Description

(54) SOIL PROCESSING BRIDGES

one

The invention relates to tillage tools, in particular to tillage brackets, mainly for crushing a formation reinforced by perennial roots, for example, when inspecting vineyards for infection with 5 phylloxera.

A digging bracket is known, which includes a digging tine with stanchions and an extender-ripper, made on a comic ploughshare protrusion in the form of separate straight parallel rods. This brace provides intensive fortification of the formation processed in the nursery.

However, when cutting a stratum between the perennial plants, for example, a detailed survey of the vineyards on the infestation with a phylloxera ripper infestation of the staple cannot sufficiently destroy the stratum compacted by the passages of masinins and people and reinforced by roots that extinguish the main destructive stresses.

Closest to the proposed tillage bracket includes undercutting plowshares with side racks, on which the extender-ripper is rigidly fixed, made in the form of curvilinear rods 2.

However, this device does not sufficiently intensively break up the cut formation, due to the design of the extender-ripper.

The purpose of the invention is to increase the intensity of the fracturing of the soil layer.

This goal is achieved by the fact that the rod is fixed on the plowshare fan-shaped by its convexity to the side racks.

With this design, the extender rod is stretching the layer to the side of its axis of symmetry. have an effect on it, in which the destructive stresses do not dissipate across the entire width of the reservoir, but are concentrated in one place — along its axis of symmetry, where a deep fracture of the formation occurs, exposing the roots located in it. The ripper rod, which coincides with the axis of symmetry and the direction of movement of the reservoir, serves as a guide for lifting the cut and bare roots onto the soil surface, during which they are separated from the fractured reservoir.

FIG. 1 shows a bracket, side view; in fig. 2 - the same, top view; in fig. 3 is a view along arrow A in FIG. one.

The tillage bracket includes side racks 1 and undercut ploughshare 2, on which extension cord 3 is rigidly fixed. Side racks 1 are made cutting, trim plowshare 2 is curvilinear, and the extender mounted on it is a set of curvilinear rods; central 4 and lateral 5. Rod 5 are installed fanlike relative to the central rod 4 with their bulges toward the side racks.

Staple works as follows.

When the tractor moves forward, the clamp enters the soil to a predetermined depth and cuts the layers between the perennials between the perennials. Moving along the trimming ploughshare 2 and the ripper extender 3, the cut out layer begins to break down, and the intensity of the breakdown especially increases due to the breaking action of the ripper bars 5 of the shredder, whose curvature is convex at an angle to the direction of the formation movement. A deep longitudinal fracture occurs along the axis of symmetry of the reservoir, exposing the root segments. These roots, depending on the ripper rod 4, coinciding with its axis of symmetry and the direction of movement of the reservoir, are separated from the fractured reservoir due to the influence of the rods of the slide process along the rod 4 when it rises to the soil surface.

In connection with the destruction of the formation cut by the cramp, mainly due to tensile stresses, the use of the invention will intensify the process of fracturing the formation and separation of the perennial root segments from it with minimal energy consumption.

that the resistance of the soil to stretching is 2.5 times less than its resistance to compression.
