Description

Technical Field

[0001] This utility model relates to the field of grain processing material suction, and in particular to a suction and pickup device for grain processing. Background Technology

[0002] Grains are the products of threshing seeds or fruits of crops, such as corn, vegetables, and flowers. They are usually small in size and light in weight, and easily fall to the ground or even get buried in soil cracks after ripening. The suction device is mainly used to collect these small and easily scattered grains, solving the problems of low efficiency and poor collection effect of traditional collection methods.

[0003] The suction device uses a vacuum pump or fan to draw air, creating negative pressure inside the suction nozzle or suction cup to generate strong suction force, which picks up and collects the grains from the soil or crop residues. The grains then enter the collection bin or packaging bag, completing the suction operation, improving grain collection efficiency and yield, and reducing waste.

[0004] In existing technologies, the grain collection process lacks screening and cleaning functions, resulting in unseparated impurities such as sand, dust, and broken stems being directly mixed into the grains, causing a decrease in grain purity and making them prone to mold or insect infestation during storage. This leads to additional processing steps for the grains. Therefore, a grain collection device for grain processing is proposed to solve the above problems. Utility Model Content

A collection box 2 is fixedly connected to the top of the trolley 1. A sealed door is provided on the front side of the collection box 2 to facilitate the placement and removal of the screening frame 7, improving the convenience of loading, unloading and internal cleaning of the screening frame 7. A discharge port sealed by a sealing plug is provided on one side for the discharge of grains, realizing the centralized export of the screened grains. The sealing plug can prevent the grains from leaking out. A suction pump 3 is fixedly connected to the top of the trolley 1. A telescopic pipe 4 is fixedly connected to the input end of the suction pump 3, which can flexibly adjust the suction range to adapt to different working scenarios. A suction cover 5 is fixedly connected to the end of the telescopic pipe 4. A discharge pipe 6 is fixedly connected to the output end of the suction pump 3. A screening frame 7 is provided inside the collection box 2 to perform size classification screening of the grains. A support leg 8 is fixedly connected to the bottom of the screening frame 7. A support frame 26 is fixedly connected to the inner wall of the collection box 2 to provide an installation carrier for components such as the movable frame 12.

[0034] Reference Figures 3-5 A through groove 9 is provided on the surface of the support frame 26 to provide spatial guidance for the sliding of the movable frame 12. A slide rod 10 is fixedly connected to the inner wall of the through groove 9, and a spring 11 is fixedly connected to the inner wall of the through groove 9. The spring 11 is sleeved on the outer wall of the slide rod 10 to provide a restoring elastic force for the movable frame 12, thereby realizing the reciprocating vibration of the screening frame 7. The end of the spring 11 is fixedly connected to the movable frame 12. The inner wall of the movable frame 12 is slidably connected to the inner wall of the slide rod 10. A slot 13 is provided on the top of the movable frame 12. The inner wall of the slot 13 is inserted into the outer wall of the support leg 8. A motor 14 is fixedly connected to the outer wall of the collection box 2. A rotating shaft 15 is fixedly connected to the output end of the motor 14. The rotating shaft 15 passes through one side of the outer wall of the collection box 2 and is rotatably connected to the inner wall of the collection box 2. An eccentric wheel 16 is fixedly connected to the outer wall of the rotating shaft 15. The eccentric force is generated by the rotation, which drives the screening frame 7 to vibrate.

[0035] Reference Figures 2-4 The top of the collection box 2 is equipped with a cleaning assembly, which includes a cleaning cover 17, a fixing pipe 18, an air pump 20, and a storage box 19. The cleaning cover 17 penetrates the top of the collection box 2 and is fixedly connected to the inner wall of the collection box 2 to form a directional suction channel for collecting light impurities. The inner wall of the cleaning cover 17 is fixedly connected to the fixing pipe 18, and the end of the fixing pipe 18 is fixedly connected to the air pump 20. The output end of the air pump 20 is fixedly connected to the storage box 19 through a pipe. The bottom of the storage box 19 is fixedly connected to the top of the trolley 1.

[0036] Reference Figure 6The side wall of the screening frame 7 is provided with a rectangular groove 21. A magnetic ring 22 is fixedly connected to the inner wall of the rectangular groove 21. A magnetic block 23 is magnetically connected to the inner wall of the magnetic ring 22. A rubber block 24 is fixedly connected to the outer wall of the magnetic block 23. An inclined surface 25 is provided on the outer wall of the rubber block 24 near the eccentric wheel 16. The inclined surface 25 provides a guiding path for the eccentric wheel 16 when it rotates, so that the eccentric wheel 16 can smoothly push the screening frame 7, reduce movement jamming, and the rubber block 24 can reduce the impact wear of the eccentric wheel 16 on the screening frame 7, extend the service life of the screening frame 7, and reduce equipment maintenance costs.

[0037] Working principle: During the grain collection stage, the suction pump 3 is started, and the suction hood 5 at the end of the telescopic pipe 4 generates suction to draw in the external grains and transport them through the discharge pipe 6 to the screening frame 7 inside the collection box 2, achieving initial collection of the grains and allowing them to enter the screening process. The motor 14 drives the rotating shaft 15 to drive the eccentric wheel 16 to rotate continuously. When the eccentric wheel 16 rotates to contact the rubber block 24 on the side wall of the screening frame 7, the inclined surface 25 of the rubber block 24 provides a guide path for the eccentric wheel 16, causing the eccentric wheel 16 to push the screening frame 7 to move. At this time, the support leg 8 at the bottom of the screening frame 7 is inserted into the slot 13 of the moving frame 12. The moving frame 12 slides along the slide rod 10 in the through groove 9 and compresses the spring 11. When the eccentric wheel 16 disengages from the rubber block 24, the rebound force of the spring 11 drives the moving frame 12 to reset, thereby causing the screening frame 7 to sway back and forth with the moving frame 12, utilizing... The screening of grains is achieved by the vibration of the screening frame 7. Smaller grains fall through the holes of the screening frame 7, while larger impurities remain inside the screening frame 7. The rubber block 24 is magnetically connected to the magnetic ring 22 in the rectangular groove 21 on the side wall of the screening frame 7 through the magnetic block 23. This ensures a stable connection with the screening frame 7 and reduces wear caused by the impact of the eccentric wheel 16. The magnetically fixed rubber block 24 is easy to position and replace. At the same time, the cleaning components operate synchronously. The air pump 20 generates negative pressure in the cleaning hood 17 through the fixed pipe 18. Light impurities generated during the screening process, such as dust, debris, stems, weeds, and broken husks, are sucked into the cleaning hood 17 and transported to the storage box 19 through the pipeline for collection, thus separating the grains from the light impurities. Throughout the process, the trolley 1 provides stable support for each component, and the various structures work together to complete the efficient collection, screening, and impurity cleaning of the grains.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
