Microwave seed sensor for field seed planter - has appts. to detect flow of seed and give indication to operator with control of facility for magnetically treating seeds

摘要

The seed planting apparatus comprises a mobile planting machine to be connected to a tractor or similar vehicle, and having a seed hopper for containing a supply of seeds to be planted. A seed outlet on the hopper feeds a seed dispensing apparatus for delivering seeds to be planted to the ground. A microwave seed sensing apparatus is disposed in the path of travel for seeds discharged from the hopper for detecting the seeds and producing an observable indication to the operator of the presence of seeds in the path of travel. The seed planting apparatus may also include magnetic seed treatment apparatus. The microwave sensing apparatus may be connected in a control circuit for actuating the magnetic field in response to the presence of seeds and for producing an indication to an operator of the passage of seeds.
