SPRAY EQUIPMENT FOR MORTAR

摘要

A Y type suction pipe (27) connected to the lower of a mortar hopper (6), piston heads (43a),(43b) and piston rods (42a)(42b) reciprocating in cylinders (23a)(23b), a cranks (21a)(21b) connected to a crank shaft (21) at which a coupled gear (22) linked to a driving gear (20) of the shaft (19') of a reduction pulley (19) is provided constitute a spray device (7). The cylinders (23a)(23b) are alternatively operated so that the cement mortar supplied and storaged at the hopper can be sprayed through a pipe (30).
