Abstract
The article is devoted to the design of the working parts of a harvesting and transport unit (HTA), which operates as a result of the joint work of a pick-up and a pneumatic loader with an assembly chamber. The parameters of their relative position are considered, ensuring the technological process of continuous transportation of plant mass into the assembly chamber. For this purpose, an analysis of the process of moving material along a belt loader and its subsequent dumping into the receiving chamber of a pneumatic loader was carried out. Analytical expressions have been obtained that make it possible to calculate the parameters of the relative position of the pick-up shafts and the loader rotor and the area of mass supply to the loader. The calculated trajectories of particle movement after leaving the belt conveyor at an angle of inclination to the horizon of 20 were constructed; 30; 40 degrees. It has been established that the working parts of a pneumatic loader (rotor blades) can be located within the mass ejection zone, i.e. 0.2-0.3 m from the point where the mass is released from the conveyor, since at these points of the trajectory the speed of movement of the material is maximum.
