BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a backhoe near a driving part of a turntable.

[0002]

2. Description of the Related Art In particular, there are many small backhoes in which an operating section is arranged at the left and right center of a swivel and a backhoe device (boom base) is connected to the front end of the swivel.
In recent years, by arranging the operating unit and the backhoe device (base of the boom) side by side on the swivel base, the boom is placed in a substantially upright position and the arm is operated toward the front side to swivel the swivel base within a small range. Backhoes configured to do this have been proposed.

[0003]

As described above, when the operating unit and the backhoe device (the base of the boom) are arranged side by side on the swivel base, when the boom is in a substantially upright state and the arm is operated to the front side, Since the bucket at the tip of the arm is located on the lateral upper side of the driving section, soil spilled from the bucket may enter the driving section side.

In this case, it is conceivable that the operating section is covered with a cabin in a substantially closed chamber. However, especially in the case of a small backhoe, the swivel base has a small space. It becomes small and gives a feeling of pressure to the driver in the cabin. Further, in the case of a small backhoe that often works in a narrow urban area, when the cabin is provided on the swivel base, the visibility near the ground, especially near the backhoe itself, becomes narrow. The present invention is a backhoe in which a driving unit and a backhoe device (boom base) are arranged side by side on a swivel base, and soil spilled from a bucket enters the driving unit side while ensuring comfort and visibility in the driving unit. The purpose is to prevent coming out.

[0005]

A feature of the present invention is that the backhoe as described above is configured as follows. That is, the operating unit and the backhoe device are arranged side by side on the swivel base, and a vertical wall that partitions the operating unit and the backhoe device is provided between the operating unit and the backhoe device, and a vertical wall is provided at the front of the operating unit. A transparent portion formed by a transparent plate member capable of seeing through the backhoe device side by connecting a handrail to the front part of the backhoe device and the front part of the vertical wall on the side opposite to the backhoe device. Is provided on the vertical wall, and the roof is cantilevered at the upper end of the vertical wall and extends to the driver's side.

[0006]

[I] With the configuration of the present invention, since the operating unit and the backhoe device are partitioned by the vertical wall and the roof, when the boom is placed in a substantially upright state and the arm is operated toward the front side, the operation is performed. Even if soil spills from the bucket located on the upper side of the part,
This soil will not be blocked by the vertical walls and roof and will not enter the driver's side. Even if such a vertical wall and roof are provided, the front and rear of the driver's part and the lateral side of the driver's part opposite to the backhoe device are open, so that the driver of the driver's part feels oppressive. There is no such thing. Further, the driver in the driving unit does not hinder the field of view during work (particularly, the field of view near the ground near the backhoe itself).

[II] Since the see-through portion is formed on the vertical wall that separates the operating unit and the backhoe device, the lateral view from the operating unit to the side of the backhoe device is ensured, and the operating unit can control the backhoe device. The state etc. can be visually checked easily. In this case, since the see-through part of the vertical wall is made of a transparent plate member, the soil spilled from the bucket does not enter the driving section side through the see-through part of the vertical wall.

[III] When a handrail such as that of the present invention is provided, holding the handrail allows the swivel base to easily get in and out of the operating section. In this case, since the handrail is erected and connected across the front portion of the vertical wall and the swivel base, the front portion of the vertical wall is reinforced by the handrail, and the handrail protects the front portion of the driver. It also becomes.

[0009]

As described above, in the backhoe in which the operating unit and the backhoe device are arranged side by side on the swivel base as described above,
It is possible to prevent dirt spilled from the bucket from entering the driver's side while not giving a feeling of pressure to the driver in the driver's seat, and to improve comfort in the driver's part. did it. And, in front of and behind the driver,
Since the lateral side of the driver's side opposite to the backhoe device is open and the backhoe device can be seen through the see-through part of the vertical wall, the field of view during work is secured, so workability is also sufficient. It has become. or,
Since the handrail for getting on and off is also used as the reinforcing member at the front part of the vertical wall and the protecting member at the front part of the driving part, it is advantageous in terms of simplification and weight saving of the structure.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a swivel base 2 is attached to a crawler-type traveling platform 1 with a dozer so as to be fully swivelable, and the base of a backhoe device 3 is connected to the left and right center portions of the swivel base 2 to form a swivel base 2. A backhoe with a dozer is configured by arranging an operating unit 4 on one lateral side and arranging a driving unit 5 accommodating an engine and the like at the rear of the swivel base 2.

As shown in FIGS. 1 and 2, a vertical wall 6 is provided between the operating unit 4 and the backhoe unit 3 for preventing dust from being splashed.
The roof 7 is supported in a cantilever manner from the upper end of the vertical wall 6 to above the operation unit 4. This operation tower 8 is provided in front of the operation tower 8 for the traveling device which is erected in front of the operation unit 4.
The handrail 9 for getting on and off, which also serves as a guardrail, is erected between the front portion of the vertical wall 6 and the swivel base 2 on the side opposite to the backhoe device 3 and the front portion of the vertical wall 6. .

On the vertical wall 6, from the driver section 4 to the backhoe device 3
A window 10 (corresponding to a see-through portion) made of transparent plastic or tempered glass is provided so that the side can be widely seen, and a window 11 for see-through upward is also provided on the front portion of the roof 7. Then, the upper surface of the driving portion 5 is configured to be inclined rearward and downward. With the configuration described above, there is nothing that obstructs the field of view when looking backward from the driving unit 5, so that the field of view behind and behind the rear is widened. Further, since there is no member such as a pillar behind the driving unit 4, the driver of the driving unit 4 can easily twist his / her body to look behind.

In order to make the comparison with the drawings convenient, reference is made to the claims of the utility model registration, but the present invention is not limited to the structure of the accompanying drawings by the entry.
