Of the liquid F ejected from the vegetation on the upper surface of each ridge D
To effect a washing or disinfecting action on the crop.

The liquid spouted from the side boom 4 is sprayed L and R also to the wheel tread A region and the outer region around the width region immediately below the side boom 4. Therefore, even if the washing liquid is sprayed on the crop F in the wheel tread A region by the side boom 4 and the mud is scattered from the front wheels 1 and the rear wheels 2 due to the running of the vehicle body 3, the liquid by the rear centaboom 5 is provided. Receiving the spray M, the mud attached to the crop F is washed.

Further, in the chemical spraying operation, even if the chemicals by the side booms 4 are applied to the crops in the wheel tread A area by the side boom 4 and then shaken down while the vehicle body 3 travels, the centur boom 5 can be spread.
The effect of attachment can be maintained by the application of the chemical liquid M. The liquid spray M area by the centaboom 5 is also wide on both left and right sides over the trace area of the side boom 4 and overlaps with the spray L and R areas by the side boom 4.

A front center boom 4A similar to the center boom 5 is provided along the boom holder 13,
When spraying the liquid while moving the vehicle body 3 backward, the spraying by the centtaboom 5 is stopped, and the front centtaboom 4A is stopped.
And the side boom 4 may be used to switch the spraying. In FIG. 3, the arrangement of the nozzles 11 in each of the side booms 4 and 5 is as follows.
Are three-directional nozzles 16, 17, and 18, and the nozzle 17 is directed to the front Y1 and the nozzle 17 is directed to the rear Y3 at an appropriate angle phase while the nozzle 17 is directed downward Y2 in side view. In addition, the nozzles 16 and 1 are also provided in the horizontal direction.
The directions of 7 and 18 are also out of phase. by this,
Spreading area is set wide.

4 and 5 are different from the above example in that:
A height sensor S for detecting the height of the crop F is provided at the boom holder 13 on the front side of the vehicle body 3, and the height of the boom holder 13 with respect to the hitch 12 is adjusted.
Maintain and control the crop F at a height suitable for liquid spraying. The height sensor S is a photoelectric sensor comprising left and right light emitters 19 and light receivers 20. The upper sensor is provided at a fixed upper and lower interval H on a stay 21 which is attached to the left and right ends of the boom holder 13 so as to face each other. S1 and the lower sensor S2 are mounted. From one side of the light transmitter 19 to the other side of the light receiver 2
By emitting the light beams P1 and P2 to the 0 side, the height of the crop F can be detected depending on whether or not the crop F blocks the light beams P1 and P2.

[0013] The crop F is projected light beam P of the upper sensor S1.
1, the light beam P2 of the lower sensor S2 is not detected.
When it is at the position detected only at the position (1), it is at the neutral height H and at the optimum height, and the boom holder 13 is not moved up and down. or,
When the crop F falls below the neutral interval H, the boom holder 13 is lowered by the drive of the geared motor M1 by the output from the controller, and the crop F is controlled so as to reach the neutral interval H.

Conversely, when the crop F is detected by both the light beams P1 and P2 of the upper and lower sensors S1 and S2, the boom holder 13 is raised by driving the geared motor G1, and the crop F is moved to the neutral interval H. It is controlled to come. By raising and lowering the boom holder 13, the left and right side booms 4 are integrally moved up and down together with the front sensor boom 4A, and height control is performed.

A hitch 1 is provided on a bracket 22 at the front end of the vehicle body 3 so as to be movable up and down by a pair of upper and lower parallel links 23.
