[0037] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] A preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, a grain collector for rice appearance detection includes an absorber that uses suction to collect rice. The overall structure of the absorber is similar to that of a vacuum cleaner. Specifically, the absorber has a housing 1, inside which is a fan assembly 2 that provides suction, a filter assembly 3 that isolates and filters rice and dust, a collection assembly 4 that collects rice, and a suction nozzle assembly 5 that works with the detector to absorb rice.

[0043] Furthermore, refer to Figure 8 and Figure 10The collection assembly 4 includes a collection box 41, within which a collection tube 42 is formed, its inner diameter gradually decreasing from bottom to top. An air inlet 43, which cooperates with the filter assembly 3, is formed on the collection box 41. The collection assembly 4 also includes a collection cover 14 connected to the housing 1 and a collection cavity 15 formed on the housing 1, with the collection box 41 located within the collection cavity 15. The air inlet 43 can be located on the top of the collection box 41, coaxially arranged with the collection tube 42, or it can be located on the side wall of the collection box 41. When the air inlet 43 is located on the side wall of the collection box 41, the height of the collection tube 42 should not exceed the axis of the air inlet 43. When the air inlet 43 is located on the top of the collection box 41, the height of the collection tube 42 can be appropriately increased, but there should be a gap between it and the top of the collection box 41. By utilizing the combination of the collecting pipe 42 and the air inlet 43, the rice moves upward from the bottom of the collecting box 41 along the collecting pipe 42 under the action of suction. As the inner diameter of the collecting pipe 42 decreases, the rice will fall directly to the bottom of the collecting box 41 after flowing out of the collecting pipe 42, thus collecting the rice in the collecting box 41.

[0044] Furthermore, refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 The fan assembly 2 includes an air duct 21 and an impeller 22 connected to the air duct 21. The filter assembly 3 includes a filter grille 31 connected to the end of the air duct 21 and a filter screen 32 connected to the filter grille 31. The filter screen 32 is mainly used to prevent dust or rice debris carried during the rice absorption process from entering the impeller 22. The air inlet 43 in the collection box 41 is side-mounted, and there is a connector 44 between the collection box 41 and the filter screen 32 that mates with the air inlet 43.

[0045] Furthermore, refer to Figure 8 , Figure 9 The collection box 41 is cylindrical, and the connector 44 has a fitting part 441 that wraps around the collection box 41 and a receiving part 442 that covers the filter screen 32. An air-guiding channel 443, which mates with the air inlet 43, is formed between the fitting part 441 and the receiving part 442. Multiple guide rails 411 extending axially are formed on the outer wall of the collection box 41, and a guide groove 444 that mates with the guide rails 411 is formed on the connector 44. Alternatively, the guide groove 444 can be provided on the collection box 41, in which case the guide rails 411 are provided on the connector 44. The cooperation of the guide groove 444 and the guide rails 411 facilitates the connection between the collection box 41 and the connector 44, and also facilitates the removal and installation of the collection box 41, thereby enabling timely removal of the rice collected in the collection box 41. The structural design of the connector 44 can fully cover the air inlet 43, preventing air leakage at the connection between the connector 44 and the collection box 41, thereby ensuring sufficient suction to draw the rice into the collection box 41.

[0046] Furthermore, refer to Figure 10 , Figure 11 The suction nozzle assembly 5 includes an air guide 51 that connects to the collection tube 42 and a suction head 52. The outer peripheral wall of the end of the air guide 51 has a connecting sleeve 53 that mates with the collection tube 42. Specifically, the connecting sleeve 53 is a silicone sleeve or a rubber sleeve. Multiple annular protrusions 54 are formed on the inner peripheral wall of the connecting sleeve 53, spaced apart along its axial direction. An annular groove 55 that mates with the annular protrusions 54 is formed on the air guide 51. The annular protrusions 54 may also be located on the air guide 51, and the annular groove 55 may be located on the connecting sleeve 53. The connecting sleeve 53 can improve the tightness of the connection between the air guide 51 and the collection tube 42, preventing air leakage at the connection point, and can also prevent the collection box 41 from falling off.

[0047] Furthermore, the suction head 52 includes a flat absorption section 521 and a mating section 522 connected to the air duct 51. The edge of the absorption section 521 has an adhesive strip 523 made of rubber or silicone. The size of the absorption section 521 can be the same as the plane size of the scanner. The adhesive strip 523 is used to cover the entire scanner with the entire suction head 52, thereby increasing the area for absorbing rice. The adhesive strip 523 can also form a seal, thereby effectively ensuring the suction power of the absorber.

[0048] Furthermore, the housing 1 has a handle 11, and the bottom of the housing 1 has auxiliary wheels 12. When the size of the scanner is large, the suction head 52 cannot cover the entire plane. The auxiliary wheels 12 can be used to make the absorber move on the scanner, thereby improving the absorption efficiency and the portability of the absorber.

[0049] Furthermore, the housing 1 has an auxiliary light 13, which is connected to the suction nozzle assembly 5. The light makes it easier to observe and prevents rice from being missed.

[0050] In addition to being used for rice absorption during rice detection, the absorber in this invention can also be used for other large particles that need to be collected, such as grains like corn, wheat, and peanuts, or granular foods like cat food and dog food. Its applications can also be expanded in other ways.

[0051] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0052] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0053] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
