Amendment September 9, 1983 The scope of claims for utility model registration is amended as follows.

[Scope of Claim for Utility Model Registration] (1) The jet head 24 opens toward the left and right and upward of the frame 16 , and is provided with a plurality of nozzles 36 at appropriate intervals along the periphery, so that the chemical liquid from the nozzles 36 is In the speed sprayer 10, which is conveyed to the surroundings by the wind from the blower 26 to the jet head 24, the sprayer is arranged at appropriate intervals along the upper side of the jet head 24, and is moved in the direction of the side of the jet head 24 by supplying pressure medium inside. a plurality of hollow elastic members 38 that are expandable and contractible;
72, and a valve device 60 for controlling the amount of pressure medium supplied to the hollow elastic members 38, 72. (2) The speed sprayer according to claim 1, wherein the hollow elastic members 38, 72 have a rectifying cross section in the wind flow direction. (3) The hollow elastic members 38, 72 have an airfoil-shaped cross section in the wind flow direction, and the linear introduction pipe 52 connects the hollow space 40 of the hollow elastic members 38, 72 with the airfoil-shaped cross section. 3. The pressure medium according to claim 2, which extends in the longitudinal direction and along the upstream end, is fixed to the inner surface of the upstream short portion of the linear introduction pipe 52, and guides the pressure medium into the hollow space 40. speed sprayer. (4) The hollow elastic members 38 and 72 are characterized in that the cross section in the wind flow direction is triangular in shape, with the maximum width portion and the apex opposite to the maximum width portion facing upstream and downstream, respectively. A speed sprayer according to claim 1. (5) The speed sprayer according to any one of claims 1 to 4 , wherein the pressure medium is a gas supplied from an air compressor 64. (6) The pressure medium is a chemical liquid discharged from a power sprayer 68 mounted on the speed sprayer 10.
The speed sprayer described in 4 .
