PROBLEM TO BE SOLVED: To provide the easy attachment and detachment and high sealability of the discharge cylinder (chute) disposed in the machine body of a particulate material quantitative feeder or a particulate material mixing or stirring machine. SOLUTION: A discharge port 3 is formed in the end plate or bottom plate 2 of the machine body 1 of a particulate material supplying, mixing or stirring machine and opposed guide grooves 4, 4' are formed in both outsides of the discharge port 3 and the interval W between the groove bottoms 4" of both grooves 4, 4' is larger than the insertion width (w) of the groove insertion flange 6, 6' disposed at one end of the discharge cylinder 5 and the interval (w') between groove inlets is smaller than the insertion width (w) and the opposed surfaces 7, 7' of one guide groove 4 and the flange 6 inserted into the groove 4 are formed as taper surfaces inclined so as to become narrow in groove width toward groove bottoms 4" and the groove width (t) of the other guide groove 4 is made larger than the thickness of the flange 6' inserted into the guide grooves 4' and the clamping jig 9 clamping the projecting plate 8 disposed in the midway part of the discharge cylinder 5 toward the above-mentioned end plate or bottom plate is disposed in the outer surface of the other guide groove 4'.
