Description

The invention relates to agricultural machinery and can be used in the development of devices for post-harvest processing of breeding seeds of grain and leguminous crops, as well as grass seeds and black onion.

Known selection thresher LD 350 WINTERSTEIGER (Austria), containing a loading chute, threshing chamber, unloading chamber, air separation channel, sedimentary chamber, fan, trays for collecting separated fractions [WINTERSTEIGER AG [Electronic resource]. - Official website: https://www.wintersteiger.com/en/PROPETATION- AND- RESEARCHES/Products/Assortment/Laboratory equipment/69-LD-350].

The known device showed an insufficiently high level of seed treatment. After threshing plant bunches, unfinished seeds and seeds with awns remain. After processing in a pneumatic separation channel, the purified material requires additional processing on separate separating machines. The absence and inability to install exhaust air purification devices after the fan leads to increased dustiness of the premises.

An object of the invention is to increase the productivity and efficiency of post-harvest processing of breeding material.

The technical task is achieved by the fact that in the threshing and separating device, including a loading chute, a threshing chamber, an unloading chamber, a pneumatic separating channel, a sedimentation chamber, a fan, trays for collecting separated fractions, according to the invention, it is equipped with a separator and an exhaust air purification device, a pneumatic separating channel divided into cleaning and sorting sections, an inclined support grid is placed, and the sedimentation chamber is divided into sections of the selected impurities and sorted seeds.

The invention is illustrated in the drawing, which shows the threshing and separating device of the breeding material.

The device comprises a loading tray 1, a threshing chamber 2, an unloading chamber 3, a pneumatic separation channel 4, a sedimentation chamber 5, a fan 6, trays for collecting separated fractions 7, an osteo separator 8, an inclined support grid 9, a cleaning 10 and a sorting 11 section of the pneumatic separation channel 4, section 12 for the selected impurities and section 13 of the sorted seeds of the sedimentary chamber 4, the exhaust air purification device 14.

Threshing-separating device operates as follows.

The selection material, consisting of a certain number of cut ears of plants, is fed by a beam to the loading tray 1, from where it enters the threshing chamber 2, where they are threshed. After threshing, the plant stems enter the unloading chamber 3, threshed the seeds by gravity into the osseootdelitel 8 to remove the awns and hammer, and then into the pneumatic separation channel 5, where the material being processed, moving down the inclined support grid 9, under the influence of a vertically ascending air flow, driven by the fan 6, is subjected to cleaning and sorting. In the cleaning section 10 of the air separation channel 4, impurities are released: floor and straw. Sorting and seedless seeds are distinguished in sorting section 11. The separated impurities and sorted seeds are carried out by air to the respective sections 12 and 13 of the sedimentation chamber 5. The exhaust air after the fan 6 is cleaned in the device 14. The separated fractions are collected in trays 7.

The installation of the separator 8, as well as the inclined support grid 9 in the pneumatic separation channel 4 and its separation into the cleaning 10 and sorting sections 11 increases the productivity and efficiency of processing the selection material, since as a result of processing the selection material on such a threshing-separating device, seeds with high germination capacity are obtained and germination energy, which do not require further processing.

The installation of an exhaust air purification device allows the threshing and separating device to be operated in enclosed spaces, in particular in the laboratory rooms of breeders.
