Parameters of the feeder of the rotary manure spreader from piles

BACKGROUND: Organic fertilizers play an important role in agriculture, contributing to increasing soil fertility, maintaining nutrient balance and protecting the environment. Their application will allow agriculture to achieve high growth, as well as preserve natural resources for the next generation. Organic fertilizers are becoming an integral part of agricultural practices, and also contribute to the local transition to sustainable agricultural development. The development of new principles and methods of applying organic fertilizers, taking into account the state of soil fertility and the size of sites located on various reliefs, is one of the most important tasks. To reduce the energy intensity of the process and increase the uniformity of the distribution of organic fertilizers in small-scale fields, we propose to use a pile spreader without forming a roll.

AIMS: Determine the structural and kinematic parameters of the blade feeder of a machine with a rotary working body for spreading manure from heaps, allowing in specific conditions to ensure maximum possible productivity and uniformity of application.

MATERIALS AND METHODS: To reduce the energy intensity of the process, when introducing the working bodies of the spreader into a pile of fertilizers, it is possible to use a feeder - shredder installed in front of the rotor of the thrower. The rotary spreader pump was selected as the object of research. Theoretical studies have been carried out using the methods of classical mechanics.

RESULTS: In this paper, the main relationships between the structural and kinematic parameters of the rotary spreader feeder when applying manure from heaps, taking into account its technological properties, are obtained, and formulas for calculating the energy parameters of the feeding working body are given.

CONCLUSION: The expressions obtained will make it possible to conduct theoretical studies and justify the operation of a rotary manure spreader from piles. This will allow us to develop algorithms for choosing rational parameters of the proposed feeder when applying manure from heaps.
