Many creatures coexist in outer shells such as abalone and shellfish that are generally taken from the sea.

That is, the shell of the shellfish is attached to various species such as aquatic plants and barnacles, and when the divers or daughters collect the abalones or shellfish, the creatures attached to the shells are also collected .

However, since the creatures living on the shell are merely foreign substances that are not necessary to human beings, they are removed from the ship and come out to the market.

Conventionally, foreign substances attached to shells such as abalone or shellfish have been scratched by a knife or pulled out by hand.

Therefore, it was a troublesome and inconvenient thing because we had to hand-hold many shellfish by hand and remove the foreign matter by a manual method, and it was difficult to remove the foreign substances by the hydraulic elimination work, and the foreign matter always remained In addition, there has been a problem that the productivity of the shellfish is lowered and the production amount can not be adjusted due to the above-mentioned conventional foreign matter removal work, Which is not removed by the weight of shellfish, is sold to consumers because it is added to the weight of shellfish.

The apparatus for removing foreign bodies according to an embodiment of the present invention includes a pneumatic chopper 10, a connecting socket 20, a moving shaft 30, a chisel 40, an anti-loose nut 50 ).

The pneumatic chopper 10 is coupled to the connection socket 20 and is configured to reciprocate in the forward and backward directions of the moving shaft 30 coupled with the chisel 40 in the connection socket 20 And a piston 16 that receives the pressure of the high-pressure air and reciprocates in the front-rear direction inside the body 11.

The air chiPer 10 includes a body 11, a hose 12, a switch valve 13, an operation lever 14, , A cylinder (15), and a piston (16).

The hose 12 for supplying high-pressure air is connected to the rear end of the body 11, and the connection socket 20 is screwed to the front end of the hose 12 . In an embodiment of the present invention, the body 11 is formed in a cylindrical shape so as to be easily grasped by a worker, and the cylinder 15 and the piston 16 are contained therein, (Not shown) is formed.

3, a female thread 111 may be formed on the inner peripheral surface of the front end of the body 11 to be screwed with the connection socket 20, And a socket cover 112 covering the outer surface of the connection socket 20 and covering the front surface of the connection socket 20 may be formed.

The hose 12 is connected to the rear end of the body 11 for supplying high pressure air to the inside of the body 11. The high pressure air is supplied to an air compressor (not shown) , And a high-pressure tank (not shown) in which air is compressed.

The switch valve 13 is partially protruded to the outside of the body 11 and opens or closes the inside of the body 11 so that the high pressure air can be supplied or cut into the inside of the body 11 .

The operation lever 14 is configured to pivot the switch 11 on the body 11 by applying pressure to the inside of the body 11 by pressing the switch valve 13 by an operator's operation.

The cylinder 15 is provided inside the body 11 and is hollow so that the piston 16 can be embedded therein.

The piston 16 is built in the cylinder 15 and receives the pressure of the high pressure air supplied into the body 11 through the hose 12 to reciprocate in the forward and backward directions .

The air chiper 10 according to an embodiment of the present invention is constructed in the same manner as the conventional air chiper, which is well known in the prior art, and since the operation principle and the operation method are the same, The detailed description thereof will be omitted.

The connecting socket 20 is coupled to the body 11 of the air chucker 10 and is configured to support the moving shaft 30 to be described later so as to be reciprocated in a forward and backward direction, A moving shaft 30 is screwed to the front end of the body 11 so as to be positioned in front of the piston 16 and has a through hole 21, a pin fixing hole 22, and a fixing pin 23 .

On the other hand, on the outer peripheral surface of the rear end portion of the connection socket 20, a male thread 24 is formed to be screwed with the female thread 111 formed at the front end of the body 11 of the air chucker 10.

The through-hole 21 is formed to penetrate the connection socket 20 in the front-rear direction so that the movement shaft 30 can be inserted and reciprocated in the forward and backward directions.

4, the front side inlet portion 21a of the through-hole 21 is formed in a circular shape and the rear-side outlet portion 21b of the through-hole 21 is formed in a circular shape And is formed in a rectangular shape having a diameter smaller than that of the front side inlet portion 21a of the through-hole 21. At this time, the rear end 31 of the moving shaft 30, which will be described later, is formed into a square pillar shape as shown in FIG. 2 so as to be inserted into the rear side outlet portion 21b of the through hole 21. [

Since the front side inlet 21a of the through hole 21 is formed in a circular shape as described above, it is easy to insert the moving shaft 30 into the through hole 21 and the rear side of the through hole 21 Since the side outlet portion 21b is formed to have a smaller diameter than the front side inlet portion 21a of the through hole 21, the moving shaft 30 can be inserted into the front side inlet portion 21a of the through hole 21, So that it does not escape to the rear-side outlet 21b of the through-hole 21 in a state of being inserted through the through-hole 21b.

In addition, since the rear outlet 21b of the through-hole 21 is formed in a rectangular shape, the moving shaft 30 is inserted into the through-hole 21 to form the rectangular moving post 30, It is possible to reciprocate the moving shaft 30 in the forward and backward directions due to its structural feature in a state where the rear end portion 31 of the through hole 21 is fitted to the rear side outlet portion 21b of the through hole 21, (30) is prevented from rotating in the axial direction.

The pin fixing hole 22 is formed on the side surface of the connection socket 20 in a direction perpendicular to the through hole 21 and is formed at the center of the connection socket 20 in the longitudinal direction of the side surface.

The fixing pin 23 is inserted and fixed in the pin fixing hole 22 and penetrates through a long hole 32 to be described later formed in the moving shaft 30 inserted into the through hole 21 .

When the connection socket 20 and the body 11 are engaged with each other while the fixing pin 23 is inserted into the pin fixing hole 22, So that the fixing pin 23 can be prevented from coming off.

The moving shaft 30 is inserted and supported in the through-hole 21 of the connecting socket 20 so as to reciprocate in the forward and backward directions by the pressure of the reciprocating piston 16.

Preferably, the movement shaft 30 is positioned in front of the piston 16, and the front end of the piston 16 is disposed to be in contact with or close to the rear end of the movement shaft 30.

The rear end portion 31 of the moving shaft 30 is inserted into a rear side outlet portion 21b of the through hole 21 formed in a rectangular shape, As shown in FIG. When the rear end portion 31 of the moving shaft 30 is inserted into the rear-side outlet portion 21b of the through-hole 21 by the structural feature of the moving shaft 30 as described above, The axial rotation of the movable shaft 30 is prevented.

As described above, since the axial movement of the moving shaft 30 is prevented, the chisel 40, which is coupled to the front of the moving shaft 30, is also prevented from rotating in the axial direction, So that the foreign matter removing operation of the shell can proceed more quickly and easily.

The moving shaft 30 includes an elongated hole 32 into which the fixing pin 23 is inserted and a male screw portion 33 formed to engage with the chisel 40.

The elongated hole 32 is formed to have a predetermined length in the forward and backward directions on the side surface of the moving shaft 30 such that the fixing pin 23 is inserted therethrough and the reciprocating distance of the moving shaft 30 is limited. In this case, the length of the elongated hole 32 may be 10 mm to 15 mm, and the length w1 of the elongated hole 32 may be approximately 12 mm.

When the movable shaft 30 reciprocates by the pressure of the piston 16 because the elongated hole 32 having a predetermined length is formed on the movable shaft 30 as described above, So that the reciprocating motion of the moving shaft 30 in the forward and backward directions is limited and the reciprocating movement distance of the moving shaft 30 within the range of the long hole 32 is limited. The chisel 40 also reciprocates in the forward and backward directions and can remove foreign matter such as a barnacle attached to the shell. In this case, the length of the elongated hole 32 may be about 10 mm to 15 mm as described above in consideration of the range of vibration in which the reciprocating movement of the chisel 40 is transmitted to the shell to remove foreign matter.

That is, when the moving shaft 30 is inserted into the through hole 21 of the connection socket 20, the fixing pin 23 is inserted into the pin fixing hole 22 of the connection socket 20, When the moving shaft 30 reciprocates in the forward and backward directions, the fixing pin 23 serves as a stopper in the elongated hole 32, The reciprocating distance of the moving shaft 30 is limited by the length of the long hole 32.

The male threaded portion 33 is formed to detachably couple the moving shaft 30 to the chisel 40 and is formed along the outer periphery of the front end of the moving shaft 30. [ That is, the male threaded portion 33 and the first female threaded portion 411 of the chisel 40 described later are screwed together to detachably couple the moving shaft 30 and the chisel 40. As described above, due to the structural features of the male screw portion 33 of the moving shaft 30 and the first female screw portion 411 of the chisel 40, it is very easy to replace the chisel 40 when the chisel 40 is damaged, (40) can be separated and conveniently stored and carried.

The chisel 40 is coupled to the front of the moving shaft 30 and is reciprocated in the forward and backward directions by the reciprocating movement of the moving shaft 30 to remove foreign matter of the shell.

The chisel 40 includes an engaging portion 41 detachably coupled to the moving shaft 30 and a guiding portion 42 for removing foreign substances from the shell.

One end of the engaging portion 41 is formed to have a predetermined length and is inserted into the moving shaft 30 in a detachable manner so that one end of the engaging portion 41 is inserted into the inner periphery of the engaging portion 41 to be engaged with the male screw portion 33 of the moving shaft 30 The first female screw portion 411 is formed.

A horizontal edge 421 is formed at the other end of the chisel 40, that is, at the tip of the chisel 42.

The guiding portion 42 is formed to extend from the other side of the coupling portion 41 and is formed in a triangular shape having a narrow cross-section after forwarding, and is formed to be bent at a predetermined angle from the coupling portion 41. This is to ensure that when the foreign object of the shell is removed, the hand of the operator is directed to the diagonal direction of the foreign object to be removed and the force transmitted from the hand of the worker is properly applied.

If the lead portion 42 is formed in a straight line without being bent at a certain angle, the body 11 of the air chiper 10 should be vertically erected so that the lead portion 42 of the chisel 40 contacts the shell The chisel 40 does not exert an appropriate force on the foreign substance of the shell, so that it is difficult to scrape the shell by vibrating the chisel 40 in the forward and backward directions.

At this time, the inclined angle alpha of the bending portion 42 may be bent at an angle of 30 ° to 40 ° from the engaging portion 41.

The chisel 40 may further include an inclined blade 422 formed at an angle to the horizontal edge 421 of the saw blade 42 in an oblique direction.

The beveled edge 422 is preferably formed in a V-shape or a U-shape at the central portion of the horizontal edge 421 of the lead portion 42.

2, the inclined blade 422 is formed in a V-shaped depressed groove shape at a center portion of the horizontal blade 421. In this embodiment,

Although not shown in the drawing, it is also possible that the beveled edge 422 is formed in an inclined shape at both side edges of the horizontal edge 421.

5, the slanted blade 422 is formed on the sidewall 42 of the chisel 40 so that the edge of the streamlined foreign material and the slanted edge 422 are removed when the foreign object such as a can opener is removed. The beveled edge 422 is struck in such a manner as to partially cover the marginal portion of the foreign matter, so that the foreign matter such as the barnacle can be easily separated from the shell.

The horizontal edge 421 of the chisel 40 may have a width of 20 mm to 25 mm. If the width of the horizontal blade 421 is too long, the sharp edges of the horizontal blade 421 can injure the hands of the operator holding the shellfish. Therefore, in the embodiment of the present invention, And the width w2 of the blade 421 is formed to be approximately 22 mm.

The inclined blade 422 of the chisel 40 may have a width of 3 mm to 5 mm and a depth of 3 mm to 5 mm.

In the embodiment of the present invention, the beveled edge 422 is formed to have a width w3 of about 3 mm and a depth d of 3 mm within the range of width and depth as described above.

The size of the foreign object such as the snare barrel and the snare attached to the shell of shellfish such as rolled up is usually less than 1 cm. The small foreign object is peeled through the beveled edge 422, The method of pushing out through the blade 421 can be performed in parallel, so that the foreign matter removing operation of the shell can be easily and easily performed.

The release preventing nut 50 is structured such that the chisel 40 can be firmly coupled to the moving shaft 30 and is formed with a hollow second female threaded portion 51, And is screwed to the male screw portion 33.

The unlocking nut 50 rotates along the moving shaft 30 while the moving shaft 30 and the chisel 40 are screwed together and presses and supports one end of the chisel 40 Thereby preventing the chisel 40 from being loosened.

The above-described shell foreign matter removing apparatus shown in the drawings is only one embodiment for carrying out the present invention, and should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is defined only by the matters set forth in the following claims, and the embodiments improved and changed without departing from the gist of the present invention are obvious to those having ordinary skill in the art to which the present invention belongs It will be understood that the invention is not limited thereto.
