Rebirth of the 80s New Farmer

The broken skin conveying roller is an all-metal roller, and the peeling roller is a metal shaft with a rubber gear sleeve.

The working principle is that when the corn with husk enters the peeling part, the husk teeth on the broken husk conveying rod break the husk of the corn, and then the corn cob is clamped and moved by the relatively rotating conveying rod and the peeling rod to remove the husk from the corn cob. To achieve the purpose of peeling, the peeled corn cobs are discharged from the discharge port, and the bracts are discharged from the other port.

The peeling rate is around 90.00%, and the grain damage rate is around [-]%.

The all-metal breaking stick can be processed by the factory, and ordinary lathe workers can complete it.

And rubber sticks are not difficult to find. There is a rubber roller factory in Hongya County, just pick one that meets the specifications.

In the previous life, there were all kinds of skin peeling machines and threshers. Wan Feng played with no less than ten types of skin peeling machines in total. His trouble now is to recall the one with the most reasonable design, the cheapest and the most durable.

After a class and a half of memories, he finally remembered a peeling machine weighing only sixty to seventy catties. He remembered that it was a machine that could feed two ears of corn at the same time. It was very durable and efficient, as if it was a machine at home. Invented by agricultural college students who farmed.

So Wan Feng drew the appearance of the machine on paper according to his memory.

He would also like to draw its internal structure and component views, but this is a bit difficult for him.

It's just that he didn't learn mechanical drawing well in high school. It's no problem for him to draw a view of a simple object, but he's blinded by a more complicated one.

For this, I had to go to Xiao Dexiang, and I just asked him to process a few wheelchair frames.

After the school bell rang, Wan Feng ran out of the classroom with his schoolbag on his back, ignoring Jiang Jun's shouting from behind.

Quickly ran to the carpenter's shop.

Wang He has already finished his wooden box, a total of three fiberboards were made according to Wan Feng's requirements.And gave him a coat of varnish on the outside.

Wan Feng checked it carefully and was very satisfied.

"What are you doing? I weighed it for a long time and didn't figure it out."

You're right if you don't figure it out. If you can figure out what it is, it won't be worth much.

"Are you making this thing strong? It won't break if it falls to the ground, right?"

"Che, you really underestimate my craftsmanship." Wang He picked up a box, took off the back cover and pointed to it, saying, "See, I made the frame inside with thick wooden strips. I told you it was you." The fiberboard is rotten on the outside, but the frame inside is not broken, even a hammer can't break it."

A wooden box more than one foot long, the wooden frame inside this thing is actually half an inch wide, and it is indeed possible that it will not break with a hammer.

Wan Feng is a person who does things because you don't fool me. Of course, I can't let you work for nothing. Three boxes cost $[-].

Not only did they use good materials, but they also painted them with varnish. A pack of glorious cigarettes for thirty cents is nothing.

Not only Wang He was happy, but his father was also happy. It was obvious that the pack of cigarettes would end up in his hands after Wan Feng left.

This is not something that Wan Feng should care about. No matter who owns the smoke, it will be a waste of money for outsiders.

2Chapter 17 Private business's first tape recorder

After going out, Wan Feng got into the broadcasting room again and borrowed Lao Hong's set of electric soldering iron equipment at a price of [-] cents.

Returning to his grandma's house, Wan Feng started his research and creation.

First disassemble the speakers in those broadcast boxes, and after testing proves that they can still work, then use screws to securely fix them two by two side by side in the small box.

He reserved installation positions on both sides of the box.

The small box was divided into three parts by him, with a partition in the middle, so that the place where the speakers were placed on both sides became a small speaker.

It's a pity that there is no professional woofer and can only be replaced by this thing.

He also has a way of making speakers. The pair of speakers he made back then shocked countless people's jaws.

In the previous life, karaoke first appeared in Hongya in the summer of 4000. At that time, a VCD cost more than 1 yuan, and the combined stereo cost more than [-] yuan.

This is not something ordinary people can enjoy.

Around 2000 in 1000, the price of VCD plummeted to about [-] yuan, and the price of non-brand players was around [-] yuan. Only then did they enter the homes of ordinary people.

Karaoke has also become really popular in this small town.

At that time, in summer, there were many people singing karaoke on both sides of the avenue from Yongshi Commune to Hongya County.

A TV set, a sound system and a VCD can be opened on the side of the road.

Anyone can sing a song for two yuan.

Wan Feng, who loves to sing, often goes to sing and spends a lot of money.

Later, I thought it would be better to spend this unjustified money than to get a set to sing how I like at home. Anyway, I have a VCD, so I just need to buy a power amplifier and a pair of speakers.

Action is not as good as heartbeat, so he spent 800 yuan to buy a pair of speakers and a power amplifier.

Come back and pick up a song, the voice is horrible.

The 800 yuan audio combination is simply a commodity thrown on the street. How can the sound be so good?

This is not a problem, Wan Feng can change it himself.

Buy an enlarged version, buy components, and change a transformer. A broken power amplifier that costs more than 400 yuan is turned into a product that is no less than a thousand yuan.

He sold the speakers to a villager in the same village for a price of [-] yuan. He bought a pair of woofers with a diameter of [-] centimeters and a pair of tweeters, and then made a pair with the combined version. Speakers in stage shape.

The sound effect is OK, but there is noise, and when the bass is heavy, the speaker will make a sound of Ula Ula.

The paralyzed Lao Tzu is not what the Soviets want Ulla to do!

The reason was found. The board used to make the speaker is too thin, and it will vibrate and generate noise when it is subjected to the flow of sound waves.

Speakers should be made of composite boards with a thickness of at least one centimeter. He didn't know much about it when he first encountered it, so he bought a board that was only three or four millimeters thick.

This problem is not easy to solve.

It can't be dismantled and redone.

Wan Feng wandered around the street trying to figure out how to solve this problem, but it happened that the highway team on the street was repairing the road and filtering the asphalt.

Wan Feng slapped his head: Yes.

He ran to get some unmelted asphalt and went home.

What are you doing?Isn't the speaker board thin, isn't there vibration and noise!I pour asphalt into the box to see if you still vibrate!

In order to prevent the filled asphalt from falling off due to vibration over time, he nailed some nails on the box, pulled some iron wires on the nails, and finally melted the asphalt and mixed some rosin and other substances that can increase the stickiness. The bottom and corners are all filled.

what's the result?

There is no more noise, and the tone is awesome.
