Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing sorting device that is provided with a sorting section below a handling chamber to which sorting air is supplied in the direction of the rotation axis of the handling barrel.

In the above-mentioned threshing sorting device, when inspecting or cleaning the receiving net, the handling barrel can be removed from the working position so that a wide space can be secured above the receiving net for easy work. , it is configured to be pulled upward from the working position, requiring time and effort to remove, reducing work efficiency for inspection, repair and cleaning, and reducing the strength of the aircraft due to the ability to remove the handling trunk. A major modification was required to strengthen the structure against the drop in performance, which had the disadvantage of increasing costs.

The present invention makes it possible to easily and quickly remove the handling cylinder from the working position, and also to make it possible by a simple modification that makes effective use of the original structure, thereby allowing inspection and repair of the receiving net. The purpose of the present invention is to make it possible to construct a device that can be efficiently cleaned and cleaned at a low cost.

Next, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 1, a handling chamber 1 is formed in the upper part of the machine, and a handling barrel 2 is installed inside this handling chamber 1 so that it can be freely driven, and the harvested grain culm is transferred to the handling chamber 1 by a feed chain 3. It constitutes a threshing section in which the threshed waste straw is carried out to the outside of the handling room by the feed chain 3, and the threshed waste straw from the feed chain 3 is brought to one side of the machine body. The endless rotation chain 4 for the stock side and the endless rotation chain 5 for the tip side to be carried out of the machine are placed in the handling room 1.
It is located at the rear of the Then, a sorting section having a sorting plate 6 which can be driven and moved freely for the processing materials falling and supplied from the handling chamber 1, and a winch 7 that supplies sorting air in the direction of the rotation axis of the handling cylinder 2 is installed in the handling chamber 1. At the same time, it is arranged so that dust and sorting air from the sorting section are discharged to the outside of the machine from a dust suction fan 9 and a discharge port 10 arranged at the rear of the sorting chamber 8. Further, a screw conveyor 11 for transporting the first processed material from the sorting section to the outside of the machine is provided below the sorting section, and a screw conveyor 12 and a thrower 13 transport the second processed material from the sorting section. It is configured so that it is returned to the handling room 1. In addition, a threshing and sorting device for a combine harvester is configured to sort the threshed material during threshing of the harvested grain culm.

As shown in FIGS. 1 and 2, the drive shaft 14 of the handling cylinder 2 is arranged so that its rear end side protrudes upward from the receiving net 15 on the downstream side of the sorting chamber 8.
The front side wall 16 of the fuselage is formed, the plate 18 is installed on the left and right pipe frames 17a, 17b in the longitudinal direction of the fuselage, which are connected to the machine wall, and forms the rear side wall of the handling room 1; It is installed on each support member 19 extending from the pipe frame 17b. The rear side wall forming plate 18 is slidably attached to each of the pipe frames 17a and 17b, and is releasably fixed to the handling chamber forming position with a lock bolt 20, so that it can be removed from the handling chamber forming position. It is constructed so that it can be slid to a position removed from the rear end side of the drive shaft 14. Handling trunk 2
is slidably attached to the drive shaft 14 by the boss portion 2a on the front end side and the boss portion 2b on the rear end side, and rotates integrally with the drive shaft 14 by a key 21 provided on the front end side boss portion 2a. It is configured as shown in FIG. 2, and is fixed in a working position so that it can be released freely by a locking bolt 22 attached to the rear end side boss portion 2b, and is slid from the working position to a position removed from the rear end side of the drive shaft 14. It is configured so that it can be operated. The lock bolt 22 is operated through an opening with a lid 23 formed in the peripheral wall of the handling cylinder 2. Before inspecting, repairing or cleaning the receiving net 15, the top plate 24 forming the handling chamber 1 is opened, and the rear wall forming plate 18 and the handling cylinder 2 are opened as shown in FIG.
By moving it toward the rear end along the drive shaft 14, the front part of the receiving net 15 can be opened so that the handling barrel 2 does not exist above.

In addition, if the area of the sorting chamber located at the rear of the handling chamber 1 is large, the handling cylinder 1 can be moved by a stroke approximately equal to its entire length, and the receiving net 15 can be moved over the entire surface. It would be good to be able to open it up.

The plate 25 shown in FIG. 1 is used to prevent straw waste from entering between the handling cylinder 2 and the front wall 16 and wrapping around the drive shaft 14. Further, as shown in FIG. 3, this winding prevention plate 25 is removably bolted to the front wall 16 and is removably fitted onto the handling cylinder drive shaft 14 through a notch. 2 to the extent that its tip comes off the anti-wrapping plate 25 backwards, the handling cylinder 2
It can be attached and detached from between the front wall 16 and the front side wall 16.

In summary, the present invention provides the above-mentioned threshing and sorting device, in which the handling drum drive shaft 14 is installed so as to protrude upward from the receiving net 15 on the downstream side of the sorting chamber 8, and the handling drum 2 is attached to the drive shaft 14. Since the handling cylinder 2 is slidably mounted at a position away from the working position, the handling cylinder 2 can be removed from the working position by simply sliding it along the drive shaft 14. This can be done easily and quickly, and if this position change means is adopted, the 8 portions of the sorting chamber located at the rear of the handling cylinder 2 can be effectively used as a space for moving the handling cylinder 2, and the process can be done easily and quickly. Since there is no need to configure the drive shaft 14 removably, there is no need for large-scale reinforcement measures, and it is only necessary to change the drive shaft 14 to a longer one that protrudes rearward from the receiving net 15, making it easier to inspect the receiving net 15. It has become possible to construct devices that allow for efficient repair and replacement work at low cost.
