed the whole stone in.

"Will this work? This stone is too big, right? I remember when we bought this machine, the technician said that this thing can only crush stones under 20 kilograms."

"Let's try it, let her try it, young people always..."

Before the captain could finish his words, he heard the loud sound of the machine running, and soon saw crushed stones coming out of the exit.

"It's amazing, it can really be broken."

"Ah, this piece of iron is really good."

"With this machine, we don't have to go to the county to line up, we can just pack and sell this broken stone to..."

"Ahem, let's talk about this at the meeting, don't talk about it for now."

The production team leader was stunned for a moment, and quickly calmed down.

"Oh, Jiang... Jiang Lan, right? Why don't you go back first? You will definitely be rewarded for this, don't worry."

Jiang Lan also knew that it was not appropriate for him to be here now, so he withdrew very tactfully.
