BDM four-row disc harrows. BDM four-row disc harrows Structural weight without roller

Description

Four-row disc harrow PM-5x4PK It is a trailed, sectional structure. Spherical discs are installed obliquely, on individual racks, in 4 rows, with the angle of attack of the discs changing synchronously in each row.

Disc harrow PM-5x4PK used in various agroclimatic zones, on all types of soils, including those subject to wind and water erosion, except rocky ones.

Effective for introducing fallow lands into circulation, basic and pre-sowing cultivation in a minimum tillage system, rejuvenation of degrading meadows and pastures.

The use of a disc harrow has a positive effect on soil fertility and restores the natural humus layer with a significant reduction in costs.

Working parts of a disc harrow PM-5x4PK are spherical cut-out disks mounted on individual stands at an angle to the vertical.

The discs, rotating while the unit moves, trim and crumble the treated soil layer. Cutouts in the discs improve crushing of the formation, as well as cutting and throwing plant residues onto the soil surface. The soil thrown away by the spherical discs comes into repeated contact with the rotating discs, is further crushed and mixed with plant residues. As a result, a uniform layer of mulch is formed throughout the entire depth of processing.

The track roller mechanism consists of:
– stops;
– damper spring (protects against dynamic shocks);
– lanyard.

The support roller mechanism allows you to adjust the depth of tillage, regardless of the angle of attack of the disks (from 5 to 15 cm).

Possible configurations of the track rollers of the disc harrow BDM-5x4PK

Spiral track roller for disc harrow

Made from square rod (25 mm x 25 mm). Ideal for disc harrow operation PM-5x4PK for dry and low-moisture soils (at high humidity it is prone to sticking).

Frame

The disc harrow frame is made of pipe 150 x 100 x 6 mm.

Jack

Disc harrow PM-5x4PK as standard, it is equipped with a jack to facilitate assembly with the tractor.

Towbar earring

The tow bar consists of two sheet parts, reinforced with ribs, and a bushing with chamfers.

The chamfers on the inner surface of the bushing prevent wear and significantly increase the durability of this unit.

Serviceable disc harrow stand

Standard equipment for a disc harrow PM-5x4PK includes a reinforced stand Ø58 mm. with a serviceable connection “post – frame bushing”. Periodic lubrication prevents coking of this interface.

Possible disk configurations

The standard equipment of the disc harrow is “Romashka” discs Ø560 mm, thickness 6 mm. (with six holes for the hub of the cutting unit). The discs are made of boron steel 65G.

Equipped with “DROP” discs for a 4-row disc harrow PM-5x4PK is a recommendation and their installation is available as an option.

Advantages of “DROP” discs

Due to the “flowing” of part of the cut soil through the holes in the disk:
– traction resistance on the tractor is reduced;
– engine service life increases;
– fuel consumption is reduced (up to 15%);
– soil crushing is improved (when soil passes through holes
additional crumbling and crushing occurs on the rotating disk);
– sticking of the inner surface of the discs is eliminated even when working on heavily moist soils.

The discs are made of boron steel 65G. Disc dimensions: Ø 560 mm, thickness 6 mm. (with six holes for the hub of the cutting unit).

Parallel lifting and thrust vector adjustment mechanism

Instead of the bulky lever and lanyard (used by other manufacturers), the disc harrow has an adjustable stopper, consisting of a hydraulic cylinder and a set of folding shims.

Adjustment occurs by changing the number of washers working point-blank.

This stopper also serves as a locking mechanism for the hydraulic cylinder in the transport position.

Chassis on a single frame

Chassis on a single frame The transition from a separate chassis to a chassis on a single frame made it possible to get rid of the “waddling” effect when moving the implement to the transport position, which led to additional bending loads on the frame structure.

Disc harrow frame design PM-5x4PK is freed from this drawback and has increased rigidity and increased service life.

The disc harrow BDM - 5x4P is intended for loosening and preparing the soil for sowing; destroying weeds and chopping crop residues; for pre-sowing soil preparation without preliminary plowing and tillage after harvesting thick-stemmed row crops.

The harrow is designed to work on soils with different physical and mechanical properties with a field surface slope of up to 10°, flat and wavy microrelief, soil moisture up to 28%, soil hardness in the treated layer up to 3.5 MPa, height (length) of plant residues up to 25 cm.

The location of each disc on an individual axis, independent row adjustment of the angles of attack of the discs help improve the agrotechnical performance of soil cultivation, as well as reduce the traction force of the tractor. The absence of a single axis for several disks eliminates the winding of plant debris and eliminates the need to use scrapers in the design. The paper machine allows you to reduce the tillage time by 2-3 times due to the four-row arrangement of disks, combining 3-5 operations in one pass.

The disc harrow BDM - 5x4P is equipped with a spiral or ring-spur roller. The roller is designed to crush, level and compact the soil after disking. In the stubble of grain crops, the ring-spur roller allows you to cultivate the soil for sowing in one pass.

The roller diameter is 506 mm, weight – 638 kg.

Four-row modernized disk harrow PM with a bearing unit inside the disk sphere, with disks on an individual stand, with a change in the angle of attack of the disks synchronously in each row, designed for surface tillage to a depth of 17 cm, destruction of weeds and grinding of crop residues. Due to the uniform mixing of soil with plant residues, the use of a disc harrow is effective on soils subject to wind and water erosion. Plant residues, evenly mixed with the top layer of soil, protect the soil from blowing and washing away and improve air exchange. At the same time, plant residues, while in the ground, are actively converted into humus, increasing soil fertility.

The four-row disc harrow is used in various agroclimatic zones of Russia, on all types of soils, except rocky ones. The use of a four-row harrow is effective for introducing fallow lands into circulation, basic and pre-sowing cultivation in a system of minimal tillage, and rejuvenating degraded meadows and pastures.​

Advantages of 4-row PM harrows compared to 2-row:

Four-row harrows have a fairly large distance between discs in a row. The distance between discs in a row is 460mm, the distance between rows is 675mm. Therefore, the earth thrown up by a row of disks easily passes between the disks of the next row. Thus, the four-row harrow is capable of working in fields with large weeds and to great depth.

The long frame helps smooth out small unevenness in the field. Four-row machines are excellent levellers, easily smoothing out ridges, camber furrows, deep ruts, molehills, etc. Thus, a four-row harrow is indispensable for bringing fallow lands into circulation.

The main advantages of 4-row implements over competitors:

1. At BDT-AGRO, research was carried out, a new, rational arrangement of disks was developed and repeatedly tested. The distance in a row for four-row machines was 460mm. This made it possible to reduce the tractor power and save up to 12% of fuel compared to implements of similar working width from other manufacturers, without compromising the quality of tillage.

2. On BDT-AGRO implements, the disc rack has a channel and groove for lubrication. It is enough to lubricate once a season, so each implement is equipped with only one special bolt with an oiler. In emergency cases, you can unscrew the rack mounting bolt, add grease and push it into the joint while tightening the same bolt. This significantly improved the performance of the connection and removal of the rack.

3. All implements are equipped as standard with a mechanism for adjusting the working depth (support roller). At the same time, the rollers located behind the chassis are adjusted using spring shock absorbers, which significantly reduces the load on the implement when working on uneven terrain and when the tractor is galloping.

4. A common disadvantage of all disc harrows is that the outermost disc of the last row leaves an open deep furrow. On the implements of BDT-AGRO LLC, the outermost post of the last row is 40 mm shorter than the other posts. As a result of this, the outermost disk of the last row is 40mm higher than the other disks. Consequently, it leaves behind a shallow furrow, although it trims, crushes and discards enough soil to cover the furrows left by the disks of the front rows and the disks of its own row. The final leveling of the field is carried out with a compacting roller. Thus, the patented design solution used on the implements of BDT-AGRO LLC improves the quality of field processing.

Description

FOUR-ROW DISC HARROW SERIES BDM LLC "BDT-AGRO" is a developer and manufacturer of agricultural implements: Modernized disc harrows (BDM) - trailed and mounted, 2, 3 and 4 rows with a working width from 2.1 to 9.3 meters. Four-row disc harrow of the BDM series with a working body on an individual stand with a change in the angle of attack of the discs synchronously in each row, designed for traditional, minimal, main and pre-sowing tillage (up to 17 cm) for all types of crops with grinding of crop residues and their incorporation into the cultivated soil layer of soil without prior plowing. Currently, BDT-AGRO LLC produces all disc harrows with lubricated tines. The bushing-post interface is lubricated, this prevents coking of the posts and increases the reliability of the disc harrow. The four-row harrow is used in various agroclimatic zones of Russia, on all types of soil. It is especially effectively used for peeling stubble, destroying weeds, cutting up layers of perennial grasses, cultivating the rows of gardens and vineyards, cultivating rice paddies, rejuvenating meadows and pastures. The new arrangement of discs of the BDT-AGRO harrow allows you to work in fields with high soil moisture (up to 40%), as well as in fields with a significant amount of crop residues and weeds. This prevents plants from wrapping around the disk axis and clogging the interdisk space. The main advantage of 4-row PM harrows compared to 2- and 3-row harrows is the greater number of working parts per “linear meter” of the implement. In other words, the largest number of working elements pass along the working width of the implement, thus, of all the disc implements, the four-row one (with proper adjustment and optimal weather conditions) gives the highest quality of tillage. The main advantages of 4-row implements over competitors: 1. The distance between the working bodies is 460 mm, which allows fuel savings of up to 12% compared to implements of similar working width from other manufacturers, without compromising the quality of tillage. 2. The distance between the rows of discs has been increased to 675 mm, which, unlike 640 mm for competitors, allows you to work in high humidity and weedy fields. 3. The lubricated post-bushing connection prevents coking of the post in the frame. 4. Moving the chassis beyond the working part of the implement made it possible to maintain the specified tillage depth in unleveled fields. 5. All trailed-folding implements, as well as all mounted implements, are equipped as standard with a mechanism for adjusting the working depth (track roller). 6. All tools are made of profile pipe with a section of 150x100x6 mm. 7. Optionally, a maintenance-free cutting unit is installed on the standard diskator mounts (interchangeable with the standard one). As practice shows, one maintenance-free cutting unit can cover up to 70 hectares without any intervention. For example, a 4x4 PKS PM tool with 36 cutting units will work on an area of ​​2520 hectares. 8. A common disadvantage of all disc harrows is that the outermost disc of the last row leaves an open deep furrow. A patented design solution used on the implements of BDT-AGRO LLC - the outer rack of the last row is 40 mm shorter than the other racks. As a result of this, the outermost disk of the last row is 40mm higher than the other disks. Consequently, it leaves behind a shallow furrow, although it trims, crushes and discards enough soil to cover the furrows left by the disks of the front rows and the disks of its own row. Thus, the patented design solution used on the implements of BDT-AGRO LLC improves the quality of field processing. 9. The use of maintenance-free cutting units, FKL bearing units in the roller mounting, FREISER, BELLOTA disks, CAPRENEDOLO hubs, and other imported components made it possible to improve the quality of the tool and extend its service life. 10. The warranty for tools manufactured by BDT-AGRO LLC is 2 years (frame, straight stand, chassis, forklift), with the exception of wearing parts (disc, cutting unit, hydraulics).
