Machine intended to shear, separate the grain from the straw, clean it from other impurities and classify it. The thresher is fed by the farmer standing on the top of it, loading the straw inside the mouth where an appropriate mechanism forces it to enter the machine. Once in the dustpan, the straw it runs on the racks, which acquire a vibratory movement through the crank shaft. The small dirt and the grains arrive through the beater to the board and, from there to the wooden sieve of the screening box. While the dirty grain falls into the sieves, the wind, coming from the fan, throws dust out of the box. A fine sieve lets in the weed seeds, sand, etc., which are ejected laterally, while the pure grain arrives at the elevator, from where it is taken to the defroster. Then go through the second purification. Finally, the product that runs on the different sieves reaches through the channel to the board, being selected in several classes that fall into three bags located at the lower end. I work very hard for the farmer who does it, especially because of the dust and the suspended particles that make the atmosphere breathable.
