TECHNICAL FIELD This invention relates to the structure of reinforcement especially in the magnetic threshing apparatus mounted in a combine, harvester, etc.

If threshing is carried out for a long time, it is necessary to clean the inside of the emergency chamber because the straw straw is swept into the barrel, or the eyes of the sea are clogged, which reduces the threshing efficiency.

Therefore, as specified in Japanese Utility Model Publication No. 59-150231, the expectation structure is the division of the upper body supporting the barrel and the expectation body which forms the lower half of the dispatch chamber in a part of it. Is supporting the upper and lower swings up and down freely.

In the so-called self-throwing threshing device with a feed chain, the conveyance inlet for rice-based entry into the supply chamber and the transport outlet for rice straw discharged from the supply chamber are opened on the wall thereof, and the feed chain from the inlet to the conveyance exit is opened. Since the path for rice line-based transport is opened, the upper expectation for supporting the barrel has a so-called uniaxial support shape for supporting only the rear part of the feeding chamber.

Therefore, the threshing part during the threshing operation or the rotational action of the barrel caused the vibration phenomenon in the upper expectation, and there was a fear that the upper expectation would develop.

Therefore, an object of the present invention is to prevent the vibration phenomenon of the upper expectation in the threshing apparatus in which the upper expectation is opened and closed up and down in view of the above points.

A feature of the present invention is to construct a reinforcement frame over the upper expectation and the expected main body which bypassed the narrowing conveying path of the discharged straw straw in the threshing apparatus as described above, and the reinforcement frame is part of the upper expectation side. It is composed of the reinforcement frame part on the main body side, and the part of the above-mentioned upper base and the reinforcement frame part on the base body side are configured to be connected and released by the connecting mechanism, and its action and effect are as follows.

In the above-described configuration, in the closed state of the upper expectation, that is, in the normal working state, the vibration of the upper expectation is suppressed because the upper expectation and the rigid main body are connected through the reinforcing frame.

In addition, the reinforcement frame described above does not interfere with the discharge of rice straw, because it bypasses the discharge straw straw narrowing conveying path.

Thus, as a preferred embodiment, the part of the upper expectation side described above becomes the first reinforcement frame portion of the reinforcement frame described above, and the reinforcement frame portion of the expected main body side is the second reinforcement frame portion of the reinforcement frame described above.

In this configuration, by releasing the coupling mechanism, the reinforcing frame can be separated into the first reinforcing frame portion and the second reinforcing frame portion, so that the operation of lifting the upper base upward is possible.

In addition, since the above connection mechanism is also connected by a bolt or the like, its disconnection operation can be performed relatively easily. As described above, the vibration phenomenon of the upper expectation during threshing operation can be suppressed without greatly degrading the operability during the operation of lifting the upper expectation, thereby preventing the damage caused by the vibration phenomenon of the upper expectation.

Next, an Example is shown.

As shown in FIG. 16, the cut rice stems are threshed by the barrel 3 which is automatically supplied to the feeding chamber 2 by the threshing feed chain 1 and rotated, and the discharged straw after threshing is threshed feed chain ( The threshing unit is configured to be automatically taken out from the feeding chamber 2 by 1), and the rice straw discharged after threshing is automatically inherited from the threshing feed chain 1 by the rice straw discharge conveying chain 4 and then fallen sideways. The threshing straw discharge conveyance chamber 5 after threshing which is approached in front of the ear of ear, and is carried out to the back of a base, and is discharged | emitted and dropped is installed in the back of the operation room 2. Gravity sorting the threshing material drop-fed and supplied from the feeding chamber 2 through the water network 6 and the threshing material drop-fed and supplied from the feeding chamber 2 through the dust discharge port 7 by the drive swing type sorting device 8 is selected. And sorting into grain, dust or dust by the sorting wind supplied by the fan (9) and the dust or dust to be discharged out of the machine by the sorting wind and the exhaust fan (10). No. 1 screw conveyor (12) for discharging the threshing material from one dust discharge port (7) to discharge the first water-collected water drop-fed from the sorting device (8) out of the gas by forming the sorting unit so as to spoil the threshing treatment product from the dust exhaust port (7). In the bottom of the sorting section, a second screw conveyor 13 which carries out the second processed material drop-fed from the sorting device 8 to the transverse one side of the base is installed.

The processed material in the screw no. 13 conveyor 13 is reprocessed by the draw transfer carrier 14 having the reprocessing rotating body 14a at the place during the transfer and reduced to the upper side of the sorting device 8. By doing so, it consists of automatic threshing machine for large bunches.

As illustrated in FIGS. 1 to 4, the processing chamber 2 and threshing chamber are formed by forming the processing chamber 2 and the barrel 3 is equipped with the processing chamber entrance wall 15a and the processing chamber outlet wall 15b.
