Let us look at the process of using the agricultural aerial platform according to the present invention configured as described above.

In the agricultural aerial work platform of the present invention, first, as shown in Figures 1 and 2, the operator rides on the answer plate 40 is located in the lowest state folded X-shaped link 30 on the second bogie frame 22 When the actuator 16 of the track frame 10 is operated by manipulating the controller 45 at the tip of the answer plate 40, the track 16 is moved by the actuator 16 to the work position to be worked. Then stop. At this time, the rotary arm 52 connected by the third cylinder 56 in the track frame 10 is rotated to the upper state, that is, the support 54 of the end of the rotary arm 52 is the track frame 10 Infinite orbit (12) of the outside should be upright.

After moving the aerial platform of the present invention to the working position as described above to operate the two third cylinders 56 by operating the controller 45 on the answer plate 40, if the ground of the working position is flat as shown in FIG. When the piston rod of the third cylinder 56 is extended at the same time, the rotary arm 52 connected through the frame hinge 51 on the track frame 10 side is rotated downward.

When the rotary arm 52 is rotated downward in this way, the support 54 at the end of the rotary arm 52 is also rotated together with the rotary arm 52. At this time, the support 54 at the end of the rotary arm 52 is connected to the ground of the work paper. Press it down until it is stable. When the rotary arm 52 is rotated in this way, the support 54 at the end thereof is wider than the width of the aerial platform, that is, it is supported by the outer track 12 of the track frame 10 so that the platform is more stable. The structure can be secured.

As described above, the supporter 54 at the end of the rotating arm 52 extending from the track frame 10 is rotated downward to support the ground of the work paper, thereby operating the controller 45 to be installed on the X-shaped link 30. The piston rod of the lift cylinder 32 is operated to extend.

When the piston rod of the lift cylinder 32 is extended in this way, the X-shaped link 30 is opened as shown in FIG. 3, and thus the answer plate 40 connected to the upper end of the X-shaped link 30 is up to a predetermined height. Will rise. At this time, the upper and lower ends of the X-shaped link 30 is retracted, the lower end of the second bogie frame 22, the upper end of the answer plate 40 is connected by a hinge of the X-shaped link 30, respectively The upper and lower ends are retracted while being guided along the guide rails of the plate 40 and the second bogie frame 22.

The operator boarded on the answer board 40 in the state in which the answer board 40 is raised to a predetermined height may perform a predetermined height operation. At this time, the worker working on the answer board 40, the support 54 is disposed on both sides of the endless track 12 of the track frame 10 to support the aerial platform in a stable structure, comfortably without any anxiety You can do it.

When the work sheet to be worked using the aerial platform of the present invention is inclined back and forth with respect to the longitudinal direction of the track frame 10, the second cylinder 27 as shown in FIG. 7 when the front of the aerial platform is higher than the rear. When the piston rod is extended so that the piston rod is extended, the upper end of the first bogie frame 21 is rotated to the top with the second bogie frame 22 and the rear end thereof is increased, thereby causing the answer plate 40. Can be leveled. On the contrary, when the front of the aerial platform is lower than the rear side, the second cylinder 27 is operated so that the piston rod is shortened so that the piston rod is shortened and rotated downward about the front hinge 23 of the first bogie frame 21. The rear end is lowered so that the answer plate 40 can be aligned horizontally.

After completing the aerial work as described above, to move the aerial platform to the nearby aerial work site to operate the third cylinder 56 on the track frame 10 side by operating the controller 45 at the tip of the answer plate (40) When the piston rod of the three cylinders 56 is shortened, the support 54 with the rotary arm 52 is rotated upward and lifted up, and then the actuator 16 is operated to operate the endless track of the orbital frame 10. By interlocking (12), the aerial platform can be moved to a nearby aerial platform.

In other words, the first and second bogie frames 21 and 22 are operated to lift only the rotary arm 52 and the support 54 in a state where the plate 40 is horizontally compensated and structurally stable, and then easily moved. You can move to the work place.

In addition, when the work sheet to which the aerial work is to be inclined in the left-right direction, which is the left-right (width) direction of the track frame 10, the second cylinder 27 of the lower side is operated by operating the controller 45 on the answer plate 40. When the piston rod of the second cylinder 27 is extended as shown in FIG. 8, the second bogie frame 22 is centered on the central hinge 26 of the first and second bogie frames 21 and 22. It is rotated to be raised so that the lower side of the second bogie frame 22 is rotated upward and stopped when compensated horizontally.

As such, when the second bogie frame 22 is horizontally compensated, the operator who rides on the answer plate 40 also becomes horizontal, and afterwards, as in the case of flat land, two third cylinders 56 are operated by operating the controller 45 on the answer plate 40. ) To extend the piston rod of the third cylinder 56 to rotate the rotary arm 52 connected to the track frame 10 through the frame hinge 51 is rotated to the lower support of the end of the rotary arm 52 Operate until (54) touches and supports the ground at the work position.

At this time, since the support 54 supports the structurally stable position, that is, wide width, on the outer side of the endless track 12 on both sides of the track frame 10, the bogie frame 20 and the answer plate 40 are stably without shaking. I can support it.

Agricultural aerial platform according to the present invention, even if the work site is inclined in the left and right direction, the left and right (width) direction of the track frame 10, both the endless track 12 and the support 54 on both sides of the ground to ensure a stable and stable support. It can be designed to stably support the balance frame 20 and the counter plate 40 which are horizontally compensated for the inclination in the left and right directions without shaking, and consequently can secure the safety of the counter plate 40 of the aerial platform. The worker can work comfortably without any anxiety.

And the agricultural aerial work platform of the present invention, when the work site to perform the aerial work is inclined in combination with the longitudinal direction of the longitudinal direction of the track frame 10 and the left and right directions of the left and right (width) direction, as shown in FIG. The first and second bogie frames 21 and 22 are operated by operating the first and second cylinders 25 and 27, but are finally mounted through the second bogie frame 22 and the X-shaped link 30 thereon. The plate 40 may be compensated horizontally.

Thus, when the plate 40 is compensated horizontally, since the work sheet is equal to the horizontal, the overall shape of the aerial platform is structurally stabilized, whereby the worker on the plate 40 can perform the aerial work in a comfortable state without anxiety. will be.
