Abstract:Hlevi za prosto rejo krav molznic imajo na tleh položene rešetke, ki bi naj zagotavljale samodejno čiščenje blata. V mnogih hlevih blato ostaja na rešetkah, zato je tla vseeno potrebno dnevno čistiti. V diplomski nalogi smo preizkušali vpliv naklona čistilne deske na čistočo tal s pomočjo lastno izdelane naprave za čiščenje rešetk. Čistilna deska je široka 50 cm in visoka 20 cm. Narejena je iz 3 mm debele kovinske plošče in ima na spodnjem robu 1 cm debelo gumo, ki preprečuje obrabo rešetk. Za spreminjanje naklona smo na desko privarili gibljive člene. Potrebno silo za čiščenje smo izračunali s pomočjo merilnika pospeškov. Poskus je bil zasnovan pri treh naklonih deske (60 0, 90 0 in 120 0) v treh ponovitvah tako, da smo hodnik razdelili na tri polja, velikosti 14,6 m2 (2 m x 7,3 m). V raziskavi smo ugotovili, da so pri čiščenju gnoja iz rešetk sile v smeri osi x odvisne od naklona deske; najmanjša izmerjena sila 29,23 N je bila pri kotu 60 0 in največja pri 120 0 (31,12 N). V smeri osi y so bile sile tudi značilno odvisne od naklona deske. Pri kotu 120 0 voziček bolj zanaša levo ali desno, zato je izmerjena sila večja (40,95 N) kot pri kotu 60 0 (38,23 N). V smeri osi z je bila velikost izmerjenih sil bolj odvisna od višine rež na rešetkah kot od naklona deske, saj je voziček pri vseh kotih enakomerno poskakoval, zato so bile velikosti sil enake.

Title:The Influence of the Cleaning Board Inclination on the Cleanliness of Floor Grids in a Cowshed
Abstract:Cowsheds for free range dairy cattle have floor grids, which are to provide automatic cleaning of the mud. In numerous cowsheds the mud stays on the grid and the floor still needs daily cleaning. In this diploma paper we tested the influence of a cleaning board inclination, using a self-made cleaning device. The cleaning board is 50 cm wide and 20 cm high. It is made of a 3 mm thick steel plate and has a 1 cm thick rubber at the bottom edge to prevent wearing down. To change the inclination, flexible links, which allow changes of the inclination, were attached to the board. The required cleaning force was calculated using the accelerometer. The experiment was based on three inclinations of the board (60 0, 90 0 and 120 0) in three repetitions so that we divided the corridor into three fields in the size of 14.6 m2 (2 m x 7.3 m). It was found that in cleaning of the manure from the grid, the forces in the direction of the x-axis depend on the inclination of the board; the smallest measured force was 29.23 N at an angle of 60 0 and the maximum at 120 0 (31.12 N). In the direction of the y-axis the forces were also characteristically dependant of the inclination of the board. At an angle of 120 0 the trolley skids left or right, so the measured force is higher (40.95 N) than at the angle of 60 0 (38.23 N). In the direction of the z-axis, the size of the measured force depended on the height of slots on the grid rather than on the inclination of the board, as the trolley bounced evenly at all angles and therefore the force sizes were the same.
