I.T. Ergashev, A.A. Akhmetov and others conducted

research in this direction in our republic.

Plugs created on the basis of the results of these

studies are being used in agricultural production with

certain positive results. However, in these studies, the

issues of justifying the parameters of the active

working body of the combined frontal plug, which

provide high work quality with low energy

consumption, have not been sufficiently studied.

2 MATERIALS AND METHODS

In order to verify the results of the theoretical studies

and to determine the parameters of the combined

frontal plug active working body that ensure the

required quality of work with low energy

consumption, the following were included in the

experimental research program:

• development and construction of a laboratory-

field device for conducting experimental

studies;

• to study the influence of the number, diameter,

kinematic mode of operation and processing

depth of the blades of the active working organ

on the quality indicators and traction resistance

of the plug;

• using the method of mathematical planning of

experiments, justifying the optimal values of

the parameters of the active working body of

the combined frontal plug;

• conducting comparative tests of a device with

a passive and active working body.

The following agrotechnical parameters of the

plow were determined in experimental studies:

coverage width, tillage (plowing) depth, level of soil

crushing.

To determine the actual coverage width of the

plow with an active working organ, the plowed field

was divided into 50 m long zones, and wooden stakes

were driven every 5 m along a straight line at a

distance of 10-15 m from the edge wall of the last pass

of the plow. Before and after the passage of the

driving unit, the distance from the opposite side of

each pile to the egate wall was measured with a tape

measure with an accuracy of 0.5 cm. The difference

in these dimensions gave the actual coverage width of

the plug with the active working organ.

The plowing depth was measured using a special

depth gauge. The number of measurements is at least

25 times.

The plane of the plow surface after the driving

unit passes yin was determined. On the surface of the

plow, perpendicular to the direction of movement of

the unit, a special rail with 5 cm sections was installed

on wooden pegs driven over the entire width of the

plug. The alignment of the rail was checked with a

level gauge. Then the distance from the lower edge of

the rail to the surface of the plow was measured.

Measurements were taken from 21 points at 5 cm

intervals and at 3 locations along the length of the

plow in one pass of the driving unit.

The plane of the bottom of the plow was

determined in the same way as above. Only in this

case, the plowed soil in the entire coverage width of

the plow with an active working organ was removed

and measurements were made.

3 RESULTS AND DISCUSSION

During experimental research, the device was used in

conjunction with the Claas ARION 630C tractor of

the 3rd class.

During the experiments, the transverse distance

between the working bodies was changed from 10 cm

to 25 cm with an interval of 5 cm. Each option was

conducted at aggregate speeds of 7 and 9 km/h. In

addition, when one parameter was changed, other

parameters remained constant, i.e. remained

unchanged.

A mathematical method of planning experiments

was used to optimize the parameters of active

working bodies. Experiments were conducted based

on a four-factor plan (Akhmetov et al., 2023, Akhmetov

et al., 2021).

According to the initial data obtained in the

experiments, mathematical statistical methods were

used to determine the arithmetic mean values and

I-CRAFT 2024 - 4th International Conference on Research of Agricultural and Food Technologies

mean square deviations of the indicators

(Vedenyapin, 1973; Kobzar, 2006; Johnson & Lyon,

1990).

The tests were carried out at speeds of 7.8 and 9

km/h. In this case, the depth of processing with active

working bodies was determined to be the same for all

options, i.e. 12-14 cm.

The experiments were carried out in the summer

months of June-July in the fields of the experimental

plot (Fig. 1).

Figure 1: Working process of combined frontal plug with

active working body.

Figure 2: Placement of measuring instruments in the tractor

cab.

A measuring cylinder was used for determination,

and the volume of fuel in it was recorded on a

continuous basis.

During the experiments, measuring instruments

were placed in the cab of the tractor (Fig. 2).

The lack of possibility to comprehensively take

into account in theoretical research the properties of

the soil of grain-growing zones, which affect the

process of flat plowing, requires extensive laboratory-

field experiments.

The energy and quality indicators of plugs,

including the combined frontal plug, depend on its

design parameters (covering width of the body, mutual

arrangement of working bodies, size of overlapping

between plowshares, location of the active working

body and its parameters, etc.) depending on the laws

of change and technological and operational

parameters (driving depth, driving speed and

kinematic working mode of the active working body),

the mechanical composition of the soil, moisture,

density, microrelief and other properties.

Accordingly, research was conducted on typical

wheat-free fields and the following were considered:

Conditions and Methods of Research of the Combined Frontal Plug Active Work Body

• to determine the quality and energy indicators

of the flat working plug with active and passive

working body depending on its structural and

operational parameters;

• to determine the nature of changes in the

quality and energy indicators of the frontal

plow depending on the structural and

operational parameters of the active working

body that processes the surface layer of the soil;

• conducting comparative economic tests of a

combined plow with active and passive

working organs.

In the course of the research, the following

aggregate technical parameters of the working

process of the two-body device were determined:

coverage width, plowing depth, level of soil crushing,

depth and level of burial of plant residues.

4 CONCLUSIONS

Thus, in addition to performing the function of a

mover with the help of active working organs, it

ensures the improvement of the work quality and

energy indicators of the plug in soils with low

moisture and high density of the surface layer.

According to experimental studies, in order to

ensure the required soil compaction with minimal

energy consumption at 22-26 cm working depths of

the hulls, the active working body should be installed

at a distance of 40 mm forward from the nose of the

hull plow and 30 mm to the side of the hull. will be

compatible
