CONSTITUTION:Chaff plates 34 are attached to a chaff sieve 27 in such a way that the angle of inclination is freely changeable and an interlocking member 35 linked to all the chaff plates is interlocked to a release wire 36 and a return spring 37. An oscillation sorting case is equipped with an actuator 38 to supply impact strength to the interlocking member in the direction opposing the return spring 37.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a swinging and sorting case for transporting and sorting a processed material which is dropped and supplied from a handling chamber, and a plurality of chaff plates inclined in the swinging direction are arranged side by side in the processed material transporting direction. The present invention relates to a sorting section of a threshing device in which a chaff sheave is provided, a chaf plate is attached so that its inclination angle can be freely changed, and a linking member that is interlocked with all of the chaf plates is interlocked with a pull operation tool for adjusting the chaf plate angle and a return spring.

[0002]

2. Description of the Related Art Conventionally, in a chaff sheave in which the angle of a chaff plate can be arbitrarily set and fixed according to the property of a processed object, as shown in Japanese Patent Application Laid-Open No. 4-63511, selection is performed only by the rocking. It was configured such that the processed grains were dropped from the gap between the chaff plates.

[0003]

However, when the treated product is so wet that the grain culms harvested after early morning or after rain are targeted, the chaff plate is clogged due to adhesion of the treated product to the chaff plate, Grains were prevented from falling and the efficiency of grain recovery was likely to drop, and there was room for further improvement in terms of improving sorting performance. An object of the present invention is to effectively prevent clogging of a processed product in a chaff sheave, and to devise a structure for that purpose so that the structure can be easily modified by effectively utilizing the original structure.

[0004]

A feature of the present invention is that a swinging and sorting case for transporting and sorting a workpiece to be dropped and supplied from a handling chamber is provided with a large number of chaff plates inclined in the swinging direction. The chaff sheaves arranged side by side are installed, the chaff plate is attached so that the inclination angle can be freely changed, and the interlocking member that interlocks with all of the chaff plates is returned in the threshing device that interlocks with the tension operation tool for adjusting the chaff plate and the return spring. An actuator is provided to apply an impact force to the interlocking member against the spring.

[0005]

[Effect] In other words, since the actuator can apply an effective impact force to the chaff plate to drop the adhered matter, it is possible to reliably prevent the chaff sheave from being clogged even with a severely wet treated material, and to sufficiently improve the grain recovery efficiency. And it can definitely improve. Moreover, the structure for fixing and setting the angle of the chaff plate arbitrarily, that is, since the pulling operation tool and the return spring are combined to allow the swing of the chaff sheave, the impact force in the direction against the return spring is large. By effectively utilizing the characteristic that can be easily added, a simple modification by simply adding an actuator that acts on the interlocking member is sufficient, and the modification cost can be sufficiently reduced.

[0006]

As a result, it becomes possible to provide a threshing device which is capable of effectively preventing clogging of a treated product in a chaff sheave and which can be easily modified, and which is further excellent in terms of sorting performance and modification cost.

The boarding operation unit 12 is arranged in front of the vehicle to construct a self-removing combine.

The threshing device 7 is constructed as shown in FIG. That is, the handling barrel 14 is provided in the handling chamber 13 so as to be rotatable about the lateral axis in the longitudinal direction of the machine body, and the receiving net 15 provided in the lower portion of the handling chamber 13 is made of a perforated plate-like resin. It is configured so that there is no attachment of clams or wet treated material to the. Swing sorting case 16, wind picker 17 for wind selection in sorter 10, auxiliary picker 18 for blowing drying air to swing picking case 16 when threshing control is in wet mode, screw conveyor 19 for collecting No. 1 product, 2 A screw conveyor 20 for collecting food, a diffusion cylinder 21 for collecting clams from straw discharged from the handling chamber 13, and a dust blower 22 are provided, and a processed product dropped and supplied from the handling chamber 13 is handled by the rocking sorting case 16. Torso 14
Is transported in the direction of the axis of the oscillating sorting process, and the processed material dropped and supplied from the oscillating sorting case 16 is subjected to the wind selection process while being transported in the axial direction of the handling cylinder 14 due to the action of the Karako 17 and threshing. The grain tank 11 is collected by the screw conveyor 19 for collecting the first product and the screw-type lifting conveyor 23.
The second product, which has not been sufficiently sorted, is returned to the rocking sorting case 16 by the second product recovery screw conveyor 20 and the screw type reduction conveyor 24. A straw cutting blade 25 is provided on the diffusion drum 21 to cut and remove the straw co-rotating with the diffusion drum 21. The Glen pan 26, the chaff sheave 27 connected to the rear side of the swing selection case 16, and the Glen pan 28 located below the chaff sheave 27.
Further, a gren sheave 29, a straw rack 32 with a gren pan 31 for receiving a processed material from the dust inlet 30 of the handling chamber 13, and a straw rack 33 connected to the rear side of the chaff sheave 27 are provided. As shown in FIG. 3, the chaff sheave 27 is provided with a large number of chaff plates 34 inclined in the swinging direction.
