Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a shrimp grading, screening and conveying device. Background Technology

[0002] As a popular aquatic product, shrimp processing demands increasingly higher standards for efficiency, hygiene, and standardization. In shrimp processing lines, conveying, cleaning, and grading by specifications are crucial pre-processing steps that directly impact the quality and economic value of subsequent products.

[0003] To improve production efficiency and grading accuracy, automated grading equipment has gradually replaced traditional manual sorting. In existing technologies, an "electronic weighing-electric control execution" solution is typically used to achieve automated grading. Specifically, this type of equipment uses high-precision electronic sensors to weigh each shrimp on the conveyor belt, then transmits the weight signal to a central controller. After determining the shrimp's weight grade, the controller issues a command to drive a pneumatic or electric actuator to move the shrimp into the corresponding collection channel.

[0004] While the aforementioned solutions achieve accurate grading, their structure is relatively complex. The entire system heavily relies on the coordinated operation of electronic weighing sensors, a central controller, and multiple electrically or pneumatically controlled actuators. This complex electronic control system not only significantly increases the manufacturing cost and maintenance difficulty of the equipment, but also results in a relatively high failure rate of electronic components in the humid and corrosive environment of aquatic product processing, thus affecting the stability and reliability of the entire production line. Therefore, developing an automated grading device with a simpler structure, lower cost, and more reliable operation has become an urgent technical problem to be solved in this field.

[0005] Therefore, this utility model proposes a shrimp grading, screening, and conveying device to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a shrimp grading and screening conveying device, which aims to improve the problems of existing shrimp grading and screening conveying devices that usually rely on electronic sensing and electronic control systems to achieve grading, resulting in complex structure, high production cost, and low reliability in humid environments.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A shrimp grading and screening conveying device includes: a base, a slide rail, a screening rail; and a screening trough.

[0009] The screening tank includes a tank with an eccentric rotating shaft. This structure allows the overall center of gravity to shift when the weight of the shrimp in the tank exceeds a preset value, thus enabling it to automatically flip downwards around the eccentric rotating shaft.

[0010] Furthermore, the slide rail is movably disposed above the base, the screening rail is fixed on the base and located below the slide rail, and the screening slot is rotatably connected to the slide rail so that when it moves above the corresponding screening rail, it can perform a flipping action and unload the shrimp into it.

[0011] Preferably, the device further includes a support rod fixed to the base, a second rotating rod fixedly connected to the inner side of the support rod, a roller rotatably connected to the second rotating rod, and the slide rail slidably supported on the roller to achieve smooth movement.

[0012] Preferably, a fixed block is fixedly connected to the slide rail, a movable block is rotatably connected to the fixed block, and the screening groove is fixedly connected to the movable block, thereby forming a rotatable connection structure for installing the screening groove.

[0013] Preferably, the device further includes a chute, the discharge end of which is used to convey shrimp into the screening tank.

[0014] Preferably, a rolling brush is provided in the chute, the rolling brush is fixedly connected to a first rotating rod, and the first rotating rod is rotatably connected to the chute.

[0015] Preferably, the rolling brush includes bristles made of extremely fine soft bristles for cleaning the surface of the shrimp during transport.

[0016] Preferably, the device further includes a conveyor platform, which abuts against the feed end of the chute for smoothly introducing shrimp.

[0017] Preferably, the screening rail includes at least two collection channels arranged along the moving direction of the rail for receiving shrimp of different weights and sizes.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by setting a screening groove with an eccentric rotating shaft, it can automatically trigger a flipping action according to the weight of the shrimp inside, which solves the problem that existing grading devices usually rely on complex sensing and electronic control systems, resulting in complex structures and high costs. It achieves the technical effect of simplifying the equipment structure, reducing manufacturing costs and maintenance difficulty, and realizing reliable automated mechanical grading.

[0020] 2. In this utility model, by integrating the cleaning trough with the rolling brush with the subsequent weight grading mechanism, the cleaning and grading functions are seamlessly connected. This solves the problem that in the prior art, cleaning and grading need to be completed by separation equipment, resulting in a large footprint, cumbersome process and low efficiency. It achieves the technical effect of compact equipment structure and continuous and efficient processing flow. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a shrimp grading and screening conveying device, which aims to solve the problem that existing shrimp processing devices have single functions, complex grading structures, and high costs, and lack a device that can compactly integrate flexible cleaning and passive weight grading functions.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, the shrimp grading and screening conveying device includes a base 5, which serves as the installation base for the entire device. A screening rail 13 is fixedly connected to the top of the base 5. A slide rail 12 is movably arranged above the screening rail 13. A screening trough 11 for weighing and grading shrimp is rotatably connected to the slide rail 12. The screening trough 11 moves above the screening rail 13 as the slide rail 12 moves.

[0031] The screening tank 11 enables automatic grading and unloading of shrimp based on their weight. Its specific structure is as follows: The screening tank 11 includes a tank body for carrying shrimp and an eccentrically positioned rotating shaft. This rotating shaft rotatably connects the tank body to the slide rail 12. When unloaded, the center of gravity of the screening tank 11 is stably located on one side of the rotating shaft, thus maintaining its initial position for receiving shrimp. When the weight of the shrimp entering the tank reaches a preset value, the weight of the shrimp changes the overall center of gravity of the screening tank 11. When the overall center of gravity crosses the vertical line of the rotating shaft, the screening tank 11 generates a flipping torque and automatically flips downwards. When the slide rail 12 moves above the corresponding screening rail 13, the flipped screening tank 11 accurately unloads the shrimp into the lower screening rail 13. By setting different flipping weight thresholds for different screening tanks 11, automated grading of shrimp of different sizes can be achieved.

[0032] To ensure stable movement of the slide rail 12 above the base 5 and to provide a reliable rotational connection for the screening tank 11, the structure of this shrimp grading and screening conveying device further includes a supporting moving mechanism and a rotating connection mechanism. Please refer to [reference needed]. Figure 1 , Figure 3 and Figure 4 The following is a detailed description of the support and connection structure:

[0033] Multiple support rods 6, serving as a support frame, are fixedly connected to the top of the base 5. A second rotating rod 8 is horizontally fixedly connected to the inner wall of each support rod 6. Rollers 7 are rotatably mounted on the second rotating rod 8 through their central shaft holes, thus forming a set of rolling support components. The bottom of the slide rail 12 is provided with a flat and smooth track surface, which is slidably supported on the top of the multiple rollers 7. When the slide rail 12 needs to be moved, it can move smoothly with low resistance along the straight path defined by the multiple rollers 7 under the rolling action of the rollers 7.

[0034] Meanwhile, in order to reliably rotatably mount the screening tank 11 on the slide rail 12, multiple fixed blocks 9 are fixedly connected at intervals on the outer side wall of the slide rail 12. Each fixed block 9 is rotatably connected to a movable block 10 via a pin. Each screening tank 11 is rigidly fixedly connected to the corresponding movable block 10. Through the connection chain of "slide rail 12-fixed block 9-movable block 10-screening tank 11", it is ensured that the screening tank 11 can move with the slide rail 12 as a mounting component. At the same time, through the rotating pair formed by the fixed block 9 and the movable block 10, the necessary degree of freedom is provided for the screening tank 11 to perform its eccentric weight sensing flipping action, ensuring the smooth realization of the grading action.

[0035] Based on the above embodiments, the feeding end of this utility model also integrates a cleaning and conveying mechanism to pre-clean the shrimp before they enter the grading process. This mechanism includes the following technical solutions:

[0036] As a preferred implementation method, please refer to Figure 1 and Figure 2 The device also includes a chute 1. The discharge end of the chute 1 is configured to accurately guide the shrimp into the opening of the moving screening tank 11. The feed end of the chute 1 abuts against the conveyor table 4. The conveyor table 4 serves as a smooth transition platform to receive and guide the shrimp to slide smoothly into the chute 1 to begin the subsequent cleaning and grading process.

[0037] Multiple rolling brushes 3 are provided on the inner wall of the chute 1. Specifically, multiple first rotating rods 2 are rotatably mounted between the two side walls of the chute 1. Each first rotating rod 2 is fixedly equipped with one or more sets of rolling brushes 3. The bristles of these rolling brushes 3 are made of extremely fine and soft material to ensure that when they roll and come into contact with the shrimp, they can effectively remove impurities and mucus from the surface without causing any damage to the shrimp meat, thus ensuring the quality of the product.

[0038] For further optimization of tiered collection, please refer to... Figure 1 and Figure 3 The screening track 13 is specifically composed of at least two or more parallel collection channels. These collection channels are arranged sequentially along the moving direction of the slide rail 12. Each collection channel corresponds to a certain weight of shrimp. When the screening trough 11 carrying a specific weight of shrimp moves above the corresponding collection channel, it will trigger a flipping action, thereby accurately classifying shrimp of different sizes into their respective collection channels and achieving efficient classification.

[0039] Working principle: When in use, the shrimp is first placed on the conveyor 4 and then smoothly slides into the chute 1. As it slides down the chute 1, the shrimp rolls over multiple rolling brushes 3 fixed on the first rotating rod 2. The rolling brushes 3 use extremely fine soft bristles to gently brush the surface of the shrimp without damaging it, thus completing the initial cleaning process.

[0040] The cleaned shrimp slide out from the end of the chute 1 and fall accurately into a screening trough 11 supported by a slide rail 12. At this time, the external drive device drives the slide rail 12 to move smoothly on the rolling support system composed of the support rod 6, the second rotating rod 8, and the roller 7. The screening trough 11 is rotatably connected to the slide rail 12 through a combination structure of the fixed block 9 and the movable block 10, and moves forward with it. Since the screening trough 11 has a structure design with an eccentric rotating shaft, the torque required for its flipping is preset. When the slide rail 12 carrying the screening trough 11 containing shrimp moves above the screening rail 13 corresponding to the weight grade of the shrimp, the weight of the shrimp causes the overall center of gravity of the screening trough 11 to cross the critical point, thereby automatically flipping downward. The flipped screening trough 11 accurately unloads the shrimp into a specific channel of the screening rail 13 below, while the shrimp whose weight has not reached the current flipping threshold will continue to move with the screening trough 11 to the next grading station. Through this cycle, the continuous automated grading of shrimp of different sizes is finally realized.
