[0002]

[Prior art]

 Conventionally, for example, in Japanese Utility Model Laid-Open No. 56-20605, a traveling carriage that straddles the sand basin and travels along the sand basin is provided in the upper part of the sand basin, and the traveling trolleys are vertically arranged on both sides. Each rocking arm that rocks in the direction is provided so that when the lower end of the rocking arm reaches the bottom of the sand basin when it descends, and when it rises, it is above the sand basin. A bucket conveyor is constructed by installing a plurality of buckets between a pair of front and rear endless chains that are wound around a conveyor frame.

When the sand is picked up, the swing arm is turned downward to run the endless chain and the bucket is used to scrape the sand. When the traveling carriage is moved, the swing arm is turned upward. The endless arms between the lower ends of the endless arms are prevented from hitting the upper part of the sediment basin.

[0004]

[Problems to be solved by the device]

 In the prior art as described above, when the rocking arm is directed right below, the endless chain between the lower ends of the rocking arm becomes tense and the buckets can be scraped off by the buckets. When positioned, the lower ends of both swinging arms approach each other, so scraping work can only be done at the bottom. Therefore, there is a problem that the upper surface of the settled sand cannot be scraped when the settled sand is thick.

An object of the present invention is to solve the above-mentioned problems of the conventional device and to provide a sand scouring machine capable of scraping not only the bottom but also the sand at a portion shallower than the bottom. is there.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the means taken by the present invention is to provide a traveling carriage on the upper part of the sand basin that straddles the sand basin and travels along the sand basin. Is equipped with a telescopic arm that expands and contracts in the vertical direction.When the lower end of the telescopic arm reaches the bottom of the sand basin when it descends, and when it ascends, it is above the sand basin. A bucket conveyor is configured by installing a plurality of buckets between a pair of front and rear endless chains that are wound around a plurality of guide wheels provided on the conveyor frames on both ends, and the buckets are provided on the conveyor frame. A take-up mechanism for removing the slack of the conveyor is provided so that the settled sand scraped by the bucket conveyor is fed into a chute provided on the conveyor frame.

[0007]

[Action]

 When scraping the sand at the bottom of the sand basin, extend the telescopic arm to the maximum so that its lower end reaches the bottom of the sand basin and run the endless chain so that each bucket attached to this endless chain Scrape bottom sediment.

In addition, when scraping off the sediment that has settled slightly above the bottom, the telescopic arm is slightly retracted, and the lower end is set higher than the bottom, and the endless chain is run as described above. By doing so, it is possible to scrape off sediment that has settled higher than the bottom.

【Example】

 In the embodiment shown in the figure, 1 is a sand basin, and this sand basin 1 is divided into a plurality of partitions by partitions 2 as shown in FIG. Reference numeral 3 is a traveling carriage that runs on the rail 4 provided along the sand basin 1 and along the sand basin by driving wheels.

Telescopic arms 5 that extend and contract in the vertical direction are provided on both sides of the traveling carriage 3, and when the lower end thereof descends, it reaches the bottom of the sand basin 1, and when it rises, from the upper end of the partition 2 of the sand basin 1. Try to be on top.

The lower end of the telescopic arm 5 is integrally connected by a connecting frame 6, and is further provided between the guide wheel 7 at the lower end of the telescopic arm 5 and the conveyor frame 8 on the traveling carriage 3 as described later. A bucket conveyor 11 is constructed by mounting a plurality of buckets 10 between a pair of front and rear endless chains 9 that are hung around each other so as to hang down around an axis.

One end of a take-up arm 12 is swingably mounted on both sides of the traveling carriage 3, and a tension wheel 13 is rotatably mounted on the free end thereof, and a weight 19 is fixed. Configure a take-up mechanism.

Then, a pair of guide wheels 14 are arranged at upper portions on both sides of the traveling vehicle 3 so as to be located on both sides of the tension wheel 13.

Further, a drive chain 15 and guide wheels 16 and 17 are arranged at a portion of the one conveyor frame 8 located outside the telescopic arm 5, and the other conveyor frame 8 is provided with the telescopic arm 5. A guide foil 19 located outside is provided. Then, as shown in FIG. 1, a plurality of guide wheels 19 and 20 are arranged in a portion of the traveling carriage 3 straddling the sand basin 1.

The endless chain 9 is put on each of the guide wheels 7, 14, 16, 17, 18, 19, 20 and the tension wheel 13 and the driving chain wheel 15, and the guide wheels 16, 17 are covered with a chute 22. Then, the discharge port 23 at the lower end is exposed to the carry-out conveyor 24.

The chain wheel 15 is driven by a drive motor 21 to drive the bucket conveyor 11 in the direction of the arrow in FIG. Further, the telescopic arm 5 is, for example, a first elevating frame 26 which is vertically mounted on a guide frame 25 fixed near both ends of the traveling carriage 3, and a second elevating frame which is vertically mounted on the first elevating frame 26. 27, the first and second elevating frames 26, 27 are moved up and down by a rack and pinion mechanism or an elevating mechanism using a chain, whereby the retractable arm 5 is freely expanded and contracted.

Now, when the two telescopic arms 5 are maximally extended, the chain 9 between the guide wheels 7 at the lower ends of the two telescopic arms 5 is closest to the bottom of the sand basin 1, so in this state When the chain 9 is driven, each bucket 10 travels in the direction of the arrow in FIG. 1 while scraping the sediment deposited on the bottom of the sand basin 1.

Then, between the guide wheels 7 and 19 on the right side of FIG. 1, the guide wheels 14 and tension wheels 13 of the take-up mechanism ascend between the guide wheels 7 and 19 to the left along the lower guide wheels 19 and 20. The guide wheel 14 and the tension wheel 13 of the take-up mechanism on the left side bends to a U shape, guides downward from the upper guide wheels 14 and 17, and is inverted at the wheel 16 and is driven by the drive wheel 15. Is guided to the lower guide wheel 7.

In the above operation, each bucket 10 is laid sideways at the bottom soil scraping portion to scrape the sand, but ascends and descends at the descending portion with the mounting axis of the bucket 9 as a fulcrum. Do not spill the contents because it does. Then, in the shoot 22 of FIG. 1, an action piece provided inside acts on a part of the bucket 10 to invert the bucket 10, thereby discharging the earth and sand of the content from the discharge port 23. It is discharged to the lower carry-out conveyor 24.

In addition, when there is a large amount of sediment in the sand basin 1, the telescopic arm 5 is contracted to raise the guide wheel 7 at the lower end so that each bucket 10 is at a position to scrape the surface of the sediment, and the chain 9 is run. By doing so, the surface of the earth and sand can be scraped off.

When the scraping of the surface is completed, the telescopic arm 5 is slightly extended to lower the chain 9 and scraping is started again. By repeating this process, thick sediment can be easily removed. In the above action, the take-up arm 12 moves up and down according to the change in the slack of the chain 9 due to the expansion and contraction of the expandable arm 5, and the length of the U-shaped portion of the chain 9 is changed, so that the chain 9 is always loosened. I try not to.

[0022]

[Effect of device]

 In this invention, the endless chain is stretched on the guide wheel provided at the lower end of the vertically extending telescopic arm as described above, and the bucket attached to the end is used to scrape the sand. Since the distance of the guide wheel at the lower end does not change, it can be scraped by the bucket conveyor at any height. Therefore, even if the thickness of the sediment is large, the sediment can be easily scraped off. When the telescopic arm is contracted to the maximum, the bucket conveyor does not get in the way, so the traveling vehicle can easily move on the sand basin. Furthermore, since the telescopic arm expands and contracts vertically, the telescopic arm does not vibrate during expansion and contraction.
