Description

The present invention relates to a shaving tool, and more particularly to a shaving tool suitable for shaving barnacles and the like attached to the crust of rock oysters that are irregularly raised.

In recent years, the culture technology of rock oysters has been established, and rock oysters are cultivated in various places including the Oki Islands in Shimane Prefecture. For aquaculture, the underwater suspension system is mainly adopted, and at the time of shipment, several rock oysters that adhere to the rope are broken into pieces and separated into individual pieces. Scrape off.

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

However, since the impact driver has only one hit point, it has a problem that the oyster shell is easily damaged and that the impact driver is not necessarily suitable for shaving surface deposits of rock oysters, which has a relatively large area.

On the other hand, there is also known a sharpening tool of a chisel type for forming a design on an outdoor wall of a house or removing rust of metal. This is a device that oscillates a plurality of elongated chisel bars (needle chisel) which are close to each other and have a short stroke to scrape the tip abutting portion into a relatively wide area (Patent Document 1). ~ 5).

However, when targeting irregularly shaped and raised objects such as rock oyster shells, a short stroke does not hit all the needles and impairs the large area shaving process. There was a problem.

FIG. 1 is a plan view of a sharpening tool according to the present invention, that is, a sharpening tool for accommodating a plurality of wire chisel wires having a predetermined thickness, which is a slender wire chisel unit and is used as a bundle. It is explanatory drawing which showed the structural example of the ingredient|tool. In the figure, it is drawn as a perspective view of the posture in which the needle chisel is directed upward. In addition, the needle chisel draws only one needle chisel unit. FIG. 2 is a bottom view of the needle chisel unit. The drawing of the tatami and needle chisel is omitted. FIG. 3 is a sectional view showing an outline of the structure of the needle chisel unit. FIG. 4 is a conceptual diagram showing how each of the needle chisel units follows the surface of the object to be scraped to create a height difference. 3 and 4, the drawing of the air supply hose and the like is omitted.

The sharpening tool 1 has seven needle chisel units 10 and a unit holder 20 for inserting the needle chisel units 10 as main components, and each of the needle chisel units as shown in FIG. By adopting a configuration in which 10 freely moves back and forth in the axial direction (slides), it follows the surface irregularities of the object to be cut, and achieves efficient cutting.

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, and the needle chisel 12 is minutely moved by air pressure and spring force. Vibrate or finely vibrate (Fig. 3). Specifically, it is as follows.

The needle holder 11 is an elongate hollow cylinder with a bottom that constitutes the housing of the needle chisel unit 10. As shown in FIG. 1 or 2, the outer shape is a regular hexagonal prism, and the bottom surface 111 thereof has a plurality of needle holes 112 in the longitudinal direction (axial direction). The needle chisel 12 is inserted through the needle hole 112, and seven needle holes 112 are provided for the object rotated by 60° with respect to the shaft. Due to this positional relationship, the adjacent needle holes 112 are all equidistant. As will be described later, the needle chisel units 10 are in contact with each other on the side surfaces of the housing, but the outer needle holes 112 belonging to the respective needle chisel units 10 are arranged to be substantially at this distance. In other words, it can be said that in the shaving tool 1, the needle chisel 12 is arranged almost uniformly regardless of the location (FIG. 2).

The needle chisel 12 is an elongated rod-shaped high-strength metal rod that is inserted into each of the needle holes 112. Here, a hard steel wire is used as the material. The base end 121 is larger than the needle hole 112, and the base end 121 side is housed 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 and presses against the surface to be scraped, and the surface is scraped.

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 vibrating slightly in the axial direction. Specifically, it is an integral body having the shaft rod portion 131 and the striking face portion 132, and the striking face portion 132 is substantially inscribed in the needle holder 11 and substantially closes the bottom face 111. The shaft rod portion 131 connected to this has a smaller diameter than the striking face portion 132, and the coil spring 15 is inserted in this space formed between the shaft rod portion 131 and the needle holder 11.

By inserting the coil spring 15 in the part where the diameter of the anvil 13 is reduced, it is possible to avoid the radial protrusion that occurs when the coil spring is arranged outside the needle holder 11 or around the needle chisel 12. .. This makes it possible to bring the needle chisel units 10 into close contact with each other and smoothly move them back and forth (slide) in the axial direction without interfering with each other. In addition, the needle chisel 12 can be arranged even near the periphery of the needle chisel unit 10, and as described above, the needle chisel 12 of the adjacent needle chisel unit 10 is also included. Therefore, the arrangement of the needle chisel 12 can be made substantially uniform.

The air supply unit 14 is disposed on the base end side of the shaft rod portion 131 of the anvil 13, and the anvil 13 vibrates due to the air pressure of the air sent 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 the striking face portion 132 from the bottom face 111 (to try to float), and the coil spring 15 pushes the striking face portion 132 toward the bottom face 111 side. Although illustration is omitted, air escape holes are provided on the side surface of the needle holder 11 and the striking surface portion 132, so that microvibration continues without both forces being balanced.

It should be noted that in actual driving, the seven needle chisel 12 vibrate apart due to the impact vibration of the striking surface portion 132 on the base end 121, and effective cutting is realized.

The unit holder 20 accommodates and inserts seven needle chisel units 10 as shown in the drawing, and the respective needle chisel units 10 can freely move in the axial direction with respect to each other and with respect to the unit holder 20. It is like this. As a result, the needle chisel unit 10 can hit 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 the cutting that follows the surface. FIG. 4 exemplifies the follow-up state.

For actual shaving, the user applies the shaving tool 1 to the shaving target, for example, the crust of rock oysters so that the needle chisel unit 10 does not fall out of the unit holder 20, and starts vibration. The work is performed so that the unit holder 20 is appropriately moved in a circle to hit the needle chisel 12 over the surface to be ground. Since each needle chisel unit 10 follows the surface irregularities, efficient scraping is performed.

As described above, according to the sharpening tool 1 of the present invention, even if the unevenness of the surface to be cut is steep, each needle chisel unit 10 changes its height to follow the unevenness, so that the conventional needle Effectively cuts a large area than chisel and has excellent workability.

The present invention is not limited to the above aspect.
For example, a locking portion may be provided on the upper part of the needle chisel unit 10 (the upper part of the needle holder 11) to regulate the fall of the needle chisel unit 10 from the unit holder 20.

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

Further, a mechanism may be adopted in which the air from the air supply unit 14 pushes the striking face portion 132 toward the bottom face 111 side, and the coil spring 15 pulls the striking face portion 132 back from the bottom face 111 to continue the vibration. Alternatively, a striking portion may be separately provided and the vibration may be transmitted to the anvil 13 to generate vibration regardless of the air pressure. Further, the anvil 13 itself may be a vibrating body.

<Shaving equipment>
Next, the shaving device will be described. Here, a shaving device for shaving deposits on the surface of the shell of rock oyster will be described. FIG. 5 is an explanatory view showing an example of the shaving device of the present invention. The scraping device 5 includes a scraping tool 50, an endless belt 60, and a scraping tool adjusting base 70. Here, regarding the shaving tool 50, the same components as those of the above-described shaving tool 1 are denoted by the same reference numerals, and the description thereof will be omitted.

The sharpening tool 50 includes a needle chisel unit 10 and a unit holder 51.
The unit holder 51 allows the needle chisel unit 10 to be inserted through 6 units×3 rows=18 units (FIG. 5A). As shown in FIG. 5b, a bottom surface 511 having an edge of a predetermined width along the hexagonal pattern and punching out the middle side of the pattern is provided on the lower side thereof (in FIG. 5c, by a dotted line). , A side view of the needle chisel unit 10 is shown). Due to the bottom surface 511, the needle chisel unit 10 does not fall off from the unit holder 51, and each of the needle chisel 12 does not come into contact with the bottom surface 511, but is scraped downward. That is, in the needle chisel unit 10, the bottom 511 prevents the needle holder 11 from slipping out, and further lowering is restricted. 5A and 5B show that the needle chisel unit 10 is completely dropped 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 uniform).

The unit holder 51 has a rectangular parallelepiped outer shape as shown in the figure, but is held above the endless belt 60 by the scraping tool adjustment base 70 and oriented at a predetermined angle with respect to the transfer direction of the endless belt 60. Is adjustable. Specifically, the needle chisel unit 10 is oriented at a predetermined angle of 10° to 40° on the upstream side of the transfer of the endless belt 60. FIG. 5b shows a mode in which the bolts 71 are fixed at an angle of about 25°. The inclination angle is set according to the amount of the adhered substances in the shell and the transfer speed. This is because the crust is roughly mountainous, and by orienting so as to meet the transfer, efficient shaving is realized.

In driving, as described above, the shaving tool 50 is oriented at a predetermined angle and fixed by the fixing bolts 71, then the air supply of the air supply unit 14 is started, and then the endless belt 60 is driven, The rock oysters are sequentially placed on the upstream side of the endless belt 60. The air supply tube and the like are not shown.

In addition, due to the orientation, the upper half of the rock oysters can be scraped well. Therefore, the shaving device 5 is passed twice to scrape the entire upper surface (shell) of the rock oyster. You may make it pass multiple times. Depending on the mode of use, another shaving tool 50 may be provided downstream, and a rotating mechanism for rotating the rock oysters 180° may be provided between them to scrape the entire surface. Alternatively, the lid shell may be inverted and the lid shell may be scraped.

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

The present invention is not limited to rock oysters, and irregularities on the surface are irregular and steep, and can be used when performing efficient shaving using a needle chisel, for a large-area shaving target. it can.
