Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a boom type aerial work vehicle used for harvesting work in an orchard.

[0002]

[Prior art]

 Conventionally, there are various types of boom type aerial work vehicles, which are disclosed in, for example, Japanese Patent Application Laid-Open No. 4-267811 and Japanese Utility Model Application Laid-Open No. 4-107112. Further, in these boom type work vehicles, a work table on which an operator rides and a mounting table on which a container for storing a harvested product is mounted are provided on the tip end side of the boom that is vertically rotatable. In addition, a loading platform for loading containers is provided on the frame of the vehicle body, an empty container is placed on this loading platform at the start of work, and when the containers placed on the loading platform are full of harvested products, the containers are placed. There is also a boom-type aerial work vehicle in which the empty container that has been placed on the loading platform is removed and placed on the loading platform as well as lowering it from the loading platform.

[0003]

[Problems to be solved by the device]

 When the containers on the loading platform are used up, it is necessary to go to the position where there are many containers, for example, the position where the truck loaded with the containers is stopped, to take the containers. Here, since the boom, engine, etc. that are rotated downward are located on the frame, it is not possible to mount a cargo bed with sufficient space on the frame, and a container that can be placed on the cargo bed cannot be mounted. The number is as small as one or two. Therefore, the number of times of picking up containers to the position where there are many containers increases, which hinders the improvement of work efficiency.

Further, when the container on the loading platform is placed on the loading platform, since the space between the loading platform and the work platform is wide, an operator must descend from the work platform and carry the container. No, it takes time.

[0005]

[Means for Solving the Problems]

 According to the present invention, one end of a boom is rotatably connected to a vehicle body in a vertical direction, and a workbench on which a worker rides and a mount on which a container for storing crops are placed are provided on the other end of the boom. In a boom-type aerial work vehicle, a holding mechanism for slidably and detachably holding the plurality of containers on the boom is provided, and the containers held by the holding mechanism are slid to the workbench side. A means of transportation was provided.

[0006]

[Action]

 By picking up the containers held by the holding mechanism one by one, placing them on the placing table, and storing the harvested products in this container, the number of times to go to the position where there are many containers is reduced and the harvesting work is reduced. Can be performed continuously. In addition, since the container held by the holding mechanism is slid to the workbench side by the moving means, the worker must drop the work held by the holding mechanism on the worktable from the workbench. You can do it without getting on the workbench.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. First, FIGS. 1 to 3 show the entire structure of a boom type aerial work vehicle, in which a vehicle body 4 having a front wheel 1 and a rear wheel 2 driven by an engine (not shown) mounted on a frame 3 is mounted. One end side of the boom 5 is connected to the above so as to be vertically rotatable. At the other end of the boom 5 which is positionally movable in the vertical direction, a work table 6 on which an operator rides and a mounting table 8 on which a container 7 for storing harvested crops is mounted are provided. There is.

Here, the boom 5 is formed by a first link 5a and a second link 5b arranged in parallel, and the boom 5 is provided between the frame 3 and the first link 5a. A hydraulic cylinder 9 for rotating in the vertical direction is connected. Further, the workbench 6 is provided with an operation unit (not shown) for driving the front wheel 1 and the rear wheel 2 and for expanding and contracting the hydraulic cylinder 9.

A holding mechanism 10 is attached to both sides of the first link 5a for holding the plurality of containers 7 slidably and detachably along the first link 5a. The holding mechanism 10 includes a support rod 10a which is arranged in parallel with the first link 5a and supports the lower surface of the container 7, and a side surface of the container 7 which is arranged in parallel with the first link 5a. It is formed by the supporting rod 10b which supports.

Next, the holding mechanism 10 is provided with moving means 11 for moving the container 7 held by the holding mechanism 10 toward the workbench 6 side. The moving means 11 has a locking plate 11a locked to the rear end side of the container 7 which is the farthest from the work table 6 among the containers 7 held by the holding mechanism 10, and one end of this locking plate 11a. It is formed by a wire 11b connected to the plate 11a and a spiral spring (not shown) housed in the case 11c and connected to the other end of the wire 11b.

In such a structure, when the boom type aerial work vehicle is used for harvesting fruit trees, the boom type aerial work vehicle is moved to a predetermined working position and then the hydraulic cylinder 9 is used. The boom 5 is rotated upward as shown in FIG. 1 by extending. Here, since the boom 5 is formed by the first link 5a and the second link 6b arranged in parallel, the workbench 6 on which the operator rides and the mounting table 8 on which the container 7 is placed are in a horizontal state. It rises while maintaining it.

The operator who has lifted the workbench 6 harvests the fruit trees and stores the fruit trees in the container 7 placed on the mounting table 8. When the container 7 is full of harvested fruit trees, the hydraulic cylinder 9 is contracted to rotate the boom 5 downward as shown in FIG. 2, and the harvested fruit trees are filled up. Lower container 7 onto the ground. Then, of the containers 7 held by the holding mechanism 10, the container 7 located closest to the work table 6 is taken out and placed on the mounting table 8, and the hydraulic cylinder 9 is extended again to raise the boom 5. .

When the container 7 newly placed on the mounting table 8 is full of fruit trees, the hydraulic cylinder 9 is rotated downward again to lower the container 7 onto the ground, and the holding mechanism 10 is operated. The container 7 held is placed on the placing table 8 again. While repeating the above work, the harvesting work is continued until the containers 7 held by the holding mechanism 10 are exhausted, and when the containers 7 held by the holding mechanism 10 are exhausted, the boom type aerial work vehicle is operated. Is moved to a position where a large number of containers 7 are present, for example, to a position where the truck loaded with the containers 7 is stopped, and the holding mechanism 10 holds a plurality of containers 7.

Here, since there is a sufficient space on both sides of the boom 5, the holding mechanisms 10 provided on both sides of the boom 5 can hold a plurality of containers 7. For this reason, the number of times the container 7 is picked up during the harvesting work is reduced, and the work efficiency of the harvesting work is improved. Further, when the container 7 held by the holding mechanism 10 is taken out and placed on the placing table 8, the remaining containers 7 held by the holding mechanism 10 slide to the work table 6 side by the moving means 11. . Therefore, the operator can carry out the work of placing the container 7 held by the holding mechanism 10 on the worktable 8 without getting off from the worktable 6. Therefore, the work of taking out the container 7 from the holding mechanism 10 and mounting it on the mounting table 8 does not take time and the working efficiency of the harvesting work is further improved.

In the present embodiment, the moving means 11 is formed by the locking plate 11a, the wire 11b, and the spiral spring housed in the case 11c. By moving the boom 5 so that the workbench 6 side is below the horizontal position when it is turned to, the container 7 may be slid to the workbench 6 side by its own weight. .
