There are six classes with nearly 60 students in each class, and there is even a 6th grade class.

As far as Wan Feng knew, there were three brigades of primary schools in the entire commune that kept the sixth grade class, and for no other reason, the middle school did not have so many classrooms to accommodate, so it had to be dispersed to the brigades.

This is a phenomenon that people cannot understand thirty years later.

But who would have thought that thirty years later, Jiangwei School, which was once full of people, would be merged with Pingshan Brigade School because there were not many students, and even if it was merged, there would only be about thirty people in a class. And this situation is not limited to Jiangwei, but is widespread throughout the country.

It seems that overnight, the problem of depopulation has abruptly appeared.

However, this is not a problem that Wan Feng is worried about, what he is worried about now is whether Chen Wenxin can embroider the trademark for him and the problem of picking bud rice.

The requirements for trademarks are not too high, and Wan Feng's requirements are as long as the pattern has seven or eight points of image.

That's just a sign.

Chen Wenxin swore that she would definitely be able to do a good job.

Then there is only one question left for Wan Feng to worry about.

Today is the first day of September, and there is still about a month before the mountain is closed, so Wan Feng should be in time to calculate it.

When I went to school in the afternoon, Wan Feng didn't listen to what the teacher said, but just wrote and drew on the desk.

He recalls designing a small corn peeler.

He can't make a large one even if he recalls, one is the industrial level at that time, and the other is of course the problem of money, Zhang Hai will definitely not give him too much money.

Then it's better to get a light and small one without bothering, and the price of this small machine can't exceed 100 yuan.

This thing Wan Feng is no stranger to at all, in his last life, he fiddled with a lot of agricultural machinery, all kinds of things.

Especially after 10 years, every household in the countryside has a few machines that use electricity to burn oil, and almost most people will ask him to repair any failure of these machines within a radius of 20 miles.

The reason is that he repairs it well and charges a low fee.

Therefore, it is not difficult to get him to get a corn peeler out, as long as the environment allows.

On the corn side alone, there are peelers and threshers, as well as integrated peeling and threshers.

The integrated peeling and threshing machine is not actually very practical, and in some areas, peeling and threshing are carried out separately.

For example, the corn with high humidity is peeled and threshed as soon as it is brought back from the field, where do you go to get such a large drying site? Do you dare to enter the warehouse and bag it if it is not dried?

Another reason is that the peeling thresher is prone to failure and troublesome maintenance.

Therefore, Wan Feng did not plan to combine them together, peeling to peeling, threshing to threshing.

Anyway, Zhang Hai was only worried about peeling and not worrying about threshing.

There is nothing too high-tech about the corn peeling machine, a motor, a frame, a set of peeling mechanism, a thing called a pressure feeder plus some springs are almost all its belongings.

Among these components, the electric motor is the most valuable thing, although it is only a small power motor, it costs at least thirty to forty yuan.

It takes up almost half of Wanfeng's budget.

Electric motors and frames are easy to do, and the cities in the Northeast have a little advantage regardless of their size, that is, almost every city has a lot of factories that can produce a lot of industrial products, and the name of the country's first industrial base is not called in vain.

Products such as electric motors, which were considered high-end at the time, were produced by the Hongya County Motor Factory, and even the Machinery Factory of the Warrior Commune also produced some low-power motors.

Since this machine is called a peeling machine, of course, the key place is the peeling mechanism.

The main components of the peeling mechanism are two rollers, which are called the broken skin conveyor stick and the rubber peeling stick, and the broken skin conveyor stick has broken shell teeth.

The skin-breaking conveyor stick is an all-metal roller, and the skinning stick is a rubber tooth sleeve with a metal shaft jacket.

The working principle is that when the corn with the skin enters the peeling part, the shell-breaking teeth on the skin-breaking conveyor stick scratch the bract of the corn, and then the corn cob is clamped and moved by the relatively rotating conveying stick and the peeling stick to tear the bract off from the corn cob, so as to achieve the purpose of peeling, and then the corn cob of the peeling is discharged from the discharge port, and the bract is discharged from the other mouth.

The peeling rate is about 90 percent, and the grain breakage rate is about 1 percent.

The all-metal leather breaking stick can be processed by the factory, and the average lathe can be completed.

And rubber sticks are not difficult to find, there is a rubber roller factory in Hongya County, and you can pick one that meets the specifications.

In the previous life, there were all kinds of peeling machine threshers, and Wan Feng fiddled with no less than ten styles of peeling machines, and now his trouble is to recall the most reasonable design, the cheapest and most durable one.

After a half class of reminiscences, he finally remembered a peeling machine weighing only sixty or seventy pounds, remembering that this was a machine that could feed two ears of corn at the same time, which was very durable and efficient, as if it was invented by an agricultural college student who was farming at home at that time.

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

He also wanted to draw a view of its internals and parts, but that was a bit of a problem for him.

It's just that I didn't learn mechanical drawing well in high school, so it's okay to let him draw a view of a simple object, but if it's a little more complicated, he'll be blind.

I have to go to Xiao Dexiang for this, just let him process a few pairs of wheelchair racks.

After the bell rang for the end of school, Wan Feng ran out of the classroom with his schoolbag on his back, and he didn't even pay attention to Jiang Jun shouting in the back.

A puff of smoke ran to the carpenter's shop.

Wang He had already made his wooden box, and a total of three fiberboards were made in accordance with Wan Feng's requirements. And also painted him on the outside.

Wan Feng carefully checked it and was very satisfied.

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

If you don't figure it out, it's worthless if you can figure out what it is.

"Aren't you making this thing sturdy, can't you break it if you fall into the ground?"

"Cut, you really underestimate my craft. Wang He picked up a box, took off the back cover, pointed inside, and said: "See, I made the frame inside with thick wooden strips, and tell you that the fiberboard on the outside of you is rotten, and the frame inside is not broken, and it can't be broken with a hammer." ”

A wooden box more than a foot long, the wooden strip used to make the frame in this goods is half an inch wide, and it is indeed possible that it will not be broken with a hammer.

Wan Feng, this person is that you don't fool me, of course I can't let you work in vain, three boxes are five for a piece, not only gave five cents more, but also slapped the pack of glorious cigarettes that only smoked two.

People not only used good materials but also painted them with lacquer, and a pack of glorious cigarettes is nothing.

Not only Wang He was happy, but also his Lao Tzu, it was obvious that after Wan Feng left, the pack of cigarettes would be in his hands.

This is not something that Wan Feng should be in charge of, no matter who the cigarette is in his hands, it is also a fertilizer and water that has fallen into the fields of outsiders.
