FIELD OF THE INVENTION The invention relates to agricultural machinery and is an improvement of the device according to star. N 1417804.

The purpose of the invention is the expansion of technological capabilities by ensuring the quality of processing of various soils.

Figure 1 shows a rotary tillage tool, side view; figure 2 - the bottom of the harrow, a longitudinal profile.

The rotary tillage implement contains frame 1 with 2 additional ig disks and 3 main needle disks 4 installed in succession on horizontal axes. The batteries of disks 3 and 4 are interconnected by means of chain transmissions 5 and 6. On axis 2, batteries of the main disks 4 are installed replaceable sprocket 7, having fewer teeth than sprockets, fired on the axes 2 batteries of additional disks 3. Stars of batteries of the first and subsequent rows of additional disks 3 have the same number of teeth, those. The disks 3 rotate with the same deceleration relative to the disks of the 4 guns.

The axes 2 of the batteries of the first and second rows of additional disks 3 are spaced apart from each other.

where R is the radius of the circle of rotation of the socks of the needles of the disks 3;

k is the settable rate of deceleration rate of the disks 3;

m is the number of rows of additional disks 3;

Z - the number of needles on the disks;

1-1,2, W ... P - integer.

Additional disks 3 of each subsequent battery are installed with the needles displaced in the plane of rotation relative to the needles of additional disks 3 of the previous battery.

The specific value of the angular displacement of the needles of the subsequent discs 3 relative to the position of the needles of the previous discs 3 is calculated depending on the magnitude of the gear ratio of the chain transmission 6 between the axes 2 of the main discs 4 and the additional discs 3, the number of needles on the disc 3 and the number of rows (batteries) of additional discs 3,

The tool works as follows.

When moving the assembly, the battery of the main discs 4 rolls over the soil and, through chain transmission 6, report the rotation of the first row of additional discs 3 slowed down relative to the discs 4. The subsequent rows of additional disc batteries 3 rotate at the same speed as the first row of discs 3 . Needles drives 3 first p yes

when passing through the soil, they form ridges of height H at the bottom of the furrow. In order to reduce the height of the ridges at the bottom of the furrow to the minimum value of h, it is necessary to install additional disks 3 second

row with the displacement of their needles relative to additional disks 3 of the first row in the plane of rotation in one direction or another.

The calculation of the angular displacement of the needles on the discs is based on the constant distance I between the axes 2 of consecutively located batteries of the discs 3, i.e. compensation of the new distance H between the axes of 2 additional disks 3, which would have to be installed when using an asterisk 7 with a different number of teeth to maintain the minimum height h of the ridges at the bottom of the furrow instead of their maximum height H, which would occur if the needles of the disks 3 adjacent rows were not shifted relative to each other.

For example, with R 275 mm, k 5, m 2, distance (720 mm. To work on wet soils, in order to avoid clogging of discs with crop residues, it is advisable to reduce the speed of rotation of additional discs, for example, up to, and install second discs with offset their needles at an angle of p 20 ° with respect to the disks 3 of the first
