Description

eleven

The invention relates to agriculture and can be used for harvesting corn.

The purpose of the invention is to improve the productivity of harvesting by improving the visibility of the harvesting of stalks and working bodies of the machine.

Fig. 1 schematically shows a corn-harvesting machine Do1 for carrying out the proposed method for harvesting maize, top view; 2 - the same, pid from the side; on fig.Z - section aa in figure 1.

The maize harvester contains a frame 1 on which the header 2 is mounted. The header 2 has a pickup unit 3, as well as two cutting units — the lower 4, mounted under the night picker 3 and cutting off the lower part of the stem, and the upper 5, located to the side of the lower one and intended to cut the upper part of the stem of the stalk of the ear. Behind the lower cutting appliance D, a stalk-transporting body 6 is installed, which is, for example, in the form of a screw. Behind the pickup unit, apparatus 3, there is a conveyor of 7 ears. The upper cutting apparatus 5 is provided with a transporting body 8, which can be made screwed and installed in such a way that its unloading end is located above the bleaching body and the transporting body 6, i.e. above the leafy mass transfer zone. 6. Under the unloading end of the transporting body 8, a slope board 9 can be installed to move the cut tops of the stems into the transporting body 6. The upper cutting apparatus 5 is installed with the possibility of adjusting its position in the vertical plane depending on the height of the cobs on the stalks. To reduce the overall width of the machine in the transport position, the cutting unit 5 is rotatably mounted on the vertical axis 10. The outer horse of the unit 5 can be supported on the self-adjusting wheel 1 1 by the height adjustment mechanism 12 of the wheel, but can be connected to the l: zhki 13 whose length is made

51820

adjustable depending on the height of the cutting apparatus 5.

To prevent the cutting device from turning 5 around the axis 10, a locking device 14 is provided.

 chopping up of leaves A grinding device 15 is provided, mounted behind the stalk transporting body 6,

10a for discharging the ground mass into the vehicle - the discharge conveyor 16.

The harvesting of corn by the proposed method using a corn harvester is carried out as follows.

During the first pass of the machine, the upper parts of the stems of the plants located to the side of the

20 maschiny. For this, the upper cutting apparatus 5 of the machine is transferred from the transport position to the working position, is stopped in this position by the device 14 and is set to a height

25 arrangement of the upper end of the cobs. In this case, the length of the stretch 13 or the height of the wheel 1.1 is adjusted. During the first pass of the machine, the tops of the stems are cut off by the apparatus 5 and the transporting 30 body 8 is fed to the transporting body 6 and then to the grinding machine 15. After the first breeze is completed and the upper part of the stems is cut, the harvesting machine is directed in rows (Fig. 1). In this case, cutting of the lower part of the stems and at the same time cutting the upper part of the stems of the plants located on the side of the harvesting machine is carried out. The cobs are separated by the corn picker 3 and then conveyor 7 is fed for further processing (cleaning from wrappers or threshing). The stalks that are drawn by the chopping device 3 are cut off by the lower cutting device 4, captured by the catching-transporting body 6.

and is fed to the grinding apparatus 15 by them. The ground mass by the conveyor 16 is discharged into a vehicle (not shown). Simultaneously with these operations, the upper cutting apparatus 5 cuts off the apical part of the stem, which is transported by the transporting body 8 to the transporting 55 org-en 6 and then to the crushing unit 15.

Since cutting the lower parts of the stems with each pass of the machine.

starting from the second pass, carried out after preliminary cutting of the upper parts by the cutting apparatus 5, located to the side of the lower one, the view of the retractable rows and the machine’s working parts is improved, which allows increasing its working speed and, consequently, producing

cleaning performance. Transportation of the cut tops of the stems with their submission to the grinding apparatus increases the collection of leafy stalks. In addition, improved visibility reduces damage by the working bodies of the machine to adjacent rows and reduces the loss of the ears and leafy mass.
