The conveying body 86 is horizontally disposed in the lower portion of the second processing drum 41 so as to be overlapped with the second processing drum 41 in a plane parallel to the second processing drum 41, The grains or the like falling through the crimp net 41a from the second processing drum 41 of the second feeding drum 41 by the first feeding drum 86 and the second feeding drum 42 by the feeding drum 86, And is conveyed in a direction opposite to the conveying direction to be discharged onto the swing plate 32. [

The rear surface of the swing discriminating plate 32 is connected to be swingable by a swing drive mechanism 50 such as a crankshaft.

The feed fan 38 is a free fan that sends a selective air to the upper and lower portions of the feed plates 33 and 34 and a wind which flows between the chaff sheave 35 and the grain sheave 36 and below the grain sheave 36 By blowing air from the tuyeres 22, which are the main blowing devices to be fed, the grain which leaks down the crimped nets 31 and 41a is diffused. The grains of the grains and the grains are sorted by the gravity selection and the wind selection to select the grains 1, 2, and straw.

The upper surface of the feed plate 33 and the rear feed plate 34 is formed into a wavy shape so that the grain can be easily conveyed backward.

The No. 1 conveyor 23 horizontally disposed below the grain sheave 36 is configured to communicate with the grain conveyor 24 to take the grain into the grain tank 12.

A second conveyor 25 is horizontally disposed on the rear side of the first conveyor 23 and the second conveyor 25 returns the second conveyed material to the second conveyor 26. The second conveyor 26 is conveyed to the second processing unit 27 connected to the front end of the second conveying conveyor 26. The second conveying unit 27 After the branches and stems are removed by the No. 2 treatment drum, they are fed back to the sorting start section of the swing sorting plate 32.

In this configuration, the grain stem held by the feed chain (7) is deflected by the rotation of the handling drum (6) provided in the handling chamber (20) of the threshing section (5) The discharged straw or the like is sent to the rear-side straw discharge cutter 52, and is discharged to the field from behind after cutting.

On the other hand, grains, straws, and the like leaking through the crimp net 31 fall on the swing sorting plate 32, and are sent backward while swinging. The grain, straw or the like is passed through the chaff sheave 35, the grain sheave 36, and the like and is guided to the grain flow plate and falls on the first cylinder. During the fall of the grain, the grain blowing fan 38 and the tuyeres 22 The wind selection is carried out by the selected wind.

A sucking fan 60 is arranged above the rear end of the swinging plate 32. Sucking straws delivered from the straw rack 40 are sucked by the suction fan 60, To the back of the gas.

A configuration in the vicinity of the delivery port 51 will be described with reference to FIG.

The grains and straws selected from the drum 2 (41) of Song Jung-gu are discharged from the discharge port (51). Further, the right side wall is notched when viewed from the back side of the base of the suction fan exhaust port 61, and the exhaust guide guide exhaust port 61a is provided. In addition, a plurality of wind deflector plates (87) are arranged inside the suction fan exhaust port (61). In the present embodiment, the wind deflector plates 87 are provided so as to be substantially parallel to each other at substantially equal intervals, and are inclined from the right side to the left rear side when viewed in a plan view have. In addition, a plurality of the wind deflector plates 87 are interlocked with each other so that the wind direction can be adjusted.

However, the number of the wind deflector plates 87 is not limited to the present embodiment, and it is also possible to arrange the wind deflector 87 so that the angle of inclination in the left and right direction is gradually reduced or increased. The distance between the wind deflector plate 87 and the wind deflector plate 87 is substantially the same as the distance between the wind deflector plate 87 and the wind deflector plate 87. However, .

With such a configuration, the straw discharged from the discharge port 51 is easily guided from the suction fan exhaust port 61 to a position where it is exhausted, thereby improving the diffusibility.

At the rear of the suction fan exhaust port 61, there is disposed a cutter device 81 of a discharge straw for cutting straws sent backward by a feed chain 7 and a straw discharge chain (not shown). The cutter device 81 of the discharge straw has a low-speed shaft 52a having a plurality of low-speed rotary blades and a high-speed shaft 52b having a plurality of high-speed rotary blades, And a diffusion conveyor 82 for spreading the cut straws are likewise supported in the lateral direction of the body.

In the conventional arrangement, when the straw discharged by the cutter device 81 of the discharge straw is cut, since the discharge side of the discharge straw is located on the left side as viewed from the back side of the base, the volume of the cut straw is larger than the right edge . The discharge straws on the aeration side are also sent to the right by the diffusion conveyor 82 and spread to some extent, but the deflection can not be solved.

Therefore, as shown in Fig. 11, the cutter device 81 of the discharge straw has a notch 83a at the lower left when viewed from the rear side of the base of the front cover 83. As shown in Fig. 11 shows a state in which the cutter device 81 of the discharge straw is pivoted rearward about the support shaft on the right side and is provided at a lower portion of the front cover 83 covering the front of the diffusion conveyor 82, And a notch portion 83a whose left side gradually opens wide when viewed from the rear side is formed.

This configuration makes it possible to prevent the exhaust air from the suction fan 60 disposed at the front side from blowing backward from the suction fan exhaust port 61 to flow into the cutter device 81 of the discharge straw from the notch 83a, When the straw is diffused by the diffusion conveyor 82, the exhaust becomes exhausted and the diffusion property is improved.

A diffuser plate 72 is provided below the suction fan exhaust port 61 and the exhaust port 51 to improve the diffusing property of the exhaust. As shown in Figs. 7 and 8, the diffuser plate 72 is disposed in a substantially horizontal direction from a rear end to a rear end of the oscillation discriminating plate 32 and having a width corresponding to the lateral width of the oscillating discriminating plate And the swinging discriminating plate 32 so as to swing together with the swinging motion of the swinging discriminating plate 32. In this way, the straw is sent backward from the straw rack 40 and the straw discharged from the delivery port 51 is swung and flowed down.

A guide guide 84 is provided on the rear right side of the fan cover 85 for covering the upper portion of the suction fan 60 as viewed from the rear side of the exhaust port 51. The spread guide guide 84 has a generally trapezoidal plate arranged obliquely rearward and rearward from the front portion of the delivery opening 51 to be fixed to the fan cover 85. The length in the forward and backward direction is the same as the length of the delivery opening 51, And the length in the vertical direction is arranged so that the upper end thereof is substantially aligned with the upper end of the power outlet 51 and the lower end thereof is located below the power outlet 51 . The lower portion of the evacuation guide guide 84 is substantially triangularly shaped so that the side of the evacuation port 51 becomes larger, and serves as the evacuation guide guide vent 61a.

With this configuration, the discharged discharge in the left direction in the discharge opening 51 is guided obliquely rearward in the discharge guide guide 84, and is diffused and discharged to the left than in the prior art. In addition, the exhaust gas discharged obliquely downward and downward from the exhaust port 51 is blown back and forth by the exhaust air of the suction fan 60 sent from the exhaust guide guide exhaust port 61a and diffused. In this way, the exhaust discharged from the delivery port 51 is prevented from being discharged into the field as a lump.

Further, since the diffusion plate 72 is disposed below the suction fan exhaust port 61, it is possible to allow the exhaust air from the suction fan 60 to contact the diffusion plate 72. As a result, the wind from the suction fan exhaust port 61 always strikes strongly, so that the straws delivered from the straw rack 40 and the straw discharged from the delivery port 51 are forcibly blown out. Therefore, the straw is diffused without aggregation, which is very good to look at.

9 and 10, it is also possible to attach a plurality of guides 80 made of sheet-like members to the upper surface of the diffusion plate 72. [ That is, the guide 80 is a substantially rectangular plate-like member, and each of the guides 80 is installed on the diffusion plate 72 in parallel. Further, the guide (80) has a structure in which a plurality of guides are interlocked, and the angle is adjustable in accordance with the amount of the evacuation. However, the guide 80 may be configured so that the inclination angles in the left and right direction are gradually reduced or increased. The distance between the guide 80 and the guide 80 is substantially equally spaced. However, the distance between the guide 80 and the guide 80 can be made shorter by the right or left side in accordance with the amount of evacuation. It is also possible to configure the height of the guide 80 so that the left side is high and the right side is low or the left side is low and the right side is high in accordance with the amount of exhausting.

In the present embodiment, the guides 80 are arranged obliquely from the left to the right rearward when viewed in plan.

In this way, even when the straw delivered from the straw rack 40 or the straw delivered from the delivery port 51 is biased to the left when viewed from the back side of the base, the guide is guided and uniformly diffused Lt; / RTI > Further, the airflow from the suction fan 60 can be changed by the guide 80 to promote diffusion. Further, the direction of the guide 80 is not limited to the case described in this embodiment, and the number of the guides 80 can be changed.

TECHNICAL FIELD The present invention relates to a technology of a straw discharge processing part for discharging a threshing part of a combine, in particular a straw discharged from a threshing part, into a field, and can be widely applied to agriculture.
