The combination feeder of a continuous-action loader for the bulk load

Abstract

The spectrum of construction, industrial, agricultural and other bulk load includes a lot of names that vary in their physical, mechanical and volume-mass characteristics. Continuous-action loaders are developed and constantly improved for bulk load shipping. Their main operating element, which is responsible for the efficiency and power consumption of the drive, is a feeder. The feeder separates or grabs the load from the surface on which the bulk load is stored. It is proposed to use a combination feeder consisting of two operating elements, that will allow to grab the load and transport it simultaneously. The kinematic analysis of the feeder operation and its interaction with the load has been carried out. We have derived the parametric equations of the blade motion when the loader is traveling and the shaft is rotating in the coordinate form. Relying on the length of the blade trajectory, it is presented the expression for the determination of the continuous-action loader with the combination feeder efficiency. The efficiency depends on the physical and mechanical properties of the load, operational and design specifications of the feeder.

“…Уменьшение производительности при ω > 4,5 рад/с связано с тем, что при большой угловой скорости корнеклубнеплоды не успевают опуститься с лопастей в выгрузное окно на отгрузочный транспортер. Поэтому частично перемещаются лопастями обратно в бурт, что приводит к снижению производительности [3,4]. Данный характер зависимости имеет место у других вращающихся рабочих органов погрузчиков непрерывного действия [5][6][7].…”
