Description

[Detailed Description of the Invention] The present invention relates to a construction vehicle, and more particularly to a device for cleaning the operating section of a steering device.

A construction vehicle is equipped with a steering device inside the rear of the vehicle body, an operation section at the rear upper part, and a steering lever provided at the front of the vehicle body and the operation section connected via a link mechanism such as a rod. The vehicle is configured to control steering by operating a steering lever, and a fuel tank is attached to the rear of the vehicle body via a fender to cover the operating section.

In such construction vehicles, slag processing work,
When working in dusty areas, a significant amount of dust accumulates on the vehicle body, and a large amount of dust accumulates especially near the operation parts, causing malfunction of the link mechanism and operation parts, making it impossible to steer the vehicle. It is dangerous.

To prevent this, you can periodically clean the area near the control unit, but since the fuel tank is installed above the control unit, the fuel tank must be removed to clean it. The problem is that the work becomes very troublesome.

The present invention was devised in view of the above circumstances, and its purpose is to provide a construction vehicle in which the vicinity of the operating section can be easily cleaned without removing the fuel tank.

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

A sprocket 2 is provided at the rear of the vehicle body 1, and an idler 3 is provided at the front of a truck frame (not shown) attached to the vehicle body 1, and a track 4 is wound around the sprocket 2 and the idler 3.
An engine 5, a driver's seat 6, an operating lever 7, etc. are provided at the front of the vehicle body 1, and a fuel tank 8 is mounted at the rear.

FIG. 2 is a detailed view of the rear part of the vehicle main body 1. A steering device 9 is installed inside the rear of the vehicle main body 1, and its operating section 10 is provided on the top surface 1a. is connected to the operating lever 7 via a link mechanism 12, and a fuel tank 8 is mounted on fenders 13, 13 attached to both side walls 1b, 1b of the vehicle main body 1, and the fender 1
A support 14 is horizontally fixed across between 3 and 13.

The support 14 is a hollow elongated member, and is bolted to the fender 13 via a bracket 15, and one of the brackets 15 is formed with a screw hole 16 for attaching a coupler.
Insert the coupler 18 from the hole 17 of one fender 13.
are screwed together, and a coupler 19a of an air hose 19 connected to an external air supply source is screwed to the coupler 18, and air is supplied into the support 14.

The support 14 is provided with a plurality of air outlets 20 facing the operating section 10 and spaced apart from each other in the longitudinal direction.

As shown in FIGS. 4 and 5, the air outlet 20 has a hole 14b formed in the lower wall 14a of the support 14, and an air outlet guide 2 is provided around the hole 14b.
1 is attached.

In addition, as shown in Figures 6 and 7, support 1
A hole 14b is bored in the lower wall 14a of 4, and this hole 14
It is also possible to have a shape in which the pipe 22 is inserted and fixed in b.

Since the air is ejected from the air outlet 20 of the support 14 and blows off the dust accumulated on the operation part 10, the dust does not accumulate on the operation part 10 and cause malfunction, which prevents the steering from being impossible.

Since the present invention is configured as described above, it is possible to blow away and clean the dust accumulated near the operating part 10 without removing the fuel tank 8, and even when performing slag treatment work or work in dusty areas, the area near the operating part 10 can be cleaned. This prevents dust from accumulating on the steering wheel, and prevents malfunctions and inability to steer.
