Description

Corn harvesters are known for working between the rows of different widths. It is also known the use of combines disk cutting apparatus and grinding rollers.

A major disadvantage of these corn harvesters is the impossibility of arranging the working streams when harvesting corn with inter-row spacing in the range of 700-1200 mm. This circumstance limits the choice of the most appropriate aisles. A serious disadvantage of corn harvesters is also the inability of them to harvest hybrid corn.

A distinctive feature of the described combine is that the stem supply chains, the cutting unit, the pickup and chopping rollers are made for each row as separate blocks, according to the number of rows, with a single kinematic link and mounted on the wheels of the worm pairs, control which rendered to the place of control of the unit. Such an implementation of the mechanisms of the combine provides the possibility of harvesting corn with different aisles.

There is a tendency to plant maize in the form of two-line belt crops with inter-spacing between 1400 and 2100 mm tapes. For harvesting such crops, two-row harvesters with frontal arrangement of working bodies are necessary.

The drawing shows a view of the combine side.

The proposed combine is a two-row mounted machine with a frontal arrangement of the working bodies. It is intended for harvesting ripe corn, as well as corn in the stage of wax ripeness of grain, sown with different aisles. In all cases, the combine provides the separation of the ears and the grinding of corn stalks. The harvester consists of a disk cutting unit /, stem-feeding conveyors 2, tilt 3 stems, rollers 4 for separation of the cobs, rollers 5 FOR chopping the stems, conveyor 6 cobs, conveyor 7 of the crushed stems and mechanism 8 for adjusting the working streams consisting of a worm and a worm with a turning circle.

No. 116178-2 -

The combine works as follows.

The corn stalks are clamped by the feed chains, cut off by the idler disk of the cutting unit and fed (by forward) into the crushing rollers.

When the stems are pushed into the gap between the rollers, the cobs are torn off, fall onto the cob conveyor and fed into the container attached to the rear of the tractor. The stems being pulled by the chopping rollers enter the rollers to chop the stalks, the latter are crushed into small fractions and fed by means of a conveyor of shredded stalks to the auto-trunk. The main advantages of the proposed combine are: better maneuverability, the lack of need for preliminary obkosy and prokosah sites, the possibility of selective cleaning and other advantages inherent in mounted machines with frontal location of the working bodies.

On the combine, it is possible to change the arrangement of the working streams of the combine to different aisles, within 700-1300 mm, by setting and adjusting with the mechanism 8 the position of each stream during operation of the tractor operator.

The conventional cutting apparatus driven by a crank mechanism is replaced by a disc cutting unit driven by chains of steeple-feed conveyors.

As a result of the combination of the main working bodies (cutting apparatus, stem-feed chains, crush and crushing rollers) as a common unit, the working streams are arranged in a wide range, thus creating the possibility of using a combine for harvesting corn with different inter-row spacings.

Subject invention

Claims (2)

1. A hinged corn cob harvester, characterized in that, in order to be able to harvest maize with different aisles, the stem supply chains, the cutting unit, the crushing and grinding rollers are made for each row as separate blocks, according to the number of rows, with a single kinematic connection and attached to the wheels of worm pairs, the control of which is transferred to the place of control of the unit. 2. A combine according to claim 1, characterized in that the disk cutting apparatus is driven by chains of the steeple-release conveyors.
