Description

Technical Field

[0001] This invention relates to the field of collection tools, and in particular to a tool for collecting organisms attached to reefs. Background Technology

[0002] Intertidal organisms in marine areas generally refer to snails or shellfish that attach to the surface or crevices of reefs. During the sampling of intertidal organisms in marine areas, it is common to encounter snails in the crevices of reefs and shellfish that are attached to the reefs. Simply picking them up by hand is quite difficult. Usually, a shovel is needed to scrape off the shellfish attached to the reefs before picking them up, and an iron hook is needed to hook the snails attached to the crevices of the reefs before picking up the fallen snails. Sampling operators need to carry at least a collection bag, an iron hook, and a shovel, which is very inconvenient. Furthermore, during the process of hooking snails, their uncontrollable falling trajectory sometimes results in them falling into the sea or other inconvenient locations, forcing sampling personnel to collect biological samples again, thus wasting marine biological resources. Existing technologies also include equipment for collecting shellfish or snails, such as a shallow-water snail and shellfish collection device (Chinese Patent Publication No. CN206547667U), which includes a float and a suction rake. The float is equipped with an engine, a water pump, and a vacuum pump, connected to each other. One end of the water pump has a soft water pipe, and the other end is connected to the vacuum pump via a water pipe. One end of the vacuum pump is connected to the suction rake via a water pipe, and the other end is connected to a storage net on the float via a water pipe. The float also has a push rod and a positioning rod fixing block, with the fixing rod connected to the positioning rod fixing block via a fixing shaft. The positioning rod has a hook, which is connected to the suction rake. However, this patent is not applicable to the collection of snails or shellfish on the surface or in the crevices of reefs, so a special biological collection tool for the intertidal zone of the sea needs to be designed. Summary of the Invention

[0003] This invention solves the problems of inconvenience in collecting intertidal organisms in marine areas due to the large number of tools required, as well as the inconvenience caused by the defects of the tools themselves. It proposes a tool for collecting organisms attached to reefs, which can achieve the shoveling, hooking and collection of shellfish or snails using a single tool.

[0004] To achieve the above objectives, the following technical solution is proposed:

[0005] A tool for collecting organisms attached to reefs includes a collection tube with a shovel head connected to the bottom of the tube via a handle. A collection hook is connected to the mouth of the collection tube, and the collection hook has a guide groove that forms a certain angle with the central axis of the collection tube. An opening is provided on the side of the collection tube near the bottom, and a collection net bag is provided on the opening.

[0006] This invention is applicable to intertidal organisms in marine areas, especially snails or shellfish attached to the surface or crevices of reefs. This application features a double-headed design. When attached to the reef surface and with sufficient operating space, the shovel head can be used to scoop off the snails or shellfish, with the collection hook acting as a handle for easy force application. When attached to reef crevices and with limited operating space, the operator can hold the handle, with the collection hook acting as the working part. The snails or shellfish are hooked into a guide trough, which then guides them into a collection cylinder, from which they fall into a collection net bag through the cylinder's opening. This prevents the snails or shellfish from falling into the sea or other inconvenient locations during hooking.

[0007] Preferably, the collecting cylinder is provided with a collecting tube communicating with the inside of the collecting cylinder. The collecting tube is provided with external threads and a collecting ring is threadedly connected to it. The outer surface of the collecting ring is provided with a groove, and a rubber ring is provided on the groove. The rubber ring is used to fix the opening of the collecting net bag to the collecting ring.

[0008] This invention features a collection ring to open the bag opening, while also allowing for separate collection net bags and collection cylinders. Once the collection net bag is full, the collection ring can be directly removed, enabling the collection net bag to be separated and facilitating the collection of sampled organisms.

[0009] Preferably, the bottom of the collection tube is provided with a guiding slope. The purpose of providing a guiding slope at the bottom of the collection tube of the present invention is to quickly guide snails or shellfish into the collection net bag when they enter the collection tube, so as to avoid them accumulating in the collection tube and causing already collected shellfish or snails to be thrown out of the collection tube during operation.

[0010] Preferably, the collection hook includes a first segment, a second segment, and an arc-shaped hook segment connected in sequence. The first segment is connected to the mouth of the collection tube and forms a certain angle with the axis of the collection tube, while the second segment is parallel to the surface of the mouth of the collection tube.

[0011] Preferably, the angle α between the first segment and the second segment is in the range of 100°-120°; the diameter of the arc-shaped hook segment is equal to the length of the second segment.

[0012] Preferably, the guide groove includes a first baffle and a second baffle, which are symmetrically arranged along the first segment and form a certain angle between them, with the angle ranging from 60° to 90°.

[0013] Preferably, the height of the first baffle and the second baffle is within the range of 0.5RR, where R is the radius of the collecting cylinder.

[0014] The purpose of setting the height range of the first baffle and the second baffle in this invention to 0.5RR is to avoid the guide groove being too wide laterally, so as to meet the working needs of more reef gaps.

[0015] Preferably, the handle is provided with a rubber anti-slip sleeve, and the surface of the rubber anti-slip sleeve is provided with several protrusions.

[0016] The purpose of the rubber anti-slip sleeve in this invention is to increase friction, making it easier for operators to grip the handle and perform shovel or hook operations.

[0017] Preferably, the arc-shaped hook segment has a first cutting surface and a second cutting surface, the included angle β of the first cutting surface and the second cutting surface is 30°-45°, the first cutting surface and the second cutting surface sandwich a first arc segment and a second arc segment, the first arc segment and the second arc segment have the same radius and the arc length of the first arc segment is greater than the arc length of the second arc segment, and the second arc segment is located inside the collection hook.

[0018] The purpose of providing a first and a second cutting edge on the arc-shaped hook segment of this invention is to reduce the contact area between the second arc segment and snails or shellfish, making it easier to hook down snails and shellfish.

[0019] The beneficial effects of this invention are: this invention combines the shovel head and hook into the same tool, and the hook and collection tube are specially designed to facilitate the collection of snails when they are hooked down. Attached Figure Description

Detailed Implementation

[0026] Example:

[0027] This embodiment proposes a tool for sampling and collecting reef-attached organisms, referencing... Figure 1 and Figure 2The system includes a collection cylinder 3, with a shovel head 1 connected to the bottom of the cylinder via a handle 2. A collection hook 4 is connected to the mouth of the collection cylinder 3, and the collection hook 4 has a guide groove 5 at a certain angle to the central axis of the collection cylinder 3. An opening is located on the side of the collection cylinder 3 near the bottom, and a collection net bag 7 is installed on the opening. (Reference) Figure 3 The collecting cylinder 3 has a collecting tube 32 communicating with its interior. The collecting tube 32 has external threads and is threadedly connected to a collecting ring 33. The outer surface of the collecting ring 33 has a groove, and a rubber ring 34 is mounted on the groove. The rubber ring 34 is used to fix the opening of the collecting net bag 7 to the collecting ring 33. The bottom of the collecting cylinder 3 has a guide slope 31. (Reference) Figure 4 The collection hook 4 includes a first segment 41, a second segment 42, and an arc-shaped hook segment 43 connected sequentially. The first segment 41 is connected to the mouth of the collection cylinder 3 and forms a certain angle with the axis of the collection cylinder 3. The second segment 42 is parallel to the surface of the mouth of the collection cylinder 3. The angle α between the first segment 41 and the second segment 42 ranges from 100° to 120°; the diameter of the arc-shaped hook segment 43 is equal to the length of the second segment 42. The guide groove 5 includes a first baffle and a second baffle, which are symmetrically arranged along the first segment 41 and form a certain angle ranging from 60° to 90°. The height of the first baffle and the second baffle ranges from 0.5RR, where R is the radius of the collection cylinder 3. The handle 2 is provided with a rubber anti-slip sleeve 6, and the surface of the rubber anti-slip sleeve 6 is provided with several protrusions. (Reference) Figure 5 The arc-shaped hook segment 43 is provided with a first cutting surface and a second cutting surface. The included angle β between the first cutting surface and the second cutting surface is 30°-45°. The first cutting surface and the second cutting surface sandwich a first arc segment and a second arc segment. The first arc segment and the second arc segment have the same radius, and the arc length of the first arc segment is greater than the arc length of the second arc segment. The second arc segment is located inside the collection hook 4.

[0028] The working process of this embodiment is as follows:

[0029] 1. When the collected material is attached to the surface of the reef and there is enough space to operate, the snail or shellfish can be scooped off using the shovel head 1. At this time, the collection hook 4 acts as the handle of the shovel. The operator holds the handle with one hand and the collection hook 4 with the other hand to perform the shoveling action.

[0030] 2. When the collected material is attached to the crevices of the reef and there is insufficient operating space, the operator can hold the handle 2. At this time, the collection hook 4 acts as the working part, hooking the snails or shellfish into the guide trough 5. The guide trough 5 then guides the snails or shellfish into the collection tube 3, and then drops them into the collection net bag through the opening of the collection tube, thus preventing the snails and shellfish from falling into the sea or other inconvenient locations when hooked.

[0031] This invention is applicable to intertidal organisms in marine areas, especially snails or shellfish attached to the surface or crevices of reefs. This application features a double-headed design. When attached to the reef surface and with sufficient operating space, the shovel head can be used to scoop off the snails or shellfish, with the collection hook acting as a handle for easy force application. When attached to reef crevices and with limited operating space, the operator can hold the handle, with the collection hook acting as the working part. The snails or shellfish are hooked into a guide trough, which then guides them into a collection cylinder, from which they fall into a collection net bag through the cylinder's opening. This prevents the snails or shellfish from falling into the sea or other inconvenient locations during hooking.

[0032] The present invention provides a collection ring 33 for opening the bag opening, and at the same time realizes the separate setting of the collection net bag 7 and the collection cylinder 3. When the collection net bag is full, the collection ring can be directly removed to separate the collection net bag, which facilitates the collection of sampled organisms.

[0033] The purpose of providing a guide slope 31 at the bottom of the collection tube 3 of the present invention is to quickly guide snails or shellfish into the collection net bag when they enter the collection tube, so as to avoid them accumulating in the collection tube and causing the already collected shellfish or snails to be thrown out of the collection tube during operation.

[0034] The purpose of setting the height range of the first baffle and the second baffle in this invention to 0.5RR is to avoid the guide groove being too wide laterally, so as to meet the working needs of more reef gaps.

[0035] The purpose of setting the rubber anti-slip sleeve 5 in this invention is to increase friction and make it easier for operators to hold the handle 2 to perform shovel or hook operations.

[0036] The purpose of providing a first cutting edge and a second cutting edge on the arc-shaped hook segment 43 of this invention is to reduce the contact area between the second arc segment and snails or shellfish, making it easier to hook snails and shellfish.
