Introduction
This document was developed to study the minimization of the effects of seed coating dust during planting in planters equipped with pneumatic systems:
method: This coating dust may emit dust during the seeding process of the pneumatic system of the planter:
agricultural machinery planter
Reduce the environmental impact of the exhaust air of the pneumatic system fans
1 Scope
This document specifies methods for reducing the environmental impact of exhaust air from pneumatic seeding systems used for sowing coated seeds:
This document applies to pneumatic seeding systems where the "dust" in the seed coating is mixed with the intake air of the fan and discharged into the atmosphere:
This document does not apply to:
--- the gas delivery system between the central gas storage tank and the remote instrument;
---The instrument is located in the central gas storage tank and the gas is discharged through the ground opening device:
This document does not apply to pneumatic equipment for seeding produced prior to publication:
Note: Applicable to countries or regions with stricter environmental protection requirements:
2 Normative references
There are no normative references in this document:
3 Terms and Definitions
The following terms and definitions apply to this document:
3:1
direct drift (discharge) directdrift
The mass of the plant protection product that is expelled and deposited within a defined distance of the sowing area by the action of the air flow during the sowing process:
3:2
fanexhaustzone
Cylindrical boundary (static) used to define the exhaust of a pneumatic system fan:
3:3
Pneumatic (vacuum) seeding system vacuum-stylesowingsystem
Pneumatic system for metering seeds on planters using negative air pressure:
3:4
Zero distance zeroposition
The distance from the sowing area (the sowing area with half the row width from the last row):
NOTE: See Figure 2:
4 Requirements
4:1 General
Use any one of the methods in 4:2 and 4:3 to reduce the environmental impact of the exhaust air of the pneumatic system fan:
One approach is to apply design principles to reduce the effect of fan exhaust, or experimental methods can be used to verify consistency:
