摘要： PURPOSE:To efficiently and continuously agitatingly mix hydraulic material with accelerator and discharge the resultant mixture by a structure wherein a screw is inserted rotatably at high speed in a tubular casing, at the tip side of which a discharge port is provided, and, at the same time, a hydraulic material charging part and an accelerator adding part are provided. CONSTITUTION:A discharge port 10 is provided at the front end of a tubular casing 1, which is made of flexible material or the inner surface of which is lined by flexible material. The rear part of a screw shaft 2a is cantileveredly supported by a bearing block 20, to which a high speed driving motor 3 and a reduction unit 30 are provided. The screw shaft 2a has continuous blades 2b and 2b and agitating blades 2c. The ratio of the total number of continuous blades to the number of pitch of the agitating blades is essentially set to be (2.5 - 3.5):1 for realizing favorable agitating and feeding effect without the solidification of accelerator. A hydraulic material charging part 5 is open on the tubular casing 1 in the continuous blade 2b range at the base end. The rear end side of the part is directly connected to a pressure feed piping 50 and lead to a pressure feed pump 6. An accelerator adding part 7 is provided at an arbitrary position on the hydraulic material charging part 5 and lead through a supply hose 70 to an accelerator feeding device 8. The favorable accelerator feeding device 8 is of dense flow pressure feed type.

摘要： PURPOSE:To enable sure simple execution by providing on the front end of a machine body an impeller connected to a mixture supply means and on the peripheral side of the impeller a rotary shaft to change the direction of projection with a pivotal operation mechanism or project the mixture parallel to the execution plane. CONSTITUTION:A collapsible arm 52 is mounted to a machine body 50 having a travelling means 51. and provided on the front end with a slide lever 53 and a projecting mechanism 10. Then, the projecting mechanism 10 is provided with a rotary impeller l and mixture supply means 2 and a connecting member 3 for these means is provided with a rotary shaft 4 connected to a motor 33. Next, the supply means 2 is provided with a ribbon screw 21 rotated by a motor 22 to send the mixture sent from a supply port 26 to the peripheral side of the impeller l and mix it by a change-over piece 24. A quick-setting agent or the like is replenished from an introducing port 27 to form an introducing section 25 having rubber-like elasticity. Thus, the rate of rebound and a produced powder dust amount are reduced so that the mixture projection excellent in strength can be performed.
