DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing chamber provided with a front end through a dust passage at a rear end of a processing chamber in which a processing drum is provided. The present invention relates to a combine threshing device provided with the above.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Application No. 4-29897, an upper edge of a crimping net of a processing chamber is supported on an upper edge of a processing drum cover by a hinge structure, and a lower edge of the crimping net is used as a machine. Tighten from the outside to the lower edge of the processing cylinder cover via a bolt with a knob, fix the crimp net to the outer peripheral side of the processing cylinder opposite to the processing cylinder cover, remove the knob bolt, and attach a hinge piece on the crimp net side. There is a technique in which a connecting pin of a hinge piece on a processing drum cover side is pulled out to the rear of the machine, and a crimp net is taken out of the machine from a window formed in a side wall below the processing drum.

[0003]

In the prior art, when the crimping net is mounted, the hinge piece on the crimping net side and the hinge piece on the processing cylinder cover side are aligned, and a connecting pin is attached to the curled portion of the hinge piece. And the hinges had to be assembled, and it was very difficult to attach the crimp net.

[0004]

According to the present invention, a net frame is provided separately from the crimp net on the outer peripheral side of the crimp net in the processing chamber, the net frame being stretched in the circumferential direction of the processing cylinder. While supporting the upper edge of the processing drum cover via a fulcrum axis parallel to the processing drum axis, and tightening the lower end of the mesh frame to the lower edge of the processing drum cover from outside the machine via a bolt with a knob,
A crimping net is fixed to the outer peripheral side of the processing drum opposite to the processing drum cover via a net frame, the bolt with the knob is removed, and the net frame is rotated around the fulcrum shaft in a direction to separate the net frame from the processing drum. The crimping net is configured to be taken out of the machine in the circumferential direction of the processing cylinder from the lower end side of the net frame, so that the crimping net can be easily attached / detached simply by removing and attaching the bolts with knobs. Since there is no need to provide a net frame, the structure of the crimp net is simplified and the weight is reduced, so that the work of attaching and detaching the crimp net can be performed more easily.

In addition, the mesh frame is divided into upper and lower portions, and the upper mesh frame and the lower mesh frame are connected via a fulcrum shaft. By rotating the mesh frame, the amount of rotation operation of the entire net frame is reduced, the gap required for attaching and detaching the crimp net can be obtained larger, and the attachment and detachment of the crimp net can be performed more easily. is there.

There is disclosed a dust suction / discharge fan (38a) which is opened above the straw rack (32) toward the handling drum (6).

Since the suction / discharge fan (38a) has the suction port (19a) opened in the direction in which the Karin (34) is blown out, it has excellent suction efficiency and is generated inside the threshing unit (4). Most of the dust and the like can be sucked, and it is possible to prevent the dust from rising out of the machine from each part of the threshing unit (4). Also, the body wall of the suction and discharge fan (38a) faces the discharge port (53),
Since the suction ports (19a) do not face each other, there is no direct inhalation of unagglomerated particles discharged from the dust discharge port (53) while being mixed with the straw.
Grain loss can be reduced. Further, since the processing drum shaft (7a) and the suction and discharge fan shaft are parallel to each other and the rear end of each shaft protrudes to the rear surface of the threshing unit (4), the suction and discharge fan ( 38a), power can be transmitted by simple belt transmission.

As is apparent from the above embodiment, the present invention provides a process for connecting the front end side to the rear end side of the handling chamber (23) in which the handling cylinder (6) is provided through the dust passage (51). Room (49)
In a combine threshing apparatus in which a processing drum (7) is provided inside the processing chamber (49) in parallel with the handling drum (6), the processing is performed on the outer peripheral side of the crimping net (52) of the processing chamber (49). Mesh frames (54) (55) that are stretched in the circumferential direction of the trunk (7)
Is provided separately from the crimping net (52), and the upper ends of the mesh frames (54) and (55) are connected to the upper edge of the processing drum cover (48) via a fulcrum shaft (58) parallel to the processing drum shaft (7a). And the lower ends of the net frames (54) and (55) are fastened to the lower edge of the processing cylinder cover (48) from outside the machine via bolts (59) with knobs. A crimping net (52) is fixed to the outer peripheral side of the body (7) via the net frames (54) and (55), and the bolts (59) with the knobs are removed, and the net frame (58) is centered on the fulcrum shaft (58). The crimping net (52) is rotated from the lower end side of the net frame (54) (55) to the outside in the circumferential direction of the processing cylinder (7). It is configured to remove the bolt with knob (59). Mounting only with a crimp network (52)
Can be easily attached and detached, and it is not necessary to provide the net frames (54) and (55) on the crimp net (52), and the structure of the crimp net (52) is simplified and the weight is reduced. This has a remarkable effect that the attaching / detaching operation of the net (52) can be performed more easily.

The screen frames (54) and (55) are vertically divided, and the upper screen frame (65) and the lower screen frame (66) are connected via a fulcrum shaft (67). Since the lower mesh frame (66) is configured to be further rotated from the rotating position of the upper mesh frame (65), the amount of rotation operation of the entire mesh frames (54) and (55) can be reduced.
