Abstract

The plough body separates the soil during ploughing not only by cutting, but also by splitting and tearing. The plough body has replaceable flat wedges fixed on the front edge of the ploughshare and intermediate wedges in the gaps between them. The tips of the intermediate wedges are located in one plane with the central axis of the replaceable flat wedges.

Description

The invention relates to a plow body which solves the uncoupling of the soil by plowing not only by cutting it, but also by splitting and tearing it with flat wedges.

Existing plow bodies are provided with a blade which, by uncoupling the soil only by cutting, has a negative effect on the physical condition of the soil, its air and water regime, the structural condition, while the blade compactness promotes the formation of lumps in furrows. energy, slow down the formation of a continuous capillary system between the subsoil and the future seedbed and undesirably extend the period between plowing and seeding. By breaking the formation of the plow sole, compacting and spreading the soil across the wide bottom of the furrow, it worsens the water and air permeability of the soil. The structural condition of the soil is negatively influenced by the fact that the soil aggregates do not separate from each other in the places of the smallest aggregation forces, in the inter-aggregate spaces, but they cut them apart and act disaggregating.

The above-mentioned drawbacks of the current plows are substantially eliminated by the plow body according to the invention, which is characterized in that replaceable flat wedges are fixed in the front part of the deburrer and cracks are formed in the gaps between them. The crevices have spikes aligned flush with the centerline of the replaceable flat wedges.

The flat wedges, when moving through the soil, disconnect this by both cutting and tearing. The tearing and splitting of the soil between the wedges saves the soil structure in the furrow ditch and at the bottom of the furrow, where it still has an anti-compacting, ameliorating effect, because the soil elevation that occurs here tears, increases soil at the bottom of the furrow. the permeability of the gaseous and liquid phases of the soil and the formation of scraped bands counteracts the integrity of the plow sole, thereby facilitating root growth. The considerable heterogeneity of the forces exerted on the z06 min when plowing by the proposed plow body causes the stresses already in the emerging furrow dump, and it breaks down without the formation of large lumps. The smaller clodiness of the plowed bed reduces the loss of moisture by evaporation, accelerates soil preparation under the sow and reduces fuel consumption.

The attached drawing shows an example of a plow body according to the invention, in which FIG. 1 is a plan view of a plow body and FIG. 2 is a section along line A - A of FIG. First

Equally long interchangeable flat wedges 2 are fastened to the front edge 7 of the skidder 1, perpendicular to the plowing direction, between which grooves 3 are formed in the gaps 4. The length of the inter-wedges 3 is equal to 1/3 of the interchangeable flat wedges 2. the edges 8 have an angle of 20 °, the tips 5 of the gaps 3 having an angle of 35 °. The gaps 3 have the points 5 aligned flush with the central axis 6 of the interchangeable flat wedges 2.

The interchangeable flat wedges 2, with their cutting edge 8, disengage the soil and create a furrow heap which is formed at the locations of the replaceable flat wedges 2 by cutting and in the spaces 4 between the replaceable flat wedges 2 by tearing off. The muddy soil cut off by the cutting edges 8 of the interchangeable flat wedges 2 moves along the surface of the interchangeable flat wedges 2 to the deburrer 1, while the soil in the gaps 4 between the interchangeable flat wedges 2 is separated by tearing. 2, the gap 4 between the replaceable flat wedges 2 and the gaps 3 is a source of polyvector forces when the plow body according to the invention moves through the soil, which causes numerous stresses to form in the furrow dump and breaks into a furrow dump agronomically desirable size fractions.
