The scooping section 5 is for scooping up dust as well as sand, and is constructed by installing a scooping plate 28 in the left-right direction between side plates 27 fixed to the front end of the conveyor frame 13.

A sweeping rotary body 29 is provided in front of the scooping part 5, and this rotary body 29 transmits the rotation of the motor 30 to the transmission body 31.
and is rotated in the direction of arrow A in FIG.

As shown in FIG. 1, this sweeping rotary body 29 has tines 33 made of elastic rods protruding radially from the corners of a rectangular drum 32 and arranged in large numbers in the left and right direction of the scooping plate 28. The tines 33 have a winding part 34 in the middle to serve as an elastic force storage part, and the tips of the tines 33 have a sweeping part 35 bent in the opposite direction to the rotating direction. The rotation locus of the sweeping section 35 is configured to overlap the upper surface of the scooping plate 28 in the front-rear direction.

The drum shaft of the drum 32 is rotatably supported by a pair of left and right support stays 37 which are vertically movably supported by a pivot shaft 36 provided on the body 1 side, and the pivot shaft 36 is configured to sweep and rotate. Support stays 39 that rotatably support gauge wheels 38 disposed on the left and right outer sides of the body 29 are pivotally supported on a common shaft.

Therefore, under normal conditions, the elastic support means 40, 41 support the sweeping rotary body 29 in a balanced manner via the support stay 37, but when an overload is applied to the sweeping rotary body 29, the resilient means 40, 41 must be moved upward to avoid it. It is set to rise.

Furthermore, by providing a reciprocating telescopic cylinder 50 on the support stay 39 and the machine body side, the sweep rotary body 29 can be vertically oscillated together with the gauge wheel 38.

In FIG. 2, the second conveyor 7 is for receiving the garbage lifted by the first conveyor 6 and throwing it into a container (packet) 8 while removing the sand. A drive shaft and a driven shaft are installed between both ends of the conveyor frame 51, and a drive sprocket 52 is fixed to each shaft.
A chain is wound between the driven sprocket 53 and the driven sprocket 53, and the chain is provided with a net or a crosspiece, and the driving sprocket 52 is driven by a transmission body 54.

A sufficiently large head is provided between the rear end of the first conveyor 6 and the front end of the second conveyor 7, and a separation chute 55 is arranged in the middle of the head.
This is to separate sand from the garbage falling from the conveyor 6 to the second conveyor 7, and is composed of a net, stack rods, etc.

Near the outside of the rear end of the first conveyor 6, the entire width between the side plates 4 is arranged so that garbage, clods of earth, etc. thrown backward from the first conveyor 6 collide and fall onto the separation chute 55. A stacking rod 56 is provided, and the lower end of the stacking rod 56 is supported by a support member 57 installed between the rear ends of the conveyor frame 13, and the supporting member 57 has a guiding rod 56 extending downward. 58 is installed.

The container 8 shown in the packet has a front plate 59, a side plate 60, and a rear plate 6.
1 and a bottom plate 62, and the rear plate 61 has a blind plate shape to prevent sand attached to garbage from flying backwards, and a blade plate is provided at the edge on the opening 63 side. , also the front plate 5
9, a net is attached to each frame of the side plate 61 and the bottom plate 62.

The container 8 is arranged at the rear of the crawler-type traveling device 3, and each side plate 60 is pivotally attached to four-bar links 64 on both the left and right sides with a pivot 65, and a fixed link 66 at the tip of the four-bar link 64
By expanding and contracting a dump cylinder 67 provided between the side plate 60 and the side plate 60, a dumping operation can be performed around the pivot shaft 65.

Each four-bar link 64 is pivotally connected to the rear end of a pair of left and right lifting arms 68 arranged between the side plate 4 and the conveyor frame 51, and a bracket 69 fixed to the lifting arms 68,
A cylinder 72 is interposed between a bracket 71 fixed to a link 70 of the four-bar link 64.

Each lifting arm 68 is pivoted at its front end side by a pivot installed between the left and right side plates 4 so as to be able to rise and fall freely, and each arm 68
A lift cylinder 73 is interposed between the bracket and the bracket of the vehicle body 2. And four-section link 64
can swing back and forth by the expansion and contraction of the cylinder 72, and the lifting arm 68 can move the packet (
The container) 8 can be moved up and down between a ground position where the rear plate touches the ground and an elevated position above it, and can be dumped.

Further, at the rear end of the vehicle body 2, a trace erasing device 74 is provided for smoothing out sifted sand, unevenness of the travel trace of the traveling device 3, etc.

Furthermore, a first roller including a sweeping rotary body 29, a gauge wheel 38, etc.
The conveyor 6 can be supported in a rollable manner relative to the vehicle body 2.

In other words, as shown in Figure 3A, a pair of left and right telescopic cylinders! 75 and 76, the first conveyor 6 is supported by the car body 2 so as to be able to roll freely, and a horizontal sensor (not shown) regarding the left and right direction is provided on the car body 2 or the first conveyor 6 side, so that the work surface G is as shown in FIG. When the ground is on a slope as shown in B, the scooping section 5 including the scooping plate 28 is made parallel to the inclined work surface G1 by expanding and contracting the telescopic cylinder devices 75 and 76 in response to the signal from the horizontal sensor. , even on the inclined work surface G1, it is possible to scoop up and collect garbage.

In the above configuration, when cleaning a sandy beach, the first conveyor 6 is lowered and the tip of the scooping plate 28 of the scooping section 5 is driven forward into the sand by about 15 to 20 ca+. Then, the scooping plate 28 scoops up sand and garbage from the beach, and they are sent backward to the first conveyor 6, so each conveyor 21 of the first conveyor 6 scoops up the sand and garbage. The sand is sieved downward and lifted to the rear end.

In this operation, the plunging depth of the scooping plate 28 is set by the left and right pair of gauge wheels 38, which is caused by the expansion and contraction of the cylinder device 50, which moves the support stay 39 into the pivot 36.
This is done by swinging up and down around the .

On the other hand, the sweeping rotary body 29 has upper and lower elastic holding means 40°41
Since it is elastically supported by the side plate 27 and the support stay 39, the sweeping depth can also be adjusted.

The dirt in the sand is forcibly sent to the scooping section 5 by the rotation of the sweeping rotor 29 in the direction of arrow A, and is scooped up by the scooping plate 28 without being transferred to the conveyor 21. The dirt and the like that have accumulated therein are also reliably transferred to the conveying tool 21 by the rotation of the sweeping rotary body 29.

Further, each tine 33 of the sweeping rotary body 29 has a winding portion 34.
Therefore, even if the sweeping part 35 enters during crushing, its elasticity prevents it from breaking, and since the sweeping part 35 is bent in the opposite direction to the rotating direction, the sweeping part 35 is prevented from breaking. There is no upper and lower elastic support means 40.41 in the normal state.
This allows you to sweep while keeping your balance.

On the other hand, when an abnormal load is applied to the sweeping rotary body 29 due to a large amount of dirt, etc., the support stay 37 rises against the springs 44 to avoid the load.
assists the support stay 37 to rise.

When overload is avoided, the support stay 37 is lowered by the action of the spring 44, and the support stay 37 comes to rest at a position balanced with the spring 45.

Therefore, it is desirable that the spring holder that allows the spring force of the spring 44.45 wound around the rod 42.43 to be freely inserted into and removed from the rod 42.43 can be adjusted by changing the position of the pin.

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 conveyor 21 goes around to the bottom at the drive sprocket part 6. After colliding strongly with the stacking rod 56, it falls onto the separation chute 55 below.

Therefore, even if wet sand is attached to garbage, the sand can be separated from the garbage by the impact of this collision. Further, since the garbage collides with the stacking rod 56 and is guided to the separation chute 55, even if the speed of the first conveyor 6 is increased, the garbage may not be scattered to the rear side of the second conveyor 7. do not have. Then, the garbage is sequentially collected from the separation chute 55 to the container 8 via the second conveyor 7.

(Effects of the Invention) The present invention is as described above, and a sweeping rotary body is provided in front of the scooping section to sweep dirt and the like that escapes forward from the scooping section into the scooping section and the first conveyor. The garbage being crushed can be reliably scooped up and collected.

In addition, the sweeping rotary body has resilient means on the upper and lower sides of the support stay that supports it, and since it is supported by the resilient means, the sweeping depth can be easily adjusted and it can be easily damaged due to overload. This is advantageous in terms of durability.
