Description

  The present invention relates to a seabed ore excavator used for excavating a seabed, particularly a deposit existing in the deep sea.

  Recently, it has been confirmed by various exploration that there are many seabed deposits with metal resources such as gold, copper, lead, zinc, nickel, cobalt, platinum, other rare metals, rare earths, etc. .

  By the way, in order to use the resources of the seabed deposits, means for crushing and mining the seabed deposits is necessary, and it has been conventionally proposed in, for example, JP-A-7-217361 and JP-A-2004-143741. There are known methods for lowering the scraper from the ship and dropping the claw for rock crushing, but most of them are for use in relatively shallow water and sampling, There are problems in terms of accuracy and crushing effect when applied to deep seas exceeding 1000 m.

  Further, a seabed excavator that directly sinks into the seabed and excavates a deposit is disclosed in Japanese Patent Application Laid-Open No. 63-13029. The seabed excavator presented in this publication has a rectangular plane. A body frame similar to a body frame with telescopic legs at the four corners of the body is supported by a slider so that it can move in a direction perpendicular to the longitudinal direction, and a load head at the front of the body frame and a drum cutter below. Yes, the ore excavated by the drum cutter is sucked by the suction pipe arranged in front of the main body frame and discharged to the rear of the main body frame. The ore discharged to the rear is collected by another accumulator. Is.

  Therefore, in order to excavate seabed deposits and collect the debris on board, it is necessary to load both heavy excavator and stacker on the ship and head to the excavation site, and a large work boat with a wide deck is required. In addition, there is a problem that it is disadvantageous in terms of economy because it requires a lot of equipment costs and operation costs.

  The present invention is intended to solve the above-described problems, and loads an excavator without requiring a large work boat having a wide deck on which both a conventional excavator and a recovery machine are loaded. It is intended to provide a submarine ore excavator that enables excavation and accumulation work with as many ships as possible.

The seabed ore excavator according to the present invention, which has been made to solve the above-mentioned problems, has a drilling device that excavates the seabed deposit in front of the main body frame provided with a pair of left and right crawlers. An excavator provided on the main body frame is removable, and the excavated boom is scattered of the excavated submarine minerals scattered on the sea floor. An accumulation device can be attached to feed the ore into the accumulation tank which is installed in the main body frame and is removable in the vertical direction .

  According to the present invention, by removing the drilling device of the seabed ore excavator and attaching the accumulating device, it is possible to collect and collect the ore that has been taken out by the drilling and drilling operation of the seabed deposit by one seabed ore excavator. By doing so, you can work with less equipment. Moreover, since a large work ship is not required, it is economically advantageous.

In the present invention, when the position sensor that can be detected in seawater is arranged in the recess formed in the main body frame , the recovery tank is surely and quickly returned to the recess. Can do.

  According to the present invention, it is possible not only to run and excavate in a stable state even on the seabed which is unevenness or sloping ground in the deep sea, but also a component of a submarine ore excavator that uses excavated ore for excavation. It is very advantageous in terms of economy including the work boat to be used because it can be collected and recovered simply by changing the slab.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

  The drawing shows a side view of a preferred embodiment of the present invention. As shown in FIG. 1 (a), the seabed ore excavator 1 shown in FIG. The crawlers 3 and 3 are not different from those used on land, for example, by driving means (not shown) mounted on a main body frame such as a motor or a speed reducer disposed on the rear driving wheel 31. In this embodiment, the vehicle is driven by, for example, a wired connection.

  In addition, a slide boom 4 slidable in the front-rear direction is disposed on the main body frame 2, and a fixed boom 5 having a telescopic cylinder 51 and a fixing portion 52 at the front of the slide boom 4 can swing in the vertical and horizontal directions. Is arranged.

  The excavator 6 shown in FIG. 1B or the collapsible accumulator 7 shown in FIG. 1C can be fixed to the fixed boom 5.

  In the present embodiment, the excavator 6 has a built-in drive source, and the excavating drum 61 rotated by the drive source with a plurality of cutting portions projecting from the tip is attached to the fixed boom 5 at the descending end. A fixing portion 62 for fixing is formed.

The ore accumulation device 7 is a frame-like body 73 having an intake port 71 having a lower opening at the front end and a fixing portion 72 for fixing to the fixed boom 5 at the rear end. A loading member 74 is disposed on the outer peripheral surface of the endless belt.

  Then, the submarine ore excavator 1 according to the present embodiment is loaded onto a work ship (not shown) and carried to a work site, and either the excavation apparatus 6 or the accumulation apparatus 7 is fixed on the ship. In the mounted state, for example, it is suspended by a wire or the like and lowered to the sea floor to perform the work, and when performing a different work, the excavator 6 or the stacking device 7 is replaced by being lifted on the ship and fixed, and then mounted. Again, the work is repeated on the seabed.

  In the present embodiment, the excavator 6 or the accumulator 7 attached to the fixed boom 5 is replaced as described above, so that the submarine deposit excavator 1 excavates the excavation and excavation work of the submarine deposit. Can be collected and recovered.
