Description

[Detailed Description of the Invention] [Industrial field of application] According to the present invention, the upper case is opened and closed about the axis opposite to the handle and about parallel to the handle axis. The present invention relates to a threshing device which is rotatably supported by a lower case and in which an upper chain type waste straw holding and conveying device is disposed on the lower side of the handling room in the grain culm conveying direction.

[Conventional technology]

In the above threshing device, in the past, for example, the actual Kaisho Sho 63-
As disclosed in Japanese Patent No. 155333, the handling case is supported by an upper case that covers the handling chamber, and a holding rail that faces the feed chain is attached to the swinging end side of the upper case.
There has been a structure in which the discharge straw holding and conveying device is mounted on the lower case side in a fixed position.

[Problems to be solved by the device]

The above conventional structure is configured to facilitate maintenance work such as cleaning for removing tangled straw scraps in the feed chain or the handling chamber after the threshing work is completed.

However, since the upper case swings open only in the upper part of the handling chamber, it is difficult to inspect the work around the discharged straw transporting unit, and further, when the scrap dust is entangled in the discharged straw holding and conveying device, Removal work was difficult and there was room for improvement.

The present invention aims to eliminate the above disadvantages.

[Means for solving the problem]

The feature of the present invention is that in the threshing device described at the beginning,
The handling case is supported by the upper case, and a gripping rail facing the feed chain is provided on the swinging end side of the upper case. From the above, it is configured to cover continuously from the discharge straw conveying section, and the rear extension portion of the upper case supports the conveying chain of the discharge straw holding and conveying apparatus so that the upper case and the handling cylinder can be lifted and opened. is there.

[Action]

According to the above configuration, [a] When the upper cover is rocked and opened upward, a portion extending from the handling chamber to the discharge straw conveying section appears, the holding rail and the handling cylinder are lifted together with the upper cover, and the discharge straw conveying chain also faces it. Lift up from the gripping rail.

[B] As a result, it is easy to inspect parts from the handling room to the waste straw conveyor, remove the straw scraps entangled in the handling cylinder and feed chain, and remove the jammed scraps in the exhaust straw conveyor. It can be carried out.

[Effect of device]

Therefore, the work efficiency of the maintenance work can be improved by the above actions [a] and [b].

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

2 and 3 show a combine threshing device (1). This threshing device (1) holds a tip of a grain by a drive barrel (5) that is driven and rotated in a handling room (4) while holding the stocker side of a grain culm by a feed chain (2) and a holding rail (3). Is treated, and the treated material leaking through the receiving net (6) stretched along the outer peripheral portion of the handling cylinder (5) is treated with a grain, a second product and It is configured to sort out waste scraps and the like.

Then, the grain is configured to be carried out by the first item collecting screw (8) to the grain collecting device (31) on the lateral outside, and the second item is returned to the handling chamber (4) for reprocessing. Configured,
Fine dust scraps are discharged outside the machine by a dust blower (9). In addition, the waste straw after the handling processing is carried and held by the upper chain type waste straw that is disposed in the waste straw transport section (30) from the end of the feed chain (2) to the lower side of the handling chamber (4) in the grain transfer direction. The device (10) is configured to convey and supply the wastewater to the upper part of the waste wall cutter (11).

The rotary power for the handling barrel (5) is configured to be supplied from an unillustrated driving part to an input pulley (13) provided on the upper side of the handling barrel shaft (12) in the grain culm transport direction. For (10), from the transmission pulley (14) provided on the lower side of the handling barrel shaft (12) in the grain culm transport direction to the transmission belt (15).
And the transfer device (1) via the bevel gear transmission mechanism (16).
The power is supplied to the drive sprocket (17) on the conveyance start end side of (0).

Then, as shown in FIG. 1, the upper case (18) of the threshing device (1) supporting the handling barrel (5) is located at a position opposite to the handling port (19) and It is pivotally supported on the lower case (20) so as to open and close and swing around an axis (P) substantially parallel to the axis. A holding rail (3) facing the feed chain (2) is attached to the swinging end side of the upper case (18), and the upper case (18) is held and conveyed by an ejecting straw carrier (10).
Extends to the upper side and discharges waste straws from the handling room (4) (30)
Continuously, and at the rearward extension of the upper case (18), the transport chain (2
It is configured so that it can be lifted and opened by holding it together with the upper case (18).

More specifically, the upper case (18) covers the entire upper surface of the threshing device (1), and a part of the upper part of the cutter case (22) is cut out so that the upper case (18) partially overlaps with the waste straw cutter (11). The entire discharge straw conveyor chain (21) is configured to cover the entire upper area, and the entire area is integrally swung upward. Then, the support frame (23) supporting the discharge straw holding and conveying device (10) is swingable integrally with the upper case (18) around the axis (P) so that the lower case (20) side support frame (24). ) Is pivotally connected to the upper end of the exhaust pipe, and is extended laterally so as to bypass the upper part of the exhaust straw transfer path, and is connected to a middle part of the bevel gear case (25) and the exhaust straw transfer chain (21). Also, the pillar frame (23) located above the discharge straw transport path is received and supported at a predetermined position,
In addition, the receiving frame (26) for locking is extended from the discharge wall cutter (11) in a state of bypassing the discharge straw transport path. Then, at the time of threshing work, the lock member (27) that can be released is positioned and fixed.

With this configuration, when the upper case (18) is opened and rocked during maintenance work such as cleaning after the completion of the threshing work, both the feed chain (2) and the discharged straw conveying chain (21) are opened. As a result, it is possible to easily remove straw debris.

In addition, since the handling cylinder (5) and the exhaust straw-carrying chain (21) swing integrally, the power transmission belt (15) can be opened and closed while maintaining the transmission state. There is no need to provide a dedicated member.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
