9.1 Multi-crop Thresher 9.2 Axial-Flow Paddy Thresher












he thresher consists of frame, threshing cylinder, cylinder casing, concave, oscillating sieves, pulley, belts, four wheels, aspirator blower, winnowing and cleaning attachment. The threshing cylinder is fitted with peg- tooth beaters fitted on the cast iron rings. The main shaft on which threshing cylinder is fixed is supported at two ends by heavy pedal bearings. Various pulleys of different sizes are fitted on this shaft to transmit power to the winnowing and fan attachment. Adjustments for cylinder and blower speeds and concave clearance are provided to make the machine suitable for threshing various crops. For threshing paddy, soybean, maize, sorghum etc., the crop moves axially and is threshed due to impact and rubbing action and the straw is blown away. While threshing wheat, the crop is not allowed to move axially. It is threshed due to impact and rubbing action between cylinder and concave and the straw is broken into small pieces. The grain falling through the concave onto the sieves is cleaned, collected and bagged.

It consists of a threshing cylinder, concave, cylinder casing, cleaning system and feeding chute. In axial flow concept, the crop is fed from one end, moves axially and the straw is thrown out from the other end after complete threshing of the crop. During threshing, the crop rotates three and half times around the cylinder and all the grains get detached. The threshing cylinder is of peg type. The casing of the thresher has 7 louvers for moving the crop axially. Two aspirator blowers and two sieves are provided for cleaning
