DEVICE FOR SOWING WITH ACCESSORY FOR FERTILISER APPLICATION INSTALLED ON FRONT SHAFT Russian patent published in 2010 - IPC A01B49/06 A01C7/06 A01B63/32 

FIELD: agriculture.

SUBSTANCE: combined device, which is intended for forward motion on earth comprises truss, having front element of truss and transversely arranged shaft, which is joined to front element of truss with the possibility of rotation. Along shaft, at a certain distance from each other, there are accessories arranged for application of fertilisers to soil. Behind accessories for application of fertilisers to soil there are accessories mounted on truss for application of materials intended for interaction with soil. Truss has lifting structure, intended for its lifting and lowering versus earth for variation of working height of accessories installed on truss. Shaft has facilities for its rotation in order to vary working height of accessories for application of fertilisers. Shaft is fixed to truss with the possibility of its rotation by means of bearing unit joined to bearing support. Bearing support is arranged with the possibility of adjustment along vertical line for selective fixation of shaft in one of multiple vertically arranged areas and for variation of working range of heights of accessories for application of fertilisers. Combined device for application of fertilisers and planting, designed for forward motion on earth, is arranged as similar to combined device designed for forward motion on earth with the following difference - accessories for application of materials are arranged as of tail type, accessories for application of fertilisers are arranged as of disk type, and facility of shaft rotation is arranged in the form of motor. Shaft and truss are joined to bearing structure, which may be displaced to adjust vertical position of shaft versus truss. Device designed for forward motion on earth has design similar to design of combined device designed for forward motion on earth with the following difference - accessories for application of fertilisers are replaced with accessories attached to truss for performance of works on earth. Structure for shaft adjustment is connected to truss and shaft for lifting and lowering of shaft versus truss for maintenance of permanent angular location between accessories for application of materials and earth as range of working frequencies is changed.

EFFECT: above-specified devices make it possible to use wide range of truss heights at various heights of accessories.
