Description

Technical Field

[0001] The present invention relates to the technical field of aquatic product transportation, and in particular to a cold chain logistics transportation and transfer system for aquatic products. Background Art

[0002] Aquatic product cold chain logistics is a special supply chain system that involves all aspects of aquatic products from processing, storage, transportation, distribution to retail after being caught at the place of production. During this process, aquatic products are always kept in a suitable low-temperature controlled environment, aiming to maximize quality and quality safety, while reducing losses and preventing pollution; Since aquatic products are rich in nutrients such as protein and unsaturated fatty acids, they are easy to spoil at room temperature. Cold chain logistics can significantly delay the spoilage process of aquatic products by effectively inhibiting the growth and reproduction of microorganisms and the activity of enzymes, thereby maintaining freshness, taste and nutritional value. For example, seafood that needs to be frozen at low temperatures from deep-sea fishing should be pre-cooled as soon as possible after being caught and loaded onto the ship, and then diverted and transported one by one when arriving at the designated unloading and transshipment area. This technology is of vital importance to maintaining the excellent quality of aquatic products, extending the shelf life and meeting the needs of consumers.

[0003] In conjunction with the above content, it should be explained that: the Chinese patent with announcement number CN215515352U discloses a cold chain logistics conveying device for aquatic products, which uses an inclined plate guide to reduce the rigid contact between the frozen aquatic products and the conveying equipment, and sprays low-temperature cold water on the conveyed aquatic products, and recycles the low-temperature cold water; however, during actual use, the transportation and processing environment of the aquatic products cold chain conveyed is in a low-temperature cold storage, and the low-temperature water spraying can easily cause secondary freezing of the aquatic products, freezing of the conveyor belt, and temporary freezing of the aquatic products on the conveyor belt by the water spraying. At the same time, after the accumulated water on the conveyor belt freezes, the aquatic products that slide obliquely onto the conveyor belt are prone to slide on the ice surface, causing collision and accumulation between the aquatic products, resulting in transportation blockage and damage to the aquatic products themselves; In view of the above technical defects, a solution is now proposed.

An infrared scanning sensor close to the feed board is embedded on the inner wall of one end of the transfer conveyor rack, and the infrared scanning sensor is used to collect the external volume of the passing aquatic products.

[0008] Furthermore, a rotating frame hinged to the transfer conveyor frame is provided at the bottom of the feed board, and a weighing sensor connected to the feed board is embedded in the top center of the rotating frame. The weighing sensor is used to collect the dead weight of the aquatic products entering the transfer conveyor frame.

[0009] Furthermore, side support walls connected to the transfer conveyor frame are arranged at the bottom of both sides of the anti-slip cylinder cover, and the side support walls are connected to the deceleration soft plate, a sleeve frame is arranged on the top outer wall of the deceleration soft plate, and a rotary cylinder connected to the side support wall is arranged at one end of the sleeve frame, a feed hopper cover is arranged on the top of one end of the anti-slip cylinder cover, a plurality of suction holes are arranged on the inner wall of the feed hopper cover, and an arc-shaped guardrail is arranged on the edge of the inner wall of the feed hopper cover.

[0010] Furthermore, the annular spray frame is embedded in the inner wall of the top of the anti-slip cylinder cover at equal intervals, and the annular spray frame is composed of multiple groups of upper high-pressure nozzles and metal frames. An air supply duct connecting the annular spray frame and the feed hopper cover is arranged on the outer wall of the top of the anti-slip cylinder cover, and an air intake pipe and an air return pipe are arranged inside the air supply duct. Multiple groups of buffer curtains are arranged on the inner wall of one end of the anti-slip cylinder cover close to the buffer transfer platform.

[0011] Furthermore, a hollow frame close to the transfer conveyor frame is arranged on the top of the buffer transfer platform, an elastic cloth is arranged on the top of the hollow frame, a plurality of gaps are arranged in the connection area between the elastic cloth and the hollow frame, and a slag collecting trough is arranged inside the hollow frame.

When the frozen products fall onto the elastic cloth, the residual inertia force is absorbed by the deformation of the elastic cloth, and the guiding unloading design of the flip guide frame and the extension frame is used to further reduce the impact damage of the frozen products, thereby realizing the classification and processing of frozen products of different weights.

[0016] 3. The present invention realizes the flexible pushing and moving of the stranded frozen products through the cooperation of the extension frame through the pushing cylinder and the sliding block, and the turning guide frame is adjusted by the lifting cylinder to form the tilting, stretching and contraction of the turning guide frame body, which greatly improves the work efficiency and flexibility.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Fig.10 As shown, this embodiment is a cold chain logistics transportation and transfer system for aquatic products, including a transfer conveyor frame 1, a top of the transfer conveyor frame 1 is provided with an anti-slip barrel cover 2, a top of one end of the transfer conveyor frame 1 is provided with a feed sling 5, and a buffer transfer platform 3 is provided at the other end of the transfer conveyor frame 1. A plurality of groups of deceleration soft plates 6 are provided on the inner wall at the bottom of the anti-slip barrel cover 2, and a plurality of groups of ring spray racks 205 are provided on the inner wall at the top of the anti-slip barrel cover 2; While waiting for the deep-sea fishing refrigeration equipment to approach the feed port of the transfer warehouse and dock with it, the gas pipeline is connected to the output end of the gas supply equipment inside the warehouse through the air inlet pipe, providing high-pressure airflow for the ring spray rack 205 and the lower spray rack 103. The return air pipe is connected to the input end of the gas supply equipment to extract the cold air sprayed outside the area near the feed hopper cover 202, forming a pneumatic circulation.

[0022] A support frame 101 is arranged at the bottom of the transfer conveyor frame 1, a conveyor belt 102 is arranged above the support frame 101, a drainage trough 104 is arranged at the bottom of the support frame 101 near one end of the buffer transfer platform 3, and a water collecting trough is arranged in a recessed manner on the top of the support frame 101 to cover the area below the conveyor belt 102.

[0023] A plurality of lower spray racks 103 are arranged inside one end of the conveyor belt 102 close to the buffer transfer platform 3. The lower spray rack 103 includes a rotating shaft and a lower high-pressure nozzle. An infrared scanning sensor close to the feed board 5 is embedded on the inner wall of one end of the transfer conveyor rack 1. The infrared scanning sensor is used to collect the external volume of the aquatic products passing through. The feed board 5 is attached to the discharge port of the refrigeration equipment through a rotating frame 501, and the aquatic products are taken out one by one from the inside of the refrigeration equipment. When the aquatic products pass through the feed board 5, the weighing sensor installed inside the feed board 5 collects the deadweight ratio Zz of the frozen products and communicates and stores it in the database of the main control center.

[0024] A rotating frame 501 hinged to the transfer conveyor frame 1 is provided at the bottom of the feed plate 5, and a weighing sensor connected to the feed plate 5 is embedded in the center of the top of the rotating frame 501. The weighing sensor is used to collect the dead weight of the aquatic products entering the transfer conveyor frame 1. The weighing sensor and the infrared scanning sensor are connected to the external main control room to form a cold chain transfer supervision system; After being pushed by the internal force of the refrigeration equipment, the frozen products pass through the feed raft 5 and enter the transfer conveyor rack 1. The conveyor belt 102 rotates at a constant speed, causing the approaching frozen products to be pulled to the surface of the conveyor belt 102, and under the traction of its own weight and the conveyor belt 102, it slides along the surface of the conveyor belt 102 to the buffer transfer platform 3. When the frozen products pass through the infrared scanning sensor, it is used to collect the external volume value Wx of the frozen products and communicate and store it in the database of the main control center.

[0025] When the main control center obtains the self-weight ratio Zz and the external volume value Wx, it immediately retrieves the preset weight ratio range threshold and external volume range threshold of the sample from the database for comparison with the self-weight ratio Zz and the external volume value Wx: If the deadweight ratio Zz is greater than the average value of the preset weight ratio range threshold, and the external volume value Wx is greater than the average value of the external volume ratio range threshold, a deceleration signal is generated and sent to the control center in the general control room. The control center communicates and controls the operation of the internal and external gas supply equipment in the transit warehouse and the electrical control components on the operating conveyor rack.

[0026] The annular spray rack 205 and the lower spray rack 103 are started at the same time. The connection parts of the multiple annular spray racks 205, the lower spray rack 103 and the air inlet pipe are provided with regulating valves. The regulating valves adjust the output of the multiple annular spray racks 205. The output of the annular spray racks 205 and the lower spray racks 103 increases from one end of the transfer conveyor rack 1 to the buffer transfer platform 3. The closer the frozen products are to the buffer transfer platform 3, the greater the impact of the airflow they are subjected to, forming multiple sets of triangular counter-impact airflow resistance areas β in the transport cavity between the conveyor belt 102 and the anti-slip cylinder cover 2; like Fig.10 As shown, when the triangular counter-flow airflow resistance area β is formed, the surface of the frozen product passing through is flushed by the high-pressure airflow, so that impurities that are easy to fall off the surface of some frozen products are cleaned separately, and the air passing through the transport cavity close to the feed hopper cover 202 is sucked by the suction holes on the inner wall of the feed hopper cover 202 for pneumatic circulation.

[0027] If the deadweight ratio Zz is greater than the maximum value of the preset weight ratio range threshold, and the external volume value Wx is greater than the maximum value of the external volume ratio range threshold, a stop signal is generated, and the generated stop signal is sent to the control center in the general control room, and the control center controls the operation of the internal and external gas supply equipment of the transfer warehouse and the operation of the electric control components on the conveyor rack; In addition to adjusting the air supply to the transfer conveyor rack 1, the external servo motor used to drive the conveyor belt 102 starts to adjust the speed, reducing the transportation efficiency of the conveyor belt 102, and increasing the friction between the surface of the frozen product and the conveyor belt 102, so that the combined acceleration force of the frozen product on the conveyor belt 102, such as the tilt angle of the transfer conveyor rack 1, the weight of the frozen product, and the inertia of the frozen product, is weakened; At the same time, the rotary cylinder 602 drives the sleeve 601 to rotate, causing the deceleration soft plate 6 to separate from the side support wall 201 and move into the transport cavity above the anti-tube cover and the conveyor belt 102. During the period of rotation and opening, the gap between the same row of the parallel deceleration soft plates 6 close to one end of the transfer conveyor frame 1 is the largest, and the spacing between the same row of deceleration soft plates 6 toward one end of the buffer transfer platform 3 decreases until it is close to the maximum value of the outer peripheral diameter of the frozen product's outer volume value Wx, causing the frozen product to contact and decelerate with the surface of the deceleration soft plate 6 when moving along the surface of the conveyor belt 102, and the frozen product slides along the surface of the conveyor belt 102. When approaching the buffer transfer platform 3, the frozen product contacts the buffer curtain 203. The inner wall of the buffer curtain 203 is provided with an anti-slip rubber sleeve, which contacts the frozen product surface module for absorbing the inertial force of the sliding of the frozen product during transportation, and causing the frozen product to slowly fall onto the elastic cloth 302; If the self-weight ratio Zz is less than the average value of the preset weight ratio range threshold, and the shape volume value Wx is less than the average value of the shape ratio range threshold, no signal is generated.

[0028] The bottom of both sides of the anti-slip cylinder cover 2 are provided with side support walls 201 connected to the frame of the transfer conveyor frame 1, and the side support walls 201 are connected to the deceleration soft plate 6, and a sleeve frame 601 is provided on the top outer wall of the deceleration soft plate 6, and a rotary cylinder 602 connected to the side support wall 201 is provided at one end of the sleeve frame 601. A feed hopper cover 202 is provided on the top of one end of the anti-slip cylinder cover 2, and a plurality of suction holes are provided on the inner wall of the feed hopper cover 202, and an arc-shaped guardrail is provided on the edge of the inner wall of the feed hopper cover 202.

[0029] The annular spray frame 205 is embedded at equal intervals on the top inner wall of the anti-slip cylinder cover 2. The annular spray frame 205 is composed of multiple groups of upper high-pressure nozzles and metal frames. An air supply duct 204 connecting the annular spray frame 205 and the feed hopper cover 202 is arranged on the top outer wall of the anti-slip cylinder cover 2. An air inlet pipe and an air return pipe are arranged inside the air supply duct 204. Multiple groups of buffer curtains 203 are arranged on the inner wall of one end of the anti-slip cylinder cover 2 close to the buffer transfer platform 3.

[0030] Embodiment 2: This embodiment is a cold chain logistics transportation and transfer system for aquatic products, including a buffer transfer platform 3 with a pushing transfer platform 4 arranged side by side on the end face, a flip guide frame 7 is arranged between the buffer transfer platform 3 and the pushing transfer platform 4, and an inner arc frame 402 and an outer arc frame 403 are arranged on the top of the pushing transfer platform 4.

[0031] A hollow frame 301 close to the transfer conveyor frame 1 is arranged on the top of the buffer transfer platform 3, and an elastic cloth 302 is arranged on the top of the hollow frame 301. A plurality of gaps are arranged in the connection area between the elastic cloth 302 and the hollow frame 301, and a slag collecting trough is arranged inside the hollow frame 301. When the frozen products fall onto the elastic cloth 302, the elastic cloth 302 is impacted and deformed by the residual force of the transportation inertia force, and slides along the surface of the elastic cloth 302 toward the turning guide frame 7. The lighter frozen products can stay on the surface of the turning guide frame 7, while the heavier frozen products slide on the slippery surface 702 on the surface of the turning guide frame 7 until they are close to the extension frame 401.

[0032] An extension frame 401 connected to the inner arc frame 402 is arranged on the top of the pushing transfer platform 4, and a guide groove 405 is arranged in a depression in the middle of the extension frame 401. A pushing cylinder 404 is embedded in the extension frame 401, and a sliding block 406 sleeved in the guide groove 405 is arranged on the top of the pushing cylinder 404. A rotary cylinder 2 connected to the inner arc frame 402 is embedded in the middle of the sliding block 406. The top of the extension frame 401 forms a one-eighth eggshell structure through the inner arc frame 402 and the outer arc frame 403, so that when the frozen product contacts the inner wall of the inner arc frame 402, if there is excess inertia force, it is pulled upward along the inner wall of the inner arc frame 402, and then the outer arc frame 403 intercepts the air unloading force, so that the frozen product stays on the surface of the extension frame 401.

[0033] The extension frame 401 drives the sliding block 406 to move axially along the guide groove 405 by pushing the cylinder 404. The sliding block 406 drives the inner arc frame 402 to move along the surface of the extension frame 401 toward the flip guide frame 7, and pushes the frozen products stranded on the extension frame 401 to move synchronously. When approaching the flip guide frame 7, the main control center controls the start of the rotary cylinder 2 and the lifting cylinder 701 through the signal generated when the frozen products pass through the transfer conveyor frame 1. The rotary cylinder 2 drives the inner arc frame 402 to deflect, prompting the inner arc frame 402 to push the frozen products to one side of the two sides of the surface of the flip guide frame 7.

[0034] Lifting cylinders 701 embedded in the inner walls of the buffer transfer platform 3 and the push material transfer platform 4 are arranged at the bottom of both ends of the flip guide frame 7. A sliding surface 702 is laid on the top of the flip guide frame 7. The flip guide frame 7 is adjusted by the extension of the lifting cylinder 701. When the lifting cylinder 701 on one side of the flip guide frame 7 slides down, the other side slides down with its deceleration, causing one side of the flip guide frame 7 to tilt downward. The frame body of the flip guide frame 7 is composed of two groups of sliding sleeved metal rods, which are convenient for extension and contraction during the side sliding and tilting, and the bottom of both ends of the metal rods are rotatably sleeved with the lifting cylinder 701.

[0035] Combining the first and second embodiments, it can be known that the real-time data of the frozen products passing through can be collected and analyzed to generate relevant signals, so as to realize fine control of the frozen product transportation, and the air supply equipment and the conveyor belt 102 speed can be adjusted according to the comparison between the real-time collected data and the preset threshold value. The pneumatic circulation design not only provides high-pressure airflow, but also forms a triangular counter-flow airflow resistance area, so as to effectively clean the frozen product impurities; For overweight or oversized frozen products, the deceleration design and elastic buffering can ensure stable and safe transportation while achieving classification processing. The flexible adjustment of the extension rack 401 and the flip guide rack 7 can further improve work efficiency and flexibility, and realize the flexible pushing and moving of stranded frozen products, as well as the tilting, extension and contraction of the rack.
