Description of the Related Art Many small backhoes, in particular, have a driving unit disposed in the center of the turntable on the left and right sides and a backhoe device (base of a boom) connected to the front end of the turntable. In recent years, the operating unit and the backhoe device (base of the boom) are arranged side by side on the swivel base, so that the boom is substantially upright and the arm is operated to the front side, thereby turning the swivel base in a small range. A backhoe configured to cause the backhoe has been proposed. [0003] As described above, when the driving unit and the backhoe device (base of the boom) are arranged side by side on the swivel base, the boom is set in a substantially upright state, and the arm is moved toward the front. When the operation is performed, the bucket at the tip of the arm is located on the lateral upper side of the driving unit, so that the soil spilled from the bucket may enter the driving unit. [0004] In this case, it is conceivable that the operating unit is covered in a substantially closed room shape by a cabin. However, particularly in the case of a small backhoe, the space of the swivel base is small. It becomes small and gives a feeling of oppression to the driver in the cabin. In addition, in the case of a small backhoe that often performs work in a narrow city area, if a cabin is provided on the swivel base, the field of view particularly near the ground near the backhoe itself becomes narrow. In the present invention, in a backhoe in which an operating unit and a backhoe device (base of a boom) are arranged side by side on a swivel base, soil spilled from a bucket enters the operating unit while ensuring comfort and visibility in the operating unit. The purpose is to prevent them from coming out. A feature of the present invention resides in the following configuration of the above-described backhoe. That is, the operating unit and the backhoe device are arranged side by side on the swivel table, and a vertical wall is provided between the operating unit and the backhoe device to partition the operating unit and the backhoe device. A driving unit, comprising: a transparent portion configured by a transparent plate member capable of seeing through; and a peripheral frame component portion including a pair of front and rear support portions that are erected at both side positions in the front-rear direction of the transparent portion. In the front part of the vertical wall, a handrail is erected and connected across a part of the swivel table opposite to the backhoe device with respect to the front part of the vertical wall and a support part of the front part of the vertical wall, The roof is supported in a cantilever manner on the upper end of the vehicle, and extends toward the driving section. [I] With the configuration according to the present invention, since the driving unit and the backhoe device are separated by the vertical wall and the roof, when the boom is substantially upright and the arm is operated to the front side Even if the soil spills from the bucket located on the upper side of the driving unit, the soil is not blocked by the vertical walls and the roof, and does not enter the driving unit. Even if such a vertical wall and a roof are provided, the front and rear of the driving unit and the lateral side opposite to the backhoe device in the driving unit are open, so that the driver of the driving unit may feel a feeling of oppression. Never. Then, the field of view during the operation (particularly the field of view near the ground near the backhoe itself) is not obstructed for the driver of the driving unit. [II] Since the see-through portion is formed on the vertical wall separating the operating portion and the backhoe device, the field of view on the side of the backhoe device side from the operating portion is also ensured. The state and the like can be easily observed. In this case, since the see-through portion of the vertical wall is formed of a transparent plate member, the soil spilled from the bucket does not enter the driving section through the see-through portion of the vertical wall. [III] Then, when a handrail as in the present invention is provided, by having this handrail,
Getting on and off the driving section of the turntable can be performed easily. In this case, since the handrail is erected and connected between the front part of the vertical wall and the swivel base,
The handrail reinforces the front part of the vertical wall, and the handrail also serves as a protection member for the front part of the driving unit. As described above, in the backhoe in which the driving unit and the backhoe device are arranged side by side on the swivel table, the soil spilled from the bucket while not giving a feeling of oppression to the driver of the driving unit. Can be prevented from entering the driving unit side,
The comfort in the driving section was improved. And, the visibility at the time of work is secured by the fact that the front and rear of the driving unit, the lateral side opposite to the backhoe device in the driving unit is open, and the backhoe device side can be seen through the see-through portion of the vertical wall. As a result, workability is also sufficient. In addition, the handrail for getting on and off is also used as a reinforcing member at the front part of the vertical wall and a protection member at the front part of the driving part, which is advantageous in terms of simplification of the structure and weight reduction. An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a swivel 2 is attached to a crawler-type traveling machine base 1 with a dozer so as to be able to fully swivel, and a base of a backhoe device 3 is connected to the left and right central portions of the swivel 2. A driving unit 4 is disposed on one side of the side, and a driving unit 5 containing an engine and the like is disposed at the rear of the swivel 2 to form a backhoe with a dozer. As shown in FIGS. 1 and 2, a vertical wall 6 is provided between the operating unit 4 and the backhoe device 3 to prevent the soil from splashing. The roof 7 is cantilevered above the roof 4. On the front side of the operating tower 8 for the traveling device, which is erected in front of the operating unit 4, a handrail 9 for getting on and off which also serves as a guard rail of the operating tower 8 is attached to the vertical wall 6.
Of the swivel 2 opposite to the backhoe device 3 and the front of the vertical wall 6. The vertical wall 6 is provided with a window 10 (corresponding to a see-through portion) made of transparent plastic or tempered glass so that the driver 4 can see through the backhoe device 3 side widely. Also has a window 11 for upper see-through. In other words, the vertical wall 6 has a window 10 as a see-through portion formed of a transparent plate member that can see through the backhoe device 3 side, and a pair of front and rear stands upright at both side positions in the front-rear direction of the window 10. And a peripheral frame component having a beam portion on the upper side of the window 10 and connected to the upper portions of the two support portions. The roof 7 has a vertical wall 6.
From the beam section to the operation section 4 side. The upper surface of the driving unit 5 is configured to be inclined backward and downward. With the above configuration, there is nothing obstructing the field of view when viewing the rear from the driving unit 5, so that the fields of view behind and below the rear are widened. Since there is no member such as a support behind the driving unit 4, the driving unit 4
The driver can easily twist and look backward. In the claims of the utility model registration, reference numerals are written for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
