度選別装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a suction head installed at the tip of an ore collecting duct close to the seabed by a water flow generated by a pump or the like inside the ore collecting duct while moving on the seabed. In an ore collecting device that sucks in nodules such as manganese nodules existing on the bottom surface of the tumor through the suction port and collects the ore, nodules that fall within the particle size range of the nodules to be collected are separated from nodules that have a particle size that exceeds that range. This invention relates to a particle size sorting device.

に揚鉱することが必要である。The case of manganese nodules will be explained below, but the present invention can also be applied to a particle size sorting device for an ore collector for seabed mineral resources similar to manganese nodules. Manganese nodules, which are attracting attention as a resource, are found on deep seabed sediments on a flat surface, similar to cobblestones. Therefore, in order to collect this, it is necessary to collect the nodules distributed on the seabed and lift the ore to the Tomogami Sea.

ている。As a manganese nodule collecting device, the so-called fluid dredge method mentioned above is superior because it has a simple mechanism and fewer failures.

面下に没したもの等積々の状態で賦存している。Seabed sediments containing manganese nodules are generally soft and muddy, and manganese nodules range from being entirely exposed on the seafloor sediment, like a ball rolling on the ground, to being about half exposed on the seabed surface. Some of them have sunk beneath the ocean floor like icebergs, and many of them still exist in piles.

対象範囲外としてサクションヘッドに入らないように選
別して排除することが必要である。In addition, the size of manganese nodules varies, but due to economic considerations such as the diameter of the ore lifting pipe and the required power for lifting ore, those with a large diameter of 80 to 100 square meters or more, which have a small endowment rate, are It is necessary to sort and eliminate the ore so that it does not enter the suction head as it is outside the scope of ore collection.

ある。Regarding this sorting device, a conventional method has been proposed in which a sorting grid is provided in front of the suction head, extending vertically in a direction diagonal to the direction of travel, extending above and below the seabed surface, and using this to push out nodules to be excluded outward. However, in order to smoothly push out large-diameter nodules, it is necessary to make the angle of the sorting grid with respect to the direction of progress of the ore collection charge at a fairly acute angle, and if the width of the suction head increases, the size of the sorting device becomes very large.

較べてはるかに小規模のものとすることが可能である。Therefore, the inventor of the present invention first opened the suction port of the suction head diagonally downward in the direction of travel, and established a position between a position at an appropriate height above the seabed in front of the suction head and a position directly below the trailing edge of the suction head. In between, there is a particle size sorting device consisting of a plurality of flat par-shaped crosspieces arranged at intervals corresponding to the particle size to be sorted and parallel to each other in the vertical plane in the longitudinal direction and diagonally to the seabed surface within the range of the opening width of the suction head. Proposed. As a result, nodules within the diameter range of the collected ore grains pass between the bars of the lattice and flow into the suction head, and nodules with a large diameter exceeding this range are blocked by the lattice and are prevented from flowing into the suction head. However, as the ore collector moved forward, it became possible to push the ore into the soft seabed sediments and leave it behind using the inclined lattice bars. Since the depth to which the nodules are pushed is at most several 10 to several tens of liters, the sorting device can be made much smaller than the previously proposed devices.

次に本発明の団塊粒？昼度選別装置について説明する。As described above, seabed sediments are soft and have poor bearing capacity, so the ore collector frame 1 is usually supported on the seabed surface 4 by a plurality of rows of skis 6 via a plurality of suspensions 5. Since there are irregularities on the seabed surface, in order to make the skis 6 follow the irregularities, the skis 6 are made of a flexible steel plate or the like, and the frame It is elastically supported by a suspension 5 having a spring. Therefore, if there are irregularities on the seabed surface 4 in the moving direction of the ore collector, the distance between the front end of the frame l and the seabed surface 4 will change, and there will also be irregularities on the seabed surface within the width of the moving ore collector. As a result, the distance and parallelism of the lower edge of the suction port of each suction head to the seabed surface change, and the ability to collect manganese nodules changes. Therefore, in order to detect the height of the seabed relative to Kelf V-A1 and the parallelism between each suction head and the seabed surface, an arm is attached to the part where the suction head is located, so that it can swing freely around a shaft fixed below the front end of the frame 1. 7
are provided between each suction head 3 and on the sides of both rows, and the free ends thereof are attached to the seabed surface 4t and the rolling rollers 8, and these are detected from the angle formed by each arm 7 and the frame 1. The connection between the suction head 3 and the ore collecting duct 2 is made up of an arcuate surface centered on a shaft 9 fixed to the lower front end of the frame 1 and flat surfaces on both sides, which can fit into each other and slide. The ore collecting duct 2 is fixed to the frame 1, and a part 3c of the suction head 3 is fixed to the other end of an arm 1o whose one end is supported by a shaft 9. Remaining parts 3a, 3btl
The arm 10 is pivotally supported by pins 11 and 12 provided at both ends thereof in the length direction thereof, respectively. Therefore, the lower edge of the opening 3a of the suction head 3 can vary in height and inclination with respect to the frame 1. Therefore, from the angle of each arm 7 with respect to the frame 1, a control section (not shown) detects the height of the seabed at the suction head section and the slope of the seabed surface at the position of each suction head, and the signal is used to control the hydraulic servo mechanism (not shown). Through: An operating device such as a hydraulic cylinder allows the height and inclination of the opening of each suction head to always follow the seabed surface.◇Next, what about the nodules of the present invention? The daytime sorting device will be explained.

The lower surface of that part is opened to the full width and length and serves as a seawater and manganese nodule inlet 3a. The suction ports 3aK are provided over the entire range in parallel to the inclination direction of the crosspieces 21t and the suction ports 2o, and in parallel to each other, to form a sorting grid. ing.

It prevents you from doing so. A piston rod 28 of a hydraulic cylinder 27 is attached to the member 24, which is provided parallel to the inclination direction of the sorting grid, and the gap between the clogging removal member 25 and the sorting grid 22 is shown as a solid line in FIG. 2 over the entire length. It is possible to reciprocate between the position shown by and the position shown by the chain line.

。Since this device is constructed as described above, when a water flow is generated in the ore collection duct 2 by a pump or the like during operation, seawater is sucked in from the suction port 3a, and as a result, the manganese nodules deposited on the seabed are lattice-capped. Nodules with a particle size smaller than the gap are sucked into the suction head 3. Nodules having a particle size larger than the gaps between the grids are blocked by the grids, and are pushed into the seabed sediment by the grids 22 as the ore collector advances and are left behind.

める。Nodules that are exactly equal to or slightly larger than the spacing between the grids 22 may be pushed between the crosspieces 21 of the grid 22 by the water flow and become clogged. When the teeth 27 of the clogging removal member are made to move reciprocatingly at a constant period by expanding and contracting, the front and rear surfaces of the teeth 23 of the clogging removing member face diagonally downward between the crosspieces 21 of the lattice, so the reciprocating movement removes the lumps stuck in the gaps between the lattice. By pushing, a downward component of force is generated, causing the baby boom to fall downward.

鉱作用は連続的に行なわれる。Since the area of the gap in the grid that is blocked by the clogging removal member is small, the reduction in ore collection efficiency due to the installation of this member can be ignored, and the clogging removal device is operated. Since the water flow is not interrupted during this time, ore collection is carried out continuously.
