    Efficiency of intervention technologies for snow removal equipment on public roads

    Trans Motauto World, Vol. 7 (2022), Issue 3, pg(s) 120-121

    The activity of snow removal on public roads is of particular importance for ensuring road transport in winter and implicitly for maintaining a stable, predictable and efficient economic and social climate. The organization of road snow removal is usually done by the local public authorities, through the public road administrator, varying depending on the geographical and climatic location of the road site. In Romania, the snow removal activity is regulated by the “Regulation on preventing and combating snow on public roads”, indicative AND 525-2013, developed by the National Company of National Highways and National Roads in Romania. The snow removal activity is usually performed on the basis of a service contract and is temporary, depending on the evolution of meteorological phenomena and climatic zones.
    The actions to prevent and combat the consequences of dangerous meteorological phenomena are carried out according to their intensity on the following phases, as follows: prevention of icing formation and its neutralization, spreading of anti-skid material and snow removal. The preventive spreading of the anti-skid material is recommended to be done first on the entry / exit arteries in / from the localities. The activity of mechanical cleaning of public roads (streets, bridges, alleys, roundabouts) of snow with blade machines is performed when the snow layer exceeds the thickness of 5 cm. The activity is carried out by successive passages, starting from the axis of the road to the curb, until the complete removal of the snow layer.

    Problems of production and use of hydroponic products in agricultural production

    Mechanization in agriculture & Conserving of the resources, Vol. 65 (2019), Issue 2, pg(s) 72-73

    Production of hydroponic green fodder is an important task of agriculture, which in developed countries is given enough attention. Currently, the world’s developed a considerable number of various designs installations for the production of hydroponic products, but the main working body of these installations are trays in which the cultivation of hydroponic green fodder, as one of the most simple, but fairly effective devices for seeding, cultivation and the ready products. The main global trends in the production of hydroponic green fodder, as one of the components of the diet of poultry and cattle, are considered. The paper analyzes the operation of the workshops for the production of hydroponic products equipped with the facilities of the new design developed by us. Compared some economic characteristics of hydroponic workshops manufactured in foreign countries and developed in Ukraine. Thus, the conclusion is obvious – domestic plants for the production of hydroponic green fodder are more economical than their foreign counterparts.

  • MECHANIZATION IN AGRICULTURE

    EXPERIMENTAL STUDY OF OPERATION INDICATORS OF BEET TOPS HARVESTING MACHINE FOR SUGAR BEET TOPS CONTINUOUS CUTTING

    Mechanization in agriculture & Conserving of the resources, Vol. 64 (2018), Issue 2, pg(s) 39-41

    Field experimental studies of a new beet tops harvesting machine, which is front mounted on a wheeled tractor aggregating tractor, are carried out, carrying out a continuous non-sensing cut of the green massif of sugar beet tops. At the same time, a new laboratory-field installation was developed, which consists of a rotor type front mounted rotary type machine with a horizontal axis of rotation, a transverse screw for collecting the cutted leaves from all width, and a loading mechanism in the form of a paddlewheel and a loading nozzle. During the field experiments, the tractor moving with a specified speed regime fixed by track measuring wheel, the total cutting height was set in a predetermined interval by means of two pneumatic sensing wheels with adjustment mechanisms. The rotational speed of the rotary cutter, with arched knives mounted on the drive horizontal drum, was varied with the help of replacement asterisks. In the prepared area of sugar beet field, the beet tops was cut at various parameters of the harvesting process, which was then estimated by the size of the remaining tops remnants left on root crops heads and in the aisles. According to the developed program and methodology, statistical processing of the results of experimental studies with the help of a personal computer was subsequently carried out, which allowed obtaining graphical dependencies of the indicated tops residues on the root crops heads, which made it possible to establish performance of new harvesting machine for continuous cutting of sugar beet tops. The established dependencies made it possible to choose rational constructive and technological parameters for harvesting tops by front mounted harvesting machine.

  • MULTI-FUNCTION DEVICE OF A CANAL CLEANER FOR PERFORMING A COMPLETE CLEANING OF DRAINAGE CANALS

    Mechanization in agriculture & Conserving of the resources, Vol. 61 (2015), Issue 3, pg(s) 15-0

    We offer a multi-functional operating element of rotary type for a channel cleaner, which is capable of performing the entire cycle of cleaning household water reservoirs (ponds), in particular:1. due to the compound rotor:1.1. mow and chop the crop;
    2. due to the implementation of detachable body:2.1. mill and transport “dry” soils using a jet of air;2.2. pump water;2.3. extract and transport the soil from under the water;

    3. due to the installation of the teeth on the lower movable part of the body:3.1. work as a clamp grapple to remove garbage from water reservoirs (ponds).

    The basis of multifunctionality of this invention is in the principle of implementation of the maximum number of hidden abilities of the initial technical system, its rotor, framing, manipulator parts, which implies the subsequent creation of a reclamation robot.
