The invention relates to a device (101) for distributing bulk material, in particular seed, on agricultural usable surfaces, comprising a bulk material source (23), a flow path (10) connected to the bulk material source (23), the flow path (10) comprising at least one A conduit for conveying the bulk material from the bulk material source (23) in the direction of the useful surface, and a device for blockage detection (15) in the at least one, several or all lines of the flow path (10). The invention proposes that the device for blocking detection (15) comprises at least one sensor (21 a-d), which is mounted on the outside at the line and is equipped with the sensor (21 a-d), which is equipped with the sensor (21 a-d), as well as an evaluation unit (17) connected to it, depending on the detected mechanical vibration. In addition, the invention relates to a method for distributing bulk material, in particular seeds, on agricultural areas. The invention proposes the following steps: Provision of bulk material, conveying the bulk material through a flow path (10) in the direction of the usable area, wherein the bulk material is supported by at least one sensor of the flow path (21 a-d), detecting a mechanical vibration of the line, and detecting a blockage depending on the detected mechanical vibration.
An eccentric screw pump, comprising a rotor (70) that extends along a longitudinal axis (1) of the rotor from a drive end to a free end, a stator housing (90) with an internal cavity that extends along the longitudinal axis (1) from a stator inlet opening (90a) to a stator outlet opening (90b) and that is designed to accommodate the rotor (70), a drive motor (60) with a drive shaft that is coupled with the rotor (70) to transmit a torque, a first cardan joint (22) which is placed within the transmission of the torque between the drive shaft and the rotor, and a stator outlet flange (100) that is arranged in flow direction behind the rotor (70). The stator outlet flange (100) comprises a flange connection plane (100') that is oriented non- vertically to the longitudinal axis.

APPARATUS FOR DISTRIBUTING A MIXED FLUID AND APPARATUS FOR DISTRIBUTING BULK MATERIAL
Apparatus for distributing a mixed fluid on agricultural productive surfaces. Conduits define flow paths, and sensors are introduced into respective ones of the flow paths, extend in a downstream direction along the flow path and output a measurement signal dependent on a delivery flow measured by the sensor tip. At least one clip is fitted around one of the conduits and has a projection extending into the respective flow path through a corresponding opening in the conduits; the clip has an insertion portion for receiving one of the sensors and a passage means extending as far as the projection, or the projection is a thermally conductive measurement cap. The sensors measure the delivery flow, and an electronic evaluation unit compares the signals output by each one of the plurality of sensors to determine if one or more of the flow paths are blocked.
