[Detailed description of the invention] Industrial field of application The invention enables the cleaning opening provided in the bottom plate of the sorting section of a combine harvester to be opened wide without the lid body coming into contact with the surrounding machine frame etc. when opening and closing. The present invention relates to a cleaning port of a sorting section in a combine harvester that enables easy cleaning of the sorting section.

BACKGROUND ART Conventionally, a cleaning port opening provided on the bottom plate of the sorting part of a combine harvester has a cleaning port opening provided below the bottom plate of the sorting part, as described in, for example, Japanese Utility Model Application No. 57-133937 and Japanese Utility Model Application Publication No. 56-43352. Opening/closing lid that rotates or actual opening
A device that is opened and closed using a sliding lid is known, as disclosed in Japanese Patent No. 59-77857.

Problems to be Solved by the Present Invention However, with a device that opens and closes with an opening/closing lid that rotates downward, if the opening is made larger, when the large lid is rotated, the side of the machine underneath the sorting It cannot be opened and closed smoothly because it comes into contact with a frame, etc., and it is difficult to slide the complicatedly shaped bottom plate of the sorting unit over a wide range with a sliding lid. There is a problem in that it is not possible to provide a large cleaning opening in the bottom plate of the sorting unit so that the interior can be easily cleaned.

The present invention was devised to solve these problems in view of the above-mentioned actual situation, and although it is installed on the bottom plate of the sorting section of the combine, the opening/closing lid body is in contact with the lower machine frame, etc. It is an object of the present invention to provide a cleaning port for a sorting part in a combine harvester that can be opened wide without touching and can easily clean the sorting part.

Means for Solving the Problems In order to achieve the above object, the technical means taken by the present invention is to open a cleaning opening in the bottom plate of the sorting section of the combine, and to attach the tip of the opening to the front half of the cleaning opening. An opening/closing lid is provided which is pivotally attached to the front edge of the cleaning opening and rotates downward, and a sliding lid that slides back and forth is provided at the rear part of the cleaning opening to open and close the cleaning opening. The device is characterized in that it is provided with a locking device that locks the lever for opening and closing the opening/closing lid in the closed position of the opening/closing lid that closes the front half of the cleaning opening and the slide lid that closes the rear half of the cleaning opening. It is something.

Function of the invention To explain the function of the invention configured as described above, when opening the cleaning port provided on the bottom plate of the sorting section of the combine, first, the lever for opening/closing the opening/closing lid, which is pivotally attached to the front edge of the cleaning port, is opened. Rotate downward to open the front half of the cleaning port, and if you want to open the cleaning port even wider, loosen the slide lid fixing provided on the rear half of the cleaning port and slide the slide lid backwards. If you tighten the fixture in this state, the rear half of the cleaning port will also be opened, so even if the cleaning port has a wide opening as a whole, the rotating opening/closing lid and the sliding sliding lid will cooperate. The cleaning port can be opened smoothly so that inspection of the cleaning port and removal of clogs can be easily performed. When closing the cleaning port, first close the slide lid and then close the opening/closing lid, and the lever for opening/closing the opening/closing lid is locked with the locking device provided on the sliding lid, thereby locking the opening/closing lid in the closed state. It is something that can be done.

Embodiment The structure of the present invention will be described with reference to an embodiment shown in the drawings. 1 is a combine harvester body frame 2
The threshing machine is mounted on the top, and the lower part of the handling chamber 4 in which the handling barrel 3 is mounted is composed of a swinging sorting body 5, a sorting air passage 6, a first spiral 7, a second spiral 8, etc. Sorting section 9
The first helical bottom plate 10 and the second helical bottom plate 11 can be opened and closed to enable cleaning when these parts become clogged with waste straw or the like.

12 is a bottom plate of the sorting section 9, and the bottom plate 1
2 has a large cleaning opening 13 that can easily clean the sorting section 9 from the lower position of the most spiral bottom plate 10 to the rear of the machine. Hinge 14 on the front edge of
An opening/closing lid 15 that rotates downward is pivotally mounted via the opening/closing lid 15. In the rear half of the cleaning port 13, stoppers 16 provided on the left and right edges of the cleaning port 13,
Slide lid 17 that slides back and forth guided by 16
is provided.

Reference numeral 18 denotes a lever for opening and closing the opening/closing lid 15 which is movable up and down, the base end of which is pivotally attached to a rotation fulcrum 19 vertically disposed at the rear end of the opening/closing lid 15, and the lever 18 extends rearward. A grip portion 18a curved downward is provided on the end side.
is formed. Further, a pin 20 is provided in the middle of the lever 18 so as to protrude laterally in the shape of a hook.
Reference numeral 21 denotes a locking device consisting of a plate spring attached to the lower surface of the slide lid 17 via bolts 22, 22, and the locking device 21 slides the slide lid 17 forward and closes the rear half of the cleaning port 13. Then, when the front half of the cleaning port 13 is closed with the opening/closing lid 15, the pin 20 protruding from the lever 18 for opening/closing the opening/closing lid 15 is engaged with the locking portion 21a, and the opening/closing lid 15 is closed. It is now possible to lock. 23 is a long hole formed in the opening/closing lid, and 24 is a bolt that is inserted through the long hole 23 and fixes the slide lid 17 in an arbitrary position.

In the above configuration, in order to open the cleaning port 13, first grasp the grip part 18a of the lever 18 and rotate the opening/closing lid 15 downward.
Since the opening is large enough to close the front half of the cleaning opening 13, it can be opened smoothly without coming into contact with the fuselage frame 2 or the like. Then bolt 24
The rear half of the cleaning port 13 can be opened by loosening the slide lid 17 and swinging the slide lid 17 backwards, so the large cleaning port 13 can be opened even in the limited space of the bottom plate 12 of the sorting section. If the bolt 24 is tightened and fixed again, cleaning and inspection of the sorting section 9 can be easily performed. When closing the cleaning port 13, loosen the bolt 24, slide the slide lid 17 forward to close the rear half of the cleaning port 13, and then grasp the grip portion 18a of the lever 18 to close the opening/closing lid 15. When the pin 20 is rotated to the original position, the pin 20 is engaged with the locking portion 21a of the lock device 21 made of a plate spring of the slide lid 17, so that the opening/closing lid can be reliably closed. Moreover, the pin 20 cannot be locked unless the slide lid 17 is in the completely closed position, so when the slide lid 17 is open, the opening/closing lid 15 rotates downward and easily slides toward the aircraft. You can check from
It is possible to reliably prevent forgetting to close the slide lid 17.
