THEORETICAL STUDIES OF A DESIGN OF MANURE SPRAYING IMPLEMENT FOR LOCAL MANURE APPLICATION UNDER GOURDS

The paper outlines a rational method of introducing manure under gourds. The authors carried out theoretical studies with modeling the movement of a manure particle from a manure spreader to the soil surface taking into account the technological features of the application process and the physicomechanical properties of manure. Based on the study results it has been recommended to localize the introduced manure in three rows using a special extention to the manure spreader. The authors provide indicators for a more uniform
manure application: rational combination of the installation angle and the length of dividers, as well as the location and installation angle of trays. The paper contains a relationship between the linear speed of the conveyor belt and technological characteristics. It has been established that the travel speed of manure mass along the body lags behind the speed of the manure spreader conveyor, therefore, when calculating the performance, a correction factor Ko = 0.5…0.6 should be introduced. Its lower value corresponds to the minimum feed, and the upper limit – to the maximum. To divide the manure stream into three equal parts, it is necessary to install the fasteners of the lower edge of dividers at a height of 0.64 m and maintain the belt conveyor speed within 0.25…0.44 m/s.
