Description

Technical Field

[0001] This utility model relates to the technical field of sorting technology, and in particular to a multi-stage sorting mechanism for blueberry packaging. Background Technology

[0002] Blueberries, a round, blue berry, are widely popular for their sweet and sour taste. In commercial processing, large-diameter berries are typically packaged and sold directly as high-end fresh fruit, while smaller-diameter berries are used to process jams and other derivative products. Therefore, after harvesting, blueberries need to be manually sorted according to size, a process that is labor-intensive, costly, inefficient, and prone to significant deviations in sorting standards. Therefore, there is an urgent need for a multi-stage sorting mechanism for blueberry packaging to improve efficiency and reduce costs. Utility Model Content

[0003] This invention provides a multi-stage sorting mechanism for blueberry packaging to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A multi-stage sorting mechanism for blueberry packaging includes an inclined sorting trough, with the height of the inlet end greater than the height of the outlet end, and the height of one trough wall greater than the height of another. Multiple limiting strips are evenly arranged along the length of the trough bottom, with limiting grooves formed between adjacent limiting strips and between the limiting strips near the trough wall and the trough wall. Multiple collection troughs are spaced apart along the width of the trough bottom, with the width of the collection troughs increasing sequentially from the inlet end to the outlet end. The intersection of the collection troughs and the limiting strips forms a sorting opening. An outlet, communicating with the multiple collection troughs, is formed on the lower trough wall. By using multiple limiting strips and multiple collection troughs of different specifications in the sorting trough to form sorting openings of different diameters, and by adjusting the arrangement angle of the sorting trough, automatic sorting of blueberry particles by size is achieved using the principle of gravity.

[0006] Preferably, the width of the limiting groove is greater than the diameter of the largest blueberry particle.

[0007] Preferably, the discharge port is provided with an inclined discharge chute, and a collection box is arranged below the discharge end of both the discharge chute and the sorting chute.

[0008] Preferably, optical detection devices are mounted on the top of the discharge end of both the discharge trough and the sorting trough, and air separators are mounted on the bottom of the discharge end of both. The air separators are connected to a controller that controls their operating status. The optical detection devices include interconnected cameras and signal processing modules, and the signal processing modules are connected to the controller.

[0009] Preferably, the top of the collection box is open, and the interior is divided into a defective product collection area and a good product collection area by a partition. The good product collection area is located directly below the discharge end, and the defective product collection area is located on the side away from the sorting tank.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention combines multiple sets of limiting grooves and collection grooves of different specifications on an inclined sorting trough to form sorting ports of various specifications. When blueberries flow through the limiting grooves by their own weight, they cooperate with the sorting ports of different specifications to achieve automatic particle size classification.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0018] Example 1

[0019] like Figure 1-3 The multi-stage sorting mechanism for blueberry packaging shown includes an inclined sorting trough 1. Specifically, the height of the feed end of the sorting trough 1 is greater than the height of the discharge end, and the height of one trough wall 11 is greater than the height of the other trough wall 11, so that the blueberries fed from the feed end of the sorting trough 1 flow towards the trough wall 11 with the lower height and towards the discharge end under the action of gravity.

[0020] Multiple limiting strips 2 are evenly arranged along the length of the bottom of the sorting tank 1, and limiting grooves 12 are formed between two adjacent limiting strips 2 and between the limiting strip 2 near the tank wall 11 and the tank wall 11. The limiting grooves 12 are used to limit the flow path of blueberries in the sorting tank 1. Taking advantage of the characteristic that the blueberries in the sorting tank 1 always flow towards the discharge end, the blueberries in the limiting grooves 12 also always flow towards the discharge end.

[0021] The bottom of the sorting tank 1 is provided with multiple collection tanks 13 spaced apart along the width direction. The width of the collection tanks 13 increases sequentially from the feed end to the discharge end, so that the part where the collection tanks 13 intersect with the limiting tanks 12 forms a sorting port 14. The diameter of each sorting port 14 increases sequentially from the feed end to the discharge end of the sorting tank 1. When blueberries pass through each sorting port 14 in sequence, according to the size of the sorting port 14 and the size of the blueberry, the blueberries fall into the corresponding collection tank 13 in order from small to large. Blueberries that do not pass through the sorting port 14 and enter the collection tank 13 are discharged from the discharge end of the sorting tank 1, thereby realizing multi-stage sorting of blueberries.

[0022] The lower wall 11 of the trough has a discharge port 15 that communicates with multiple collection troughs 13. The blueberries that enter the collection trough 13 are automatically discharged through the discharge port 15, taking advantage of the characteristic that the blueberries in the sorting trough 1 always flow towards the lower wall 11.

[0023] In practice, blueberries are fed into the limiting groove 12 from the feed end of the sorting groove 1. At this time, the blueberries in the limiting groove 12 flow toward the discharge end of the sorting groove 1. During this process, as the blueberries pass through multiple sorting ports 14 with increasing diameters in sequence, the blueberry particles fall into the corresponding collection grooves 13 in order from small to large. The blueberries that enter the collection grooves 13 are then discharged from the sorting ports 14. The blueberries that do not pass through the sorting ports 14 and enter the collection grooves 13 are discharged from the discharge end of the sorting groove 1, thereby achieving multi-stage sorting of blueberries.

[0024] As a preferred embodiment of the above, the width of the limiting groove 12 is greater than the particle size of the largest blueberry particle, ensuring that the blueberries can flow within the limiting groove 12.

[0025] As a preferred embodiment of the above, the discharge port 15 is provided with an inclined discharge trough 3, and a collection box 4 is arranged below the discharge end of both the discharge trough 3 and the sorting trough 1. Specifically, the height of the inlet end of the discharge trough 3 is greater than the height of the discharge end, so that the blueberries in the collection trough 13 can fall into the corresponding collection box 4 by gravity. During the implementation process, the blueberries sorted by the discharge end of the sorting trough 1 also fall into the corresponding collection box 4 to achieve the collection of sorted blueberries.

[0026] Example 2

[0027] Based on the above embodiments, such as Figure 1 and Figure 4 As shown, optical detection devices 5 are mounted on the top of the discharge end of both the discharge trough 3 and the sorting trough 1, and air separators 6 are mounted on the bottom of the discharge end of both. The air separators 6 are connected to a controller that controls their operation. The optical detection devices 5 include interconnected cameras and signal processing modules. The signal processing module is connected to the controller, which controls the operation of the air separators 6 based on the detection results output by the signal processing module to achieve secondary sorting of the blueberries. The top of the collection box 4 is open, and its interior is divided into a defective product collection area 42 and a good product collection area 43 by a partition 41. The good product collection area 43 is located directly below the discharge end, while the defective product collection area 42 is located on the side away from the sorting trough 1. Specifically, the optical inspection device 5 is the optical inspection system in the color sorter, including an optical inspection mechanism and a signal processing module. During implementation, the signal processing module stores the shape standard of defective blueberries. The camera captures the image information of the blueberries and feeds it back to the signal processing module for comparison with the shape standard of the defective blueberries to determine the quality of the blueberries. When the quality of the blueberries is determined to be defective, the controller starts the air sorter 6 to blow the defective blueberries into the defective product collection area 42, while the good products fall directly into the good product collection area 43 directly below.

[0028] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
