Description

The present invention relates to a mineral picking tool for picking minerals such as jade washed ashore on the beach.

In order to collect minerals such as jade washed ashore on the beach, it is necessary to select the target minerals from many rocks using rakes and shovels. In the case of rare minerals, not only must the sorting operation be repeated many times, but work must be done while crouching on the beach, which is quite hard work. Therefore, in order to be able to do this work while standing, a self-made tool called a "jade stick" was used, in which a "basket" such as a ladle with a hole used for cooking or a colander was fixed to the tip of a long stick. ing. According to this, the sorting work can be efficiently performed while standing.

By the way, in the above-mentioned tool having a basket attached to the tip of a long stick, when the basket is inserted between sand or rocks and is to be scraped up, considerable force is applied to the basket and the stick. Join. In addition, since a considerable amount of weight is applied to the basket portion when picking up the rock from the water, the tool is required to have relatively high rigidity. Cleaning tools and farming tools for scooping up trash in gutters are known as such tools having baskets attached to long sticks with relatively high rigidity.

For example, Patent Document 1 discloses a gutter cleaning tool used for scooping and cleaning filth such as sludge and garbage accumulated in gutter, in which the lower end of a grip made of a long metal pipe is Section 1 discloses a cleaning tool in which a plate is bent to ensure rigidity and a base of a dustpan-like scooping body is fixed. By forming a plurality of water passage holes in the scooping body, the water of the dirt scooped into the scooping body can be drained from the water passage holes, and the solid content can be recovered as much as possible.

Patent document 2 discloses a gutter cleaning tool in which a net-like basket is attached to the tip of a long rod. A reinforcing frame is provided by attaching a cutting edge formed by folding a metal plate to the tip edge and upper edge of the bottom member which is a net-like basket. According to this, it is possible to increase the strength while being a net-like basket portion that is superior in drainability to a basket portion in which water passage holes are provided in a plate-like member.

Further, Patent Document 3 discloses an agricultural tool having a shape similar to that of Patent Document 1, in which the bottom plate of the hoe portion has a side wall surface formed by bending a metal plate at the tip of a long stick, and a sieve hole is provided in the bottom plate of the hoe. It discloses a plow and agricultural tool. The hoe portion is made of a stainless steel plate from the viewpoint of enhancing strength and durability, and has a certain strength suitable for use as a hoe for plowing soil.

A jade rod in which a cage is fixed to the end of a long rod can capture minerals that are far away from the hand of the user (mineral extractor). Therefore, it will be possible to search for minerals in the water slightly offshore from the beach that other mineral collectors have not searched. On the other hand, the water was several tens of centimeters deeper than the water's edge, and the resistance of the water increased rapidly, increasing the load on the cage, and lifting the minerals out of the water became even more laborious.

The present invention has been made in view of the above circumstances, and its object is to fix a catching part to the tip of an elongated rod for collecting minerals such as jade washed ashore on the beach. To provide a mineral picking tool capable of simplifying the picking operation.

A mineral picking tool according to the present invention is a mineral picking tool that has a trapping part made of a substantially rectangular metal flat plate fixed to the end of a long bar for picking out minerals in water separately from rocks at the coastal beach. A belt-shaped side wall is provided along both sides of the rectangular metal flat plate, and a plurality of through holes are provided between the side walls to penetrate the metal flat plate. When the flat metal plate is obliquely submerged in the water from the rectangular bottom edge of the flat metal plate, a water flow directed toward the flat metal plate passes through the through-holes, and the mineral and/or rock flows into the through-holes. The direction of the water flow is changed along the metal flat plate toward the rectangular upper edge by changing the direction of the water flow to change the direction of the water flow to move the mineral and/or rock from the metal to the metal flat plate. It is characterized by rolling on a flat plate.

According to this feature, it is possible to roll minerals and/or rocks on the metal flat plate, and it is possible to determine whether or not they contain highly light-reflecting jadeite without taking them out of the water, and collect them. It makes the operation easier.

In the above-described invention, the space between the side walls of the flat metal plate may be colored to lose metallic luster. According to this feature, it is possible to more easily determine whether or not jadeite, which has high light reflectivity, is included, thereby simplifying the collecting operation.

In the above-described invention, a plurality of through holes may be arranged on the main surface of the flat metal plate at intervals in a direction from the rectangular lower end side to the rectangular upper end side. Further, the through-hole may have a substantially rectangular opening with a width of 5 mm or more on the main surface of the metal flat plate, and the long side may be arranged along the side wall. Further, the through-hole may be characterized by having a circular opening with a diameter of 5 mm or more on the main surface of the metal flat plate. According to this feature, the minerals and/or rocks can be stably rolled on the metal flat plate, it is possible to more easily determine whether or not the minerals and/or rocks contain highly reflective jade, and the extraction operation can be performed more easily. It makes it simple.

In the above-described invention, the space between the side walls of the flat metal plate may be colored to lose metallic luster. According to this feature, it is possible to more easily determine whether or not jadeite, which has high light reflectivity, is included, thereby simplifying the collecting operation.

FIG. 10 is a perspective view of a main part of a mineral picking tool in another embodiment according to the present invention; FIG. 4 is a diagram showing a water flow when minerals and/or rocks are extracted by a mineral extractor;

A mineral picking tool as a representative example of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

Here, the inventors of the present application have empirically confirmed that jadeite has luster and that jadeite exists in an angular shape because its hardness is higher than that of ordinary rocks. Although similar to the conventional network structure for sieving liquids (eg, seawater) and solids (minerals and rocks), the present invention has been made by changing this from a completely different point of view.

As shown in FIG. 1, a mineral extractor 10 has a handle 2 made of an elongated rod that can be expanded and contracted at a joint 2a, and a catching part 1 fixed to the tip of the handle 2. As shown in FIG. The catching portion 1 is composed of a metal flat plate 11, and a handle 2 is fixed to the rear end of the metal flat plate 11 so as to extend in a direction substantially perpendicular to the main surface thereof. The mineral picking tool 10 is used for picking up minerals washed ashore on the beach, especially minerals in water on the beach. In other words, the mineral extractor 10 is used by the user (mineral extractor) with the handle 2 held by the user (mineral extractor) directed obliquely downward so that the tip projection 15 of the trapping part 1 can be thrust into the bottom of the water. At this time, in the trapping unit 1, gravel-like minerals and/or rocks (hereinafter referred to as minerals, etc.) can be placed and trapped thereon, and in particular minerals, etc. with a relatively angular shape can be trapped. However, the details will be described later.

As shown in FIG. 2, the trapping portion 1 includes a substantially rectangular flat metal plate 11, and strip-shaped side walls 12a to 12d extending back and forth along both sides 11a and 11b of the flat metal plate 11 are provided. The side walls 12a to 12d can be formed, for example, by using a partition plate made by bending a metal plate so that two flat plate portions are perpendicular to each other to form a substantially L-shaped cross section. The main surface of one flat plate portion of the partition plate is fixed so as to be in contact with the upper surface of the metal flat plate 11, and the other flat plate portion is erected toward the upper side of the metal flat plate 11 as a side wall 12a. In addition, the end portion of the flat metal plate 11 may be bent to be integrally molded. The side walls 12a and 12b and the side walls 12c and 12d are spaced apart from each other, and the rectangular flat metal plate 11 is arranged so as to have slits 13 in the central portions of both sides 11a and 11b.

The catching part 1 has a plurality of tip protrusions 15 extending further toward the tip from the tip of the metal flat plate 11 . The tip projection 15 can easily enter between minerals and the like when the tip of the trapping part 1 is thrust into the bottom of the water, and can promote the movement of minerals and the like between the side walls 12a and 12b and the side walls 12c and 12d. As a result, the tip of the flat metal plate 11 can be guided between minerals or the like. In addition, although two tip projections 15 are provided in the drawing, the number may be three or more.

The metal flat plate 11 is provided with a plurality of through holes 14 spaced from the rectangular lower end side to the rectangular upper end side between the side walls 12a and 12b and the side walls 12c and 12d. The through-holes 14 have an upper limit in size so as to capture the target minerals, etc., and the shape and arrangement of the through-holes is such that the water flow can be changed by blocking the through-holes 14 with minerals, etc., which will be described later. , aperture ratio and number are selected. The through-holes 14 may be arranged in a houndstooth position on the main surface of the flat metal plate 11 (FIG. 3(a)) or may be arranged in a lattice position (FIG. 3(b)). A mineral or the like arranged in one through-hole 14, particularly an angular mineral or the like, floats from the one through-hole 14 due to the flow above the metal flat plate 11, but the other through-holes 14 are arranged along the flow. As a result, it is likely to move to the other through-hole 14 and be captured. It is also preferable to provide projections at the long side ends of the through-holes 14 so that minerals and the like can be easily captured. When the center lines of the through-holes 14 arranged in the longitudinal direction are arranged in a houndstooth lattice position in which the through-holes 14 are shifted by about half the length of the through-holes 14 for each horizontal row, the opening area is reduced compared to the lattice position, but the water flow is reduced. The change is more likely to occur, and rolling on the metal flat plate 11 such as minerals is more likely to occur.

It should be noted that the standard size of minerals, etc., the water flow, and the tendency of the number of minerals, etc. to be captured at one time differ depending on the place where minerals, etc. are collected, and the angle of the handle 2 varies depending on the user's height, etc. changes, and as a result, the angle from the vertical plane of the metal plate 11 also changes. Therefore, since the easiness of repeating closing and opening of the through-hole 14 changes, the size of the through-hole 14 cannot be generally determined, but it is generally as follows.

For example, the through-hole 14 has a substantially rectangular cross section with a substantially rectangular opening (the corners may be chamfered R) on the main surface of the metal flat plate 11, and extends along the side walls 12a to 12d. Multiple sides are provided. In this case, the width (short side length, W in FIG. 3A) of the through hole 14 is 3 mm or more and 10 mm or less, the length (long side length, L in FIG. 3A) is 10 mm or more and 20 mm or less, In particular, it is preferable to set the width to 5 mm or more so that a part of angular minerals or the like can be accommodated. The aperture ratio, which is the ratio of the area of the through holes 14 to the area of the flat metal plate 11, is arbitrary. On the other hand, the through holes 14 are easily clogged with minerals or the like, and if the water flow is moderate, the minerals or the like can be relatively easily rotated by the change. Conversely, if the opening ratio is too large, the through holes 14 will not be sufficiently clogged with minerals or the like, and the flow of water will change less, so rotation will not be obtained. Therefore, the aperture ratio is generally set to 20 to 70%, preferably about 20 to 50%.

Moreover, as shown in FIG. 4, the through-hole 14 may be a hole having a substantially circular cross-section having a substantially circular opening on the main surface of the flat metal plate 11. 5 mm or more so that a part of minerals, etc. can be accommodated. However, although it is preferable when the sizes of the minerals to be collected are uniform, when the sizes of the minerals are not uniform, the through holes 14 having a substantially rectangular cross section allow the minerals to roll. can be captured stably. In this example, the through holes 14 are arranged at lattice positions on the main surface of the metal flat plate 11, but they may be arranged at staggered lattice positions. Further, by providing a flange-like convex wall of about 1 mm along the short side of the longitudinal end of the through hole 14, minerals and the like can be trapped more satisfactorily. Such a flange-like portion may be a burr during processing of the through-hole 14, and may be formed by removing only a part of the burr formed on the entire peripheral edge of the through-hole 14 and removing the rest.

The side walls 12a-12d are provided so as to prevent minerals and the like from scattering from the surface of the metal plate 11 to the sides, and to form a water flow along the extending direction of the side walls 12a-12d. By providing the side walls 12a and 12b and the side walls 12c and 12d as independent side walls and providing a gap between them, it is possible to prevent minerals and the like from suddenly flowing out of the metal plate 11 due to the water flow. As a result, more rotation of minerals and the like on the metal flat plate 11 can be obtained.

Further, each of the side walls 12a-12d may also be provided with a side through-hole 16. As shown in FIG. The side walls 12a to 12d limit the lateral movement of minerals and/or rocks to prevent them from falling out of the trapping portion 1, while the slits 13 and the side through-holes 16 allow the water on the metal plate 11 to flow laterally. can flow to

A method of using the mineral picking tool 10 will be described with reference to FIG. For convenience of explanation, the side walls 12a to 12d are omitted in FIG.

As shown in FIG. 5(a), first, the catching part 1 is arranged so that the tip projection 15 thereof can be abutted against the water bottom at the edge of the waves. At this time, the user holds the handle 2 and stands facing the direction of the undertow, that is, the direction from the coast to the sea. Then, the catching portion 1 is positioned forward (to the left in the plane of the drawing) obliquely downward. That is, the side walls 12a to 12d (see FIG. 2 or 3) are directed upward, and the flat metal plate 11 is obliquely submerged in water from the rectangular bottom edge of the flat metal plate 11. Then, as shown in FIG. At this time, by changing the length of the handle 2 with the joint 2a, the oblique angle of the flat metal plate 11 can be changed, which facilitates the work.

Then, when the undertow occurs, the water W moves forward with respect to the trapping portion 1 . At this time, the water flow directed toward the metal flat plate 11 passes forward through the through holes 14 (see FIG. 2). Then, the minerals and the like M on the bottom of the water are drawn into between the side walls 12a and 12b and the side walls 12c and 12d (see FIGS. 1 and 2) and onto the metal plate 11 together with the water flow. The mineral or the like M is arranged on the flat metal plate 11 so as to partly enter the inside of the through-hole 14 while the force of being pressed against the upper surface of the flat metal plate 11 is applied to the water flow. That is, relatively angular minerals and the like are trapped in the through holes 14 , and relatively round minerals and the like tend to flow over the metal flat plate 11 . In addition, the user operates the handle 2 to change the length of the handle 2 with the joint 2a so that the mineral or the like M can be easily drawn into the through hole 14, and the inclination of the trapping portion 1 is reduced. Alternatively, the catching portion 1 may be drawn.

As shown in FIG. 5B, the minerals M are arranged on the upper surface of the flat metal plate 11 and close the through holes 14 . It should be noted that the blockage referred to here does not have to be a complete blockage, but at least narrows the flow path of the water passing through the through hole 14 to change the direction of the water flow. Then, the movement of the water W due to the undertow changes the direction of the water flow along the upper surface of the metal flat plate 11, which is the direction in which the side walls 12a to 12d extend. As a result, the force of pressing the mineral or the like M against the upper surface of the metal flat plate 11 is reduced, and the force in the direction along the upper surface of the metal flat plate 11 is applied by the water flow while being in a state where it is easy to roll.

Then, as shown in FIG. 5(c), the mineral or the like M can be rolled on the metal flat plate 11 by the above-described water flow. By rolling the minerals M, it is possible to determine whether or not they contain jade, which has high light reflectivity, without taking them out of the water. At this time, if the plane portion of the metal flat plate 11 is colored to lose at least the metallic luster, the light reflection can be more easily confirmed. Dark colors such as black and gray are suitable for coloring. In addition, by rolling the minerals M, it is possible to increase the surface area of the minerals M facing the user, and the jadeite to be collected is exposed only on a part of the surface of the rock. Even rocks containing no jade can be easily identified. By these means, the target minerals can be sorted out from other rocks, and the operation of extracting the target minerals can be simplified.

When the mineral or the like M rolls, it loosens the blockage described above and causes a water flow passing through the through hole 14 of the metal plate 11 . Then, the mineral or the like M is again arranged on the flat metal plate 11 and rolled. In this way, the undertow can repeat the operation of lining up the minerals and the like M and rolling them. It should be noted that the user may move the catching portion 1 rearward to generate a relatively forward water flow to perform the same operation.

Although the embodiments according to the present invention and modifications based thereon have been described so far, the present invention is not necessarily limited to these examples. Also, those skilled in the art will be able to find various alternatives and modifications without departing from the spirit of the invention or the scope of the appended claims.
