Description

[Detailed description of the invention] The present invention relates to a combine harvester operating device.

That is, when reaping husk with a combine harvester, the threshing clutch is engaged to interlock the threshing device, the reaping latch is engaged to interlock the reaping device, and the hydraulic valve is operated to lower the reaping device. This must be done using the provided operating lever. This invention attempts to simplify and facilitate such operations.

The present invention takes the following technical measures for this purpose.

That is, a reaping device (1) that reaps and threshes the husk, a reaping latch (2) that is connected to the threshing device (3), and a threshing clutch (4) that is connected to the threshing device (3).
), and a hydraulic valve (5) for raising and lowering the reaping device (1).
In between, there is provided an operating device for a combine harvester, which is provided with an operating mechanism (6) that can simultaneously operate the engagement of both clutches (2) and (4) and the downward stroke operation of the hydraulic valve (5), and that can operate each separately. composition.

This invention has the following technical effects due to such a configuration. In other words, a combine harvester operates several types of operating levers in sequence to transmit power to each part to continuously reap and thresh the husks, but when starting to reap the husks, the combine must be placed in the planting row. Operation mechanism (6)
When you operate the reaping latch (2) and threshing clutch (4)
The reaping device (1) and the threshing device (3) are operated in conjunction with each other, and at the same time, the hydraulic valve (5) is switched to the downward stroke so that the reaping device (1) descends to the reaping starting position.

Therefore, reaping work can be started easily and accurately by operating the single operating mechanism (6). Also, the reaping latch (2), threshing clutch (4) and hydraulic valve (6) can be operated separately if necessary.

In addition, in the illustrated example, a reaping device (1) that can be raised and lowered by a hydraulic cylinder (7) is attached to the front of the threshing device (3).
A prime mover (8), a clutch case (9), and a gear case (10) are arranged on the − side.

A reaping latch (2) and a threshing clutch (4) are installed in parallel in the clutch case (9), and these clutches (2)
The input side of (4) connects and passes the belt to the prime mover (8) via a gear, and the output side connects the reaping latch (2), reaping device (1), threshing clutch (4), and threshing device (3). The belts are passed between the mower (8), the reaping device (1) via the reaping latch (2), and the threshing clutch (4).
The threshing devices (3) are connected to each other via the threshing devices (3).

A belt is passed through the clutch case (9) to the gear case (10), and a traveling device (not shown in the drawing) is interlocked with the prime mover (8) via the gear case (10). It is configured to change the traveling speed.

The hydraulic valve (5) is equipped with a descending solenoid (12) and an ascending solenoid (13), and is connected to a hydraulic cylinder (7) that communicates with the hydraulic pump (14) for raising oil supply, lowering oil drain, and shutting off the oil. This is a configuration in which switching is performed electrically.

The operating mechanism (6) is provided with a work switch (15), a reaping switch (16), a threshing switch (17), and an oil pressure switch (19), and when the work switch (15) is turned on, the threshing clutch is connected via a diode. (4) and the reaping latch (2) are electrically interlocked, and the lowering solenoid (12) is energized via the diode and the normally closed contact (18) to move the hydraulic valve (5) to the lowering side. The configuration is such that it can be switched. This work switch (15) may be provided at a location that comes into contact with the shift lever (11) when the shift lever (11) is operated forward.

Also, when the work switch (15) is turned off, the reaping switch (
16), the reaping latch (2) is activated by the threshing switch (1).
7), the threshing clutches (4) can be manually turned on and off, and the hydraulic switch (19) can be used to manually switch between the ascending solenoid (13) and the descending solenoid (12).

A culm sensor is connected in parallel with the work switch (15) and equipped with a delay timer that detects the presence or absence of the culm of the straw cheno (20) and turns off the power to the reaping latch (2) and threshing clutch (4). (21) is provided.

(22) is a pinching chain, (23) is a cutting blade, (24) is a power source, and (25) is a release switch.

When power is transmitted from the prime mover (8) to the clutch case (9) and gear case (10) and the work switch (15) is turned on, the threshing clutch (4) is turned on and the threshing device (3) is turned on.
The reaping latch (2) enters and transmits power to the reaping device (1), and the lowering solenoid (12) is energized to switch the hydraulic valve (5) to the lowering side so that the oil is drained from the hydraulic cylinder (7). The reaping device (1) begins its downward stroke.

When the cutting blade (23) approaches the field, the normally closed contact (18) comes into contact with the cutting blade (23), causing a cut and stopping the downward movement. Gear shift lever (11
) to move the machine forward, the husk can be reaped and threshed, and during the reaping operation, the reaping device (1) can be raised or lowered as desired by the hydraulic switch (19).

Even if the work switch (15) is turned off at the end of the work, the culm sensor (21) is activated and after the straw culm has been discharged by the straw removal chen (2o), the reaping latch (2) and Disengage the threshing clutches (4).

When the work switch (15) is turned off, the threshing switch (17)
), reaping switch (16) and oil pressure switch (19)
) can be manually turned on and off independently, and the transmission to and from the threshing device (3) and the reaping device (1) can be interrupted and the reaping device (1) can be raised and lowered.
