However, in the conventional belt feeder, when the clay of the earth mass carried into the hopper has a high viscosity, even if the belt is rotated, the belt is finely crushed by the vibration and passes through the opening of the gate. Often, most of them stuck to the back of the gate and clogged the gate opening. For this reason, no belt feeder has been developed so far that the earth mass can be finely crushed and continuously passed through the opening of the gate, and this operation has had to rely on the human power of a husband and wife. As a result, the construction period is extended and construction costs are increased.

The present invention has been made to solve such a problem. When a soil mass is carried into a hopper of a belt feeder, the soil mass is finely crushed to smoothly pass through an opening of a gate, and a predetermined amount is obtained. It is an object of the present invention to provide a belt feeder capable of conveying a soil amount.

In the tunnel 3, a plurality of belt conveyors 4 are connected to each other in order to transport the earth mass excavated by the backhoe or the like in the excavation section 1 to the shaft 2. The tip of the belt conveyor 4 is connected to a tray lifter 5 installed in the shaft 2, so that the earth mass transferred to the shaft 2 position by the belt conveyor 4 is transferred to the hopper 6 fixed at an arbitrary height above the ground. The hopper 6 guides the hopper 6 to a loading platform such as a dump 7 disposed below the hopper 6. At the position of the excavation section 1 at the rear end of the belt conveyor 4, the following belt feeder 8 that conveys an amount of soil compatible with the transport capacity of the tray lifter 5 is connected. The other belt conveyor 4a for transporting is connected. The earth mass excavated by the backhoe or the like is conveyed to the belt feeder 8 by the belt conveyor 4a, and is fed to the belt feeder 8.
After the soil volume has been adjusted using the method shown in Fig. 8, the material is transported to the ground via each belt conveyor 4 and tray lifter 5 in sequence.

As shown in FIGS. 2 and 3, a belt feeder 8 has a horizontal support shaft 10
The output shaft 11 of the belt drive is rotatably supported, and the inner peripheral surface of the endless belt 12 is joined to the outer periphery of these shafts, so that the endless belt 12 moves integrally with the rotation of these shafts. I have. The lower peripheral surface of the endless belt 12 is
