Sorghum is genetically adapted to hot and dry agroecologies and is used not only as food, but also as feed for poultry and cattle. There is a problem of increasing the yield of sorghum and reducing the high labor costs in its cultivation in the Republic of Burundi, since in general agriculture is characterized by a natural species with a predominance of food and seasonal crops, which occupy about 90% of the cultivated land. Traditional African agriculture is based on a system with individ-ual elements of intensive farming and is not well prepared for the use of high-tech machinery and tools of production. On the plots of a peasant family of about 0.8 hectares (two acres) with the help of a hoe and a machete with a shift farming system, the yield of sorghum reaches 1.0 ... 1.3 t / ha. For peasant farms in the form of production cooperatives with an area of 200 ... 300 hectares, where it is possible to conduct intensive farming and to use of modern technical units of high productivity in order to increase yields several times, there was proposed the Mounted disco-chisel harrow de-veloped in the Kuban State Agrarian University. The harrow consists of a three-girder frame, brack-ets, a disc module, disc rippers, a chisel module, chisel rippers and a packer roller. Its purpose of peeling, plowing and seedbed cultivation, thanks to a special regulating mechanism, is performed by the unit in one pass. This will help to achieve lower operating and energy costs due to the fact that tillage work is carried out in a very short time.","PeriodicalId":160902,"journal":{"name":"Traktory i sel'hozmashiny","volume":"120 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":"126142773","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}

The “sockets” for their installation in the combine are fixed on the side cheeks, which, in turn, are rigidly connected to the transverse strips, installed between them at a uniform interval along the entire length of the deck, and the transverse strips with their inner side are located on a cylindrical surface with a certain drum wrap angle. At the same time, to increase the rigidity of the transverse strips and the entire deck as a whole, below the surface of the bar tier, the transverse strips are inter-connected by rectangular ribs curved along a concentric circle of a larger radius than the radius of the working surface of the separating grid. All decks are installed on the combine with respect to the outer diameter of the drum beaters, not along a concentric circle, but with an offset. Therefore, the principal disadvantages of single-drum single-section decks are the high levels of under-threshing, loss of free grain in the coarse heap through straw walkers, and especially crushing. In this connec-tion, there is a need for its improvement, as well as the need to modernize the threshing-separating device with an improvement in the operation of the air-sieve cleaning. On the basis of prospecting studies, a single-section threshing deck protected by the RF patent was proposed. The deck consists of at least three zones. In the first zone of threshing and separation the separating grid is made two-tier, with a variable distance between the tiers by means of a variant installation under the main tier of removable bars of the grid, located on the transverse slats with a step t larger on radii than those of the main tier, passing in the middle of the step bars of the main upper tier with intervals from 0.75 to 1.25t. In the second zone of separation and threshing the separating grid with a length of 5 to 12 intervals between the transverse strips is single-tier, but the step between the grid bars located on the continuation of the tier of the first zone on the transverse strips of the zone is at least 1.5t of the step. In the third zone of final threshing and separation with a length of no more than 6 intervals between the transverse slats, a single-tier grating is a continuation of the upper tier of the first zone with a bar pitch from 0.5 to 1.5t of the first zone pitch. This solution has practical significance and perspective for implementation by installing them on self-propelled grain harvesters.","PeriodicalId":160902,"journal":{"name":"Traktory i sel'hozmashiny","volume":"111 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":"128093644","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}

Performing monotonous physically difficult operations in agricultural pro-duction leads to the risk of disorders of the musculoskeletal system of workers, therefore, the use of robotic means for physical contact and manipulation with objects in agricultural production is an urgent task that ensures a reduction in the cost of production, an increase in the quality of operations performed and the labor safety of involved specialists. The variability of the physical and geometric characteristics of the fruits and the methods of their collection does not allow the creation of univer-sal robotic grippers, therefore, active research is currently underway on the design of robotic grip-pers for manipulating the fruits of individual crops, differing in weight, density, geometry, surface roughness and other parameters. The article describes the developed conceptual model of robotic gripper control, including the description of the manipulator, gripper, sensor system and the manip-ulated object of agricultural products with various forms, physical and mechanical properties. The article analyzes the physical and mechanical properties of some vegetables and fruits, methods of cutting off the fruit, which should be taken into account when developing robotic grippers. There were discussed a four-stage technique for determining the parameters of robotic gripping, including determining the characteristics of the manipulated object; characteristics of the working environ-ment; determination of the features of the manipulator on which the gripper is planned to be in-stalled, and evaluation of the efficiency of the projected gripper according to a number of criteria. The developed algorithmic model of the choice of configuration parameters for robotic gripping of agricultural products is presented. It provides, based on the analysis of the properties of the manipu-lated object, the development of requirements for the configuration and gripping control system.","PeriodicalId":160902,"journal":{"name":"Traktory i sel'hozmashiny","volume":"20 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":"132439540","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}
