多くの問題が生ずる。Air cushion lawn mowers are already known and usually have a hood supporting an electric motor or combustion engine. The fan forms an air cushion on the underside of the hood by drawing air from the atmosphere through the central hole into the hood. The lower end of the shaft is equipped with a blade for cutting grass. British Patent No. 7. ! No. 21 and British Patent Application No. 1 2,0/7. It is already known to equip lawn mowers of this type with a grass container, as seen in Da 73. The device described in the said patent application has been shown to work satisfactorily, in which a portion of the air is air-cooked in order to transfer the cuttings from the working area of the blades to the harvest bin. B/, which poses a number of problems.

これらの問題は芝刈機を特別な形状に構成することＫよ

四つの仙１ｓのうちの三つの＠部にそって延びている。The weed receptacle ii consists in this embodiment of a bag 2j, which is made of flexible material 21Fi and has an inlet opening λ6, which opening 4 is bent by a rigid connecting part and is not used for mowing. The exit opening of the machine is fixed at %/j. Also bag-2j
is separated from the lower part 21 by a horizontal plane 27, which part t is provided with a circumferential lip 13 of the mower in four different ways. The lip λ extends along three of the four sides 1s of the bag λj.

する。When the bag 2j is connected to the mower, the lower side of the horizontal core and the rear lip of the mower and the lower part of the weed bag 2j
A chamber 30 is formed between the lip 2 and the lip 2t. The horizontal surface 27Fi is provided with several openings or holes 31, which allow air to pass from the weed bag λj to the chamber 30.

草刈機は通常では、図示されていないハフドルやモータ

However, this action is further promoted by the air pressure sucked into the food saw by the fan wheel JO, and as a result, the grass cut by the blade is collected and passed through the outlet opening IS to the grass collecting bag. ! sent inside. Inside the weed collection bag-2j, the air flows downward and passes through the hole 3/ into the chamber 3071, leaving the cut grass on the horizontal surface 127. At the same time, the air flows under the rear of the lip/j. The air flowing out from the hood/J on the side is fed into the air compartment of the weed bag 2j.Therefore, an air cushion is formed in the chamber 30 that floats together with the weed bag 2jt. :2! When the cut grass continues to have a light weight I, the hole 3/ in the horizontal plane -27 is closed, so that the air flowing in from the air cushion together with the cut grass reaches the chamber 30 [7]. Therefore, the air cushion below the housing 4'9.2j is mainly formed by the air flow entering from the rear of the lip 13.

It can also be adopted. In addition, the top of the harvesting container is provided with an opening that allows air to escape to the atmosphere, and this type of air leakage has a slight effect on the air cushion. It is also possible to improve the J- transfer to the container.
