Abstract
A sampling system and method are used for extracting a sample of dry product from a receptacle. An extraction tube having a perforated portion is disposed in a product storage volume of the receptacle. A pressurized air source is connected to a first end of the extraction tube. A sample collection device is located outside of the receptacle and serves to separate the sample from an airflow driven by the pressurized air source. An inlet of the sample collection device is connected to a second end of the extraction tube. A sample outlet is adapted to dispense the sample, and an air outlet is provided for venting pressurized air.

A dry product spreader for applying product to a growing crop, the spreader comprising:
- a wheeled frame;
- a first receptacle having a first product storage volume;
- a second receptacle having a second product storage volume;
- a product application system adapted to receive a first product stored in the first receptacle and a second product stored in the second receptacle, and dispense the first product and the second product onto a growing crop;
- a first metering device located under the first receptacle and operable to meter the first product from the first receptacle for delivery to the product application system;
- a second metering device located under the second receptacle and operable to meter the second product from the second receptacle for delivery to the product application system;
- and
- a product sampling system configured to extract a first sample of the first product from the first receptacle or a second sample of the second product from the second receptacle, the sampling system comprising:
- a first extraction tube having a perforated portion that is disposed in the first product storage volume above the first metering device;
- a first pressurized air source connected to a first end of the first extraction tube;
- and
- a first sample collection device disposed outside of the first receptacle and the second receptacle, and having a first inlet connected to a second end of the first extraction tube, a first sample outlet adapted to dispense the first sample, and a first air outlet for venting pressurized air;
- a second extraction tube having a perforated interior portion that is disposed in the second product storage volume above the second metering device and a non-perforated interior portion that is disposed in the first product storage volume;
- a second pressurized air source connected to a first end of the second extraction tube;
- and
- a second sample collection device disposed outside of the first receptacle and the second receptacle, and having a second inlet connected to a second end of the second extraction tube, a second sample outlet adapted to dispense the second sample extracted from the second receptacle, and a second air outlet for venting pressurized air.
