项目摘要

A snow shooter blowing snow into the tubes of which snow is transported with high-speed air flow has been made. The shooter is consisted of a cylindrical casing, rotating plates and a auger, to minimize decreasing of the speed of the air flow. The plates are to send snow into the tube, and the auger is to grind snow blocks into uniformaly smaller size to avoid stacks of snow blocks in the tube. The shooter was tested out of doors, and the characteristics were almost as expected.Snow blocks in the tubes were video-taped, and both the velocity and the locus of these blocks were analyzed. The velocity at the bending tube decreased temporarily, and this decreasing would make the stacks be easy to happen. The bending tube in short length seemed to have a radius of curvature minimizing the decreasing. Also behaviors of snow blocks at junctions were analyzed.An air-blower is the best for main power unit to make high-speed air flow in the tube, and high-pressured air generator like an air compressor best for booster. For extending the length of snow transport, adding the boosters is better than increasing the power of an air-blower.The formation of the tube, an air-blower and a compressor/s and the shooter/s is a basic unit for snow transport with high-speed air flow. By joining the basic units with each others, a snow removal machine, which can manage snow on streets or roofs in the area crowded with houses, will be for practical use.

一名雪射手将雪吹入管子的管子中，雪已经用高速气流运输了。射击器由圆柱套管，旋转板和螺旋钻组成，以最大程度地减少气流速度的降低。盘子要将雪送入管子，螺旋钻是要将雪地块磨成均匀的尺寸较小，以避免管子中的积雪块。射击者是在门外测试的，并且特征几乎符合预期。试管中的snow块是视频框的，并且分析了这些块的速度和基因座。弯管的速度暂时下降，这种下降将使堆栈易于实现。弯曲管的短长度似乎具有最小化减小的曲率半径。还分析了在交界处的雪块的行为。气吹架者是主动力单元在管中进行高速空气流的最佳选择，而高压空气发生器（如空气压缩机）最适合增压器。为了延长降雪的长度，添加助推器比增加气动器的力量更好。管的形成，气动器和压缩机和射击器和射手S是具有高速空气流量的雪运输的基本单位。通过彼此加入基本单元，可以实际使用的降雪机，该机器可以在拥挤的房屋的街道或屋顶上管理雪。
