A discharge port 2 is provided at the bottom of the hopper 1, and a hopper gate 3 is attached to the discharge port 2 so as to be openable and closable. The hopper gate 3 is provided with a motor as a gate drive device 4 for automatically opening and closing the hopper gate 3. The gate drive device is equipped with a first reversible electromagnetic switch (not shown). The hopper 1 is provided on a pedestal 5 composed of four columns. An electric reel 6 is attached to the pedestal 5 near the columns. The electric reel 6 is equipped with a motor (not shown) and a second reversible electromagnetic switch (not shown). Furthermore, electric reel 6
The operation button box 8 connected to the cable 7 is wound up and down freely. The operation button box 8 is provided with an open button 9 and a close button 10 for operating the gate drive device 4 to automatically open and close the hopper gate 3, and further, the motor for winding the cable 7 of the electric reel 6 is wound. A winding button 11 for activating the is provided. Then, upon receiving a radio wave from a transmitter 14 provided in a driver's seat 13 of a truck 12 on a pedestal 5 near the electric reel 6, the motor of the electric reel 6 is operated to hang the operation button box 8. A receiver 15 is provided to enable the operation. FIG. 3 shows a system diagram of the opening / closing control device for the hopper gate. As illustrated, the radio wave of the transmitter 14 is transmitted to the receiver 15. This receiver 15 is connected to a second reversible electromagnetic switch (for unwinding) 17. The close button 10 of the operation button box 8 connected to the cable 7 wound on the electric reel 6 is the first reversible electromagnetic switch (for closing) 16, and the open / close button 9 is the first reversible electromagnetic switch. The first reversible electromagnetic switch 16 is connected to the (open) 16 respectively, and is connected to the gate drive device 4. Further, the winding button 11 of the operation button box 8 is the second

The reversible electromagnetic switch 17 is connected to the motor of the electric reel 6.

Next, the operation of the above embodiment will be described.

First, the driver passes the truck 12 between the columns of the gantry 5 and positions the truck 12 under the hopper 1. Then, the driver turns on the transmitter 14 provided in the driver's seat and transmits a radio wave to the receiver 15 on the gantry 5 from now on. When receiving this radio wave, the receiver 15 causes the motor of the electric reel 6 to rotate in the normal direction, and the operation button box 8 connected to the cable 7 is hung down to a predetermined height. The driver corrects the stop position of the truck 12 using the suspended operation button box 8 as a guide. Since the truck 12 passes between the columns of the gantry 5, there is no displacement in the vehicle width direction. Therefore, track 12
The stop position is such that the operation button box 8 is on the side of the driver's seat 13, and at this time, the mounting position of the electric reel 6 is devised so that the discharge port 2 of the hopper 1 is positioned at the center of the loading platform 18. .

Next, the driver directly operates the operation button box 8 from the driver's seat 13.
First, the open button 9 is pressed to rotate the motor as the gate driving device 4 forward and the hopper gate 3 is automatically opened. When the hopper gate 3 is opened, since the center of the loading platform 18 is located below the discharge port 2, the contents in the hopper 1 are accurately loaded into the loading platform 18.
