2. Description of the Related Art Conventionally, shellfish has been collected by manually scooping earth and sand at the bottom of the water using a spade basket or a rake, and selecting shellfish from the earth and sand. The work of collecting shellfish was hard work to bend down, and the efficiency of collection was poor because it was manual work.

In order to solve the above-mentioned problems, an automatic shell-fishing apparatus as described in Japanese Utility Model Registration No. 3021940 has been developed. FIG. 6 shows a side view of this automatic shell collecting apparatus. In the automatic shell collecting apparatus 9, a straight plate-shaped excavating plate 91 which is provided to be inclined downward in front of a traveling device 90 having a crawler portion 94 excavates and digs up the water bottom by running, and digs up the soil containing shellfish. A sorter 93 (hereinafter referred to as a “vertical wire” in the above specification) in which the earth and sand including shells placed on the excavation board 91 is formed in a cage shape by a chain conveyor 92. However, in the present specification, as described above, the shellfish is collected while being transported while passing over.

[0004] The automatic shell collecting apparatus 9 is capable of automatically collecting earth and sand including shells from the water bottom by running the traveling device 90. In addition, earth and sand including shellfish
Since it is conveyed while passing over the sorter 93, unnecessary earth and sand can be dropped from the gap of the sorter 93, and thereby shellfish can be roughly sorted from the earth and sand. As described above, according to the automatic shell collecting apparatus 9, it is possible to easily and efficiently collect shellfish which has conventionally been regarded as heavy labor.

[0005]

However, the above-mentioned automatic shellfish collecting apparatus has the following problems. Since the excavation plate 91 is in the shape of a straight plate, when the water bottom is excavated by the excavation plate 91, almost all of the excavated shell and sand including the shells is continuously moved along with the operation of the automatic shell collecting device 9, and the excavation plate 91 is continuously excavated.
Move to get on top. That is, the excavated earth and sand moves as described above, so that the earth and sand that is firstly placed on the excavation plate 91 is subjected to a pressing force that is to be pushed up by the earth and sand that is going to be put on later, Further, since a pressing force due to the movement of the wing plate 920 provided on the chain conveyor 92 is also applied, the shells contained in the earth and sand may be broken by these.

When the blade 920 moves from the upper side to the lower side in order to convey the earth and sand loaded on the excavation board 91, the earth and sand are separated between the tip end of the blade 920 and the sorter 93. In some cases, the contained shellfish was pinched and crushed.

Further, as described above, the sediment loaded on the sorter 93 is almost the entire amount of excavated sediment, so that the amount of the sediment conveyed by the blade plate 920 is large, and the chain conveyor 92 and the prime mover for driving the same are driven. And so on.

(Operation) The operation of the embodiment of the present invention will be described with reference to the drawings. First, the sampling device 2 is inclined downward, and the height of the roller 24 is adjusted by the elevating device 230 to set the depth of the earth and sand that the excavating member 22 excavates. Then, the collecting machine S is driven to excavate earth and sand including shellfish. At this time, the excavated earth and sand has a feeling of rising upward along the curvature of the excavating member 22 and inverting. As a result, the excavated earth and sand will not be continuously loaded on the carrier 215 with almost the entire amount.

In the sampling machine S, the earth and sand excavated by the excavation member 22 is given a fluidity by the water pressure of the water jetted from the jetting member 26 so as to be easily transported, and is pushed to the earth and sand inlet 25. Then, the sheet is sent onto the transfer table 215 by the transfer plate 211 and is transferred.

Due to the above-mentioned action, the sediment containing shellfish is
It is not conveyed in a continuous state, but is conveyed in a substantially intermittent state. Therefore, unlike the conventional sampling machine, the shellfish is not broken by the pressing force due to the earth and sand that is going to be put on later and the pressing force due to the movement of the carrier.

Also, by imparting fluidity to the earth and sand including shellfish, the compacted earth and sand usually becomes soft and easy to flow.
The amount of the earth and sand conveyed by can be reduced. Therefore, it is possible to reduce the load on the transfer device 21 and the prime mover 5 that drives the transfer device 21.

Are transported by the endless chains 210, 210 to the sediment inlet 25 of the transport device 21.
When the transport brush 212 tries to contact the transport table 215 and sandwiches shells in the earth and sand,
Since the pressure of water by the jetting member 26 is applied to the sandwiched shellfish, the shellfish is blown off in the transport direction before being crushed and sent to the transport table 215. Therefore, the shellfish are not crushed.

The endless chains 210, 210 are driven by the endless chains 210, 210, and the transport plates 211,... Attached thereto move the transport plates 211,. It is conveyed on the conveyance base 215 so that it may be pushed (refer FIG. 5).

Since the transfer table 215 is formed in the shape of a slab, unnecessary sand and the like that can pass through the gap of the transfer table 215 among the earth and sand are conveyed by the transfer plates 211,. Can be dropped. In other words, the shellfish can be roughly sorted out of the soil at the same time as the soil containing the shellfish is transported on the carrier 215.

The shells and the like transported on the transport table 215 are:
Next, it is taken into the inlet 30 of the sorting hopper 3. The sorting hopper 3 is oscillating, and acts like a so-called sieve. That is, the shellfish and the like taken into the input port 30 of the sorting hopper 3 are separated on the sorting table 32 into shellfish and the like to be collected and pebbles and shellfish and the like smaller than the size to be collected.

The shellfish to be collected which has not fallen on the sorting table 32 is gradually moved to the rear side by the tilting of the sorting table 32 and the swinging of the sorting hopper 3, and the collecting port. It enters the collection basket 8 from 33 and is collected. In addition, sorting table 3
Pebbles falling into the inside of the sorting hopper 3 from the gap 2 and shellfish smaller than the size to be collected are discharged from the outlet 31 to the through hole 1.
It is returned to the bottom through 10.

Since the washing device 4 is provided above the inlet 30 of the sorting hopper 3, water can be sprayed on the shells taken on the sorting table 32 to wash the shells. As a result, the cleaning work that has been performed after being collected in the collection basket 8 can be eliminated, and labor can be reduced. Also,
Since the cleaning device 4 sprays with a considerable water pressure, the sorting operation on the sorting table 32 is also facilitated.

Crawler sections 10 and 10a of traveling device 1
But at different heights where they touch each other on the ground
When the crawler unit 10 is provided , and when the one crawler unit 10 travels on a portion that has been dug up and lowered by the dug up member 22, the dug up member 22 is set to be parallel or substantially parallel to the surface of the water bottom. So that you can drill below the layer of shellfish. This makes it possible to prevent the shell layer from being cut diagonally, and to prevent the tip of the digging and raising member 22 from hitting the shell and damaging the shell or breaking by the pressing force caused by traveling. .
