Polu turned around and stuck his head out to look at Smith, who was standing in the backpack control room on the second floor. He also shouted: "Okay!"
He nodded habitually, only to realize that no one could actually see his movements clearly. He activated the loudspeaker array in the car: "Clear the place! Clear the place! Get ready to leave! Everyone, leave the vehicle! Stay away! Leave the vehicle!"
"
From the perspective of the three people under the car, this strange and huge steel creation has two hammer arms formed by clamping cylinders between cast iron plates erected on the platform at the front of the car. From a distance, the prismatic steel
The drill became sharper, and it lay on the ground, looking like a cricket. Behind the hammer arm was the cab where Polu was, and behind the cab was a huge boiler.
The three people who had jumped off the car circled around at different angles to confirm that no one was forgotten under the tall car. Then they raised their arms to Bolu and made normal gestures. Only then did Bolu
He nodded, but he still stretched out his head to look around the huge machine body, pushed the joystick at hand, and connected the passage from the boiler to the cylinder!
An auxiliary engine made a clicking sound, as if it was a countdown before starting. It drove the heavy flywheel to slowly pull past the dead center.
"boom!"
The steam in the cylinder pushes the piston and drives the flywheel to start normal operation.
"Come up! Come up quickly!"
Polu turned off the auxiliary engine and started to release the steam gear. The eight iron wheels supported by steel beams slowly rotated, driving the huge machine towards the mine.
The mining machine planned to be modified from a tractor chassis has now expanded to the size of a van. Fortunately, Case had some experience accumulated in shipbuilding, so he completed the production of this machine with difficulties. From the experimental ship
The boiler gave it enough steam pressure. During the test run, it was discovered that simply driving could not even increase the energy to the maximum! The cylinder stroke would be greatly increased!
As soon as the mining machine left the small factory, it was noticed by people. After all, there is no possibility that something close to two stories high will not be noticed by the people around it when it is moving on the ground - whether it is sight or hearing.
It is impossible to ignore such a heavy black shadow and such a noisy noise!
It was impossible for this thing to drive into the half-built town anyway. Bolu was going to drive directly through the grassland behind the town! He looked at the people under the car and shouted again: "Keith! You look for it.
I personally go to town and tell them not to panic, this is something we built!"
Watching him run towards the town, Bolu asked them to climb onto the control panel at the back and steer it to make a huge turn awkwardly, driving all the way from the green wilderness towards the mine, on the beautiful turf.
It left deep tooth marks caused by the friction-increasing steel bars on the steel wheel!
"Full power! Hahaha! It's so cool!"
Polu looked at the ground on both sides. He should be reaching a speed of 15 kilometers per hour. The speed was not fast, but the torque was huge. The road to the mine climbed slowly, but the driving was very smooth. What I used to find annoying was the powerful cylinder.
The slight vibration caused by the pulling now makes Bolu feel relaxed and happy!
The vibrations coming from under the body, the bang bang of the cylinder, the friction of the gears and the passionate steam jets were mixed together. It was rumbling and roaring wildly. On the way to the mine, look at
Seems like slow and unstoppable progress!
People in the town flocked from construction sites and factories to the road where they could see this machine moving forward. They raised their hands and cheered. They already knew that this was a new tool made by Bolu. They knew that there was more or less something belonging to it.
own contribution!
The most important thing is that although this machine is tall and noisy, it is different from the gorgeous, powerful, and mysterious powers of the mages. They have seen its prototype, its predecessor, and its manufacturing process. This machine is their
Something that understands the principles! According to the little manager's habits, soon, this is what they will make with their own hands!
It arrived at the mine after some crawling. In order to remind the knights of its arrival, Bolu blew the whistle, but it caused some chaos in the bugbear team! The terrifying roar of this metal monster made the bugbears
They were trembling with fear, and finally the knights used sticks to silence them.
Leonardo came over and jumped into the cab without waiting for the mining machine to stop: "Hey! It's only two days as promised, but you delayed it again! How many days did you delay this time?"
Bolu blushed: "What's the delay! Can we call it a delay when it comes to engineering projects?"
He patted the dashboard: "Look at this big guy, how powerful it is!"
"Whether it's great or not, you still have to give it a try. You've already driven up here, why don't you give it a try?"
"Come right away!"
Polu controlled the mining machine again and came to a place where there was no one. He pulled down the joystick, opened the small door, and said to Leonardo: "Let's go up there."
"This? There are two more floors?"
"Well, one person is really busy. The mining control part is upstairs, and the three of them are up there."
The two climbed up the narrow pedals to the second-floor backpack-type operating platform. Three people were squeezed into the operating platform and there was no room to turn around. Polu had no choice but to shout to them: "Start mining!"
.
The steam engine makes so much noise that I can't even hear it without shouting.
The people inside also shouted in response: "Okay!"
By the time the two returned to the cab and put on the slowly retreating reverse gear, the cannons in front had already begun to sound. The steam that had been ready to go surged along the pipes. They rushed towards the cylinder and pushed the piston, which was as thick as two thighs.
, the heavy and dark polygonal steel drill was suddenly lifted up by the piston and pushed off the ground! Then, driven by the steam distribution mechanism, it smashed hard towards the ground!
"Boom, boom, boom!"
The steel drill hit the ground, and the dense and dull impact sounded rhythmically. This sound seemed to penetrate into the body, making everyone's heart beat faster.
You can't actually see clearly the part being struck from the console, but after just a few hits, the sound of crushing was mixed in with the noise. The mining machine slowly backed up, and the ground that was intact just now has now been exposed on the ground.
In a line, it looks like the ice on the river in winter is cracked and arched!
Leonardo shouted at the top of his lungs: "The effect is very powerful! It's much faster than manual mining! What the hell did you install!"
"Remember the old experimental runabouts?"
"Remember! Why bring it up!?"
"This is its boiler!"
"What!"
"It's the same power as a runabout!"
Leonardo opened his mouth, seemingly shocked by Polu's madness!
At the beginning of this transformation, Polu, who was pursuing high boiler pressure, directly installed the heat pipe boiler removed from the experimental ship on the vehicle. Based on current experience, he wanted to keep the double-action steam hammer being cast strong.
The powerful piling action cannot be supplied by the tractor's original boiler.
But what is embarrassing is that once the boiler, which is almost as big as the vehicle body, is installed, the tractor directly turns into a sprinkler truck. Looking at this sprinkler-like machine, Polu seemed to hear a pleasant melody in his ears.
"Doesn't it look so uncomfortable on the model?...I don't think so. There is no room to install other things like this."
Case, a supporter of directly manufacturing the new chassis, put forward his suggestions for modification at this time: "How about we make the boiler smaller?"
"This is a machine that uses steam pressure to crack ore. It's not like you haven't seen an ordinary boiler just now. It can't supply the required steam pressure at all. The action of the steam hammer is weak and the pressure will return to zero after a few minutes. This
What do I need it for?"
Boru shook his head, refusing to lose motivation.
"Then we have no choice but to expand the chassis."
There is no doubt that this time the work will be delayed again.
At first, the chassis was just enlarged, and the workers who were filling the boiler with water caught Polu's attention while chatting beside the car: "The water consumption of the boiler is very high now. In the past, the water tank was filled every two hours. Now,
The boiler is running all the time, and you have to add water after half an hour. This method of using a steam hammer is really wasteful of water."
"I didn't realize before that the steam was sent directly to the machine. This thing can drink all of us's fresh water in a day, right?"
"It's hard to say, but all the tractors combined should be about the same."
"What if there are more tractors in the future and the water in that river is not enough? I don't think the river is very deep."
The workers were talking unintentionally, but Bolu, who was thinking about how to farm every day, heard that he was interested, and he started thinking about it again.
"What they said makes sense. Now that we are on an island, do we need to save some water? This single expander removed from the experimental ship is really consuming water! But will it be used in that small river later?
Build a reservoir?"
However, the reservoir is still far away, and the water-drafting steam hammer is close to practicality. After all, the mining machine cannot go as far as the locomotive running on the track, and it can pull a water tank alone to supply its own water.
How about making a condenser? After all, the water consumption is so high that there must be a dedicated person to take care of the water filling activity.
At the beginning, he thought about making a simple water tank according to the normal model. However, when Case saw it when he passed by, he thought it was something else: "Little manager, why are you making another boiler?"
"Boiler? This one doesn't generate heat, this one recovers water vapor!"
When he encountered something he was interested in, Case simply squatted down:
"Steam recovery? I don't quite understand?"
"Did you know that if something blocks the steam from the kettle, it will form water droplets?"
"I know."
"Then this one is about the same. The metal pieces inside can conduct heat away quickly."
"Then what?"
Polu took out a steam-powered fan and pointed the direction of the air inlet.
"Put this on, and then blow the air against the exposed metal piece here. Let it be carried away by the wind! Now that the temperature is so low, the effect must be good, and a lot of water should be recovered from the steam!"
"The colder the better? So these tubes are full of cold water?"
"Um."
"Isn't it similar to the structure of a boiler? One is hot and the other is cold?"
Bolu was stunned for a moment. He paused and put down the fan in his hand: "What did you just say?"
"One has fever and the other has chills?"
"Yes! Chills!"
"Haha, I thought of it! You little clever guy! Now I don't have to worry about the water tank exploding! Come and help me! Find two iron plates and copper wires!"
