<p>PURPOSE:To perform continuous conveyance of high power efficiency by coupling with each other, the first cylinder provided with an suction valve on its piston, and the second cylinder provided with a discharge valve on its piston by means of a junction box at the rear ends of both cylinders in order to build up a pressure- forcing conveying device of pulverized grain. CONSTITUTION:The first and the second cylinders 2, 2' are arranged in parallel to each other with their rear ends coupled by means of means of a junction box. Pistons 11, 11', which make reciprocating motion by means of a single crank arm 23 are equiped with intake ports 15, 15' and elastic valves 26, 26' which open and close in the opposite direction to each other. By moving to the left, the first piston 2 absorbs pulverized grain while the second piston 2' conveys the same by pressure. By moving to the right, the first piston 2 presses the pulverized grain into the junction box 4 while the second piston 2' discharges the same. For further smooth flow of pulverized grain, high-pressure air 47 is jetted from appropriate points in accordance with the progress of work.</p> |
