This article deals with the rules of observance of agriculture technology requirements for the production of potatoes in particular. On the example of the combine PDA 1.2, we have considered the places having the greatest damaging effect on roots. One can also find a summary procedure for calculating the probability of defective products
One can see some density irregularity within the roll
in the baler with a chamber of constant volume. We
have found out that the maximum density of hay roll
width (the baler width) is observed in the middle part.
This is due to the shape of the hay roll entering the
baler. To even the hay rolls they have mounted some
rotating disks having some inclined spring pins above
the baler. To improve the roller distribution the disks
above the baler have been pushed forward forming a
tapering gap. The evening discs rotating above the
moving roll will cause some relative motion of hay
particles. The interaction of the evening disks with
the hay roll in the vertical plane will be determined
by the elasticity of the hay roll and the weight of the
frame with the disks. We have studied the trajectories
of hay particles motion with the help of MathCad
program. We have had the following initial
parameters: the degree of compaction (decrease of the
roll height when evening), the friction coefficient, the
angle rate of the evening disks, the number of pins and the speed of the hay roll. As a result we have got
the trajectories of the hay particles motion when the
evening disks functioning. The analysis of the
trajectories has allowed to establish some basic
parameters of the evening device such as the distance
of 0.15…0.2 m between the pins; the degree of
compression while evening 20...25 %, the angle rate
of the evening discs 23...30 rad / s and the diameter
of the evening disc 0.74 m. The application of the
evening device in the form of the disks with pins
provides a uniform distribution of hay particles
edgewise of the baler ensuring preliminary hay roll
seal press before passing to the baler pressure
chamber that contributes to getting the rolls with
larger mass and a uniform distribution of hay density
inside the roll
