Description

Technical Field

[0001] This invention specifically relates to a shrimp separating device. Background Technology

[0002] Avoiding injury to crayfish during automated sorting is a significant challenge. Live crayfish often suffer shell or muscle damage, or even death, due to external forces during mechanical processing. Most existing sorting equipment uses high-speed conveying and mechanical gripping, which can cause crayfish to be squeezed or impacted during high-speed movement. Live crayfish have relatively fragile external structures, especially during handling, making them easily injured or even killed by external forces, directly affecting their market value.

[0003] Currently, some automatic sorting devices use differential speed, airflow, or vibration technology, aiming to separate lobsters through belt speed differences, air blowing, or vibration.

[0004] 1. Shortcomings of differential sorting devices Working principle and limitations: The differential speed sorting device separates lobsters through the differential speed action of the belt conveyor. The speed difference of the belt conveyor causes the lobsters to undergo relative displacement under different belt speeds, thereby achieving separation.

[0005] Problems: (1) Large equipment size: Differential sorting devices require a large space to accommodate the belt conveyor and related power system, which increases the size of the equipment, the floor space occupied, and the difficulty of installation. (2) Low separation degree: When lobsters are piled up, the density between lobsters is high, and differential sorting is often difficult to separate them effectively. Due to the irregular body shape and high activity of lobsters, the differential speed of the belt conveyor may not be able to accurately handle the separation of each individual, resulting in poor separation effect, and some lobsters may still be piled up together. (3) Poor adaptability: When the lobsters have large differences in body size or high activity, the separation effect of the differential sorting device will be affected, and it will be unable to meet more complex sorting requirements (such as accurate differentiation of size, weight, type, etc.).

[0006] 2. Shortcomings of airflow technology Working principle and limitations: Airflow sorting technology relies on an air compressor to generate high-speed airflow, which is used to separate lobsters. This method is typically used for rapidly processing large quantities of products and is commonly used in the sorting of fruits, vegetables, and seafood.

[0007] Problems: (1) Surface complexity: Lobsters have a complex appearance, with hard shells, tentacles, and claws, and their surface structure is irregular, making it difficult for airflow to accurately target each lobster. The airflow may not only fail to separate them effectively, but may also cause some lobsters to be blown out of the sorting area or piled up together. (2) Limited air jets: The number and location of air jets in the airflow system are usually limited, which cannot cope with the diversity and complexity of lobsters. Due to the activity of lobsters, it is difficult for the airflow to be sprayed evenly, which may cause some lobsters to be sprayed to the wrong area, or even blow live lobsters out of the sorting range, causing damage. (3) Poor separation effect and high damage rate: Since lobsters are live, their sensitive shells and body parts are very easily impacted by high-speed airflow, which may cause mechanical damage, scratches on the body surface, or limb loss, resulting in a high damage rate. In addition, airflow sorting is also difficult to achieve high-precision classification, resulting in poor sorting effect.

[0008] 3. Shortcomings of the vibration scheme Working principle and limitations: Vibration sorting schemes use industrially common direct vibration equipment (such as vibrating screens) to separate lobsters through vibration. This technology is commonly used for sorting granular or lumpy materials.

[0009] Problems: (1) Poor performance: The vibration frequency and amplitude of the direct vibration scheme are mainly suitable for processing loose and relatively uniform objects, but lobsters vary greatly in size and have irregular shapes, making it difficult for direct vibration to achieve precise separation. Lobsters often do not distribute themselves as expected during vibration, resulting in low sorting efficiency. (2) Only thinning effect: Although vibration can slightly improve the lobster accumulation, it cannot effectively achieve fine sorting. In the dense accumulation of lobsters, vibration can only play a "thinning" role and cannot effectively achieve separation. This means that a large number of lobsters are still piled together, and the sorting effect is very limited. (3) Lack of precise analysis: Vibration technology cannot accurately identify and analyze the characteristics of each lobster, such as body shape, posture, and species, resulting in the inability to achieve personalized sorting. For example, lobsters of different body shapes may be "stirred" together at the same time, making it impossible to accurately identify their type or species.

[0010] While these existing solutions may be effective under certain specific conditions, none of them can fully address several key issues in the crayfish sorting process: (1) High efficiency: Due to factors such as irregular body shape, severe accumulation and high activity of lobsters, existing sorting methods are difficult to work effectively in high-density and high-speed production environments, resulting in low sorting efficiency.

[0011] (2) Non-destructive: The external structure of live lobsters is complex, and airflow and vibration can easily cause damage. Differential devices cannot avoid pressure and friction on lobsters, resulting in a high damage rate.

[0012] (3) Accuracy: Existing technologies have failed to achieve accurate sorting. Airflow and vibration technologies lack precise control over individual components, while the separation accuracy of differential devices is insufficient in complex scenarios.

[0013] Therefore, these methods still have significant shortcomings when it comes to sorting lobsters, which is why manual separation still dominates the market. This forces farmers to accept extremely low sorting efficiency and high costs. Summary of the Invention

[0014] The purpose of this invention is to provide a crayfish sorting device that solves the shortcomings of low efficiency and poor accuracy in the sorting of crayfish in the prior art.

[0015] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A shrimp separation device includes a fixed frame, a turntable, and a separation unit. The turntable is fixed on the fixed frame, and the separation unit is fixed on the turntable. The rotation of the turntable drives the separation unit to move to different positions to remove shrimp from the separation unit in batches, thereby achieving shrimp separation.

[0016] In this invention, the separation unit includes a shell, a first guide member, and a second guide member; the first guide member and the second guide member are disposed inside the shell, dividing the shell into a first chamber and a second chamber, the first chamber and the second chamber respectively accommodating different shrimp, the first guide member being used to guide the shrimp in the first chamber out of the separation unit, and the second guide member being used to guide the shrimp in the second chamber out of the separation unit.

[0017] Furthermore, the first chamber is located below the second chamber.

[0018] Furthermore, the first chamber can only hold one crayfish. This design allows for precise separation of a single crayfish.

[0019] In this invention, one end of the first guide member is connected to the bottom of the housing, and the other end is fixed to the top edge of one side wall of the housing; one end of the second guide member is fixed to the top edge of the other side wall of the housing and is inclined inward into the housing, and the other end is directly opposite the first guide member, forming the entrance and exit of the first chamber with the first guide member.

[0020] The present invention can be improved in the following way: the first guide member is a guide groove, and the second guide member is a baffle.

[0021] Furthermore, the first guide extends outward from the shell and protrudes from the shell, and the first guide has two guide grooves. With this configuration, one guide groove of the first guide is used for the crayfish in the first chamber of the separation unit to exit the separation unit, and the other guide groove is used to block and guide the crayfish in the second chamber of the adjacent separation unit after they have left the separation unit by the second guide, so as to prevent the crayfish from leaving the separation unit too early before reaching the separation position and falling into the designated position, which would damage the crayfish and reduce the screening efficiency.

[0022] Furthermore, the angle between the first guide member and the horizontal plane is 0°-90°; the angle between the second guide member and the horizontal plane is 0°-90°.

[0023] Preferably, the first guide member makes an angle of 45 degrees with the horizontal plane. o -70 o The second guide member makes an angle of 15 degrees with the horizontal plane. o -45 o The angle between the second guide and the horizontal plane directly affects the time it takes for crayfish to leave the separation unit in the second chamber as well as the time it takes for crayfish to leave the separation unit in the first chamber. The angle between the second guide and the horizontal plane directly affects the time it takes for the crayfish to be guided again after leaving the separation unit in the second chamber. Through experiments, the above-mentioned angle ensures that the crayfish leave the separation unit at the right time, which facilitates separation and collection while reducing damage to the crayfish.

[0024] In this invention, the shell is an open cylindrical structure, with both side walls arranged radially along the turntable. This arrangement facilitates the fixed connection between the two separation units and provides enhanced stability.

[0025] Furthermore, the included angle between the two side walls of the cylinder is 0-90 degrees. o Based on actual working conditions, the size of the final assembled separation turntable can be controlled by adjusting the curvature of separation unit 1, thereby achieving the goal of flexibly adjusting the equipment size to realize different sorting efficiencies.

[0026] This invention also includes a drive unit, which is connected to the turntable via a transmission connection. The drive unit provides power to rotate the turntable.

[0027] The present invention also includes a feeding conveyor belt, the discharge port of which is located above the top of the turntable.

[0028] Furthermore, it also includes a feeding conveyor belt, the feed inlet of which is positioned directly opposite the turntable.

[0029] This invention also includes a re-sorting and recycling mechanism, which is located on one side of the turntable and is used to collect the crayfish separated from the second chamber. The re-sorting and recycling mechanism collects the crayfish separated from the second chamber and then separates and screens them again via a feeding conveyor belt.

[0030] The present invention has the following beneficial effects: (1) The shrimp sorting device of the present invention is provided with a separation unit and a turntable. The turntable drives the separation unit to rotate, and the shrimp in the separation unit are moved out of the separation unit in batches, so as to achieve efficient and high-precision sorting of crayfish.

[0031] (2) The crayfish sorting device of the present invention optimizes the structure of the separation unit, adjusts the time when the crayfish enters the crayfish sorting device and the timing when the crayfish is separated from the separation unit according to actual needs, reduces damage to the crayfish, realizes continuous sorting of crayfish, and improves the sorting efficiency of crayfish.

[0034] like Figure 1-7 The shrimp separating device shown includes a fixed frame 3, a turntable 2, a separating unit 1, and a drive unit.

[0035] Turntable 2 is fixed on the fixed frame 3, and multiple separation units 1 are fixed on turntable 2. The drive unit is connected to turntable 2 by transmission, which drives turntable 2 to rotate. The rotation of turntable 2 drives separation units 1 to move to different positions, so that the shrimp in separation units 1 are removed in batches and the shrimp are separated.

[0036] The separation unit 1 includes a housing 101, a first guide member 102, and a second guide member 103. The housing 101 is an open cylindrical structure, with its two side walls arranged radially along the turntable 2. This arrangement facilitates the fixed connection between the two separation units 1 and provides enhanced stability. The included angle between the two side walls of the cylinder is 0-90 degrees. o Based on actual working conditions, the size of the final assembled separation turntable 2 can be controlled by adjusting the curvature of the separation unit 1, thereby achieving the goal of flexibly adjusting the equipment size. In this embodiment, the included angle between the two side walls of the cylinder is 20°. o The first guide 102 and the second guide 103 are disposed inside the housing 101, dividing the housing 101 into a first chamber 104 and a second chamber 105. The first chamber 104 is located below the second chamber 105. The first chamber 104 and the second chamber 105 are used to accommodate different types of shrimp, and the volume of the first chamber 104 can only accommodate one crayfish. The first guide 102 is used to guide the shrimp in the first chamber 104 out of the separation unit 1, and the second guide 103 is used to guide the shrimp in the second chamber 105 out of the separation unit 1.

[0037] Specifically, one end of the first guide member 102 is connected to the bottom of the housing 101, and the other end is fixed to the top edge of one side wall of the housing 101. The angle α between the first guide member 102 and the horizontal plane is 0°-90°. One end of the second guide member 103 is fixed to the top edge of the other side wall of the housing 101 and is inclined inwards towards the housing 101. The angle β between the second guide member 103 and the horizontal plane is 0°-90°. The other end of the second guide member 103 faces the first guide member 102, forming the entrance and exit of the first chamber 104 together with the first guide member 102. In this embodiment, the first guide member 102 is a guide groove, and the second guide member 103 is a baffle. The first guide member 102 extends outwards from the housing 101 and protrudes from the housing 101. The first guide member 102 has two guide grooves. With this configuration, one guide groove of the first guide member 102 is used to guide the crayfish out of the first chamber 104 of the separation unit 1, and the other guide groove is used to block and guide the crayfish in the second chamber 105 of the adjacent separation unit 1 after they leave the separation unit 1 via the second guide member 103. This prevents the crayfish from leaving the separation unit 1 too early before reaching the separation position and falling, thus avoiding damage to the crayfish and reducing the screening efficiency.

[0038] The crayfish sorting device in this embodiment also includes a feeding conveyor belt 4, a discharging conveyor belt 5, and a re-sorting and recycling mechanism 6. The discharge port of the feeding conveyor belt 4 is located above the top of the turntable 2. After being conveyed and transferred by the feeding conveyor belt 4, the crayfish fall from the top of the turntable 2 into the separation unit 1 for sorting. The discharging conveyor belt 5 and the re-sorting and recycling mechanism 6 are respectively arranged on both sides of the turntable 2. The inlet of the discharging conveyor belt 5 is set directly opposite the turntable 2 and is used to receive single crayfish separated by the separation unit 1. The re-sorting and recycling mechanism 6 is used to receive multiple crayfish separated by the separation unit 1, and after recycling, they are transferred back to the feeding conveyor belt 4 for further separation. This cycle continues until the single crayfish is separated without damage.

[0039] like Figure 8-11 As shown, the shrimp-splitting process of the shrimp-splitting device of the present invention is as follows: 1. Feeding The crayfish are transferred to the top of the turntable 2 via the feeding conveyor belt 4. Due to gravity, the crayfish fall into each independent separation unit 1. Since the first chamber 104 can only hold one crayfish, any extra crayfish will slide into the second chamber 104 and be squeezed into the second chamber 105.

[0040] 2. First sorting As turntable 2 rotates clockwise, when independent separation unit 1 rotates to approximately the four o'clock position, due to gravity, and guided by the second guide 103 and the first guide 102, the crayfish slides out of separation unit 1 and enters the re-sorting and recycling mechanism 6, awaiting subsequent re-sorting. Individual crayfish in the first chamber 104 remain inside due to the blocking effect of the second guide 103 and continue rotating with turntable 2.

[0041] 3. Second sorting As the independent separation unit 1 moves to approximately the eight o'clock position, the single crayfish in the first chamber 104 will adhere tightly to the second guide 103 due to gravity, and gradually slide out of the first chamber 104 along the second guide 103. Then, it will slide down along the first guide 102 onto the unloading conveyor belt 5, completing the precise separation of the single crayfish.

[0042] As turntable 2 rotates, the 1-3 working cycles are repeated, which can efficiently and accurately separate individual crayfish.

[0043] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
