Description

 The invention relates to agricultural machinery, in particular, to combines for harvesting seeds of easily sowing agricultural plants, for example, testes of herbs and other unevenly ripening crops.

 A known combine for harvesting seeds of easily sowing agricultural plants [1] containing a reaper with a reel, a cutting apparatus and an auger, an inclined chamber, a straw separator installed in the housing, cleaning, a beater and a swather, while the transporting elements of the reel and auger are equipped with elastic overlays, and the beater is finger-shaped and equipped with a bar grill.

 This combine does not provide for the capture of seeds knocked out by a reel. Also known is a combine harvester for harvesting seeds of easily sowing agricultural plants [2] containing a header with a cutting apparatus, reel and auger, an inclined chamber, a straw separator installed in the housing, cleaning, a beater and a swather, while the transporting elements of the reel and auger are equipped with elastic pads, the beater is finger-shaped and equipped with a bar grill having elastic rods fixed on one side at the ends of its rods, and on the other hand on the combine body.

 This combine is characterized by the same drawback. The technical result of the invention is to reduce losses due to the capture of seeds knocked out by a reel on a special platform, as well as to reduce the cutting height of plants by giving the cutting apparatus the ability to improve copying of the soil relief.

 The technical result is achieved by the fact that the combine for harvesting seeds of easily sowing agricultural plants, containing a header with a reel, a cutting device and an auger, an inclined chamber, a straw separator installed in the housing, cleaning, a beater and a swather, according to the invention is additionally equipped with a special platform mounted on support wheels, articulated connected on one side to the bottom of the header, and the cutting apparatus is mounted on the opposite side of the platform.

 The drawing shows a diagram of a harvester for harvesting seeds of easily sowing agricultural plants.

 The harvester contains a header 1 with a reel 2 and a screw 3, an inclined chamber 4 with a conveyor 5 and a grill 6 installed in the case of a beater 7, a straw separator 8, cleaning 9, a screw 10, an elevator 11, a seed hopper 12 and a swather 13.

 The harvester is additionally equipped with a special platform 15 mounted on the support wheels 14, pivotally connected on one side to the bottom of the header 1. A cutting apparatus 16 is fixed on the opposite side of the platform 15.

 The harvester for harvesting easily sowing agricultural plants works as follows.

 Agricultural plants to be harvested by reel 2 are fed to the cutting apparatus 16 and, after cutting, are fed by the reel along the platform to the screw 3. In this case, the reel 2 is knocked out of a significant part of the most mature seeds that fall on the platform 15 and are fed with the rest of the cut mass to the screw 3 of the header 1. Next, the plant mass, together with the seeds driven by the reel 2, is fed by the screw 3 into the inclined chamber 4, where, due to the interaction of the strips of the conveyor 5 and the strips of the grate 6, yes flaxseed seed. After the inclined chamber 4, the plant mass falls onto the straw separator 8, where free seeds are separated, and the rest of the plant mass, together with the immature seeds, falls on the swather 13 and is formed into a swath. Free seeds are cleaned 9 and with the help of a screw 10 and elevator 11 are fed into the hopper 12.

 The platform 15 mounted on the support wheels 14 and pivotally connected to the header 1, improves the conditions for copying the topography of the soil and reduce the height of the cut.

 Combine research trials have shown that the reduction in seed loss is 5-9.5% reduction in cutting height of harvested crops to 5 cm.
