Description

(54) anti-erosion seam

I

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to anti-erosion plants for subsurface spread sowing, mainly grain crops.

Anti-erosion seals are known that contain openers and are located on an axis with gaps between each other and cone-shaped compacting rollers with cuts on the working surface l.

The disadvantage of these splines is that both the seed sowing of the row and the spacing between them are compacted unevenly as the rollers are installed on one common axis without the possibility of displacement of the rollers relative to it in the longitudinal-vertical plane.

The purpose of the invention is to improve the quality of sowing by increasing the uniformity of compaction of seeded strips and erosion gaps and protrusions.

11e b is achieved by the fact that tapered compacting rollers are installed

between the coulters, and behind each coulter between the cone-shaped rollers, hollow axle rollers, spring-loaded with respect to their axis, are installed; The coyus-shaped working surface is covered with an elastic sheath, which has a hole in the area of the disk cut-out, while hollow shishindric rollers are mounted on the axis by means of movable relative to it sleeves, which are connected to the inner cylindrical surfaces of the rollers, springs are evenly spaced around the circumference, and The rollers have holes, the diameter of which exceeds the diameter of the sleeves, and the elastic shell is made of rubber.

Claims (3)

 FIG. 1 shows the proposed anti-erosion mill, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 1, Seleka contains coulters 1, BOSHP in the form of pointed legs, and a compacting roller located behind them, which is made of a set of disk cone-shaped sealing rollers 2 rigidly mounted on axis 3 and hollow cylindrical rollers 4. Disk cone-shaped rollers 2 are installed on the axis 3 along the track of the intermediates formed by the openers 1, and the cylindrical rollers 4 are mounted behind the openers in the intervals between the rollers 2 along the width of the sowing seeds. The cylindrical rollers 4 are equally spaced around the circumference of the springs 5 attached to the sleeves 6, freely planted on the axis 3. The end walls 7 of the cuts 4 are made in the form of round plates with central diameter 8 and with a diameter exceeding the diameter of the sleeves 5 on 100-150 mm. The working surfaces of the rollers 2 and 4 are covered with an elastic sheath 9 for example rubber. The disk-shaped cone-shaped rollers 2 on the working surface have cutouts 1O, in the zone of which the elastic shell forms an air chamber, which communicates through an opening in the elastic shell with the atmosphere. The cutouts 1O form depressions 11, limited by protrusions (ridges) 12 of the soil. Selka works as follows. Lancet paws of coulters 1 loosen the soil and at the desired depth scatter the seeds in strips. Then the cylindrical rollers 4 compact the grain strips, and the cone-shaped rollers 2 with notches 10 do handicrafts in the inter-spacing of the closed erosion-in recesses 11. In this process, the strips of rows are squeezed from three sides: from above — a cylindrical roller 4, on each side - a horse with a suitable roller 2, which excludes the collapse of the walls and the closing of the recess 11 in the process of rolling. The presence of springs 5 and end walls of rollers 4 with through circular apertures 8 allows them to shift relative to cone-shaped rollers 2 in the longitudinal-vertical plane during operation. Due to the presence of air chambers formed by the openings 1O in the rollers 2 and the elastic sheath 9, in the course of movement between the spaces between the openings 11 are formed of a closed type, limited by protrusions (bridges) 12 of the soil and 914 that have good water retention capacity, since when interacting with With the soil, the rubber sheath 9 of the openings 1O is deformed, compacts the protrusions 12 of the soil, and upon leaving the zone of interaction with the soil, restores the original shape without sticking the notches 10 into the soil. Equal angular distances between the points of attachment of springs 5 to bushings 6 and between the points of attachment of springs 5 to the inner surface of the cylinder of roller 4 allow the latter to exert pressure on the soil equally proportional to their displacement in a plane perpendicular to the axis of the roller at any angle of rotation relative to axis 3 The proposed plant provides a set of favorable conditions both for the germination and development of plants, and for protecting the soil from rain erosion, especially in areas with sufficient and excessive moisture. Favorable conditions for the germination and development of plants are ensured by uniformly compacting the seeded bands across the width of the grasp. The effective protection of soil from storm erosion is achieved by the formation of closed water-retaining grooves with compacted bridges on the seeded field. The result obtained from the new set of essential features is not only higher, but also new, since it is based on an unobvious seal seal due to elastic, jointly movable joints. Claim 1. Antierosion forging, containing coulters and disposed cone-shaped compaction rollers located on an axis with gaps between them, with the aim of improving the quality of sowing by increasing the uniformity of compaction of sowed strips and anti-erosion slots and protrusions, cone-shaped flattening rollers are installed between the openers, and behind each coulter between cone-shaped rollers, empty full cylindrical rollers, and the working surface of the cone-shaped rollers is covered with an elastic sheath, which has an opening in the area of the disk notch. 2. A crop according to claim 1, such that hollow rolling rollers are mounted on an axis by means of sleeves which are movable relative to it, which are connected to the inner cylindrical surfaces of the rollers, evenly spaced around the circumference by springs and the end walls of the empty cylindrical rollers have 916 holes, the diameter of which exceeds the diameter of the sleeves. 3. Cesunca according to claim 1, in connection with the fact that the elastic shell is made of rubber. Sources of information taken into account in the examination 1.
