摘要： PURPOSE:To effect correct airflow amount measurement within comparatively short period of time by a method wherein a hopper, capable of covering a blow-off port for air conditioning, a duct, connected and communicated with the hopper, and an anemometer, arranged in the duct, are provided in the device. CONSTITUTION:A funnel-shaped hopper 9 is formed with the size of a degree capable of covering the whole of the blow-off port 11 for air conditioning as it is including an anemostat 10 or the like and the straight duct 12 for measuring the airflow speed, which is provided with a proper length, is connected to and communicated with the duct 12. Various kinds of anemometer 13 and thermometer 14 of thermal wire type or the like are arranged at the downstream side of a position whereat the air, flowed thereinto through the hopper 9, becomes laminar flow, so as to be free of changing or fixing the position thereof into the radial direction of the duct 12. The duct 12 is fixed to a holding frame 15 in a condition that the hopper 9 is located toward the upper side thereof while left and right engaging members 16a, 16b, provided in this holding frame 15, are engaged with and held by legs 8a, 8b. According to this method, there is no trouble to measure the airflow speed by deviating the anemometer sequentially into the radial direction of the duct and the average flow speed may be read immediately.

摘要： PURPOSE:To reduce the man-hour for transportation at the time of dust collecting by using duct for artificial turf flotation equipment for mounting a dust chute and a collecting device. CONSTITUTION:This stadium is provided with a winding device 5 which lays artificial turf 2 on a ground base 1 and winds up the artificial turf to remove it, and flotation equipment 6 for blowing artificial turf flotation air to the lower surface of the artificial turf 2 from plural discharge ports 6A which are dispersedly-disposed at the ground base 1. Moreover, a dust chute 7 which can open and close for throwing dust is provided with an air feed duct 6C which feeds blowing air to a blower port 6A, and a dust collecting device 8 which collects dust in the duct C which is sucked from the duct C.
