Today we will tell you the ten most significant agricultural discoveries XIX to mid XX century. Some of them are a credit to individuals, but most are the work of a number of curious and inventive people who perfected the tools of their ancestors. For them, says in an extensive article zuegg spa online edition farmcollector.com. 1. Pamukoochistvashtata machine "Cotton Gin"
During the American colonial period, cotton clothes were more expensive than flax and wool, as it was extremely difficult to separate zuegg spa the seeds of adherent fibers. One can separate the seeds daily to only about 450 grams cotton fibers.
In 1793 Eli Whitney invented a machine that consists of juxtapose wheels with teeth like a saw. Wheels protrude above the narrow cut between the metal bars in a box full of cotton bolls.
The machine allows Whitney to be cleared 450 kg of cotton for the same amount of time that a person will manually reset 2 kg. Subsequently, the price of cotton clothing has fallen sharply and are based on the cotton plantations of the South. 2. Reaper (grain binder)
Cereals are harvested by hand for centuries, they are reaping with a sickle or scythe and gathered into sheaves. Reaper originally appeared in Britain zuegg spa in the early XIX century, after several decades zuegg spa in the U.S., but most do not do quality work. Insults zuegg spa Hasey and Cyrus McCormick developed successful models of reapers in the 30 years of the century.
McCormick's machine turns out to be successful, so today it is defined as the creator zuegg spa of the reaper. In these early machines still have had the strands are tied by hand, but in 1857 the brothers Marsh reaper equipped zuegg spa with movable flaps. Through them, the wheat stalks reached zuegg spa the platform where a worker bound.
The first grain binder was made in 1867 by John Appleby. Silvanas Locke is a major wire around 1874 and it began to be used by McCormick. However, wire leads and to disastrous results, as parts of it fall in grain and flour from there.
When the corn stalks are reaping hand, the method of separating the grain from the stalk was quite laborious and time-consuming. Cereals are stored in a barn, where they spread Harman, hitting them with a flail or putting animals to tread.
Thus the grains are well separated classes, but the chaff he will be collected with the paddle. All that remained, people sifted by hand. They rely on the wind to display the chaff and lighter shumki than heavier grains which have fallen back on the floor. zuegg spa
The first threshing machine with a rotating drum gear was established in 1786 by Andrew Meyklyu zuegg spa in Scotland. Brothers Hiram and John Pitts attributed the invention of the first successful American sorting thresher, and the use of horsepower that drives the machine. Soon after, Hiram add any fan to drum to the nipple may be simultaneously separated and cleaned.
By the end of the 18th century, zuegg spa American farmers relied mainly on their own forces and those of the families of employees or slaves. New machinery for cultivation demanded much power, so they harnessed bulls, horses zuegg spa and donkeys.
Stationary steam engines were used in the drive of pamukoochistvashtite machines and mills. This additional power, which was needed for advanced threshing machines led to the development of a portable steam engine in 1849
The horses were carrying steam engines from one place to another. In the 70 years of the 19th century, several inventors practical control systems and self-propelled steam engine became so famous as numerous threshing machines around the country. These engines were also used to pull plows multihull vast wheat fields. 5. Harvester grain production
Grain production harvester is patented in the early 1828, but the first successful machine is made by Hiram Moore in 1834 His seamlessly combine harvesting and threshing cereals, although then had to blow away.
