RU97239U1 - STUBBLE SEEDER WITH COMBINED ROTARY WORKING BODY - Google Patents

Abstract

 A stubble seeder with a combined rotary working body, comprising a frame, a milling section closed by a protective cover, fertilizer and seed machines, respectively, with a fertilizer line and a seed distributor, a packer roller and a zagortok, characterized in that, in order to improve the quality and reduce the energy consumption of soil cultivation, disks with active and passive drives are installed on the shaft of the rotary working body, on which the cutting knives are fixed.

Description

The invention relates to agricultural machinery, namely to stubble seeders with combined working bodies.

The known design of a combined tillage implement containing a main frame, a seed hopper, loosening working bodies, each of which has a coulter, and a packer roller, as well as an additional frame and leveler (accession No. 1064881, publ. 07.01.84) .

A disadvantage of the known tool is the high energy intensity of tillage, since the working bodies have a constant forced drive.

Known combined unit for tillage and sowing, containing a frame with support wheels, on which is mounted a milling drum, closed by a casing with a shield-leveler. A shoe with a coulter is installed behind the milling drum (station number 1507221, publ. 15.09.89).

The disadvantage of this unit is the insufficiently high quality of soil cultivation, as well as increased energy costs for its processing.

Known combined unit for tillage and sowing, containing a frame of cultivators, a milling drum with a leveling flap, a packer roller (av.St-in No. 1516020, publ. 23.10.89).

The disadvantage of this unit is the low quality of the soil and the high energy consumption of the milling process.

Known is a combined machine for tillage and sowing, containing a milling section, a sowing unit, a distributor, packer rollers (station number 1658848, publ. 30.06.89).

The disadvantage of this unit is the low quality of tillage.

The purpose of the invention is improving the quality and reducing the energy intensity of soil cultivation.

This goal is achieved due to the fact that passive knives cut the turf in a vertical plane, and active knives intensively crush it, reducing energy consumption for separation of chips from the turf layer.

Figure 1 shows a stubble seeder with a combined rotary working body; figure 2 - rotary working body with a rolling roller; figure 3 - Section aa in figure 2.

The stubble seeder contains a frame 1, a hopper 2 for seeds, a hopper 3 for fertilizers, a rotary working body 4 and a linkage 5 for lifting it (Fig. 1), a metering device (not shown) and seed tubes (not shown), a hydraulic motor 6, an anchor opener 7 and packer roller 8 (figure 2). On the shaft 20 of the rotary working body 4, closed from above by a casing 9, working sleeves 13 are installed (Fig. 3). Between themselves, the working sleeves 13 are separated by spacer sleeves 14, which are also fixed against axial displacement of the bearings 21 of the hub 15. The knives 16 of the active working body are mounted on the disk 17, which is welded to the working sleeve 13. The knives 12 of the passive working body are mounted on the disk 11, which is welded to the hub 15. The shaft 20 is installed in the bearing units 19 on the frame 10.

Stubble seeder operates as follows.

When the seeder is moving, the combined rotary working body 4, driven by the hydraulic motor 6 through the gear transmission with an asterisk 18, processes the soil with strips of the required width to a given depth. Grass seeds are fed by seed meters through the seed tubes to the seed guides and laid in the soil to a predetermined depth. The soil in the strips is compacted by a rolling roller 8. Improving the quality of soil cultivation and sowing seeds is ensured by the fact that passive knives 12 cut the turf in a vertical plane, and active knives 16 intensively crush it. The knives 12 mounted on the disks 11 of the rotary organ cut the sod layer in the zones of the extreme points of the blades. Due to this, the energy consumption for the separation of chips from the layer of turf is reduced and the quality of processing is improved by eliminating the separation of particles of turf from the edges of the grooves. Thus, the main part of the energy consumed by the working body is spent on grinding active slices 16 of the chopped sod tape.
