Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention relates to tillage rollers. The tillage roller represents a hollow cylinder mounted on a frame and equipped with axle with vertical discs mounted on axle. Along the periphery of vertical discs, springs connecting vertical discs are mounted axially at an equal distance from axle uniformly along the circumference. The outer edge of the springs is made flush with the edge of the vertical discs. Additional springs are installed inside the springs and adapted for rotation on the bushings. The bushings are installed in vertical discs and are equipped with sprockets mounted outside the vertical discs, which are engaged with a sprocket coaxially mounted fixedly on the frame.

EFFECT: invention improves the quality of soil compaction and crumbling of soil clods.

Description

The invention relates to agricultural engineering, in particular, to soil cultivating rollers.

A known soil-cultivating roller [Tilling roller // RF Patent No. 121418. - Publ. 10/27/2012, Bulletin. No. 30], including a hollow cylinder with ribs evenly spaced around the circumference. The ribs are installed along a helical line connecting the vertical disks. Inside the hollow cylinder there is a smooth cylinder, the diameter of which is less than the radius of the hollow cylinder. The smooth cylinder is equipped with an axis mounted in bearings on leads on the axis of the hollow cylinder.

The disadvantage of the tillage roller is the insufficient quality of soil compaction and crumbling of soil lumps.

The technical result is improved quality of soil compaction and crumbling of soil lumps.

The technical result is achieved by the fact that on the periphery of the vertical disks, springs connecting the vertical disks are axially installed evenly around the circumference and at an equal distance from the axis. The outer edge of the springs is made flush with the edge of the vertical disks. Additional springs are installed inside the springs with the possibility of rotation on bushings. The bushings are installed in vertical discs. The bushings are equipped with sprockets installed outside the vertical disks, which are engaged with a coaxially mounted sprocket stationary on the frame.

In fig. 1 shows a general view of the soil-cultivating roller; Fig. 2 - the same, side view.

The tillage roller is a hollow cylinder mounted on a frame 1 equipped with an axis 2 with vertical disks 3 mounted on the axis 2. On the periphery of the vertical disks 3, connecting vertical disks 3 springs 4 are axially installed evenly around the circumference and at an equal distance from the axis. The outer edge of the springs 4 is made at the same level with the edge of the vertical disks 3. Inside the springs 4, additional springs 6 are installed with the possibility of rotation on the bushings 5. The bushings 5 are equipped with 3 sprockets 7 installed outside the vertical discs. The sprockets 7 are engaged with a coaxially mounted sprocket 8 fixedly mounted on the frame 1 .

The tillage roller operates as follows. Axle 2 is connected to the coupling of the tillage unit. When the tillage roller moves, a hollow cylinder with springs 4 installed evenly around the circumference, axially and at an equal distance from the axis 2, connecting the vertical disks 3, rolls over the soil surface. Lumps of soil lying on the surface are destroyed by coils of springs 4. Making the outer edge of the springs 4 at the same level with the edge of the vertical disks 3 also contributes to a smoother entry of the springs 4 into the soil and improves the quality of its compaction across the entire working width of the tillage roller.

Due to the fact that the bushings 5 are equipped with 3 sprockets 7 installed outside the vertical disks, which are engaged with a coaxially mounted sprocket 8 stationary on the frame 1, when the soil cultivating roller moves, additional springs 6 rotate at the same frequency. In this case, lumps of soil falling into the internal space of the springs 4 are pinched between their turns and the turns of additional springs 6. Due to the rotation of additional springs 6, these lumps of soil are destroyed by shear stress and abrasion. This promotes better destruction of lumps and intensifies the process of crumbling soil lumps due to the rotation of additional springs 6 and increasing their abrasive effect on the lumps.
