Development and Validation of the Reclamation Chisel-Fertilizer’s Design

详细

A mechanism and operation principle of the original structure of the reclamation chisel-fertilizer is presented. The advantage of the design consists in the possibility of the uniform supply of the fertilizers and ameliorants to the plowing and subsurface soil layers, which ensures an increase of the fertile layer, improvement of the nutrition conditions of the plants, and, as consequence, an increase of the yield of the cultivated crops. The pressure supply of the ameliorants to the layer is carried out by a high-pressure fan with a pressure air duct, fertilizer tube, by which the fertilizer-air mixture is supplied under the A-blade. The ameliorants are supplied to the trapezoidal deformation zone of the subsurface soil layer created by the chisel working element below the furrow bottom. The calculation of the structural elements of the mechanism is given. The developed structure also allows for combining the operations on applying the ameliorants, which increase the complex criterion of energy efficiency to 15%. The use of the developed structure in the agricultural production allows keeping and restoring the soil fertility.
