Description

[Detailed Description of the Invention] The present invention has a shovel mounted on an arm that can be driven and swung vertically so that the angle of elevation and elevation can be changed freely, and a collect link that keeps the ground attitude of the shovel constant when the arm swings. Regarding excavator work vehicles.

The present invention was devised for the purpose of simplifying the structure for preventing the collect link from being removed in the above-mentioned type of excavator vehicle. Fix the light mounting parts,
The attachment member is characterized in that it also serves as a member for preventing removal of the collect link.

In other words, by adopting a rational structure in which the headlight mounting member is attached to the fixed pivot shaft for the link to the collector, the mounting member can be used to prevent the collector link from being removed from the shaft. As a result, it is possible to eliminate the need for a special member to prevent the collect link from being removed from the shaft as in the past.
The removal prevention structure has been simplified, and members can be omitted.

Hereinafter, embodiments of the present invention will be described in detail based on illustrative drawings.

A transport device 2 for scooping up, transporting and discharging earth and sand while traveling is provided at the front of a traveling machine base equipped with a tire-type traveling device 1, and on the other hand, an excavation device 3 for ground excavation work is provided at the rear. The driver's seat 4 is rotatably provided between 2 and 3 so as to face both the front and rear of the aircraft.
A first operating section 5 for operating the traveling device 1 and the transporting device 2 is disposed in front of the vehicle, and a second operating section 6 for operating the excavating device 3 is disposed at the rear of the vehicle. The device 1 and both working devices 2 and 3 are configured to be driven by hydraulic pressure, which is an example of a fluid pressure type, and the excavator vehicle is configured so that it can perform both transportation and excavation operations with a single device. It is.

The transport device 2 is a bracket installed at the front of the traveling machine stand)
- The shovel 9 is pivotally connected to the tip of an arm 8.8 which is pivotally connected to the arm 7 so as to be able to swing up and down.

The lift cylinder 1 extends between the traveling machine base and the arm 8.
0 is interposed therebetween, and is configured to drive and oscillate the arm 8.

A center-folded first
The link members 11 are pivotally connected to each other, and on the other hand, there is a second link member on the proximal end side of the arm 8, one end of which is pivotally fixed to the bracket 7.
The link members 12 are pivotally connected, and both link members 11.12
A tilt cylinder 13 is interposed in between, and when the tilt cylinder 13 is at almost the end of the stroke on the contraction side,
A substantially parallel four-speed link mechanism is formed by both link members 11 and 12, the arm 8, and the tilt cylinder 13, and even if the arm 8 is swung up and down, the excavator 9 is collected so that the ground attitude remains almost constant. In addition to forming a link 14, the tilt cylinder 13 is configured to drive and oscillate the excavator 9.

The second link member 12 is fixed at one end by being pivotally supported on a shaft 15 which is connected to the bracket 7 so as to protrude laterally and outwardly.

A mounting member 16 is screwed onto the tip of the shaft 15, and this mounting member 16 prevents the second link member 12 from being removed from the shaft 15. A lighting box 20, which includes a headlamp 17, a flasher lamp 18, and a rearview mirror 19, is attached to the vehicle.

The mounting member 16 is not limited to the mounting member 16 to which the lighting box 20 as in the above embodiment is mounted, but may be any mounting member to which at least the headlamp 17 can be mounted.
