<p>#CMT# #/CMT# The seeder (1) has a variable width telescopic frame (2) including two carrier wheels (3), sower elements (4) that are divided in a regular and adjustable manner on the frame, and stoneburiers (5) associated with the sower elements. Each sower element defines a sowing row (10), which coincides with a median vertical plane of the corresponding sower element, where distance between two close sowing rows defines a spacing. Each wheel comprises twin wheels (12, 13) that are spaced relative to each other and are placed on sides of the sowing row. #CMT#USE : #/CMT# Precision seeder for distributing seeds on a sowing line with constant spacings. #CMT#ADVANTAGE : #/CMT# The seeder can carry out sowings in tightened rows without packing the sowing rows or degrading one of parts of the seeder by making adjustment range for the spacing to be wide while ensuring provision of the twin wheels between the sowing rows irrespective of adjustment of the spacing in an effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top sectional view of a precision seeder in a tightened row configuration. 1 : Precision seeder 2 : Variable width telescopic frame 3 : Carrier wheels 4 : Sower elements 5 : Stoneburiers 10 : Sowing row 12, 13 : Twin wheels.</p> |
