RU2311008C1 - Mounted plow with active moldboard - Google Patents

Abstract

FIELD: agricultural engineering, in particular, heavy soil tillage technique.

SUBSTANCE: plow has frame, casing with shortened moldboard and rotating moldboard mounted above shortened moldboard and provided with knives fused thereto by means of hard alloy. Knives are made curved in their upper parts along parabola, with apex oriented downward. Lower parts of knives, not in the excess of one third of knife height, are curved along hyperbola, with apex oriented upward. For overcoming of loads connected with operation on heavy soil and for uniform rotation, rotating moldboard is equipped with impeller.

EFFECT: improved quality of soil tillage.

Description

The invention relates to agricultural machinery, namely to tillage tools, and can be used in the processing of heavy soils.

Known plow with an active blade, in which the active blade is made in the form of a vertical rotor with loosening elements [1].

A disadvantage of the known device is that the working elements of the rotor are not cut, but beat the formation, mulching the soil and leaving an abundance of weeds without closing them.

The closest in technical essence to the claimed device is a mounted plow with an active blade, comprising a housing with a shortened blade and a rotating rotor with knives mounted behind it [2]. The knives are curved in the shape of a blade in section at the end of the share.

A disadvantage of the known plow is the poor incorporation of plant debris and poor mixing of the upper fertile and underlying infertile soil layers.

The objective of the invention is to improve the quality of soil treatment, in particular the complete incorporation of plant residues.

The problem is achieved in that in a plow with an active blade, comprising a body with a shortened blade and a rotating blade mounted behind it with knives deposited with hard alloy with a vertical axis of rotation, according to the invention, the knives in the upper part are curved in a parabola, with the top pointing downwards and in the lower part, not exceeding one third of the height of the knife, along the hyperbole, with the apex pointing up. In addition, the plow is equipped with a flywheel mounted on a shaft at the top of the active blade.

New in the device is the shape of knives curved along a parabola in the upper part and along a hyperbole in the lower, as well as the presence of an active blade on the flywheel shaft in the upper part of the blade.

Thus, the invention meets the criterion of "novelty."

The invention meets the criterion of "inventive step", since a result can be achieved that satisfies an existing need, namely, improving the quality of tillage.

The invention is "industrially applicable", as it can be used in agriculture.

The invention is illustrated in the drawing, which schematically shows the working body of the plow with an active blade, side view.

A plow with an active blade consists of a frame 1, a plow blade with a shortened blade 2, a ploughshare 3, an active blade 4. An active blade 4 is a shaft 5, on which four double-edged knives 6 are mounted, curved in the upper part along a parabola, and in lower, not exceeding one third of the height of the knife along the hyperbole.

In order to better overcome the loads associated with working on heavy soils, the active blade 4 also has a flywheel 7, which significantly reduces the inertia forces and promotes a more uniform rotation of the active blade 4. The flywheel 7 is made in the form of an all-metal truncated cone and is mounted on the shaft at the top of the active blade 4.

The plow works as follows.

When the unit moves, a plow body with a shortened blade 2 cuts the formation and feeds it to the active blade 4. The lower infertile soil layer, trimmed by the share 3, falls onto the lower part of the knife 6, curved along the hyperbole, with the apex, upward, crumbles and flips 180 °. The upper fertile soil layer with stubble, cut off by the upper part of the knife 6, curved in a parabola, with the top pointing down, is crushed and turned 180 °, covering all plant residues. In this case, the upper fertile and lower infertile layers do not mix with each other. The fertile soil layer always remains at the top, thereby increasing crop yields.

After the passage of the claimed device, the field surface is smoothed, without ridges, furrows and air pockets. The entire arable layer at a plowing depth of 25 cm is listened to 43 cm with the incorporation of all crop residues to a depth of 10 ... 12 cm.
