To [Structure] A vertical wall 6 for partitioning the operating part 4 and the backhoe device 3 is provided, and a transparent part 10 made of a transparent plate member is provided on the vertical wall 6, and a lower side 10a of the transparent part 10 is provided in front. The roof 7 is formed in a downward shape, and the roof 7 is supported on the upper end of the vertical wall 6 in a cantilevered manner, and extends toward the operation unit 4 side.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure near a driving part of a swivel in a backhoe.

[0002]

[Prior art]

 In many small backhoes, in particular, the operating part is located in the center of the swivel base, and the backhoe device (boom base) is connected to the front end of the swivel base. In recent years, by placing the operating unit and the backhoe device (boom base) 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, thereby allowing the swivel base to be moved within a small range. Backhoes configured to rotate have been proposed.

[0003]

[Problems to be solved by the device]

 As described above, when the operating part and the backhoe device (boom base part) are arranged side by side on the swivel base, the bucket at the tip of the arm operates when the boom is placed in a substantially upright position and the arm is operated toward you. Since it is located on the upper side of the section, soil spilled from the bucket may enter the operation section.

In this case, it is conceivable that the operating unit 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. In addition, in the case of a small backhoe that often works in a narrow urban area, when a cabin is provided on the swivel base, the visibility especially near the ground near the backhoe itself becomes narrow. The present invention is a backhoe in which a driver and a backhoe device (boom base) are arranged side by side on a swivel base. In this backhoe, soil spilled from a bucket is secured while ensuring comfort and visibility in the driver. The purpose is to prevent people from getting in.

[0005]

[Means for Solving the Problems]

 The feature of the present invention is that the backhoe as described above is configured as follows. In other words, the operating part and the backhoe device are arranged side by side on the swivel base, and a vertical wall separating the operating part and the backhoe device is provided between the operating part and the backhoe device, so that the backhoe device side can be seen transparently. The vertical wall is provided with a see-through part composed of the plate member, the lower side of the see-through part is formed in a front-down shape, and the roof is cantilevered at the upper end of the vertical wall to extend to the driver's side.

[0006]

[Action]

 [I] With the configuration according to the present invention, the operating section and the backhoe device are partitioned by the vertical wall and the roof. Therefore, when the boom is placed substantially upright and the arm is operated toward the front side, Even if soil spills from the bucket located on the upper side, the soil will not be blocked by the vertical walls and roof and enter the driving section. Even if such a vertical wall and roof are provided, the front and rear of the driving section and the lateral side of the driving section on the side opposite to the backhoe device are open, so that the driver of the driving section may feel pressure. There is no such thing. The driver in the driving unit does not hinder the field of view (especially the field near the ground near the backhoe itself) during work.

[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 backhoe device side is secured, and the operating unit and the backhoe device are secured. The state of can be easily viewed. In this case, since the lower side of the see-through portion of the vertical wall is formed in a front-down shape, it is easy to see the diagonally lower front side of the backhoe device through the vicinity of the lower side of the see-through portion from the driving section. Further, since the transparent portion 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 transparent portion of the vertical wall.

[0008]

[Effect of device]

 As described above, in a backhoe in which the operating part and the backhoe device are arranged side by side on the swivel base, soil spilled from the bucket enters the operating part side while not giving a feeling of pressure to the driver in the operating part. It was possible to prevent the car from coming in and improve comfort in the driving section. And, the front and rear of the driving part, the lateral side opposite to the backhoe device in the driving part is open, and the backhoe device side can be seen through the transparent part of the vertical wall, and the transparent part of the vertical wall. The visibility at the time of work is secured by the fact that the diagonally lower front side of the backhoe device can be easily seen through the vicinity of the lower side, so workability is also sufficient.

【Example】

 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 that the swivel base 2 can be fully swiveled. A driving unit 4 is arranged on one lateral side of the vehicle, and a driving unit 5 accommodating an engine and the like is arranged at the rear of the swivel base 2 to form a backhoe with a dozer.

As shown in FIG. 1 and FIG. 2, a vertical wall 6 is installed between the operation unit 4 and the backhoe device 3 to prevent the dust from splashing, and operation is started from the upper end of the vertical wall 6. A roof 7 is cantilevered above the section 4. On the front side of the operating tower 8 for the traveling device which is erected in front of the operating section 4, there is a handrail 9 for getting on and off, which also serves as a guardrail of the operating tower 8.

A window 10 (corresponding to a see-through portion) made of transparent plastic or tempered glass is provided on the vertical wall 6 so that the backhoe device 3 side can be widely seen from the operating section 4, and a lower side 10 a of the window 10 is provided. It is formed in a front-down shape, and a window 11 for see-through upward is also provided in the front portion of the roof 7. Then, the upper surface of the driving part 5 is formed in a rearward and downward inclined state. With the above configuration, there is nothing that obstructs the field of view when the driver views the rear side from the driving unit 5, so that the field of view of the rear side and the lower rear side is widened. Further, since there are no supporting columns or the like behind the driving unit 4, the driver of the driving unit 4 can easily twist his / her body to look behind.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
