Multi Crop Thresher
Madanlal Kumawat
Jaipur, Rajasthan

1st National Grassroots Innovation - 2001

 Catalog

Farmers across India require a reliable machine that achieves threshing with minimal grain breakage and clean output for a variety of crops. Madanlal Kumawat, farm equipment manufacturer observed about the problems of conventional threshers like breaking of grains, impurities in the threshed grains, inconvenience of changing different threshes and several other operational and mechanical problems. Moreover there was no thresher available which can thresh all kind of crops as in the market the threshers available can thresh one or maximum two crops.
 
The innovator has developed a versatile thresher that can meet these needs. It is a high capacity thresher, which can handle multiple crops (cereals, pulses etc.) including groundnuts with minimum machine adjustments. Threshed grains are cleaner and do not need further cleaning before bagging up, which saves time and energy. The switch over time for setting it up for different crops is less than 15 minutes. It contains an initial cutter that cuts the straws into pieces thereby reducing the power consumption required for threshing.
Mr. Madan Lal Kumavat lives in Jaipur district in a village known as Balmukundpura, which is near Bagru village. He and his brother have studied upto primary level. His brother Shankar Lalji has been working in a small company which makes threshers. He learned all the things required for making threshers, and he has taken care that the problems faced by the farmers should not repeat in his machine.

Improved Thresher:

He has devised a thresher, by changing the sieves of which, grain seeds, oil seeds and pulse crops could be threshed. It has only two bearings, which could be changed easily.

Advantages:

The quality of the seeds threshed with the help of this thresher is good and hence they could be packed directly. It has a capacity to thresh 15-30 quintals of seeds / hour. 

In year 2010, he was chosen by Forbes Magazine as one of the seven most powerful innovators of Rural India. He has also been awarded by the State Government for the same innovation in November 2004. He was recognized by National Innovation Foundation in t

Indian Patent Granted (No. 253863 )

The thresher is divided into three main sections a) The feed in unit b) The cutting & threshing unit and c) The grain separation chamber. The feed mechanism has a gearbox, which is used to rotate five cylinder of the feed mechanism with different speeds to enable effective feeding to different crops requiring different rate of feed.
