Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for determining vertical and horizontal cutting rows in a combine harvester.

(Prior art) A left sensor and a right sensor are provided at the rear of the tiller of a conventional combine that enters between the rows of rice, and when the left sensor and the right sensor move a certain distance between the rows, the left sensor When the right sensor and the right sensor are turned on at the same time, horizontal cutting is determined to be vertical cutting when only one of them is turned on, and after the certain distance, vertical cutting in the combine is controlled based on the result of the judgment. The determination method is publicly known.

(Problems to be Solved by the Invention) However, the above-mentioned known method has a drawback that it may run into the rows because it does not go completely straight when mowing vertically by placing the machine between the vertical left and right gaps. was there.

(Means for Solving the Problem) Therefore, the present invention provides a left sensor 6 and a right sensor 7 at the rear position of the sowing body 2 of the combine harvester that enters between the rows of rice.
When the left sensor 6 and the right sensor 7 move a certain distance between the lines, when the left sensor 6 and the right sensor 7 are turned on at the same time, the movement is horizontal, and when only one of them is turned on, the movement is vertical. In a method for determining vertical mowing and horizontal rows in a combine harvester, the method determines that mowing is being done, and after the certain distance, the control is controlled based on the result of the determination, in the case of vertical mowing, the direction is controlled even during the determination of the certain distance. The method described above was used.

(Structure) An embodiment of the apparatus capable of carrying out the determination method of the present invention will be described with reference to the drawings. 1 is a clipper-type cutting blade, 2 is a left weeding body provided in front of the blade, 3 is a central weeding body, and 4 is a right branching body, and a left sensor 6 and a right sensor 7 are respectively provided on the support rod 5 at the rear of the left branching body 2.

Further, a short sensor 9 and a long sensor 10 are provided on the support rod 8 at the rear of the right grass branch 4.

11 is a right solenoid, 12 is a left solenoid, 13 is an unloader, 14 is a power unit, 15 is a control box, 16 is a switch, and 17 is a threshing switch.

Further, 18 is a manual power switch, and 19 is a manual left switch.

Further, in FIGS. 2, 4, and 5, A indicates the left sensor, B indicates the right sensor, C indicates the long sensor, and D indicates the stock.

(effect) Next, the effect will be described.

When mowing vertically, that is, when the aircraft moves forward in the direction A in Figure 1,
Since the left-right distance T is wider than the width of the left sensor 6 and the right sensor 7, either the left sensor 6 and the right sensor 7 move forward without contacting the stock, or only one of them moves forward with contact with the stock. do. When the aircraft is moving toward the mouth, the distance t is narrower than the distance between the left sensor 6 and right sensor 7, so the left sensor 6 and right sensor 7 contact the plant at the same time, which causes vertical cutting. and lateral movement can be determined.

That is, when the judgment starts in A of Fig. 2, the left sensor 6 collides with the short sensor 9 and turns on, but the interval T
is larger than the horizontal width of the left sensor 6 and right sensor 7, so the right sensor 7 does not turn on, and the left sensor 6 also turns on the second time.
only turns on, thus giving a single right-pointing output.

As a result, the aircraft moves rightward, the right sensor 7 turns on, the left sensor 6 does not turn on, and as a result, a leftward output is given, which is repeated a second and third time.

(Effects) As mentioned above, the left sensor and the right sensor are provided at the rear of the tiller that enters between the rows of rice among the tillers of a conventional combine harvester, and when the left sensor and the right sensor move a certain distance between the rows. When the left sensor and the right sensor are turned on at the same time, it is determined that the movement is horizontal, and when only one of them is turned on, it is determined that the movement is vertical, and after the certain distance, the combine harvester is controlled based on the result of the determination. A method for determining vertically mowed rows and rows is well known. However, the above-mentioned known device has a drawback that when the aircraft moves vertically between the vertical left and right spaces, the aircraft does not travel completely straight, so it may run into the struts.

However, in the present invention, the left sensor 6 and the right sensor 7 are provided at the rear position of the sowing body 2 of the combine that enters between the rows of rice, and the left sensor 6 and the right sensor 7 move a certain distance between the rice rows. When the left sensor 6 and the right sensor 7 are turned on at the same time, it is determined that the movement is horizontal, and when only one of them is turned on, it is determined that the movement is vertical, and after the certain distance, the control is performed based on the result of the determination. In the method for determining vertical cutting rows and rows in a combine harvester, in the case of vertical movement, the direction is controlled even during the determination of the fixed distance, so the machine does not run into the row during the determination. prevent.

Claims (1)

[Claims] A left sensor 6 and a right sensor 7 are provided at the rear position of the sowing body 2 of the combine that enters between the rows of rice, and when the left sensor 6 and the right sensor 7 move a certain distance between the rows,
When the left sensor 6 and the right sensor 7 are turned on at the same time, when only one of the horizontal cutting is turned on, vertical cutting is determined, and after the certain distance, the combine harvester is controlled based on the result of the determination.
