A conveyor belt scale (1) for transporting and weighing bulk material, having a rocker (6) that acts on a rod system (9), and having a weighing cell (11) connected with the rod system (9), is supposed to be configured in such a manner that the weighing cell, in particular, can also be reached from the outside. This is achieved in that the conveyor belt (2) is surrounded by a pressure-resistant, explosion-protected housing (7), whereby the rod system (9) that acts on the weighing cell (11) is passed out of the housing (7) by way of at least one elastic bearing (10) having a pressure-resistant seal, whereby the weighing cell (11) is positioned outside of the housing (7).

1. A conveyor belt scale for transporting and weighing bulk material, having a rocker that acts on a rod system comprising a transfer rod for transferring rocker movements, and having a weighing cell connected with the rod system, wherein the conveyor belt is surrounded by a pressure-resistant, explosion-protected housing, wherein the rod system that acts on the weighing cell is passed out of the housing by way of at least one elastic bearing having a pressure-resistant seal, wherein the weighing cell is positioned outside of the housing, wherein the transfer rod for transferring the rocker movements is equipped with a separation coupling, and wherein the housing is provided with a viewing window for monitoring the coupling process. 2. The conveyor belt scale according to claim 1, wherein the housing is configured to be cylindrical, at least in the region of the weighing cell, wherein the rod that acts on the weighing cell passes through the housing tangentially and is guided in two elastic sealing bearings. 3. The conveyor belt scale according to claim 1, wherein the housing is provided, in the region of the weighing cell, with an attachment that projects outward and has at least two parallel side walls that lie opposite one another, in which a diaphragm through which the rod system that acts on the weighing cell passes is positioned, as a pressure-resistant seal. 4. The conveyor belt scale according to claim 1, wherein the rocker has an attachment through which the transfer rod passes, wherein the transfer rod is provided with an outside thread in the region of the attachment, and the attachment is provided with a corresponding inside thread, for adjusting the transfer rod. 5. The conveyor belt scale according to claim 1, wherein the frame that carries the conveyor belt is equipped with wheels that can run on rails, for bringing the conveyor belt with the related scale elements into the pressure-resistant, explosion-protected housing and/or removing it from it. 6. The conveyor belt scale according to claim 1, wherein the drive roller of the conveyor belt is equipped with a coupling element, and the drive motor is equipped with a corresponding coupling element, for tool-free coupling and uncoupling of the drive roller.
