Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically to a crab processing and cleaning machine. Background Technology
[0002] Crabs are a delicious seafood, but because their shells and claws may be covered with mud, algae, and other impurities, they need to be cleaned before processing. Currently available crab cleaning equipment only performs a simple cleaning of the carapace. For example, Chinese Patent Publication No. CN209825035U discloses a crab cleaning production line that transports crabs on a conveyor table and then rinses them through spray nozzles above the table. However, this cleaning method cannot effectively clean the crab's abdomen, resulting in poor cleaning results. Utility Model Content

[0015] The first mesh clamp is provided with connecting parts on both sides, the connecting parts are provided with through grooves, and the two sides of the through grooves are provided with several vertically arranged through holes. The second mesh clamp is provided with handrails and protrusions for cooperating with the through grooves on both sides, and the protrusions are provided with elastic positioning pins for cooperating with the through holes.
[0016] The spray heads are arranged in at least two rows, and the brush strips are located between the front and rear spray heads, with the front and rear spray heads arranged in an alternating pattern.
[0017] The water tank is provided with a filtration zone, and the filtration zone is provided with a filter screen and a slot for engaging with the filter screen.
[0018] A connecting plate is provided between the telescopic element and the brush strip, and an elastic reset member is provided between the brush strip and the connecting plate.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0030] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the crab processing and cleaning machine includes a water tank 1, a water pump 2 installed on one side of the water tank 1, and also includes:
[0031] Support 3 is set at both the front and rear ends of water tank 1;
[0032] The No. 1 mesh clamping plate 4 is rotatably installed between the No. 1 brackets 3, and the No. 1 mesh clamping plate 4 is equipped with a power device 5;
[0033] The No. 2 mesh clamping plate 6 is used to detachably engage with the No. 1 mesh clamping plate 4.
[0034] The second bracket 7 is set at the left and right ends of the water tank 1 respectively;
[0035] The horizontal moving mechanism 8 is respectively installed on the top surface of the second bracket 7;
[0036] The cleaning rack 9 is set on the horizontal moving mechanism 8 and located above the No. 1 mesh clamping plate 4 and the No. 2 mesh clamping plate 6;
[0037] Spray head 10 is mounted on cleaning rack 9 and connected to water pump 2;
[0038] A brush strip 11 is mounted on a cleaning frame 9, and the brush strip 11 is equipped with a telescopic element 12.
[0039] The horizontal moving mechanism 8 is a synchronous slide table, the telescopic element 12 is an electric cylinder, and the first mesh clamping plate 4 and the second mesh clamping plate 6 work together to form a clamping plate assembly for clamping the crab. The power unit 5 is a geared motor. The horizontal moving mechanism 8 drives the cleaning frame 9 to move along the front and back direction of the clamping plate assembly, which in turn drives the spray head 10 and the brush strip 11 to brush the crabs on all parts of the clamping plate assembly. After one side of the crab is brushed, the power unit 5 drives the clamping plate assembly to flip over, so that the other side of the crab can be brushed, ensuring that the crab is completely cleaned and the cleaning effect is good.
[0040] In the embodiments, such as Figure 4 , Figure 5 As shown, the distance between the first mesh clamp 4 and the second mesh clamp 6 is adjustable. By adjusting the distance between the first mesh clamp 4 and the second mesh clamp 6, crabs of different sizes can be clamped.
[0041] In the embodiments, such as Figure 4 , Figure 5 As shown, the first mesh clamping plate 4 has connecting portions on both sides, each connecting portion having a through groove 13. The through groove 13 has several vertically arranged through holes 14 on both sides. The second mesh clamping plate 6 has handles 15 on both sides and protrusions 16 for engaging with the through grooves 13. Each protrusion 16 has elastic positioning pins 17 for engaging with the through holes 14. The elastic positioning pins 17 can adjust the distance between the first mesh clamping plate 4 and the second mesh clamping plate 6 by engaging with the through holes 14 at different positions, and the first mesh clamping plate 4 and the second mesh clamping plate 6 are easy to assemble and disassemble.
[0042] In the embodiments, such as Figure 1 , Figure 3 As shown, the spray heads 10 are arranged in at least two rows, and the brush strips 11 are located between the front and rear spray heads 10, with the front and rear spray heads 10 arranged in an alternating pattern. Through the rinsing, brushing, and washing by the spray heads 10 and the brush strips 11, the crabs are ensured to be cleaned.
[0043] In the embodiments, such as Figure 1 , Figure 2 As shown, the water tank 1 is equipped with a filtration zone, which contains a filter screen 18. The filtration zone also includes a connector slot 19 for engaging the filter screen 18. This allows the rinsing water to be reused multiple times, and the filter screen 18 can be easily replaced.
[0044] In the embodiments, such as Figure 1 , Figure 3 As shown, a connecting plate 20 is provided between the telescopic element 12 and the brush strip 11, and an elastic reset member 21 is provided between the brush strip 11 and the connecting plate 20. The brush strip 11 is provided with a guide rod 22 for cooperating with the connecting plate 20, and a limiting block 23 is provided at the top of the guide rod 22. The limiting block 23 is located on the top surface of the connecting plate 20. The telescopic element 12 is an electric cylinder, and the elastic reset member 21 is a spring. The brush strip 11 can float upward to prevent the brush strip 11 from being pressed too tightly, which would affect the life of the brush bristles and the smoothness of the brush strip 11's movement.
[0045] In this embodiment, the No. 1 mesh clamping plate 4 and the No. 2 mesh clamping plate 6 are made of stainless steel. The No. 1 mesh clamping plate 4 and the No. 2 mesh clamping plate 6 are not easy to rust, have good corrosion resistance, will not cause secondary pollution to crabs, and have a long service life.
[0046] In the embodiments, such as Figure 1 , Figure 2 As shown, a booster 24 is also provided between the water pump 2 and the spray head 10. The booster 24 is connected to the spray head 10 by a hose, and the length of the hose is sufficient to allow the spray head 10 to move to the farthest position. The booster 24 can increase the water pressure sprayed from the spray head 10, making it easier to rinse the crabs clean.
[0047] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
