RU2529157C1 - Header of grain combine harvester - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: header comprises dividers (4), a cutting unit, a screw (1) and a feed elevator. The screw (1) is made with the shear segments (2) and has left- and right-hand winding direction (3). The screw diameter (1) is comparable with the height of the stems of spiked cereals. The dividers (4) are made in the form of an isosceles triangle. The sides (5) of the dividers (4) comprise a notch (6) which is directed against the direction of the combine motion at an angle smaller than the angle of friction of stems on the steel. The lower side of the dividers (4) is multiple of pitch of segments (2).

EFFECT: prevention of exit of stems from the cutting unit.

Description

The invention relates to the field of agricultural engineering and can be used in the design of reapers of combine harvesters.

Known cutting apparatus for harvesting and grinding wood greens (Pat. 2435364 RF, IPC A01G 23/00. Screw cutting apparatus for harvesting and chopping wood greens / E.I. Maksimov, V.V. Lebedev, I.V. Golubev, I .S. Fedorchenko; applicant and patent holder State Educational Institution of Higher Professional Education “Siberian State Technological University.” - No. 201021426/12; filed May 26, 2010; published December 10, 2011).

The disadvantages of this apparatus include the possibility of slipping plants from a cutting pair.

Closest to the proposed technical solution is the header of the combine harvester containing dividers, cutting apparatus, screw and tilting chamber (Khalansky V.M. Agricultural machines / V.M.Khalansky, I.V. Gorbachev. - M .: KolosS, 2004. - S.310) - a prototype.

The disadvantages include the complexity of the design, which has a large number of drive elements.

These disadvantages are eliminated in the proposed technical solution.

The technical result is to simplify the design of the header of the combine harvester.

The technical result is achieved by the fact that the header of the combine harvester contains dividers, a cutting apparatus, a screw and an inclined chamber, the screw, the diameter of which is commensurate with the height of the stalks of cereal crops, is made with opposing segments and has a left and right direction of winding, and the dividers are made in in the form of an isosceles triangle, the sides of which contain a notch directed against the direction of movement of the combine at an angle less than the angle of friction of the stems on steel, and divide the lower side lei is a multiple of the step of the segments.

This embodiment of the header of the combine harvester has the enhanced property of the prototype - simplification of the design.

When analyzing well-known technical solutions in the art, signs were identified that distinguish the claimed device from the features of the prototype, and therefore they inform the claimed technical solution of the novelty and inventive step.

The essence of the claimed invention is illustrated by drawings.

The figure 1 presents the header of the combine harvester, figure 2 - dividers with segments.

The header of the combine harvester contains a screw 1 (Fig. 1, 2), the diameter of which is commensurate with the height of the stalks of cereal crops, made with opposing segments 2, has a left- and right-hand direction of winding 3, and the dividers 4 are made in the form of an isosceles triangle, the sides 5 of which contain a notch 6, directed against the direction of movement of the combine at an angle less than the angle of friction of the stems on steel, and the lower side 7 of the dividers 4 is a multiple of the step t of segments 2.

The sign “auger, the diameter of which is commensurate with the height of the stalks of cereal crops, is made with opposing segments” ensures that the stems do not fall out of the header.

The sign “auger has left- and right-hand direction of winding” ensures the movement of stems to the center of the header.

The sign "the sides of the dividers contain a notch directed against the direction of movement of the combine at an angle less than the angle of friction of the stems on steel" prevents the stems from leaving the cutting apparatus.

The sign "the lower side of the dividers is a multiple of the step of the segments" provides the supply of stems to the cutting edge of the segments.

The header of the combine harvester works as follows. When the combine is moving, the dividers 4 divide the stems into equal sections, which, due to the notch 6, directed against the direction of movement of the combine at an angle a, smaller than the angle of friction of the stems on steel, move only in one direction to the cutting edge of segments 2. The stems are cut in a cutting pair - "Auger turns-segments". Due to the left and right directions of screw winding, the mass is moved to the center.

The use of the invention in comparison with known devices of a similar purpose allows to simplify the design of the header of the combine harvester.
