“…Besides geometrical and kinematic parameters, such as the type and diameter of the drum, the number of drums and their position (horizontal, vertical), the quality is also affected by the properties of manure, operating speed, the used dose, the configuration of the ground, etc. The most important results of the research in this area, mainly from the perspective of comparative assessment, include research at the Institute of Agricultural Technology in Tänikon (Switzerland) (Bernik et al 2003;Duhovnik et al 2004).…”

The study focused on the definition of the impact of the parameters of the applied manure spreaders (loading capacity, size of tyres, the number of driving wheels) on the numerical values of the basic exploitation indices and on soil compaction as well. Research tests were carried out on farms of different arable land areas. The scope of the study included questionnaire surveys, laboratory and exploitation tests, comparison evaluation of fertilization units, verification of the acquired results, as well as recommendation for practical use. A significant growth in productivity (from 0.38 to 1.15 ha/h) was observed together with an increase in the loading capacity of the spreaders, but the following indicators were found to have decreased: surface of soil compaction (from 44 to 15%), field loading (from 412 to 165 kN∙km) and grooves volume (from 165 to 67 m3). Four-wheel spreader of 20 t loading capacity has been characterized by two times higher values of field loading indices (357 kN∙km), groove loading (204 kN/m) and groove volume (110 m3) in comparison with a two-heel spreader with a loading capacity of 10 t.

“…In [5,6,7] the manure distribution process is studied (the interaction between manure particle and spreading equipment, the influence of the working parameters overs the distribution uniformity, numerical model for the flow in land application). In [8] the authors studied the relative motion over a rough surface of a rotary vertical axis helicoid and the movement equation were given and solved by numerical methods.…”

Experimental results on the solid organic fertilizer machine MG 5

This paper is the first of a series of works devoted to the general issues of organic fertilizer spreading machines. Although the working process of solid organic fertilizer machines does not contain a large number of random constituents, however, the basic component, the material administered, gives the random characteristic of the process. In addition, another random component that influences the working process of the machine is the interaction of the work organ that performs the tearing and distribution of the scattered material with this material, as well as the movement of the fragments of material onto the surface of the device. A third random component is the movement of the material scattered into the atmosphere. The fragments of scattered material exhibit shape irregularities due to fragments during dislocation from the mass of feed material and due to particle collisions while moving into air until the contact with the soil. Therefore, the phenomenon of spraying the organic fertilizer on the layer from the soil surface is, as a whole, a random process. Consequently, it is logical to have experimental research prioritized in the study of the work on the distribution of solid organic fertilizers. The role of this article is to present the experimental results, some conclusions and to prefigure several theoretical or theoretical-empirical research directions. The results contained in this article are basics in all the other essays related to the topic machine.

“…Bergmann spreader, Northren spreader). A manure spreader with horizontal beaters is also manufactured (West Point Design spreader, Pik Rite's Hydra-Ram spreader, Pöttinger spreader) and recently there has been an increasing number of manure spreaders with wide-angle spreading devices (e.g., Kemper spreader, Bergmann spreader [4][5][6].…”

“…The effect of manure fertilizer characteristics, specifically particle size, shape, density and strength on spreading performance has been the subject of several research papers, and was considered in detail by Duhovnik et al [5]. While defining the technical process, the authors found that the manure spreading width directly depends on the dispersal assembly (essentially an ejection assembly) of the manure spreader.…”

Abstract. In the context of protecting and maintaining the health of the population, development and implementation of technically innovative, high performance solutions for manure spreading machinery, is an important research direction worldwide and in Romania as well. Pursuing concerns of the manufacturers and researchers in the field, there is an enhanced interest in the production of equipment for fertilization, starting with classic trailers with rear delivery horizontal-axis beaters, followed by the rear delivery vertical-axis beaters, side delivery flails, and finally reaching the advanced equipment comprising a rear delivery centrifugal table with automatic flow control. Based on the theoretical relations of mass flow rate, and considering a coefficient of correction due to material compression in the hopper, one can determine the application and discharge rates that can be achieved with a manure spreader equipped with vertical rotors in different working conditions. The difference between the conveyor speed and the speed of conveyed material as well as the friction between material and the hopper walls is also considered.
