Li Chao plans to build a threshing machine.

Before harvesters were popularized in the countryside, many farmers in the mountains actually used a threshing machine to harvest rice with their feet.

Later, the diesel engine was used to replace the pedal, and later it became a harvester.

In fact, that kind of pedaling machine is quite simple.

It is two sets of gears that rotate through pedaling and rotating, and the gears rotate, driving a roller in the middle.

The roller is equipped with n-shaped iron made of iron and is installed on the roller rows.

In this way, when the foot presses the pedal, the gears take the drum, and then puts the rice in, it can be threshed, which is fast and convenient.

Compared to hitting with one hand, it is more than ten times faster.

The key to this kind of grinding machine is the gear set, then the roller, and a wooden silo, and a wooden shed that can be disassembled and combined is made above the roller, even if the great work is completed.

Once you kick, you will whimper, but the efficiency is absolutely good.

That set of gears is not difficult, but in this era, all iron tools are very expensive. What's more, this set of gears is considered a more sophisticated one.

Li Chao was also considering using harder wood to make a set of gear bearings, which is like parts on a carriage. Don’t you also use wood?

However, Li Chao still planned to build a set of iron first and then some wood.

But before delivering it to the blacksmith for production, Li Chao had to produce the design drawings first.

The design drawings have been drawn. Now he is going to make a small wooden model by himself and make a relatively standard model, one to one proportion. Then, he will use it for the craftsmen to create various parts in comparison, which will be more concise and clear.

The name of this machine Li Chao was directly named as the foot-pedal grinding machine.
