INSTRUMENT FOR INVESTIGATING CENTRIFUGES OF BULK MATERIAL SPREADING UNITS Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: instrument is made in the form of hollow ring 1 with partitions 2 fixed inside hollow ring in position deflected from radial orientation. Partitions 2 define cells 4 in ring 1. Discharge tray 5 is positioned under each cell 4. Rear wall 6 of instrument is made in the form of truncated cone with wider lower base. Plate 8 is fixed in cantilevered relation to upper edge 7 of tray 5 above its front part. Stabilizer 9 is fixed to upper part of each cell 4 and positioned in middle part of each cell so that it covers the entire section thereof. Stabilizer is made in the form of set of tape of strong flexible material. Instrument is used for investigating centrifuges of units for spreading bulk materials, in particular, mineral fertilizers. EFFECT: reduced errors in measurements effectuated by means of said tool used for investigating distribution of bulk materials by spreading angle. 2 dwg
