Description

one

This invention relates to an agricultural machine industry.

Lime tillage cutters, including a milling drum with working bodies attached to it and a protective cover with supporting runners.

However, the known tillage cutters can not cut the roots of weeds and do not provide a stable depth of tillage. When meeting with the roots of weedy plants, the milling tool is deepened, and its working parts (knives) often break.

The purpose of the invention is to trim the roots of weeds and stabilize the depth of the soil.

For this purpose, disc-shaped undercutting knives are installed at the sides of the milling drum and coaxially with it. The latter have a larger diameter than the milling drum, and are equipped with a drive that ensures the rotation of the trimming knives in the direction opposite to the rotation of the milling drum.

The drawing shows schematically the proposed tillage cutter in two projections.

The tillage cutter consists of a milling drum 1 with shaft 2, on each side

which and coaxially with him installed disc blades 3 with a shear plate 4. Moreover, the diameter of the disc blades is larger than the diameter of the milling drum. The cutter drive includes a safety coupling 5 with a drive shaft 6, a central bevel gear 7 and two side gears 8 and 9. At the same time, the intermediate shaft 10 of the side gear 9 is connected to the shaft 2 by a chain transmission 11. The soil tillage cutter is also equipped with a protective casing 12 and support slides 13 The milling cutter is attached to the tractor with the help of t g 14.

During the forward movement of the tillage cutter, the rotation from the tractor's PTO shaft through the cardan shaft, the central bevel gearbox and the side gearboxes are transmitted to the undercutting disc blades,

and on the shaft of the milling drum - from the side of the side reducer weeded through the chain drive ..

With this drive scheme, the milling drum and undercutting knives receive opposite directions of rotation. The main soil milling is performed by a milling drum. At the same time, the disc blades cut the roots when forming grooves on the sides of the treated strip.

When meeting with the roots of weed vegetation, the milling drum under the action of the reaction force of the night stpe: itc Byg; If the direction of rotation of the cutting knives is opposite to the rotation of the milling drum, then there is a deepening force from the night reaction, which prevents the milling of the milling drum. This ensures that the depth of processing and the soil is reduced to a minimum. At the same time, the undercutting knives in combination with the counter-ripping: with thicker plates, the roots are cut in two places, which makes it easier for them to remove the milling drum from the night.

PRESENTATION OF THE TREATMENT AND TILLAGE MILLING MACHINE, INCLUDING THE MILLING DRUM WITH THE WORKED APPARATURES, ENTREATED, AND THE PROTECTIVE CASE WITH ONORPHEMN COLOSIS FROM THEIR , from a year, the cutting of the roots of weeds and plants and plants - - the depth of processing and the soil, but on the sides of the frezfnogo drum and coaxially with it: 1: the donkey is crushed. In this way, the nizhelennye have a larger diameter, φ) ezer1; th drum, and cn;: keni irivodoi and ensuring rotation of the cutting knives in the direction opposite to the rotation of the milling drum.
