Description

The most common combine harvesters for corn harvesting with the separation of the cob and chopping the leafy mass are complex in design and cannot be used for harvesting crops with broken row spacing, as well as for harvesting corn and other crops for silage with continuous sowing.

The proposed harvester is distinguished by the combined use of the pick-up rollers, the knife drum, the crushing machine, and the stem catcher, their rollers, mounted at the exit end of the coil conveyor.

FIG. 1 shows a side view of the combine; in fig. 2-view of the combine from the top.

The harvester consists of a reaper 1, a reel 2, a conveyor 3, a receiving beater 4 with a feed roller 5, a knife drum 6 and an unloading conveyor 7. The open-end rollers 8 and 9 are installed between the receiving beater and the knife drum.

On the JO plate, the valve 11 is hinged forwards, which, when the cobs are separated from the stems, opens a door to pass the cobs to the conveyor 12.

A stalk is mounted on the end of the conveyor to trap short stems. 13 rollers are chopped. The cobs are crushed by a crushing machine 14, which is installed instead of the stalk rollers.

The upper crushing roller is provided with springs 15 and 16. Przzhins are separated by a gasket 17, squeezing, it has one spring when the cobs are torn off from the stalks under the action of an adjusting screw 18.

When using the crushing rollers to feed the entire retractable mass into the knife drum, both prul-: squeeze with a smaller force with the help of the pressure nut 19. Mechanisms of the combine floor drive drive from the tractor's power take-off shaft.

The technological process of the combine harvesting corn is as follows.

When harvesting corn with the grinding of all plant mass, the corn stalks cut from the conveyor 3 are cut by the cutting machine 3 with the receiving beater 4 and the feeding roller 5 to the picking roller 8 and 9.

The vegetable mass is crushed with a knife drum and falls onto a horizontal belt of the discharge conveyor 7, which feeds it onto the inclined conveyor 20. At this time, the valve 11, which takes a horizontal position, closes the hatch of the cobs, which ensures the supply of all the plant mass to the knife drum.

For harvesting the corn with the separation of the cobs from the stems, the valve // is placed in the vertical position. The clamping force of the upper crushing roller to the lower one is increased by means of a screw 18.

The stems supplied by the receiving beater and the threading roller are guided along the plate 10 to the night-breaking rollers. During harvesting of corn, in milky-wax ripeness, the cobs, separated from the stems, fall onto the conveyor 12, and then into the crushing machine 14 and onto the conveyor 21, from which, when crushed, enter the trolley 22. When harvesting the cobs in full ripeness, the crushing machine 14 is replaced stalk rolls 13.
