Abstract

The invention can be used in agriculture for harvesting grain and seed of grass with drying of the mass in rolls and provides an improvement in the quality of grain and a reduction in its losses during harvesting in adverse weather conditions. The plants are mowed and laid in rolls by the header. After drying the upper half of the rolls, this half is picked up and threshed with a combine with a pick-up. The resulting threshing straw is placed on the stubble next to the lower half of the rolls, for which an inclined tilting board is installed under the straw unloader. Then the mass of the lower half of the rolls is turned over with a tedder on the laid straw mass and after final drying they are picked up and threshed. 3 il.

The invention relates to agriculture and can be used for harvesting grain and grass seed with mass drying in wels.

The purpose of the invention is to improve the quality of the grain and reduce its losses during harvesting in adverse weather conditions.

Figure 1 shows the flow chart of the proposed method; 2 is a side view of a combine harvester for carrying out the method; on fig.Z - the same, rear view.

Means for carrying out the method include a roller header 1, a tedder 2, and a harvester 3 with a pick-up 4 and a board 5. located under the unloader 6 of the straw mass of the combine. The board 5 is inclined towards the lower half of the rolls.

The method of harvesting grass seeds is carried out as follows.

At the beginning, the seed grass 7 is mowed and placed in the rolls 8 with a roller header 1. After the upper half of the rolls has dried, it is picked up and threshed with a combine 3. The pick-up 4 is raised to the appropriate height. The straw mass 9, obtained as a result of threshing, combines 3 is laid on the stubble next to the lower half of the rolls 8 left. The straw 9 is directed towards the lower half of the roll 8 by an inclined board 5. Thereafter, the lower (non-crushed) half of the rolls 8 dl Drying overturn with the help of a tedder 2 on the laid straw mass 9 with the formation of a common roll 10. After drying the lower half of the rolls 8 they are picked up and threshed with a harvester 3 with a pick-up.

about

When picking up the dried lower half of the rolls 8, it is advisable to pick up a small part of the straw downstream in the roll 10, which makes it impossible to remain in it unmilled seed. However, the lower half of the rolls 8 can be selected with or without the whole straw mass.

This invention allows to improve the quality and reduce the loss of seeds when harvesting in conditions of high humidity, since the selection and threshing of the upper half of the rolls are performed immediately after they are dried, and then the lower half of the rolls are dried in better conditions (straw masses). not on wet ground).
