Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a walk-behind lawn mower having a grass collection container disposed on the rear side of a cutting blade housing.

[Conventional technology]

In the above-mentioned walk-behind lawn mower, conventionally, for example,
As shown in Japanese Patent No. 6g788, the control handle is connected to the cutting blade nozzle, which often causes the following disadvantages.

[Problem that the invention seeks to solve]

In other words, in order to increase the collectible capacity of the grass collection container,
Collection! If 1 is made such that the upper and lower middle portions are larger than the upper and lower middle portions of the cutting blade housing and protrudes upward from the cutting blade housing, or the width is larger than the width of the cutting blade housing and protrudes laterally outward from the cutting blade housing, Since it is necessary to prevent the operation handle from interfering with the grass collection container, it is necessary to provide the operation handle with a part that bends from the connecting part to the cutting blade housing to bypass the grass collection container laterally outward or upward. As a result, the control handle becomes a double-whipped one,
It became necessary to provide a relay connecting member for connecting the cutting blade housing and the operating handle in place of the bent portion of the handle, making the structure for connecting the handle complicated.

An object of the present invention is to provide a control handle and a connection ar
The purpose is to simplify any t of I<.

[Means for solving problems]

The walk-behind lawn mower according to the present invention is characterized in that a cylindrical body forming a grass supply path from the cutting blade hacking to the grass collection container disposed on the rear side thereof is attached to the cutting blade hacking. The operation handle is connected to the above (9), and its functions and effects are as follows.

[For production]

In addition to providing the above-mentioned cylindrical body, by connecting the control handle to this (9), it is possible to make the grass collection container larger in the upper and lower part of the area that protrudes above the cutting blades, or when it is placed laterally than the cutting blades. The width of the part that protrudes outward is large.
Even if the steering handle is made of a simple shape that does not have a bypass part for the grass collection container, it is also possible to connect the steering handle directly to the above (9) or form a connecting seat. Even if the connection between the handle and the cylindrical body is simple, such as through a connector, the cylindrical body can be used as a relay connection member to avoid interference between the operating handle and the grass container. The handle can be connected to the cutting blade without touching the grass collection container.

〔Effect of the invention〕

By increasing the capacity of the grass collection container, it is possible to simplify the operating handle itself and the structure for connecting the handle, and it is possible to store and collect a large amount of grass debris. It has become possible to obtain a handle structure that is simple and inexpensive, allowing for efficient work by reducing the number of work interruptions required for turf discharge.

〔Example〕

The present invention can also be applied to a hand-pull type in which both the front and rear wheels are idle wheels.
