Description

one

The invention relates to agricultural machinery,

A known combination tillage machine, including a rotary chopper, designed to cut pineapple plant residues l. However, in this machine, a shredder design is provided for cutting off the leaves of the underground part of the stubble residues of pineapples and is not at all suitable for cutting crop stalks of corn and other plants.

It is also known the combined tillage implement, which includes with the support Konecafvffl and installed on it successively a flat-cutting tool and a bar with a drive mechanism {2

The disadvantage of this tool is that crop residues are not crushed, and layer-by-layer soil tillage is poorly performed.

The chain of the invention is to increase the quality of layer-by-layer tillage with simultaneous shredding of the stubs of the steep grain crops.

In order to achieve this, in a combined soil-cultivating tool on the field in front of and above the flat-cutting working body, a spring-loaded stem straightener is installed, made in the form of a vertical rotation shaft with water-resistant cutting discs on it with successive reduction of their diameters downwards.

FIG. 1 shows schematically a combined tillage implement, side view; in fig. 2 — node 1 in FIG. one.

On the frame 1 with the supporting wheels 2 and the adjusting mechanisms 3 of the total depth of loosening, the stem rods 4, the cutting blade working body j 5 and the rod 6 are forcibly rotated.

Each stem splitter 4, fixed on frame 1, at a distance from each other equal to the adopted width between the coarse crops, consists of a casing 7 mounted on a vertical shaft 8,

To each casing 7, cutting disks 9j 10 and 11 of various diameters of the rotor are radially located in several rus. with a consistent decrease in their downward. Through the casing 7 of each stem 4, the lower rus of the cutting discs are constantly pressed to the bottom of the furrow | by a spring 12 installed between the casing 7 and the restrictive washer 13, which allows the 4 microscopes i of the microtravel to be copied across the width of the combi tool.

Shaft 8 of each stemblade 4 and rod 6 receive rotation from the drive

14, for example a hydraulic motor, through a system of sprockets 15, 16, a camshaft 17 and bevel gears 18.

Shaft 8 of each stem strap 4 is mounted. On frame 1 in bearings 19,

Separate parts of the camshaft 17 are interconnected by safety clutches 20, which can be triggered by possible overloads in the drive circuit 14 of the working members 5. The implement is hung on the tractor by means of a link 21.

The work of the combined gun is as follows

In the process of translational movement of the gun, the stem-blasting machine 4, the plane-cutting tool body 5 and the rod 6 are deepened to the loosening depth previously established by lifting the support bar 2 with the adjustment mechanisms 3 by a predetermined value.

The drive mechanism 14 provides rotation of the windrowers 4 and the rod 6 while simultaneously moving them along with the tractor, with which the rigging tool.

Due to the fact that the rotational moment of rotation of the cutting discs of the upper russes of growers 4 is much larger than the stripping moment of the lower rushes, preliminary crushing of the stems, such as maize (to the roots), subsequent cutting of the roots and loosening of the soil in rows of passage of stem strippers 4 without spraying and vertical mixing .

Located behind the stemmedi mi

4 and below the root system of large-stalk crops, flat-cutting working bodies

5 make it possible to carry out continuous irresistible loosening of the aisles, as well as cutting deeply rooted yushchi weeds.

The rod 6, rotating in the upper tier, previously well loosened by the stalk boring machines 4 and the flat cutting unit 6, aligns the floor surface, cuts weeds with a shallow root system and compacts the lower soil horizons, creating the required compacted bottom of the seed bed.
