The output of 5 V of the potentiometer output 116 is applied to both terminals of the potentiometers 80a-d and 106a-d.

The operation of the embodiment will be described. A pump (not shown) in the machine room 24 of the speed sprayer 10 sucks in and sprays the spray liquid in the spray liquid tank 22, and discharges the spray liquid into the left-left nozzle pipe 38 and the left-middle nozzle pipe. Four
0, through the middle right nozzle pipe 42 and the right right nozzle pipe 44, through each pipe body 50, reaches the nozzle 26, and is ejected outward from the nozzle 26 in the radial direction of the jet head 28. Further, the blower 30 discharges the air sucked from behind to the jet head 28,
The direction of the wind is changed from the front-rear direction of the speed sprayer 10 to the radial direction of the jet head 28 by the jet head plate 34 and the vortex preventing plate 36 of the jet head 28, and is emitted from the jet head 28 outward in the radial direction.

When adjusting the directions of the nozzles 26 and the baffle plate 60, the driver reaches the front operation panel 102 in the driver's seat 20 and turns the dial 104 to rotate the protrusions.
105 is oriented in the direction in which the nozzle 26 and the air guide plate 60 are to be directed. The controller 110 sends a current to the motors 64a-d so that the input voltage from each potentiometer 80a-d is equal to the input voltage from each potentiometer 106a-d,
4a-d is reversed. The rotational power of the motors 64a-d is transmitted to the baffle plate drive link lever 82 via the sector gear 68 and the operation rod 88 to rotate the support tubes 56 of each group,
The direction of the air guide plate 60 is matched with the direction of the protrusion 105 on the operation panel 102. Further, the swinging of the drive link lever 82 for the air guide plate is performed through the interlocking rod 96.
The rotation of the untwisting pipes 52 of the pipe bodies 50 of each group is rotated to change the direction of the nozzles 26 to the projections 105 on the operation panel 102.
To the direction of. Since the direction and on / off of the supply current to the motors 64a-d are automatically performed by the controller 110, the operator simply adjusts the projection 105 of the operation panel 102 to a desired direction, and looks back. While checking the direction of the spray coming from the jet head 28, the motor 64a-
The operation of switching the supply current and the operation of turning on and off the d is omitted.

The nozzle 26 and the baffle plate 60 are each provided with a pipe body.
Since the number of nozzles 26 and the number of air guide plates 60 are fixed to the support tube 56 and the support tube 56, they can be set to appropriate numbers without depending on each other. Also, the interval between the nozzles 26 and the interval between the air guide plates 60 in the circumferential direction of the jet head 28 can be set to appropriate values individually without depending on each other.
The 60 can be of a large enough size to improve wind direction control performance. The support tube 56 does not require a untwist portion such as the untwist tube 52 of the pipe body 50, and the support tube 56
Is not of a cantilever type, and both ends are rotatably supported by a spout plate 34 and a vortex preventing plate 36, respectively, so that the support is stabilized. Furthermore, since the heavy air guide plate 60 cannot be attached to the conduit body 50, the strength can be reduced while ensuring the necessary durability.

Left-left nozzle pipe 38, middle left nozzle pipe 4
0, an opening / closing cock (not shown) is provided for each of the right middle nozzle pipe 42 and the right right nozzle pipe 44, and the left / left nozzle pipe 38 and the left middle nozzle pipe 4 are operated by operating the opening / closing cocks.
0, spraying and spraying suspension can be switched for each of the right middle nozzle pipe 42 and the right right nozzle pipe 44. Accordingly, when spraying on the left side, only the valve-opening cocks for the left-left nozzle pipe 38 and the left-middle nozzle pipe 40 are opened, and the spray liquid is sprayed only from the nozzles 26 belonging to the left-left nozzle pipe 38 and the left-middle nozzle pipe 40. I do. Similarly, when spraying upward, only the opening / closing cocks for the left middle nozzle pipe 40 and the right middle nozzle pipe 42 are opened, and when spraying to the right, opening / closing cocks for the right middle nozzle pipe 42 and the right right nozzle pipe 44. Open only.

When the upward spraying is stopped, the opening and closing cocks for the left middle nozzle pipe 40 and the right middle nozzle pipe 42 are closed, and the supply of the spray liquid to the left middle nozzle pipe 40 and the right middle nozzle pipe 42 is stopped. Not only do the left middle nozzle pipe 40
And each air guide plate 60 belonging to the group of the right middle nozzle pipes 42 is rotated until it is oriented horizontally. As a result of all the wind guide plates 60 belonging to the group of the left middle nozzle pipe 40 and the right middle nozzle pipe 42 being oriented horizontally, at the upper side of the jet head 28, a plurality of wind guide plates 60 are formed along the upper side. Then, the adjoining parts are continuously arranged without leaving a gap therebetween, and block the upper side of the jet head 28, that is, act as a wind shield plate, and stop the discharge of wind upward. Thereby, the left and right nozzle pipes 38 and / or
Alternatively, the spray liquid ejected from the nozzles 26 belonging to the right and right nozzle pipes 44 is prevented from flowing upward and being transported upward by the discharge wind. In order to make the baffle plate 60 function as a baffle plate, the lengths of the baffle plate 60 are different from each other when the baffle plate 60 is at a rotation position perpendicular to the radiation direction of the jet head 28. The setting is made so that a gap is not substantially left between the edges of the adjacent air guide plates 60.

Similarly, in the case of one-side spraying, the air guide plate 60 belonging to the group on the side where spraying is stopped is turned to a turning position perpendicular to the radiation direction of the jet head 28, and The plurality of air guide plates 60 are continuously arranged in the circumferential direction of the spray head 28, and block the peripheral portion on the side where spraying is stopped, that is, act as a wind shield plate, and discharge wind in the non-spray direction. It is stopped so that the spraying liquid sprayed from the spraying side is not discharged in the non-spraying direction.

As described above, the baffle plate 60 functions as a baffle plate. The wind guide plate 60 is disposed radially inward of the nozzle 26 at the jet head 28 and is completely submerged in the jet head 28 regardless of the rotational position. The plate protrudes radially outward from the jet head 28 to prevent the branches and leaves or the like to be sprayed from being caught while the speed sprayer 10 is running.

When adjusting the direction of the nozzle 26 individually,
This is performed by loosening the nut 27 and changing the rotational position of the nozzle 26 with respect to the untwisting pipe 52 of the pipe body 50. In addition, wind guide plate
When individually adjusting the direction of 60, it is performed by pulling out the clevis pin 62 from the pin insertion hole 58 of the support tube 56 and inserting it into another pin insertion hole 58, it is possible to switch the direction approximately 90 °, No tools are required for this switching.

Stay 100 and drive link lever 90 for nozzle
Interlocking rod 96 is freely exchanged, interlocking rod connecting bets
The de 96, by changing to a different interlocking rod 96 lengths, the ratio of the amount of swing amount of change in the wind guide plate for driving the link lever 82 and the nozzle driving link lever 90 with respect to the displacement amount of the operating rod 88 is changed As a result, the ratio of the amount of rotation of the air guide plate 60 to the amount of rotation of the nozzle 26 can be changed as appropriate.

If the rotation range of the dial 104 for changing the output voltage of the potentiometers 106a-d is increased or decreased, and the angle range in which the projection 105 of the dial 104 is directed is increased or decreased accordingly, the rotation of the nozzle 26 and the baffle plate 60 is increased. The controllable angle range of the moving position can be arbitrarily changed.

The jetting device 32 includes a left-left nozzle pipe 38, a left-middle nozzle pipe 40, a right-middle nozzle pipe 42, and a pipe system from the right-right nozzle pipe 44 to the nozzle 26 for guiding the spray liquid to each nozzle 26.
