The answer plate 40 may be provided to include a rectangular main answer plate and an auxiliary answer plate which is mounted on one or both sides of the main answer plate in order to secure a wider working space.

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, an operator rides on the answer plate 40 in which the X-shaped link 30 on the bogie frame 20 is folded and positioned in the lowest state, and the controller at the tip of the answer plate 40 ( When the actuator 14 of the track frame 10 is operated by operating 45, the endless track 12 is interlocked by the actuator 14 to move to the work position to be worked and then stops. At this time, since the rotary arm 52 connected by the third cylinder 56 in the track frame 10 is rotated upward, the support 54 of the end of the rotary arm 52 is connected to the track frame 10. The track 12 is in a state standing up outside.

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, as shown in FIG. 7, the rotary arm 52 connected through the frame hinge 51 on the side of the track frame 10 is rotated downward with the same rotation angle.

Since the support 54 at the end of the rotary arm 52 is also rotated with the rotary arm 52 at the same rotation angle as described above, the aerial platform is stably held by pressing the ground of the work paper while the aerial platform is kept flat. At this time, the support 54 is wider than the width of the aerial platform, that is, because it supports the outer track 12 of the endless track 12 of the track frame 10 it is possible to ensure a more stable aerial platform support structure.

As described above, the controller 45 is operated on the X-shaped link 30 by lowering and lowering the support 54 at the end of the rotation arm 52 extending from the track frame 10 to support the ground of the work paper. 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. 1, 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 relatively retracted, the lower end of the bogie frame 20, 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 balance frame 20.

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 24 as shown in FIG. 8A when the front of the aerial platform is higher than the rear. When the piston rod is extended so that the upper and lower bogie frames 21 and 22 are rotated around the top bogie frame 21, the upper bogie frame 21 is relatively rotated and the rear bogie becomes higher. 21 and the answer plate 40 can be aligned horizontally. On the contrary, if the front of the aerial platform is lower than the rear side, the upper and lower bogies can be operated by operating the second cylinder 24 to shorten the piston rod as shown in FIG. 8B. Since the upper bogie frame 21 is relatively rotated by lowering the rear end of the frame 21 and 22 around the front hinge 23, the upper bogie frame 21 and the answer plate 40 can be horizontally aligned. A.

After the horizontal alignment of the work sheet inclined back and forth with respect to the longitudinal direction of the aerial platform, and also by operating the controller 45 on the answer plate 40 to operate the two third cylinders 56 as shown in Figs. 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.

The support 54 at the end of the rotary arm 52 rotated downward is also rotated together with the rotary arm 52 to stably hold the ground of the work paper. At this time, the support 54 is a wider than the width of the aerial platform, that is, because it is sustained in a structurally stable state outside the endless track 12 of the track frame 10 it is possible to secure a more stable aerial platform support structure. .

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 cylinder 56 is shortened, the support 54 with the rotary arm 52 is rotated upward and lifted up, and then the actuator 14 is operated to operate the endless track of the track frame 10 ( By linking 12) the aerial platform can be moved to the nearby aerial work site.

In other words, the upper bogie frame 21 and the answer plate 40 is a horizontally compensated state, in a structurally stable state by lifting only the rotary arm 52 and the support 54 and then can easily move to a nearby work place.

In addition, when the work sheet to be worked using the aerial platform according to the present invention is inclined in the horizontal direction of the track frame 10 in the horizontal direction, the first cylinder of the lower side by operating the controller 45 on the answer plate 40 While operating the 18, extending the piston rod of the first cylinder 18, the lower side of the bogie frame 20 connected by the bracket 15 and the tilting hinge 17 of the track frame 10 is rotated and raised At the same time, the track frame 10 is also rotated and tilted so that the bogie frame 20 is horizontally compensated (see FIGS. 9A and 9B). At this time, the rotary arm 52 and the support 54 connected to the track frame 10 is located on the outer upper portion of the track 12.

When the bogie frame 20 is horizontally compensated as described above, the operator who boards the answer plate 40 also becomes horizontal, so that the overall shape of the aerial platform is structurally stabilized and inclined in the left and right directions with respect to the longitudinal direction of the track frame 10. Even if it is, the endless track 12 of the left and right track frame 10 supports the ground reliably and stably, such as almost flat ground.

Accordingly, when the actuator 14 is operated by operating the controller 45 on the answer plate 40, the track 12 of the track frame 10 interlocked by the actuator 14 is driven to stabilize the aerial platform. It is possible to drive in the forward and backward direction of the aerial platform in the state, and consequently, it is also possible to move the aerial platform to the nearby aerial platform easily and quickly.

After compensating the bogie frame 20 horizontally as described above, the controller 45 on the plate 40 is operated to operate the two third cylinders 56 as in the case of the flat plate, but the piston rod of the third cylinder 56 is operated. The rotating arm 52 connected to the track frame 10 through the frame hinge 51 is rotated downward until the support 54 at the end of the rotating arm 52 touches and supports the ground at the working position. To operate. 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.
