Since the movable table 20 is attached to both the projections 25, 25, the movable table 20 is restrained from moving in the direction perpendicular to the rails 11, and in the vertical direction. (See FIG. 4).

On the other hand, in order to make the movable table 20 reciprocate and traverse along the rail members 11, 11, the intervening base 12 is provided with traversing drive means. In the embodiment, the traverse drive motor 80 is fixed to the upper corner, the driving sprocket 81 is provided on the output shaft, the driven sprocket 82 is provided at the other corner, and the chain 8 wound around these is provided.

, Or the force applied to the support base 40 via the reduced force.

As shown in detail in FIG. 10 (however, it does not correspond exactly to the shape shown in FIG. 9 but is substantially the same in principle), the tip of the support base 40 is Part 4
A nozzle support 50 for supporting the spray nozzle 7 is supported at 0a. The nozzle support 50 includes a base 5
It has a turning drive motor 52 fixed to 0A, an output shaft main body 53A of the turning drive motor 52, and a support shaft 53C detachably connected thereto, for example, connected via a connection pin 53B. I have. The support shaft 53C has its base supported by a bearing 53D, is bent in the middle, and has a distal end eccentric with the axis of the output shaft main body 53A. The bending angle θ of the support shaft 53C with respect to the axis of the output shaft main body 53A is, for example, 10 degrees. A holder 55 is provided at the tip of the support shaft 53C, and supports the spray nozzle 7 directly or a rigid member connected thereto.

The nozzle support 50 thus constructed
As described above, the base 50A is supported by the distal end portion 40a of the support base 40 via the shaft support portion 40A, and the base 50A is integrated with the shaft support portion 51a of the bracket 51 integrated therewith.
By being connected to the support lifting drive cylinder 70, the entire nozzle support 50 protrudes around the axial center of the shaft support portion 40A due to the expansion and contraction of the rod. Further, by the rotation of the support shaft 53C accompanying the rotation of the output shaft main body 53A of the turning drive motor 52, the distal end of the support shaft 53C turns eccentrically with the axis of the output shaft main body 53A. As a result, the spray nozzle 7 supported by the holder 55 has a tip end opening orbiting in a circular motion locus around the axis of the output shaft main body 53A.

Each of the exercise operations of the above-mentioned spray device system can be performed by an operator who rides on the work table 4 with, for example, control devices and operation buttons and handles mounted on the work table 4.
Also, when the boom 3 of the construction machine 2 is moved, the movement control device is mounted on the work table 4 and an operator who rides on the work table 4 can perform the operation.

(Operation Mode) In the spraying operation, the operator on the work table 4 waits for the transport of the spraying material while communicating with the operator of the construction machine 2 at the butt. In this case, the positioning of the boom 3 is performed in advance by operating the movement control device or the like so that the spray nozzle 7 faces the target surface.

When the transfer of the spraying material is started, the supporting portion of the spraying nozzle holder 10 is moved in the horizontal direction along the front frame of the surrounding frame 6 by moving the movable base 20 in accordance with the target spraying speed. To make a round trip. As shown in FIG. 11, in the case of spraying between the horizontal frames F, F (or the normal frame F).
In the traversing process, the turning drive motor 52 is driven to turn the spray nozzle 7 (even in the case of the outside spraying). When a certain distance end is reached, the moving direction is reversed, or the supporting portion of the spray nozzle holding body 10 is lowered by the support lifting drive cylinder 7 to change the reverse moving path to reverse. To send. In this case, if necessary, the support base swinging drive cylinder 60 is operated to swing the support base 40 together with or without turning the spray nozzle 7, thereby swinging the spray nozzle 7. Can be swung.

In the case of shifting to spraying the upper or lower step into the lateral frame, the construction machine 2 is moved, the boom 3 is repositioned (such as the elevation angle and / or the boom expansion / contraction), or This can be performed by changing the elevation angle of the support portion of the spray nozzle holder 10 by the support elevation drive cylinder 7.

In the case of blowing into the vertical frame, the blowing nozzle 7 is moved by moving the construction machine 2 or changing the position of the boom 3 (such as the elevation angle and / or the expansion and contraction of the boom) according to the blowing speed. It can be carried out by moving in the vertical direction (the height direction of the slope). Alternatively, it can be performed by sequentially changing the elevation angle of the support portion of the spray nozzle holder 10 by the support elevation drive cylinder 7. In this vertical movement process, as shown in FIG.
To rotate the spray nozzle 7. When a certain distance end is reached, the moving direction is reversed, or the support base swing drive cylinder 60 is operated to swing the support base 40 by a predetermined angle, thereby changing the reverse movement path to reverse the movement. To send.

Further, if necessary, in this vertical movement process, the support portion of the spray nozzle holding body 10 is reciprocated in the horizontal direction at a small pitch along the front frame of the surrounding frame 6 together with the movable table 20. Thus, the spray nozzle 7 can be swung by swinging the support base 40 by swinging it into the vertical frame or by operating the support base swing drive cylinder 60.

(Others) Although not shown, for example,
Means for adjusting the direction of the spray nozzle 7 can be provided for spraying on the side surface of the legal frame. As the simplest means in this example, a turntable having a center of rotation L is provided on the base 50A, and the turntable is provided with the nozzle support 5.
In this mode, 0 is fixed.

When the construction machine is crocodile and its boom does not face the front of the slope, but faces obliquely, the work table 4 is positioned between the tip of the boom 3 and the work table 4 so as to face the front of the slope. Can be provided with a swing mechanism. Other mechanisms are
It can be easily guessed by a mechanical designer that it can be added as appropriate.

In the invention described in claims 6 to 8, the nozzle support for supporting the spray nozzle 7 can move in parallel with the slope with the spray nozzle 7 facing the slope. However, the present invention is not limited to the above embodiment. Therefore,
It is not essential to provide rocking means and prone means. For example, a guide path (for example, a rail) is simply arranged on a slope, and the nozzle support is moved by a motor or the like along the guide path, and the above-described turning mechanism is incorporated in the nozzle support. it can.

As the turning mechanism, an appropriate mechanism such as a piston crank mechanism including a piston 70 and a crank 71 shown in FIG. 12 can be adopted. Note that the circular motion trajectory of the present invention includes an ellipse. For the elliptical motion mechanism, various types of mechanics can be used as they are.

In the above embodiment, for example, the existing support shaft 53C is removed and the support shaft 53C having a different bending angle θ is brought in in response to the change in the dimension between the normal frames F, F.
By connecting this to the output shaft main body 53A via the connection pin 53B, the diameter of the turning circle can be changed, which is extremely convenient.

The tip opening of the spray nozzle 7 shows a circular locus of movement. However, when the spray nozzle 7 is turned in the course of traversing the support of the spray nozzle holder 10, the spray nozzle 7
The tip opening of FIG. 11 shows not a circular motion trajectory but a psychocolloid curve, but it is noted that FIG. 11 shows this as a set of circular motion trajectories.

[0043]

As described above, according to the present invention, a subtle and highly reliable spraying operation can be performed by allowing a worker to perform a driving operation visually in the vicinity of the spraying site. At the same time, the burden on the workers can be greatly reduced.
