Description

[Detailed description of the invention] The present invention provides a safety bar for closing the passageway for boarding and disembarking the open type driving section so as to be able to swing open and close, and a holo type cabin for the said driving section to be detachably attached. Regarding the driving part structure of the working vehicle, by effectively utilizing the original structure,
The purpose is to allow cabins to be installed at low cost.

Next, embodiments of the present invention will be described based on illustrative drawings.

An open driving section 2 and a driving section 3 are provided at the front of a wheeled traveling machine base 1, and a loading platform 4 is provided at the rear thereof to constitute a transport vehicle.

On each of the left and right rear wheels 5 and 5 of the double tire type, the second
As shown in FIG. 3 and FIG. 3, a ring 7 is rotatably attached to a disc 6 of a wheel 5 disposed on the outside of the vehicle body, and a ring 7 is rotatably attached to a disc 6 of a wheel 5 disposed on the outside of the vehicle body. A tightening screw 8 is provided on the disk 6, and a pawl 9 acting on the wheel 5 is attached to the ring 7 by a bent link mechanism 10.
The bolt 11 is attached so as to be switchable between a used state taken out outside and a stored state located inside the wheel 5, and is inserted into the pawl 9 and screwed into the ring 7 when the pawl 9 is in the stored state. Therefore, no matter what mounting position the pawl 9 is in with respect to the wheel 5 when the vehicle is stopped, it can be moved to a usable mounting position by rotating the ring 7. In addition to being adjustable, the pawl 5 can be switched between the use state and the stored state by simply putting it in and taking it out from the wheel 5, so that the work of mounting and storing the pawl 5 can be done easily and quickly.

As shown in FIG. 4, the driving section 2 is configured such that a pair of right and left passageways 12 and 12 are provided with safety rods 13 that can swing open and close to close them. An engine bonnet 15 that can swing up and down relative to the driving section 3 is provided on the side, and a safety guard 16 is provided behind the driver's seat 14.

As shown in FIG. 5, the bending/extending link 17 installed across the bonnet 15 and the vehicle body is configured to be in an extended state when the bonnet 15 is open and to be in a bent state when the bonnet 15 is closed. A sliding fixture 18 for locking the link 17 in the extended state is detachably attached to the bending part of the link 17, and the bonnet 15 is swung into the open state by the tension of the bending link 17 that is fixed in the extended state. It is designed so that it can be locked automatically.

As shown in FIGS. 5 and 6, a hook 19 for locking the bonnet 15 in the closed state is swung between an activated state and a released state around a support shaft 22 by an operating tool 21 on a bonnet mounting base 20. The bonnet is mounted so that it can be switched, is biased to swing into the operating state by the spring 23, and is formed with a cam portion on the hook 19 for swinging when it hits the bonnet 15 that has been lowered. Simply push down the hook 15 to the closed position and the hook 19
is configured to automatically engage.

Further, the spring 24 provided on the mounting base 20 is compressed and elastically deformed by the bonnet 15 that is locked closed, and when the hook 19 is released, the bonnet 15 is raised by the spring 24. At the same time, the lowering is prevented, and the hook 19 is prevented from engaging.

Each of the safety rods 13 is configured to be swingable in a vertical position projecting upward from the vehicle body, and a removable hollow frame 25 is installed between the free ends of the safety rods 13 and the guard 16. It is configured so that it can be swiveled and fixed in a facing position, and the removable holo-type cabin 26 can be installed by using the safety guard 16 and both safety rods 13, 13 as supports when necessary, such as during rainy weather. We are in a position to do so.

The cabin 26 has a door 27 with a zipper (not shown).
It is provided so that it can be opened/closed and locked by a hook 28, and the passageway 12 for getting on and off can be closed by using the safety rod 13 instead.

The present invention can also be applied to various work vehicles such as agricultural tractors in addition to transport vehicles.

In summary, the present invention is such that the safety rod 13 can be swung and fixed in a state where it projects upward from the vehicle body in the driving section structure of the work vehicle described above, and the holo-type cabin can be fixed. 26, the installation structure of the cabin 26 can be simplified, and the structure is simple enough to be used as a support for the safety rod 13. Since only modification is required, the cabin 26 can be installed at low cost as a whole, making it possible to reduce costs.
