Description

Technical Field

[0001] This utility model relates to aquatic fishing, specifically to a semi-automatic fishing weighing system and a semi-automatic fishing method. Background Technology

[0002] In fisheries production, the transfer of fish from ponds to transport trucks directly impacts operational efficiency, fish survival rates, and production costs. Traditional transport methods, relying primarily on manual labor or simple machinery, suffer from the following core technological shortcomings:

[0003] I. Heavy reliance on manual labor and low work efficiency

[0004] Traditional operations require a large workforce for manual loading and transporting, with a single transport volume typically less than 100 kg, making it difficult to meet the high-efficiency loading requirements of large-scale aquaculture. Taking a fishpond with a yield of 5,000 kg per mu as an example, traditional manual handling would take several days to complete the transfer, while equipment with low mechanization levels cannot meet the bulk harvesting needs of modern fisheries.

[0005] II. High fish injury rate leads to significant economic losses.

[0006] 1. Damage from dry handling: Fish will show signs of oxygen deficiency if they are out of water for more than 5 minutes by manual carrying, pushing, or other methods, which reduces the market value of high-value fish species (such as bass and mandarin fish).

[0007] 2. Damage from mechanical handling: When water is transported by equipment such as water pumps, excessively fast water flow can cause squeezing injuries to the fish, which seriously affects the quality of the marketable fish.

[0008] III. Insufficient equipment adaptability and limited promotion

[0009] 1. Poor terrain adaptability: Traditional conveyor belt equipment is prone to slipping on muddy pond edges, and the water pump system is sensitive to water level fluctuations. When the water level drops, the equipment position needs to be adjusted frequently, and small and medium-sized farmers need to invest additional costs for equipment modification.

[0010] 2. High cost: The purchase and maintenance costs of fully automated conveying equipment are high, far exceeding the affordability of small and medium-sized farmers.

[0011] IV. Environmental safety risks and operational hazards

[0012] 1. Personnel safety issues: When working in rainy weather or on wet and slippery surfaces, accidents of people slipping and falling while carrying materials often occur.

[0013] In summary, although existing technical solutions attempt to improve efficiency through mechanization, they generally suffer from problems such as low automation, high overall cost, and limited applicability to specific scenarios. There is an urgent need for a semi-automatic transfer system that is efficient, low-damage, and highly adaptable to various environments. Utility Model Content

[0021] Furthermore, the first horizontal bracket is equipped with two parallel limiting strips that are close to the shore and the fishpond respectively, which limit the front and rear positions of the fish transport frame on the first horizontal bracket.

[0022] The first pushing mechanism is located on the side away from the tilting slide plate at the top of the first sliding bracket. The first pushing mechanism includes a first T-shaped push rod that moves along the direction of the limiting strip. The first T-shaped push rod pushes the fish transport frame containing fish, which has slid to the top of the fish loading track, to the tilting slide plate.

[0023] Furthermore, the second pushing mechanism is located on the side of the weighing platform away from the feeding rail. The second pushing mechanism includes a second T-shaped push rod that moves along the vertical side. The second T-shaped push rod pushes the empty fish frame on the weighing platform to the second sliding bracket at the top of the feeding rail.

[0024] Furthermore, the weighing platform includes a lower base, a weighing device, and an upper floating plate. The lower base is fixedly connected to the second sliding bracket. Both the lower base and the upper floating plate are provided with tilting openings that coincide in the vertical direction.

[0028] Furthermore, the top of the fish transport frame is equipped with an elastic pull rope fishing net, one end of which is fixedly connected to one side of the fish transport frame, and the other end of which is detachably connected to a hook on the other side of the fish transport frame.

[0029] Furthermore, the length and width of the fish pouring opening are smaller than the length and width of the pouring opening, the space inside the fish transport frame is funnel-shaped with a wider top and a narrower bottom, and the fish transport frame is equipped with drainage holes.

[0030] Furthermore, the manual platform is located on the side of the inclined slide and weighing platform closest to the fishpond, and the side of the manual platform closest to the fishpond is equipped with a fall prevention railing.

[0031] The advantages of this utility model are:

[0032] This semi-automatic fish weighing system has many advantages, effectively improving the efficiency of fish transportation in fisheries production, reducing costs, and minimizing fish damage, as detailed below:

[0033] 1) The system automatically moves fish transport frames back and forth on the tracks using first and second sliding brackets, achieving mechanized fish transfer, reducing manual intervention, and enabling continuous operation. Compared to traditional manual loading and handling, it allows for a larger single transport capacity, significantly improving handling efficiency and meeting the requirements for high-efficiency loading. The various components of this system are closely integrated; the first and second pushing mechanisms enable the automatic pushing of fish transport frames between different tracks and platforms, reducing the time and labor intensity of manual handling.

[0034] 2) The space inside the fish transport frame is funnel-shaped, wider at the top and narrower at the bottom. The bottom plate is equipped with a fish-pouring opening and a gravity-operated flap, allowing the fish to fall naturally during unloading, reducing the squeezing and collision of the fish caused by manual operation.

[0035] 3) The system ensures a certain level of moisture within the fish transport frame during transport, preventing prolonged periods of oxygen deprivation and reducing fish injury rates. An elastic rope net is installed at the top of the fish transport frame to prevent fish from escaping while climbing the track, avoiding damage such as scale loss due to vigorous activity.

[0036] 4) The fish transport pipeline is connected to the fish tanks via flexible hoses. The hoses can be moved flexibly to connect to different fish tanks as needed, so as to realize the classified transport of fish and adapt to the transfer needs of different fish species.

[0037] 5) This system has a high degree of automation, which reduces the reliance on a large workforce. Only a small number of people are needed to perform auxiliary operations (such as assisting in pushing the fish transport frame, replacing the fish box connected by the hose, etc.), which significantly reduces labor costs.

[0038] 6) The transfer weighing platform integrates a tilting slide, a weighing platform, and a pushing mechanism, achieving seamless connection between weighing and transfer, and ensuring the continuity and accuracy of the transfer process. Attached Figure Description

[0052] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0053] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0054] This utility model provides a semi-automatic fishing weighing system, which is used to transfer fish in a fishpond 1 to a fish transport vehicle 600 parked on the bank 2. The fish transport vehicle 600 is loaded with at least one fish box. The semi-automatic fishing weighing system includes a fish loading track 100, a transfer weighing platform 200, a frame delivery track 300, and a fish conveying pipe 400. The transfer weighing platform 200 is set on the bank 2. The bottoms of the fish loading track 100 and the frame delivery track 300 are both located in the fishpond 1, and the tops of the fish loading track 100 and the frame delivery track 300 are respectively connected to the two ends of the transfer weighing platform 200.

[0055] The first sliding bracket 110 and the second sliding bracket 310 are slidably provided on the fish loading track 100 and the frame feeding track 300, respectively. The first sliding bracket 110 and the second sliding bracket 310 are both equipped with sliding drivers. The first sliding bracket 110 and the second sliding bracket 310 are respectively equipped with a first horizontal bracket 111 and a second horizontal bracket.

[0056] The first and second horizontal brackets are used to lay the fish transport frame 500 flat. The bottom plate of the fish transport frame 500 is provided with a fish-pouring opening 512, and a gravity flap 510 is hinged to one side of the fish-pouring opening 512 (e.g., Figure 12 When the gravity flap 510 is unsupported at the bottom, it naturally droops under the action of gravity to open the fish-falling opening 512, and the fish in the fish transport frame 500 fall naturally.

[0057] like Figure 4 and 6 As shown, the transfer weighing platform 200 includes a manual platform (not shown in the figure), an inclined slide plate 210 located on one side of the manual platform, and a weighing platform 220 (as shown in the figure). Figure 6-7 The high side of the inclined slide plate 210 is close to the fish-raising track 100, and the low side of the inclined slide plate 210 is connected to the weighing platform 220. The weighing platform is provided with a vertically penetrating pouring opening 222. A baffle is provided in the pouring opening 222. The baffle is driven by a baffle driving mechanism to open or close the pouring opening 222.

[0058] The transfer weighing platform 200 is also provided with a first pushing mechanism 211 and a second pushing mechanism 221. The first pushing mechanism 211 is used to push the fish transport frame 500 on the first sliding bracket 110 at the top of the fish loading track 100 to the inclined slide plate 210. The second pushing mechanism 221 is used to push the fish transport frame 500 on the weighing platform to the second sliding bracket at the top of the frame delivery track 300.

[0059] like Figure 5As shown, the fish conveying pipe 400 is fixed directly below the tilting port 222 of the weighing platform 220. The fish conveying pipe 400 is equipped with a horn-shaped collection port 410 and a flexible hose 420 connected to the bottom of the horn-shaped collection port 410. The bottom of the flexible hose 420 can be moved to connect to any fish box 610 of the fish transport vehicle 600 as needed.

[0060] In an optional embodiment, the first horizontal bracket 111 and the second horizontal bracket are equipped with spring switches, which are connected to a sliding actuator. The sliding actuator is a motor-driven rack and pinion mechanism. The spring switches trigger the motor to start and stop, enabling the first sliding bracket 110 and the second sliding bracket 310 to automatically reciprocate on the fish loading track 100 and the frame delivery track 300. After the fish frame 500 is placed on the first horizontal bracket 111 or the second horizontal bracket, the spring switches are pressed to detect whether a fish frame 500 is placed on the first horizontal bracket 111 or the second horizontal bracket.

[0061] In an optional embodiment, the first horizontal bracket 111 of the first sliding bracket 110 is provided with two parallel limiting strips 112 that are respectively close to the bank 2 and the fishpond 1, such as... Figure 3 As shown, the front and rear positions of the fish transport frame 500 on the first horizontal bracket are limited by the limiting strip, so that the first pushing mechanism 211 can accurately push the fish transport frame 500 to the inclined slide plate 210.

[0062] The first pushing mechanism 211 is located on the side of the top of the first sliding bracket 110 away from the inclined slide plate 210. The first pushing mechanism 211 includes a first T-shaped push rod that moves along the direction of the limiting strip 112. The first T-shaped push rod pushes the fish transport frame 500, which has slid to the top of the fish loading track 100 and is loaded with fish, to the inclined slide plate 210 (e.g., Figure 6 (Arrow direction).

[0063] The second pushing mechanism 221 is located on the side of the weighing platform 220 away from the frame delivery track 300. The second pushing mechanism 221 includes a second T-shaped push rod that moves along the vertical side. The second T-shaped push rod pushes the empty fish transport frame 500 on the weighing platform 220 onto the second sliding bracket at the top of the frame delivery track 300 (e.g., Figure 7 (Arrow direction).

[0064] The weighing platform includes a lower base, a weighing device, and an upper floating plate. The lower base is fixedly connected to a second sliding bracket. Both the lower base and the upper floating plate have tilting openings 222 that coincide in the vertical direction. Multiple weighing devices are positioned between the lower base and the upper floating plate, located on either side of the tilting openings 222. After the fish transport frame 500 slides onto the upper floating plate, its weight is applied to the upper floating plate and transferred to the weighing device, which measures the total weight of the fish transport frame 500 and its contents. The structure of the weighing platform is similar to that of a weighbridge in the prior art and will not be described in detail here.

[0065] In an alternative embodiment, such as Figure 8-9 As shown, the baffle is a T-shaped rod 201 that can flip up and down within the tilting opening 222. One end of the T-shaped rod 201 is rotatably connected to the lower base. The baffle driving mechanism is a drive motor, which is connected to one end of the T-shaped rod 201. The drive motor drives the baffle to flip up and down, thereby opening or closing the tilting opening 222 of the weighing platform. When the fish transport frame 500 is weighed, the T-shaped rod 201 flips upward to abut against the gravity flap 510 of the fish transport frame 500, preventing the gravity flap 510 from sagging and ensuring that the fish-pouring opening 512 of the fish transport frame 500 is in a closed state. After weighing is completed, the T-shaped rod 201 rotates downward, and the bottom of the gravity flap 510, without support, naturally droops under the action of gravity, opening the fish-pouring opening 512.

[0066] In another alternative embodiment, such as Figure 10-11 As shown, the lower base is fixed with a horizontal track, and the baffle is a slide plate 202 horizontally installed on the horizontal track. The top surface of the slide plate 202 is not higher than the upper floating plate. The baffle drive mechanism includes a drive motor and drive rollers, with the drive rollers engaging in rolling friction with the slide plate. The drive motor drives the drive rollers to rotate, which in turn drives the baffle to slide outward along the horizontal track, thereby opening or closing the tilting opening 222 of the weighing platform. The use of rollers to drive the slide plate to slide on the track is a common track drive mechanism in the industry and will not be elaborated upon here.

[0067] In an optional embodiment, the top of the fish transport frame 500 is provided with an elastic rope fishing net (not shown in the figure). One end of the elastic rope fishing net is fixedly connected to one side of the fish transport frame 500, and the other end of the elastic rope fishing net is detachably connected to a hook on the other side of the fish transport frame 500 to prevent the fish from jumping around and escaping from the fish transport frame during the track climbing process.

[0068] It should be noted that during fish loading, the staff in the fishpond will ensure that the fish transport frame 500 contains a certain amount of water. The length and width of the fish pouring opening 512 are smaller than those of the tilting opening 222, allowing the bottom of the fish transport frame 500 to be placed completely flat on the floating plate for weighing. Simultaneously, when the tilting opening 222 of the weighing platform is opened, the gravity flap 510 of the fish pouring opening 512 is unobstructed and naturally hangs down to open the fish pouring opening 512 of the bottom plate of the fish transport frame. During the weighing process, a baffle plate holds the gravity flap 510 in place to keep the fish pouring opening 512 of the bottom plate of the fish transport frame closed.

[0069] Preferably, the space inside the fish transport frame is funnel-shaped, wider at the top and narrower at the bottom, such as... Figure 12 As shown, after the gravity flap 510 hangs down and opens the fish-pouring opening 512, all the fish in the fish transport frame can be discharged.

[0070] The bottom plate, gravity flap 510, and / or side walls of the fish transport frame are provided with drainage holes, so that the water inside the fish transport frame 500 on the first sliding bracket 110 automatically flows out during the climbing process. When the fish transport frame 500 climbs to the top of the first sliding bracket 110, the water inside the fish transport frame 500 is basically completely drained, so that the weight of the water is eliminated as much as possible during weighing. In practical applications, the fish transport frame 500 with the appropriate number / diameter of drainage holes 511 can be selected in advance according to factors such as the climbing speed and climbing distance of the fish transport frame 500.

[0071] In an optional embodiment, the manual platform is positioned on the side of the inclined slide 210 and the weighing platform closest to the fishpond 1. The side of the manual platform closest to the fishpond 1 is equipped with a fall arrest railing to prevent personnel from falling. Transferring the weighing platform requires an operator whose responsibilities are: 1) assisting in pushing the fish transport frame 500 from the inclined slide to the designated position on the weighing platform; 2) connecting the end of the flexible hose to the corresponding fish box according to the type of fish (the flexible hose can be quickly replaced to connect to different fish boxes).

[0072] A control switch is set on the manual platform and connected to the second pushing mechanism. After the fish unloading work is completed, press the control switch and the second pushing mechanism will push the fish transport frame 500 to the second horizontal bracket at the top of the frame delivery track.

[0073] The method of fishing using the above-mentioned semi-automatic fishing weighing system includes the following steps:

[0074] S1. In the fishpond 1, the fish transport frame 500 containing silver carp is placed flat on the first horizontal bracket 111 of the first sliding bracket 110 of the fish loading track 100. The gravity flap 510 is in contact with the first horizontal bracket 111 to keep the bottom of the fish transport frame 500 closed.

[0075] S2. The sliding drive of the first sliding bracket drives the first sliding bracket 110 to climb up the upper fish track to the top of the upper fish track 100.

[0076] S3, the first pushing mechanism 211 pushes the fish transport frame 500 on the first sliding bracket 110 to the tilting slide plate 210.

[0077] S4. The fish transport frame 500 slides on the inclined slide plate 210 to the weighing platform 220 (manual assistance can be provided at this time). At this time, the gravity flap 510 and the rotating side of the fish transport frame 500 are close to the second pushing mechanism, which facilitates the automatic closing of the gravity flap 510 later. In addition, the baffle provides bottom support for the gravity flap 510 to prevent it from sagging.

[0078] S5, the fish transport frame 500 is weighed on the weighing platform 220.

[0079] S6. Drive the baffle to flip downward or move backward to release the support of the gravity flap 510. The gravity flap 510 hangs down naturally under the action of gravity and opens the fish pouring opening 512. The fish in the fish transport frame fall into the fish transport pipe 400 directly below through the fish pouring opening 512 and the pouring outlet 222. The fish are then transported to the fish box of the corresponding fish species through the hose 420 at the bottom of the fish transport pipe 400.

[0080] S7. Subsequently, the second pushing mechanism pushes the empty fish transport frame on the weighing platform onto the second horizontal bracket 310 of the second sliding bracket. During the movement of the empty fish transport frame towards the second sliding bracket, the gravity flap 510 cooperates with the weighing platform 220 and the second horizontal bracket to achieve closure. Then the baffle returns to its position, waiting for the next fish transport frame to be unloaded.

[0081] S8. The sliding drive of the second sliding bracket drives the second sliding bracket to slide downward into the fishpond along the frame feeding track;

[0082] S9. Repeat steps S1-S8.
