Description

[Detailed description of the invention] The present invention relates to a speed change confirmation device for a combine harvester.

That is, in a combine harvester that has a hoisting reaping device at the front and is driven by a traveling device, the multi-stage shifting of the hoisting and reaping device can be controlled by a shift lever, and the multi-stage shifting of the traveling device can be controlled by a traveling lever. The speed of the hoisting and reaping device is matched to the traveling speed of the device, allowing for good hoisting and reaping.The display lamp lights up or goes out only when the speed change operation of the gear lever and the travel lever match the corresponding operation position. For example, if the propulsion reaping device is operated at high speed while the traveling gear is running at a low speed, the hoisting reaping device will be checked as the machine moves forward. In order to prevent this situation from occurring, an indicator lamp is used to display the information so that it can be easily confirmed, and to ensure that the reaping is carried out accurately.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a plan view of a combine harvester with a four-row mowing structure, in which a pull-up reaping device A of a known structure is installed at the front of the machine, and this device A is installed behind two groups of weed cutting bodies arranged in the front. The device is constructed by arranging four groups of triggering bodies having tines 3 that are disposed diagonally at a low front and a high rear, and having tines 3 that can freely move in and out, and a reaping part of a reciprocating type cutting blade is disposed at the lower part of the rear side thereof. A conveying device 5 is installed at the rear of A to transport the four-row cut husk to one side of the machine body and to the rear, and a threshing device 6 is installed at the rear of the conveying device 5 to move the culm to the - side of the machine body. A cutter 7 is attached to the rear part of the machine behind it, and a driver's seat 8 is mounted on the right side of the front part of the machine next to the hoisting and reaping device A, and a control platform 10 has a group of operating levers 9 in front of it. are arranged respectively, a paddy bag placing stand 11 is arranged behind the seat 8, and an engine 12 is arranged behind it, and a track-type traveling device B is arranged at the bottom of these machines.
.

Install B in parallel.

Further, on the side of the control platform 10, a speed change lever a for changing the speed of the pulling reaping device A is arranged.
, neutral position n, medium speed position m, neutral position n, high speed position, and each position 1. n.

The actuating bodies I, -12', and the gear shift levers a are shown at m, n, and h so that they contact and operate.
On the other hand, a traveling lever b for changing the speed of the traveling device B is arranged on the side of the seat 8, and in the H-shaped guide groove 14 of the traveling lever b, the middle is in the neutral position, the four ends are in the low speed position, and the middle is in the middle position. For each forward speed position M, high speed position H, and the speed change position N for high speed traveling or reverse movement of the aircraft, each position, M
, H and N have working bodies S 1', S 2', S
3' and S4' are operated in contact with the traveling lever b, and the traveling speed of the machine and the pulling reaping speed are set at positions l, m and M when the speed change operation of the transmission lever a and the traveling lever b is performed. , h and H, n, and n and N are configured so that they can work optimally in correspondence with each other.

FIG. 3 shows a circuit diagram of each switch 42 (b) and (b).

2 and E are normally closed switches operated by the actuating bodies I', l: ]', Pa, Go and Bo, respectively, while the switches Sl, S2, S3 and S4 are operated by the actuating bodies S1', respectively. , S 2', S 3' and S 4'
15 is a battery, and 1 is an indicator lamp attached to the control console 10. Indicator lamp 1 lights up when all circuits are connected.

In addition, the configuration can be devised so that the light turns off in that state.

Therefore, in combine harvester work, shift lever a
Shift position 1. When the travel lever b is positioned corresponding to m and h, and the speed is shifted to positions M and H, the forward speed of the machine and the speed of the hoisting and reaping match optimally, and the speed change lever a is moved to the neutral position n. .

In the state where the travel lever b is in the shift position N and the lifting reaping is stopped, the machine can travel on the road or move backward.

When the gear shift lever a and the travel lever b are operated in a corresponding manner, for example, as shown in the drawing, the gear shift lever a operates the actuating body port' at the position m, and the travel lever b is at the position M. The actuating body S2' is actuated to turn the switch port and S2 into the OFF state, and the display lamp 1, which had been lit up until then, goes out, allowing the driver to confirm the correct operation status related to gear shifting. .

If this is an operation error, for example, if the gear shift lever a is operated to position M and the travel lever B is operated, the switch opening and switch S1 will only be turned OFF, but the indicator lamp 1 will not go out. Therefore, it is possible to display to the driver that he or she is unfit to operate the vehicle.

As described above, the present invention provides a combine harvester which has a hoisting reaping device A etc. in the front part and travels by a traveling device B, in which the multi-stage shifting of the hoisting and reaping device A is carried out by the gear change lever a, and the multi-stage shifting of the traveling device B is carried out. Each gear can be operated separately using a lever b, and when the gear shift lever a and the travel lever b coincide with the corresponding gear shift positions of both devices A and B in each gear shift, the indicator lamp 1 lights up or goes out. In addition, the indicator lamp 1 is not turned off or lit unless the shift lever a is in the neutral position when the drive lever b is operated to high-speed travel or reverse position N. The driver can be informed by an indicator lamp whether or not the drive lever of the combine harvester is being shifted to the optimum state for running and hoisting and reaping. The operator can also be informed and confirmed whether or not the equipment is stopped and no malfunctions have occurred, allowing the operator to accurately operate the combine in an optimal way while checking by looking at the indicator lamp. It has the characteristics of being able to perform

In addition, since the speed change lever a and the travel lever b can be operated independently, for example, when carrying out combine harvesting work on heavily lodging crops, it is necessary to be aware that the lamp display is not appropriate, and then change the speed on the hoisting device side. It has the feature that it can be used to effectively reap and harvest lodging crops by changing the relative change between the operating speed and the machine running speed.
