Abstract

The present invention relates to an intermediate storage vehicle, particularly a construction vehicle, having an intermediate storage tank for receiving bulk material, particularly milled material, and a first material delivery conveyor device for delivery, unloading or transfer of the bulk material, the first material delivery conveyor device including a material delivery point, via which the bulk material can be thrown off. The present invention further relates to a milling train having such an intermediate storage vehicle and to a method for milling a road surface.

First claim

What is claimed is:

1. A milling train, comprising:
a road milling machine having a milling device and a milled material loading device;
an intermediate storage vehicle having different sides, comprising:
an intermediate storage tank for receiving milled material;
a first material delivery conveyor device for delivering, unloading or transferring the milled material, the first material delivery conveyor device including a material delivery point via which the milled material can be thrown off; and
a second material delivery conveyor device for delivering, unloading or transferring the bulk material is provided which includes a material delivery point via which the milled material can be thrown off,
the first and second material delivery conveyor devices allowing for delivery, unloading or transfer on two different sides of the intermediate storage vehicle, and
one or more transport vehicles,
wherein the milled material loading device of the road milling machine is designed to load milled material into the intermediate storage tank of the intermediate storage vehicle and the first and the second material delivery conveyor devices are designed to transfer the milled material onto the one or more transport vehicles in a way that enables a work process of the road milling machine to be continuous by compensating for replacement times of said one or more transport vehicles.

2. The milling train according to claim 1 ,
wherein a control unit is provided which controls operation of the first and second material delivery conveyor devices.

3. The milling train according to claim 2 ,
wherein the control unit is designed to independently control or regulate a conveying speed of the first material delivery conveyor device and a conveying speed of the second material delivery conveyor device.

4. The milling train according to claim 1 ,
wherein the first material delivery conveyor device is arranged on the intermediate storage vehicle in such a way that it enables delivery, unloading or transfer of the bulk material in a forward direction of the intermediate storage vehicle to the front, rear, right or left, and that the second material delivery conveyor device is arranged on the intermediate storage vehicle in such a way that it enables delivery, unloading or transfer of the bulk material in the forward direction of the intermediate storage vehicle to the front, rear, right or left, and further wherein the sides of the first and second material delivery conveyor devices on which the bulk material is delivered, unloaded, or transferred, are different from each other.

5. The milling train according to claim 1 ,
wherein the first material delivery conveyor device and the second material delivery conveyor device are essentially structurally identical.

6. The milling train according to claim 1 ,
wherein the first material delivery conveyor device and the second material delivery conveyor device are respectively designed as belt conveyors.

7. The milling train according to claim 1 ,
wherein the first and second material delivery conveyor devices are designed for unloading the same intermediate storage tank.

8. The milling train according to claim 1 ,
wherein the first material delivery conveyor device and/or the second material delivery conveyor device are mounted such that the first material delivery conveyor device and/or the second material delivery conveyor device is rotatable about an axis.

9. The milling train according to claim 1 ,
wherein the respective material delivery points of the first material delivery conveyor device and/or the second material delivery conveyor device are designed to be height adjustable.

10. The milling train according to claim 1 ,
wherein the first and second material delivery conveyor devices are detachable from the intermediate storage vehicle, and the intermediate storage vehicle comprises at least three bearing points arranged on different sides of the intermediate storage vehicle for the first and second material delivery conveyor devices.

11. The milling train according to claim 1 ,
wherein a material switch is provided through which the bulk material can be fed to the first and/or the second material delivery conveyor device.

12. The milling train according to claim 11 ,
wherein a central material feeding device is provided which is controlled via the material switch and can feed the bulk material from the intermediate storage tank to the first and second material delivery conveyor devices.

13. The milling train according to claim 1 ,
wherein the first material delivery conveyor device and the second material delivery conveyor device are independently operated.

14. A method for milling a road surface using a milling train comprising a milling train according to claim 1 , comprising the steps of:
a) milling a surface at a milling depth with the road milling machine;
b) gathering and loading the milled material via the road milling machine into the intermediate storage vehicle having an intermediate storage tank; and
c) independently of step b), transferring the milled material located in the intermediate storage device via the first material delivery conveyor device and/or the second material delivery conveyor device to a first and/or a second transport vehicle.
