Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is configured to detect the left and right relative positions of the planted stem culm row and the machine body, control the traveling direction, and automatically follow the planted stem culm row for reaping. Concerning a reaper with an automatic controller.

The above-mentioned reaping machine is configured to automatically correct the machine's course immediately when reaping is completed in one direction or when the planted stem culm rows are unevenly planted, so that the operator can perform efficient work without putting a burden on the operator. However, there is a risk that the aircraft will overturn during automatic turning because the operator cannot maintain the stability of the aircraft during turning.The present invention solves this problem and provides a safe and highly efficient system. The purpose is to carry out reaping work.

The present invention provides the above-mentioned reaping machine with an automatic control mechanism,
The vehicle is characterized in that the relative position detection mechanism, the direction control mechanism, and the travel speed control mechanism are interlocked so as to perform high-speed straight travel and low-speed turning travel.

In other words, when making a turn to change the direction of travel, the machine not only automatically travels at a low speed to eliminate the risk of the machine falling over, but also operates at high speed while going straight to perform mowing work with high efficiency.
It has been possible to prevent damage to the machine body due to a fall accident and perform automatic and efficient reaping safely and without bothering the operator's supervision.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

FIG. 1 shows the entire binder, and is constructed so that a lifting section is provided at the front and a binding device 2 is used to bind and release the harvested stem culms to the side of the machine body.

An engine 1 is mounted behind the front lifting reaping section 1, and a single running wheel 4 is provided at the front of the engine 1. It is configured to be rotatable around a pivot axis 1 that is perpendicular to the top and bottom, and to change the direction of movement.

FIG. 3 shows the structure of the direction control mechanism T and the running speed control mechanism T of the binder, and the sensor 8, which is swing-displaced in the front-back direction and is energized to swing forward, is pulled up in front of the reaping section 1. It is configured to detect the relative position between the planted stem culm row and the direction of movement of the aircraft.

This sensor 8 and the angle changing fork 9 of the running wheel 4 are interlocked and connected by a linkage mechanism 10.

With this configuration, the sensor 8 is in a state where it is in contact with the root of the planted stem culm existing near the center of the width of the planted stem culm introduction path of the 6-up cutting section 1 and is oscillatingly displaced. At, running wheel 4
is parallel to the longitudinal direction of the aircraft and is configured to run straight ahead, and as the rocking displacement position of this sensor 8 shifts from side to side, the running wheels 4 are tilted in the direction of the shift in plan view, and the aircraft is Turn and change direction.

The system is such that the planted stem culm is always automatically positioned near the center in the width direction of the introduction path and harvested.

The system is configured so that the entire field is automatically mown in a circular motion following the planted stem culms.

Further, the end of a wire 12 connected to the throttle lever 11 of the engine 1 is connected to the fork 9 with some flexibility, so that when the running wheel 4 deviates to the left or right by a certain angle from the straight-ahead position, the A traveling speed control mechanism 2 is configured in conjunction with the direction control mechanism t so that the throttle lever 11 is started to be pulled, the rotational speed of the engine 1 is decreased, and the traveling speed is decreased as the turning radius becomes shorter. .

In addition, with combine harvesters and two-wheeled binders,
The sensor 8 is interlocked with the running clutch.

Additionally, the throttle lever 11 may be pulled in conjunction with the operation of the running clutch to reduce the traveling speed.

It is also good to automatically control the speed based on the detection results of the planted stem culm row and the machine body.

In this case, it may be a good idea to reduce the speed immediately before starting the direction correction.

It is also preferable to reduce the speed and correct the direction at the same time.

It is also good to reduce the speed immediately after starting the direction correction.

Further, the speed may be increased at the same time, immediately before, or immediately after the start of straight running after the direction correction.

Note that although numbers are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
