Abstract

The utility model relates to the field of agricultural engineering and is intended for tillage. The skating rink includes a frame, spherical disks mounted on axles, axles mounted on vertical shafts, shafts pivotally mounted on the frame to rotate in a horizontal plane, for symmetrical rotation of both disks on the shafts, multidirectional levers are connected by a link. Spherical disks perform the function of raking the soil and compaction of the lateral surface of the ridge. The sealing of the central part of the ridge is carried out by a rolling roller mounted between spherical disks, having the ability to move and fix in horizontal and vertical planes. The soil compaction in the ridge is controlled by means of a spring, one end of which is connected to the rod, and the other through the tension bolt to the frame. The volume of soil raked by spherical disks depends on the angle of their installation. During operation, the installation angle of the spherical discs varies depending on the variation in the pressure exerted by the soil on the convex surface of the discs. Thus, the roller adjusts the degree of compression of the soil in the ridge to obtain a more uniform compaction. Such a constructive implementation will improve the uniformity of seed germination due to the alignment of the seal of the ridge along its entire length. 2 ill.

No. 20], including a frame, an axis, and spherical disks mounted on half shafts with the possibility of their movement in a vertical plane and fixing in a predetermined position, the roller frame being made integral with the possibility of changing the installation angle of the side beams together with spherical disks to the direction of movement and fixing in a predetermined position, between the spherical disks along the axis of symmetry of the roller, a press disk is installed with the possibility of free rotation with a ring mounted on its outer edge, around the circumference of the press ska holes are made at an equal distance from its outer edge with the same angular pitch, in which spring-loaded elastic rods are mounted with the possibility of moving in the radial direction of the press disk, and the press disk is installed with the possibility of changing its position together with the axis in the horizontal plane and fixing in the required position .

A disadvantage of the known device is the inability to vary the force exerted by the roller on the ridge, depending on changing soil conditions (moisture, density), which will lead to uneven compaction of the ridge along the length and negatively affect the uniformity of seed germination.

Disclosure of invention

The purpose of the utility model is to improve the quality of the formation of the soil ridge, the conditions of germination and development of seeds.

This is achieved by the fact that, in contrast to the known technical solution, spherical disks are mounted on the axles, the axles are mounted on vertical shafts, the shafts are pivotally mounted on the frame, thus the spherical disks have the possibility of symmetrical rotation in the horizontal plane, for the symmetrical rotation of both disks on the shafts are fixed multidirectional levers connected by a traction, changing the degree of compaction of the soil is carried out by a spring, one end of which is connected to the traction, and the second through a tension bolt - to the frame, such design allows the disk to modify the setting angle depending on soil conditions, central ridge seal between the spherical disc carries a smooth press roller having a possibility of displacement and fixation in the horizontal and vertical planes. Thus, in the process of movement, the soil in different areas exerts different pressure on the convex surface of the spherical disks, forcing them to change the angle of attack, thereby changing the volume of soil supplied to the compression zone of the smooth rolling roller, which leads to a change in the compression ratio of the ridge and more uniform compaction regardless of constantly changing soil conditions.

The implementation of the invention

The device comprises a welded frame consisting of longitudinal (1) and transverse beams (2). Housings (3) are mounted on the longitudinal beams (1) with bolts with angular contact bearings pressed into them, shafts (4) are installed in the bearings, axes (5) are fixed at their lower ends. Hubs (6) with spherical disks fixed on them (7) are mounted on the axes. Spherical disks are set convex to the axis of symmetry of the roller and have the ability to change the angle relative to the direction of movement (angle of attack) by rotation together with the shaft (4), to symmetrically change the angle of direction of movement of both disks on the upper ends of the shafts, levers (8) are fixed, which through the swivel joint transmit the force created by the disks during movement to the traction (9). The central part of the ridge is sealed by a press roller (10) mounted on the frame by installing a leash (11) in the bracket (12), which allows fixing the position of the roller in the vertical and horizontal planes using bolts (13, 14). The angle in the direction of movement of the spherical disks during operation is regulated by a spring (15), one end of which is fixed to the rod and the other through the adjusting bolt (16) to the cross beam, the rotation angle is limited by adjusting bolts (17, 18) located on a plate (19) mounted on a longitudinal beam. The roller is aggregated with the required machine using the brackets (20).

The profile-forming roller operates as follows: first, using the adjusting bolts (17, 18), the limits are established within which the angle of attack of the spherical discs can be changed depending on the soil conditions, and the tension spring (15) is set with the tension bolt (16) to create the optimal soil density. Then, using the adjusting bolt (13), the press roller (10) is fixed in a vertical plane so as to obtain the desired height of the ridge. The press roller (10) is fixed in the horizontal plane by a bolt (14), which allows for a better ridge seal.

When a profile-forming roller moves along pre-treated soil, spherical disks (7) mounted on the convex side to the axis of symmetry of the roller, rolling, simultaneously raking the soil into the ridge and compacting it from the sides. A rolling roller (10), freely rotating on the axis, seals the central part of the ridge in the seed zone. Since the soil conditions even within the same area can vary significantly, to create the optimal density along the entire length of the ridge, it becomes necessary to vary the pressure of the roller on the soil. The pressure varies at a specific point due to the fact that the soil, when the roller moves, puts pressure on the convex surface of the spherical disks (7), the magnitude of this pressure depends on the soil conditions (moisture, density), so the angle of attack of the disks will change due to their rotation together with the shaft (4) and stretching the spring (15) using levers (8) and traction (9). As a result of this, a soil ridge is formed with an optimal density in its central part in the seed location zone, this speeds up the process of seed germination and contributes to an increase in the yield of cultivated crops.
