Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 shows the working vehicle of this invention. FIG. 2 is a partial longitudinal sectional side view showing one embodiment of the driver's cab of the same, and FIG. 2 is a perspective view of the main parts of the same. 1 in the figure is the driver's cab, but this can also be installed on the top of the work vehicle 2, etc. as shown in Figure 3. Therefore, the front 3 including the glass window, the rear 4, the left side 5, and the right side (in Figure 3 (not shown) were vertical surfaces.

[0011] Then, the four circumferential surfaces of the driver's cab 1 are horizontally divided into two at approximately 1/2 of the height. However, it is a combination of an upper divided box body 8 including a roof plate 7 and a lower divided box body 9. this Of these, the lower divided box body 9 is fixed to the work vehicle 2, and the upper divided box body 8 is the lower divided box body 9. Expand the diameter of the box body 9 and move its lower end vertically relative to the upper end of the lower divided box body 9 Fit freely. Further, a weight is applied to the mutually fitting ends of the upper divided box body 8 and the lower divided box body 9. Form the horizontal flanges 16, 17 in the direction of mating, and attach one of the flanges to the I installed the packing 18 that absorbs.

0012 These horizontal flanges 16, 17 are in a “nested” state with respect to the lower divided box body 9. The horizontal flange 16 of the lower divided box body 9 plays the role of preventing the partially divided box body 8 from coming off. A through hole 19 is provided in the horizontal flange 17 of the upper split box body 8, and a bulge protruding through the through hole 19 is provided in the horizontal flange 17 of the upper split box body 8. A pin 20 with a large head is provided, and a pin 20 with a large head is provided on the horizontal flange 16 near the through hole 19. Turn the lock piece 21 which has a notch 21a that fits directly under the large head of the protruding pin 20. Installed so that it can move freely. These through hole 19, pin 20, and lock piece 21 create a wedge action. A fastener is constructed that locks and secures the horizontal flanges 16 and 17 in an overlapping state using the kanunuki effect. It is something that can be achieved.

[0013] In addition, on the front 3 side, the lower side usually separates the driver's seat 10 and the engine compartment 11 of the vehicle. Since there is a partition wall and an instrument panel, the front lower part of the driver's cab 1 is either very small or not at all. It becomes a structure without any structure. In addition, the upper side of the front panel 3 is a large window glass called the front panel 12. However, this is blocked by the partition wall and instrument panel and cannot be lowered, so Flip-up method using a hinge or guide inside the upper split box body 8 as shown in Figure 6 A rail 13 is provided, and the guide rail 13 slides under the roof board 7. It can be moved to the side, that is, under the ceiling, and is held by the roof board 7 so that it can be lowered or raised. did.

[0014] In addition, the roof at the part where the lower edge of the front glass 12 touches and directly above this. A watertight member 14, 15 made of a rubber plate or the like is placed on the underside of the base plate 7, covering the entire width of the front glass 12. Attach the corresponding lengths, and when the upper split box body 8 is lowered, the upper and lower watertight members 14, 15 so that they meet and form a watertight structure.

[0015] Entrance/exit doors 22 are provided at two locations on the left and right, or one location only on one side. This door 22 also has four circumferences. Divide into upper and lower parts at the same height as the surface member, and separate the upper and lower parts with independent hinges. Attach it to the box so that it can be opened and closed. and outside the lower half of door 22 in the closed state. The surface is the same as the outer surface of the lower divided box 9, and the inner surface of the upper half is the same as the inner surface of the upper divided box 8. If it is on the same surface as the top and bottom, and the top and bottom are both closed, the upper split box body 8 can be moved up and down freely. The structure will allow for

[0016] Although the vertical movement of the upper divided box body 8 can be performed manually, A cylinder for lifting and lowering the upper split box body 8 is interposed between the split box body 8 and the lower split box body 9. Instead of directly moving the upper divided box body 8 up and down by hand, it can be easily moved through the cylinder. It can be raised and lowered. In the illustrated embodiment, the cylinder is a hydraulic cylinder. As shown in Figure 5, inside the operator's cab 1, there are A hydraulic power source device 24 is provided with a plurality of hydraulic cylinders 23 connected to the It is installed at an appropriate position on the vehicle outside the driver's cabin 1. This hydraulic power source equipment has 25 oil tanks, manual Alternatively, it consists of an electric hydraulic pump 26 and a switching valve 27. In addition to hydraulic pressure, the cylinder Air cylinders, etc. can also be used.

[0017] Although not shown, the upper split box body 8 should be placed near the ceiling and below at an appropriate position on the plane. The vicinity of the upper end of the partially divided box body 9 is connected with a wire bundle. This wire bundle is passed through the upper split box body 8 downward. When lowered, it becomes a coil itself or is wound up on a reel. If it hangs down carelessly, gets caught between the boxes 8 and 9, or rises again, something may It is designed so that it will not get caught. This wire bundle has an upper split box Sends power and signals to indoor lights, wipers, fans, speakers, communication devices, etc. attached to 8. It is for.

[0018] Next, usage and operation will be explained. Load the work vehicle 2 etc. onto the transport vehicle. After that, stop the engine, turn off the main switch, and move the front glass 12 to the guide rail 13. Push it up to the ceiling along the

[0019] The driver removes the lock piece 21 from the pin 20, steps out of the driver's cab 1, and closes the door 22. So After that, if the hydraulic cylinder 23 is contracted by operating the hydraulic power source device 24, the lower divided box body 9 is On the other hand, the upper divided box body 8 moves downward, and this upper divided box body 8 moves to the lower divided box body 9. They overlap on the outside, and the height of the driver's cab 1 becomes low as shown in FIG.

[0020] In addition, when in use, perform the reverse operation on the transport vehicle to separate the upper part from the lower divided box body 9. The split box body 8 is moved upward, and the horizontal flanges 16 and 17 are overlapped with each other. horizontal hula The large head of the pin 20 of the horizontal flange 16 protrudes from the through hole 19 of the screw 17, so this pin If the lock piece 21 is fitted to the ring 20, the horizontal flan 16 and 17 are locked and fixed together in a superposed state, and the packing 18 is interposed between them, so Watertightness can be ensured. In this way, the upper divided box body 8 is attached to the upper part of the lower divided box body 9. As shown in FIG. 3, a driver's cab 1 of a normal height can be formed.

[0021] Note that the front glass is closed only while the upper split box body 8 is being raised or lowered. The front glass 12 will be opened, but after it has finished rising and the front glass 12 has been returned to its normal position, or After the has finished descending, it is completely watertight with the watertight members 14 and 15, so there is nothing inside the operator's cab 1. There is no need to worry about rain, wind, flooding, or theft.

[0022] Furthermore, the chair 28 of the driver's seat 10 and the steering wheel 29 are lowered. If there is a risk of getting in the way of the partially split box body 8, place the backrest of this chair 28 in front of you. The steering wheel (steering wheel) 29 can be used as a tilt handle. That's fine.
