Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dispersing device for distributing green material, etc., which is dispersed when paving a road.

Conventionally, this type of spraying device is placed at the rear of a spraying vehicle equipped with a tank containing the key blue material, and
A spraying device is known that is connected to the above-mentioned tank via a pump or the like and is comprised of a spray bar provided with a plurality of spraying nozzles. This spraying device uses a nozzle installed on a spray bar that is perpendicular to the direction of travel of the sprayer to spray the light blue material supplied from a tank by a pump onto the road, but the length of the spray bar is not constant. Because of this, it is difficult to change the spraying width according to the width of the road, and when spraying on roads whose widths change, there are areas that cannot be sprayed, and workers have to manually spray the areas that cannot be sprayed. The problem was that it had to be done. This hand-spraying method involves re-spraying the areas that have already been sprayed, leading to the problem of uneven spraying amounts. In addition, in order to solve these problems, even in a configuration in which an auxiliary spray bar is detachably attached to the spray bar and the auxiliary spray bar is attached or detached depending on the width of the road, the spray bar after spraying the high-temperature green material Because the spray bar is heated, it is dangerous to attach or detach the auxiliary spray bar during spraying operations. Further, this has the problem that it takes time to attach and detach the sprayer, making it impossible to change the spray width immediately. This invention was made in view of the above-mentioned conventional circumstances, and includes a plurality of spray bars in which a plurality of nozzles are arranged in parallel in the length direction, which are relatively movable in the length direction within parallel planes. When multiple spray bars overlap, the nozzle of only one spray bar sprays the growth material in the overlapped area, and the nozzles of the other spray bars can be closed by the cooperation of the spray bars. It is an object of the present invention to solve the problems and provide a spraying device capable of changing the spraying width in response to the width of the road as quickly as possible, and capable of uniformly spraying.

The present invention will be explained below based on the embodiments shown in FIGS. 1 to 6.

In the figure, the reference numeral 1 indicates a spreading vehicle, and this spreading vehicle 1 includes a tank 2 containing a green material (not shown) such as asphalt, a pump 3 connected to this tank 2, and a rear end. The section is equipped with an elevator 6 supported by a frame 5 and moved up and down by a pneumatically or hydraulically operated cylinder T.

A guide frame 8 is fixed to the lower part of the elevator (lower part in FIG. 1) perpendicular to the traveling direction of the scattering wheel 1. Furthermore, the scrubbers 9 and IQ, which are positioned in parallel, are mounted so as to be movable in the longitudinal direction.
The spray bars 9, 18' are hollow, and one end thereof is connected to the pipe 4, which is connected to the pump 3 to communicate with the spray bars 9, 18' and the tank 2, respectively. At the same time, on the side surface of one spray bar 9 opposite to the side surface facing the other spray bar 10, a nozzle 12 is fixed at one end so that the nozzle 12 is transported into the interior of the spray bar 9. with the other end facing downwards, spray bar
9 are arranged in parallel in the length direction. Inside one of the spray bars 9, there is a rod 23 that is perpendicular to the spray bar 9 and closes one end of the nozzle 12 fixed to the spray bar 9 to block the communication between the nozzle 12 and the spray bar 9. It is arranged so that it can slide in the direction. The rods 23 are slidable by a flange 21 fixed to the side surface of the spray bar 9 opposite to the other spray bar 10', and are provided with a support bag between the trod 23 and the flange 21. The nozzles 12 are normally biased and supported by springs 20 so as to open one end of the nozzles 12. Furthermore, a nozzle 1 is installed at one end of the rod 23...
2. A packing 18 that closes one end of the nozzle 12 and blocks the spray bar 9 from coming into contact with each other is fixed, and the end of the pond projects outward from the spray bar 9. There is a pin 25 inside which is normally urged outward by a spring 24 and whose movement is restricted by a cap 26 fixed to the other end of the rod 23. A portion thereof is protruded outwardly and supported by a rod 23.''. These rods 23..., packings 18..., springs 20..., 24..., flanges 21..., pins 25... and caps 26...
...is configured. On the other hand, the other spray bar 10
An opening/closing member 38 made of a plate is fixed to the side surface facing the one spray bar 9, and comes into contact with the weave of the pins 25 so as to close the rod 23 together with the pins 25. It is designed to press... Further, on the lower side surface of the other spray bar 10, one end of the nozzle army 2 is fixed to communicate with the spray bar wing Q', and this nozzle 12 is connected to the spray bar with a length of 0. A plurality of them are arranged in parallel in the horizontal direction, and the other end is positioned downward. Reference numeral 30
. . . indicates a stopper attached to the middle position of the nozzle turtle 2 . . . This thousand body 30 . This is what they are supposed to do. The ends of the above-mentioned bars 31 are rotatably connected to a single bar 32, 32, respectively, and this bar 32932 is connected to the spray bar 9,
It is movable in the length direction by cylinders 33, 33 operated by pneumatic or hydraulic pressure arranged between the bar 31 and the bar 31.
・All of them are rotated at the same time. The spray bars 9, 10' constructed in this way are movably attached to the guide frame 8 by the slide bars 16 and wings 6 fixed above them. The spray bars 9, 10 are moved independently by cylinders 13, 13 operated by pneumatic or hydraulic pressure arranged between the guide frame 8, and this movement causes the spray bars 9, 10 to move relative to each other. The effect will be explained.

The state shown in FIGS. 4 and 5 is that of the scrubbers 9 and 10.
shows a state in which they overlap over the entire length, and in this state the scattering width is the minimum.

At this time, the valve 2 provided on one spray bar 9
7... is the other spray bar 10 as shown in FIG.
When the opening/closing part village 36 presses the pin 25..., the spring 20... and the spring 24... are compressed, and the rod 2
3..., and the nozzle 12 through the packing 18.
One end of the spray bar 9 is closed to block communication between the spray bar 9 and the nozzles 12. Further, the nozzles 12 of the other spray bar 10 are closed by the movement of the bar 32, which causes the entire assembly 30 to be closed via the lever 31. Now drive the pump 3 to supply the blue material in the tank 2 to the spray bars 9 and 10, and then drive the cylinders 33 and 33 to move the bars 32 and 32 in the opposite direction to the above. Since all ten nozzles 12 are opened, the cathode material is sprayed over the entire length of the spray bar 10. However, since all of the nozzles 12 of one spray bar 9 are closed as described above, the spray bar 9 does not spray even if the stopper 30 is opened. Next, by moving the spreading vehicle 1 forward, the bonito green material is continuously spread onto the road in a width corresponding to the length of the spray bar 10. The above is the scattering using the minimum scattering width. Next, to explain the spraying on a wide road, the cylinder 13 shown in Fig. 6,
! 3, both spray bars 9, 10
to accommodate the width of the road by moving them relatively to reduce the overlapping portion.

At this time, among the valves 27 of one spray bar 9, the valve 2 of the part that overlaps with the other spray bar 10
7... are closed by the action of the opening/closing member 36 as described above, and the valve 2 of one spray bar 9 is
7..., the valve 27... in the part that does not overlap with the other spray bar 10 is released from the opening/closing member 36, so that the spring 20 and the spring 24... as shown in FIG.・The return force of rod 23... and pin 2
5 has been restored to its original state and opened. After this, the pump 2 is driven by the same machine as described above to supply the foundation blue material to the scrubbers 9 and 10, and then both bars 32, 32 are moved by the cylinders 33, 33, and the whole plug body 30...
・If opened, the roaring material can be spread across the width of the road. In this case as well, the spraying from the other spray bar is carried out over its entire length. However, the spraying by one of the spray bars 9 is caused by the valves 27 in the overlapping part as described above.
. is closed, the nozzles 27 . . . excluding the nozzles 12 . The above is the effect when spraying on wide roads. The above has explained the case where the spraying width is set in advance before starting spraying according to the width of the road, but the width of the road changes continuously and irregularly during the spraying operation. ``In order to cope with this, it is also possible to change the spray width by appropriately moving both spray bars 9 and 10 relatively even during the spraying operation.

In this case, the overlapping portion of both spray bars 9 and the amount 0 changes continuously, and in response to this change, the nozzle 12 of one spray bar 9 is also continuously opened and closed, and the spraying or its stop is changed continuously. It is done. Although the above-mentioned embodiment describes a spraying device using two spray bars, the present invention is not limited to this and may be configured with three or more spray bars.

As described above, according to the present invention, a plurality of spray bars having a plurality of nozzles arranged in parallel in the length direction are made relatively movable in the length direction in parallel planes, and the plurality of spray bars overlap each other. At that time, in the overlapping part,
Since the bonito green material is sprayed by the nozzle of only one spray bar, and the nozzles of the other spray bars can be closed by the cooperation of the spray bars, it is only necessary to move the multiple spray bars relatively. The spreading width can be changed, and the spreading width can be changed continuously in response to the changing width of the road.

In addition, in areas where spray bars overlap, only one spray bar is used to spray, and the other spray bars are automatically stopped, so there is no need to re-spray the area that has already been sprayed, and the entire area is covered. Uniform spraying can be performed across the spraying width. Furthermore, various effects such as smooth work and shortening of work time can be achieved by these.
