In such a lawn mower, the cut grass is generally discharged through a discharge pipe connected to an opening of the housing by wind force generated by rotation of the cutting blade. The reason why the opening is formed near the outer periphery of the ceiling of the housing is that most of the cut grass flows near the outer periphery of the housing in the direction along the rotational direction of the cutting blade due to the centrifugal force caused by the rotation of the cutting blade. This is to do so.

As described above, the discharge pipe 1 is attached to the terminal end of the opening 100b.
If there is a relatively sharp corner 102 formed by connecting the vertical wall 101a of 01 and the ceiling 100a of the housing 100 in a substantially orthogonal state, the grass clippings flowing toward the discharge pipe 101 and the housing The cut grass flowing inside the corner 102
Once it gets caught on the
There was a risk that the room would be clogged.

In the lawn mowing device according to the present invention, in the above-mentioned structure, at least a portion of the mouth edge corresponding to the lower side in the direction of rotation of the cutting blade, of the vertical wall portion of the discharge tube continuous to the mouth edge of the opening. A characteristic feature is that the inner surfaces of the continuous vertical wall portions are formed into sloped surfaces that intersect with the ceiling portion with a gently sloped slope.
かかる特徴構成による作用・効果は次の通りで
ある。 The functions and effects of this characteristic configuration are as follows.
すなわち、排出筒の縦壁部と、天井部との連結

In other words, the connecting portion between the vertical wall of the discharge pipe and the ceiling has a widening shape with respect to the ceiling, at least at the rim of the opening in the ceiling, which corresponds to the lower side in the direction of rotation of the cutting blade. Since the slopes are formed with gently intersecting slopes, even if the cut grass flowing inside the housing collides with the vertical wall of the outlet at the mouth edge, it will not be cut by the wide slope. The flow is guided downward on the downstream side in the direction of blade rotation.
したがつて、排出筒に向つて流動する刈芝やハ
ウジング内を流動する刈芝が排出筒の縦壁部とハ
ウジングの天井部との接続部に引つ掛かつて付着
堆積することを抑制できるので、排出筒が詰まる

Therefore, it is possible to prevent the grass clippings flowing towards the discharge pipe and the grass clippings flowing inside the housing from getting caught in the connection between the vertical wall of the discharge pipe and the ceiling of the housing and accumulating. This prevents the discharge tube from becoming clogged and allows the cut grass to flow smoothly.
