Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reaping part vertical movement device in a harvester.

(Prior art) A conventional traveling device is provided with an automatic feeding type threshing device on the upper part, a reaping section is provided in front of the traveling device, and the reaping section is configured to automatically move up and down by an automatic vertical movement device. The automatic vertical movement device of the reaping section is a known reaping section vertical movement device in a harvester that is configured to operate when a grain culm presence/absence sensor that detects the presence or absence of a reaped grain culm is turned on or off. That is, when the harvested grain culm runs out at the end of the field, the harvesting section is automatically auto-lifted.

(Problem to be solved by the invention) However, in the known method, if the grain culm happens to be interrupted in the center of the field, the sensor will output a signal that there is no grain culm, and therefore the field There was a problem where it mistook it for the end and auto-lifted.

(Means for solving the problem) Therefore, the present invention provides an automatic feeding type threshing device 2 on the upper part of the traveling device 1, a reaping section 3 in front of the traveling device 1, and the reaping section 3 automatically In a device configured to automatically move up and down by a vertical movement device, a reaped grain culm presence detection sensor 13 and a reaped grain culm conveyance detection sensor 14 are placed at desired positions.
The automatic vertical movement device of the front reaping section 3 is configured to operate when both the reaped grain culm presence detection sensor 13 and the reaped grain culm transport detection sensor 14 are turned on or off. The above-mentioned defects have been overcome by the structure of the reaping section vertical movement device in the machine.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. 1 is a traveling device, 2 is an automatic feeding type threshing device provided on the upper part thereof,
3 is a reaping section provided in front of the traveling device 1.

A grass cutting body 4 is provided at the front end of the reaping part 3, and a grain culm is raised behind it! 5 is provided, and behind it is a grain culm lifting #! A cutting blade 6 that cuts the root of the grain culm raised by the blade 15
A facility will be established.

7 is a raking device for raking the harvested grain culm.

Reference numeral 8 denotes a grain culm tip side conveying device that conveys the tip of the grain culm raked by the raking device N7 to the automatic feeding type threshing device 2, and 9 denotes a grain culm root portion conveying device that conveys the root portion of the grain culm. .

The reaping section 3 is connected to a piston 12 of a cylinder 11 of an automatic up-and-down movement device so that it can move upward about an axis 1O with respect to the machine body. 13 is a grain culm reaping presence/absence detecting sensor provided near the scraping device 7. Reference numeral 14 denotes a reaped grain culm transport detection sensor 14 provided near the grain culm tip side transport device 8 or the grain root portion transport device 9, and is automatically transported by the grain culm tip side transport device 8 and the grain culm root portion transport device 9. Grain culms to be conveyed to the integrated threshing device 2 are detected.

Thus, the vertical movement control box 15 that operates the automatic vertical movement device is connected to a power source via the reaped grain culm presence/absence detection sensor 13 and the reaped grain culm conveyance detection sensor 14 .

(effect) Next, the effect will be described.

When the traveling device 1 is rotated and moved forward, the weed cutting unit 4 separates the intertwined standing grain culms on the left and right sides, the grain culm lifting device 5 pulls up the hanging tips, and the cutting blade 6 removes the roots in this state. cut.

Immediately rake the cut grain culms! 7, the grain is taken over by the grain culm tip side conveying devices 8 and 9, and sent to the automatic feeding type threshing device 2 where it is threshed.

When there are no grain culms at the end of the field, the grain culm reaping presence detection sensor 13 detects the absence of grain culms and is turned on. However, since the grain culm tip conveying device 8 and the grain culm root conveying device 9 are conveying the remaining grain culms, they will not be turned on for a while and will remain off.

Therefore, the vertical movement control box 15 that operates the automatic vertical movement device is not energized, and after a short period of time, when there are no grain culms to be transferred by the grain culm tip transport device 8 and the grain culm root transport device 9. The reaped grain culm conveyance detection sensor 14 is turned on, and the vertical movement control box 15 is energized to extend the piston 12 and automatically lift the reaping section 3.

Therefore, even if the harvested grain culm presence detection sensor 13 is turned on because the grain culm happens to be interrupted in the middle of the field,
The reaping section 3 is not automatically lifted.

(Effects) As described above, an automatic feeding type threshing device is provided on the top of the conventional traveling device, a reaping section is provided in front of the traveling device, and the reaping section is automatically moved up and down by an automatic vertical movement device. In the automatic vertical movement device of the reaping section, the grain culm presence/absence sensor that detects the presence or absence of the reaped grain culm is turned on.
BACKGROUND OF THE INVENTION Devices for raising and lowering the reaping part in harvesters which are designed to be activated when turned off are known. That is, when the harvested grain culm runs out at the end of the &ti field, the harvesting section is automatically auto-lifted.

However, in the known method, the grain culm happens to be interrupted in the center of field II.

The sensor gives a signal that there is no grain culm.

As a result, there was a problem in which the end of the field could be mistaken for the end of the field and the system would automatically lift.

However, in the present invention, an automatic feeding type threshing device 2 is provided on the upper part of the traveling device 1, and a reaping section 3 is provided in front of the traveling device 1, and the reaping section 3 is automatically moved up and down by an automatic vertical movement device. In this structure, a reaped grain culm presence detection sensor 13 and a reaped grain culm conveyance detection sensor 14 are installed at desired positions
The automatic vertical movement device of the reaping section 3 is a reaping wI formed to be activated when both the reaped grain culm presence detection sensor 13 and the reaped grain culm transport detection sensor 14 are turned on or off. Since the structure of the reaping unit vertical movement device in #1 is adopted, even if the reaped grain culm presence/absence detection sensor 13 is temporarily turned on because the grain culm happens to be interrupted in the middle of the field, the reaping unit 3 will not move. It has the effect of not being auto-lifted.
