Cosechadoras combinadas

The video explains the challenges of harvesting cereal crops and introduces combine harvesters as a solution. It details the mechanical process of separating grain from the plant, including cutting, crushing, and filtering. The leftover chaff is removed, and the grains are collected in a tank. The name 'combine' comes from the machine's ability to combine multiple harvesting tasks.

What is one of the main challenges in harvesting cereal crops?

• The fields are often very large.

• The crops are too small to see.

• The crops are too heavy to lift.

• The crops grow too quickly.

What is the primary function of a combine harvester?

• To water the crops.

• To transport crops to the market.

• To plant seeds in the field.

• To mechanically separate grain from the plant.

What happens to the outer shells of the plants during the harvesting process?

• They are used as fertilizer.

• They are left in the field.

• They are collected with the grains.

• They are removed and known as chaff.

How does the combine harvester ensure only grains are collected?

• By using a magnet.

• By using a strainer with a specific grid size.

• By using a vacuum.

• By using a color sensor.

Where are the grains collected after being separated by the combine?

• In a basket.

• In a storage barn.

• In a collection tank.

• In a silo.
