Пневмосистема гідропневматичного висівного апарата

Abstract

Розроблено і побудовано лабораторну модель гідропневматичного висівного апарата, використання якого як ручної сівалки потребує вирішити ряд завдань, зокрема забезпечити сівалку пневматичною системою. Наведено результати досліджень агрегатів пневмосистеми для ручної сівалки однонасіннєвого висіву насіння овочевих культур з гідропневматичним висівним апаратом, а також формули для інженерного розрахунку основних параметрів пневмосистеми. The urgency of the problem. The proposed method odnosno coordinate minutnogo seed in bridged farming was implemented in a laboratory setting, the experiments which confirmed the efficiency of the hydropneumatic sowing device (HSD). The use of a metering device for piece selection of seeds from seed tanks and feeding it into the zone of sowing allows to expand the scope of HSD.Purpose – justification of the parameters and the choice of devices for manual pneumatic hydro-pneumatic seeder with metering system.The results of the research. For HSD desired air pressure in the range of 0,08–0,15 MPa. When using this device in the composition of pavement of the machine you can use your existing pneumatic equipment, and to manually drill the equipment you need to create.As a compressor you can use car mencompare for inflating tires. The disadvantage of such compressors is excess capacity (30–40 l/min), large enough capacity that requires special power source to 12 V, 15–20 amp DC. In addition, cheap car mencompare have insufficient reliability and durability.Significant reliability and durability inherent in hermetischen motor-compressors of household refrigerators (MTBF 25000 hours, the guaranteed period of operation – 15 to 20 years). As a rule, dispose of come refrigerators, the compressor which did not work the full resource and can be used for different needs not on the main purpose.The results of the work on the creation of the pneumatic system for manual hydro-pneumatic seeder with metering system prove the possibility of using the motor-compressors disposed household refrigerators. The dependences allow to perform engineering calculations units of pneumatic system.
