It can be moved up and down between it and B.

Note that below the separation chute 54 and the second conveyor 7,
A pair of left and right guide plates 80 are provided to guide the sieved sand between the traveling devices 3. Further, at the rear end of the vehicle body 2, a trace erasing device 88 is provided for smoothing out sifted sand, unevenness of the travel trace of the traveling device 3, etc. This trace erasing device 8B has a first rake 81・2 arms 82A, 82
This rake 81 is attached via a pin 84A. By being pivotally supported by a cylinder 84B, the cylinder 84 can be moved up and down by expanding and contracting, and it can also be pressed against a sandy ground.

A rubber sag 85 is provided on the rear side of the rake 81.

As shown in FIG.
Both the 2A and the second arm 82B have an IJ shape in plan view, and are telescopic with a cylindrical nesting part 82C. The rake 81 is pivotally connected by bins 89A and 89B, and the position of the rake 81 can be freely adjusted from the rear end of the traveling device 3. A rake 81 disposed between the rear part of the device 3 and the container 8 is capable of changing its position forward and backward.

The second arm 82B has a connecting member 82D, and a rake support rod 81A is pivotally supported by a pin 83A. ing.

In addition, instead of the rake 81 as the trace erasing member, a flat leveling plate or a rubber slop may be used. Also, when only trace erasure is expected, the rake 81 may be used as a trace erasing member. A mark erasing member may be provided.

In the above configuration, when cleaning a sandy beach, the first conveyor 6 is lowered and the tip of the scooping plate 31 of the scooping section 5 is driven forward by about 15 to 20 marks into the sand. . Then the scooping board 31 picks up the sand and dirt from the beach. The first conveyor 6 scoops up the dirt and debris together and sends them backwards to the first conveyor 6, so the first conveyor 6 scoops up the sand with each net 21, sieves the sand and dirt, and sieves the sand downward. Lift it up to the end.

The running speed of the first conveyor 6 is set to be sufficiently fast, and the garbage that has been lifted up to the rear end is thrown back when the net 2l goes around below at the drive sprocket 16. After colliding strongly with the comb rod 61, it falls onto the separation chute 54 below.

Therefore, even if wet sand is attached to the garbage 19, the impact of this collision can separate the sand from the garbage. Further, since the garbage collides with the comb rod 61 and is guided to the separation chute 54, even if the speed of the first conveyor 6 is increased, the garbage may not scatter to the rear side of the second conveyor 7. do not have.

Since the separation chute 54 vibrates up and down around the pivot shaft 56 via the connecting rod 57 due to the rotation of the disc 58, the garbage that has fallen onto the separation chute 54 via the comb rod 61 is subjected to the vibration and is The sand adhering to the sand is further sieved off by the separation chute 54. Then, the garbage is sequentially collected from the separation shoe +54 to the container 8 via the second conveyor 7.

Normally, the container 8 is placed at a receiving position C close to the second conveyor 7 with its opening 86 facing upward, and garbage is transferred from the second conveyor 7 through the opening 86 into the container 8. I'm going to put it in.

If the dust in the container 8 becomes too large, first remove the cylinder 79.
, the four-bar link 68 is extended rearward, and the opening 8
Move the container 8 from the fuselage 1 to the rear position D with the container 6 facing upward.
After being released, the rear arm 72 is raised around the pivot 78 by extension of the cylinder 79, and the container 8 is raised to the raised position B. Then, when the cylinder 71 is extended, the container 8 rotates around the axis 69 at the raised position B and is dumped, so that the garbage in the container 8 can be loaded from the opening 86 onto a truck bed or the like. can.

Garbage may be loaded onto trucks each time, but it is also possible to collect it in one place and load it later. In this case, the four-bar link 68 is connected to the arm 7 as shown in FIG.
After making it hang downward from the lower end of cylinder 7,
When the container 9 is contracted to its substantially shortest position, the position of the pivot 69 that supports the container 8 is lowered to a sufficiently low position. Therefore, cylinder 7
When the container 8 is rotated in the dumping direction along the axis 69, the rear plate 66 of the container 8 comes into contact with the ground approximately parallel to the ground. It is possible to scoop into the container 8 the garbage that accumulates in the container 8.

The container 8, the arm 72, etc. are located between the pair of left and right body side plates 4, and do not protrude outward from the body side plates 4 to the left or right, so safety during work is improved.

Furthermore, during the above-mentioned cleaning work, the tracks left and right by the pair of left and right crawler-type traveling devices 3 become dented streaks, which cause dents in the sandy beach and cause discomfort to beachgoers, as well as puddles of water, etc. It becomes a factor.

Therefore, by extending the cylinder 84 and keeping the rake 81 of the trace erasing device 88 pressed against the sandy beach, the travel trace is leveled by the rake 81. The rake 8l is placed between the rear of the traveling device 3 and the container 8, and since the view from the rear of the rake 8l is blocked by the container 8, even though it is equipped with the rake 81. The product value will not be lost due to the lack of a rake, and the container 8 will suppress the dust that is thrown up during the erasing process.

Furthermore, at the beginning of the sea opening, there may be scattered large trees etc. that are difficult to scoop up with the scooping section 5, and in such cases, the scooping section 5 is raised as shown by the symbol U in Fig. 1. The rake 81 can also be used as a so-called dozer, with a trace erasing function, by running the vehicle while it is being held, and straddling a large tree, etc. between the pair of left and right crawler type traveling devices 3. Part 82
By sliding C, the size of the foot roller portion in front of the rake 81 can be adjusted to be large or small.

Then, to remove the large trees, etc. that have accumulated in the bottom area in front of the rake 81, reduce the cylinder 84 and lift the rake 8l, and then set the container 8 in position A as shown in FIG. 5 and remove the large trees, etc. You can scoop it up.

Note that the trace erasing device 88 can be installed on the bottom of the container (packet) 8 as shown by the imaginary line in FIG. There is also a risk that dust may not be suppressed during the trace erasing work. Additionally,
The container 8 may have no loader action, but may have a dumping action from the C position in FIG.

(Effects of the Invention) The present invention is as described above, and according to the present invention, a container is provided behind the rear portions of a pair of left and right crawler type traveling devices, and a trace erasing device is provided between the containers and the rear portions of the traveling devices. During the cleaning work, which scoops up trash along with sand from the scooping section and puts the trash into a container, it is possible to level and level the ground to prevent the traces of the traveling device from forming as streak-like depressions. By doing so, you can ensure that the beach is cleaned properly.

In addition, the container can suppress dust, etc. during leveling or leveling work using the trace erasing device, so it is less likely to pollute the environment or cause discomfort to beachgoers. By blocking the rear view of the device, the commercial value of the beach cleaner is not impaired, and the bumper function of the trace erasing device can be ensured by the container.
