Annotation Purpose. Improving the efficiency of pesticide use by developing a batch-type rotary seed treater for layer-by-layer seed treatment, which will improve the quality of seed treatment and environmental safety. Methods. The study used an analytical and computational method using a software environments Microsoft Office. Results. A structural-functional diagram of a rotary treater of periodic action for the layer-by-layer application of protective-stimulating-nutrient preparations to seeds has been developed, which involves the use of a seed treatment chamber with a vertical rotor installed in it, to which seeds and components of chemical preparations are sequentially applied to the seeds. A relationship has been established between the productivity of the seed treatment process and the mass of the treated seed portion, the loading time of the seed portion, the time of processing the seed portion, the drying time of the treated seed portion, the unloading time of the treated seed portion and the number of applied layers of preparations. Conclusions. The productivity of the process of layer-by-layer seed treatment increases significantly with an increase in the mass of a portion of seeds and sharply decreases with an increase in the number of applied layers of preparations. The productivity of two-layer seed treatment varies from 0.97 t/h with a mass of a portion of seeds of 10 kg to 13.62 t/h with a mass of a portion of seeds of 140 kg, the productivity of six-layer seed treatment varies from 0.4 t/h with a mass of a portion of seeds of 10 kg to 5.66 t/h with a mass of a portion of seeds of 140 kg. Keywords: portion of seeds, disinfectant, layer-by-layer processing, protective-stimulating-nutritious preparations.

Purpose. To determine promising directions for the development of the technical and technological foundations of soil cultivation in the conditions of climate change. Methods. Monographic, abstract-logical, graph-analytical, induction and deduction, regression analysis of results. Results. Modern soil cultivation technologies are considered, their advantages and disadvantages, development trends are defined. It has been established that climate change will significantly affect the terms of execution of works, the conditions of interaction of working bodies of technical means with the soil environment. The parabolic relationship between traction resistance and soil moisture means that climate change will increase fuel costs for tillage. Therefore, the further search for new technical and technological solutions should be aimed at reducing energy consumption and preventing physical degradation of soils, substantiating structural and functional schemes of technical means for soil cultivation, parameters of working bodies and modes of operation, under which the number of dust particles in the surface layer of the soil will be minimal. Conclusions. The main direction of the development of the technical and technological base for the production of plant products in the conditions of climate change is the harmonization of the interaction of the working bodies of tillage machines with the soil, which will ensure the reduction of physical soil degradation and energy consumption to create a favorable environment for plant development and crop formation. In the conditions of global climate change, agricultural production is being reoriented towards precision farming systems, therefore, crop production technologies should be based on targeted tillage with the simultaneous introduction of a full dose of mineral nutrition into the seed sowing area for the planned harvest, sowing of seeds and preservation of plant residues on the surface of the soil for protection it from overheating and loss of moisture. Keywords: technical means, soil cultivation technologies, interaction of working bodies with the soil, soil moisture, soil resistance, energy consumption, physical soil degradation.

Purpose. To increase the efficiency of technological processes (TP) of sugar beet harvesting (ZTSB) by substantiating the rational seasonal loading of the beet harvester SKS-624 “Palesse BS624-1” at different times of commencement of harvesting operations, as well as to establish the regularities of changes in the functional indicators. Methods. The research uses the methods: analysis and synthesis of SBH TP components for the theoretical definition of efficiency factors; system-factor and system-event approaches to reveal their influence and reflection in the statistical simulation model of the SBH TP; statistical simulation to determine functional performance indicators of TP; iterations of the simulation model for displaying the stochastic agrometeorological and biological-substantive components; correlation-regression and statistical analysis of the computer experiments results. Results. It is emphasized on the importance of taking account of agrometeorological and biological-substantive components for the coordination of the SBH beginning time and their production area with parameters of technical support (beet harvesters and trailers-reloaders of root crops). The features of SBH TP are singled out, which should be taken into account in their statistical simulation model. The statistical simulation was performed, results were generalized and the dependencies of the functional efficiency indicators of these TP for the given beet harvester – SCS-624 “Palesse BS624-1” were established. It has been shown that the choice of the harvest beginning time does not allow simultaneously to minimize biological and technological losses of sugar beet root crops. The optimum sugar beets production area for the considered beet-harvesting combine is substantiated and the dependence of this area with the beginning time of the harvesting TP is shown. The harvesting beginning time and sugar beet production area has been agreed with the parameters of a beet harvester. The minimum specific unit costs of the technological system are achieved. Conclusions 1.The computer experiments results with the statistical simulation model SBH TP (for the beet harvester SKS-624 “Palesse BS624-1” and the trailer-loader roots – HTZ-243K.20 + Hawe Ruw 2500T) convinced that the choice of rational beginning time of the TP will not allow to reduce the biological and technological losses of the crop to an absolute minimum. This is the basis for using the cost criterion to justify the parameters of the relevant technical support. 2.The usage of the developed methods and models, as well as the combination of the production and computer experiments results, made it possible to prove the possibility of substantiation of the technical support parameters of SBH TP on the basis of their agreement with the beginning time of the TP and the sugar beets production area. In particular, it was found that shifting the beginning time of these TP in relatively recent calendar terms (from 260 to 285 da

Annotation Purpose. Improving the efficiency of the manual vibro-impact fruit shaker by studying the parameters of oscillations of the handles during the operating mode of shaking to justify the maximum accelerations that can be transmitted to the hands of the worker. Methods. The main provisions of laboratory and field experiments using modern measuring equipment for measuring accelerations are used. Results. The parameters of oscillations of the holding handles of the manual vibrating shock shaker of fruits are investigated. The method of measuring local accelerations transmitted to the hands of the employee has been improved. It is proposed to use accelerometers ANS 114-02, which are attached with adhesive tape to the holding handles of the shaker along the x and y axes of the orthogonal coordinate system. The y-axis is directed in the direction of oscillation and coincides with the longitudinal axis of symmetry of the handles, and the x-axis – along the forearm of the worker perpendicular to the y-axis. The estimation of the admissibility of the total vibration on the shaker handles was carried out according to the method, which consists in determining the root mean square values of the accelerations of longitudinal-vertical oscillations in the frequency bands up to 31.5 Hz. The oscillating loads on the handles of the manual fruit shaker operating in the vibro-shock mode are investigated. At the same time, local oscillations of non-constant action are transferred to the hands of the worker during working hours. The studies were performed at the highest perturbing forces in the range of operating shaking frequencies of 40–100 rad/s (6.37–15.92 Hz) on skeletal branches with a diameter of 90 mm at the base. Frequency-adjusted root mean square accelerations on the holding handles do not exceed the allowable values. Conclusions. Oscillatory loads on the hands of the worker through the handles, ensuring the retention of the manual vibratory shock shaker, do not exceed the allowable short-term local oscillations on the adjusted values of the root mean square acceleration and are: along the y-axis – 2.47 m/s2 (78.3 dB); along the x-axis perpendicular to the y-axis – 0.63 m/s2 (66.4 dB). Keywords: manual fruit shakers, holding handles, local oscillations, acceleration.

The parameters of oscillations of the holding handles of the manual vibrating shock shaker of fruits are investigated. The method of measuring local accelerations transmitted to the hands of the employee has been improved. It is proposed to use accelerometers ANS 114-02, which are attached with adhesive tape to the holding handles of the shaker along the x and y axes of the orthogonal coordinate system. The y-axis is directed in the direction of oscillation and coincides with the longitudinal axis of symmetry of the handles, and the x-axis – along the forearm of the worker perpendicular to the y-axis. The estimation of the admissibility of the total vibration on the shaker handles was carried out according to the method, which consists in determining the root mean square values of the accelerations of longitudinal-vertical oscillations in the frequency bands up to 31.5 Hz. The oscillating loads on the handles of the manual fruit shaker operating in the vibro-shock mode are investigated. At the same time, local oscillations of non-constant action are transferred to the hands of the worker during working hours. The studies were performed at the highest perturbing forces in the range of operating shaking frequencies of 40–100 rad/s (6.37–15.92 Hz) on skeletal branches with a diameter of 90 mm at the base.\u0000Frequency-adjusted root mean square accelerations on the holding handles do not exceed the allowable values.\u0000Conclusions. Oscillatory loads on the hands of the worker through the handles, ensuring the retention of the manual vibratory shock shaker, do not exceed the allowable short-term local oscillations on the adjusted values of the root mean square acceleration and are: along the y-axis – 2.47 m/s2 (78.3 dB); along the x-axis perpendicular to the y-axis – 0.63 m/s2 (66.4 dB).\u0000Keywords: manual fruit shakers, holding handles, local oscillations, acceleration.","PeriodicalId":253322,"journal":{"name":"Mehanization and electrification of agricultural","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124936620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Annotation Purpose. Establishment of theoretical regularities that make it possible to make such a choice of parameter values for a trailed disc harrow, which provides it with the desired directional stability, which, in turn, ensures a high-quality performance of the technological process for the disc-type machine-tractor unit. Methods. The methods of the theory of agricultural machines were used for the research, analytical mechanics, higher mathematics, and methods of numerical calculations using a PC. Results. According to the results of the study, it has been established that sufficient directional stability of a trailed disc harrow can be ensured with the correct choice of its width of capture, distance from the point of attachment to the center of resistance and the speed of the working movement. The optimal combination of these parameters of the disc harrow determines the maximum performance of the harrow machine-tractor unit with a satisfactory stability of its movement in the horizontal plane, which is provided after their determination using the obtained new analytical dependencies. Soil disking is one of the methods of soil cultivation, which ensures its effective crushing, loosening, partial mixing and wrapping. Despite numerous researches of the disc harrow operation process, insufficient attention is still paid to the research of the motion stability of harrow machine-tractor units, especially trailed ones. Conclusions 1. Satisfactory directional stability of the trailed disc harrow can be ensured with the correct choice of its working width, distance from the point of hitch to the center of resistance and the speed of the working movement. 2. The optimal combination of the design parameters of the disc harrow and the speed of the harrow machine-tractor unit, which determines its maximum productivity with satisfactory stability of the disc harrow movement in the horizontal plane, is ensured when they are determined using the new analytical dependencies. 3. The obtained theoretically mathematical dependencies can be used to solve a similar problem with respect to any other symmetric machine-tractor unit with a trailed technological part. Keywords: harrow, tillage, trailed machine-tractor unit, motion stability, differential equations.
