Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a low cutting positioning device for a combine harvester.

(Prior art) Conventionally, a manual operation lever lowers the reaping section via a vertical movement device when operated in the lowering direction, and an O lever when the reaping section touches the ground.
A ground sensor is installed to move the reaping part upward as it becomes N.
It is known that the reaping section is moved upward when the ground sensor is turned on during the lowering operation using the manual operation lever.

(Problem to be Solved by the Invention) In the above-mentioned known device, when the ground sensor is turned on even when the manual operation lever is outputting the lowering output for moving the reaping section downward, the raising output of the grounding sensor is prioritized and the reaping is performed with priority. It is technically difficult not only to move the culm up, but also to move it to a lower position, which is why it is extremely difficult to reap culms that have fallen down below one plant.

That is, the reaping operation of the lodging shell culm requires manual operation 1±1 to lower the reaping section to below the lodging shell culm, and the work must be carried out in that state.

However, in the following way, the difficult work described above can be done inside the cylinder.

(Means for Solving the Problem) Therefore, the present invention provides a manual operation lever that lowers the reaping section l via a vertical movement device when operated in the lowering direction, and a manual operation lever that lowers the reaping section l when operated in the downward direction.
When it touches the ground, it turns ON and the reaping section 1tt, h! In the device equipped with a ground sensor 5, the lowering output of the reaping section 1 by the manual operation lever is controlled by the lowering output and the ground sensor so that the lowering output of the reaping section 1 by the manual operation lever is stopped and fixed when the ground sensor 5 contacts the ground T and turns ON. This is a device for determining the low reaping position of the reaping section in a combine harvester in which the reaping section and the reaping section 5 are connected to each other.

(¥Example) An example of the present invention will be described with reference to the drawings. 1 is an automatic feeding type threshing machine! This is the reaping section of a combine harvester with an It position and a running device list.

The reaping section l is connected to the traveling device J:'FI! It is mounted so that it can move up and down via the lJ device. The F drive device is 1M
It is operated by a manual operation lever 2 provided at the seat changer.

Reference numeral 3 denotes a cutting body of the cutting section 1, and a pulling device 4 is provided behind it, and the culm pulled up by the pulling device 24 is harvested by a cutting blade at the rear thereof. A grounding sensor 5 is provided on the lower surface of the grass dividing body 3. When the ground sensor 5 comes into contact with something, it turns on and outputs a raising output to move the reaping section 1 upward by the vertical movement device.

Therefore, the L movement control of the reaping section 1 by the ground sensor 5 and the hand! ! The relationship between I+control lever 2 and cutting height control is 1
When the ground sensor 5 is turned ON while the manual operation lever 2 is outputting a lowering output to move the reaping part l downward,
The downward movement of the reaping section 1 by the manual operation lever 2 is stopped, and the reaping section 1 is moved forward as it is, and the fallen culm is raised and reaped.

Note that the reaping M1 is controlled by the reaping section 1 using the manual operation lever 2.
While outputting a lowering output to lower the ground sensor 5 is ON.
In this state, it moves forward, but f-ePj
When t is released from the operating lever 2, the reaping part 1 moves upward until the ground sensor 5 turns ON and turns OFF.

(Effect) Next, the effect will be described. f Operate the manual operation lever 2 to position the reaping part l at the desired height and move the machine forward.The body 3 will separate the intertwined culms on the left and right sides in one minute, and the pulling device 2! Pull up the hanging tip with t4, cut the root with the cutting blade,
ll &``r'' raking device, root side conveyance device, tip side conveyance 9F! Conveyed by I and handed over to the culm feeding device, automatic feed type threshing 92! Thresh within i.

A ground sensor 5 is provided on the lower surface of the grass body 3, and when the ground sensor 5 comes into contact with the ground, it is turned on and outputs a raising output, so that the reaping unit 1 is moved -L by the vertical movement device.

However, when reaping a lodging shell culm, the reaping section can be positioned simply by lowering it below the lodging shell culm using a manual operation lever.

When the manual operation lever 2 outputs a lowering output that moves the reaping section 1 downward, the reaping section 1 is grounded and the grounding sensor 5 is activated.
is turned on, and in connection with this, the position of the reaping section l is fixed.

Therefore, positioning for low mowing can be easily performed.

Therefore, while the lowering output of the manual operation lever 2 is being outputted, the height at which the ground sensor 5 is turned ON continues, so when the reaping unit 1 is moved down to the base of the lodging culm, the ground sensor 5 is turned ON. Since the reaping unit 1 does not move even when the culm reaches the point where the culm reaches the end, the reaping operation of the lodging culm can be carried out accurately.

(Effects) Conventionally, when operated in the lowering direction, the t-motion operating lever lowers the reaping section via a vertical movement device, and when the reaping section touches the ground, it lowers the reaping section.
A ground sensor is installed to move the reaping part to N and move the reaping part to L.
The ground sensor is O during the lowering operation using the manual operation lever.
There is a known device in which the reaping section is moved upward when the condition becomes N.

In the above-mentioned known device, when the ground sensor is turned on even when the manual operation lever is outputting a lowering output to move the reaping part downward, the raising output of the grounding sensor takes priority and not only moves the reaping part upward, but also lowers the output. It is technically difficult to manipulate the culm into position, which is why it is extremely difficult to reap the culms that have fallen down from the base of the plant.

That is, when reaping a lodging shell culm, the reaping section must be lowered to below the lodging shell culm using a manual operation lever, and the work must be carried out in that state.

However, the present invention has a manual operation lever that lowers the reaping section 1 via a vertical movement device when operated in the lowering direction, and a grounding sensor 5 that turns on when the reaping section 1 touches the ground and moves the reaping section I upward. In this case, the lowering output of the reaping section 1 by the manual operation lever is stopped and fixed when the ground sensor 5 comes into contact with the ground or the like and turns on.

Since the lowering output and the ground contact sensor 5 are connected to the reaping section low mowing positioning device for a combine harvester, the reaping section can be easily set at a low mowing position, and accurate low mowing can be achieved.
