し込み排出を行うことができる。 Next, the operation of the present invention will be explained. First, when discharging to a high place such as a silo, the hydraulic pumps 34 and 35 are driven as appropriate, and then the third control valve 3
2 to the left position, the telescopic cylinder 10 is extended, and the second conveying cylinder 8 is erected.Meanwhile, the first conveying cylinder 7 is appropriately rotated together with the second conveying cylinder 8 by a rotating means (not shown). The carry-out port 13 is made to face the input port of the silo 15. Thereafter, when the control lever 21 is pulled forward from the neutral position (position in FIG. 4), the second shaft 23 rotates and pulls the second control valve 28 via the bell crank 23'.
Therefore, the second control valve 28 is switched to the left position to supply pressure oil to the hydraulic motors 31 and 30 in this order, thereby driving the screws 12 and 11 in forward rotation. Next, tilt the control lever 21 to the right (position in Figure 4)
The first shaft 22 is pulled to the left, and along with this movement, the first control valve 27 is also pulled to the left. Therefore, while the second control valve 28 remains switched, the first control valve 28 remains switched.
The control valve 27 is switched to the left position to supply pressure oil to the hydraulic motor 29 and drive the screw 6 in forward rotation. The rotation of the screws 6, 11, and 12 allows the powder and granular material to be transported from the tank 2 through the first transport cylinder 7 and the second transport cylinder 8 to the silo. When the discharge operation is completed, the control lever 21 is returned to the neutral position, and the second conveying cylinder 8 is operated in the opposite manner to the above to be stored in the traveling position. On the other hand, when discharging to underground equipment, remove the pin (not shown) from the lever 19 in FIG. 2, rotate it counterclockwise, and align the pin hole 19 1 with the pin hole 20 2 of the bracket 20. When the damper 18 is fixed in the open position, the damper 18 is fixed in the open position as shown by the chain line in FIG. In this state, when the control lever 21 is tilted to the right from the neutral position (position in Fig. 4), the first control valve 27
The motor only switches to the left position and the pressure oil is transferred to the hydraulic motor 2.
9, and the screw 6 is driven to rotate in the forward direction. Therefore, the granular material can be dropped from the inside of the tank 2 through the connecting tube 5' and the discharge port 17 into underground facilities, etc., and discharged therefrom.

なうことができる。 As described above, the present invention allows the powder and granular material in the storage tank to be discharged to a high place such as a silo by closing the discharge port and rotating all the screws in sequence, or by opening the discharge port. By rotating only the screw placed at the bottom of the storage tank, it is possible to selectively discharge to the bottom such as underground facilities, and with a single powder transport vehicle, efficiency can be adjusted according to the discharge location. It is possible to carry out good discharge work.
