Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a mud and sand cleaning device for lobster processing. Background Technology

[0002] In lobster processing lines, lobsters freshly caught from ponds often have a large amount of mud, sand, and algae attached to their bodies. Small mud particles can easily accumulate in the abdominal folds and claw crevices. If not cleaned properly, this can affect the taste and food safety during subsequent cooking. This is where lobster processing mud and sand cleaning equipment comes in. It's an automated cleaning device specifically designed for lobster pre-processing. Through a specific structure, it removes mud and sand from the lobster's surface and crevices, providing clean raw materials for subsequent sorting, steaming, and shelling processes. It is widely used in the pre-processing sections of lobster processing plants and aquatic food companies.

[0003] Existing lobster mud and sand cleaning equipment mostly uses spraying and stirring. The lobsters are sent into the cleaning chamber by a conveyor belt. The high-pressure spray head in the chamber sprays water to rinse the surface of the lobsters. At the same time, the bottom stirring rod slowly stirs the lobsters so that the water can contact the lobsters at different angles, and finally completes the basic cleaning.

[0004] In existing technologies, some mud and sand cleaning equipment uses high-pressure spray equipment where the water flow is mostly direct or oblique, making it difficult to penetrate the folds of the lobster's abdomen and the small gaps in the claw joints to wash away the surface mud. As a result, some mud and sand remain in the crevices of the lobster after cleaning, requiring manual secondary sorting and cleaning. Therefore, a mud and sand cleaning equipment for lobster processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mud and sand cleaning device for lobster processing, which aims to improve the problem that some existing mud and sand cleaning devices cannot penetrate the crevices of lobsters, resulting in incomplete mud and sand cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mud and sand cleaning device for lobster processing includes a cleaning tank with multiple brush rollers rotatably connected inside. A cleaning and filtration mechanism is installed inside the cleaning tank, and a water discharge and mud-removing mechanism is installed on the bottom side of the cleaning tank. The cleaning and filtration mechanism includes a support plate, which is fixedly connected to the outside of the cleaning tank. A braking assembly is installed on the top of the support plate.

Two limiting strips are fixedly connected inside the two strip-shaped grooves, and a manual baffle is slidably connected to the outside of the limiting strips. Two cylinders are fixedly connected inside the cleaning tank, and a connecting block is fixedly connected to the driving end of each cylinder. A telescopic rod is fixedly connected to the outside of the connecting block, and a filter screen is fixedly connected to the driving end of the telescopic rod.

[0008] As a further description of the above technical solution:

[0009] The water discharge and sludge removal mechanism includes a water discharge and sludge removal piston, which is externally slidably connected to the inside of the bottom side of the cleaning tank, and a motor is fixedly connected to the outside of the bottom side of the cleaning tank.

[0010] As a further description of the above technical solution:

[0011] The filter screen is slidably connected to the outside of the manual baffle. Handles are provided on both sides of the outside of the manual baffle, and the handles are slidably connected to the inside of the strip groove.

[0012] As a further description of the above technical solution:

[0013] The braking assembly includes a motor, the bottom of which is fixedly connected to the top of the support plate, the outside of which is fixedly connected to the outside of the cleaning tank, and a worm gear fixedly connected to the drive end of the motor.

[0014] As a further description of the above technical solution:

[0015] The cleaning tank is internally connected to multiple worm gears, and the outer surfaces of the worm gears and the outer surfaces of the worm are meshed with each other.

[0016] As a further description of the above technical solution:

[0017] A brush roller is fixedly connected to the outside of the worm gear, and the brush roller is slidably connected to the outside of the manual baffle.

[0020] As a further description of the above technical solution:

[0021] The cleaning tank has two fixedly connected internally, and the transmission connecting plate 2 is externally slidably connected to the internal of the limiting blocks. The transmission connecting plate 2 is externally fixedly connected to a scraper, and the scraper is externally slidably connected to the internal bottom side of the cleaning tank.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor drives the worm gear and worm wheel to drive the brush roller to achieve efficient brushing.

[0035] 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.

[0036] Example:

[0037] A mud and sand washing device for lobster processing, referring to Figures 1 to 3 The system includes a cleaning tank 1, with multiple brush rollers 2 rotatably connected inside the cleaning tank 1. The brush rollers 2 physically scrub the surface of the lobsters by rotating the surface brushes, and remove mud and impurities with the help of water flow. The cleaning tank 1 is equipped with a cleaning and filtration mechanism 3, which integrates cleaning drive and filtration separation functions. It provides power to the brush rollers 2 and can separate the lobsters from the water after cleaning. The bottom of the cleaning tank 1 is equipped with a water discharge and mud removal mechanism 4, which is used to discharge the cleaning wastewater and clean the mud and sand accumulated at the bottom of the tank to avoid the residue of impurities affecting subsequent cleaning. The cleaning tank 1 is the core container for lobster cleaning, providing space for the operation of the brush rollers 2 and the operation of the cleaning and filtration mechanism 3, and at the same time holding the cleaning water and the lobsters to be cleaned.

[0038] Specifically, when the lobster cleaning equipment is working, clean water is first injected into the cleaning tank 1 and lobsters are put in. The cleaning and filtration mechanism 3 provides power to the brush roller 2, which rotates to brush the mud and sand on the surface of the lobsters. After cleaning, the cleaning and filtration mechanism 3 separates the lobsters from the water through related structures. After multiple batches of cleaning, the water discharge and mud removal mechanism 4 discharges the sewage and cleans the mud and sand at the bottom of the tank, completing the overall cleaning process.

[0039] The cleaning and filtration mechanism 3 includes a support plate 31, which is externally fixedly connected to the outside of the cleaning tank 1. A braking assembly 32 is provided on the top of the support plate 31. The support plate 31 provides a stable mounting base for the motor 321, ensuring that it does not shake during operation. The braking assembly 32 converts the power of the motor 321 into the rotational power of the brush roller 2. Two strip-shaped grooves 33 are opened on both sides inside the cleaning tank 1. The strip-shaped grooves 33 provide a trajectory guide for the sliding of the manual baffle 35 and restrict its movement in the vertical direction. Two limiting strips 34 are fixedly connected inside the two strip-shaped grooves 33. The manual baffle 35 is slidably connected to the outside of the limiting strips 34. The limiting strips 34 further constrain the sliding range of the manual baffle 35 and prevent it from deviating or falling out of the groove during sliding. Two cylinders 36 are fixedly connected inside the cleaning tank 1. A connecting block 37 is fixedly connected to the drive end, and a telescopic rod 38 is fixedly connected to the outside of the connecting block 37. A filter screen 39 is fixedly connected to the drive end of the telescopic rod 38. The length of the telescopic rod 38 can be flexibly adjusted to ensure that the filter screen 39 can extend into the cleaning area to receive the lobsters. The filter screen 39 is slidably connected to the outside of the manual baffle 35. The connecting block 37 transmits the driving force of the cylinder 36 to the telescopic rod 38 to achieve linkage between the two. The cylinder 36 provides driving force for the rise and fall of the filter screen 39. The filter screen 39 is used to receive the lobsters after cleaning and filters water through the mesh to achieve shrimp-water separation. Handles are provided on both sides of the outside of the manual baffle 35. The outside of the handles is slidably connected to the inside of the strip-shaped chute 33. When cleaning, the manual baffle 35 is at the upper end to close the cleaning area and prevent the lobsters from jumping out. After cleaning, it slides to the lower end to provide a channel for the filter screen 39 to extend in.

[0040] Specifically, when the cleaning and drying mechanism 3 is working, the support plate 31 fixes the motor 321, and the braking component 32 transmits its power to the brush roller 2. During cleaning, the manual baffle 35 is in the upper closed area under the constraint of the strip groove 33 and the limiting strip 34. After cleaning, it slides down to the lower end. The cylinder 36 drives the telescopic rod 38 through the connecting block 37, so that the filter screen 39 extends into the lobster and rises. The shrimp and water are separated through the mesh. The hand grip makes the baffle operation convenient.

[0041] The braking assembly 32 includes a motor 321, the bottom of which is fixedly connected to the top of the support plate 31, and the outside of which is fixedly connected to the outside of the cleaning tank 1. The motor 321 provides stable rotational power. A worm gear 322 is fixedly connected to the drive end of the motor 321. Multiple worm wheels 323 are rotatably connected inside the cleaning tank 1. The outside of the worm wheels 323 and the outside of the worm gear 322 are meshed with each other. The worm gear 322 transmits the rotational power of the motor 321 to the worm wheel 323 to realize power steering and speed adjustment. The worm wheel 323 transmits the power of the worm gear 322 to the brush roller 2, driving it to rotate synchronously. The outside of the worm wheel 323 is fixedly connected to the brush roller 2, and the outside of the brush roller 2 is slidably connected to the outside of the manual baffle 35.

[0042] Specifically, when the braking assembly 32 is working, the motor 321 outputs rotational power, which drives the worm 322 to rotate. The worm 322 transmits power to the worm wheel 323 through meshing and transmission, and adjusts the speed and direction. Finally, the worm wheel 323 drives the brush roller 2 to rotate synchronously, and the brush roller 2 can slide along the manual baffle 35 to complete the power transmission for brushing the lobster.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The water discharge and sludge removal mechanism 4 includes a water discharge and sludge removal piston 41, which is externally slidably connected to the inside of the bottom side of the cleaning tank 1. The water discharge and sludge removal piston 41 is used to control the opening and closing of the sludge discharge port at the bottom of the cleaning tank 1. When opened, it can discharge sewage and sludge, and when closed, it ensures the sealing of the cleaning tank 1. A second motor 42 is fixedly connected to the outside of the bottom side of the cleaning tank 1. A transmission disc 48 is fixedly connected to the drive end of the second motor 42. The second motor 42 provides power for the reciprocating motion of the scraper 47. A protruding shaft 43 is fixedly connected to the outside of the transmission disc 48. The protruding shaft 43 converts the circumferential motion of the transmission disc 48 into the motion of the first transmission link 44. The transmission disc 48 converts the rotational motion of the second motor 42 into the circumferential motion of the protruding shaft 43, providing a basis for subsequent linkage transmission. The protruding shaft 43... The external rotatable connection is a transmission connecting rod 44, and the other end of the external rotatable connection of the transmission connecting rod 44 is a transmission connecting plate 45. The transmission connecting rod 44 drives the transmission connecting plate 45 to move. The internal fixed connection of the cleaning tank 1 is two limiting blocks 46. The external slidable connection of the transmission connecting plate 45 is inside the limiting blocks 46. The external fixed connection of the transmission connecting plate 45 is a scraper 47. The limiting blocks 46 constrain the movement trajectory of the transmission connecting plate 45, ensuring that it only slides back and forth in the horizontal direction to avoid deviation. The transmission connecting plate 45 converts the swing motion of the connecting rod into horizontal reciprocating motion, driving the scraper 47 to move. The external slidable connection of the scraper 47 is inside the bottom side of the cleaning tank 1. The scraper 47 scrapes the mud and sand at the bottom of the tank to the sludge discharge port through reciprocating sliding, realizing the centralized cleaning of mud and sand.

[0044] Specifically, when the water discharge and sludge removal mechanism 4 is working, the second motor 42 outputs power to drive the transmission disc 48 to rotate, causing the protruding shaft 43 to make a circular motion, which in turn drives the transmission connecting plate 45 through the first transmission connecting rod 44 to make a horizontal reciprocating motion under the constraint of the limit block 46, driving the scraper 47 to scrape the mud and sand at the bottom of the pool to the sludge discharge port, and finally opening the water discharge and sludge discharge piston 41 to discharge sewage and mud and sand, thus completing the sludge removal and sewage discharge.

[0045] The implementation principle of this application embodiment is as follows: an appropriate amount of cleaning water is injected into the cleaning tank 1, and then the lobsters to be cleaned are poured into the cleaning tank 1 through the top opening. At this time, the manual baffle 35 is in the uppermost position. The motor 321 is started to drive the worm 322 to rotate. Since the worm 322 is meshed with multiple worm wheels 323, the rotation of the worm 322 will synchronously drive all the worm wheels 323 to rotate, thereby driving multiple brush rollers 2 to rotate synchronously. The rotating brush rollers 2 will drive the water flow in the cleaning tank 1 to form a slight vortex, so that the lobsters will continuously roll and move in the cleaning area, ensuring that the lobster's abdomen, claw gaps, and shell folds can fully contact the brush, effectively removing surface mud and impurities.

[0046] After cleaning is completed, turn off the motor and pull out the drain and mud discharge piston 41 from the bottom to drain the pool water. Manually push the manual baffle 35 so that it slides to the bottom along the constraint of the limit bar 34 in the strip chute 33. At this time, the filter screen 39 is extended into the cleaning pool 1 through the telescopic rod 38 so that it reaches between the crayfish and the brush roller 2 to receive all the cleaned crayfish. Then, start the cylinder 36 to push the connecting block 37, the telescopic rod 38 and the filter screen 39 to rise together. The mesh of the filter screen 39 will filter out the water attached to the surface of the crayfish. The water flows back into the cleaning pool 1, realizing the separation of crayfish and cleaning water, and completing the cleaning process.

[0047] After multiple batches of lobsters have been cleaned, mud and sand will accumulate on the bottom of the cleaning tank 1. Start the motor 2 42, and its drive end will drive the transmission disc 48 to rotate clockwise. The protruding shaft 43 on the transmission disc 48 will move in a circular motion with the transmission disc 48, which will in turn pull the transmission connecting rod 1 44 to swing back and forth. The transmission connecting rod 1 44 will drive the transmission connecting plate 2 45 to move horizontally reciprocating under the constraint of the limit block 46. The scraper 47, which is fixedly connected to the transmission connecting plate 2 45, will slide back and forth synchronously, scraping the mud and sand on the bottom of the cleaning tank 1 to the mud discharge port in the middle of the tank bottom. Manually open the drain and mud discharge piston 41, and the sewage in the cleaning tank 1 will carry the mud and sand scraped by the scraper 47 and be discharged from the mud discharge port.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
