Abstract
The industrial demand for raspberry harvesters is high again. The article presents domestic and foreign experience in the development and improvement of raspberry harvester catchers. The authors note the pre-dominance of non-driven plateand disk-type catchers. They list some advantages of the catcher with the arrangement of each section disks on the longitudinal beam hinged to the harvester frame in its upper part. The gravitation moment of the catcher sections arising as a result of this design solution forcibly compresses the raspberry row to an acceptable width. To obtain the information necessary for further improvement of the design, the authors studied the raspberry stem stand of the Balsam variety. As a result, they obtained a regression model of the relationship between the transverse force acting on the stem necessary for the raspberry row formation, its diameter and the required transverse limb. The pairwise correlation coeffi cient (0.617) indicates a dominant infl uence of raspberry stem diameter on the transverse force. They also determined the value of the moment of gravity of the catcher sections that is adapted to the optimal row density and equals 1085 N·m. The determined parameters are readily adjustable.
