Description

The utility model relates to the field of agriculture, in particular to grain harvesters, and is intended for mowing and supplying grain mass to the feeder chamber of the combine.

Known design header combine harvester, ZhU-6 for harvesting grain crops, containing a frame, dividers, auger, cutterbar, feeder house with a conveyor, reel with a mechanism for removal and lifting and manually changing the angle of the rake [EN 2012186, A01D 41/12] .

The disadvantages of this harvester are:

1. The inability to quickly change the angle of inclination of the reel rakes depending on the height of the plants and the degree of lodging of the grain stand, which leads to a decrease in the quality of harvesting.

2. The complexity and laboriousness of manual adjustment of the angle of inclination of the reel rakes, for which it is necessary to stop the harvester, which reduces its productivity and increases the harvesting time.

Known harvester harvester KZS-1218 for harvesting grain crops, containing a frame, a conveyor, a reel with a mechanism for removal and lifting and manually changing the angle of the tines [Operating manual. Self-propelled grain harvester KZS-1218 "PALESSE GS12" KZK-120000000 IE, 2013].

The disadvantages of this harvester are also:

1. The inability to quickly change the angle of inclination of the reel rakes depending on the height of the plants and the degree of lodging of the grain stand, which leads to a decrease in the quality of harvesting.

2. The complexity and laboriousness of manual adjustment of the angle of inclination of the reel rakes, for which it is necessary to stop the harvester, which reduces its productivity and increases the harvesting time.

The closest in technical essence to the claimed utility model is a cutting device for a harvester, in particular for a combine harvester [RU 2631685, A01D 41/14], containing a knife cutting device for mowing the harvested crop and a feeder that transports the beveled harvested crop from the knife cutting device to feed it to the processing device, in particular to the threshing unit, and a recording device is provided for determining at least the height (H) of the harvested crop before mowing as a parameter of the harvested crop, characterized according to claim 8 of the formula in that the cutting the apparatus comprises a rotatably driven reel, wherein the control unit is configured to adjust the reel rotation speed and/or the position of the reel relative to the main frame of the cutterbar depending on the obtained parameter (H) of the harvested crop.

The disadvantages of this cutting device are:

1. The complexity of the operational adjustment of the angle of inclination of the reel rakes, depending on the height of the plants and the degree of lodging of the grain stand, which leads to a decrease in the quality of harvesting.

2. To perform manual adjustment of the reel tine angle, it is required to stop the harvester, which reduces its productivity and increases harvesting time.

The objective of the utility model is to improve the quality of harvesting, reduce the complexity of adjustment and increase the productivity of the combine.

The problem is solved due to the fact that the header of the combine harvester, consisting of a frame on which are installed: a cutting device, an auger, a reel with beams fixed to a separate axis, at the outer ends of which rakes are installed with the possibility of changing the angle of inclination, an optoelectric sensor, an electric the output of which is connected to the control unit, is additionally equipped with a hydraulic cylinder mounted on the frame, which is connected by a rod to a separate tine axis and connected to the control unit.

New significant features:

1. An additional hydraulic cylinder is installed on the header frame of the combine harvester.

2. The hydraulic cylinder is connected by a rod to a separate tine arm axis.

3. The hydraulic cylinder is connected to the control box.

The listed new essential features, together with the known ones, make it possible to obtain a technical result in all cases covered by the scope of legal protection.

Technical result

The technical result consists in improving the quality of harvesting, reducing the complexity of adjustment and increasing the productivity of the combine due to the fact that the header of the combine harvester is additionally equipped with a hydraulic cylinder mounted on the frame, which is connected by a rod to a separate tine axis and connected to the control unit.

The figure schematically shows the header of a combine harvester.

Header of a combine harvester, consisting of a frame 1, on which a cutting device 2, an auger 3, a reel 4 with beams 5 fixed to a separate axle 6 are installed, at the outer ends of which rakes 7 are installed with the possibility of changing the angle of inclination, an optoelectric sensor 8, for example, a video camera, the electrical output of which is connected to the control unit 9. On the frame 1 of the harvester, a hydraulic cylinder 10 is additionally installed, the rod 11 of which is connected to a separate axis 6 of the tine arm 7. The hydraulic cylinder 10 is connected to the control unit 9.

Harvester combine harvester works as follows. When the combine moves at a speed V and the reel 4 rotates ω _m , the tine 7 captures the plants, holds them during the cut with the cutter 2 and moves the cut plants to the auger 3. The rotating ω _w auger 3 transports the cut plants for further processing, i.e. threshing. An optoelectric sensor 8, for example, a video camera, fixes the height H of the stalk and in case of a laid down harvested mass, at low values of H, the reel goes down and, at the signal of the control unit 9, the hydraulic cylinder 10 with the rod 11 rotates the tines 7, changing the angle of their entry into the grain mass, for lifting of fallen plants and bringing them to the cutting unit 2. Operational control and management of the angle of inclination of the tine arm 7 of the reel 4 makes it possible to reduce crop losses when harvesting undersized and lodged plants by lifting the fallen stems and bringing them to the cutting unit 2.

Claims (1)

Header of a combine harvester, consisting of a frame on which are installed: a cutting unit, an auger, a reel with beams fixed to a separate axis, at the outer ends of which rakes are installed with the ability to change the angle of inclination, an optoelectric sensor, the electrical output of which is connected to the control unit, which differs the fact that the harvester is equipped with a hydraulic cylinder mounted on the frame, which is connected by a rod to a separate tine axis and connected to the control unit.
