The invention relates to agriculture, in particular to methods of harvesting grain crops.

The purpose of the invention is to reduce grain losses by reducing the duration of harvesting, reducing labor costs and traumatizing the soil.

According to the harvesting method, when the wax ripeness of the grain has occurred, the cutter will mow the plants with stripes, leaving unmowed strips between them. The grain mass from the mowed strips is placed in the rolls, placed next to the non-bevelled strips, the width of which is chosen to be less than the header’s grip on the width of the rolls. The mowing and threshing of plants of unmowed bands are subsequently carried out together with the selection and threshing of rolls.

Example. At the onset of the wax ripeness of the harvested breads by the header, for example, ЖВН-b, the grain mass is cut by strips of width, for example, in one grab of the header, i.e. 6 m, leaving unmowed strips between them. In this case, the rolls are positioned on the edge of the mowed strips, i.e., next to the non-beveled strips, the width of each of which is equal to that of the combine harvester minus the width of the rolls adjacent to the non-beveled strip. For example, when the header width of the combine is 6 m and the width of a strip with a roller adjacent to an open strip, 2 m width of a non-skimmed strip is set to 4 m. One roll on one side or two rollers one on each side can be placed next to a non-skidding strip. sides, which depends on the width of the strips mown into rolls and on the design of the header used.

After drying of the rolls and full ripening of the grain, left and unmowed strips produce a selection and threshing of the rolls together with the mowing and threshing of the left strips. In this case, the selection of the rolls is carried out by cutting the stubble under them simultaneously with the cutting of the left strips, i.e., in one pickup of the combine header. For this, the rolls in the initially mowed strips are placed on the upper stubble, which is obtained by appropriately tilting the cutting unit of the header to the surface of the floor. For example, when harvesting wheat, plant height of 1 m, the cutting height at roll locations is taken to be 20-30 cm, lowering it to the opposite edge of the swath to 10-12 cm. Stubble under the rolls and left strips are mowed at a height of 10-12 cm from the soil surface.

To ensure that the roll is fed to the header of the combine, when cutting the stubble under it, the radius of the

part of the combine reel, which is located above the roll.

A variant of the selection of rolls is possible when n, and one part of the header of the combine is controlled by a pick-up for the selection of rolls, and on the other part is a cutting apparatus for cutting the plants in the left uncompleted strips.

The cut and picked-up grain weight of the trans U, which arrived at the combine header, is transported to the threshing machine by the porter of the combine.

Due to the mowing of the grain mass by the loses, it is concentrated around the unmowed bands, which allows for more

to fully load the harvester, which further threshes, and thereby reduce the time of harvest and, consequently, the loss of grain.

When mowing the mass in one or two strips of the header, the headers are provided with known headers without additional conversion, laying the rolls on the edge of the mowing strips next to the non-mowing strips. If you mow stripes in width, for example, in three

capture header, it will increase the time and cost of selection in the further formed while in the middle of the strip of the roll, which placement at the edge of the uncut mowers of the famous header is impossible.

It is advisable to make cutting into rolls with strips in one grab of the header with slight contamination of the harvested grain, and mowing with two grabs of the header - with large debris. The width of the mowed strips in rolls is set

so that the dried bread mass coming from the rolls from the rolls is mixed with the grain of the grain later than the mowed left strips, reduces the total moisture of the bread mass and thus provides an improved

lacability
