接続する。The features of the present invention are as follows. Under the hopper 1 and in front of the hopper 1
The cylinder 7 whose rear end is closed is provided, and the screw shaft 12 is extended from the end of the screw 11 ′ of the screw conveyor 11 provided in the cylinder 7 to form an extension 12 ′.
Spray cylinder 14 connected to compressor and spray hose 2
1 is connected to a discharge cylinder 18 having an inner diameter larger than the inner diameter of the injection cylinder 14 by screwing near the shaft end of the extension 12 '.
An opening is formed in the cylinder 7 so as to be orthogonal to and opposite to the conveying direction of the conveyor 11, and the two cylinders 14 and 18 are connected by a connecting hose 20.
