Ensuring the operating modes of the seeding apparatus specialized equipment

Abstract

The subjects of the research are the process of sowing seeds with a seeding apparatus and the indicators of quality of their distribution in a row. The goal is to substantiate a rational technological process of distributing row crops seeds in a row with a pneumatic seeding apparatus. Special equipment was used in the system of ensuring the revolutions of the seeding disc, sucking seeds to its holes, pneumatic transport of seeds after separation from the opening of the seeding disc for contact interaction with the receiving platform of the sensor of the number of seeds and its settling in the collector. The novelty of the research lies in the use of an acoustic sensor for a single registration of the sowed seeds with a short time interval, which makes it possible to assess the quality of the operation of the sowing device by the standard deviation of seeds from a given seeding rate in their normal distribution in accordance with the law of numbers. The operating mode of the pneumatic seeding apparatus from specialized equipment as part of the test bench was carried out as an example of sowing sunflower seeds with a seeding rate of 3 seeds/linear meter for the conventional seeder speed of 9 km/h. The data obtained with different time intervals between the registered seeds in WAV format by the PTC Mathcad Prime software was represented by classical distributed seeds in graphical form and data in tabular form. The quality indicators of seeds for sowing and their class distribution in a row by rational operating modes of the seeding apparatus, assessed by specialized equipment when applying the law of large numbers, are the basis of scientific research on predicting the yield of row crops.
