Description

[Detailed description of the invention] Three pulling devices are arranged side by side in the left and right direction of the machine body so as to pull up and reap the three-row planted stem culms, and a reaping device is arranged behind them, and the three pulling devices are arranged side by side in the left and right direction of the machine so as to pull up and reap the three-row planted stem culm. The present invention relates to a combine harvester equipped with a rear conveyance device that conveys the harvested stem culms diagonally backward toward the threshing device at the rear of the machine.

Conventionally, in this type of combine harvester, as shown in Japanese Utility Model Publication No. 47-22109, for example, the stem culms that have been pulled up and harvested are once transported horizontally to near the side edge of the machine body using a horizontal transport device, and then
It was configured to be carried by a rear conveyance device and transferred to the threshing device side, but in this case, a horizontal conveyance device was required to convey the harvested stem culms laterally, which was a big loss. Not only is this necessary, but the posture of the stem culm is likely to be disturbed during the long horizontal conveyance, and the transfer direction of the stem culm is largely changed at the joint point when transferring from the horizontal conveyance device to the rear conveyance device. A swinging action occurs on the tip of the stem and culm,
The receiver may cause the transfer posture to be disturbed and the panicle to fall off.Furthermore, the receiver may cause the stem culm posture to be disturbed at the transfer point, causing the starting end of the rear conveyance device to swing up and down along the culm direction. When changing the handling depth by moving, it is difficult to pass the five sown stem culms at the starting end of the rear conveyance device, and there is a risk that the conveying posture of the stem culms will be further disturbed. .

The present invention reduces the disturbance in the posture of the conveyed stem culm by configuring the conveyance direction of the stem culm from the pulling up of the stem culm to the rear conveyance device to be along the direction of movement of the aircraft as much as possible, and also allows the conveying stem culm to move sideways. It is possible to merge stem culms and transfer them to the rear conveyance device by a simple conveyance means without using a conveyance device.Furthermore, the receiving can be performed by reducing the disturbance of the posture of the stem culm at the transfer point, so that it can be carried out by the rear conveyance device. The purpose is to provide a combine harvester in which the handling depth can be adjusted without any problems.

The characteristic structure of the combine harvester according to the present invention is that the starting end of the rear conveying device is located at the rear position of the central pulling device, and the stem culm pulled up by the left and right outside pulling devices is conveyed from both left and right sides to the rear side. A pair of left and right locking conveyance devices are arranged in a V-shape in a plan view so as to pull the conveyance device diagonally backward toward the starting end of the conveyance device, and among the pair of left and right locking conveyance devices, the rear conveyance device The lifting device corresponding to the locking conveyance device on the side along the transfer direction of the device and the lifting action portion of the central lifting device are arranged to face each other, and the rear conveyance device is arranged on the rear side of the machine body. The starting end side is configured to be swingable up and down with the vicinity of the end of the conveyance serving as a swinging fulcrum, and this structure provides the following effects.

In other words, the pair of left and right locking conveyance devices are arranged in a V-shape in plan view so that the stem culm is pulled and conveyed diagonally backward from both left and right sides toward the starting end of the rear conveyance device. The starting end of the rear conveyance device is moved while the flow of the stem culm leading to the conveyance device is shifted along the direction of movement of the aircraft as much as possible, without making a sudden change in direction from parallel to the direction of movement of the aircraft to a direction perpendicular to the direction of movement of the aircraft. It is possible to suppress the posture disturbance of the transported stem culm as much as possible.

Further, the stem culm transferred by the locking and conveying device itself moves with a certain amount of inertia.

Therefore, the above-mentioned figure 7 arrangement is advantageous in that it does not require a long horizontal feed path that causes posture disturbance, but it is advantageous in that it does not require a long horizontal feed path that causes posture disturbance. If this figure 7 is adopted, a locking and conveying device will inevitably be created that transports the stem culms in a completely different direction from the rear conveying device, and as a result, the inertial force of the transferred stem culms will cause the transfer of the stems to the rear conveying device. The stem and culm transfer posture is disturbed.

In this regard, in the present invention, among the three stalk culms that are gathered together, the stalk culm that is transferred by the locking conveyance device on the side along the transfer direction of the rear conveyance device that is transferred diagonally backward toward the threshing device side. , the stem culm pulled up by the central pulling device first merges, and when the mass of the stem culm toward the transfer direction of the rear conveyance device is increased, the remaining one stem whose transfer direction is different from that of the rear conveyance device Since the culms are merged, the transfer to the rear conveyance device side is not disturbed by the inertial force of the stem culms that are transferred in different directions.

The receiver to the thresher side uses a swinging fulcrum near the end in the conveyance direction to ensure good handover, and the start end swings vertically to avoid a large swinging range in the machine width direction. Even when adjusting the handling depth using a rear conveyance device configured to allow the rear conveyor to move, the posture of the merging stem culm at the starting end of the rear conveyance device is less disturbed, so that the right position of the stem culm in the direction of the culm can be ensured. It is possible to change the handling depth by using loquats, and even if the stem culm has a tip lag during the merging process, the stem culm will be in a posture with approximately the same degree of tip lag from both the left and right sides. As a result of the merging, after merging, the stems and culms from both the left and right sides do not cross each other, but the culms are aligned with almost the same tip-lag posture.

Moreover, the lagging direction of the tip is also along the longitudinal direction of the machine's forward direction, so when changing the handling depth, the starting end of the rear conveyance device is swung up and down along the culm. Also, the tip can be gripped securely at any position in the direction of the culm, and the handling depth can be changed without any trouble, without causing any inconvenience such as the tips coming apart and making it difficult to grip.

Embodiments of the present invention will be described below with reference to the drawings.
