Abstract

The most effective technology for processing, storing and using manure effluents from livestock complexes into organic fertilizers, which involves homogenizing the manure mass in a manure storage lagoon using a pontoon pump, has been substantiated. Shortcomings have been identified in ensuring the working process of pumping from manure storage lagoons and applying liquid organic fertilizers (ZHOU) to the soil, in connection with which a promising unit for transporting ZHOU from a manure storage lagoon and applying them to the soil has been justified and developed. The purpose of the article is to increase the efficiency of the process of pumping and applying ZHOU from manure storage lagoons using an improved unit. An improved design of the unit for applying ZHOU has been developed, which has a high uniformity of distribution of the working fluid over the width of the unit. The test conditions of the unit for applying ZHOU in the fields adjacent to the livestock complex are given. A method has been developed for determining the uniformity of the distribution of ZHOU along the discharge hoses of the unit. Experimental studies of the prototype unit have been carried out. Based on the results of measurements, a histogram of comparative tests with a known variant and graphical dependences of the uniformity of the distribution of ZHOU over the discharge hoses are constructed. The efficiency of the unit is determined, which consists in the uniform distribution of the working fluid of the ZHOU over the width of the unit, due to the use of a distribution dome.
