Description

Technical Field

[0001] This utility model relates to the field of aquatic product transportation technology, and in particular to a non-destructive crate conveying system suitable for oysters after weight sorting. Background Technology

[0002] The current mainstream method of loading sorted oysters into crates involves dropping the weighed oysters directly into the crates or allowing them to fall onto a conveyor belt for further movement. This method generates mechanical impact that can easily damage the fragile edges of the oyster shells. Because oyster shells are relatively thin and brittle, whether falling freely from a height into the bottom of the crate or colliding with the rigid structure of the conveyor (such as a mesh belt or metal frame), they are subjected to excessive mechanical contact stress, leading to shell cracks or the appearance of fine cracks.

[0003] On the other hand, the physical damage to oysters during the crating process comes not only from the falls and collisions themselves, but also from positioning errors introduced by manual operation. Due to potential deviations in the position and angle of the crates placed manually, and the uncertainties in the crating process, oysters do not always land directly in the center of the crate during their fall, but often impact the hard edges or corners of the crate walls, causing concentrated impact. At the same time, a lack of coordination between the sorting equipment and the downstream conveyor can also lead to oysters piling up and being squeezed on the production line.

[0004] The aforementioned physical damage (free fall / collision), positioning errors (impact on basket walls), and rhythm mismatch (piling up) cause significant shell damage to oysters during the critical sorting and packing stages. This damage greatly reduces the vitality and survival rate of oysters during subsequent distribution and transportation, resulting in a significant increase in oyster mortality, necessitating urgent optimization.

[0022] Reference Figure 1This utility model provides a non-destructive crating and conveying system suitable for oysters after weight sorting, including a box-type weight sorter, a first underwater lifting conveyor, a second underwater lifting conveyor, a third underwater lifting conveyor, an underwater crating conveyor, and an oyster conveyor; the box-type weight sorter is connected to the first underwater lifting conveyor, the second underwater lifting conveyor, and the third underwater lifting conveyor; the underwater crating conveyor has multiple crating troughs, each crating trough being connected to the first underwater lifting conveyor, the second underwater lifting conveyor, the third underwater lifting conveyor, and the oyster conveyor.

[0023] The non-destructive crating and conveying system of this utility model operates through the following process: Oysters are sorted by weight on a box-type weight sorter and conveyed to a first, second, or third underwater lifting conveyor. The first, second, or third underwater lifting conveyor lifts the oysters to the crating tank in the underwater crating conveyor for crating. The crated oysters are then sent out by the oyster conveyor.

[0024] In this embodiment of the invention, a first weighing device is provided in the hopper-type weight sorting machine. The first weighing device determines the weight range of each oyster, and different sorting outlets are selected according to the weight range of each oyster to transport the oysters to a first, second, or third underwater lifting conveyor. In this embodiment, the first, second, and third underwater lifting conveyors each correspond to different weight ranges to achieve the sorting and crating of oysters of different weights. It should be noted that the number of underwater lifting conveyors can be adjusted according to different weight ranges to achieve sorting; this invention does not limit the specific number of underwater lifting conveyors.

[0025] In this embodiment of the invention, the first / second / third underwater lifting conveyor consists of a conveying trough and a conveyor belt, which transports oysters within a water medium. The underwater lifting conveyor employs a conveyor belt lifting method to ensure stable and continuous underwater feeding and lifting. Specifically, as shown... Figure 2 As shown, the conveying troughs and conveyor belts in the first / second / third underwater lifting conveyors are divided into lifting sections and weighing sections. Weighing equipment is installed in the weighing sections. The inlet of the lifting section is located below the sorting outlet of the hopper-type weight sorter, and the outlet of the weighing section is located above the crating trough of the underwater crating conveyor. Oysters are lifted to the weighing section via the lifting section, where they are weighed by a second weighing device. This invention generates a lifting signal by weighing the oysters in the weighing section and sends it to the underwater crating conveyor, enabling the underwater crating conveyor to transport crates of a fixed weight.

[0026] In some embodiments, the hopper-type weight sorter is also equipped with a vision device to count the number of oysters conveyed by the first, second, and third underwater lifting conveyors.

[0027] In some embodiments, the first / second / third underwater lifting conveyor is further equipped with an adaptive start-stop module; the adaptive start-stop module controls the conveying speed of the conveyor belt according to the sorting signal sent by the hopper-type weight sorter. Through the adaptive start-stop module, the sorting signal from the hopper-type weight sorter is received and the speed is dynamically adjusted to speed up or slow down the oyster loading speed, so as to avoid secondary damage caused by oyster accumulation.

[0028] In this embodiment of the utility model, such as Figure 3 As shown, the underwater crate-filling conveyor includes a crate-filling tank and a conveyor belt. Multiple crates are placed in the crate-filling tank and submerged in water. Oysters are crated using these crates, and the conveyor belt transports the crates to the oyster conveyor. The underwater crate-filling conveyor controls the start of the conveyor belt based on lifting signals sent by the first / second / third underwater lifting conveyor, thus transporting the crates containing oysters to the oyster conveyor.

[0029] In some embodiments, a laser grating sensor is installed in the underwater crate conveyor. The laser grating sensor positions the crates and controls the conveyor belt to position them at the weighing section outlet of the first / second / third underwater lifting conveyor. Through the linkage between the laser grating sensor group and the conveyor belt, high-precision positioning of the crates is achieved, ensuring 100% accurate loading of oysters into the crates.

[0030] In this embodiment of the utility model, an integrated water tank design of an underwater lifting conveyor and an underwater crate conveyor is adopted, so that the oysters are submerged in water throughout the entire process from sorting to crate placement. The water medium buffers and eliminates mechanical collisions from falling, achieving zero physical contact damage to the oysters during the entire crate placement and conveying process, with a shell integrity rate of ≥99%.

[0031] In some embodiments, the crate conveying system of this utility model is constructed using stainless steel lining plates. The inner wall of the water tank is lined with 326 stainless steel lining plates, and the conveyor belt is made of food-grade polypropylene woven mesh belt to avoid seawater corrosion of the equipment and contamination of oysters by residual dirt, thereby extending the equipment life by 3 times and meeting food safety standards.

[0032] This invention achieves the following improvements over existing technologies: Regarding the crating method, traditional dry drop / rigid mesh chain conveying is prone to impact; this solution uses full-process water immersion conveying to buffer the impact. Regarding positioning accuracy, traditional manual positioning errors lead to impacts; this solution uses laser grating sensing + servo braking to achieve positioning. Regarding cycle control, traditional independent sorting and conveying operations are prone to accumulation; this solution uses an adaptive start / stop module to dynamically match the sorting rhythm. Regarding equipment durability, traditional metal parts are prone to corrosion and difficult to clean; this solution uses a food-grade polypropylene mesh belt + 316 stainless steel lining, extending service life. Overall, this invention, through multi-dimensional innovation of "water-based buffering + laser positioning + dynamic cycle control," breaks through the damage bottleneck in oyster sorting and crating, achieving a dual improvement in survival rate and quality, providing technical support for high-value-added oyster products.

[0033] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
