Bright Sword: Starting from the Improved Grenade

"Section Chief, you're out!"

Zhao Tianyang had just walked around the tent twice when Li Yun came over with a notebook.

"What, is something wrong?"

Zhao Tianyang glanced at him and continued walking.

"It's like this. Yesterday, all the arsenals basically completed their preparations for the start of work and have resumed production today. However, the materials we purchased are only enough for us to produce at full capacity for six days."

Li Yuncai replied.

Hearing this, Zhao Tianyang stopped, took Li Yuncai's notebook, and looked through it: "How many weapons and equipment can those materials produce?"

"According to the reports from the various factory directors, the arsenal can produce about 60 Taihang Type rifles, new pull-type black powder grenades, three Dinglong grenade launchers, and one Taihang mortar."

"Weapons like the Taihang 70-caliber cannon, the Taihang 20-caliber shotgun, and the Elmwood cannon all have to be abandoned for the time being because there is not enough material."

"The propellant factory can produce about 500 kilograms of black powder, kilograms of smokeless propellant, and kilograms of imitation Judison explosives."

"The sulfuric acid plant can produce about 100 kilograms of sulfuric acid, 32 kilograms of ammonium nitrate, and 10 kilograms of TNT explosives."

"The radio factory can probably produce ten radios."

"The ironworks can produce about two tons of various types of steel."

"At present, we still lack an alcohol factory, a paper factory and a ceramic factory, which have not been built yet."

"Where are the bullets and shells?"

Zhao Tianyang closed the notebook and asked, "One is that the chalcopyrite has not arrived yet, so there is no material. The other is that the semi-automatic bullet production line made by Comrade Liu Ding is not ready yet, so Director Shen has not planned the production tasks of artillery shells and bullets."

"Ah."

Zhao Tianyang nodded and said, "Let them produce first, and when the weapons and equipment are ready, we can take them to the boss and exchange them for money."

"I've been here for so long, and I've been asking them for money all the time. This time I won't be able to ask for money unless I bring weapons and equipment with me!"

“Everyone thinks so too, and they are all working hard!”

Li Yuncai echoed.

"That's good."

Suddenly Zhao Tianyang thought of something: "By the way, are all the parts I asked you to prepare ready these days?"

"It has been prepared long ago and is stored in the newly built engine factory."

Li Yuncai replied.

"Come on, let's go take a look!"

As he spoke, Zhao Tianyang took the lead and walked towards the blast furnace area.

The newly built engine factory is built with thin wooden boards and is about 500 square meters in size, which looks a bit small.

However, the manufacturing of engines is mostly completed outside the factory, and this factory is mainly used to store materials, so 500 square meters is more than enough.

When you open the door, what comes into view is a pot-carrying machine that is more than 2 meters high. This is the largest pot-carrying machine that Zhao Tianyang has currently manufactured. The specially enlarged cylinder provides this pot-carrying machine with a powerful power of 15 horsepower.

Next to the pot-carrying machine, there are many parts of various shapes. These were all made by Li Yun using sand molds at the instruction of Zhao Tianyang.

There were cast iron gears, gears with connecting rods, drive shafts, long steel plates, universal joints, and several tank wheels and tracks.

After Zhao Tianyang checked and found that there was no problem with the parts, he began to assemble them. He first used the drive shaft and gears to change the crank connecting rod to output power.

Change the reciprocating motion into circular motion, and then install tank wheels and tracks.

In this way, the pot-carrying machine can be started by itself. Then Zhao Tianyang found a welder and asked him to weld a suspended driving seat on the pot-carrying machine.

After these are completed, the control system will be installed with the driver's seat as the center, because the pot camel is equipped with tracks.

So Zhao Tianyang chose to use various gears and connecting rods to make a differential, so that the tracks on both sides would produce different speeds to complete the turning.

After installing the steering system, Zhao Tianyang used universal joints and drive shafts to connect the differential and the steering wheel, so that he could steer by turning the steering wheel.

Of course, there is no power-assist system, and steering is entirely based on brute force.

After solving the movement and steering problems, the only problem left was how to control the speed of the pot-carrying machine. Because there was no gearbox, Zhao Tianyang chose the simplest and most brutal solution, which was to directly control the steam valve.

He used the amount of steam entering the cylinder to control the speed of the boiler machine. He asked the welder to weld an iron ring on the steam valve. As long as the driver used an iron hook to hook the iron ring, the amount of steam in and out could be controlled.

After solving the speed problem, the only thing left to do is to install the truck bed. This is relatively simple. Just weld a truck bed with iron sheets and iron rods, and then connect them to the pot-carrying machine.

Finally, after a whole week and various adjustments and modifications, Zhao Tianyang finally made the pot-camel version of the tractor.

"Wow, this is a tractor. It looks pretty big!"

"Yes! With it, we no longer have to use carts to transport ore!"

The workers in the blast furnace area all gathered around with great interest to watch the excitement.

"Chief, why don't you try it now and see if it can be started?"

Li Yuncai was itching to try one out. He had been helping Zhao Tianyang these days. He had participated in the construction of this tractor from scratch. Now he couldn't wait to sit on it and try it out.

"Okay, let's give it a try."

Zhao Tianyang agreed.

"Quick, add water and coal."

After getting consent, Li Yun quickly gave instructions to the workers nearby.

After the workers filled the boiler with water, Li Yun came to the front of the boiler carrying machine and threw a match into it personally. Soon the coal in the combustion chamber was ignited and began to emit heat.

An hour and a half later, the boiler of the pot-carrying machine began to make noises and wisps of steam began to come out.

"Section Chief, let me help you test whether it is safe or not!"

After saying that, Li Yun sat down on the driving seat, picked up the iron hook on the driving seat, and hooked the steam valve in front.

Instantly, water vapor rushed into the cylinder, the piston began to move, the power was transmitted through the connecting rod, and the pot-camel tractor began to move slowly.

"It's moving, it's moving!"

Everyone became excited and started to follow the tractor.

As more and more steam was produced, the speed of the boiler-carrying locomotive and tractor became faster and faster. The small blast furnace area was no longer enough for Li Yuncai to move. He turned the steering wheel and drove towards the hillside leading to the arsenal on the mountain.

It can be clearly seen that the pot-carrying tractor, which the workers had to run to catch up with, slowed down to half its speed after going up the slope, and the workers could catch up with it by just walking fast.

"It's a bit slow."

Zhao Tianyang frowned.

You know, Li Yuncai opened all the steam valves, but he still had a hard time climbing the slope.

It seems that after the modification, the original 15 horsepower is not enough, and we have to continue to increase the horsepower.
