Description

The present invention relates to a tool for taking shellfish such as clams and swordfish that inhabit the sea and rivers.

Traditionally, a shell collecting Jollen is a tool that captures shellfish that inhabit the seabed and riverbed, and its shape is composed of pointed nails and mesh ridges, and the shell collecting Jollen is used for work. Then, many shellfish can be harvested in a short time. The method of use is to dig up the bottom surface at the tip of the nail, accumulate shellfish and earth and sand together in the cage, and shake Jollen to remove sand, mud, pebbles, etc. from the mesh, equivalent to shellfish Only stones and foreign objects that are larger than the size of the remaining shells can be easily distinguished from shells and stones and foreign objects.

In the conventional technology, the Johlen's bowl-shaped portion has a structure in which a rod-shaped material is welded, which takes time and labor to manufacture. In addition to this structure, there is a combination of a fence frame and a net, etc., but regarding the shaking of sand, mud, pebbles, etc., the amount of shaking is limited depending on the size of the pebbles and the size of the mesh. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a shell collecting jolen aiming at simplifying the structure, reducing the manufacturing cost, reducing the weight, and improving the workability of the shell removing operation.

The pointed claw provided at the tip of a conventional shell-taking jolen has a structure in which a plurality of claws are welded to a base material, and it takes time to manufacture. Therefore, an object of the present invention is to provide a shell collecting jolen that simplifies the structure and reduces the production cost.

The shell of the conventional shell collecting Jollen has a single net structure, and shells other than sand, mud, and pebbles that are shaken off from the mesh remain in the cage. Therefore, an object of the present invention is to provide a shell collecting Jollen that can be separated so that a shell and a stone larger than the shell are not crossed.

The conventional shell-removing Jollen is fixed to the Jollen main body and the handle that is operated by hand, and is fastened with bolts and nuts. In addition, the integrated shape is inconvenient to carry and store. Accordingly, an object of the present invention is to provide a structure that can easily separate the Jollen main body and the handle.

The conventional use of shellfish Jollen is to place the Jollen main body on the bottom, hang the top end of the handle on the shoulder, pull it by hand at the middle point, but the resistance of the force to dig up the bottom is large, Since the stress is received by the hand and shoulder, the labor applied to the hand and shoulder is large. Therefore, an object of the present invention is to provide a method that can be pulled more easily by a human body.

In order to solve the above-mentioned problems, the first invention is that Joren's rod-shaped rod barrel portion 5 and rod left side surface portion 6 and rod right side surface portion 7 are formed by punching a thin metal plate to form rectangular holes 10. The ridge is characterized by the structure of a plurality of plate-like nets. Further, it is a shell collecting jolen that joins the joint portion of the jolen frame 1 and the rod body portion 5, the rod left side surface portion 6, and the rod right side surface portion 7 by welding to make a lightweight and robust object.

In order to solve the above-mentioned problems, the second invention is characterized in that the Jollen claw 4 is formed by cutting a metal plate. The part of the nail itself is a shell collecting Jollen that is not welded.

In order to solve the above-mentioned problems, the third invention provides an intermediate mesh plate 20 in the middle of the Jollen's heel portion, and the intermediate mesh plate 20 has a mesh size that allows large shells to pass through. Keep stones and foreign objects away. The intermediate mesh plate 20 is set to the set position 30a when the seabed or the riverbed is dug up, and is set to the offset position 30c when the shellfish are harvested. The setting and offset of the intermediate mesh plate 20 has a structure that can be easily operated by reversing the intermediate mesh plate 20 with the slide. When the shells are dug up and Jollen is raised, the stones and foreign matter that are in front of the intermediate mesh plate 20 are only large and can be easily discarded. After discarding, the intermediate mesh plate 20 is offset from the set position 30a. The shell is reversed to the position 30c so that the shell can be easily taken out, and the shells, stones, and foreign matter collected in the basket are sorted and harvested. This is a shell collecting Jollen characterized in that an intermediate mesh plate 20 is provided in the middle middle of Jollen's jar.

In order to solve the above-mentioned problems, the fourth invention is that the handle 2 attached to the joren has the handle 2 as a pipe-like object, and the connecting pipe 3 processed with a pipe having a thickness into which the handle 2 can be inserted. It can be easily disassembled by loosening the fixing bolt 3a by inserting the handle 2 into the connection pipe 3 and tightening the fixing bolt 3a. A shell collecting Jollen characterized by a connecting pipe 3.

In order to solve the above-described problems, the fifth aspect of the present invention is to connect the chain 9 to the eye plate 8 attached by welding to the lower surface of the connection pipe 3 and pull the end of the chain 9 on the waist to pull the hand and shoulder. Such stress is reduced. It is a shell collecting Jollen characterized by providing an eye plate 8.

According to the first aspect of the present invention, the collar body portion 5, the left side surface portion 6 and the right side surface portion 7 of the collar portion of Jollen are plate-like nets obtained by punching a plurality of rectangular holes 10 in a thin metal plate. , The time and effort of manufacturing is reduced. Moreover, since the Jollen frame 1, the rod body 5, the rod left side surface portion 6, and the rod right side surface portion 7 are component units, they can be easily joined together by welding, and the material is a thin metal plate. Weight reduction is also realized. In addition, the shell collecting operation is easy to handle due to the light weight of the shell collecting jolen, and the work on the human body is reduced and the workability is improved.

According to the second aspect of the invention, the metal plate is cut out when the claw 4 is manufactured, and the labor for manufacturing is reduced.

According to the third aspect of the invention, by providing the intermediate net 20 in the middle of Jollen's jar, stones and foreign materials larger than large shells do not enter the jar, so those unnecessary items can be easily removed. Can be removed. In addition, the intermediate screen 20 is movable, and can be easily moved from the set position 30a to the offset position 30c by reversing and reversing, so that shells and unnecessary items can be easily sorted, and the time for shell removal work can be reduced. The labor force will be reduced.

According to the fourth invention, since the Jollen main body and the handle 2 can be easily separated, it is convenient to carry and saves space.

According to the fifth aspect of the present invention, the shell collecting jolen can be pulled by the waist of the human body, the labor of the shell collecting operation is reduced, and the workability is improved.

Operation in each direction of the set position 30a, the intermediate position 30b, and the offset position 30c of the intermediate net plate 20 is shown in a side cross-sectional view of the shell collecting joren.
