ENVIRONMENTALLY FRIENDLY DESIGN OF A HIGH CLEARANCE FARMING TRACTOR FOR CULTIVATION AND HARVESTING OF TALL CROPS (ON THE EXAMPLE OF TOBACCO)

abstract 1321708009 issue 132 pp. 93 – 103 31.10.2017 ru 451
Results of the research on ecological safety of utilizing high clearance tractors for cultivation and harvesting of high stalk plants are presented. Purpose of the research was to decrease damaging of high stalk plants during multi-pass harvesting by tractor parts. For increasing efficiency and competitiveness of high stalk plants decreasing prime cost of production, increasing profitability and labor productivity are required. This can be achieved by introducing complex factors, which together with other factors as complex technological and technical modernization are required. Basic direction of modernization is utilizing completely new technologies and renewal of machines. Modern tractors utilized for tobacco growing have been analyzed. Basic demands for high clearance tractor which can be used for tobacco, grape and fruit trees growing have been developed. Researches on studying the tobacco plant folding during harvesting have been carried. Scheme of high clearance tractor MTZ-80 which can be assembled with machines for multi-pass harvesting of high stalk plants without their damaging has been developed. New scheme for modernization tractor MTZ-80 into high clearance model has been proposed. It can be done by changing speed reducers and forward wheels with size 11,2x20 on size 11,2x28. This will increase clearance from 470 to 840 mm

OPTIMAL PARAMETERS OF TECHNOLOGICAL LINE FOR LOADING TOBACCO LEAVES INTO CONTAINERS

abstract 1211607068 issue 121 pp. 1098 – 1109 30.09.2016 ru 525
The article presents the research results on parameters optimization of technological line for loading tobacco leaves into containers. The aim of the research was decreasing labor expenses on preparing tobacco for artificial curing. This was achieved by line modernization utilized for loading tobacco leaves into containers. We have also developed working parts of technological line for automatic loading of tobacco leaves into containers. Researches on weight studying of tobacco leaves of 3 sorts zoned in the Krasnodar region have been carried out. Dispersion analysis has not revealed weight differences between sorts, therefore, further researches can be carried for one sort. Optimization of working part for loading tobacco leaves into containers was carried by analysis of regression equation obtained by bifactorial experiment. Irregularity of leaf position was taken as optimization criterion. It has been discovered that optimal regimes: transporter belt speed v=2,8m/s, number of transporter’s double movements n=19 min-1 can be used for uniform container loading by leaves. Researches on studying line capacity on leaves position irregularity revealed that maximal uniformity obtained when line capacity is 260 kg/h

PARAMETERS OF A DEVICE FOR MAINTAINING CONSTANT FLOW OF LIQUID IN A HYDRAULIC ROW SOWING MACHINE FOR SEEDLING PLANTS

abstract 1411807003 issue 141 pp. 19 – 29 28.09.2018 ru 581
We present results on proving parameters of the device for maintaining uniform flow of liquid in hydraulic row sowing machine for seedling plants. Main difference between row sowing in greenhouse and in field is 10 to 20 times less width between rows. Existing sowing machines (because of little width between rows) can only perform scattered sowing. A method and a scheme of the device for maintaining uniform flow of polydispersed system (working liquid – seeds of seedling plants) are theoretically proved. Parameters of the device for maintaining uniform flow of polydispersed system (working liquid – seeds of seedling plants) are experimentally proved. We have also defined the effect of pipe’s position in the tank on flow of polydispersed system out of it and the effect of polydispersed system parameters (working liquid – seeds of seedling plants) on peculiarities of hydraulic sowing technological process. Testing the experimental row sowing machine for seedling plants determined that this machine adequately performs sowing process and increases productivity 8.3 times compared to manual sowing

THEORETICAL AND EXPERIMENTAL SUB-STANTIATION OF THE PROCESS MODES OF HYDRAULIC SEEDING OF SEEDLING CROPS IN THE SOIL

abstract 1592005024 issue 159 pp. 348 – 356 29.05.2020 ru 225
The article presents results of theoretical and experimental studies on the justification and experimental confirmation of the influence of hydraulic seeding process modes on the parameters of row seeding technology for seedling crops. It is hypothesized that it is possible to ensure a uniform depth of seeding within 0.5...1.5 mm by feeding seeds into the soil by hydraulic means using a liquid. We have compiled a nomogram of the influence of the height of the initial level of the liquid and its density on the amount of pressure exerted by it on the soil. It was found that the pressure of the polydisperse system on the soil increases with both the density of the liquid and the height of the initial liquid level. Experimental studies have been conducted to study the effect of the pressure exerted by the liquid on the soil and the speed of the drill on the depth of furrow formation and the depth of wetting the soil. The article determines empirical dependences of furrow depth on the pressure exerted on it for different types of soils. It is found that the depth of soil wetting decreases with increasing speed of the drill

abstract 1521908014 issue 152 pp. 129 – 140 31.10.2019 ru 244
Transplanting seedling into the field is an extremely important period for all seedling crops, as the plant passes through basic vegetation stages. After carried analysis of seedling transplantation machines utilization it became obvious that they all have low technical and exploitation parameters. The purpose of the research was elaboration of theoretical bases for calculating parameters of a unit for seedling feeding to transplanting device, which implementation will lead to increase efficiency of transplanting. The article presents the results of theoretical researches for proving parameters of a unit for seedling feeding to transplanting device. A system of equations for acting at seedling forces during its transportation from collecting drum to feeding drum is arranged. We have also calculated nomograms for defining drum rotating frequency depending on seedling friction coefficient on surfaces of collecting and feeding drums. Parameters of pneumatic feeding drum were technologically proved. Its principle is equality of capacities of feeding unit and transplanting device. We have elaborated a nomogram for defining feeding drum rotating frequency depending on plant spacing and velocity of transplanting machine
