Bright Sword: Starting from the Improved Grenade

"Chief, the parts for the new pot-carrying machine are ready."

Li Yuncai entered the tent and said to Zhao Tianyang who was concentrating on drawing a blueprint.

"Come on, let's go put it together."

Zhao Tianyang was a little excited. After the cylinder exploded the day before yesterday, he spent a day repairing the tractor.

Then he immediately enlarged the pot-carrying machine drawing in proportion, preparing to make a pot-carrying machine with more horsepower.

Soon the two arrived at the engine factory, where six workers were already waiting.

These people were the ones who had followed him to test the tractor last time. He kept them and made them workers in the engine factory.

"Chief, you're here!"

Several workers came forward happily. They were very excited. Although they were all workers, only the workers in the engine factory could ride on tractors.

The workers in the arsenal and sulfuric acid plants are so envious of this.

"Ok!"

Zhao Tianyang nodded: "Let's start assembling!"

Zhao Tianyang had no idea how many pot-carrying machines he had assembled. Although this one had become much larger, its structure had not changed.

With the assistance of several workers, it only took three hours to successfully assemble the largest pot-carrying machine currently in the arsenal.

"Go and fetch that 272-pound piece of iron, and we'll calculate the horsepower of this pot-carrying machine."

Zhao Tianyang gave instructions to several workers.

Because there were no professional tools to measure horsepower, Zhao Tianyang's method of testing horsepower was always to imitate Watt and use the power of a horse to test the water-lifting capacity of a steam engine.

That is to connect a 272-pound iron block with a rope and the flywheel outside the pot-camel machine, and calculate the horsepower by how far the pot-camel machine can pull the iron block in one minute.

"Chief, it's tied up."

Four workers worked together to move the heavy iron block in with a rope, and then tied the iron block and the flywheel together with the rope.

Finally, the test was completed and through calculation, it was found that the pot-camel locomotive reached 20 horsepower, which is also the maximum horsepower of the pot-camel locomotive. If it is larger, it can only be equipped with a steam engine locomotive.

"Put on the tracks, transmission, steering, bed, and seats. Let's drive out and test them using the sand pulling method we used the day before to see the specific data."

After calculating the horsepower, Zhao Tianyang was full of confidence and started assembling the tractor with his men.

"Chief, I'm here to help too. Let me drive the car later!"

Li Yuncai's eyes lit up and he quickly requested.

"Row."

Zhao Tianyang patted Li Yuncai on the shoulder and handed him a wrench: "Here is the wrench for you. Go under the pot camel machine and install the drive shaft and steering device."

"Just pretend!"

Li Yuncai took the wrench and crawled under the pot-carrying machine.

"The screws are tightened, and the transmission shaft is tilted. Adjust it quickly."

In the afternoon, Zhao Tianyang lay on a chair, smoking a cigarette while directing Li Yuncai and others to install the tractor.

"Section Chief, you don't even come to help. You just smoke and gossip!"

Li Yuncai wiped the sweat from his head and complained dissatisfiedly.

"Hey, I'm training you. If I, the section chief, have to personally install a tractor, what use are you guys?"

Zhao Tianyang smiled as a matter of course and said, "Hurry up and work, try to finish it before four o'clock, then pull it out for testing, and try its night travel capability by the way."

"understood!"

Several people answered in unison, among which Li Yuncai's voice was the lowest.

At four o'clock in the afternoon, with the constant encouragement of Zhao Tianyang, Li Yuncai and others finally assembled the 20-horsepower tractor on time.

"Section Chief, can we go out and do the experiment now?"

Li Yuncai came to Zhao Tianyang with great interest and asked.

"Ah."

Zhao Tianyang nodded: "Have someone fill up the water and coal, and preheat it. Don't forget to hang the calcium carbide lamp that we recently made on the hood."

"okay!"

"Wait, go change your clothes first, and then wash your face. There is not a single clean spot on your body."

Li Yun was just about to leave to do something when Zhao Tianyang stopped him and kindly reminded him.

"Oh, oh, I'll go right away!"

Li Yuncai looked at his hands which had turned pitch black and quickly replied.

Because it took an hour and a half to preheat the boiler, it was dark when Zhao Tianyang and others arrived at Dahe Village after bringing the guards at the door and the village chief.

"Section Chief, you figure it out first. I'll go find someone to cook something for us!"

Because they had not eaten dinner, everyone was very hungry when they arrived at Dahe Village. So the village chief volunteered to go to Dahe Village to find food and asked people to work overtime to load river sand.

"go Go!"

Zhao Tianyang waved the hand holding the wooden stick and said nonchalantly that he was busy calculating the speed of the tractor!

"How's the section chief? Any results?"

Li Yuncai, who was holding a calcium carbide lamp for lighting, asked.

"Almost. Compared with last time, we almost shortened the time by two times this time, reaching 15 kilometers per hour."

Zhao Tianyang threw away the stick and patted the dust off his hands: "By the way, I asked you to check how much water and coal are left in the boiler. Did you check?"

"Look, there's more than half of the water and coal left. We only used a small portion this time."

Li Yuncai replied.

"It seems that according to conservative estimates, the range of our tractor can reach about 150 kilometers!"

Zhao Tianyang was very satisfied. Although this 20-horsepower tractor consumed more materials than the 15-horsepower one, it was insignificant compared to these performances.

Next, let’s take a look at its ultimate load-bearing capacity.

"Chief, I'm back. The village chief has made corn paste and steamed wowotou for us at home. Let's go and eat!"

At this time, the village chief ran back and said to Zhao Tianyang.

"Row."

Zhao Tianyang nodded: "Everyone is hungry, let's eat first and then test the performance of the tractor!"

After having dinner at the village chief’s house, Zhao Tianyang and others, as well as the workers from the Dahe Village sand field, came to the sand field.

After lighting a fire around, they began to test the tractor's load capacity using the same method as last time.

After a while.

"Okay, just unload another 1,000 kilograms of river sand."

Hearing Li Yuncai's familiar words, the middle-aged man was not angry, he was even a little expectant.

Because he cooperates with these people, he will be able to smoke foreign cigarettes later. He used the cigarettes he got last time to exchange for many things!

"The village chief still follows the old rules. Give the cigarettes to the brothers to share."

Zhao Tianyang took out a pack of incense and handed it to the village chief.

"okay!"

The village chief took the cigarette, walked up to the middle-aged man skillfully and started talking to him. Soon, the village chief climbed up the sand pile amid the middle-aged man's smiling greeting.

"Turn on those two special carbide lamps."

Zhao Tianyang gave instructions to Li Yuncai who was driving.

Because there were no high-power bulbs for lighting, Zhao Tianyang used calcium carbide and water to make several special calcium carbide lamps.

The spotlight covers made from the collected broken glass allow the two calcium carbide lamps to illuminate a range of fifteen meters in front.

"okay!"

Li Yuncai jumped off his seat, came to the front of the car, and lit two calcium carbide lamps with a tinderbox.

In an instant, the dirt road that was pitch black just now was illuminated. Although it was not as bright as during the day, it was enough to illuminate vehicles.

"Let's go, let's go!"

Li Yun returned to his seat, shouted, and started the tractor.

Although they went to Dahe Village later than last time, thanks to the powerful power of the tractor, they came back earlier than last time.

More importantly, there was no problem of cylinder explosion this time.

After placing Hesha and the village chief in Chiyu Village, Zhao Tianyang and others returned to Huangya Cave.

After getting off the car, Zhao Tianyang said in a good mood: "This test is considered a complete success. Our engine factory will produce this 20-horsepower camel engine in the future."

"Don't be idle these few days. Produce a few more and then add iron sheets to make armored vehicles. I'll give you the blueprints tomorrow!"

After saying that, he leisurely returned to the tent and prepared to rest.
