Description

[Detailed description of the invention] This invention relates to a shell culm conveying device in a combine harvester,
The purpose is to transfer the harvested husk to the threshing device in a stable manner.

For this reason, the following technical measures were taken.

That is, a threshing device (4) having a foot chain (3) stretched along the handling opening is mounted on a chassis (2) having a traveling device (1), and a threshing device (4) is mounted on the front part of this threshing device (4). The reaping conveyance unit (8) includes a culm pulling device (5), a reaping device (6), and a culm speeding device (7) configured to transfer the reaped culm and transfer it to the foot chain (3). ), the traveling device (1) is configured to be able to be shifted by a transmission device (9), and
The foot chain (3) and at least the grain culm transfer device (7) of the reaping and conveying device (8) are provided in conjunction with the transmission device (9) so that they can both follow the vehicle speed change of the traveling device (1). The structure of the culm conveying device is such that the drive shaft θQ is interlocked with the transmission mechanism α◇.

An embodiment of this invention will be described below.

The traveling device (1) is in the form of a crawler, and has an axle α protruding from both left and right sides of a gear case installed on the chassis (2).
A driving sprocket α4 is provided on the
In order to drive and rotate the endless band uQ wound and stretched between]1
4 and a transmission (9) provided at the input section of the gear case 0 seconds, that is, the example shown is a continuously variable transmission, such as a hydrostatic continuously variable transmission mechanism (hereinafter simply referred to as H-8/RokuT). The axle 04 is configured to be interlocked so that it can move at full speed (both forward and reverse).

0 is a belt that transmits power from the engine (181) to H3T.

The threshing device (4) consists of a handling barrel (one) with a shaft (4a) suspended inside, and a foot chain (rotatably stretched along the handling opening).
3) and Karaminobe, which are conventionally well known.

The reaping conveyance unit (8) includes a cutting body holder and a grain culm lifting device (5).
, a reaping device (6), and a culm transfer device (7) consisting of a culm culm (2J) that clamps and transfers the bud end of the reaped husk culm, and a tip feed device (a) that holds and transfers the tip of the husk. In addition to being integrally constructed as a frame, each of these devices is configured to be transmission-driven so that they can rotate in conjunction with each other. Each of these devices (5)
- (6) and (7) are the output shaft ((9) of the transmission gear case (c) installed in the fuselage frame).
It is configured so that the drive can be transmitted separately by being received via seven frames.

The power transmission structure between the reaping conveyance section (8) and the foot chain (3) consists of an input shaft C20 of a transmission gear case (which serves as a drive input source for the reaping conveyance section (8)), and a frame provided at the upper end of the gear case α. The drive sprocket (c) and shaft (4) of the foot chain (3) rotatably installed on (a)
After H8T protruding from gear case @, Tsukushi, H8T
The drive shaft after being shifted by (10 is the transmission mechanism α
They are configured to be driven and rotated together via D.

Note that this drive shaft 00 is configured to be interlocked with the H8T.

This transmission mechanism 0]) consists of a belt 01) wound and tensioned between a pulley (7) provided on the drive shaft QO and the drive sprocket shaft, and a belt 01) wound and stretched between the input shaft (A) and the drive sprocket (C). It consists of a pulley 02 provided at each extending end of the shaft (a) and a belt (c) wound and tensioned between the pulleys 02.

)□ handles the driving force from the engine θ8) and the axis of the cylinder (I@) (
This is a transmission mechanism for transmitting power to 4a).

(A) is a culm transfer device that clamps and transfers the threshing culm, and is configured to be able to rotate together with the foot chain (3).

The above-mentioned belt 07)・c3]), transmission mechanism c(
4) is equipped with a clutch device that turns on and off the power transmission, and in particular, this can be done by installing it on the belt (3).

It should be noted that the foot chain (3) may be configured so that it alone can generate power.

When the engine 08) is started in the top peeling configuration,
In the traveling gear @ (1), the H3T is operated via the belt α force, and when the operator operates this, the drive sprocket (tied) rotates together with the axle shaft and the aircraft moves (can be switched between forward and reverse). )do.

On the other hand, by 000 rotations of the drive shaft, the transmission mechanism (through 1υ, the drive sprocket) (L axis (A) and input shaft (A)
By transmitting the motion J to the foot chain (
3) and the reaping conveyance section (8) are both rotated in conjunction with each other.

Therefore, as the machine advances (advance), the grain culm is divided by the cutting body (1) and pulled up by the grain culm pulling device (5), and then the base of the plant is harvested by the reaping device (6). It will be done.

The harvested grain culms are lifted up while being transported by a stock chain (2) at the base of the stock, and a stock feeder (a) at the tip end, and are taken over when they reach the starting end of the foot chain (3). It will be done.

Grain culms are transferred by the foot chain (3) while being threshed by the handling cylinder, and the waste culms are transferred to the rear of the machine by the waste culm transfer device (c).

In a series of combine harvest operations like this, the operator
When the T is shifted, when the shunting traveling device (1) is shifted to change the vehicle speed, the drive shaft a0 is also shifted in conjunction with this, so the foot chain (3) and the reaping conveyance section (8) ,
In particular, since both the shell culm transfer device (7) changes speed to follow the vehicle speed, the speed ratio between the foot chain (3) and the shell culm transfer device (7) remains constant and does not change. The grain culm can be transferred from the device (7) to the foot chain (3) in a stable posture without major disturbances in the grain culm posture.As a result, the grain culm is supplied to the threshing device (4) in a good posture and the threshing process is stabilized. It is something that can be done well.

In other words, conventionally, the speed of the shell culm transfer device (7) is changed according to the vehicle speed, but the foot chain (3) always rotates at a constant speed regardless of this. Culm transfer device (7) than chain (3)
If the speed is high, the intake of joint culms by the foot chain (3) will be slow, and the amount of grain culms that are continuously fed into the foot chain (3) will eventually be reduced to 71. There is a drawback that this transfer part may become clogged and scattered, or the posture may be greatly disturbed, making transfer impossible. In this case, the grain culm is rapidly taken in by the foot chain (3), which has the disadvantage that the grain culm posture is disturbed at the time of handing over, and the threshing process cannot be performed satisfactorily.

The present invention can overcome these drawbacks as described above.

In this invention, since the above-mentioned technical measures have been taken, even if the vehicle speed changes, both the shell culm transfer device (7) and the foot chain (3) change speed accordingly. Since the speed ratio between (7) and foot chain (3) is kept constant and no large speed change occurs between them, the husk that can be transferred from grain culm transfer device M (7) to foot chain (3) is At the time of this handover, the clogged and stagnant grain can be smoothly taken over to the foot chain (3) without greatly disturbing its posture, and as a result, the threshing process of the grain culm by the threshing device (4) can be performed well. It is effective.
