Interaction of the bar-plate conveyor of the machine with mineral fertilizers

Abstract

Annotation Purpose. Determining the impact and interaction of the bar-plate conveyor with the mass of fertilizers to justify the choice of its parameters and mode of operation, ensuring the stability of the process. Methods. Theoretical calculations, their analysis. Results. The structural scheme of the process of mineral fertilizers leakage by bar-plate conveyor through the unloading window is substantiated. The effectiveness of fertilizers largely depends on the correct combination of methods of their introduction into the soil. There are two ways to use fertilizers: continuous surface sifting and internal soil application. Depending on the terms and norms perform basic and pre-sowing application, as well as fertilization [1]. Centrifugal mineral fertilizer spreaders, which use disks with the possibility of making the working mixture on the surface at an angle to the horizon have become widespread. This is due primarily to the versatility of the tool, in which due to the reorientation of the disk you can get high quality fertilizers and achieve high widths of spread. Conclusions. The results of the kinematic analysis showed that the theoretically possible uneven distribution of mineral fertilizers can reach 34–60%, in fact it is less due to the elasticity and shedding of fertilizers. To reduce the uneven distribution in the design of the machine, we have provided an intermediate hopper with an inclined auger, due to which we were able to significantly reduce the intermittent supply of mass by the conveyor. Secondly, due to the auger, we have achieved the versatility of the machine: after removing the centrifugal working body, the machine can be used for other work.
