SU913962A1 - Sowing combined unit - Google Patents

Description

The invention relates to agricultural machinery, in particular to the combined sowing aggregates, mainly for early sowing of rice on overmoistened soil.

Known sowing combined units containing a wheeled tractor, a hopper for seeds and fertilizers with a sowing unit, seed lines, coulters, eagortachis and press rollers [1].

The disadvantage of these sowing combined units is that they do not provide high-quality early sowing on overmoistened soil due to the considerable weight and complexity of the unit due to the implementation of the bunker, openers, roll rollers as independent elements of the seeder attached to the tractor.

In conditions of high soil moisture increases its viscosity and stickiness, which leads to sticking of the rollers, openers of the seeder and the space between them, to the destruction of the row spacing. All this entails a malfunction of the openers and rolls, especially on overmoistened soils.

The purpose of the invention is the provision of the possibility of early sowing of seeds on wet soil and simplify the design of the unit.

The goal is achieved by the fact that the protectors “in the front wheels of the tractor are made with annular projections that act as openers, and a seed and fertilizer hopper with a sowing unit, seed tubes and overlays are located in the tractor's unwheelspace, and the rear wheels of the tractor are used as roll-in rollers.

FIG. 3 "cross section of the tractor front wheels tread; in fig. 4, node I in FIG. 3

Sowing combined unit contains a wheeled tractor, dual front 1 and rear 2 wheels placed in the inter-wheel space ^ a hopper 3 for seeds and fertilizers with a sowing unit 4, seed tubes 5 and elastic rubberized zagortach 6.

The tire treads of the front wheels of the tractor are made with annular protrusions 7, which act as openers. The height of the protrusions 7 and the distance between them in the transverse direction, respectively, are equal to the depth of seeding into the soil and the width of the rows.

The rear wheels 2 have a smooth tread and perform the role of packer wheels. A tail 8 is installed at the rear of the tractor. The width of the front and rear wheels is chosen such that it is equal to the distance between them in the transverse plane, which makes it possible to sow the soil placed between the wheel tracks during the subsequent tractor passes.

The unit works as follows.

When the tractor tires move 1, the front wheels with their annular protrusions 7 form grooves in the depth and width of the rows between the tractor weight and the tractor weight.

Seeds and fertilizers from the bunker 3 mounted on the tractor, by the sowing apparatus 4, through the seed tubes 5 are sown in the formed grooves. Rubberized elastic zagortach 6, installed in between the rows behind the seed lines at an angle to the groove, move the dry mulch layer from the row spacing to the groove, forming a small roller above it. Rear twin tires 2 wheels with a smooth tread roll down

and plan the formed soil rollers and at the same time reliably close up the sown seeds and fertilizers to a predetermined depth. Trailing behind

The 5 twin rear tires, train -8, produces surface loosening, which prevents compacted crops from soil crust formation and cracking.

Thus, the sowing unit with front wheels of a tractor with a tread in the form of rings and backdrops with a smooth tread in one pass in the early spring period for the overes, 5 lazhennoe soil of rice fields performs precise formation of grooves in depth and width between rows, sowing seeds and fertilizers , reliable their seal, rolling, planning and

2 ₀ surface loosening.
