Description

[Detailed Description of the Invention] Conventionally, when using the threshing device of a combine harvester for manual handling, the starting end of the pinching rail was separated from the feed chain, and the handling depth adjustment body was adjusted to shallow handling (depending on the model). It was necessary to widen the space for feeding the grain culm by moving it away from the feed chain by adjusting the depth of handling, and this operation was troublesome.

The present invention aims to provide a handling device for a combine harvester in which when the starting end of the clamping rail is set in the handling position, the handling depth adjusting body automatically moves away from the feed chain to provide a wide space for artificially feeding grain culms. The starting end of the pinching rail of the grain culm holding and conveying device installed along the handling opening of the threshing device is separated from the feed chain to take a handling position, and the depth adjustment body is used to handle the harvested grain culm. In the combine harvester, the starting end of the pinching rail is provided with a detector that detects when the starting end of the pinching rail is separated from the feed chain, on a member that maintains a position in which the starting end of the pinching rail moves forward and backward with respect to the feed chain. When the handling lever is set to the handling position by connecting the detector to the shallow handling adjustment circuit or the deep handling adjustment circuit of the handling depth adjustment control circuit, the display will indicate this and the handling depth will be adjusted. This is characterized in that the regulator is configured to be spaced apart from the feed chain.

The embodiment shown in the drawings will be explained below.1
is a threshing device mounted on one side of the machine,
The grain culm harvested by the reaping device 2 is transferred to the ear-side conveyor 3,
The handling depth adjuster 4 rotates diagonally up and down around the front part and pinches and conveys the stock part, and the grain is conveyed to the starting end of the pinch conveying device consisting of the feed chain 5 and the pinch rail 6 of the threshing device 1. The grains are then threshed.

The pincer rail 6 has a large number of rail pieces connected by pins, and the pins are suspended from a support frame 7 by means of suspension rods interposed with bullets, and the front end rail piece 6
A hanging rod 9 is erected by a hinge pin 8 in the middle part of a.
is loosely fitted into the support frame 7 and protrudes upward, and the handle lever 1 has a cam plate 10 at the upper end of the suspension rod 9.
A spring 14 is interposed between receiving plates 13, 13, whose bases are rotatably connected by a pin 12, and which are brought into contact with the lower surface of the support frame 7 and the boss portion of the hanging rod 9.

Further, the control circuit 15 of the handling depth adjustment body 4 includes a handling depth adjustment signal output unit 16 consisting of a handling depth sensor or a manual switch that detects the tip of the grain culm to be transferred and detects the rod length; The automatic handling depth circuit 17 is operated by the output, and the motor 18 rotates forward and backward to make the handling depth adjustment body 4 go up and down. ), and the automatic handling depth circuit 17 and the motor 18 are each connected to a relay 1.
Deep circuit 21 and shallow circuit 2 with 9 and 20
The relays 19 and 20 are connected by the deep handling signal or the shallow handling signal from the automatic handling depth circuit 17, and either one of them closes from the open state as shown in FIG. 18 rotates forward or backward.

23 is an upper limit switch for handling depth; 24 is a lower limit switch; 19a and 20a are relay coils.

A hand-operated switch 25 is provided on the front upper surface of the support frame 7, and is turned on when the hand-held lever 11 is rotated from the normal position shown in FIG. 2 to the front as shown in FIG. At this time, the rail piece 6a has been pulled up and is far away from the feed chain 5, and the manual switch 25 is connected to the shallow handling circuit 22 by an electric line 27 having an indicator 26 consisting of an indicator light.

Note that the display 26 is attached to an operation panel 28 provided at the front of the other side of the machine.

In the above-mentioned apparatus, when performing normal reaping and threshing work, the hand lever 11 is tilted backward as shown in FIG. rail piece 6a
is pulled up and the manual switch 25 is turned on, the display 26 is lit and at the same time the relay 20 is turned on.
closes and the motor 18 rotates in the shallow handling direction, which causes the handling depth adjuster 4 to rotate downward until the lower limit switch 24 is turned off. can be easily supplied to the starting ends of the feed chain 5 and the pinch rail 6, and the handling depth adjuster 4 does not become an obstacle, making it safe.

Also, when you finish the manual work and start the reaping work,
Even if the operator forgets to return the handling lever 11, the display 26 informs the operator that the rail plate 6a is in the handling position.

Next, an example in which the pretreatment clutch is engaged and does not operate when the manual lever 11 is in the manual handling position will be explained with reference to FIGS. 4 and 5. 30 is a drive pulley;
is a pre-processing input pulley, and a clutch pulley 33 installed opposite to a belt 32 hung on the pulleys is pivotally supported on a swinging arm 34, and a lever 35 protruding from the boss portion of the arm 34 is connected to the pre-processing clutch lever 3.
6 and the lower end of the wire 38 from the handling lever 11, the clutch is movable up and down and fixed to the clutch by nuts 39, 39 so as not to come off, and is pulled and biased by a spring 40 toward the clutch engagement side.

Figure 4 shows the manual lever 1 for reaping and threshing work.
1 to the rear, and the pretreatment clutch lever 36 is set to the engaged position.In this state, when the handling lever 11 is rotated forward and brought down to carry out manual handling, the rail piece 6a is pulled up and the wire is removed. 38
pulls up the lever 35 and loosens the belt 32, cutting off power transmission to the pre-processing section, and the handling lever 11 side of the wire 38 moves below the pin 12, causing the pre-processing to be inadvertently driven during manual handling work. It is safe without any problems.

Even if the pretreatment clutch lever 36 is set to the engaged position without returning the manual lever 11 to the rear after completing the manual handling operation, the wire 38 is not connected to the pin 1 as shown in FIG.
2, it remains in tension, and the clutch pulley 33 does not tension the belt 32 by simply lowering the rod 37, and the pretreatment section does not drive, so the manual lever 11 must be reset. I never work without doing anything.

When the manual lever 11 is returned to the position shown in FIG.
It operates according to the operation of the controller, and the power is interrupted.

Figures 6 and 7 show that when the hand lever 11 is set to the hand position, the pretreatment clutch is automatically disengaged.
Furthermore, when the pretreatment clutch lever 36 is set to the engaged position with the hand lever 11 set in the hand position, the hand lever 11 automatically returns to the non-hand position in conjunction with this. Then, the outer stop 4 on the handle lever 11 side of the wire 38
0' is attached to the stay 41 and the handling lever 11 is set in the handling position as shown in FIG. When the processing clutch lever 36 is set to the engaged position, the handling lever 11 is pulled by the wire 38 and returns to the non-handling position.
Furthermore, when the pretreatment clutch lever 36 is in the engaged position, when the handling lever 11 is rotated forward to take the handling position, the wire 38 pulls up and rotates the lever 35, causing the clutch pulley 33 to retreat and the belt 32 to move forward. relax.

8 and 9 show an example in which the hand lever 11 and the straw discharge device 52 of the straw cutting device 51 are interlocked and connected, and the straw cutting device 51 is usually attached to a combine harvester.
The cut straw is scattered over the field one after another as the machine advances, but if it is handled manually in a fixed position, the cut straw will accumulate at the bottom of the straw cutting device 51 and become clogged, so this is an improvement on that point. It consists of a scraping wheel 53 and an opening/closing plate 54, each having a length approximately equal to the width of the disk-shaped straw cutting device 51 of the straw discharging device 52, and is attached to the end of the shaft of the scraping wheel 53. The pulley is driven by a pulley on a shaft 55 equipped with a rotary blade via a belt 56, and a clutch pulley 5 disposed opposite to the belt 56 drives the pulley via a belt 56.
The swing arm 58 of No. 7 is operatively connected to the handling lever 11 via a wire 59.

Therefore, when the hand lever 11 is placed in the non-handling position as shown in FIG. 8, the belt 56 is relaxed and the scraping wheel 53 does not rotate, but when the hand lever 11 is placed in the non-handling position as shown in FIG. When set in the posture, the wire 59
pulls the upper part of the swinging arm 58 forward and presses the clutch pulley 57 against the belt 56, so the scraping wheel 53 rotates and scrapes out the straw that is to be accumulated rearward. At this time, the opening/closing plate 54 is left open.

Figures 10 to 12 show the use of the flasher lamp of a combine harvester for illuminating manual handling work at night.
When inserted into the electric circuits 0 and 60 and the hand lever 11 is set to the hand position, the flasher lamps 60 and 60
lights up.

These flasher lamps 60, 60 are usually provided on the upper front surface of the support frame 7, so when they are turned on, the part that supplies the grain culms is illuminated and can be easily handled even at night.

In the drawing, 61 is a main switch, 62 is a flasher unit, and 63 is a flasher switch.

As described above, the present invention is characterized in that the starting end of the pinching rail of the grain culm clamping and conveying device installed along the handling opening of the threshing device is separated from the feed chain to take a handling posture, and the harvested grain culm is handled by a depth adjusting device. In a combine harvester configured to supply feed to a feed chain through When the handling lever is set to the handling position by connecting the detector to the shallow handling adjustment circuit or the deep handling adjustment circuit of the handling depth adjustment control circuit, the handling depth adjustment body is separated from the feed chain. With this structure, when the hand lever is set to the hand handling position and the starting end of the pinching rail is moved away from the feed chain, the handling depth adjuster automatically moves away from the feed chain, making it easier to operate the hand lever. A state that is easy to handle can be obtained extremely easily and quickly just by using the following methods.
