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 discharges the spray liquid in the spray liquid tank 22, and the discharged spray liquid is the left left nozzle pipe 38 and the left middle nozzle pipe. Four
After passing through 0, the right middle nozzle pipe 42, and the right right nozzle pipe 44, each nozzle passes through each conduit 50, reaches the nozzle 26, and is ejected from the nozzle 26 outward in the radial direction of the jet head 28. Further, the blower 30 discharges the air sucked from the rear to the jet head 28,
The wind is diverted 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 plate 36 of the jet head 28, and is emitted from the jet head 28 outward in the radial direction.

In order to adjust the directions of the nozzles 26 and the baffle plate 60, the driver extends his or her hand to the front operation panel 102 in the driver's seat 20 and rotates the dial 104 to project the protrusion.
Align 105 with the desired orientation of nozzle 26 and baffle plate 60. 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 to drive the motors 6a-d.

The direction of the baffle plate 60 is aligned with the direction of the protrusion 105 on the operation panel 102. Further, the swinging of the baffle plate drive link lever 82 causes the nozzle drive link lever 82 to move through the interlocking rod 96.
90, the untwisting tube 52 of the conduit body 50 of each group is rotated, and the direction of the nozzle 26 is changed to the projection 105 on the operation panel 102.
To match the orientation of. The direction and on / off of the power supply current to the motors 64a-d are automatically performed by the controller 110, so that the operator only needs to align the projection 105 of the operation panel 102 with a desired direction and look back. , While confirming the direction of the spray discharged from the spray head 28, the motor 64a-
The trouble of switching the power supply current of d and turning on and off is omitted.

The nozzle 26 and the baffle plate 60 are each a conduit body.
Since the nozzles 26 and the support tubes 56 are attached, the number of the nozzles 26 and the number of the baffle plates 60 can be set to appropriate numbers without depending on each other. Further, the intervals between the nozzles 26 and the intervals between the baffle plates 60 in the circumferential direction of the spray head 28 can be set to appropriate values individually without depending on each other.
The 60 can be a large one that is long enough to improve the performance of wind direction control. The support tube 56 does not require a twist-back portion such as the twist-back tube 52 of the conduit body 50.
Is not a cantilever type, and both ends thereof are rotatably supported by the spout plate 34 and the vortex plate 36 to stabilize the support. Further, since the heavy air guide plate 60 cannot be attached to the conduit body 50, the strength can be reduced while ensuring the required durability.

Left left nozzle pipe 38, left middle nozzle pipe 4
An opening / closing cock (not shown) is provided for each of 0, 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 respective opening and closing cocks.
It is possible to switch spraying and suspension of spraying for each of 0, the right middle nozzle pipe 42, and the right right nozzle pipe 44. Thereby, 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. To do. Similarly, when spraying upward, open only the open / close cock for the left middle nozzle pipe 40 and right middle nozzle pipe 42, and for the right spray, open / close cock for the right middle nozzle pipe 42 and right right nozzle pipe 44. Open only.

When stopping the upward spraying, 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 does the left middle nozzle pipe 40
Each of the baffle plates 60 belonging to the group of the right middle nozzle pipes 42 is rotated until it becomes horizontal. As a result of all the baffle plates 60 belonging to the group of the left middle nozzle pipe 40 and the right middle nozzle pipe 42 being oriented horizontally, a plurality of baffle plates 60 are formed along the upper side of the jet head 28 at the upper side. , Adjacent ones are arranged continuously without leaving a gap therebetween, and block the upper side of the spray head 28, that is, act as a wind shield plate, and stop the discharge of wind upward. As a result, the left and left 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 conveyed upward by the discharge air. In order for the baffle plate 60 to function as a baffle plate, the lengths of the baffle plate 60 are mutually different when the baffle plate 60 is in a rotating position at a right angle to the radial direction of the jet head 28. It is set so that there is almost no gap between the edges of the adjacent baffle plates 60.

Similarly, in the case of one-sided spraying, the baffle plates 60 belonging to the group on the side where the spraying is stopped are rotated to a rotating position at a right angle to the radial direction of the jet head 28, A plurality of baffle plates 60 are continuously arranged in the circumferential direction of the jet head 28 and shut off the peripheral portion on the side where the spraying is stopped, that is, act as a windshield and discharge the wind in the non-spraying direction. Stop so that the jetted spray liquid sneaking in from the spray side is not discharged in the non-spray direction.

Thus, the wind guide plate 60 functions as a wind shield. The baffle plate 60 is disposed radially inward of the nozzle 26 in the spray head 28, and is completely immersed in the spray head 28 regardless of the rotating position. The plate protrudes outward in the radial direction from the jet head 28 and is prevented from catching branches and leaves to be sprayed while the speed sprayer 10 is running.

When individually adjusting the directions of the nozzles 26,
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. Also, baffle plate
When individually adjusting the orientation of 60, it is performed by removing the clevis pin 62 from the pin insertion hole 58 of the support tube 56 and inserting it into another pin insertion hole 58, and it is possible to switch the orientation by approximately 90 °. No tools are required for this switching.

Stay 100 and nozzle drive link lever 90
The link rod 86 connecting the and is exchangeable, and by changing the link rod 86 to a link rod 86 having a different length, the baffle plate drive link lever 82 and the nozzle drive for the displacement amount of the operating rod 88. The ratio of the change amount of the swing amount of the link lever 90 changes, and as a result, the ratio of the rotation amount of the baffle plate 60 to the rotation amount of the nozzle 26 can be appropriately changed.

If the rotation range of the dial 104 for changing the output voltage of the potentiometers 106a-d is increased / decreased and the angular range to which the protrusion 105 of the dial 104 is directed is increased / decreased, the rotation of the nozzle 26 and the baffle plate 60 can be increased. The controllable angular range of the moving position can also be changed arbitrarily.

The spout device 32 spouts a line system from the left-left nozzle pipe 38, the left-middle nozzle pipe 40, the right-middle nozzle pipe 42, and the right-right nozzle pipe 44 to the nozzle 26, which guides the spray liquid to each nozzle 26. It is directly or indirectly attached to the plate 34 and the anti-vortex plate 36. Further, the support tube 56 as a mechanical movement part for controlling the directions of the nozzle 26 and the baffle plate 60, the motor 64a-
d, the sector gear 68, the link rod 86, the operating rod 88, the link rod 94, and the interlocking rod 96 are also the nozzle 26 and the baffle plate 60, and the nozzle plate and the duct system for the nozzle 26.
It is directly or indirectly attached to 34 and the baffle plate 36. Therefore, the spray head device 32 is manufactured as a unit and placed on the frame 12 without the restriction of assembling it on the frame 12 or manufacturing it together with the blower 30. Further, since the spray head device 32 is not restricted to be assembled on the frame 12 or assembled with the blower 30, the same spray head device 32 can be assembled to various types of speed sprayers 10.
