Abstract

The invention relates to the field of agricultural engineering. The purpose of the invention is to improve the quality of tillage and complete weed control. The working body of the cultivator-flat-cutter contains a paw 2 mounted on a rack with wings 3 and a nose slat 4. The cut of the blade 5 of the latter has an arched shape, and the angle of the side blades 6 of the slat 4 is 2γ 2 = α, where α is the amplitude of angular oscillations. Each of the side blades 6 of the slat 4 is matched with the wing 3 of the leg 2 along a curved line and is located tangentially to it. The interface point of the curvilinear segment 7 of the paw with the side blade 6 is located at the intersection of the side blade 6 with the perpendicular to it passing through the axis O of the oscillations of the paw 2. The blade 9 of the wing 3 is located tangentially to the back of the curvilinear portion of the paw 2. When oscillating The paws 2 of the soil and the roots of the roots are cut by the front 5 and side blades 6 of the slat 4, while the uncut roots of the roots along the curvilinear section 7 enter the wing 3 paws 2 and are cut by reverse turning the paws 2. 1 Il.

Description

The invention relates to the field of agricultural engineering. The purpose of the invention is to improve the quality of soil cultivation and the completeness of weed control. The working body of the cultivator-plane cutter contains mounted on the rack 1 paw 2 with wings 3 and a nasal slat 4. Pered2

the blade of the nasal slat has an arcuate shape, and the angle of the lateral blades 6 of the slat 4 is 2 arc = a, where a is the amplitude of the angular oscillations. Each of the side blades 6 of the slat 4 is associated with the wing 3 of the legs 2 along a curved line and is located tangentially to it. The point of contact of the curved section 7 of the legs with the side blade 6 is located at the intersection of the side blade 6 with a perpendicular to it passing through ¹ axis 0 of the oscillations of the legs 2. The blade 9 of the wing 3 is located tangential to the rear of the curved section 7 of the legs 2. When the legs 2 the soil and roots of the roots are cut by the front 5 and side blades 6 of the slat 4, while the uncut roots of the roots along the curved section 7 enter the wing 3 of the legs 2 and are cut during the reverse rotation of the legs 2. 1 ill.

The invention relates to agricultural machinery, namely to the active working bodies of the cultivators of flat cutters and is additional to the main one according to ed. St. No. 1130181.

The purpose of the invention is to improve the quality of soil cultivation and the completeness of weed control.

The drawing shows the working body of the cultivator-plane cutter, top view.

The working body of the cultivator-plane cutter contains a paw 2 mounted on a vertical strut 1, having wings 3 and a nasal slat 4. The paw 2 has a mechanism (not shown) that informs it of angular oscillations. The front blade 5 of the latter has an arcuate shape.

The center O of the arc of the circumference of the front blade 5 is located at the intersection point of the perpendiculars to the side blades 6 of the slat 4 passing through their extreme front points. The angle of solution of the wings 3 of the legs 2 is 2γι = π — a, and the angle of the solution of the side blades of the slat 4 is 2y2 == = a, where a is the oscillation amplitude of the legs 2. Each of the side blades of 6 slats 4 is conjugated with the wing of 3 legs 2 by curved line, for example along an arc of a circle.

The point of contact of the curved section 7 of the leg 2 with the blade 6 of the slat 4 is located at the intersection of the blade bis perpendicular 8 to it, passing through the axis 0 of the oscillations of the legs 2. The blade 9 of the wing 3 is tangent to the rear of the curved section 7 of the legs 2, and the blade 6 of the slat 4 - tangent to the front of the curved section 7 of the legs 2.

The working body of the cultivator-plane cutter works as follows.

When transmitting rotation from the tractor power take-off shaft to a mechanism that converts rotational motion into oscillatory motion, paw 2 oscillates in the horizontal plane, simultaneously with

this moving in translational motion. When paw 2 is turned in the direction

5, in a clockwise motion, the soil and the weed roots located therein are deformed due to cutting cutting and cutting with the sliding of the blade 9 of the wings 3 and the blade 6 of the slat 4. The curved section 7 of the foot 2 deforms the soil and the weed roots contained therein by sliding cutting. Not completely cut by the front blade 5 of the slat 4, the roots of individual weeds due to the translational movement of the paws 2 are moved

15 along the side blade 6 and are cut by chopping and by cutting with sliding. The remaining uncut weed roots along the curved section 7 of the legs 2 enter the blade 9 of the wing 3 and are completely cut when the legs 2 are turned in the opposite direction.
