Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pest control work machine for a mobile agricultural machine, and more specifically, a pest control work machine is mounted on a traveling machine body, and a long length in the left-right direction is provided on the pest control work machine. The present invention relates to a control work machine for a mobile agricultural machine that sprays a liquid material from a boom.

[Conventional technology]

Generally, a work machine mounted on a tractor or the like is provided with a long boom in the left-right direction at the rear part of the machine body, and a so-called boom sprayer or the like that sprays a liquid material such as a medicine from a long boom toward a crop in a wide range. Pest control machines are known.

[Problems to be solved by the present invention]

However, in this type of pest control work machine, since the long boom greatly protrudes to the left and right sides of the machine body, there is a risk that the long boom may come into contact with the ridges or the like and be damaged when turning in a headland. Even when the aircraft was stored indoors, there were problems such as the long boom obstructing it.

The present invention was devised in view of the above-mentioned circumstances, and is capable of spraying a liquid material over a wide range from a long boom in the left-right direction provided in a pest control work machine, and at the time of turning traveling in a headland. The long boom does not come into contact with ridges or the like and is not damaged, and the long boom does not get in the way when the aircraft is stored indoors, so it can be easily stored even in a narrow space. It is an object of the present invention to provide a control work machine for mobile agricultural machines.

[Means for solving the problem]

The technical means taken by the present invention to achieve the above object is to install a pest control work machine on a traveling machine body, and to spread the liquid material from a long boom in the left-right direction provided on the pest control work machine. In the above, the long boom is configured to be horizontally foldable toward the side surface of the traveling machine body, and the traveling machine body is provided with a detection mechanism for detecting whether the machine body is in a working position or a non-working position. The folding operation of the long boom is linked to the detection result of the detection mechanism, and the long boom is folded into a non-working posture at the headland turning point and the headland traveling portion.

[Function of device]

The detection mechanism detects whether the current position of the traveling machine is in a workable process or a non-working process, and the long boom is automatically folded when traveling in the headland turning point or headland which is a non-working process. The long boom in the working state does not touch the ridges.

Gauge wheel 51 while driving
Is to detect the distance traveled by rolling in a field scene. Reference numeral 53 is a position sensor of the pest control work implement 13, and the position sensor 53 may detect the landing condition of the gauge wheel 51.

When the traveling mechanism 1 goes straight ahead and detects a headland when the detection mechanism 49 detects that it is a workable process and performs the control work, the predetermined turning point is reached based on the distance detection of the gauge wheel 51. Turn the aircraft 90 degrees, then make another 90 degrees at the next turning point after traveling a certain distance on the headland.
The headland is evacuated after turning the vehicle once in a traveling direction opposite to the original traveling direction, but by linking the folding operation of the long boom 26 with the detection result of the detection mechanism 49, the headland turning point and When traveling on a headland, the long boom 26 is folded so as to be in a non-working state.

In the above-mentioned configuration, when performing the pest control work, first, when the control of the work implement is in the manual mode, it is non-working, and in the automatic mode where the work implement automatically performs work, or in the case of wireless control, first, The position sensor 52 of the detection mechanism 49 detects the landing condition of the gauge wheel 49, and if it has landed, at the positions indicated by process Nos. 1, 2, 7, and 8 in FIG. A liquid material such as a medicine is sprayed from the shaku boom 26 to perform a work operation. That is, first in the process No. 1, the beam sensor 10 goes straight while detecting the crop strip, and moves No. 2 to a predetermined turning point No. 3 based on the distance detection of the gauge wheel 51 for detecting the headland. Then, the stick 7 raises and lowers the aircraft to change the traveling direction by 90 degrees, travels along the headland along the process No. 4, and then at the next turning point No. 5, further changes the direction by 90 degrees and escapes the headland. At this time, linked to the detection result of the detection mechanism 49, the long boom 26 is folded at the turning point No. 3, and it is in a non-working state to travel on the headland, so the long boom 26 contacts the ridges and the like. This can prevent the risk of damage. Then, when the headland escapes along No. 6 and the work becomes possible again, the long boom 26 projects to the left and right and goes straight through the process No. 7 to perform the work operation, and when the other headland is reached, the process No. .8,
At the positions 9, 10, 11 and 12, the vehicle turns and runs in the same manner as in the above-mentioned step Nos. 2, 3, 4, 5 and 6, and thereafter, the same operation can be repeated to smoothly carry out the pest control work.

When the long boom 26 is in the non-working state, the long boom 26 is folded after the opening / closing valve 40 is closed, and when the long boom 26 is in the working state, the long boom 26 is projected and then the opening / closing valve 40 is closed.
The liquid is prevented from being accidentally splashed during the operation of the long boom 26 because the opening is opened.

Further, since the long boom 26 is folded in the horizontal direction, even if the reaction force of the sprayed liquid material acts on the long boom 26 upward, the long boom 26 does not move up and down. Moreover, since the mounting boom 25 equipped with the long boom 26 can be vertically rotated and slid forward and backward, the long boom 26 can be easily adjusted to an appropriate position corresponding to the growing state of the crop a. it can.

On the other hand, even when the machine body is stored indoors, folding the long boom 26 enables easy storage even in a narrow space.
