ATTACHED DISK CULTIVATOR FOR CARE OF FOREST CULTURES (VERSIONS)

摘要

The invention relates to the field of agricultural machinery and in particular, to mechanisms designed to care for forest cultures established planting or sowing to not uprooted glade by loosening and soil preparation disc harrow and for the destruction of weeds, crushing and embedment plant residues predecessor. Attachment disc harrow care forest crops in not uprooted glade, comprising a frame, two pivot sections, each of which comprises a shaft, with a set thereon spherical disks mounted in two bearing supports arranged between the outer and followed by the spherical discs, according to utility model each support is provided with two rolling bearings, the distance h between the inner faces of the outer bearing cages of 0.01 N h 2,5H, where H - the width of the bearing race. In addition, ballast boxes are removable cultivator possibility of mounting and dismounting. The achieved technical result consists in the fact that the increased durability of the bearing supports of the cultivator, as instead supports the sliding bearings on each module drives installed rolling bearing blocks, the presence of the rubber seals sealing eliminates the ingress of moisture and dirt, enhancing the service life. In addition, increasing the durability of the bearings is achieved by reducing the impact load on the bearings, in soil treatment conditions with different number and height of the stumps in the area felled forests, by dismantling the removable ballast weight with drawers beneath it. At the same time, improving the conditions of operation of the cultivator, as it removes the need for regular extrusion bearing grease and regulatory clearances in the bearings during operation, and the use of removable ballast weight eliminates the need for time-consuming manual release crates of ballast weight in the form of sand or stones.
