摘要： A method for bagging leaves includes assembling a leaf bagger comprising a gathering bin having an inlet that tapers down to an outlet. A first end of a tunnel is coupled to the outlet. The method couples, to a second end of the tunnel, an oversize garbage bag. The oversize garbage bag has a volume of at least 60 gallons. The method further moistens leaves to be gathered by the leaf bagger and blows the moistened leaves into the inlet of the leaf bagger for accumulation in the oversize garbage bag. A corresponding apparatus is also described and claimed herein.

摘要： Provided is an axial flow blower capable of improving an intake efficiency even when air is introduced from a plurality of suction openings. An axial flow blower includes a housing including an air blowing passage extending from a plurality of suction openings (lateral suction opening and lower suction opening) to an ejection opening, an electric motor, and an air blowing fan that blows air from the plurality of suction openings (lateral suction opening and lower suction opening) toward the ejection opening. An air blowing guide member is provided closer to the plurality of suction openings (lateral suction opening and lower suction opening) than to the air blowing fan, inside of the plurality of suction openings (lateral suction opening and lower suction opening). The air blowing guide member guides air introduced into the air blowing passage from the plurality of suction openings (lateral suction opening and lower suction opening) toward the air blowing fan.

摘要： Provided is a suction and separation composite tube, and a suction cleaning machine and a harvesting machine using the same, which are highly cost effective and are capable of, with a relatively simple structure to keep the manufacturing costs low, separating items of relatively small specific gravity from items of relatively large specific gravity even if the output of a motor is set high, and thus reducing the likelihood of clogging or the like of sucked objects and effectively preventing damage to or breakage of a fan and a fan casing. The suction and separation composite tube includes a connecting tube portion, a suction tube portion, and a separation tube portion. The suction tube portion or the separation tube portion is integrally continuous with the connecting tube portion at a distal end thereof. The suction tube portion and the separation tube portion are combined together at an intermediate portion or proximal end portion thereof. Using the fact that the flow velocity of airflow involving sucked objects that have been sucked from a suction port decreases at a combining portion, the sucked objects are separated into items of relatively small specific gravity and items of relatively large specific gravity.

摘要： A Y-shaped air dam with a central frame configured to facilitate the focusing of air from a lawn and leaf blower for the collection of leaves and similar lawn debris into collection containers, exhibiting two panels connected to a central frame. The central frame is equipped with retaining clips configured to facilitate attachment of a collection container such as a paper bag to the central frame securely without tools. The two panels pivot about hinges and may be removed from the central frame for storage or folded up when not in use. Stakes may be used to anchor the panels to the ground during use. A companion device may be included which is configured to perforate collection containers such as bags to provide for the passage of air through the containers during use.

摘要： A single-tube blowing suction device, including a body, an airflow generation apparatus, a collection apparatus, and a blowing-suction tube. The airflow generation apparatus has an air inlet portion and an air outlet portion and is rotatably mounted on the body. The airflow generation apparatus rotates relative to the body to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion is in fluid communication with a first end of the blowing-suction tube, and the air outlet portion is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion is in fluid communication with the first end of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction.

摘要： The present invention provides a blower with reduced noise. The blower comprises a blower main body incorporating a centrifugal fan. The blower main body is configured to suck air from both sides of the blower main body by rotation of the centrifugal fan. The centrifugal fan includes a support plate having a rotation center and a plurality of blades provided on each of a first surface and a second surface of the support plate. A position of at least part of the plurality of blades on the first surface and a position of at least part of the plurality of blades on the second surface are misaligned in a circumferential direction, and/or a number of the plurality of blades on the first surface differs from a number of the plurality of blades on the second surface.
