Justification of parameters of vehicles with elastic partitions for transporting potatoes

Elastic partitions have been developed to be installed in the body of a vehicle and allowing to reduce damage to tubers when unloading by reducing the speed and, accordingly, the interaction of potatoes with the working surfaces of the machine and neighboring tubers. A mathematical model of a device for transporting and unloading root crops has been developed, taking into account the physical properties of root crops, the physical and geometric characteristics of the container and elastic partitions, as well as the parameters of the unloading process. As a result of comparative field tests of a serial MAZ 5516 truck body and an experimental MAZ 5516 truck body with installed transverse partitions, it was found that the use of the developed elastic transverse partitions reduces damage to potato tubers from 5.3% to 2.9%.</jats:p

Theoretical study of unloading the body of vehicles equipped with elastic partitions

For transporting potatoes, it is proposed to equip the vehicle with elastic partitions. Elastic partitions are formed by tubes of elastic material and can rotate around the axis of the transverse partition. A model has been developed that allows one to take into account a large number of parameters of root crops, a vehicle body, elastic partitions, parameters of the unloading process, and also calculate the main indicators of the efficiency of unloading root crops. As a result of optimization, it has been found that the optimal length of the elastic tube is 1.58 m (when the height of the vehicle body is 1.60 m), the optimal coefficient of bending stiffness of the tube is 0.9 kN/m2. At the same time, the unloading time will be less than 11.5 s and the share of damaged root crops will be less than 4.0%.</jats:p

The Effect of Humic Aerosol Treatment on Grain Seeds Quality

Introduction. According to experts, in the coming years, the world market of organic products will continue to grow at a rate of 15-16% per year. The growth will equal about 20% of the world market of all agricultural products by 2025. In this connection, of a particular interest is the development of elements of agricultural technologies for the use of soil-improving substances and growth regulators of natural origin, including humic preparations, which provide for sufficiently high yields of agricultural products. Materials and Methods. The methods of using humic preparations were investigated on the example of spring barley seeds, treated with the traditional semi-dry method and using hot mist. Germination of seeds in the laboratory was carried out according to the Russian State Standard GOST 12038-84. The laboratory data were subjected to mathematical processing by the method of variance analysis. Results. The treatment of seeds with humic preparations led to an increase in sowing qualities, regardless of the method of seed treatment. However, the comparative efficiency analysis of the pre-sowing treatment of the test crop seeds with the aerosol and using the semi-dry method showed that the use of the developed equipment made it possible to increase the biological activity of humic preparations, which brought about an increase in the growth and biometric parameters of seedlings. Discussion and Conclusion. The treatment of spring barley seeds with humic preparations has some positive effect on their sowing and yield qualities. The strongest positive effect was obtained when treating seeds with reduced sowing qualities, which was quite often observed when harvesting seed crops in years with unfavorable conditions: heavy rainfall, lack of heat, as well as in violation of the technology of harvesting and preparing seeds. Our experimental studies showed that the use of the developed device for treating seeds with hot mist reduces energy costs and increases processing efficiency.</jats:p
