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 (the base of the boom) are arranged side by side on the swivel base, so that the boom is in a substantially upright state 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 (the 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. The present invention relates to a backhoe in which a driving unit and a backhoe device (base of a boom) are arranged side by side on a swivel base, and soil spilled from a bucket enters the driving unit while securing comfort and visibility in the driving 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 driving unit and the backhoe device are arranged side by side on the swivel, and a vertical wall is provided between the driving unit and the backhoe device to partition the driving unit and the backhoe device. It is composed of a pair of front and rear struts erected at both side positions in the front-rear direction of the see-through portion, and a peripheral frame component having a beam portion connected to the upper portions of the two struts on the upper side of the see-through portion. A roof extending to the operation unit side in a cantilever manner is connected to a beam located at the upper end of the vertical wall. [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 window of the vertical wall. [0008] 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 front and back of the driving unit, the point that the lateral side opposite to the backhoe device in the driving unit is open, and that the backhoe device side can be seen through the window of the vertical wall, the visibility at the time of work is secured. Therefore, the workability is also sufficient. 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 operation unit 4 and the backhoe device 3 to prevent the soil from splashing. The roof 7 is cantilevered above the roof 4. A handrail 9 for getting on and off which also serves as a guardrail of the operation tower 8 is arranged in front of an operation tower 8 for a traveling device which is provided upright in front of the operation unit 4. 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 the backhoe device 3 side widely.
A window 11 for upward see-through is also provided on the front side of the roof 7. 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 members standing upright at both side positions in the front-back direction of the window 10. And a peripheral frame component portion having a beam portion connected to the upper portion of the two pillar portions on the upper side of the window 10, and the roof 7 is moved from the beam portion of the vertical wall 6 to the operating portion. It is extended to the 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.
