Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in tools for soil cleavage. The purpose of the invention is to reduce traction resistance. The knife 10 of the slit-on-base is mounted with a support on the adjustable liner 8 and with a gap relative to the middle of the plates 6 forming the tip. This allows the blade 10 to make elastic oscillations in the direction of movement due to changes in the load force from the non-uniform soil. When the knife 10 is worn, its elastic properties are restored by rearranging the insert 8 to change the point of bending of the knife 10. Performing the arm of the arm can also dry out soil-free tillage with or without shading. 1 hp ff, 3 ill. (L

 FIG. 2

The invention relates to agricultural machinery, in particular to tools for the main tillage in the forest-steppe and steppe zones. .

The purpose of the invention is to reduce traction resistance during tillage.

FIG. 1 shows the working body, side view; in fig. 2 - slit-tip of the working body; in fig. 3 is a section A-A in FIG. one.

The working body for soilless tillage contains a stand 1 with a shoe 2 and plowshares 3. A stand 5 is attached to the stand 1 by means of a bracket 4 in the form of a shlerereza. Shelerez-bolt 5 consists of three rigidly connected plates 6 and has eyelets 7 for bolting to the rack 1. Between the outer plates 6 of the arm 5 by means of an adjustable liner 8 and screws 9 fixed knife 10. The arm 5 has a short 11 and a long 12 shoulders. The knife 10 rests on the insert 8, and in the lower part the knife 10 has a gap relative to the middle plate 6.

For working in shearing mode with a flat cut tillage, first set the depth of the flat cut tillage. Shelerez-nalalnik 5 is installed with a long shoulder 12 down, this shoulder 12 is located below the edge of the flat-skinned paws and has a tilt angle of 55 °. When moving, the arm 5 and the pectoris paw zaglub

five

They enter the soil, while the rollers do not form, and the top of the shelter is covered with loose soil. Due to the heterogeneity of the soil, the load on the knife 10 varies, and it oscillates between the plates 6 in the direction of movement due to the support on the liner 8. The oscillation amplitude is limited by the gap between the middle plate 6 and the knife 10, which prevents the latter from damage.

To restore the elasticity of the knife 10, the insert 8 is rotated 180 ° (previously removed into the knife). This changes the bending point of the knife. With considerable wear, the knife 10 is replaced with a new one.

When flat-cut machining without w, it should be set with a short arm 11.

Claims (2)

Invention Formula 20 1. The working body for soilless tillage, containing a stand with a paw, and located in front of the standpipe, which is different in that, in order to reduce the drag resistance, the shelera.zalnicki is made of interconnected plates with them with a knife with the possibility of oscillation of the latter in the longitudinal-vertical plane. 2. A working member according to Claim 1, characterized in that an elastic liner is disposed between the knife and one of the plates of the arm. 25 g / ten Fig.Z
