Under the current conditions of price growth, the expansion of agricultural enterprises and the creation of new ones based on them, the economic feasibility and practical possibility of purchasing the necessary equipment has significantly decreased. In connection with this and with the aim of expanding the functional capabilities of the technical means available in farms, the application of devices to serial machines is becoming more and more effective. The article presents an overview of modern attached screw equipment for quick unloading of motor vehicles. When designing screw equipment, it is necessary to take into account the peculiarities of their transport properties. The transportation of bulk goods by angle screw equipment depends on the frequency of rotation and the level of filling of the conveyor with the product. Structural and mechanical properties primarily depend on the density of packing of particles of loose material, their relative mobility. The mechanical properties of such a structure can be described by the equivalent modulus of elasticity and the equivalent Poisson's ratio. The nature of energy transfer in a loose material is largely determined by the forces of friction and adhesion at the points of contact of its particles. A characteristic feature of screw conveyors is that the screw working body is freely (without supports) located in an elastic or rigid casing and along its inner surface transports the material to the unloading area. The article presents the main theoretical ratios for determining the effectiveness of hinged screw products. A study was conducted to determine the influence of the main technical parameters on the performance of high-speed conveyors at a large angle.
