Theoretical Aspects of Plant Material Sealing in a Wedge-Shaped Canal

The Heap Parts Movement on the Shareboard Surface of the Potato Harvesting Machine

“…The study of the movement of the blade in the potato heap (Figure 2) will be based on the following assumptions: a) The relative velocities of the particle before and after collision with the blade lie in the same plane with the normal to the surface, the impact of the particle on the surface is considered absolutely inelastic (the coefficient of recovery is zero) [7]; b) The force of resistance to the movement of the particle in the space between the surrounding fixed particles is opposite in the direction of the vector of its absolute velocity; c) The reaction of the surface applied to the particle coincides in the direction with the absolute speed of the particle; d) The displacement resistance of the group of particles that fill the playground dF is proportional to the size of the playground [10].…”
