Description

  The present invention relates to a shaving tool, and more particularly to a shaving tool suitable for shaving barnacles attached to a shell of an irregularly shaped rock oyster.

  In recent years, rock oyster culture technology has been established, and rock oysters are cultivated in various places, including the Oki Islands in Shimane Prefecture. Aquaculture is mainly underwater suspension system. When shipping, several rock oysters stuck to the rope are broken apart and separated individually, and further, calcium-based surface deposits such as barnacles and snake shells. Scrape off.

  Conventionally, this cutting work has been performed using an impact driver or the like.

  However, since the impact driver has a single hit point, the oyster shell is easily damaged, and there is a problem that the impact driver is not necessarily suitable for scraping the surface deposit of the rock oyster having a relatively large area.

  On the other hand, a needle chisel type shaving tool for forming a design on an outdoor wall of a house or removing rust from a metal is also known. This is a device that vibrates a plurality of elongated chisel sticks (needle chiseles) that are close to each other while being separated from each other by a short stroke, and scrapes the tip contact portion into a relatively large area (Patent Document 1). ~ 5).

  However, if the target is an irregular shape that rises like the shell of a rock oyster, all needles will not be hit with a short stroke, and the large area shaving process will be impaired. There was a problem.

<Shaving device>
FIG. 1 shows a shaving tool (hanger) according to the present invention, that is, a shaving that uses a plurality of slender needle chisel units containing a plurality of wire-like needle chicks of a predetermined thickness. It is explanatory drawing which showed the structural example of the tool. In the figure, it is drawn as a perspective view of a posture in which the needle chisel is directed upward. Also, the needle chisel draws only one needle chisel unit. FIG. 2 is a bottom view of the needle chisel unit. However, the drawing of the needle chisel is omitted. FIG. 3 is a cross-sectional view showing a configuration outline of the needle chisel unit. FIG. 4 is a conceptual diagram showing a state in which each needle chisel unit follows the surface of the object to be cut to create a height difference. In FIG. 3 and FIG. 4, drawing of an air supply hose and the like is omitted.

  The sharpening tool 1 mainly includes seven needle chisel units 10 and a unit holder 20 through which the needle chisel units 10 are inserted, and each needle chisel unit as shown in FIG. By adopting a configuration in which 10 is freely moved back and forth in the axial direction (sliding), the surface unevenness of the object to be cut is followed to realize efficient shaving.

  The needle chisel unit 10 includes a needle holder 11, a needle chisel 12, an anvil 13, an air supply unit 14, and a coil spring 15. The needle chisel 12 is made minute by air pressure and spring force. Vibrate or finely vibrate (FIG. 3). Specifically, it is as follows.

  The needle holder 11 is a long bottomed hollow cylinder constituting the casing of the needle chisel unit 10. As shown in FIG. 1 or 2, the outer shape is a regular hexagonal column, and a plurality of needle holes 112 are provided on the bottom surface 111 in the longitudinal direction (axial direction). Needle chisel 12 is inserted through the needle hole 112, and a total of seven needle holes 112 are provided for rotation at 60 ° with respect to the shaft. Because of this positional relationship, the adjacent needle holes 112 are all equidistant. As will be described later, the needle chisel unit 10 abuts the side surfaces of the housing, but the distance between the outer needle holes 112 belonging to each of the needle chisel units 10 is also substantially equal to this distance. In other words, in the shaving tool 1, it can be said that the needle chisel 12 is arranged almost uniformly without depending on the location (FIG. 2).

  The needle chisel 12 is an elongated bar-shaped high-strength metal bar that is inserted through the needle hole 112. Here, a hard steel wire is used as the material. The proximal end 121 is larger than the needle hole 112, and the proximal end 121 side is accommodated in the needle holder 11 so that the needle chisel 12 does not fall out of the needle holder 11. The tip 122, which is the other end of the needle chisel 12, vibrates against the surface of the object to be shaved and presses against the surface to be ground.

  The anvil 13 is housed in the needle holder 11 and vibrates the needle chisel 12 by striking the proximal end 121 of the needle chisel 12 by microvibration in the axial direction. Specifically, it is an integral body having a shaft bar portion 131 and a striking surface portion 132, and the striking surface portion 132 is substantially inscribed in the needle holder 11 and closes the bottom surface 111. The shaft bar portion 131 connected to this has a smaller diameter than the striking surface portion 132, and the coil spring 15 is inserted in this gap formed between the shaft bar portion 131 and the needle holder 11.

  By inserting the coil spring 15 into the reduced diameter portion of the anvil 13, it is possible to avoid the occurrence of a radial bulge that occurs when the coil spring is disposed outside the needle holder 11 or around the needle cup 12. . This makes it possible to smoothly move back and forth (slide) in the axial direction without interfering with each other while bringing the needle chisel units 10 into close contact with each other. In addition, the needle chisel 12 can be arranged even near the periphery of the needle chisel unit 10 and includes the needle chisel 12 of the adjacent needle chisel unit 10 as described above. Thus, the arrangement of the needle chisel 12 can be made substantially uniform.

  An air supply unit 14 is disposed on the base end side of the shaft bar portion 131 of the anvil 13, and the anvil 13 vibrates due to the air pressure of the air supplied from the air supply unit 14 and the spring force of the coil spring 15. That is, the air from the air supply unit 14 tries to separate (float) the striking surface portion 132 from the bottom surface 111, and the coil spring 15 tries to press the striking surface portion 132 toward the bottom surface 111. Although illustration is omitted, the side surface of the needle holder 11 and the hitting surface portion 132 are provided with air escaping holes, so that the micro-vibration continues without both forces being balanced.

  In actual driving, the seven needle glasses 12 vibrate apart by the striking vibration to the base end 121 of the striking surface portion 132 to realize effective cutting.

  As shown, the unit holder 20 accommodates and inserts seven needle chisel units 10, and each needle chisel unit 10 can freely move in the axial direction with respect to each other and the unit holder 20. It is like that. As a result, the needle chisel unit 10 hits the surface of the object to be cut by its own weight, and can change the height of each, and as a whole, it is possible to realize cutting that follows the surface. FIG. 4 illustrates the state of following.

  For actual shaving, the user places the shaving tool 1 on the object to be shaved so that the needle chisel unit 10 does not fall out of the unit holder 20, for example, a rock oyster shell, and starts vibration. The unit holder 20 is appropriately moved so as to draw a circle, and the work is performed so that the needle chisel 12 hits the entire surface to be cut. Each needle chisel unit 10 follows surface irregularities, so that efficient cutting is performed.

  As described above, according to the cutting tool 1 of the present invention, even if the unevenness on the surface of the object to be cut is steep, each needle chisel unit 10 changes the height and follows the unevenness, so that the conventional needle In fact, it cuts a large area and is superior in workability.

In addition, this invention is not limited to said aspect.
For example, a locking portion may be provided on the upper part of the needle chisel unit 10 (upper part of the needle holder 11), and the falling of the needle chisel unit 10 from the unit holder 20 may be restricted.

  Further, the needle chisel unit 10 hits the surface of the object to be cut by its own weight, but depending on the mode of use, for example, the lower side (the tip 122 of the needle chisel 12 is used by utilizing the aerodynamic force of the air supply unit 14. Side).

  Further, a mechanism may be adopted in which the air from the air supply unit 14 pushes the striking surface portion 132 toward the bottom surface 111 and the coil spring 15 pulls back the striking surface portion 132 from the bottom surface 111 to keep the vibration. In addition, a striking part may be provided independently of the air pressure, and this vibration may be transmitted to the anvil 13 to form the vibration. Further, the anvil 13 itself may be a vibrating body.

<Shaving device>
Next, the shaving apparatus will be described. Here, a shaving apparatus for shaving off deposits on the surface of the shell of rock oysters will be described. FIG. 5 is an explanatory view showing an example of the shaving apparatus of the present invention. The shaving device 5 includes a shaving tool 50, an endless belt 60, and a shaving tool adjusting base 70. In addition, about the shaving tool 50 here, about the component similar to the above-mentioned shaving tool 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

The cutting tool 50 includes a needle chisel unit 10 and a unit holder 51.
The unit holder 51 inserts the needle chisel unit 10 into 6 groups × 3 rows = 18 groups (FIG. 5 a). Below that, as shown in FIG. 5b, there is provided a bottom surface 511 having an edge with a predetermined width along the tortoiseshell pattern and punching out the inner side of the pattern (in FIG. 5c, a dotted line). The side of the needle chisel unit 10 is shown). The needle chisel unit 10 is not dropped from the unit holder 51 by the bottom surface 511, and each needle chisel 12 projects downward without being in contact with the bottom surface 511. That is, in the needle chisel unit 10, the needle holder 11 cannot be pulled out by the bottom surface 511, and further lowering is restricted. 5a and 5b show that the needle chisel unit 10 has completely fallen down and the bottom surface 111 of the needle holder 11 is in contact with the bottom surface 511 of the unit holder 51 (needle chisel). The height of the unit 10 is aligned).

  As shown in the figure, the unit holder 51 has a rectangular parallelepiped outer shape, but is held above the endless belt 60 by the cutting tool adjusting base 70 and oriented at a predetermined angle with respect to the transfer direction of the endless belt 60. Can be adjusted. Specifically, the needle chisel unit 10 is oriented at a predetermined angle of 10 ° to 40 ° on the transfer upstream side of the endless belt 60. In FIG. 5b, an embodiment in which the fixing bolt 71 is fixed at an angle of about 25 ° is shown. The inclination angle is set according to the amount of deposits on the shell and the transfer speed. This is because the crust is generally mountain-shaped, and efficient shaving can be realized by orienting it to be transferred.

  In driving, as described above, the sharpening tool 50 is oriented at a predetermined angle and fixed with the fixing bolt 71, and then the air supply unit 14 starts air supply, and then the endless belt 60 is driven. The rock oysters are sequentially placed on the upstream side of the endless belt 60. In addition, illustration of an air supply tube etc. is abbreviate | omitted.

  It should be noted that, due to the orientation, the upper half of the rock oysters are well shaved. Accordingly, the entire upper surface (shell) of the rock oyster is scraped by passing through the shaving device 5 twice. You may make it pass through several times. Depending on the mode of use, another shaving tool 50 may be provided downstream, and the entire surface may be shaved by providing a rotating mechanism for rotating the rock oyster 180 degrees therebetween. Further, it may be reversed and the lid shell may be shaved.

  As described above, the shaving device 5 makes the shaving work a line and enables automatic shaving.

  The present invention is not limited to rock oysters, and is used for efficient cutting using needle chisel on an object whose surface irregularities are irregular, steep and wide. it can.
