RU16051U1 - WORKING BODY OF THE SEED-CULTIVATOR FOR SUBSIDIALLY-SPREAD SEEDING - Google Patents

Description

The utility model relates to agriculture, in particular, to seeders-cultivators for subsoil-dispersed sowing. Known working body (opener) of the seeder-cultivator of the grain-fat stubble press wide belt sowing 030-2.1 L, see the technical description and operating instructions for this seeder of the Tselinogradselmash plant, 1985, from 15-16, photocopies of these pages are attached on two sheets ( 1). This working body (opener) consists of a vertical tubular stand 11, to which, using bolts 1, a straight vertical bump 13 is attached, and a tray 12. A lancet foot 14 is attached to the lower part of the bump (rack) 13. A seed distributor 4 is installed in the sublap space ( Fig. 4.5.1 and Fig. 4.5.2), which allows sowing seeds with a wide ribbon. The disadvantage of this working body is that a straight vertical narralnik 13 and a horizontally located paw 14 form an angle in the longitudinal-vertical plane of a straight (90) angle (see Fig. 4.5.1 and 4.5.2 on pages 15 and 16). In addition, the bolts 1, with the help of which the mouthpiece 13 is attached to the tubular stand 11, reduce the speed and uniformity of the flow of seeds coming from the seed box through the vas deferens into the ankle space. During the operation of such a coulter, the transition zone from the paw to the oral-kulobovy surface is clogged with soil mixed with plant residues (weeds, stubble). At the same time, due to the soil build-up, the dimensions along the width of the frontal part of the working body increase, which leads to a deterioration in the performance of the seeder:

the width (top) and the depth of the furrow left by the coulter, which leads to an increase in the crestiness of the field surface. In addition, seeds are unsatisfactorily planted in depth, since after passage of the coulter the sown seeds are insufficiently sprinkled with soil. This design during operation also leads to increased traction resistance of the working body and the seeder as a whole.

Also known is the Subsoil-spread coulter for the stubble seeder SZS-2.1, see Recommendations for improving the machines of the soil protection complex, M., Kolos, 1983. from 20-21, photocopies of these pages are attached (2).

In this opener, along with the established: in the subaxillary space, a wedge is installed on the frontal surface of the dowel in the area of its transition to the paw with a curved seed diffuser. However, this upgrade degrades the opener performance. At the same time, the plant residues, falling on the wedge blade, are bent and overhang together with adhering soil on the frontal surface of the opener. At the same time, the lump of adhering soil is mixed with plant residues, fixed and practically does not leave the coulter, and impairs the quality and energy performance of the coulter (seeder).

The purpose of the proposed utility model is to create a working body devoid of these drawbacks inherent in the known openers (1) and (2).

This goal is achieved by the fact that the coulter mouth is made curved (in profile) in the transition zone to the cultivator leg. At the same time, the paw is attached to the mouth with the help of bolts, and the mouth is welded to the stand, that is. bolts 1 installed in the analogue - in the proposed design - are excluded.

) Q. /,

- 2 List of figures in the drawings.

Figure 1 shows the proposed working body of the seeder, a side view in section. Figure 2 shows a top view of the proposed working body of the seeder,

The proposed working body of the seeder consists of the following parts and assemblies.

Wound, .. the working body is made with a smooth curvilinear transition to the shank of the legs E (figure 1). The paw S is attached to the mouth 1 with two bolts 3, and the mouth 1 is welded to the upright 10.

On the back side (in the direction of the drill), a tray 4 is attached to the sprayer 1 with two shields on both sides of the tray. A 5-seed reflector is bolted to the back of the tray with a nut.

A reflector 6 is welded to the narralik 1 from the inside and from the bottom in the area of the sub-pit space, on the rear vertical wall of which a seed diffuser 7 is mounted, which ensures the dispersion of seeds over the entire width of the paw (bottom of the furrow).

To the inner surface of the narralik 1 above the diffuser 7 is attached a guide 8 of the seed flow. In the vertical tubular rack 10 of the seeder is installed vas deferens 9.

The proposed working body of the seeder works as follows. During the work of the seeder, the coulter (working body) moves in the soil. Sown seeds and fertilizers are distributed evenly along the bottom of the furrow. The soil cut by the lancet paw 2 moves along the surface of the paw, along the curved part of the (frontal) surface of the narral and smoothly rises to a certain height from the field surface and leaves the paw and the frontal surface of the narral. The transition zone of the lancet paw to the curved bark (in profile) is not clogged with soil mixed with plant debris.

- 3 names of the Fighters of the revolution for the spring field work of 2000 in the amount of 120 sets - 120 seeders SZS-2.1. It was converted in the farms of the Omsk region and other regions of Russia. All these seeders passed a wide economic check. Farm reviews are only positive.

When using the proposed working bodies sharply (significantly) improved the performance of seeders:

-financing of the surface of the field has decreased;

-the quality of distribution (dispersion) of seeds over the sown area has improved;

- traction resistance of the seeder decreased by 15-20%;

- coulters are not clogged with soil.
