Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The aim of the invention is to improve the quality of the leveling of the soil. The tool consists of leveling and sealing plates fixed to the frame. The leveling plate has fastened working bodies (PPO) fixed on it by means of a vertical joint 20 and spring-loaded spring 11. Each of the PPOs is made in the form of a stand 9 with a horizontal knife 10. The stand 9 is made in the form of a cone and installed at an acute angle to the direction of movement. PPO is attached to the sealing plate. When the guns are moving, the leveling plate cuts off irregularities and falls asleep cavities. Racks 9 PPO due to its shape and installation contribute to a better backfilling of the soil cavities. The sealing plate of the switchyard with PPO compresses the soil and creates a mulch layer. 3 il. HanpaS / ieHue / p KO / ieffa / Lfu Punch dbtzheffifS (L 11 00 o c 4; with SL (ig.Z

Description

The invention relates to agricultural machinery, in particular to tools for tillage.

The purpose of the invention is to improve the leveling of the soil.

Figure 1 shows the instrument, top view; figure 2 - section aa in figure 1; on fig.Z - loose sh.iy working body leveling plate, side view.

The tool consists of a frame 1 with support wheels 2 and a hitch device 3. Frame 1 has reducers 4, to which spring-loaded rods 5 with holders 6 are hingedly attached, in which stands 7 are additionally attached. On the latter, an equalized plate 8 is fixed with loose working tools, each of which is made in the form of a rack 9 with a horizontal knife 10 located at its lower end. A rack 9 of the loosening working member is connected by means of a spring 11 to a housing 12 fixed to the rack 7 of the plate 8. The rack 7 has The bar 13 attached to it, to which is pivotally connected through a screw pair 14 and 15 of the sealing plate 16 with loosening working bodies 17 and 18. Nlita 16 is connected to the bar by means of the bar 19. The rack 9 of the loosening working body of the leveling plate 8 made in the form of a cone and set at an acute angle to the direction of movement of the gun. A rack 9 of the loose working member of the plate 8 is connected to the stand 7 of the plate B by means of a vertical hinge 20.

The tool works as follows.

In operation, the plate 8 cuts off the unevenness of the soil and moves a certain volume of the soil (prism dragging) forward. Racks 9 with knives 10 loosening workers crush the soil and prune weeds. Racks 9 with knives 10 loosening working bodies oscillate in the horizontal plane relative to the hinge 20, twisting the spring 11. At the same time, the cone forming the rack 9 when working in solid soil (in the cut-off area of the elevation plate 8) is removed the soil without dragging the prism of the trailing plate 8, without increasing its volume, which prevents the soil from flowing over

the upper edge of the plate 8. In soft soil (in the area covered by the plate 8 of the depression), the cone 9 which forms the cone rotates on the hinge 20 under the action of the spring 11 and approaches the plate 8 to the minimum distance at which the oblique cone 9 creates a sub seal soil. The stand 9 of the loose working body directs the loosened soil towards the treated floor, which reduces the uneven thickness of the mulch-niero layer, creates uniform density and improves the uniformity of the soil surface. At the same time, the return of the rack 9 of the loose working body to its initial position under the action of the spring 11 contributes to a more complete descent of the adhering pas

0 rack 9 and knife 10 soil and plant debris. Next, the soil surface is compacted on top of the plate 16, and its loosening working bodies 17 and 18 move the top layer of soil with crop residues and create a mulch layer

 for planting, as well as for the free passage of moisture and its long-term preservation in the soil.

Claims (1)

Invention Formula A tillage implement containing leveling and sealing plates mounted on a frame with loosening working elements fixed on them, characterized in that, in order to improve the quality of the leveling of the soil, each loosening leveling plate working body is made in the form of a rack fixed on its lower end horizontal knife, while the stand is set at an acute angle to the direction movement and is made in the form of a cone, and the larger base of the rack is connected to the leveling plate by means of a vertical hinge and is spring-loaded relative to the plate. 15 sixteen 18 18 17 P 1 Compiled by T.
