Description

Technical Field

[0001] This utility model belongs to the technical field of species sorting devices, specifically relating to a fish species sorting device suitable for field surveys. Background Technology

[0002] Fish sorting devices are tools and equipment used in field fish resource surveys, ecological research, or fisheries management activities to classify, measure, and count caught fish. The design and application of these devices are of great significance for accurately understanding the population structure, quantity, and health status of fish in specific waters.

[0003] Fish surveys typically use tools such as buckets and stainless steel basins to collect fish, and square pans to classify, count, and weigh them. These tools are numerous and vary in size, making them inconvenient to operate and difficult to carry. They are also prone to data or sample omissions due to negligence, affecting the accuracy and completeness of the survey results. The entire process is inefficient and time-consuming.

[0004] Chinese patent application CN116138203A (published on May 23, 2023) discloses a portable fish collection device with a sorting function, which includes a barrel body and a sorting mechanism assembled on the top of the barrel body. The sorting mechanism includes a top cover and a limiting ring installed at the bottom of the top cover. A spiral groove is opened on the top of the top cover, and a spiral slide is installed inside the spiral groove. Screening components are installed at equal intervals along the circumference of the top of the spiral slide.

[0005] Although patent application CN116138203A aims to provide a convenient fish collection device with classification capabilities, its structure is relatively complex, comprising multiple components such as a spiral chute, screening parts, and buoyancy components. This makes it difficult to maintain and unsuitable for field fish surveys and collection. Furthermore, the spiral chute mentioned in the patent document relies on the fish's own gravity to enter and classify the fish. This means that lighter fish may get stuck in the channel, leading to missed samples. More importantly, the device can only classify fish by size, not by species, requiring an additional manual secondary classification step. In practical applications, this device may have certain limitations.

[0006] Therefore, the above situation urgently needs to be addressed. Utility Model Content

[0007] To address the aforementioned issues, this application proposes a fish sorting device suitable for outdoor surveys. The device includes a handle, casters, a device body, an inner ring assembly, a connecting block, a connecting adjustment mechanism, a collection area, a sorting area, and a sorting container. The device body has handles connected to both sides and casters installed at the bottom.

[0008] The device body is provided with an inner ring component, a collection and holding area, and a classification and holding area. The inner side of the inner ring component is the collection and holding area, and the outer side is the classification and holding area.

[0009] The inner ring assembly is suspended within the device body via a connecting block;

[0010] The connecting block is provided with a connecting adjustment mechanism on both sides, and a classification and holding box is installed in the classification and holding area. The classification and holding box is a telescopic structure.

[0011] Furthermore, the inner ring assembly is provided with a set of first slots, and the first insert plate is vertically inserted into the first slots to separate the collection area and the classification area.

[0012] Furthermore, the outer ring of the inner ring assembly is provided with a set of slots for engaging the second insert plate, which is used to separate the classification and holding areas.

[0013] Furthermore, the connection adjustment mechanism includes a locking tooth, an adjusting push rod, a fixed protrusion, and a locking push rod; the adjusting push rod is connected to the fixed protrusion, the adjusting push rod is slidably connected to the locking tooth, and the locking push rod is connected to the adjusting push rod.

[0014] Furthermore, the sorting and holding box is correspondingly disposed in the second slot, and both ends are disposed in the connecting adjustment mechanism.

[0015] Furthermore, through holes are provided on both sides of the sorting and holding box, the through holes are aligned with the fixed protrusions, and the two sides of the sorting and holding box are provided in the retaining teeth.

[0016] Furthermore, the classification and holding box includes an outer box and an inner box, with the outer box fitted over the outside of the inner box.

[0017] Furthermore, the diameter of the collection and holding area is 40-60cm, and the ring width of the classification and holding area is 40-100cm.

[0018] Compared with existing technologies, the advantages and effects of this application are as follows:

[0019] 1. This application relates to a fish species sorting device suitable for field surveys. The design of the handle and casters makes the entire device easy to move and adaptable to the complex and ever-changing outdoor working environment. In particular, for field survey tasks that require frequent changes of work location, it greatly improves the flexibility and efficiency of the work.

[0020] 2. This application relates to a fish species sorting device suitable for field surveys. The device forms a collection and holding area inside the inner ring component and a classification and holding area outside. This design makes reasonable use of limited space, ensuring both centralized storage of samples and facilitating subsequent classification and processing.

[0021] 3. This application relates to a fish species sorting device suitable for field surveys. The existence of a connecting adjustment mechanism allows the device to be flexibly adjusted according to actual needs. Different areas are separated by a first insert plate and a second insert plate. The position of the sorting and holding box is precisely controlled by adjusting push rods, fixed protrusions and other components. The sorting and holding box adopts a telescopic structure and is divided into an outer box and an inner box. The volume can be adjusted according to the sample size to meet the processing requirements of samples of different sizes and quantities.

[0022] 4. This application relates to a fish species sorting device suitable for field surveys. By using a locking push rod and a locking tooth in combination, it ensures that the sorting container can be stably held in a predetermined position when sorting samples, while simplifying the operation process and enabling the sample sorting work to be completed quickly and accurately even in outdoor environments.
