Description

The utility model relates to the field of agriculture, in particular to machines that perform a number of agricultural operations in one pass.

A known unit for agricultural work, containing a reaper mounted on a self-propelled chassis, and on the chassis are mounted sequentially along the plowshares digging up the stubble, trays are installed above them, guiding chopped straw under the wheels (Utility model patent No. 32965 Combine harvester, Galkin I. BUT.).

Known mower with a rotary cutting device for mowing and grinding stubble, having three levels of disks (Polytechnical Dictionary / Ch. Ed. I.I. Artobolevsky. - M .: Soviet Encyclopedia, 1976. - P.232).

Known seeder for sowing grain crops and forage grasses (Utility Model Patent No. 32962, priority 02/12/2002, publication 10/10/2003).

Known field roller for post-sowing compaction of soil, whose width is greater than the diameter, and which is aggregated with agricultural machinery (Polytechnical Dictionary / Ch. Ed. I.I. Artobolevsky. - M .: Soviet Encyclopedia, 1976. - P.203).

However, when performing agricultural work with such aggregates, moisture loss occurs in the lower uncultivated soil layers and the weathering of the upper fertile soil layer occurs.

The purpose of the utility model is to improve the technological process in terms of creating a lower moisture-retaining soil layer and post-sowing compaction of the upper soil layer.

This goal is achieved by the fact that in the unit for agricultural work, containing a header mounted on a self-propelled chassis, and on the chassis are mounted sequentially along the unit of the share, digging up the stubble, dumps in front of each wheel of the chassis for cleaning the track and the formation of the embankment, trays are installed above them, shredded straw guiding the wheels, scrapers are fixed to the chassis behind the wheels, filling the track with a mound and leveling the restored soil layer, while an additional mower with rotational a cutting device for cutting and grinding stubble having three levels discs rollers A system for creating a lower water-retaining layer of the soil, in addition, introduced seeder for sowing crops and forage grasses, and also a field for posleposevnogo roller compaction.

Figure 1 shows the proposed unit for agricultural work (General view); figure 2 is the same, view aa. In the drawing: XM - grain mass, C - straw, IS - chopped straw, SR - straw chopper, IST - chopped stubble, VUP - water-holding strip, where a is the width of the roller, and c is the width of the wheels.

The proposed unit for agricultural work 1 consists of a self-propelled chassis 2 and a mounted header 3 containing a mower 4, reel 5, a conveyor of bread mass 6, a conveyor of straw 7 (figure 1). Sequentially along the unit after the header 3 there is a ploughshare 8 digging up the stubble, then dumps 9 in front of each wheel 10 of the chassis 2 for cleaning the track and forming a mound along the edges of the track. The straw chopper SR is fixed to the chassis 2 at the exit of the straw conveyor 7, as well as the chopped straw conveyor 11, which receives chopped straw from the straw chopper and guides it using trays 12 under the chassis wheels

2 (FIG. 2). Scrapers 13 are fixed to the rear of the wheels on the chassis 2, filling the track with a mound and leveling the restored soil layer.

Additionally, a mower 14 with a rotary cutting device for mowing and grinding IST stubble, which has three disk levels, a roller system 15 with pneumatic drives 16, providing the creation of a lower moisture-holding soil layer, was introduced into the unit. In addition, a seeder 17 was introduced for sowing grain crops and forage grasses, as well as a field roller 18 for post-sowing soil compaction.

The unit for agricultural work operates as follows.

During operation of the unit, the bread mass is fed to the mower 3 with a reel 4, mowed by a mower and fed by a conveyor 6 to the threshing drum and grain hopper (not shown in the drawing). The mower is followed by ploughshare 8, which dig up the soil with stubble after the mower. Further, the dumps 5 in front of each wheel 10 of the chassis 2 clear the ruts and form embankments on the sides of the rut. The straw (C) after the threshing drum through the conveyor 7 is fed into the straw chopper SR, where it is crushed. Chopped straw (IS) is conveyed by conveyor 11 to the trays 12, with which it is guided under the wheels 10 of the chassis 2. At the back of the wheels are followed by scrapers 13 mounted on the chassis, which fill the track with bulk and level the restored soil layer. Mower 14 with a rotary cutting apparatus having three disk levels, after mowing the XM bread mass with mower 3, mows and crushes the IST stubble, which crumbles over the surface of the processed strip. The system of rollers 15 with pneumatic drives 16 provides the creation of a lower water-holding soil layer together with the running wheels along the entire width of the water-holding strip of the VUP, where a is the width of the roller, and b is the width of the running wheels. The seeder 17 carries out post-harvest sowing of crops or forage grasses. Field roller 18 carries out post-sowing compaction of the topsoil.

The advantage of the unit for agricultural work is that the technological process is improved in terms of creating a lower water-holding soil layer and post-sowing compaction of the upper soil layer.
