Description

Technical Field

[0001] This utility model relates to the field of crayfish processing technology, specifically to an automatic cleaning machine for crayfish processing. Background Technology

[0002] Crayfish, also known as red swamp crayfish, are a type of freshwater economic shrimp. They have robust bodies covered by a hard carapace. Their bodies consist of a cephalothorax and an abdomen. The cephalothorax is slightly larger and has five pairs of walking legs. The abdomen is relatively short and narrower than the head. The telson lacks appendages and is slightly conical. They are widely popular due to their delicious meat.

[0003] Currently, there are two main types of crayfish cleaning devices on the market. One type uses ultrasonic waves to clean crayfish, but this method, which uses high-frequency vibrations to generate bubbles, is not very effective at cleaning stubborn stains. The other type involves guiding the crayfish through multiple sets of rotating roller brushes for cleaning. This type of device is cheaper and easier to maintain, but the crayfish are tumbling around in the irregular roller brushes, which can easily cause them to die and affect the taste. The removal of the crayfish's intestinal tract often involves manual operation or removal after cooking by opening the back. However, the intestinal tract is prone to breakage after cooking, resulting in incomplete removal. Utility Model Content

[0004] This application proposes an automatic cleaning machine for crayfish processing, which has the advantages of reducing the rolling of crayfish, reducing the mortality rate of crayfish, directional cleaning of the thorax and abdomen of crayfish, and removing the shrimp vein of live crayfish. It solves the problems of poor cleaning power for stubborn stains, high crayfish mortality, and reducing the need for manual removal of the shrimp vein.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic cleaning machine for crayfish processing, comprising: a water tank, a double spiral conveying cleaning device, a rotating mechanism, a suction device, a brush cleaning device, and a shrimp vein extraction device.

The end face of the steering component away from the support block is installed at the lower end of the rotating assembly. A spoon-shaped component is installed on the long rod away from the support block. The spoon-shaped component is designed to simulate the shape of a crayfish, with a wide head and narrow tail. The front end of the spoon-shaped component is arc-shaped. The upper end face of the spoon-shaped component extends downward from the middle to the tail end in an arc. An air bladder is installed on the upper end face of the spoon-shaped component. A suction cup assembly is installed inside the lower end of the spoon-shaped component. An air tube is provided at one end of the air bladder. The air bladder is connected to the suction cup assembly through the air tube.

[0009] Furthermore, the spring, support block, steering component, long rod, spoon-shaped component, airbag, and suction cup assembly form a set of eight, which together form a disc-shaped suction device when viewed from above, with the rotating assembly as the center.

[0012] This utility model has the following beneficial effects:

[0013] 1. This application provides an automatic cleaning machine for crayfish processing. The machine uses two spiral rods (left and right) to push the crayfish along two different rotational directions. The crayfish moves forward along the spiral direction at the midpoint between the left and right spiral rods. During this process, a sponge strip cleans the carapace of the cephalothorax. This reduces the crayfish's rotation during cleaning, achieving a more comprehensive cleaning of the carapace and sides of the crayfish's cephalothorax. Furthermore, reducing the crayfish's rotation during cleaning prevents leg breakage and ensures the crayfish's integrity.

[0014] 2. The automatic cleaning machine for crayfish processing provided in this application uses a rotating shaft to drive a spoon-shaped part to move towards a brush cleaning device. At this time, the brush motor runs and drives the transmission gear and brush to rotate. The rotation of the brush rolls and brushes the thorax and abdomen of the crayfish, realizing the directional rotation cleaning of the thorax and abdomen of the crayfish by the brush. This avoids the death of a large number of crayfish due to irregular rotation, ensuring the freshness of the crayfish. Moreover, the directional cleaning of the thorax and abdomen of the crayfish improves the cleaning effect of the crayfish.

[0015] 3. The automatic cleaning machine for crayfish processing provided in this application drives the spoon-shaped part 5 to continue rotating to the position of the shrimp vein extraction device through the rotating shaft. The shrimp vein extraction device uses the cooperation of the second pulley and the cylinder to extract the shrimp vein from the rotating crayfish. The shrimp vein of the crayfish is part of the intestine and contains a large amount of heavy metals and excrement. Removing it improves the taste of the crayfish after processing and reduces the impact on the health of consumers. It eliminates the need for manual removal of the shrimp vein, thus reducing the waste of manpower and resources. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10An automatic cleaning machine for crayfish processing includes: a water tank 1, a double-spiral conveying cleaning device 2, a rotating mechanism 3, a suction device 4, a brush cleaning device 5, and a crayfish vein extraction device 6. A conveyor belt 102 is placed above the water tank 1. Multiple sets of crescent-shaped baffles 103 are arranged on the surface of the conveyor belt 102. A material distribution plate 104 is placed at the end of the conveyor belt 102 away from the water tank 1. A conical strainer 105 is fixedly installed at the end of the material distribution plate 104 away from the conveyor belt 102. Two sets of conical strainers 105 are arranged. The double-spiral conveying cleaning device 2 is respectively arranged below the two sets of conical strainers 105. A vibration motor 106 is fixedly installed on the lower end face of the material distribution plate 104. Spring brackets 107 are provided at the four corners of the lower end face of the material distribution plate 104. The conveyor belt 102 is inclined and the position near the material distribution plate 104 is set as the highest point. The material distribution plate 104 extends inclinedly along the position of the conveyor belt 102 to the top of the double-spiral conveying cleaning device 2. The conveyor belt 102 transports crayfish from the water tank 1 to the sorting plate 104. The crescent-shaped baffle 103 is designed to accommodate only one crayfish, effectively preventing accumulation during transport. The vibration motor 106 then vibrates the sorting plate 104. The extension and retraction of the spring bracket 107 causes the sorting plate 104 to shake up and down. The shaking of the sorting plate 104 causes the crayfish to jump. Since the crayfish is head-heavy and tail-light, it is affected by gravity during the shaking and sliding process. The crayfish falls head-down into the conical strainer 105 and then falls from the conical strainer 105 to the top of the double spiral conveying cleaning device 2. A rotating mechanism 3 is placed at the end of the double-helix conveying cleaning device 2 away from the water tank 1. A suction device 4 is provided on the outer circumference of the rotating mechanism 3. The suction device 4 is used to suck up the back of the crayfish above the double-helix conveying cleaning device 2 and rotate it so that the crayfish leaves the upper position of the double-helix conveying cleaning device 2 for the next process. The suction device 4 is disc-shaped when viewed from above. A brush cleaning device 5 and a shrimp vein extraction device 6 are respectively placed on the circumference of the disc-shaped suction device 4. The brush cleaning device 5 is used to clean the thorax and abdomen of the crayfish sucked up by the rotating mechanism 3. The shrimp vein extraction device 6 is used to extract the shrimp vein from the tail of the crayfish after it has been cleaned by the brush cleaning device 5.

[0031] The double-helix conveying cleaning device 2 includes a left helical rod 201, a sponge strip fixing frame 202, a sponge strip 203, a first conveying motor 204, a second conveying motor 205, and a right helical rod 206. A right helical rod 206 is placed on one side of the left helical rod 201. The left and right helical rods 201 and 206 are arranged as a pair, and there are two pairs in total. The two pairs of left and right helical rods 201 and 206 are placed horizontally, with their relative positions relatively close. Crayfish positioned in the middle of the left and right helical rods 201 and 206 will not fall off. The spiral line on the surface of the left helical rod 201 is a clockwise spiral line. The spiral on the surface of the spiral rod 206 is set as a counterclockwise spiral. One end of the two pairs of left spiral rods 201 is connected in series with a first conveyor motor 204, and one end of the two pairs of right spiral rods 206 is connected in series with a second conveyor motor 205. A sponge strip fixing frame 202 is placed above the left spiral rod 201. A sponge strip 203 is fixedly installed on the side of the sponge strip fixing frame 202 near the left spiral rod 201. The sponge strip 203 is set in two groups of two, and there are two groups of sponge strips 203. Each group of sponge strips 203 is set above the two pairs of left spiral rods 201 and right spiral rods 206. The middle position of the two sponge strips 203 and the middle position of the left spiral rods 201 and right spiral rods 206 are used for crayfish to pass through. The first conveyor motor 204 starts, driving two pairs of left helical rods 201 to rotate clockwise. The second conveyor motor 205 starts, driving two pairs of right helical rods 206 to rotate counterclockwise. This causes the left and right helical rods 201 and 206 to rotate towards the middle position, i.e., inward rotation. When a crayfish falls between the left and right helical rods 201 and 206, if the crayfish is facing upward or sideways, due to the crayfish's body shape, its cephalothorax is smooth and oval-shaped, and its numerous walking legs result in a high coefficient of friction. The crayfish's walking legs pass through the left and right helical rods 201 and 206. The rotation of 06 causes the crayfish to rotate, so that the crayfish's back faces upwards. The crayfish's legs fall vertically in the middle position between the left spiral rod 201 and the right spiral rod 206. Finally, the spiral lines on the surfaces of the left spiral rod 201 and the right spiral rod 206 rotate along the side of the crayfish. Then, the spiral lines of the left spiral rod 201 and the right spiral rod 206 push the crayfish through two different rotation directions. The crayfish moves forward along the spiral line in the middle position between the left spiral rod 201 and the right spiral rod 206. During the process, the sponge strip 203 cleans the carapace of the cephalothorax. The crayfish comes out from the end of the left spiral rod 201 and the right spiral rod 206 near the rotating mechanism 3.

[0032] The rotating mechanism 3 includes a rotating shaft 301, a rotating assembly 302, a rotating motor 303, a circular inclined slide 304, and an inclined slide bracket 305. The rotating assembly 302 is fixedly sleeved on the outer circumferential surface of the rotating shaft 301. The rotating motor 303 is connected in series on the lower circumferential surface of the rotating shaft 301. The operation of the rotating motor 303 drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives the rotating assembly 302 to rotate. A circular inclined slide 304 is placed on the side of the rotating shaft 301 near the double helix conveying cleaning device 2. The horizontal position of the circular inclined slide 304 is set in a semi-circle. The lower end of the circular inclined slide 304 is set as a slope. The upper end of the circular inclined slide 304 near the left helical rod 201 is the widest part of the slope, and the position of the circular inclined slide 304 away from the left helical rod 201 is the narrowest part of the slope.

[0033] The suction device 4 includes a spring 401, a support block 402, a steering component 403, a long rod 404, and a spoon-shaped component 405. One end of the spring 401 is connected to the circumferential surface of the rotating assembly 302. The end of the spring 401 away from the rotating assembly 302 is connected to the support block 402. The long rod 404 is mounted on the side of the support block 402 away from the spring 401. The steering component 403 is movably mounted on the lower end face of the support block 402. The end face of the steering component 403 away from the support block 402 is mounted at the lower end of the rotating assembly 302. The long rod 405 is located away from the support block 401. A spoon-shaped component 405 is installed at position 402. The spoon-shaped component 405 is designed to mimic the shape of a crayfish, with a wide head and narrow tail. The front end of the spoon-shaped component 405 is curved, and its upper surface extends downwards from the middle to the tail end, with the crayfish's tail segment suspended at the tail end of the spoon-shaped component 405. An airbag 406 is installed on the upper surface of the spoon-shaped component 405, and a suction cup assembly 407 is installed inside the lower end of the spoon-shaped component 405. An air tube is provided at one end of the airbag 406, and the airbag 406 is connected to the suction cup assembly 407 via the air tube. Please refer to the appendix. Figure 4 The spring 401, support block 402, steering component 403, long rod 404, spoon-shaped component 405, airbag 406, and suction cup assembly 407 constitute a set of eight, forming a disc shape with the rotating assembly 302 as the center, referred to as the disc suction assembly. The disc suction assembly of this application can be set according to actual needs. The rotating motor 303 drives the rotating assembly 302 to rotate. The rotating assembly 302 drives the support block 402 and spoon-shaped component 405 to rotate through the spring 401 and steering component 403 connected to it. The direction of rotation is always forward at the wide part of the spoon-shaped component 405.

[0034] Please see the appendix Figure 4The rotating mechanism 3 and the suction device 4 are set together in two groups, left and right, respectively located above the two pairs of left and right spiral rods 201 and 206. The spoon-shaped part 405 is located above the middle position of the left and right spiral rods 201 and 206. The rotation direction of both rotating mechanisms 3 and suction devices 4 is forward with the width of the spoon-shaped part 405 as the forward direction. Therefore, the left rotating mechanism 3 and suction device 4 rotate counterclockwise, and the right rotating mechanism 3 and suction device 4 rotate clockwise. During rotation, when the left and right helical rods 201 and 206 transport the crayfish to below the widest point of the circular inclined slide 304, the spoon-shaped component 405 reaches this position through the rotation of the rotating shaft 301. The spoon-shaped component 405, due to the setting of the widest point of the circular inclined slide 304, has a certain tilt angle. This tilt causes the spring 401 to stretch towards the spoon-shaped component 405. The purpose of this tilt is to better fit the carapace of the crayfish's cephalothorax. Simultaneously, the air bladder 406 is continuously compressed by the circular inclined slide 304 from its narrowest point to its widest point, causing the air inside the air bladder 406 to be drawn out by the suction cup assembly 407. When the spoon-shaped part 405 covers the carapace and tail of the crayfish's cephalothorax, the suction cup assembly 407 adheres to the top of the carapace and tail. The rotation of the spoon-shaped part 405 pushes the crayfish away from the circular oblique slide 304. Without the pressure of the circular oblique slide 304, the air bladder 406 retracts, but the air inlet of the suction cup assembly 407 is blocked by the carapace of the crayfish's cephalothorax. The air bladder 406 cannot draw in a large amount of air, resulting in negative air pressure inside the air bladder 406. This causes the suction cup assembly 407 to firmly suck the crayfish away from the top of the left spiral rod 201. The spring 401 retracts until the spoon-shaped part 405 returns to the horizontal position. The rotation of the rotating shaft 301 brings the crayfish into the position of the brush cleaning device 5.

[0035] The brush cleaning device 5 includes a brush holder 501, an L-shaped frame 502, a brush motor 503, a C-shaped frame 504, and a first pulley 505. The top end of the brush holder 501 is fixedly connected to the C-shaped frame 504. The first pulley 505 is sleeved on one side of the upper end of the C-shaped frame 504. A transmission gear 506 is installed at the lower end of the C-shaped frame 504. A brush 507 is fixedly installed on the side of the transmission gear 506 away from the C-shaped frame 504. The L-shaped frame 502 is fixedly installed on the upper side of the brush holder 501. The brush motor 503 is fixedly installed at the end of the L-shaped frame 502 away from the brush holder 501. The motor shaft of the brush motor 503 overlaps the circumferential surface of the transmission gear 506. When the crayfish reaches below the first pulley 505, the first pulley 505 slightly presses down the spoon-shaped part 405, and the brush motor 503 runs to drive the transmission gear 506 and the brush 507 to rotate. The rotation of the brush 507 rolls and brushes the thorax and abdomen of the crayfish. After the crayfish is cleaned, it continues to rotate towards the position of the shrimp vein extraction device 6.

[0036] The shrimp vein extraction device 6 includes a vertical rod 601, a spherical support 602, an upper displacement rod 603, a second pulley 604, a lower displacement rod 605, and a cylinder 606. The spherical support 602 is fixedly installed on one side of the upper end of the vertical rod 601. The upper displacement rod 603 and the lower displacement rod 605 are movably installed on the side of the spherical support 602 away from the vertical rod 601. The upper displacement rod 603 and the lower displacement rod 605 move up and down inside the spherical support 602. The upper displacement rod 603 moves away from the spherical support 602. A second pulley 604 is movably installed at one end. A square frame 6031 is movably installed at the middle of the upper displacement rod 603. A rack 6032 is fixedly installed on the inner upper side of the square frame 6031. A cylinder 606 is fixedly installed at the end of the lower displacement rod 605 away from the spherical support 602. A gear support frame 6051 is movably installed at the middle of the lower displacement rod 605. A gear 6052 is installed at the end of the gear support frame 6051 away from the lower displacement rod 605. The gear 6052 meshes with the rack 6032. When the spoon-shaped component 405 rotates to the position of the second pulley 604, the arc-shaped front end of the spoon-shaped component 405 lifts the second pulley 604. The upward movement of the second pulley 604 causes the upper displacement rod 603 to rise. As the upper displacement rod 603 rises, the square frame 6031 is pulled by the gear support frame 6051. The square frame 6031 and the gear support frame 6051 gradually move away from the spherical support component 602. During the process of moving away, the gear 6052 on the gear support frame 6051 meshes and moves along the surface of the rack 6032. During the process of moving away from the spherical support component 602, the gear support frame 6051 causes the lower displacement rod 605 to move downward. The process of the square frame 6031 and the gear support frame 6051 moving away from the spherical support component 602 causes the second pulley 604 and... The increased distance between the cylinder 606 and the spoon-shaped component 405 allows the crayfish to pass through. The second pulley 604 rolls along the upper surface of the spoon-shaped component 405 until it reaches the middle arc-shaped position of the spoon-shaped component 405 and gradually lowers. The downward movement of the second pulley 604 causes the square frame 6031 and the gear support frame 6051 to gradually move closer to the spherical support component 602, so that the positions of the second pulley 604 and the cylinder 606 gradually approach each other. When the spoon-shaped component 405 rotates to the position of the crayfish's tail segment between the second pulley 604 and the cylinder 606, the second pulley 604 and the cylinder 606 come close together and clamp the crayfish's middle shrimp vein segment. The spoon-shaped component 405 continues to rotate, so that the second pulley 604 and the cylinder 606 clamp the shrimp vein of the tail segment for extraction.

[0037] The working principle of the specific implementation method is as follows: The operator puts the crayfish into the water tank 1, and the conveyor belt 102 transports the crayfish to the top of the distribution plate 104. The distribution plate 104, through the vibration of the vibration motor 106, causes the crayfish to fall headfirst into the conical strainer 105. Through the conical structure of the conical strainer 105, the crayfish fall vertically into the adjacent positions of the left spiral rod 201 and the right spiral rod 206 of the double spiral conveying cleaning device 2. The first conveyor motor 204 and the second conveyor motor 205 are activated. The movement causes the left and right spiral rods 201 and 206 to rotate in different directions, propelling the crayfish forward. During this forward movement, the sponge strip 203 above the left spiral rod 201 cleans the crayfish's cephalothorax. When the crayfish moves along the left and right spiral rods 201 and approaches the spoon-shaped component 405, the suction cup assembly 407 inside the spoon-shaped component 405 is compressed by the circular inclined slide 304 through the air bladder 406. The generated negative air pressure causes the suction cup assembly 407 to firmly adhere to the carapace of the crayfish's cephalothorax. The rotating shaft 301 then rotates, moving the spoon-shaped component 405 towards the brush cleaning device 5. The crayfish's thorax and abdomen on the spoon-shaped component 405 are brushed by the rotating brush 507. After the crayfish's thorax and abdomen are cleaned, the rotating shaft 301 continues to rotate the spoon-shaped component 405 to the position of the crayfish vein extraction device 6. Through the combined action of the second pulley 604 and the cylinder 606 on the crayfish vein extraction device 6, the rotating crayfish... The shrimp vein is extracted. Finally, the rotating shaft 301 drives the spoon-shaped part 405 to rotate to the narrowest point of the slope of the circular inclined slide 304. The air bladder 406 on the rotating spoon-shaped part 405 is gradually subjected to the force of the slope of the circular inclined slide 304. The air bladder 406 is squeezed and breaks the negative pressure difference that the suction cup assembly 407 absorbs from the crayfish. The negative pressure in the air bladder 406 disappears, and the suction cup assembly 407 does not have enough negative pressure difference to hold the crayfish, causing the crayfish to fall. The crayfish are collected at this position, and the entire crayfish cleaning work is completed.

[0038] The gap between the adjacent left spiral rod 201 and right spiral rod 206 in the double spiral conveying cleaning device 2 of this application can filter out larger particles, stones, or other impurities. The sponge strip 203 cleans the carapace and sides of the crayfish's cephalothorax and reduces the rotation of the crayfish during the cleaning process, achieving a more comprehensive cleaning of the carapace and sides of the crayfish's cephalothorax. Furthermore, reducing the rotation of the crayfish during the cleaning process prevents the crayfish from breaking off its legs and ensures the integrity of the crayfish.

[0039] The rotating mechanism 3 and the suction device 4 drive the crayfish through the brush cleaning device 5, achieving directional rotational cleaning of the crayfish's thorax and abdomen by the brush 507. This avoids irregular rotation that could cause a large number of crayfish to die, ensuring the crayfish's freshness. Furthermore, the directional cleaning of the crayfish's thorax and abdomen improves the cleanliness of the crayfish.

[0040] The rotating mechanism 3 and the suction device 4 drive the crayfish through the shrimp vein extraction device 6, thereby achieving the extraction of the shrimp vein from the crayfish by the second pulley 604 and the cylinder 606. The shrimp vein of the crayfish is part of the intestine and contains a large amount of heavy metals and excrement. Removing it improves the taste of the crayfish after processing and reduces the impact on the health of consumers. There is no need for manual removal of the shrimp vein, which reduces the waste of manpower and resources.
