Description

[Detailed description of the invention] This invention is attached to the tip of the blade of a crawler-type bulldozer, for example, and allows coal, etc. thrown into the hold of a ship to accumulate at the approximate center of the ship without damaging the bottom of the ship. This relates to auxiliary blades.

For example, the cargo hold of a bulk carrier, etc., is fully loaded with coal, etc., which must be unloaded at a predetermined location in the shortest possible time using the grab bucket of an unloader. Since it is not possible to carry out items near the bottom of the cargo hold or scattered in the corners of the cargo hold in that state, a crawler bulldozer or the like is brought into the cargo hold and the tip of the bulldozer is removed. A blade attached to the vessel is used to collect coal, etc. on the bottom of the ship in advance at a substantially central position,
The cargo was unloaded overboard using the aforementioned grab bucket.

However, with this type of conventional crawler bulldozer, etc., it is not possible to run parallel to the bottom of the ship at all times over the coal seam remaining on the bottom of the ship. The disadvantage is that the coal cannot be collected in the center of the ship, and the approximately 3 to 5 cm thick coal seam that remains on the bottom of the ship must be manually removed, and the bottom of the ship is damaged during this process. This had problems such as causing

The present invention was created in view of the above problems, and is attached to the lower part of the blade of a bulldozer carried into the ship's hold to completely remove coal, etc. remaining in the ship's hold without damaging the bottom of the ship. To provide an auxiliary blade that can scrape together and collect cargo, is easily fitted and removed, and is flexible.

Hereinafter, the auxiliary blade of the present invention will be described in detail based on an embodiment shown in the drawings.

In the figure, reference numeral 3 indicates an auxiliary blade of the present invention that is attached to a blade 2 attached to the front of a crawler bulldozer 1, for example, and the auxiliary blade 5 is flexible and It is constructed so that it can be easily attached to and removed from the lower part of the device.

That is, the auxiliary blade 5 of the present invention is made of synthetic resin or the like having the required flexibility, and has a lower end extending forward and an upper surface having a curved shape so as to extend the protrusion 3 at the tip of the blade 2. ,
The upper end portion is provided with a fitting groove 6 into which the bottom portion 4 of the blade 2 can be inserted so as to be able to be attached to the end of the blade 2, and a predetermined interval is provided in each width direction at a predetermined position in the upper portion of the curved portion. A plurality of bolt through holes 7 are provided perpendicularly to the insertion direction of the blade 2.
It is equipped with the following.

Incidentally, the entrance portion of each of the through holes 7 is provided with a bolt head fixing groove 8 having a hexagonal shape, for example, which is recessed to prevent rotation of the bolt 9 inserted therein.

Further, 10 is a T-shaped nut for fixing the bolt 9.

The auxiliary blade of the present invention is constructed as described above, and when it is to be attached to the blade of a bulldozer, it must be installed in advance on the bulldozer 1.
A plurality of auxiliary blade fixing holes are provided in the lower end portion 4 of the blade 2 in the width direction of the auxiliary blade 5, each of which communicates with each bolt through hole 7 provided at a predetermined position in the upper part of the auxiliary blade 5. After inserting the lower end 4 of the blade into the insertion groove 6 of 5 and inserting the bolt 9 into the bolt through hole 7 and the auxiliary blade fixing hole communicating with this, tighten it with the fixing T-shaped nut 10. By fixing the auxiliary blade 5 to the blade 2, it is easy to attach the auxiliary blade 5 to the blade 2, and when removing it, simply loosen each fixing T-shaped nut 10 and pull out each bolt 9. The blade 5 can be easily removed from the blade 2.

Therefore, since the auxiliary blade of the present invention is configured to be able to be fitted and removed as described above, it can be easily attached to the tip of the blade of a bulldozer, and is flexible. By attaching it to the blade of the bulldozer and using it, it is possible to scrape up the coal, etc. remaining in the hold of the ship as completely as possible without damaging the bottom of the ship, and to collect it at an appropriate location. This is an advantageous feature in that the cargo in the hold can be unloaded in the shortest possible time and easily using the grab bucket of the unloader.

In the above embodiment, the auxiliary blade of the present invention is used as a bulldozer blade, but the invention is not limited to this, and it goes without saying that the auxiliary blade of the present invention may also be used on a bucket cart or the like.
