Abstract
PURPOSE: To miniaturize a tubular pump used for transfer of concrete, by forming a hollow housing to the arm base part for orbital motion of a squeeze roller and arranging built-in speed change and reduction gears.
CONSTITUTION: A housing 3 is formed in the base part of a squeeze roller 4 making orbital motion in the inside of a pumping tube 2, and an operating shaft 15, provided with four peripherally cut grooves 15a, is fitted to the center hole of an input shaft 10 externally fitted with a sliding gear 13 and the first intermediate gear train 14. There is further provided in the housing 3 the second intermediate gear train 22 meshed respectively to a reduction gear input shaft gear 24, having a sun gear 24a meshed to a planetary gear 26 giving speed reduction rotary motion, and the first intermediate gear train 14. During rotating motion of the input shaft 10, the position of the peripheral 15a engaged to a stopper ball 20 is changed to shift a gear, meshed to the sliding gear 13, to the reduction gear input shaft gear 24, the second intermediate gear train 22 and the first intermediate gear train 23 respectively, thus each of the rotations at high, low and medium speed is transmitted to the sun gear 24a.
