Abstract

(57) [Abstract] [Purpose] To provide an operating lever arrangement structure applicable to a micro hydraulic excavator machine. [Structure] When viewed from the rear of the operator seat 3, the operator seat 3 is adjacent to the right side of the operator seat 3 and
Attach the soil discharge plate control lever 4 and the engine throttle lever 5 at substantially the same height as the above, and provide the rods 4a and 5a of a length that is easy for the operator seated on the operator seat 3 to operate. There is. Since the soil discharge plate control lever 4 and the engine throttle lever 5 are arranged on the side of the operator seat 3, there is a space in front of the operator seat 3 in which a normal driving posture can be maintained.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an operating lever arrangement structure.

[0002]

[Prior Art]

 Conventionally, in a small hydraulic excavator machine, as shown in FIGS. 3 and 4, a driver's seat 2 is provided in the front half part of the turning frame 1, and a drain plate control is provided on the front right side of the operator seat 3 of the driver's seat 2. A lever 4 is provided, and an engine throttle lever 5 is provided on the right side of the operator seat 3.

[0003]

[Problems to be solved by the device]

 However, if the above-mentioned arrangement of the operating lever is applied to the driver's seat 2 of the ultra-small hydraulic excavator with a small swing frame 1, obstacles such as contact of the earth plate control lever 4 with the operator's leg occur, and the operator is There was a problem that it was difficult to drive because it forced a cramped driving posture.

In view of the above-mentioned circumstances, the present invention provides a layout structure of an operation lever applicable to a micro hydraulic excavator machine by arranging the earth plate control lever to the side of the operator seat. It was made for the purpose.

[0005]

[Means for Solving the Problems]

 The present invention has a structure in which the soil discharge plate control lever and the engine throttle lever are attached to a predetermined height position near the side of the operator seat.

[0006]

[Action]

 Therefore, in the present invention, since the soil discharge plate control lever and the engine throttle lever are arranged on the side of the operator seat, there is a space in front of the operator seat where a normal driving posture can be maintained.

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing the outline of the arrangement structure of the operating lever of the present invention, and FIG. 2 is a view taken along the line II-II of FIG. In the figure, the same parts as those in FIGS. 3 and 4 are designated by the same reference numerals.

In the present embodiment, the earth plate control lever 4 and the engine throttle lever 5 are provided at a position close to the right side of the operator seat 3 as viewed from the rear of the operator seat 3 and at substantially the same height as the operator seat 3. The rear cover 6 is attached at a predetermined interval, and the rods 4a and 5a having a length that is easy for an operator seated on the operator seat 3 to operate are provided.

The operator sits on the operator seat 3 and operates the levers 4 and 5 with the right hand.

Then, the soil discharge plate control lever 4 is operated to control the soil discharge plate, and the engine throttle lever 5 is operated to control the output of the engine.

According to the arrangement structure of the operation lever of the present embodiment, since the soil discharge plate control lever 4 and the engine throttle lever 5 are arranged on the side of the operator seat 3, the normal operation is performed in front of the operator seat 3. There is a space where you can keep your driving posture.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0014]

[Effect of the device]

 According to the arrangement structure of the operation lever of the present invention, by arranging the soil discharge plate control lever and the engine throttle lever to the side of the operator seat, a space where a normal driving posture can be maintained in front of the operator seat. Therefore, the excellent effect that it can be applied to the driver's seat of an ultra-small hydraulic excavator can be obtained.
