| description | During a sowing grain is damaged because of movement on a surface of working elements. It leads to formation of cracks, to destruction and damage of seed material and as result productivity reduces and received grain has lower qualityof. The authors researched a movement of caryopsises during a sowing taking into account the speed of the movement, weight, friction and resistance forces, and other factors. At the movement on a distributive plate of a disk coulter seeds meet the cylindrical pins and change the direction of the movement that makes it possible the uniformity distribution. Their coordinates during each certain period of time were determined by system of the recurrent algebraic equations. Thanks to this system it is possible to define at each stage an arrangement of caryopsises, a trajectory of their movement after contact with pins. The main advantage of such method is that on each step it is possible to know the provision of a particle and to change the direction of a trajectory of its movement if it will be necessary. This problem was solved numerical due to the program «Plastina. For a plate with width 0.075 m and length 0.175 m long, by a step of time 0.0001s the authors made the cyclic procedure describing a trajectory of the particle movement. To define the further direction of a trajectory of the movement of a particle after its collision with an obstacle the authors applied probabilistic approach and invoked a random number generator. We studied a form of a distributive plate after modeling of the movement of a particle. The optimum position of seeds on a distributive plate with pins covered with rubber material reduces damage of caryopsises, improves their quality that provides optimum placement in soil at sowing |
