Description

[Detailed description of the device]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cleaning device for a thresher that cleans and removes grains remaining in each gutter of the first screw conveyor and the second screw conveyor.

[0002]

[Prior art]

 Conventionally, as shown in Japanese Utility Model Publication No. 63-32612, a cleaning port opened and closed by a bottom cover is opened on the bottom of each gutter of the first screw conveyor and the second screw conveyor, and each bottom cover is connected via a link mechanism. There was a technology for opening and closing in conjunction.

[0003]

[Problems to be solved by the device]

 In the prior art, since the link mechanism is provided between the No. 1 gutter and the No. 2 gutter, it is necessary to forcibly configure the link mechanism according to the space between the gutters, and the bottom cover is opened. Insufficient closing angle and inadequate opening / closing operation, and because the link mechanism was installed at the bottom of each trough, there is a problem that even in mud work near the running crawler, even if mud adheres to the bottom lid, the bottom cover may not open and close properly. It was

[0004]

[Means for Solving the Problems]

 Therefore, the present invention has a cleaning port opened on the bottom of each gutter of the first screw conveyor and the second screw conveyor, a bottom cover for opening and closing the cleaning port, and a link mechanism for opening and closing the bottom cover in an interlocking manner. In the threshing machine cleaning device provided, the link mechanism is provided on the outer surface of the side plate on one side of the threshing section, and the problems of the conventional techniques can be solved.

Further, the link mechanism is provided with an operation lever for projecting a tip portion below a lower edge of a cover that covers the outside of the side plate when the bottom lid is opened, and the lever is made to interfere with an inward lower edge rib of the cover. By making it impossible to attach the cover when the bottom lid is opened, it is possible to prevent the work from being started in the open state of each bottom lid.

Further, when the bottom cover is closed, the cover is locked to the side plate above the lower edge of the cover that covers the outside of the side plate, and when the bottom cover is closed, the operating lever of the cover is provided in the link mechanism. The inward lower rib on the bottom prevents the lever from moving from the closing operation position to the opening operation position, so the cover is attached during work, so the operation lever is held in the closed operation position during work. If the lever is not properly held and locked in the closing operation position, or if it may come off due to a failure of the holding part, the lever will only move a little in the opening direction and will not be opened. , It is possible to prevent the bottom lid from being completely opened during the work and releasing the grain into the field.

Further, by supporting each opening / closing fulcrum shaft of the bottom lid laterally between the left and right side plates of the threshing part, the fulcrum shaft can support both ends to increase the rigidity of each fulcrum part of the link mechanism. Is.

Further, since each opening / closing fulcrum shaft of the bottom lid is provided between the most-screw conveyor and the No. 2 screw conveyor, the fulcrum shafts are close to each other so that each link length of the link mechanism is shortened. Therefore, the link mechanism can be made compact.

[Effect of the invention]

 As is apparent from the above-described embodiments, the present invention has the cleaning ports (40) (41) provided on the bottoms of the gutters (38) (39) of the first screw conveyor (32) and the second screw conveyor (33). ), A bottom cover (42) (43) for opening and closing the cleaning ports (40) (41), and a link mechanism (44) for opening and closing the bottom cover (42) (43) in an interlocking manner. In the cleaning device of the threshing machine, the link mechanism (44) is provided on the outer surface side of the side plate (48) on one side of the threshing section (4), and the problems of the conventional technology can be solved.

In addition, when the bottom lids (42) (43) are opened, an operating lever (45) for projecting a tip portion below a lower edge of a cover (57) that covers the outside of the side plate (48) is connected to the link mechanism ( 44), and the lever (45) interferes with the inward lower edge rib (73) of the cover (57) to prevent the cover (57) from being attached when the bottom lids (42) (43) are opened. By making it possible, it is possible to prevent the work from being started in the open state of each bottom lid (42) (43).

Further, when the bottom lids (42) (43) are closed, the bottom lids (42) are locked to the side plates (48) above the lower edge of the cover (57) that covers the outside of the side plates (48). ) (43) When the cover (57) is closed, the operating lever (45) is provided on the link mechanism (44), and the inward lower rib (73) of the cover (57) is used to close the lever (45). Since the cover (57) is attached at the time of work by preventing the movement from the open position to the open operation position, the locking and holding of the operation lever (45) at the close operation position at the time of the work can be kept at the close operation position. Even if the lever (45) is not properly held and locked, or even if the lever (45) is disengaged due to a failure of the holding part, the lever (45) will move slightly in the opening direction and will not be opened. , The bottom lids (42) (43) are completely opened during work It is possible to prevent the grains from being released to the field.

Further, the opening / closing fulcrum shafts (46) (47) of the bottom lids (42) (43) are laterally supported between the left and right side plates (48) (49) of the threshing unit (4) to support them. The shafts (46) and (47) support both ends to increase the rigidity of each fulcrum of the link mechanism (44).

Further, since the opening / closing fulcrum shafts (46) (47) of the bottom lids (42) (43) are provided between the first screw conveyor (32) and the second screw conveyor (34), Since the fulcrum shafts (46) and (47) are close to each other, the link length of the link mechanism (44) can be shortened, and the link mechanism (44) can be made compact.
