Abstract

This invention relates to agriculture. The purpose of the invention is to improve the quality of feed. The method of harvesting corn involves cutting off the upper parts of the stems of the stems in the phase of milky-wax ripeness of grain with simultaneous deformation of the slice with a permanent deformation. Then, at full ripeness of the grain, cutting of the lower parts of the stems with the separation of the ears is carried out. The method provides an increase in the yield of fodder units from leafy mass, since the upper parts of the stems are cut off during the period when they contain the greatest amount of substances digested by animals. The silage obtained from the lower parts of the stems is also of high quality. Since the tops of the lower parts of the stems are deformed at the point of cutting, the nutrients and moisture necessary for the growth and ripening of the grain on the cob are prevented from leaving the stems. 2 Il.

Description

The invention relates to the field of agriculture, in particular to methods for harvesting tall stem crops, mainly maize.

The purpose of the invention is to improve the quality of feed.

FIG. 1 shows a device with which the proposed method is carried out; in fig. 2 is a view A of FIG. one.

The device contains a high-clearance energy tool, on which the header 2 is cut with height adjustment for cutting the upper parts of the stems, containing the cutting apparatus 3 and the working body 4, transporting the cut-off upper parts of the stems, for example the screw. Behind the working body 4 there is a chopping-chipper 5, communicated with the hopper 6 for the crushed leafy stem. To ensure deformation of the lower part of the stem in

the cut-off position of the header 2 is equipped with a device installed under the cutting unit 3

7dl deformation The device 7 contains a pair of exciting horizontal stems established with a gap relative to each other, formed by chains

8 with legs 9. Leading asterisks 10 contours are mounted on vertical drive in opposite rotation, opposite to movement of the device, shafts 11 located behind the cutting unit 3. Each asterisk 10 is made integral with the disk 12 in its upper part, and the disk 12 has a larger diameter than asterisk 10. The disks 12 are in contact with their side surfaces 13, the latter can be made grooved. The front parts of the contours are located in front of the cutting apparatus 3 in the middle of the row of plants being processed. The number of deforming devices 7 corresponds to the number of rows processed. Shift Speed

The length of the chains 8 corresponds to the speed of movement of the energy means 1.

Corn harvesting according to the proposed method is carried out as follows.

In the phase of the milky or milky-wax ripeness of the grain, the upper parts of the corn stalks are cut using the described device. For this purpose, the header 2 with the deformers 7 is set at the height of the upper end of the cobs. When energy means 1 is moved along the spacing between chains 8, they move in the opposite direction at the same speed, pick up the upper parts of the stems with paws 9, bring them to the cutting unit 3 and hold them during cutting. The cut-off upper parts of the stems by the screw 4 are transported to the shredding-chipper 5, crushed therein and fed into the hopper 6 for the crushed leaf stem. The tops of the lower parts of the stems are fed by paws 9 of the chains 8 to the disks 12, are captured by the lateral surfaces 13 of the latter and rolled between them. When rolling the tops at the point of the cut, they are deformed (flattened) to permanent deformation, at which the tops remain flattened. This stops the movement of juice, nutrients and

moisture to the plane of the cut and eliminated their draining and leakage from the stem. All nutrients are distributed in the leaves and the remaining lower part of the stem, as well as in the cob, where the grains are poured. Due to this, the formation of the cob receives more nutrients, which contributes to a better filling of the grain. In addition, more nutrients remain in the leaves and stem.

At full technical ripeness, the grains on the cob harvest the lower parts of the stems with the cobs with ordinary corn harvesting machines. The cobs are separated from the stems, and the latter are crushed for food or ensiled.
