克服するために解決せらるべき技術的問題点が生じてく
るのである。In a conventional walk-behind lawn mower, as shown in FIG. 3 attached to the attached sheet, an engine (2) is mounted on a central upper surface portion of the moody stick (1), and an exhaust port (3) is provided behind the moire stick (1). ) Is provided. A storage bag (4) is attached to the discharge port (3), and the cut grass is discharged from the discharge port (3) and stored in the storage bag (4). However,
The cut grass may stay in the vicinity of the discharge port (3) and cause “clogging”. Especially, when the cut grass contains a large amount of water like wet grass, the cut grass may be removed from the discharge grass (3). It adhered to the inner surface of the and became more likely to cause “clog”. For this reason, it has been proposed that the shape and inclination of the discharge port are variously changed, but none of them can obtain a sufficient discharge effect. Therefore, there arise technical problems that must be solved to overcome these deficiencies.

ものである。This invention has been proposed as a solution to this problem in view of the above problems, and in a walk-behind lawnmower, there are a plurality of discharge ports provided between the cutting blade and the storage bag on the floor surface. Of the sweep floor type discharge port in a walk-behind lawn mower, characterized in that an air passage is provided in the lower part of the floor surface, and the floor surface and the storage bag are connected. It is intended to be provided.

している。According to the present invention, a plurality of air holes are provided on the floor surface of the discharge port of the walk-behind lawn mower, and air is blown in from below the floor surface. This air is sent from the storage bag portion to the lower portion of the floor through the ventilation passage, passes through the plurality of air holes, and is circulated again from the discharge port to the storage bag portion. Therefore, the turfgrass stagnation near the discharge port can be blown off by the wind pressure of the air passing through the air holes, and the turfgrass can be forcibly discharged. Further, since the air passing through the air holes circulates from the storage bag portion through the ventilation passage, it is possible to prevent dust from being generated around the cutting portion.

Is mounted, and a rotary blade (7) which is rotated by the drive of the engine (6) is rotatably attached to the inside of the moody (5). A discharge port (8) is provided at the rear of the moody (5), but is inclined so as to easily discharge the cut grass, and further to the floor surface (9) of the discharge port (8). Multiple air holes (10) (10)…
Has been opened. The air holes (10) (10) ... Are projections having an opening in the rearward direction and are formed by an appropriate means such as press punching. The air holes (10) (10) are not limited to being directed backwards, but may be directed upwards. Even in such a case, the grass that has been cut may have air holes (10) (10).
It is lifted up by the wind pressure from, and obtains the same effects as those described later.

とは当然である。Thus, in this embodiment, the turfgrass mowed by the rotary blade (7) is carried to the discharge port (8) by the discharge wind generated by the rotating fin (not shown). . In the case of dry and light turfgrass, it is blown by the exhaust air as in the conventional type and is stored in the storage bag (12) as it is. Then, the discharged air passes through the mesh of the storage bag (12) and returns to the inside of the box (13) to the ventilation passage (below the floor surface (9) as shown by the arrow in FIG. 14), passes through the air holes (10), (10) ... on the floor surface (9), and again passes through the storage bag (1
It circulates to 2). Here, the relevant moody (5)
When the rotary blade (7) of No. 1 cuts off moist heavy grass, it is easy for the cut grass to stay near the discharge port (8) in the conventional type. Since the air holes (10) (10) of (9) are opened rearward, strong air is blown rearward from the air holes (10) (10) ... and from the rotary blade (7). A strong wind pressure is generated in combination with the exhaust wind of the above, and the mowed turfgrass is forcibly discharged to the rear storage bag (12) without being stagnant in the discharge port (8). Therefore, the occurrence of “clog” at the time of discharging can be eliminated. still,
Although the embodiment of the present invention has a structure as described above, various modifications can be made without departing from the spirit of the present invention, and the present invention naturally extends to it.

のである。As described in detail in the above one embodiment, the present invention provides a "sweep floor type" in which air flows through the air passage from the ventilation passage at the lower part of the floor by providing the air hole in the floor of the outlet. It is one of the outlets. The wind sent from this air hole and the exhaust air from the cutting blade section join together to generate a strong wind pressure, which allows forcibly discharging the grass that has been mowed.For example, it contains a lot of water such as wet grass. Even when
There is no "clog" when discharged. Further, since the wind passing through the air holes is circulated from the storage bag portion, dust will not be generated around the mowing part of the lawn mower, the lawn mowing work will be comfortable, and efficient mowing work will be possible. is there.
