The capability for operator protection in case of falling objects accidents is one of the most important criteria for cabin evaluation. For this reason, machines are equipped with falling-object protective structures (FOPS). There is a number of standards defining FOPS requirements depending on the machine class and mass. Engineer’s primary task at FOPS design phase is to develop such a structure...
Aroused in recent time fears for environmental with petroleum compounds, such as polycyclic aromatic hydrocarbons (PAHs) resulted in development of many technological strategies aimed at remediation of degraded and devastated areas. Composting, as ex situ bioremediation strategy can be useful not only in production of natural fertilizers, but also in effective removal of xenobiotics from the environment...
The present paper presents results of research on opinions of farm owners concerning the need and forms of transportation services within the context of their education. According to 59.04% of surveyed farmers, there is demand for transportation services. The primary reason for such demand is time savings (the number of answers increases along with an increase in farmer’s education). 48.80% of farmers...
Contamination of arable lands with hydrocarbon compounds considerably reduces the efficiency and profitability of agricultural production as well as poses a risk of xenobiotics migration into the soil. Therefore, in-depth analyses of biological and physico-chemical phenomena occurring in contaminated soils for the effective prevention of land degradation are crucial. The aim of this study was to evaluate...
This paper presents software supporting management of agricultural holding. Programs supporting farmer activity are divided into two groups: software for current farm management (record and reporting) and for planning and design. The Organizer of Agricultural Technology OTR-7 software is an example of the second group of applications. It enables to design a fleet for farm and to calculate a coefficients...
Nowadays, many methods for compacting straw for energy purposes are known. Compaction of unchopped straw by rolling it with an operating unit consisting of five conical rollers is a new method not used for this purpose so far. Various compaction of briquettes formed by this method takes place by changing the skew angle of the axes of briquetting rollers β relative to the axis of a briquetting chamber...
The aim of the study was to determine the spatial distribution of farm equipment with technical means of production in a given period of time (the period of the agricultural census in 1996, 2002 and 2010) of 20 counties of Lubelskie Voivodeship. The scope of work included the spatial database of the examined region at the level of counties. The data were taken from the European Statistical Office...
The article includes the rules and mechanisms of creating logistics clusters in economy and agriculture. The transport systems and logistic areas were analyzed and their impact on the country’s economic condition and development of its regions was discussed. Considering the perspective economic development of selected region, the clusters' creation stages were determined.
This paper presents selected results of an analysis of damage causes to pellet mill matrix. The tested pellet mill matrix was used for the traditional technological process of pellet production. The tests were carried out since matrix failure times were found out to be too short. In order to assess the causes of matrix damage, tests of chemical composition and hardness of the matrix material were...
The work was made to determine operational costs and cost-effective technologies for preparation of silage from low stalk green fodder, involving baler and various forms of storage systems marked as follows: ASW - wrapping single bales, ZOSZ - wrapping bales on the wrapping serial machine, ZOW - storage bales in a plastic bags using bale charger or collecting chaff in the silo by using pickup trailer...
Organic products undergo biodegradation processes in favourable conditions while being improperly stored. The production of vegetable oils by means of the pressing technology requires high electrical energy input which is converted by friction forces in screw extrusion presses into heat. The heat, in turn, is conducive to the organic mass degradation processes. The purpose of the study was to determine...
The aim of the conducted study was to evaluate to what extent information technologies are used by farmers engaged in fruit-growing production with respect to implementing and maintaining a production system that is compliant with the GLOBAL G.A.P. standards. The study covered 71 farms associated in five producer groups. The study was conducted in Łódzkie and Mazowieckie provinces. Commercial farms...
The paper presents results of study of the pellets made of agricultural biomass. In the tests wheat straw was used and then ground raw materials were concentrated using two types of pelleting machines: with flat matrix and driven by compacting rollers as well as with ring matrix. The research methodology consisted of measurements of physicochemical properties of pellets, i.e. humidity after compaction,...
The volumes of wastes produced at selected farms and the manner of their management are subject to analysis in this study. The wastes from plastics have been divided into four basic groups depending on their type. The volumes and the assortment of wasted from plastics formed at the time of agrarian production in the period of 3 years have been analysed. On the basis of the performed studies, the volumes...
In the Polish agriculture, farm vehicles, machines and devices with a varied complexity and modernity of structural solutions are used - from simple (harrow, plough) to very modern (combine harvester, beetroot harvester, tractor, sprayer). A considerable complexity of processes, mechanisms and phenomena, which take place during their operation and considerable wear and age in the light of stricter...
The article presents the process of designing and strength analysis of the body and continuous track unit of a specialised track-laying vehicle for the transport of biomass obtained on wetlands performed within framework of the development project No. PBS2/B8/11/2013 “Autonomous technology for the transport of biomass obtained on protected wetlands” related to the removal of unwanted vegetation from...
The article presents the problem of assessment of the degree of operator training for modern parallel driving system, used in a precision agriculture. The training was conducted for ten potential operators and their skills were rated subjectively after determined number of experimental runs. Data containing information about individual journeys were collected during the training. Then the trajectory...
The article describes the problem of stress analysis in spray sterilizers according to EN 13445-3, widely used in the food industry. Operating conditions of the test device were characterized and a method of design verification using FEM was defined. Conditions of computer implementation research were determined and choice of a methods for assessing sterilizer was made, based on stress analysis. It...
The main aim of the experiment was to determine in the laboratory conditions forces acting on the hoe coulter. The measurements were carried out on an abrasive test unit type "rotating bowl" unit using designed and built measuring system. The velocity of the coulter was in the range of 1,11 to 2,22 m·s-1, and the depth of penetration into the river sand was 40 or 60 mm. On the basis of the...
