Machines for crushing and spreading manure for family dairy farms

Increasing soil fertility requires high-quality preparation and timely application the doses of organic fertilizers. The quality of organic fertilizers is ensured by the preparation fertilizers using universal machines. The use of mobile machines for shredding and spreading manure on livestock farms makes it possible to prepare high-quality organic fertilizers. The analysis of organic fertilizer spreaders with different working bodies, construction is carried out in the work. The advantages and disadvantages listed of machines for grinding and spreading manure, such as PRT-10 ROU-6, RTD-5, MTU-10. According to the technical characteristics, the model for spreading manure on a small farm was chosen. Improved design of the feed shredder based on PRT-10. The basket has established corps placed in it with the mixing chamber with a paddle drum, the sealing conveyor. In the front part of the frame there is a manure pump driven by the GDP of the tractor. The paddle drum is made in the form of a shaft with articulated - articulated blades. The sealing conveyor can be installed at different angles, thus adjusting the thickness of the straw that is served into the mixing chamber. The work analyzes dependence of the efficiency of using mobile machines for grinding and spreading organic fertilizers in the direct operating costs for small family farms. It is established that the efficiency of using the machine for grinding and spreading of organic fertilizers PRT-10 is the highest, which makes it possible to operate the machine on small dairy farms. On family dairy farms it is advisable to use mobile mixers PRT-10. It is the most efficient to use. Its universal design allows us to upgrade the drum for shredding manure, which makes it possible to stack the resulting manure mixture in piles and to apply manure to the fields
