摘要： PURPOSE:To scrape a large quantity of snow at a high speed under any landform and accumulated snow condition by installing first and second shafts in parallel which are provided with a snow scraping auger and a snow feeding screw and operate in conjunction with each other. CONSTITUTION:A first shaft 2 is rotted by a motor 7 to rotate a snow scraping auger 1, which scrapes snow into a housing 3. A second shaft 6 which operates in conjunction with the shaft 2 is rotated to suction snow which is scraped to the center of the housing 3 from a snow suction port 42 into a snow transportation pipe 4. Snow is extruded by a snow feeding screw 5 of the shaft 6 to gain an initial speed, and then it is transferred on air current. An opening and closing valve may be mounted near a connecting end 41, or at least one suction port may be mounted in the blocked suction at the other end of the pipe 4 to ensure suction air current. Preferably, a hold section is mounted on the housing 3.

摘要： PURPOSE:To fill a powdery/granular material in a packaging bag by the same speed with a powdery/granular material feeding device for which compressed air is used by sending out a powdery/granular material from a feeding port by a screw conveyor for powdery/granular material feeding. CONSTITUTION:A powdery/granular material which has been thrown in a hopper drops at the rear end part of a screw conveyor for feeding 12 while being agitated by a agitator 14. Then, the powdery/granular material is carried in the horizontal direction by the screw conveyor for feeding 12, and by the front tip part, is fed around the rear end of a screw conveyor for feeding 10. The powdery/granular material which has been fed around the rear end of the screw conveyor for feeding 10 is press-fed in the horizontal direction toward a feeding port 62 by the screw conveyor for feeding 10. The powdery/granular material which has been press-fed to the front tip part of the screw conveyor for feeding 10 is press-fed to the feeding port 62 by a screw conveyor for feeding 64, and is sent out to a filling pipe 74 from the feeding port 62. By this method, a filling of powdery/granular material can be performed by a high filling speed which is equivalent to the powdery/granular material feeding device.

摘要： PURPOSE:To accomplish stable plug formation by setting the section of the feed pressure pipe of a copper pipe or an austenite stainless steel pipe to be at least specified times as long as a feed pressure pipe diameter from an ejector section. CONSTITUTION:The delivery pipe 6 of a section with the length of a delivery pipe 6 at least 100-200 times as long as its diameter from the section of an ejector 5 is made to be a copper pipe or an austenite stainless steel pipe. Then, the delivery object of sludge or the like stored in a feed mud hopper 1 is energized from the jet port 2a of a screw conveyor 2 by a pressure applying device 3, and is directed to the ejector 5. Besides, compressed air fed from a compressor 4a is blown into the delivery pipe 6 from an air blowing pipe 5b via a compressed air feeding pipe 4b and a solenoid switch valve 5a, and the delivery object is delivered into the delivery pipe 6 in the state of plug flow.

摘要： PURPOSE:To accomplish a stable plug formation by lining the internal surface of a feed pressure pipe with the lining material of less sliding resistance, and by setting its section from an ejector section at least specified times as long as a feed pressure pipe diameter. CONSTITUTION:The internal surface of the delivery pipe 6 of a section with the length at least 100-200 times as long as a delivery pipe diameter from the section of an ejector 5 is lined with the lining material of the less sliding resis tance of polyurethane or the like for example. Then, a delivery object stored in a feed mud hopper 1 is energized from the jet port 2a of a screw conveyor 2 by a pressure applying device 3, and is directed to the ejector 5. Besides, compressed air fed from a compressor 4a is blown into the delivery pipe 6 form an air blowing pipe 5b via a compressed air feeding pipe 4b and an electro magnetic switch valve 5a, and the delivery object is delivered into the delivery pipe 6 in the state of plug flow.

摘要： PURPOSE:To reduce a loss of energy as small as possible by constituting a device by drop charging powder or the like from a material silo to be fed transferring by a screw feed transfer unit approaching a transport pipe and transporting in this pipe the powder by pressure air. CONSTITUTION:A motor 24 rotates a screw transfer feed unit 15 while drives an air blower 26, when a damper 34 is opened of a material silo 30, its internal powder or the like drops from a dropping port 31 through a charge port 14 into a cylinder 11 charged in its side with the powder. As the result, this powder or the like is fed transferring by a screw blade 18 and supplied to a side of feed port 13. While pressure air, supplied from the air blower 26 to a base end of a pipe shaft 16, is jetted passing through its inside to the feed port 13 from a nozzle 17. In case of the powder or the like being transported passing through this transport pipe 32, the pressure of jetted air acts on all the powder or the like fed efficiently to the pipe 32 because the cylinder 11 is narrowed, formed in its point end side into a tapered shape and placed in a condition enabling the powder or the like to be always collected in a tapered chamber.

摘要： PURPOSE:To enable the continuous supply and efficient pipeline conveyance of transfer material by providing a transfer material supply means at the upstream end part of a conveyance pipe and Coanda pumps on the downstream side thereof, so that the transfer material can be conveyed by the flow formed inside the pipe. CONSTITUTION:Granules 12 are supplied from a transfer material supply means 13 provided at the upper end part 11A of a conveyance pipe 11, and further compressed air is supplied to Coanda pumps 20 through a compressed air supply means 21, so that flow is generated inside the conveyance pipe 11 by the Coanda pumps 20. And the velocity of flow formed inside the conveyance pipe 11 at the outer circumferential part is greater than that at the inside of flow, and further the flow rate is increased compared with the flow rate of jet from injection nozzles. Thus, the granules 12 at the upstream end part 11A are taken into flow by a suction Coanda pump 20A and further the flow is maintained along the overall length of the conveyance pipe 11 by accelerating Coanda pumps 20B which are arranged at specified intervals along the conveyance pipe 11, so that the granules 12 can be conveyed with the flow to the downstream end part 11B.
