Abstract

FIELD: agriculture, in particular, process for harvesting of cereal crops such as barley.

SUBSTANCE: method involves mowing cereal crop at its full maturity stage in direction opposite to direction of wilting or lodgeability of cereal crop or at an acute angle to said direction; mowing cereal crop with following threshing thereof.

EFFECT: reduced grain loss, which may occur as a result of engagement thereof with working tools, owing to arrangement of ears above header part during cutting of cereal crops.

Description

The invention relates to agriculture, in particular to methods for harvesting crops, such as barley, and can be used to develop new methods for harvesting crops.

A known method of harvesting grain, described in the book Vavilov P.P. and other Crop production, M., Kolos, 1979, S.50-51. At the moment of full ripeness, one or another grain crop is mowed by a combine harvester and threshed.

A significant disadvantage of this method is the large loss of grain from interaction with the working bodies of the harvester.

There is also known a method of harvesting barley according to patent RU 2057428 B.10, 04/10/96, in which it is proposed to remove barley by mowing drooping plants perpendicular to the direction of drooping of the ears.

A significant disadvantage of this method are the large losses from interaction with the working bodies of the header, because lateral orientation of plants leads to the fact that part of the plants falls when cutting past the cutting apparatus and is again subjected to cutting, which increases the already significant loss of grain, and now also cut ears.

The objective of the invention is to improve the quality of harvesting cereals, such as barley, to reduce grain losses and to exclude excessive cutting of ears, and this is possible due to the fact that the mowing of crops in the phase of full ripeness when the ears are drooping should be carried out in the direction opposite to the direction of growing or laying down of the ears culture or at an acute angle to bedding, followed by threshing.

A new significant feature of the method

- mow crops, for example barley, in the direction opposite to the direction of drooping or laying down of the ears of the mowed crop or at an acute angle to this direction.

The specified new essential feature, together with the known ones, is necessary and sufficient to achieve a technical result in all cases to which the requested amount of legal protection applies.

An example implementation of the method. First, determine the direction where most plants were laid down, then mow the field, beat the pens and then mow the bulk of the grain crop, for example barley, in the opposite direction to the main bedding or drooping of the ears or at an acute angle to the direction of bedding of the ears.

The proposed method of harvesting grain crops, such as barley, allows to reduce grain losses and how to interact with the working bodies, because Now the ears drooping immediately upon the oncoming movement of the machine fall on the header of the header and are cut off, already above the header, and due to the fact that the direction of movement of the machine is directly opposite, there will now be no side interactions with the tilted ears.

The use of the alternative: “or at an acute angle to the direction of bedding of the mowed crop” does not change the technical result obtained - reducing grain losses by eliminating re-cutting of ears and reducing side interactions of the working bodies of the header with ears.

Claims (1)

A method of harvesting grain crops, for example barley, including mowing and threshing in the full ripeness phase, characterized in that the mowing is performed in the opposite direction to the drooping or littering of the ears of grain, or at an acute angle to this direction.
