The technologization of harvesting the dew retted flax stock

Abstract

The article analyses two non-mechanical methods of harvesting the flax stock. According to the first method the operation of picking up the stock from the line and sheaving is done by hand. After the second method the manual work includes picking up flax stock fran the line, coning, adjusting the cones in the process of field drying and sheaving. The article reviews the semi-mechanized method according to which the flax stock is picked up from the line in portions with the help of the proportioning picker ПНП-3, then the flax stock portions are manually coned and adjusted in the process of drying and picked up and sheaved by ВН-1 or ВН-2 machines the author studies the other kind of semi-mechanized method of harvesting that includes picking up the flax stock by the semimounled pickers ППТ-1,5 or the mounted pickers ПНП-3 which form portions, manual cowing for drying, semi-mechanised sheaving of the dried flax stock with the help of ВН-2 machine and loading the sheaves on vehicles by the pick-up loader ППС-3. The article also illustrates the mechanized methods of harvesting. According to one of them the process of picking up the flax stock from the line and adjusting it in hayracks for field drying is done by the picker ПТЛ-2 when fitting butts and sheaving is done by the picker ПТШ-1. From the mechanized methods of picking up the flax stock the author studies the usage of ПТП-1 and ПТН-1 pickers as well as press-picker that picks up the line and packs the flax stock in lig vertical cylindric units weighing 1,2 t. The flax stock picking up by the roll pickers which form the rolled stock packages has been illustrated separately. The labour costs for a hectar of harvested area, the number of the appropriale technical means, the power consumption of loading operations and the productive caparty of the vehicles transporting the flax stock in various packages are used as estimative indices of harvesting methods according to which the level of technologization of the harvesting is determined. By certain indices the usage of the rall press-pickers contributes to the improvement of the harvesting process techonologization. In comparison with the sheaf technology of harvesting the usage of press pickers leads to the reduction of labour costs on loading as well as the reduction of the loading process power capacity and contributes to the increase of the productivity of the vehicles for the flax stock transportation.
