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 80
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 202
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 36
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 STUDY OF THE PROCESS OF SEPARATION OF TOBACCO LEAVES FROM THE STALK

abstract 1261702022 issue 126 pp. 289 – 303 28.02.2017 ru 119
The article presents a constructive-technological scheme of leaf separating apparatus for harvesting tobacco leaves. We have performed a theoretical analysis of the process of separating tobacco leaves from the stalk. The dependences characterizing the trajectory, speed and acceleration of an arbitrary point of the cutting edge of the drum were obtained
