JPH06169624A - Variable collector in lawn mower - Google Patents

Abstract

PURPOSE:To provide the subject collector variable in volume, made up of a width-controllable frame so that the collector to hold cut lawn keeps a container shape and an air-permeable meshy bag fitted so as to cover the frame. CONSTITUTION:A collector 7 in a walking-type lawn mower is so designed that a cut lawn blowing port 13 is provided behind a circular housing covering the outer periphery of rotary cutting edges 5, 6 and cut lawn is held through the port 13, is made up of a frame 14 so that the collector 7 keeps container design and an air-permeable meshy bag 10 fitted so as to cover the frame 14. Holding parts 11 to fit the housing by hooking on the upper part of the rear of the frame 14 are provided at the front and of the frame 14, the center of the top surface of the frame 14 is fitted with a grip 15, and two pipes 8 are fitted on the upper part of the frame 14 at a longitudinal interval and ensured to be slidably threaded with a controlling member 9 bent in a horizontally U shaped fashion when viewed from above, thus making the width of the frame 14 controllable laterally.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a collector in a lawnmower.

[0002]

2. Description of the Related Art A conventional lawn mower collector has a box shape,
The entire circumference is made of a breathable mesh, and moreover,
The size of the box-shaped container was constant.

[0003]

The collector is preferably large in view of work efficiency, but in a narrow space, the collector is too large than necessary, and thus it becomes bulky. On the other hand, if the collector is made small, when performing lawn mowing work in a large area, the work will quickly become full and the contents inside will have to be discarded, and the work will have to be interrupted many times. is there.

The present invention is an improvement over conventional collectors,
The purpose is to eliminate the above-mentioned problems.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, in a walk-behind lawn mower in which a lawn outlet is formed in the rear of a circular housing that covers the outer circumference of a rotating cutting blade, and a collector for storing cut grass is detachably attached to the lawn outlet. Consists of a frame that holds the shape of the container and a mesh bag that is breathable and is installed so as to cover the frame, and part of the frame that constitutes the collector is configured so that the width can be adjusted in the lateral direction. The lawn mower is characterized by a variable collector configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below with reference to the drawings. FIG. 1 shows a housing 1 provided with a pair of front and rear wheels 2. An engine 3 is mounted on the upper surface of the housing 1, and a lawn mowing blade 12 housed in the housing 1 is rotationally driven by rotational power of the engine 3. I am trying to do it. Housing 1
A blow-out port 13 for discharging the cut grass is provided at the rear end, and a collector 7 is attached to the blow-out opening 13 to collect the cut grass.

As shown in FIG. 7, the collector 7 comprises a frame 14 for holding the shape of the container and a breathable mesh bag 10 mounted so as to cover the frame 14, and a housing is provided at the front end of the frame 14. 1 There is a locking portion 11 for hooking and attaching to the upper rear end, and a handle 15 is attached to the center of the upper surface of the frame 14. Further, on the upper part of the frame 14, two pipes 8 which are provided apart from each other in the front-rear direction are slidably inserted into an adjusting member 9 which is bent in a U-shape when viewed from above.

Further, the bag 10 of the collector 7 has an accordion-like slack so that the bag 10 expands to the left and right as the U-shaped adjustment member 9 expands and contracts as shown in FIG. In this state, the mesh-shaped bag 10 is stretched to the maximum, and the volume of the collector 7 is maximized. Further, the lawn mowing blades 5 and 6 attached to the lower portion of the drive shaft 4 of the engine 3 are 2 in this embodiment.
There are two blades, and the two blades are attached in a cross shape when viewed from below as shown in FIG. Each blade 5 and 6 has a blade portion 5a,
6a and an air blower 5b for blowing off the cut grass,
6b, and the positional relationship between the upper and lower blades 5 and 6 is configured as shown in FIG. That is, the blade portion 6 of the blade 6
The positional relationship between the blade portions 5a and 6a is set such that the tip portion of the blade portion 5a of the upper blade 5 is lower than the straight line connecting the tip portion of the a and the rear end of the air blasting portion 6b.

With this construction, the grass cut by the lower blade 6a can be smoothly delivered to the upper blade 6b, and the cut grass can be satisfactorily discharged to the outside of the housing 1. There are features. Also, the blade portions 5a, 6a
Since it has a two-blade structure, the rotation of the drive shaft 4 can be reduced and noise can be reduced as compared with the case of rotating one cutting blade.

[0010]

According to the present invention, when the lawn mowing work is performed in a wide area or when picking up a large amount of one leaf such as a fallen leaf, the frame should be extended to increase the collector volume. You don't have to throw away the grass you have cut many times, so you can perform efficient lawn mowing work.
Also, when performing lawn mowing work in a narrow place, the collector can be compactly stored and the machine can be easily attached and detached by returning the frame to its original state.
