Seed distributor with attachment frame - has setting shaft pivoted to achieve height adjustment relative to support wheel

摘要

The device has an attachment frame with a depositing device, which is guided via a linkage, such as two parallelogram linkages, and a support wheel. A broacher is fitted to a boom arm and can be adjusted relative to the support wheel via a first height adjuster. A second height adjuster fixes the position of the support wheel relative to the seed laying device. There is a linkage between the support wheel and the seed layer and a vertical setting shaft with which the boom arm is connected with a fixing device at its top end. The setting shaft (13) can be pivoted by a sufficient amt. to achieve the first height adjustment (13, 14) of the furrow blade (15) with respect to the support wheel (12).
