The invention relates to a device (101) for distributing bulk material, inparticular seed, on agriculturalusable surfaces, comprising a bulk material source (23), a flow path (10)connected to the bulk materialsource (23), the flow path (10) comprising at least one A conduit forconveying the bulk material from thebulk material source (23) in the direction of the useful surface, and a devicefor blockage detection (15) inthe at least one, several or all lines of the flow path (10). The inventionproposes that the device forblocking detection (15) comprises at least one sensor (21 a-d), which ismounted on the outside at theline and is equipped with the sensor (21 a-d), which is equipped with thesensor (21 a-d), as well as anevaluation unit (17) connected to it, depending on the detected mechanicalvibration.In addition, the invention relates to a method for distributing bulk material,in particular seeds, onagricultural areas. The invention proposes the following steps: Provision ofbulk material, conveying thebulk material through a flow path (10) in the direction of the usable area,wherein the bulk material issupported by at least one sensor of the flow path (21 a-d), detecting amechanical vibration of the line,and detecting a blockage depending on the detected mechanical vibration.
