“…The movement from the engine is simultaneously transmitted to the first and second peg drums, then from the second peg drum to the third and fourth peg drums. In this case, the rotational speed of each subsequent drum is selected larger by (10)(11)(12) rpm than the previous one. At the same time, it has the ratio: ; ; ;…”

“…The main disadvantage of this design is significant damage to cotton seeds due to the large angle of rotation of the grate ribs, a significant increase in the inhibition of the cotton fly [8]. In another design of the grate, containing a pair of sidewalls with holes and space between the sidewalls are rod grates, on the end section of the axis of which elastic bushings are installed, located in the holes of the sidewalls [9,10]. The disadvantage of this design is the large escape of the fumes into the trash outlet due to the deformation of the elastic supports and an increase in the gap between the grates [11].…”

This article provides a general scheme of the principle of operation of a fibrous material cleaner from coarse and fine litter. Based on the compilation of dynamic and mathematical models, its numerical solution, the regularities of the movement of the working bodies of the purifier are presented. Analyzes of the laws of motion and graphic dependencies substantiated the main parameters of the purifier. Recommendations are given for widespread use in fiber-cleaning production.

“…At the moment on many domestic saw gins the grates made of gray cast iron are used [1]. Technological process of production of pig-iron grates includes preparation of burdening materials, metal smelting, preparation of forming mixes, production of the top and lower semi-forms, loading, filling, unloading of a form, knockout casting from a form, its cleaning, stripping, check, machining [2].…”

Results of studies on extending the time operation of gin and linter grates by hardening of the working area by high-frequency current are given in article. Mathematical models for calculation of key parameters of the mode of hardening of the working area of gin and linter grates are made. As a result of the executed researches the following conclusions are drawn: change of a gap between grates in a grate lattice leads to change of parameters of process of ginning and finally to deterioration of products. Mathematical models for calculations of parameters of process of hardening of the working area of grates are received. On the received mathematical models key parameters of hardening process current of high frequency which have the following values are calculated: depth of the tempered layer – 2.0 mm, the optimum frequency of current – 60000, specific power – 500 W/cm2, hardening time – 10, studying hardness tempered and not tempered sites of grates by method of Rockwell showed increase in hardness of the tempered site to HRC 55 against HRC 45 at not tempered by the working area.

et al. 2021

View full text Add to dashboard Cite

Article issues of decrease in amplitude of dynamic fluctuations of saw cylinders of gins and linter for the purpose of reduction of a deviation of saws from the plane of rotation and contact with saws of grates are consecrated. Mathematical models for calculation of flexural fluctuations of a shaft of a saw cylinder, taking into account intensity of placement of the mass moments of inertia, a technique of the solution of the equation of flexural fluctuations of a saw cylinder with variable intensity of weight and flexural rigidity of sections are given. Data on a new design of saw cylinders with use between the saw laying made on a polymeric basis and equipped with steel pins.
