    摘要: A monitoring arrangement comprises units for sensing the flow of seeds through each coulter of a sowing machine and indicating units installed on a part of the machine where the coulters are supported. A common, central unit to indicate an interruption occurring in any coulter is also provided, acting via a common electric conduit that feeds signals from the indicating units to the central unit. The invention suggests one indicating unit for a maximum of three sensing units but preferably the number of the indicating units is half that of the sensing units while the number of the latter is identical with that of the coulters. The arrangement may further include a unit for counting fault locations, connected to the indicating units by the common conduit. At least some of the sensing units may be in the form of piezoelectric sensors that respond to the impingement of the seeds within the coulters. The sensing units are preferably installed within and near the lower ends of the coulters, substantially at soil level when the sowing machine is operated.
