The paper discusses technical aspects involved in developing seeding control systems for grain seeders and sowing machines. Construction and technological parameters of seeding control systems are based on the analysis of the available machinery. As a result an operation-performing unit was constructed and tested in field trials. The RatinalRose visual simulation environment was used to design the software of the seeding control system. The environment allowed for interpreting the volume concentration of particles. A procedure for collecting and presenting data was developed. COMPAS com106 puter program was used to create a 3D design of the sensor and measure its parameters, then the sensor case was made using a 3D printer. Field trials involved comparing 2 identical drills under identical conditions. The drill equipped with the seeding control system had better indices of time saving and efficiency (by 22 %). The study results allowed us to develop the software for the seeding control system and determine the optimal design and process parameters of the seeding control sensor for a pneumatic drill in order to reduce clogging in the seed pipes and improve the quality of seed distribution.
Presowing seed treatment is the first step in growing crops and obtaining a predicted high-quality yield. It plays a vital role in an integrated plant protection system. When treating seeds before sowing, it is crucial to avoid seed damage by the machine working bodies to obtain the planned harvest. For that reason, when designing new machines, it is necessary to exclude the use of auger working bodies and reduce the treatment speed. This paper analyzes the interaction of seeds with the working surfaces of centrifugal disk distribution bodies of pressown seed treatment machines. This paper considers the influence of geometric and kinematic factors on the distribution of particles at the outlet of the disk working body. Theoretical dependences that allow determining the relative speed of seed escape from the blades of a centrifugal disk have been obtained. An experimental plant allowing testing of the effectiveness of the proposed technical solution has been designed and manufactured. Theoretical and experimental studies allowed us to determine the conditions necessary for uniform chemical treatment of seeds and reduce the impact of centrifugal-type working bodies on seeds when treated with chemical or biological preparations before sowing.
