Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to corn harvesting machines designed to harvest the entire biological yield of maize.

The purpose of the invention is to reduce cleaning losses, increase productivity and improve operating conditions.

FIG. 1 shows a schematic representation of the proposed corn-harvesting console, type

from the side; in fig. 2 - the same, plan view; in fig. 3 - mobile connection

and fixed frame parts between each other.

The maize harvester includes dividers 1, a picking hub 2, mounted on the movable part 3 of the frame pivotally connected to the fixed part 4 of the frame, on which the cutting unit 5 is mounted and the screw 6 behind it for transporting the leaf stem, feeding the device grinder 7, grinder 8 with a silo 9.

A coil auger 10 and a conveyor 11 for supplying cobs to a cob thresher or hate machine (not shown) are mounted at the fixed section 4 of the frame of the coil by the second rollers 2.

The hinged connection of the movable part 3 with the fixed 4 frame is made with the aid of an arm 12 fixed to the fixed part 4 of the frame.

A bracket 12 is provided with a floor pin 13 connected to the movable part 3 of the frame. The trunnion 13 is equipped with rolling bearings 14 of the anti-drive shaft 15, through which the spindle drive is driven through an asterisk 16, their

rolls. Similarly, the movable part 3 of the frame is connected to the fixed 4 and from the opposite end of the frame.

Lifting (lowering) of the movable part 3 of the frame with the crushing rollers 2 is carried out with the help of hydraulic cylinders 17, which are hinged on one side on the fixed part 4 of the frame, and on the other hand on the movable part 3.

The proposed machine works following

sh. in the way

When harvesting tall corn, the movable part 3 of the frame using hydraulic cylinders 17 rotates around the axis of the drive shaft 15 of the crushing rollers 2 by the required amount depending on the height at which the cobs are attached to the corn stalks. When the machine is moving, the corn stalks with dividers 1 are inserted into the pickup department of the second rolls 2, in which the cobs are separated from the stems, after which the cobs are fed by the screw 10 and the conveyor 11 to the picker.

After the removal of the cob, the stems are cut by the cutting unit 5, then by the screw 6 and the feeding device 7 are fed to the chopper 8. The crushed leaf stem mass through the silo 9 enters the means of transport.

When harvesting ordinary corn with the arrangement of the cobs on the stalks at a slight height, i.e. corn with medium or low yield, the movable part of the frame 3 is also rotated by an angle that provides optimum performance of the machine.

Claims (2)

1. CORN HARVESTING MACHINE by ed. St. No. 686663, characterized in that, in order to reduce losses during cleaning, increase productivity and improve operating conditions, the console frame is made of fixed and pivotally connected to it with the possibility of rotation and fixation in the vertical plane of the moving parts, while the picking rollers are mounted on the moving parts, and its rotation axis relative to the fixed part is combined with the axis of the drive shaft of the picking rollers, 2. The prefix on π. 1, characterized in that both parts of the frame are interconnected by hydraulic cylinders.
