It can be fixed in the non-working state. Reference numeral 117 denotes a transport handle, which is a planting work machine.
In addition to being used when transporting the 90, the ring-shaped engaging portion 11
7a and 117a are attached with strings 118 and 118 such as wires.
Scatter boom 93 attached and stretched by the string-like object
(2, 3) may be suspended and supported. Next, fertilizer using this granular material spreader,
A method of spraying a medicine or the like will be described. In the case of a square field, each spraying boom 93
With the (1,2,3) spread, make the aircraft reciprocate
Spray the granules. Turn the aircraft around the edge of the field
At times, bend the scatter boom 93 (2, 3)
Spraying is performed only with the program 93 (1). At that time, the scatter boom 9
3 (2, 3) bent upward (position A in FIG. 2)
Scatter boom 93 during the bending operation.
(2, 3) does not easily contact obstacles such as ridges. When the spraying operation is completed, the spraying boom 9
3 (2, 3) is bent to the position A in FIG.
So that the spraying boom 93 (2, 3) is almost horizontal.
Of each spraying boom 93 (1, 2, 3)
Adjust the angle. In this state, the spraying boom 93 (2,
The bent part of 3) is located below the elevating steps 58, 58.
On the road, in a garage, or in storage
The spraying boom does not get in the way. In the above description, the granular material sprayer is described.
As described above, a place for a sprayer for spraying liquid chemical fertilizers, etc.
In this case, the same effect can be obtained. [0056] As described above, the granules according to the present invention are
The object spreader adjusts the vertical angle of the folded spray boom
The aircraft during the spraying operation
Sometimes the spraying boom is folded upwards, driving on the road, storing, etc.
The spreader boom is almost horizontal when not working
Adjust the angle so that it projects
So that the spraying boom can be stored in a state where it does not extend
Became.In addition, the air volume of the blower that conveys particulate matter is insufficient.
If so, the feeding of the particulate matter will stop automatically,
Effectively clogs particulates in transfer hoses and spray booms
It became possible to prevent.
