WHEAT THRESHER MACHINE SPECIFICATIONS:
This machine can give up to 40 maunds wheat per hour. A tractor or electric motor of 30 to 40 horsepower is needed to run it. Besides wheat, this thresher machine is also useful for Gram, Pulses and Mustard.
Modern day combine harvesters (or simply combines) operate on the same principles and use the same components as the original threshing machines built in the 19th century. Combines also perform the reaping operation at the same time. The name combine is derived from the fact that the two steps are combined in a single machine. Also, most modern combines are self-powered (usually by a diesel engine) and self-propelled, although tractor powered, pull type combines models were offered by John Deere and Case International into the 1990s.
Today, as in the 19th century, the threshing begins with a cylinder and concave. The cylinder has sharp serrated bars, and rotates at high speed (about 500 RPM), so that the bars beat against the entire plant as it is mechanically fed from the reaping equipment at the front of the combine to the gap between the concave and the rotating beater/cylinder. The concave is curved to match the curve of the cylinder, and the grain, now separated from the plant stalks falls immediately through grated openings in the concave as it is beaten. The motion of the rotating cylinder thrusts the remaining straw and chaff toward the rear of the machine.
Every farmer cannot buy combine harvester as it is out of their buying power. This machine is much economical for threshing of wheat crop for a middle farmer. Although combine harvester cuts the crop and threshes it in the same time. But its cost is much high, alternative for this machine is tractor operated thresher machine. Price and specification of wheat thrasher machines are given below.
