Experimental sample of a flow distributor of stem materials from rolls

Abstract

Annotation Purpose. To create an experimental sample of the flow distributor of stem materials from rolls on the basis of the feeder type KTU-10, by development of conveyor and biter cutting working bodies of the current principle of action for small-volume separation and delivery of rolled stem forage and litter materials and the stand for laboratory researches. Methods. Analysis of existing technological schemes and technical means for grinding rolls of stem fodder. Computer programs for modeling objects of technological processes and parameters of technical means (KOMPAS 3, Mathcad, Matlab + Simulink). Results. Taking into account the shortcomings of the parameters of the existing blowers, a structural and technological scheme of the universal distributor of loose and formed into bales and rolls of stem materials was developed and an experimental sample was created on the basis of a narrow-sized KTU-10 feeder using knife sliders and sliding cutters. The equipment can grind and distribute hay and straw of any humidity in rolls, bales, and placer. The stand for laboratory researches of an experimental sample is prepared. Conclusions. The analysis of technical means for the use of rolled stem materials on cattle farms revealed that on about 1000 farms in Ukraine the distribution of stem rolled and baled materials is performed using manual labor, as special tools have high energy consumption (power – 45–95 kW), material consumption (weight – 1150–3950 kg), cost (150–450 thousand UAH) and operating costs. To solve the problem, the structural and technological scheme of the distributor of placer and rolled stem materials on the basis of the widespread KTU-10 feed distributor with the use of a new block of knife beaters of sliding cutting with inertial anti-cutting support and end feed of bales and rolls is substantiated. An experimental sample of the distributor of rolled stem materials on the basis of the small-sized distributor KTV-3.5 (KTU type) with the independent electric drive of working bodies with a power of 5.5 kW which is used for researches of laws of the updated process is developed. The stand for laboratory researches of an experimental sample is prepared. Keywords: experimental sample, rolled stem materials, working bodies, knife beaters, design and mode parameters.
