The mass second-oriented flax stock advance to baler and flax stock rolls

Abstract

The paper considers the use of ПР-1,2Л flax baler with the baling chamber of accessory volume and ППР-110 hax baler with the baling chamber of constant volume. The mass second-oriented flax stock advance to balers amounted to 0.39 kg/s, 0.66 kg/s and 0.81 kg/s respectively. Along with the increase in the mass second-oriented flax stock advance the density of rolls, the damage of stalks in them and the mass of rolls decrease according to the line with negative angular coefficients, whereas the linear mass of stalk layer in the roll increases according to the lines with positive angular coefficients. The lines which interpret the change in the roll density related to ПР-1,2Л baler with the roll density controller in the basic position and ППР-110 baler with the roll density controller in the minimum position almost coincide. It means that the intensity of decreasing the roll density in the investigated balers along with the increase in mass second-oriented flax stock advance proves similar under any position of roll density controller. The same concerns placing the density controller in ПР-1,2Л baler to the maximum position, and in ППР-110 baler – to the basic position. The lowest intensity of decreasing the density of rolls along with the increase in the mass second-oriented flax stock advance is characteristic of ПР-1,2Л baler under the placement of roll density controller to the minimum position. The highest intensity of decreasing the density of rolls along with the increase in the mass second-oriented flax stock advance is characteristic of ППР-110 baler under the placement of roll density controller to the maximum position. Over the investigated range the change in the mass second-oriented flax stock advance its damage proves higher in the rolls formed by ППР-110 baler. In accordance with the research conditions the damage which does not exceed 10 % can be provided under the exploitation of ПР-1,2Л baler over the entire investigated range of the change in the mass second-oriented flax stock advance and the placement of the roll density controller to various positions. According to the research conditions when using ППР-110 baler the damage of stalks which does not exceed 10 % was observed only under 0.81 kg/s mass second-oriented advance and under the placement of roll density controller to the minimum position. The character of changes in the mass of rolls depending on the mass second-oriented flax stock advance, the placement of the roll density controller to various position and under the use of ПР-1,2Л and ППР-110 balers is similar to the character of changes in the density of rolls with respect to the same argument. For instance, when using ПР-1,2Л baler with the placement of the roll density controller to the maximum position and ППР-110 baler with the placement of the roll density controller to the basic position the absolute terms of the line equations of the changes in the mass of rolls depending on the mass second-oriented flax stock advance amount to 143.15 and 143.30, and under the angular coefficients in the same sequence – to 48.14 and 48.67. Accord-ing to the experiment data, under the mass second-oriented flax stock advance of 0.39 kg/s, 0.66 kg/s and 0.81 kg/s the rolls formed by ПР-1,2Л and ППР-110 balers with the placement of the roll density controllers to the above positions had a mass of 124 and 124 kg, 111 and 112, 104 and 103 kg respectively. With respect to the increase in the mass second-oriented flax stock advance the linear mass of the layer of stalks is increasing according to the linear dependences and proves more intensive in the rolls formed by ППР-110 baler. Along with the increase in the mass of rolls formed by the balers under study their density increases according to the same linear dependence, and the damage of stalks in the roll increases more intensively in the rolls formed by ППР-110 baler. Along with the increase in the density of rolls formed by ПР-1,2Л and ППР110 balers the damage of stalks in the rolls increases according to the law of lines and proves somewhat more intensive in the rolls formed by ППР-110 baler.
