Design of a cultivator mounted on a tractor with a power of up to 20 kW

Abstract

Cultivators are machines used among others to open and smooth out the surface of the ploughland and to mix mineral fertilizers with soil. The article presents a design of a cultivator mounted on an agricultural tractor with a power of up to 20 kW. The main design assumption mainly focuses on keeping the weight of the device low, while ensuring the required durability. Moreover, the design makes it possible to attach it to the three-point linkage in a category 1 tractor. The drafted design was subjected to the MES analysis, according to which, the maximum travel of the cultivator frame does not exceed 1.3 mm, and the stress typically reaches the level of 40 MPa and does not exceed the stress permissible for the E295 steel. An analysis of the costs of manufacturing the cultivator was also performed and on its basis, it was found that the price should not exceed PLN 1,800.

Research of Methods and Structures of Working Bodies for International Treatment of Amarant

“…Кроме этого, необходимо заметить, что в Европе разработаны роботизированные культиваторы, применяющие оптическое зрение для обхода культурных растений, у таких культиваторов максимально снижена защитная полоса, и она ограничена лишь возможностью подрезать не только сорняк, но и корни возделываемой культуры [12,13]. В настоящее время, данные системы находятся на прототипном уровне и до серийных образцов пока не дошли.…”

Considerations Regarding 3d Modelling and Finite Element Analysis of a Cultivator Type Equipment

“…The One of the requirements for the steady and healthy growth of any people or nation is the abundant supply of food. The ground can be made to produce by properly cultivating the soil and plants suitable for food [1]. Agricultural machinery and installations, together with energy sources, ensure the mechanization of work processes in agriculture.…”

“…The agricultural machine is the work machine used to perform one or more works in the production processes in agriculture, in optimal conditions from an agrotechnical point of view. Agricultural machinery is equipped with various devices, mechanisms and systems to be able to perform certain operations specific to the applied technology [1]. Cultivators fall into the category of agricultural machinery for tillage, along with plows, cutters, diggers, harrows, combine harvesters, soil tillers [1], [4].…”

Analysis of the resistance frame of the equipment for opening and compartmentalizing watering furrows, using 3D finite elements

“…The study, research, and design of load-bearing structures is a field deeply involved in many disciplines of science and technology: civil engineering, [1][2], automobiles, aircraft or water vehicles, medicine, etc. For agricultural machines through load-bearing structures we understand, most of the time, resistance frames [3][4][5][6][7][8][9][10][11][12][13][14]. In general, the works [3][4][5][6][7][8][9][10][11][12][13][14] use 3D finite element analysis for linear-elastic static analysis, implicitly elementary analysis of the strength of structures.…”

There are also works that address the dynamic working regime of assemblies or subassemblies of agricultural machines, problems of modal analysis related to the avoidance of working regimes with resonances, analysis of structural failures using linear and nonlinear analysis, [3].…”
