SU1493126A1 - Soil ripper - Google Patents

Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, tools for processing deflating soils. The purpose of the invention is to improve the quality of tillage and reduce traction resistance of the ripper. A corrugated circular knife 4, mounted in front of the 2-loosened paw 3, cuts the soil in a vertical plane. The width of the corrugated part of the circular knife 4 at its base is larger than that of the blade, as a result of which the lower soil layers are not carried out to the surface. The width of the disk knife 4 at the base is larger and equal to the width of the rack 2. The rack 2 moves in the soil along the groove 4 formed in it with a disk knife, which does not lead to the destruction of the stubble cover and reduces the drag of the cannon. 1 hp f-ly, 2 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, tools for processing deflating soils.

The purpose of the invention is to improve the quality of soil treatment and reduce the drag resistance of the ripper.

FIG. 1 shows the cultivator defliryush, their soil, side view; in fig. 2 - the same, top view.

The cultivator of deflated soils contains a frame 1 with a flat-cutting loosening paw 3 installed on it by means of a stand 2. Before the stand 2 there is a corrugated circular knife 4. The width of the corrugated part of the knife 4 at the base of b is larger than it

ten

Chimic body - flat-cutting paw 3 In this case, the rack 2 does not destroy the stubble cover and does not form deflating particles. Due to the width of the corrugated part of the knife 4 at the base of b0 more than that of the blade 6, the soil is not removed from the lower layers and sprayed. Cutting the soil with a grooved disk knife 4 reduces the traction resistance of the rack 2 of the working body 3.

Claims (2)

Invention Formula I. Ripper of deflated soils containing a frame with flat blades installed on it, blade bj,. At the same time, the width 15 of the corrupting loosening paw, in front of the rifleed part of the knife 4, in its base of which a corrugated disk knife is installed, characterized in that, in order to improve the quality of processing of deflating soils and reduce the traction resistance of the ripper, B o is equal to or greater than the thickness of a stoic 2, i.e. b. The ripper works as follows. Forward motion grooved the circular knife cuts the soil and plant residues in a vertical plane in the direction of movement of the gun. In this case, a gap is formed, the width of which L0 on the soil surface is equal to or greater than the thickness a of rack 2. The soil loosens the working of the disc knife at its base more than by the blade. 2. A ripper according to Claim 1, characterized in that the width of the corrugated part of the knife at its base is equal to or greater than the thickness of the loosening paw. Chimic body - flat-cutting paw 3 In this case, the rack 2 does not destroy the stubble cover and does not form deflating particles. Due to the width of the corrugated part of the knife 4 at the base of b0 more than that of the blade 6, the soil is not removed from the lower layers and sprayed. Cutting the soil with a grooved disk knife 4 reduces the traction resistance of the rack 2 of the working body 3. Invention Formula A new knife, characterized in that, in order to improve the quality of processing of deflating soils and reduce the drag resistance of the ripper, the width of the corrugated part disk knife in its base more than the blade. 2. A ripper according to Claim 1, characterized in that the width of the corrugated part of the knife at its base is equal to or greater than the thickness of the loosening paw. qjas2
