The development of a new family of technological superstructures for agriculture on the basis of a specialized agricultural vehicle
Special off-road and agricultural trucks including those which are capable of operating in the field being equipped with various machines and units are needed to solve the problem of agricultural machinery development in the Russian Federation. These trucks, though different in lifting capacity, total weight, the opportunity to work with a removable processing equipment, are adapted to the specific operating conditions and meet the agronomic requirements. The development of technological superstructures on Ural-432065chassis has been carried out with application of advanced methodical achievements of domestic and foreign experts in the field of agricultural machinery. The legal documents of the Russian Federation as well as state standards related to the production of agricultural machinery were taken into consideration. The technological add-ins provided: high performance and quality of mineral granular and liquid organic fertilizers; comfortable environment for the operator; environmental characteristics at the level of modem requirements; prevention of crushing the pellets and reduction of dust (in the process of fertilizing); improvement of freight transport and engineering performance. On the basis of Ural-432 065 chassis twelve replaceable technological modifications of add-ins were suggested. Their layout schemes and some technical parameters were shown. The proposed technical and technological solutions were to ensure the cost reduction of mass-produced products if compared to the cost of imported analogues. The analysis of the effectiveness of the proposed technical solutions showed that the use of Ural-432065 truck with technological add-ins when compared to tractor transportation and technological aggregate resulted in the decrease of operating costs by 48%; labor costs were 43% lower; consumption of diesel fuel was decreased by 38%.
