In order to increase the fitness for use of a closing device (1) for continuously and gravimetrically dosing pourable material, particularly rough fuels, a flow of material is conveyed from a charging opening (5) to an emptying opening (7) in a housing (4) with a rotor (3), which is driven about a v
In order to increase the fitness for use of a closing device (1) for continuously and gravimetrically dosing pourable material, particularly rough fuels, a flow of material is conveyed from a charging opening (5) to an emptying opening (7) in a housing (4) with a rotor (3), which is driven about a vertical rotation axis, while determining the instantaneous load over a measuring section, and with a force measuring device (10), which detects the instantaneous load of the flow of material guided via the rotor (3) and which is connected to the housing (4) mounted on a pivot axis (8). According to the invention, a vibrating funnel (50) with a vibration generator (52) is provided above the charging opening (5) of the rotor (3).

1. A dosing device for the continuous, gravimetric dosing of pourable material, particularly rough fuels, the dosing device comprising: a housing having a charging opening, an emptying opening, and a measuring section, the housing being pivotable about a pivot axis, the charging opening and the emptying opening being spaced apart along the pivot axis;a rotor disposed within the housing, the rotor being driven about a vertical rotation axis, the rotor configured to convey a flow of material from the charging opening to the emptying opening;a force measuring device connected to the housing, the force measuring device configured to detect an instantaneous load of the flow of material over the measuring section; anda vibrating funnel with a vibration generator disposed above the charging opening, the vibration generator being disposed in line with and vertically above the pivot axis of the housing. 2. The dosing device of claim 1, further comprising a compensator, wherein the vibrating funnel is suspended from a frame via the compensator so as to be capable of freely swinging in all directions in space. 3. The dosing device of claim 1, further comprising a compensator, wherein the vibrating funnel is connected to the housing via the compensator. 4. The dosing device of claim 1, wherein the vibration generator is configured to swing predominantly in a horizontal plane. 5. The dosing device of claim 1, wherein the vibration generator is configured to be continuously operated. 6. The dosing device of claim 1, wherein the rotor includes a peripheral ring having a slightly smaller diameter than a diameter of the housing so as to form a circumferential gap, the peripheral ring having an upper rim which extends in an outward direction to cover said circumferential gap. 7. The dosing device of claim 6, wherein assistant cams are provided in the circumferential gap, the emptying opening projecting beyond the peripheral gap in a radial direction and communicating with the circumferential gap. 8. The dosing device of claim 1, further comprising a blast nozzle arranged above the emptying opening, the blast nozzle being aligned downward, the blast nozzle configured to be operated with inert gas or hot-air. 9. The dosing device of claim 1, wherein the dosing device is supported on load cells with a framework so as to allow for check weighings. 10. The dosing device of claim 1, wherein the vibrating funnel can be activated in the case of varying instantaneous loads being too small or exceeding settable thresholds. 11. The dosing device of claim 1, wherein the pivot axis extends through the center of the charging opening and the bottom of the emptying opening.
