Load the earth and sand on the bed in the state of the reduced set, and do the work of wholesale the earth and sand on the bed. Then, after loading the earth and sand on the loading platform, when the above-mentioned operating shaft is rotated by electric or manual operation, the operating roller of the operating arm on the seat portion moves up along the guide rail on the vehicle body side to expand the seat portion. It is set in a state, overlaid with earth and sand on the loading platform. When unloading earth and sand, when the operating axis is reversed, the operation roller of the sheet moves down the guide rail, and the sheet is restored to the original reduced set state, and the "loading and unloading of soil" is performed. Each time "", the reduced set and the expanded and expanded cover are repeated.

The ascending operation is performed, and the seat portion is opened and deployed so as to sequentially cover the upper portion of the loading platform. Thus, when the operating roller reaches the top dead center of the guide rail, the pair of seats, which have been opened and moved from the left and right side plates of the loading platform, are in the expanded position, covering the upper side of the loading platform from the left and right, and the sediment loaded on the loading platform. Can be set. And
When the operation shaft is reversed, the operation roller and the sheet unit operate in the reverse direction of the trajectory, and when the operation roller reaches the bottom dead center of the guide rail, the sheet unit is restored to the reduced set position of the two-fold overlapping. it can.

Is unnecessary, and the work is particularly efficiently performed, and the quality of the sheet cover set is stabilized. In a state where the seat portion is suspended from the loading side plate, the operating roller of the operating arm of the outer frame of the seat portion is locked at the bottom dead point of the guide rail, and the outer frame is suspended. Therefore, the outer frame and the inner frame of the sheet portion in the folded and reduced posture are not unnecessarily opened.

As shown in FIG. 1, a pair of seat portions 6 suspended from side plates 3A and 3B as shown in FIG.
6 and is temporarily locked, and is held in a reduced set position in which the inner frame 4 and the outer frame 5 are folded and overlapped. Then, in this state, the sediment is loaded on the loading platform 2 or the loaded sediment is discharged by tilting the loading platform 2 backward.

順次大にして荷台２の上方空間に拡大伸長していく。When earth and sand are loaded on the loading platform 2, the rotating shaft 10 is automatically rotated to rotate the inner frame 4 around the rotating shaft 10. When the inner frame 4 is rotated around the rotating shaft 10, the inner frame 4 The side plates 3A, 3 while the outer frame 5 is open to each other
B, the operating roller 14 of the operating arm 13 of the outer frame 5 simultaneously rises out of the bottom dead center pocket 16 and rises the guide rail 15 by the rotation force at the same time as the outer frame 5 inclines. The outer frame 5 expands and expands into the space above the carrier 2 with the mutual opening gradually increased.

い。The loading sheet device of the embodiment described above is a storage set which is suspended from the side plates 3A and 3B by the reduced setting of the sheet portion 6, and is expanded from the storage set state to hold down the earth and sand 20 of the loading platform 2 and to cover it. Since the unfolding expansion set can be mechanically operated by one-touch operation, the work of attaching and detaching the sheet by the conventional manual operation becomes unnecessary, so that the workability is particularly improved, and the sheet cover is mechanical. The quality of the sediment presser is stable without variation. Note that the sheet portion 6 in the reduced set state includes the outer frame 5
The operation roller 14 of the operation arm 13 of the guide rail 1
Since the outer frame 5 is locked and held by being engaged with the bottom dead center pocket 16, there is no possibility that the seat portion 6 will open or hang down even when the dump truck 1 travels in the reduced set state.
