Boyko V. Justification of the parameters of the trimmer of chicory root crop haulm

In the dissertation work, on the basis of a set of generalized results, a new scientific task of improving the quality indicators of cutting the remains of the pulp from the heads of chicory root crops is solved by developing and substantiating the rational parameters of the working organs of the improved trimmer, which is made according to the "passive copier-spring-loaded knife" principle. An increase in the quality indicators of the cutting of the scraps is achieved due to the improvement of the design of the cutter by springing the vertical moving thrust of the cutter's copier. The movable vertical thrust of the copier is inserted into the middle of the glass, the upper part of which turns into a cylindrical finger. The compression spring is inserted into a cylindrical finger, the upper part of which rests against the thrust plate. The lower part of the moving rod is fixed on the shock absorber. Brackets are attached to the side surfaces of the movable thrust, into the holes of which fixed fingers are inserted. The fingers are fitted with rollers that move up and down in their grooves. Based on the theoretical analysis of the process of cutting off the remains of burdock from the heads of root crops with an improved cutter, mathematical models have been developed that functionally describe the process of contact interaction of the copier with the head of the root crop depending on the main parameters of the cutter's working organs. Based on the analytical solution of the developed mathematical models and the analysis of the empirical regression equations obtained as a result of experimental studies, the main rational parameters of the cutter's working organs were substantiated.
