DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile canopy for a road paving vehicle such as an asphalt finisher.
That is, it relates to the structure of the canopy.

[0002]

2. Description of the Related Art In road paving vehicles such as asphalt finishers (hereinafter simply referred to as vehicles), vehicle operations can be roughly classified into (1) vehicle running / receiving and discharging of asphalt mixed material (hereinafter referred to as "mixed material"); ) The operation of the mixing material leveling device (paving width, thickness, compaction degree, temperature) operation. The operation of (1) is performed by an operator in the driver's seat of the vehicle, and the operation of (2) is performed by a thicknessman in a scroll section (leveling device). Focusing on the problem of such operation,
The inventor of the present invention has previously made it possible to move the control device in the driver's seat to the scroll portion via a link mechanism, and to perform both the operations (1) and (2) with one control device. Can be operated by one worker, that is, one-man operation,
Controller to enable improved and labor saving of workability economy - provided the Le device (JP-A 9-11910 No. 9).

[0003] In such a one-man operated vehicle, the main focus is placed on the operator in the driver's seat of the vehicle, so that there is no operator canopy when the vehicle is operated on the screen. Some vehicles, such as mini asphalt finishers, which are operated exclusively for the screw part, have an operator canopy only for the screw part, but both the vehicle driver's seat and the screw part are used. At present, there is no configuration in which one canopy is used while being movable.

[0004]

SUMMARY OF THE INVENTION In a one-man operation canopy, one canopy can be shared for both operation of a driver's seat of a vehicle and operation of a screw section, thereby protecting an operator from insolation and rainfall. The task is to be able to do so.

[0005]

SUMMARY OF THE INVENTION In a road paved vehicle such as an asphalt finisher that can be operated by one person, one canopy-3 is rotated by rotating a canopy-3 mounted on a vehicle body using a link mechanism. The driver seat A and the screw operation unit B can be shared. The link mechanism has two links 4 and 5 having one ends connected to the bracket 2 side behind the vehicle driver's seat A by pins 6 and 8 and the other ends connected to the canopy-3 side by pins 7 and 9 respectively. The vehicle can be moved in parallel to the positions of the driver's seat A and the screw operation unit B. The position of the canopy 3 moved to the vehicle driver's seat A and the screw operation unit B is fixed by a turn buckle 10 attached between the two links 4 and 5. At the lower part of the pin connecting portion of the two links constituting the link mechanism to the bracket 2, a bent-shaped extension is provided, and another pin insertion hole is provided at its lower end, and a canopy corresponding to this pin hole is provided. 3, a pin hole for holding the horizontal position is also provided in the bracket 2, the pins 13 and 14 are inserted, and the canopy moved to the vehicle driver's seat A portion and the screw operation portion B.
The position of No. 3 was fixed. Two links 4 and 5
A spring 12 for assisting operation and cushioning was mounted therebetween. 2
A cylinder for assisting operation and cushioning was mounted between the links 4 and 5 of the book.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. A in FIG.
Denotes a vehicle driver's seat, and B denotes a screw operation operation unit. A bracket 2 is provided at the rear of the handrail 1 near the vehicle driver's seat A.
Is installed. 3 is a canopy. The canopy-3 is attached to the bracket 2 via two links 4 and 5. The ends of the two links 4 and 5 are pivotally connected by pins 6 and 8 on the bracket 2 side and by pins 7 and 9 on the canopy-3 side. Links 4 and 5, upper canopy
3 pins 7 and 9 and lower bracket 2 pins 6 and 8
And a link mechanism, and the canopy 3 is in the driver's seat A of the vehicle.
The screed operating section B is also horizontal on the top.

A turnbuckle 10 for fixing the link mechanism is provided between the links 4 and 5 obliquely. The lower end of the turnbuckle 10 is attached by screwing a screw 11a into a threaded projection 4a fixed to the link 4. The upper end of the turnbuckle 10 is attached by screwing a screw 11b into a threaded projection 4b fixed to the link 5. When the canopy 3 is used at the position of the driver's seat A, the turnbuckle 1
0 is tightened at the a and b positions of the links 4 and 5 (FIG. 1) to fix the position of the canopy 3. Note that 10 in FIG.
Reference numerals a and 10b denote holes provided at ends of the turnbuckle 10, which are larger than the head diameters of the screws 11a and 11b. Numeral 12 is used for assisting operation and cushioning when rotating the canopy 3 with a spring. Of course, it is also possible to use a cylinder instead of the spring 12.

FIG. 2 is a diagram showing the use of the canopy 3 at the position of the screed operation section B. From the state of FIG. 1, the turnbuckle 10 is loosened and removed from the links 4 and 5 to release the link mechanism, and the canopy 3 is rotated above the screed operating section B. Then, the turnbuckle 10 is tightened at the positions A and C of the links 4 and 5 to fix the position of the canopy 3.

FIG. 4 shows an example in which the lower ends of the links 4 'and 5' are bent in a V-shape in place of the turn buckle 10 of FIG. 3, and another pin 13 and 14 can be fixed to this portion. In other words, when changing the operation position from the position shown in FIG. 4 to the position shown in FIG. 5, the pins 13 and 14 are removed in FIG. When the pins 13 and 14 are inserted into the canopy, the link mechanism is also fixed and the canopy
3 is also positioned horizontally.

【The invention's effect】

(1) Using the link mechanism, the vehicle driver's seat A and the screen
In this manner, one set of canopy-3 can be used in two places, a vehicle driver's seat and a screw part, depending on the working style of the day, since the canopy B and canopy-3 can be shared. Can protect workers from insolation and rainfall during pavement work.
This can reduce fatigue of the data. (2) According to the second aspect of the present invention, since only two links 4 and 5 are required for the structure of the link mechanism, the structure is extremely simplified. (3) According to the third and fourth aspects, even when the canopy-3 is moved, the canopy can be easily positioned immediately, so that the operation is facilitated. (4) According to the fifth and sixth aspects, the position can be moved lightly and easily by the action of the spring.
