    The invention relates to the field of agricultural engineering, in particular to combine harvesters. A combine harvester comprising a header, an inclined chamber and a threshing apparatus, containing a cylindrical casing with guiding ribs on the inner surface, the lower part of which is equipped with a squeezer in the threshing zone and a grille in the separation zone, and a rotor mounted inside the casing linear, parallel to the longitudinal axis of the rotor, corrugated whips, equipped with an impeller 1. Its disadvantage is clogging of the casing with a stalked mass of agricultural culture. The goal of isobodeni is the exclusion of stalked mass of an agricultural crop for the beating of the shell. This goal is achieved by the fact that the rotor is made in the form of a hollow cylinder, on the surface of which, in the threshing zone, are fixed spiral corrugated whips connected to straight corrugated whips fixed in the separation zone. Straight grooved front pests are usually included in the threshing zone. Straight and spiral corrugated whips can be placed on the surface of the rotor at a distance. 120 in an arc, and each of the spiral corrugated scourges covers the surface of the rotor in an arc 120. The front part of the rotor is most often made in the form of a truncated cone, facing a large base to its output end. FIG. 1 shows a straight-through combine harvester, side view; in fig. 2 - the same, front view without a casing; in fig. 3 - the same, front view without the front wall of the casing. The continuous combine harvester 1 comprises a housing 2 having vertical side walls 3 supported on two driving 4 wheels mounted in front and having a relatively large diameter, and on two rear 5 controlled wheels. In addition, the combine contains a platform with cab 6 for the driver, header 7, inclined; chamber 8, grain conveyor 9 and engine 10 of housing 2. The threshing machine contains a cylindrical casing 11, in which a hollow cylindrical mouth 12 is installed. replen impeller 13 spiral type. The harvester also includes a blower 14, a second cleaning screw 15 leading to a grain conveyor 9, and an enormous 16 nicks located in the lower section 17 of the housing under the housing 2. In addition, in the housing 2 under the cylindrical housing 11 there is a screw 18 conveyor for receiving the threshed and a separated grain with a concave 19 and a lattice 20 and baking it on a 21-sieve. The latter reciprocates and the grain and waste are fed to the sieve 22, installed under the sieve 21, and also reciprocating to separate the grain from the waste, resulting in the grain passing through the sieve and entering the second cleaning, 15 and the waste is shifted back and is fed to the 16 head screw. Blower 14 creates airflow over sieve 21 and sieve 22 to remove the tank. Clean grain by screw 15 and transporter 9 is fed to the bunker, then as waste is returned to the casing 11 by means of a conveyor (not shown). An end beater 23 installed under the rear end of the casing 11 prepares: the straw to be removed from the rear of the combine, as shown on the right in FIG. 1. The cylindrical casing 11 is installed along the longitudinal axis of the combine 1, the front part of it has the shape of a truncated cone and forms a funnel-shaped entrance / through which the chat stub mass is fed from the tapping chamber 8 in the form of a wide strip, tapers and enters the rest of the casing for threshing and dividing. The blades of the impeller 13 are located quite close to the inner surface of the truncated cone in front of its part 24 of the casing 11. The longitudinal span of the concave 1 forms the threshing zone, and the extended span of the lattice 20 is the separation zone. Straw and other waste are removed through an opening 25 made in the lower part of the rear end of the casing 11. At the upper part of the inner surface of the casing 11 several spiral guide ribs 26 are fixed, which together with the rotor 12 serve to direct the stalked mass in the axial direction and back through the annular cavity between the casing 11 and the rotor 12, extending from the front part 24 to the hole 25 .. The ribs 26 can be not only spiral, arranged along the entire length of the casing 11, but also annular or absent oats in the threshing zone. At the rear end of the casing 11, an enlarged diamatr 27 is formed, which is an expansion chamber 28 in which straw and other waste reaching the rear end of the casing are swirled with the help of a rotor 12, as a result of which it is released and centrifugally removed through the hole 25. The lower part of the rear half of the casing 11 is formed by a grille 20. The concave 19 can be made of a large number of parallel ribs through which rows of wires and smaller diameter pass, and the grille 20 can be made Lc of the curved perforated metal poop l. Concave 19 may be provided with adjusting means by which its position relative to the axis of the rotor 12 is adjusted, as well as means allowing it to be removed from the combine for cleaning, repair or replacement. The grill 20 is preferably made removable in order to replace it. The front end of the central axial shaft 29 of the rotor 12 is supported by a transverse beam 30 (indicated by a dotted line in Fig. 3), made in the form of the forward-facing channel, which is an element of the housing 2. The rear end of the shaft 29 rotates in a bearing 30 fixed on the rear wall of section 27 casing from the outside of its side. The rotor 12 is driven by the engine 10 through a corresponding drive mechanism 31, including a variable-speed belt drive. The impeller 13 is made of several spiral blades 32 made of flat triangular-shaped metal sheets with straight edges attached with bolts 33 (Fig. 2 and 3) to the flanges 34 provided on the central hub 35 rigidly fixed on the front end of the shaft 29. The blades 32 are preferably mounted three, and besides the indicated edge, the blade has a straight radial edge 36 and an arcuate edge 37. As shown in FIG. 2 and 3, the central hub 35, on which the blades 32 are fastened, is also provided with a circular sealing disc 38 which goes into a recess (not shown). In order to maintain a gap of constant size between the blades 32 and the front part of the casing 11, the outer edges of the blades 32 are preferably parabolic in shape. A large number of spiral transport ribs similar to the ribs 26 are made on the inner wall of the front part of the casing 11. As shown in FIG. 2 and 3, the rotor has a hollow cylindrical structure, and for consideration here it can be considered as constituting one element of a complex rotor assembly, which contains an impeller 13 fixed to it and rotating with it. The rotor has a front part 39 in the form of a truncated cone and a rear part 40 in the form of a truncated cone. The angle of inclination of the front part 39 is about 45, and its front rim is provided with an annular flange 41 sealed to the central hub 35. The rear 40 part has a slightly smaller angle of inclination, and the rear rim of this part is mounted on the hub 42 rigidly fixed to shaft 29 near its rear end. Due to the presence of the conical part 39 combined with the impeller 13, the width of the loading part is not limited to the diameter of the cylindrical part of the casing 11. When the impeller 13 rotates, the breech 32 forms a truncated cone shaped as a truncated cone of the casing 11, as a result of which the gap between the outer edges of the impeller 13 and the inner surface of the housing 11 has a constant value throughout the edge. Several blades 43 (FIG., 1) in the form of a kerchief are fixed on the hub 42 and part 40 of the rotor in order to communicate the swirling to the residuals in the expansion chamber 28, thereby freeing them from the rotor 12 and allowing their own weight to fall through the outlet 25.- The Qilin wall 44 and straight corrugated whips 46 can reach the rear end of the rotor 12, thereby eliminating the need for the rotor part 40, the rear hub 42 and the vanes x 43. The straight corrugated whips 45 are located in three similar rows distance of 120 in an arc. Each row of straight grooved scourges 46 protrudes a short distance forward into the separation zone, thus overlapping the limited part of the concave 19 and the entire grille 20. Spiral grooved pests 46 are fixed on the front surface of the rotor 1, covering the surface of the rotor circumferentially around 120 °, and their longitudinal width is about four tenths of the total length of the cylindrical casing 11. However, within certain limits these values can vary, if necessary. Moreover, in a number of cases more or less can be used. The number of corrugated scourges located around the circumference is smaller, while the design is such that spiral corrugated scourges 46 perform the role of combined threshing and transporting corrugated scourges in the threshing zone of the combine, while the straight corrugated scourges 45 function in the separation zone. The device works as follows. The radially opposite spiral and straight grooved pests 46 and 45 and the spiral guide ribs interact with each other and feed the material axially back through the annular cavity formed between the rotor 12 and its casing 11. It should be noted that when the spiral corrugated scour 46 pass over concave 19, the mass not passing through the black, is sent back. If it is necessary to avoid an initially large length of solokel or other agricultural material, then by using the action of a concave 19 and spiral corrugated pests 46 any long material can be crushed; whereupon it is fed to the separation zone of the casing, where the threshing and grain separation are again performed using straight corrugated scourges 46 in combination with spiral guide ribs 26 that overlap with scourges 45. Although spiral corrugated bits 46 and straight corrugated scourges 45. are represented here, as continuous, however, the invention allows them to be made as separate sections, butted at the end and fixed with the formation of continuous corrugated scourge elements. It should be noted that the three spiral corrugated scourges 46, as well as a limited front section of each of the three linear scourges 45. Work in the threshing zone together with a concave, while the straight corrugated scourges 45 function in the separation zone in combination with the grille 20. Department the grain in these zones falls under the action of its own weight on the screw conveyor 18, which closes the threshing and separation zone, the passage under concave 19 and the sieve 20, and is unloaded with the help of a moving reciprocating Racks in kinnoe 21 m sieve. The conveyor 18 consists of a relatively long and relatively short screw sections, both sections having an oppositely directed pitch, as a result of which the mass exiting the threshing and separating zones is unloaded from the conveyor 18 in the middle part and enters the reciprocating rail. on m kinnoe 23. sieve.
    In the proposed straight-through combine harvester, clogging of the shroud of the threshing apparatus is excluded.
