Description

[Detailed explanation of the invention] (a) Industrial application field This invention cuts grass stems using a cutting blade that rotates inside the casing that makes up the self-propelled machine body, and the cut grass is collected. This invention relates to a device for efficiently performing mowing work while collecting grass clippings in a walking type mower that performs mowing work while collecting grass by feeding it into a catcher detachably installed at the rear of a casing.

(b) Prior Art The above-mentioned walk-behind mower, represented by the lawn mower, is a walk-behind type mower and is small in size, as well as problems with the overall design of the machine, packaging and transportation, and front-to-back balance during work. In this regard, there are restrictions on increasing the size of the catcher attached to the rear of the casing, so the capacity is generally about 60cm.

(c) Problems to be solved by the invention In walk-behind grass mowers, the catcher capacity is limited due to the above-mentioned circumstances, so the catcher becomes full after only a cutting distance of approximately 15 m. Further, when cutting long grass, the above-mentioned working process distance is further reduced.

As a result, it is often necessary to interrupt the cutting operation and transport the grass clippings accumulated in the catcher to a disposal site, resulting in a lot of lost time and inefficiency.

This invention was implemented in view of the above problems, and although it is a walk-behind mower that collects grass clippings into a catcher while mowing, it minimizes work interruption time, reducing loss time and improving efficiency. The purpose is to enable you to work efficiently.

(d) Means for Solving the Problems In order to achieve the above object, the grass clippings collecting device of the grass cutter according to the present invention collects the grass clippings cut and discharged by the cutting blade that rotates inside the casing 1. Catcher 3 detachably attached to the rear
In a walk-behind mower that works while collecting grass by blowing air into the mower, the auxiliary container 6 for transferring and storing the collected grass in the catcher is formed to have a larger volume than the catcher 3, so that the machine body can be improved. It is characterized by being detachably attached to the area directly above it.

(E) (Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Fig. 1 is an overall perspective view of the mower according to the present invention, Figs. 2 and 3 are a side view and a plan view of the same mower, and Figs. 4 to 9 are parts showing the structure of each part of the grass clippings storage device according to the present invention. It is a diagram.

Although illustration of the internal structure of the mower of the embodiment is omitted, the mower is roughly configured as follows.

A prime mover such as an engine is mounted in the inner part surrounded by the bonnet 2 at the top of the bowl-shaped casing 1, and a cutting blade that rotates in conjunction with the output shaft of the prime mover is placed near the lower opening in the casing 1. The mower is arranged so that the cut grass cut by the cutting blade is sent through a weed passage inside the casing to a catcher 3 removably installed at the casing outlet to collect the grass.

The fuselage, which is composed mainly of the casing 1, runs on its own by touching the ground with four running wheels 4, and is operated by a control handle 5 extending rearward from the fuselage for operation and work operation. It has become common for people to reap the crops while doing so.

In the present invention, in the above mower, an auxiliary container 6 separate from the catcher 3 can be attached to and detached from the machine body as required.

The auxiliary container 6 is formed by fixing the upper opening edge of the bag body 7 to the upper frame 8, has a grass cutting capacity larger than that of the catcher 3, and has running wheels 4 arranged at the four corners. The front support 9 and the rear support 10 hold the front support 9 and the rear support 10 directly above the fuselage.

Further, in the attached state, the front end of the auxiliary container 6 including the front support member 9 is recessed by a dimension L from the front end of the fuselage in a side view (FIG. 2), and also includes supports 9 and 10. The upper end is lower than the highest point of the fuselage by dimension H, and furthermore, in plan view (third
In the figure), the width W is such that both ends of the width direction including the supports 9 and 10 are located inward from the maximum left and right width W of the fuselage.
1.

The front support body 9 is formed into a gate shape by bending a pipe material, etc., and has tapered insertion parts 11, 11 at the lower ends of both legs, and the same parts are used as mounting seats 12, 12 mounted on the fuselage. At the same time, there is a support pin 1 at the top.
3 and 13 are installed, and hooks 14 and 14 extending from the upper frame 8 on the side of the auxiliary container 6 are hooked and supported (see FIGS. 4, 5, and 6). ).

A handle 21 is installed on the rear side of the upper frame 8 of the auxiliary container 6, and holes 20, 20 penetrating downward are opened at the bottoms of the mounting seats 12, 12. It is designed to allow water and debris that accumulates to fall off.

The rear support body 10 is formed by bending a spring-acting member into a vertically inverted substantially gate shape, and has recesses at both lower corners that fit into appropriate positions of the operating handle 5. Engaging parts 15, 15 are provided, and shaft parts 18, 18 are provided at the upper part to be inserted into holes 17, 17 of connecting plates 16, 16 installed in the upper frame 8 of the auxiliary container 6. (See Figures 7, 8, and 9).

Note that the shaft parts 18, 18 are inserted into the holes 17, 17 in a freely rotatable state, and the connecting plates 16, 1
Rotation is prevented only when a part of the rear support body 10 is fitted into the stopper notch grooves 19, 19 formed at the rear support body 6, and the rear support body 10 is maintained in an upright position.

In the mower configured as in the embodiment, the front support 9 is installed and erected at the front of the machine body, the hooks 14 of the auxiliary container 6 are hooked to the support pins on the upper part of the front support 9, and the hooks 14, 14 of the auxiliary container 6 are attached to the rear of the auxiliary container 6. The rear supports 10 that are connected are maintained in an upright position,
The entire auxiliary container 6 is rotated downward using the support pin as a rotation fulcrum, and the recess engaging portion 1 at the lower part of the rear support body 10 is rotated downward.
By fitting 5, 15 into the control handle 5, the auxiliary container 6 can be installed on the machine.When mowing a large area, etc., the auxiliary container 6 can be installed as described above. Even when the catcher 3 is full, the grass clippings can be transferred to the auxiliary container 6 and the work can be continued with the catcher 3 empty. This reduces the time lost in having to throw away the grass clippings to the disposal site each time the catcher is full, increasing efficiency. This allows you to work effectively.

Since the auxiliary container 6 is installed directly above the machine body, the machine body will not tilt significantly due to the weight of the stored grass clippings, so the running performance will not be deteriorated due to unbalanced loads, and the cutting height will be reduced. This allows for a good-quality harvest without any unevenness.

(G) Effects of the invention According to the invention, although it is a walk-behind mower that performs mowing work while collecting grass clippings into a catcher, it minimizes the interruption time of work and performs mowing work efficiently with less lost time. be able to.

Since the auxiliary container 6 for transferring and storing the grass clippings accumulated in the catcher 3 is placed directly above the machine body, the weight of the grass clippings stored in the auxiliary container 6 will prevent the machine body from tilting significantly. This has the advantage that it is possible to cut with a good finish without causing problems such as poor running performance due to unbalanced loads or uneven cutting heights.
