<p>Continuous online round grain separator is a machine / device for separating round grains from broken wheat comprises of a mild steel 'L' shaped frame (1) which houses two mild steel rollers (2) at its both ends over which runs a synthetic PUNPCT belt (3) having indented surface to hold on broken wheat grains on its surface carry it u against gravity and discharge them at distant out let at a height (4) but allow round grains to roll down under the gravity to the outlet down opposite to the movement of the belt (5). The synthetic belt (3) is driven by a variable speed DC motor (6) with the help of 'A' type V Belt (7) and pulley ( 8) attached to motor and another pulley (9) attached to the bottom roller (2) driving the belt. Both the rollers (2) are mounted at two ends of the frame supported by four frictionless self-aligning bearings (10). In order to spread and stratify mixture of grains vibration at a particular angle to the belt is transferred through an eccentric loaded pulley (11) also driven by the same motor by two round rubber belts (12). The entire frame is placed and supported on four springs (13) to absorb the vibration created by vibrator (11). The conveyor belt (3) is kept fairly tightened by adjustable bolts (14), provisions to keep the 'V' Belt under tension is by adjusting the base frame of the motor (15) and belt for the eccentric loaded weight also can be kept under tension by the bolt (16), The mixture of round grains and broken wheat is fed at a specific point on top of the synthetic belt by specially designed single line feeding hopper (17). Two rubber guide plates (18) on either side of the belt prevent the jumping off of grains from the belt while machine is in operation</p> |
