Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention relates to tillage rollers. The tillage roller includes hollow cylinder 3 mounted on frame 1 equipped with axis 2 with vertical disks 4 mounted on axle 2. On the periphery of vertical disks 4, evenly around the circumference and at an equal distance from axle 2, springs 6 connecting vertical disks 4 are installed axially with the possibility of rotation on bushings 5. Bushings 5 are equipped with sprockets 7 installed outside vertical disk 4, which are engaged with sprocket 8 coaxially fixed on frame 1. The outer edge of springs 6 is made flush with the edge of vertical disks 4.

EFFECT: improved 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 installed axially on the periphery of the vertical disks, evenly around the circumference and at an equal distance from the axis, with the possibility of rotation. The bushings are equipped with sprockets installed outside the vertical disks, which are engaged with a coaxially mounted sprocket stationary on the frame. The outer edge of the springs is made flush with the edge of the vertical disks.

Figure 1 shows a general view of the soil-cultivating roller; Figure 2 shows a side view of the soil-cultivating roller.

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

The tillage roller operates as follows. The axis 2 of the hollow cylinder 3 is connected to the coupling of the tillage unit. When the tillage roller moves, the hollow cylinder 3 with springs 6 installed evenly around the circumference, axially and at an equal distance from the axis 2, connecting the vertical disks 4, rolls over the soil surface. Lumps of soil lying on the surface are destroyed by coils of springs 6. Due to the fact that the bushings are equipped with 4 sprockets 7 installed outside the vertical disks, which are engaged with 1 sprocket 8 coaxially mounted motionless on the frame, it is ensured that the springs 6 rotate at the same frequency, which intensifies the process of crumbling soil lumps due to the rotational movement of the springs 6 and increasing their abrasive effect on the lumps. There is also a reduction in the impact load of the tillage roller on the soil, which contributes to better compaction.

Making the outer edge of the springs 6 at the same level with the edge of the vertical disks 4 also contributes to a smoother entry of the springs 6 into the soil and improves the quality of its compaction across the entire working width of the soil-cultivating roller.
