What are the irrigation tools for farmland?

1, rollover rollover, also known as dragon bone vehicle, is an irrigation machine that uses sprocket drive to drive the scraper in the sink to overturn, thus guiding the water from the lower part to the higher part. Dumpers appeared in the Eastern Han Dynasty. After the Three Kingdoms, Ma Jun's improvement became a tool to irrigate gardens, and it was not until the Tang Dynasty that agricultural irrigation machinery flourished.

2. The pipe truck was invented in Sui Dynasty, which is an agricultural irrigation machine that uses water to impact the rotation of the waterwheel. Generally, trucks should be installed on rivers with running water and dig a geosyncline. The rapids introduced into the geosyncline push the waterwheel to rotate continuously.

In this way, the water in the geosyncline is lifted to a high place through the wooden pipe or bamboo pipe on the water carriage, and finally flows into the farmland for irrigation. The automatic operation of trucks is realized by the impact of rapids, so the use of trucks is limited by certain terrain.

3. Well truck: Well truck is an ancient tool developed from winch, which is used to pump water from deep wells for irrigation. The rope is wound on the log, which is horizontal, and the log rotates to drive the rope. The bucket rises and falls to get water, and the bucket only rises and falls in a straight line. Can't rotate around the log.

Structure and principle: many wooden barrels are connected in a string with a small horizontal shaft, like a big chain, which is sleeved on the big wheel on the well; At one end of the shaft of this big wheel, a big vertical gear is installed, and then it is connected with a big horizontal gear at the upper part.
