Abstract

FIELD: agricultural engineering; soil-packing rollers.

SUBSTANCE: frame of soil packing roller-ridge former is made sectional with possibility of changing distance between side beams which are interconnected by adjusting mechanism. Rings are made with diameter decreasing from edges to middle of axle. Springs of equal rate and size are installed on axle between rings. Thanks to it quality of soil cultivation is improved owing to possibility of formation of different sections of ridges depending on requirements of crop.

EFFECT: reduced labor input at servicing of roller.

Description

The invention relates to agricultural machinery, in particular to packer rollers.

Known packer roller comb [1], including a frame, an axis and spherical disks freely mounted on the axis. Between the spherical disks with the possibility of free rotation on the axis and changing the distance between them are rings. Spherical disks are mounted convex to the axis of symmetry of the roller.

The purpose of the invention is to improve the quality of soil cultivation and reduce labor costs for the maintenance of a packer roller comb.

This goal is achieved by the fact that the frame of the compacting roller-comb former is made integral with the possibility of changing the distance between its side beams, which are interconnected by an adjusting mechanism, the rings are made with a decreasing diameter from the edges to the middle of the axis, and springs are installed between the rings on the axis with the same rigidity and size.

In Fig.1 shows a packer roller combing machine, side view, and in Fig.2 - the same top view.

The device comprises a frame consisting of side beams 1 and transverse beams 2. On the side beams 1, an axis 4 is installed through bearings 3. On the axis 4, spherical disks 5 are installed convex to the axis of symmetry of the roller, having the ability to move along axis 4 together with side beams 1 by adjusting mechanism 6. The side beams 1 are fixed in position with respect to the transverse beams 2 with locking bolts 7 inserted into the holes 8. On the axis 4 between the spherical disks 5 there are rings of different diameters 9, which orye freely rotate on the axis 4. Rings 9 are made with a decreasing diameter from outside to the middle axis 4, wherein between the rings 9 on the axis 4 mounted spring 10 with the same dimensions and rigidity.

The compacting roller comb forger also includes a bracket 11, rigidly fixed to the front transverse beam 2, through which the roller is aggregated with the desired machine or mechanism. A rod 13 with holes 14 is pivotally attached to the bracket 11 using a finger 12. The second end of the rod 13 passes through a sleeve 15, pivotally connected by a bolt 16 to the bracket 17. A spring 18 is mounted on the rod 13. To adjust the pressure level of the packer roller the soil is a washer 19, which can be moved along the rod 13, while its position is fixed with a cotter pin 20 in one of the holes 14. To securely fix the rod 13 during operation or transporting the roller on the outer end of the coupling 15, a cotter pin 21.

The compacting roller combing machine operates as follows.

Pre-set the desired profile of the ridge, which is formed using spherical disks 5 and located between them at the same distance from each other rings 9 of different diameters. The distance between the rings 9 is automatically set due to the springs 10 of the same stiffness and size using the adjusting mechanism 6, which changes the distance between the side beams 1.

When the rolling packer roller comb moves along a row onto which a loose soil layer has previously been removed from the row-spacing for seed placement and a soil tubercle has been formed, spherical discs 5 mounted on the convex side inward for more uniform soil compaction roll along with axis 4 and due to the spring pressure 18 form a tubercle, compacting it laterally. At the same time, rings 9 of different diameters located on the axis 4 compact the top of the soil tubercle and finally form a ridge. Due to the pressure of the rings 9 on the soil during their rotation together with the springs 10, the soil lumps are crushed and a loose mulched soil layer is formed on the row surface, which reduces the evaporation of soil moisture.

Improving the quality of soil cultivation is achieved through the formation of various profiles of ridges, depending on technological requirements and the type of cultivated crop. In addition, the implementation of the composite frame, the presence of an adjustment mechanism and the installation between the rings of springs of the same stiffness makes it possible to reduce labor costs for the maintenance of the rolling roller comb.
