Description

Technical Field

[0001] This invention belongs to the field of aquatic product sorting technology, and specifically relates to an adjustable width conveyor for non-destructive sorting of aquatic products. Background Technology

[0002] Existing aquatic product sorting and conveying equipment, especially for sorting fish and other aquatic products, typically suffers from the following problems: First, the width of the conveyor is fixed, making it difficult to adapt to the conveying needs of fish of different sizes and batches, resulting in poor versatility and high costs and low efficiency when replacing equipment of different sizes; Second, after use, the conveyor belt is prone to leaving impurities such as fish scales and mucus, which, if not cleaned in time, can easily breed bacteria and contaminate subsequent products, and most existing equipment lacks convenient and efficient automatic cleaning functions; Third, the overall structure of the device is fixed, making it difficult to adapt to the placement requirements of different sites (such as narrow front and wide back, uneven ground, etc.), and it is also inconvenient for storage and transportation. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable width conveyor for non-destructive sorting of aquatic products. Its advantages are that the distance between the rotating shafts can be adjusted to accommodate conveyor belts of different widths for fish of different sizes. During disassembly, the conveyor belt can be quickly replaced using the incompletely extended drive shaft, improving versatility and ease of maintenance. At the same time, the surface of the conveyor belt can be cleaned after transportation to avoid bacterial contamination.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An adjustable-width conveyor for non-destructive sorting of aquatic products includes a support frame. The support frame integrates a main conveyor mechanism, a sorting mechanism, an adjustable-width secondary conveyor mechanism, a cleaning mechanism, and a support and adjustment mechanism.

[0005] The main conveying mechanism includes a first drive motor fixedly installed on a load-bearing frame and a first conveyor belt driven by the first drive motor, used to carry and convey aquatic products to be sorted.

[0006] The sorting mechanism includes at least one sorting screw disposed within the inner cavity of the support frame and located above the first conveyor belt, and a sorting drive assembly for driving the sorting screw to rotate. The rotation of the sorting screw can sort aquatic products of different sizes from the first conveyor belt to different areas.

[0007] The adjustable width secondary conveyor mechanism is symmetrically arranged on the front side of the load-bearing frame. It includes two movable frames that can slide along the load-bearing frame, a width adjustment assembly for driving the two movable frames to move synchronously relative to or opposite to each other to adjust the spacing, and a second conveyor belt tensioned between the two movable frames and driven by a second drive motor. By adjusting the spacing of the movable frames, second conveyor belts of different widths can be quickly replaced and adapted.

[0008] The cleaning mechanism is located on the front side of the load-bearing frame. It includes a first cleaning roller and a second cleaning roller that are in contact with the surfaces of the first conveyor belt and the second conveyor belt, respectively, and a cleaning drive assembly that drives the first cleaning roller and the second cleaning roller to rotate, for automatically cleaning the surface of the conveyor belt during or after conveying.

[0009] The support adjustment mechanism includes mounting brackets fixedly installed on both sides of the bottom of the load-bearing frame, and support components set on each mounting bracket that can adjust the support position and support angle relative to the load-bearing frame to adapt to different ground environments and facilitate folding and storage when not in use.

[0010] Preferably, the sorting drive assembly includes a second drive motor fixedly mounted on the inner wall of the support frame, and the output shaft of the second drive motor is connected to the sorting screw via a transmission belt. Furthermore, all sorting drive assemblies can be housed within a removable waterproof housing, which is snapped onto the support frame to provide waterproof protection.

[0011] Preferably, the width adjustment assembly includes a mounting shell fixedly mounted on a load-bearing frame. Inside the mounting shell is a bidirectional threaded rod driven by a third drive motor. Each end of the bidirectional threaded rod is threadedly connected to a threaded sleeve, and the bottom of each threaded sleeve is fixedly connected to a movable frame. The distance between the two movable frames can be precisely controlled by the forward and reverse rotation of the third drive motor. To enhance sliding stability, a limit rod is also slidably connected between the two movable frames, with both ends of the limit rod fixed to the load-bearing frame.

[0012] Preferably, the cleaning mechanism further includes a limiting shell, in which the first and second cleaning rollers are rotatably disposed. The cleaning drive assembly is a fifth drive motor mounted on both sides of the limiting shell, with its output ends connected to the first and second cleaning rollers respectively. To maintain the cleaning effect of the cleaning rollers, two scrapers are also fixedly installed inside the limiting shell, with the front sides of the two scrapers contacting the surfaces of the first and second cleaning rollers respectively to scrape off impurities adhering to their surfaces.

[0013] Preferably, the support assembly includes a positioning threaded rod rotatably connected to both sides of the inner cavity of the mounting frame, a threaded sleeve threadedly connected to the positioning threaded rod, and a positioning frame rotatably connected to the threaded sleeve. A load-bearing shell is fixed to the bottom of the positioning frame, and a hydraulic rod is provided inside the load-bearing shell. A retractable load-bearing rod is connected to the bottom of the hydraulic rod. The lateral distance between the two support points can be adjusted by rotating the positioning threaded rod, and the tilt angle of the load-bearing frame can be adjusted by independently controlling the hydraulic rods on both sides. Furthermore, a positioning rod is slidably connected between the two threaded sleeves, and both ends of the positioning rod are fixed to the mounting frame to ensure smooth movement of the threaded sleeves. Positioning blocks can also be detachably engaged at both ends of the inner cavity of the mounting frame. The positioning blocks engage with the ends of the positioning threaded rod to limit accidental rotation and enhance stability.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The motor three, bidirectional threaded rod and movable frame in the installation component can be used to adjust the distance between the rotating shafts to adapt to the width of the conveyor belt two and the needs of conveying fish of different sizes. At the same time, by using the incompletely extended drive shaft three, the conveyor belt two can be quickly replaced without disassembling the installation component, which greatly reduces the difficulty of maintenance and improves the efficiency of maintenance. The support component can flexibly adjust the distance between the load-bearing rods and the support angle to adapt to different placement environments such as front narrow and back wide, back wide and front narrow, and can be quickly folded and stored for easy transportation and storage. 2. Achieve non-destructive sorting and automatic cleaning, ensuring the quality of aquatic products and reducing labor intensity: Through the cooperation of motor two, transmission shaft two and sorting screw in the sorting component, the aquatic products are automatically and non-destructively sorted without human contact, avoiding damage to aquatic products caused by manual sorting and improving sorting efficiency. The cleaning component can automatically wipe and clean conveyor belt one and conveyor belt two, and remove impurities from the surface of the cleaning roller with the help of scrapers, effectively preventing bacterial growth and preventing aquatic product contamination. At the same time, manual cleaning is not required, reducing the intensity of manual labor. Each motor is equipped with a waterproof and dustproof protective structure to extend the service life of the equipment and ensure long-term stable operation of the device.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0018] refer to Figures 1-4 This embodiment provides an adjustable-width conveyor for non-destructive sorting of aquatic products, which includes a support frame 1. The support frame 1 is equipped with a main conveying mechanism, a sorting mechanism, an adjustable-width secondary conveying mechanism, a cleaning mechanism, and a support and adjustment mechanism.

[0019] Specifically, the main conveying mechanism includes a motor 2 fixedly installed on the rear left side of the support frame 1. Rotating shafts 3 are rotatably connected to both the front and rear sides of the inner cavity of the support frame 1. The output end of the first drive motor 2 passes through the support frame 1 and is fixedly connected to the rotating shaft 3 located on the rear side. A conveyor belt 5 is fitted and tensioned between the surfaces of the two rotating shafts 3. When the first drive motor 2 is working, it drives the first conveyor belt 5 to circulate through the rotating shafts 3, which is used to carry and transport the aquatic products to be sorted forward.

[0020] The sorting mechanism is located within the inner cavity of the support frame 1 and above the first conveyor belt 5. In this embodiment, the sorting mechanism includes multiple sorting screws 604 arranged along the conveying direction. Both ends of each sorting screw 604 are rotatably connected to the inner wall of the support frame 1 via bearings. The sorting drive assembly that drives the sorting screws 604 includes a second motor 601 fixedly installed on the inner wall of the support frame 1. A second drive shaft 602 is fixedly connected to the output end of the second drive motor 601. Pulleys are installed on the second drive shaft 602 and the ends of each sorting screw 604, and they are linked by one or several synchronous drive belts 603, allowing one second drive motor 601 to drive all sorting screws 604 to rotate synchronously.

[0021] To protect the drive components, all motors 601, transmission belts 603, and pulleys are covered by a detachable waterproof shell 605. This waterproof shell 605 is detachably connected to the load-bearing frame 1 via clips or bolts for easy maintenance. The rotation of the sorting screw 604, utilizing the gap between its spiral blades and the surface of the first conveyor belt 5, enables the orderly diversion and sorting of fish of different sizes, achieving non-destructive automated sorting.

[0022] The adjustable width conveying mechanism is symmetrically arranged on the front side of the load-bearing frame 1. It includes two symmetrically arranged movable frames 705, the bottoms of which are slidably connected to a slide rail on the front side of the load-bearing frame 1 via sliders. The width adjustment assembly that drives the two movable frames 705 to move synchronously towards or away from each other includes a mounting housing 701 fixedly installed on the front side of the load-bearing frame 1. A bidirectional threaded rod 703 is horizontally arranged inside the mounting housing 701, and this bidirectional threaded rod 703 is driven to rotate by a motor 702 fixed to the mounting housing 701. A threaded sleeve 704 is threadedly connected to the left-hand and right-hand threaded sections of the bidirectional threaded rod 703, and the bottom of each threaded sleeve 704 is fixedly connected to one of the movable frames 705. To increase sliding stability, a limiting rod 709 is also provided between the two movable frames 705, and both ends of the limiting rod 709 are fixed to the load-bearing frame 1.

[0023] Starting motor 3 702 drives the bidirectional threaded rod 703 to rotate, thereby precisely controlling the distance between the two movable frames 705. Each movable frame 705 is equipped with motor 4 706, whose output shaft is connected to drive shaft 3 707. The other side of each movable frame 705 is rotatably connected to a limit shaft 708. Conveyor belt 2 8 is tensioned and fitted onto the drive shaft 3 707 and the limit shaft 708 of both movable frames 705. By adjusting the distance between the movable frames 705, second conveyor belts 8 of different widths can be installed. When the distance is not extended to its limit, the second conveyor belt 8 can be quickly fitted or removed without complete disassembly, facilitating replacement.

[0024] The cleaning mechanism is fixedly installed on the front side of the support frame 1. It includes a limiting shell 901, inside which cleaning roller 1 903 and cleaning roller 2 904 are rotatably mounted. The position of cleaning roller 903 contacts the working surface of the second conveyor belt 8, and the position of cleaning roller 904 contacts the working surface of the first conveyor belt 5. The cleaning drive assembly that drives the cleaning rollers consists of two fifth drive motors (marked as motor 5 902 in the figure) respectively installed on both sides of the limiting shell 901, whose output shafts are connected to the shaft ends of cleaning roller 1 903 and cleaning roller 2 904 respectively. To maintain the cleaning effect of the cleaning rollers, two scrapers 905 are fixedly installed on the rear side of the inner cavity of the limiting shell 901. The scrapers 905 can be made of a wear-resistant material with a certain degree of elasticity (such as rubber or polyurethane), and their cutting edges or working surfaces are elastically pressed against the surfaces of the corresponding cleaning roller 1 903 and cleaning roller 2 904 after assembly. As the cleaning rollers rotate, the attached impurities are scraped off by the scraper 905 and fall into the collection tank below or out of the discharge device. When the fifth drive motor 902 is working, it drives the first cleaning roller 903 and the second cleaning roller 904 to rotate, thereby wiping and cleaning the surfaces of the first conveyor belt 5 and the second conveyor belt 8.

[0025] The support and adjustment mechanism is used to support and level the entire device. It includes mounting brackets 1001 fixedly installed on both sides of the bottom of the load-bearing frame 1. Each mounting bracket 1001 is provided with a set of support components 10.

[0026] When in use, first adjust the support adjustment mechanism according to the ground conditions, adjust the lateral spacing of the two load-bearing rods 1007 by rotating the positioning threaded rod 1002, then adjust the horizontal or required tilt angle of the device by the hydraulic rod 1006, and lock it with the positioning block 1010.

[0027] Then, based on the size of the aquatic products to be sorted, the distance between the two movable frames 705 is adjusted by the third drive motor 702, and a second conveyor belt 8 of corresponding width is installed. The first drive motor 2, the second drive motor 601, and the fourth motor 706 are started to drive the first conveyor belt 5, the sorting screw 604, and the second conveyor belt 8 to operate, respectively.

[0028] An external water source supplies water to the water storage tank 11, wetting the first conveyor belt 5. Aquatic products are placed on the first conveyor belt 5. During transport, the rotating sorting screw 604 sorts the fish into different areas according to their size, ultimately dropping them onto the second conveyor belt 8 for output. During or after operation, the fifth drive motor 902 of the cleaning mechanism can be activated to drive the cleaning rollers 903 and 904 to automatically clean the two conveyor belts, while the scraper 905 removes dirt from the surface of the cleaning rollers. Example 2

[0029] This embodiment, based on embodiment 1, further describes in detail the support adjustment mechanism and the water storage shell 11.

[0030] refer to Figure 1 , Figure 5 and Figure 6 The specific structure of the support assembly 10 is as follows: A positioning threaded rod 1002 is rotatably connected to both sides of the inner cavity of each mounting bracket 1001 via bearings. A threaded sleeve 1003 is threadedly connected to each positioning threaded rod 1002. A positioning bracket 1004 is rotatably connected to the top of the threaded sleeve 1003 via a rotating shaft. A positioning rod 1009 slides through the inner holes of the two threaded sleeves 1003. The two ends of the positioning rod 1009 are fixed to the mounting bracket 1001 to prevent the threaded sleeves 1003 from rotating with the positioning threaded rods 1002, ensuring that they only perform linear motion. A load-bearing shell 1005 is fixed to the bottom of the positioning bracket 1004. A hydraulic rod 1006 (or other linear drive mechanism, such as an electric push rod) is fixedly installed inside the load-bearing shell 1005. The bottom output end of the hydraulic rod 1006 is connected to a telescopic load-bearing rod 1007. The bottom of the load-bearing rod 1007 passes through the load-bearing shell 1005 and is equipped with a buffer pad 1008 (such as a rubber pad).

[0031] In addition, positioning blocks 1010 are detachably engaged at both ends of the inner cavity of the mounting bracket 1001. When it is not necessary to adjust the support width, the positioning blocks 1010 can be inserted to engage with the end of the positioning threaded rod 1002, thereby locking the positioning threaded rod 1002 and preventing it from rotating accidentally.

[0032] The support adjustment and folding process is as follows: 1. When the width of the ground is limited or the center of gravity needs to be adjusted, the positioning block 1010 can be pulled out, and then the positioning threaded rod 1002 can be rotated. The rotation of the positioning threaded rod 1002 drives the two threaded sleeves 1003 to slide towards or away from each other along the positioning rod 1009, thereby causing the two positioning frames 1004 and the load-bearing rod 1007 below to change the spacing to adapt to special sites such as narrow front and wide back.

[0033] 2. When the ground is uneven, the hydraulic rods 1006 on both the front and rear sides of the load-bearing frame 1 can be controlled independently. By keeping the length of one hydraulic rod 1006 constant and extending or retracting the hydraulic rod 1006 on the other side, the tilt angle of the load-bearing frame 1 can be changed, thus achieving leveling.

[0034] 3. When the equipment needs to be transported or stored, the hydraulic rod 1006 can be retracted to its shortest length first. Then, using the rotational connection point between the positioning frame 1004 and the threaded sleeve 1003 as the axis, the entire support assembly 10 can be flipped upwards so that it is close to the bottom of the load-bearing frame 1. A magnetic attraction structure is provided at the corresponding position at the bottom of the load-bearing frame 1 (for example, a magnet is installed at the bottom of the load-bearing frame, and an iron plate is installed at the corresponding position on the load-bearing shell 1005 or the positioning frame 1004, or vice versa). When the support assembly 10 is folded into place, it is fixed by magnetic attraction, thereby achieving compact storage.

[0035] Furthermore, as a preferred embodiment, a water storage shell 11 can be fixedly installed on the top rear side of the inner cavity of the load-bearing frame 1. The bottom opening of the water storage shell 11 contacts the upper surface of the conveyor belt 5. The water storage shell 11 can be connected to an external water supply pipe to store a small amount of clean water inside, which continuously moistens the section of the conveyor belt 5 that it contacts at the bottom through capillary action or slight dripping, thereby pre-moistening the conveyor belt area that the fish contacts before sorting, further reducing frictional damage to the fish's skin during transportation.
