Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a awning device for a walking type working machine in which an operator walks following a working machine while holding a grip portion of a handle.

[0002]

2. Description of the Related Art Among work machines such as a cultivator, there are a riding work machine in which a worker works while standing on a vehicle body and a walking work machine in which a worker works while following the work machine on foot. . Some riding-type working machines have a roof on the vehicle body to protect the workers from direct sunlight, while none of the walking-type working machines have a roof.

[0003] Here, the walking-type working machine, like the riding-type working machine, performs most of the work outdoors, so that it is frequently used in fine weather. In particular, when performing tillage work with a walking tiller, work in fine weather is preferred. The reason is that by performing the tillage work in fine weather, the soil can be efficiently turned upside down (replacement of the topsoil and the subsoil is reversed). By turning the soil upside down, air can be included in the soil to make it easier for microorganisms to proliferate, and the soil can be improved so that the crop grows well. Therefore, it is important to efficiently turn the soil upside down.

[0004]

However, when the tilling work is performed in fine weather, the worker is exposed to direct sunlight from the sun, and is easily fatigued. For this reason, it is necessary to shorten the work time and increase the frequency of taking a break in a time zone where the sunlight is strong. Therefore, it is difficult to increase the efficiency of the tilling work.

[0005] In addition, a walking-type work machine such as a walk-behind cultivator can be easily used by a woman because it is a light-weight small-sized work machine. Therefore, women frequently use the walk-behind work machine. Here, preventing sunburn is an important issue for women, but it is difficult to prevent sunburn because walking-type working machines do not have sunshades. For this reason, practical use of a walk-behind work machine capable of preventing workers from being exposed to direct sunlight during work and reducing the fatigue and sunburn of the workers is desired.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a awning device for a walk-behind working machine, which can prevent the worker from being exposed to direct sunlight.

[0007]

According to one aspect of the present invention, a grip is provided at an end of a handle that extends rearward and upward from the body, and a worker holds the grip while holding the grip. In a walking type work machine that walks following
A support frame is attached to the handle with a fixture, and a sunshade is provided on the support frame, so that the sunshade is disposed above the worker's head.

[0008] A support frame is attached to the handle, and a sunshade is provided on the support frame, so that the sunshade is arranged above the operator's head. For this reason, direct sunlight of the sun can be blocked by the sunshade, so that the worker can be prevented from being exposed to direct sunlight.

According to a second aspect of the present invention, there is provided a contact portion for applying the support frame to the handle, and a leg portion extending upward from the contact portion.
And a roof portion extending from the legs to above the operator's head.To attach the support frame to the handle, the contact portion is fixed to the handle with the fixture, and the sunshade portion is provided on the support frame. The awning is attached to at least the roof of the support frame.

Since the support frame is formed integrally with the contact portion, the leg portion and the roof portion, the structure of the support frame can be simplified and the weight can be reduced. Therefore, even if the support frame is attached to the handle, it is possible to prevent an excessive load from being applied to the handle. Furthermore, by making the support frame a simple configuration, the cost of the support frame can be reduced. In addition, a sunshade was attached to at least the roof of the support frame. Therefore, the workability can be satisfactorily secured without obstructing the front view of the worker.

According to a third aspect of the present invention, the fixing device is characterized in that the contact portion is configured to be fixed at an arbitrary position on the handle in order to adjust the height of the roof portion.

The contact portion is fixed to an arbitrary position of the handle by the fixture. Therefore, the height of the roof part can be adjusted by changing the fixing position of the contact part. For this reason, the height of the sunshade can be adjusted according to the height of the worker, so that direct sunlight from the sun can be efficiently blocked, and the worker's working posture can be maintained in a good state.
