Abstract

The invention relates to agricultural machinery, in particular to tools for continuous tillage before sowing or before planting seedlings. The tillage implement contains a frame, a milling drum with sections of straight knives fixed to it, a set of passive, vertically mounted knives and a casing. Passive knives are contradictory due to their installation between sections of milling knives. The blades of passive knives have a slope opposite to the direction of movement of the unit, which eliminates the possibility of congestion and improves the cutting process of lumps of soil and plants based on the effect of scissors. 2 ill.

Description

 The invention relates to agricultural machinery, in particular to tools for continuous tillage before sowing or planting seedlings.

The aim of the invention is to guarantee the quality of crumbling. heavy and ordinary soils, the destruction of weeds and grinding of rhizome residues ..

Figures 1 and 2 show a tillage implement.

The tillage implement contains a milling drum, consisting of active knives 1, mounted on flags 2, mounted on shaft 3, forming sections along the width of the implement. Between the milling sections in the zone of depth of processing vertically mounted opposing passive knives 4 with a tip in the direction of movement of the tool. Each of the passive knives is attached to the posts 5, rigidly connected to the frame 6, Behind the milling drum and

passive knives on the frame 6 fastens the casing-equalizer 7, which has an additional adjustment link by means of the spring 8. The casing-reflector is made strong enough, because simultaneously performs the function of leveling the surface of the treated strip. Guaranteed crushing of the soil to obtain the necessary fractions is carried out by setting a certain technological gap in the working area between the side surfaces of the active 1 and passive 4 knives. The size of the technological gap b is adjustable and equal to

where t is the spacing of the milling knife sections on the drum shaft;

Bf, bn - the thickness of the milling and passive knives.

In case of equal thicknesses, the technological gap will be

, 5 t-b

The technological gap can be adjusted by changing the pitch of the arrangement of the milling sections.

To prevent clogging and the reliability of the soil cutting process, the blade of the passive knife has an inverse inclination to the movement of the implement.

Tillage weapon works as follows ..

When the unit moves at a predetermined processing depth, the active knives 1 of the milling sections on the milling drum are introduced into the soil along the movement of the unit, cut and deforming the soil. After turning about 30 degrees at maximum depth in the soil, the active knives 1 pass between adjacent vertically mounted passive knives 2, which in turn move at the speed of the gun. Thus, a forced and continuous incision of the soil occurs and the destruction of all lumps, the largest size of which cannot exceed the size of the technological gap b.

The experimental sample of the considered tillage implement has passed a wide production test. Preliminary theoretical calculations showed that the best results can be expected if the peripheral speed of the active knives exceeds the passive speed by about 4 ... 5 times, the so-called lead.

A sample of cultivating implements was used on pre-sowing and pre-planting soil preparation for sowing basma seeds and planting henna seedlings in

Kurdamir region of Azerbaijan. For comparison, similar processing was carried out in parallel with a local Shirvan-mal unit and a serial milling cultivator for surface tillage of KFG-3.6.

In order to obtain the quality processing indices obtained by the proposed tool, the KFG-3.6 serial milling cultivator had to perform 2-fold processing in the longitudinal-transverse direction, and Shirvan-mal 4-fold. It should be noted that the local Shirvan-mala are made from heavy pipes used in oil production, to which a large number of massive teeth are welded. Hence, it is not difficult to evaluate the economic efficiency of the proposed tillage implement.
