Chapter 239: Band Saw Machine (Second Update, Asking for Support)

How strong is the destructive power of the Great Ming Speaker, represented by the matter?

Although Shi Yiwen has not experienced it, it is certain that even if Zhang Juzheng is a strong appearance, there is not much way to do it for those people, otherwise there will be no "love-grabbing" turmoil.

Even, to a certain extent, those speech officials are the "keyboard warriors" of later generations, and they never consider the consequences of their words when they are not responsible for their words, anyway, in their opinion, "doing things horizontally and vertically is a sin; The horizontal and vertical of watching the play are reasonable. ”。

For such people...... Don't say that there is a reason, that is, they can pick out the thorns in the eggs, if they have a reason, then they must not let people lose three layers of skin?

"My grandfather asked me to come, just to ask Zhiyuan two words - can the coal mine meet the needs of the capital?"

Zhang Weiliang's question made Shi Yiwen silent for a moment, and then said.

"Yes!"

Yes, in the past few months, the coal mines have been undergoing technical transformations, and the coal miners have been learning new coal mining methods, albeit by hand, but with blasting and other methods, the new mines will produce several times more than in the past.

"Is it really possible?"

"Don't you believe me?"

Shi Yiwen said with a smile.

"Now the mine has begun to use the wall coal mining method, and the use of "cannon mining", the pit is also laid with wooden rails, can directly use horses to pull the mined coal out of the pit, the new mine can be planned to produce up to five ...... 10,000,000 catties. ”

Shi Yiwen, who originally wanted to say 50,000 tons, said that 50,000 tons is only this year's output, and the output will further increase in the future, maybe in a few years, it will reach a scale of more than ten or even three or four hundred thousand tons.

Even in a decade or twenty, the output here may even reach millions of tons, who knows? As long as there is market demand here, the output of Mentougou coal mine will continue to increase, after all, there are not many high-quality anthracite mines like this.

"That's good, now it seems that the key is transportation, the main thing is to transport the coal out of the mountains."

Zhang Weiliang breathed a sigh of relief, and then said quite eagerly.

"It seems that it is still the same as I thought on the road, the key is that this fast road for transporting coal, how long will it take to build it? Why don't we go over and have a look now? ”

When Shi Yiwen and Zhang Weiliang came to the road construction site, they could see that the construction site was very busy, full of busy laborers, and the railway was built in accordance with the road construction standards of light railways, which is actually a rammed earth roadbed without stones.

"Owner, in fact, if the gravel is paved, maybe the effect of the road will be better, we have paved the gravel on the roadbed along the mountain on the Mentougou side, and the effect is very good."

In the face of Shi Yiwen's inquiry, Li Ruizhi suggested directly.

"Of course, the gravel roadbed is good, but the cost of gravel is high."

Shi Yiwen said with a smile.

"Without a stone crusher, it doesn't seem realistic to spread the gravel roadbed. The gravel was blasted out when the mountain was opened, and the amount was not large. ”

"In fact, there is a lot of idle coal gangue on the mine, and when it is mined, it is very broken, so maybe you can consider using it."

Without waiting for Li Ruizhi to finish speaking, Zhang Weiliang said.

"It's not important now, it's when the road will be built."

Looking at the fast road along the wooden track that runs along the earth, Zhang Weiliang's tone seemed a little anxious, he knew that for the outside world, this Jingxi Road mine belonged to the British government, if it could not be repaired as soon as possible, it would be the British prince who would be impeached at that time, and it would be his grandfather who would be impeached.

"Now only the road and bridge on the side of Lugou Bridge have not been completed, but it will be completed by the end of this month at the latest, and there are still more than ten miles of tracks along the way that have not been paved, mainly because the wood factory cannot supply the rails."

"Carpentry? How could there be a problem over there? ”

Shi Yiwen asked suspiciously. There shouldn't be any problems there.

"What? Can't process wooden rails? ”

When he came to the carpentry factory, Shi Yiwen finally knew why the wooden rail could not be processed - manpower, here he finally saw the manual saw, hundreds of carpenters with large saws saws from Liaodong hardwood sawed into the required 15 cm long and wide wood squares......

Negligence!

Shi Yiwen immediately understood the reason, he didn't even hesitate, and said to Zhang Weiliang.

"Let's go to the ironworks."

After returning to the iron factory, Shi Yiwen rushed to his office, picked up a pencil and ruler and drew a drawing, and only after about an hour did he call Xu Sicheng and say.

"Now hurry up and build this machine, the woodworking factory is in a hurry to get it, the sooner the better."

The machine is a vertical woodworking band saw machine, the structure of the band saw machine is very simple, it is a sawing machine that uses a ring endless band saw blade as a sawing tool, and makes a one-way continuous linear motion on two cast iron saw wheels to cut wood. It is mainly composed of a bed, a saw wheel, an upper saw wheel lifting and pitching device, a band saw blade tensioning device, a saw blade guide, a workbench, a guide plate, etc. The bed is made of cast iron or steel plate welding, which is a saw machine invented as early as the 1800s, although its saw blade processing is relatively complex, ordinary factories can not process and produce, but the work efficiency is much higher than that of circular sawing machine, the general woodworking band saw machine is used with woodworking sports cars, which is also the reason for its high work efficiency.

Soon, in just two days, a simple hydraulically powered bandsaw was made, the entire machine was made by the ironworks, including the bandsaw blades, which were basically usable, even though the steel used to make the saw blades was rolled from round steel taken from the construction site.

Two days later, with the roar of the bandsaw machine, the carpenters who were still sawing the wood by hand were all surprised to see that the wood that used to take several hours to saw, was sawed effortlessly, and when sawing wood, they even only had to push the stacker.

The sound of the band saw machine sawing wood is extremely harsh, but the efficiency is amazing, so that those carpenters are all dumbfounded, and Carpenter Li, who has done carpenter work all his life, is even more shocked to forget the cigarette pouch, just holding the cigarette pouch and staring at the sawn wood in an instant.

Staring at the log that was two feet long, watching him be easily sawn into a wooden square, it was just a readjustment and fixing four times, a one-foot-long and wide wooden square was sawed out, and then sawed twice in the middle, and it used to take half a day's work, and now it ...... That's half an hour.
