Abstract

The problems of mechanization of collection of coniferous seeds and stocking up cedar nuts aren’t worked enough. One of ways of collection seeds and nuts is an application of mechanism, which transmits a vibration and the percussion impulse to a trunk of a tree. The most important index in collection of seeds from growing trees with the help of this way is a quantity of an acceleration of a crown, which ensures a tearing off cones from branches.

In this work there are theoretical bases of a calculation of a quantity of the percussion impulse, which is enough a tearing off cones.

Key words: the technology of stocking up, the shaker off, the percussion impulse, a vibration, a dynamic quantity
