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 unit of a threshing device provided with chaff sheaves.

[0002]

2. Description of the Related Art Conventionally, when a wet grain culm harvested in the early morning or after rain is targeted, it is necessary to prevent clogging of the gap of the chaff plate due to adhesion of the treated matter to the chaff plate.
It has been proposed that the chaff plate be swingably mounted and vibrated by a drive device.

[0003]

However, in the case where the object to be treated is severely wet, it is difficult to reliably prevent the object to be attached to the chaff plate due to vibration, and it is extremely difficult to drop the object once attached. Therefore, there was room for further improvement in terms of improving the sorting performance. An object of the present invention is to make it possible to reliably prevent clogging of a treated product with a chaff sieve even when the treated product is severely wet.

[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. In a threshing device provided with chaff sheaves arranged in parallel in a direction, a cleaning tool for the chaff plate is provided movably in either the juxtaposition direction or the longitudinal direction of the chaf plate, and a drive device for moving the cleaning tool is provided. ..

[0005]

In other words, since the cleaning object moved by the drive unit can scrape off the object to be processed adhering to the chaff plate, the object to be processed can be surely removed from the chaf plate even if the object is extremely wet, and the chaf sheave It is possible to reliably prevent clogging and improve the grain collection efficiency sufficiently and reliably.

[0006]

As a result, it becomes possible to provide a threshing device which is capable of reliably preventing clogging of a processed product in a chaff sheave and is further excellent in sorting performance.

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. The sorting unit 10 is provided with a rocking sorting case 16, a wind picker 17 for picking up wind, a screw conveyor 19 for collecting the first product, a screw conveyor 20 for collecting the second product, and a dust blower 22.
Swing sorting case 1 for processing objects dropped and supplied from the handling chamber 13
6, the swing selection processing is performed while being conveyed in the axial direction of the handling cylinder 14, and the processed material dropped and supplied from the swing selection case 16 is subjected to the wind selection while being conveyed in the axial direction of the handling cylinder 14 by the action of the Karako 17. Along with processing, the threshed grains are configured to be sent to the grain tank 11 by the screw conveyor 19 for recovery of the first product and the screw-type lifting conveyor, and the second product that is insufficiently sorted is used as the screw conveyor 20 for the second product recovery. It is configured to be returned to the swing selection case 16 by a screw type return conveyor 24. Glen pan 2 in rocking sorting case 16
6, a chaff sheave 27 connected to the rear side, a Glen pan 28 and a Glen sheave 29 located below the chaff sheave 27, and a Straw rack 32 for receiving a processed material from the dust inlet 30 of the handling chamber 13,
A straw rack 33 is provided on the rear side of the chaff sheave 27.

As shown in FIG.
A large number of chaff plates 3 inclined in the swing direction
4, the chaff plate 34 is attached so that the inclination angle can be freely changed, and the link member 35 interlocked with all of the chaf plate 34 is wire interlocked with the electric motor 18 for adjusting the chaf plate angle. The chaff plate 34 is appropriately set in angle according to the property of the object so that the sorting can be performed well. 3 and 4
As shown in FIG. 2, the brush-like cleaning tool 21 for the chaff plate 34 is attached to the chaff plate 34 along the guide 25.
The cleaning tool 2 is movably and rotatably provided in
1 is provided with an electric drive device (electric motor) 37 for engaging the pinion 31 that rotates integrally with the rack 36 with the rack 36 and rotating the cleaning tool 21 and the pinion 31. The chaff sheave 27 is configured to be able to scrape off the treated matter, so that even if the treated matter is extremely wet, the chaff plate 34 can be surely removed from the treated matter so that the chaff sheave 27 can be prevented from being clogged. is there. The cleaning tool 21 is configured to be stopped at the retracted position below the Glen pan 26 when not operating. It should be noted that the drive device 37 is configured to penetrate a slide guide shaft 36a provided in parallel with the rack 36 so that the drive device 37 itself can move along the slide guide shaft 36a without rotating when the cleaning tool is driven. I am doing it. As shown in FIG. 5, the mode indicator 38 for switching the mode of the angle control of the chaff plate 34 between the automatic mode and the wetting mode is provided, the sensor 39 for detecting the amount of processed material on the chaff sheave 27 is provided, and the grain culm of the reaping unit 2 is provided.

In the automatic mode, the chaff sheave 27 is provided. The angle of the chaff plate 34 is automatically adjusted so that the standing angle of the chaff plate 34 becomes larger as the amount of the processed material increases, and the chaff plate 34 is fixed at the maximum standing angle in the wet mode. Second control means 42 for automatically operating the cleaning tool moving drive device 37 based on the information from the mode indicator 38 and the grain culm detection sensor 40 is provided. In the automatic mode, the cleaning tool 21 is stopped below the Glen pan 26. In the wet mode, the cleaning tool 21 is rotated and moved after the set time has elapsed from the time when the harvested culms have disappeared, and the reciprocating movement has been performed for the set number of times or the set time, or with the sensor 40. The cleaning tool 21 is configured to stop below the Glen pan 26 when a grain culm is detected.

[Other Embodiments] The moving direction of the cleaning tool 21 may be the longitudinal direction of the cheaf plate 34, as shown in FIGS. 6 and 7. In this case, the side plate 43 of the swing selection case 16
It is desirable to bend and form a retracting space for the cleaning tool 21. The specific configurations of the cleaning tool 21 and its drive unit 37 can be appropriately changed. For example, as shown in FIGS. 8 and 9, the cleaning tool 21 is formed of a comb-shaped plate or the cleaning tool 21.
The top 44 attached to the screw shaft 4 rotated by the drive device 37
The cleaning tool 21 may be configured to be screwed into the movable member 5 and moved with the rotation of the screw shaft 45.
