Description

 -.

 The invention relates to rural; can be used for combine harvesting technology with a spread of chopped straw and chaff in the field as an organic fertilizer or mulch. The purpose of the invention is to reduce the cost of processing fields by localizing weed germination.

FIG. Figure 1 shows the device with which the method of harvesting the non-grain part of the cereal crop, hung on the tail part of the combine, is cut, side view .; in fig. 2 - chaff with weed seeds, laid in a groove, top view; in fig. 3 chaff bedding with weed seeds in a groove, rear view.

The device with which the method of harvesting the non-grain part of the cereal crops harvest is carried out consists of the chopping drum 1, the shearing device 2, the spreader 3 for chopped straw, equipped with curvilinear guides, the pitched board 4, the screw 5, the chimneys 6. Figure 6 can be equipped with a pneumatic pipeline 7. All working parts of the device are mounted in a housing 8 mounted on the tail end of the combine 9. The chopping drum in the lower part is enclosed in a guide casing 10. Firewood 6 is enclosed on a casing 11 which at the bottom of the area A-B is provided with a hatch 12 for laying on soil chaff USI continuous ribbon. Fireballs 6 and, consequently, the hatch 12 are located in the plane 13 of the right direction

the right wheel of the combine over the track from

wheels.

The harvester, on which the device is hung, contains a keyboard straw walker with 14 and polisher 15. A groove 17 in the soil is intended for laying the floor 16.

The method of harvesting the non-grain part of the cereal crops harvest is carried out as follows. The straw walker 14 of the keys is picked up by the knives of the chopping drum 1, crushed by the shearing device 2, and along the guide casing 10, the knives of the drum are thrown onto the curved guides of the spreader 3, with which the chopped straw is evenly spread around the field.

The floor 16, with weed seeds in it, with a puff shaker 15, is directed to the auger.

6, from where, due to the firewood effect, it enters the hatch 12, where it narrows into a stream with a width equal to the width of the hatch, for example, to 40-50 cm. wheel of the combine or other similar means. The formed, constricted mass flow of the chaff with weed seeds is guided and placed in the groove 17 formed. ts votrom- beyond the groove.
