Abstract: A robust low-cost wireless sensor with an internal battery, which permits operation for extended periods without the necessity of maintenance, for monitoring the flow of particulate solid material such as chemical fertilizers, small seeds, granulated foodstuffs, and others.

Abstract: A precision seed-dispensing system of the type applied on planters with a machine element that touches the soil and having a chassis that supports the seed meter. In accordance with the system disclosed herein, it may also have a damper system between the machine element that touches the soil and the seed meter, irrespective of the model or its shape.

Abstract: The present invention patent relates to a solution for avoiding errors during the seed-metering process in planters, and comprises the following six steps: autonomous electricity generation to power the monitoring system; monitoring the seed charge in the metering disk (pre-sensor); monitoring the clogging of the metering disk by seeds (post-sensor); monitoring obstructions in the seed duct (post-sensor); processing the monitoring data; transmitting the processed data wirelessly to the central monitoring unit for follow-up and decision-making by the operator.

Abstract: A metering and mixing system of particulate solids for seed rotary dispenser in agricultural equipment for sowing, where the seed rotary dispenser is of a type comprised by a cylindrical compartment with circular cross-section and low height, which is mounted under a small seed feeder bin; being such seed rotary dispenser driven at the bottom by a miter gear coupled to the planter driving system, which provides rotation to a spinning disc provided with a number of calibrated orifices and with a ring which is mounted facing the disc and which has an passage opening through which the seeds housed in the disc holes fall in a given point of the device, given point of the device, being provided between the seed bin and the rotary dispenser a metering and mixing equipment for particulate solids.
