Abstract

Изобретение относитс к сельскохоз йственной технике, в частности к дисковым почвообрабатывающим оруди м. Цель изобретени - повышение срока службы оруди путем исключени циклического колебани силы сопротивлени почвы за счет устранени самопроизвольного выстраивани зубьев вырезных дисков в р д. Устройство содержит ось 1, на которой группами смонтированы вырезные диски 2 с восемью зубь ми, а диски 3 имеют шесть зубьев. Количество групп на оси 1 размещено не менее трех. Число дисков в группе должно быть меньше или равно единице. При движении оруди по обрабатываемому участку диски 2 и 3 заглубл ютс и производ т обработку почвы при исключении самопроизвольного выстраивани зубьев в один р д. 3 ил.The invention relates to an agricultural technique, in particular to disc soil-cultivating tools. The purpose of the invention is to increase the service life of a tool by eliminating cyclic fluctuations of the soil resistance force by eliminating spontaneous alignment of the cut-out disk teeth in a row. The device contains axis 1, on which groups are mounted cut disks 2 with eight teeth, and disks 3 have six teeth. The number of groups on axis 1 posted at least three. The number of disks in a group must be less than or equal to one. When the guns move along the area to be treated, the disks 2 and 3 are deepened and the soil is treated with the exclusion of spontaneous alignment of the teeth in one row. 3 sludge.

Claims

Claim

A disc harrow, including a frame and disks with teeth freely mounted on the axis, separated by spacer bushes, characterized in that, in order to increase its service life by eliminating cyclic fluctuations in the soil resistance force by eliminating spontaneous alignment of the teeth of the cut-out disks in a row, disks on the axis are arranged in groups, with the number of disks in the group being greater than or equal to one, and the number of teeth in the disks in the subsequent group is determined from the relation where n _L0СЛ is the number of teeth in the disks in the subsequent group;

ⁿ nf> ea is the number of teeth of the disks in the previous ³ group, while the number of groups on the axis is not less than three, and the difference between the number of disks in the groups is less than or equal to one.
