Abstract:The purpose is to investigate substantiate relative position working bodies of improved plow-ripper. Scheme of the plow-ripper is given. The plow-ripper consists of the left and right sections, a ripping share established down the axle of symmetry tool, improved working bodies with inclined racks. Analytics dependencies are mined to define distance between working organs and the distance between them along the plow-ripper. Experiments have been carried out come true the relation stance working bodywork. Experi… Show more
The article presents the results of finding the optimal combination of the selected factors having the minimum value of the indicator of uneven leveling of the pile on the dryer conveyor, an experiment was conducted, including 8 experiments, constituting a semi-replica of a complete factorial experiment of the type 2859+3, and a program of steep ascent along the response surface was performed. The experiment was carried out three times in a randomized order. In addition, an experiment planning matrix was built using a well-known technique. Based on the results of the experiment, regression coefficients were calculated and their statistical evaluation was carried out. To verify the adequacy of the presented experimental results, the calculated value of the Fisher criterion was determined by a polynomial of the first degree and compared with tabular values.

The development and creation of energy-saving machines and technologies for high-quality basic processing is one of main tasks today. The existing step plows for smooth, row less plowing have a number of disadvantages. With these plows, the technology of smooth plowing is carried out in conditions of a closed furrow, as a result, they do not ensure the turnover of layers the required degree and the sealing of plant residues, and also have a high energy intensity. The purpose study is to substantiate the parameters the disk angle stepped plow. Theoretical studies were carried out using the methods of classical mechanics. Analytical expressions have been obtained to determine the permissible distance of transverse discarding of soil particles by a disk angle and the range of flight of soil particles under the action disk, depending on its parameters. Theoretical studies have established that the permissible distance of transverse discarding of soil particles by a disk angle should be no more than 29 cm. The analysis of the expressions obtained showed that with an increase in the diameter disk angle-lift, its angle of installation to the pressure of movement, the angle of inclination to the vertical of depth of processing the angle-lift, the range of transverse rejection of soil particles increases. To ensure the established distance of soil discarding, the diameter of the disk angle-lift should be no more than 480 mm, its installation angle to the direction the hole should not exceed 35°, the installation angle to the vertical should not exceed 10° and the processing depth should not exceed 11 cm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
