Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example

[0032] Reference Figures 1 to 5 This embodiment provides a fresh food grading vibrating screen that can efficiently screen fresh food of different sizes and shapes. It includes a screening component, a cleaning component, an adjustment component and a driving component. The cleaning screen 2 avoids screen hole clogging and improves screening efficiency.

[0033] Specifically, the screening components include a material frame 1 and a screen 2 set at the bottom of the material frame 1. The material frame 1 serves as a container for fresh ingredients, and the screen 2 can be replaced with screens of different aperture sizes according to the specifications of the fresh ingredients, so as to quickly switch screening levels and flexibly adjust according to actual application needs.

[0034] The cleaning component includes a cleaning box 11 located at the bottom of the screen 2. The cleaning box 11 has a base plate 16 inside. The top surface of the base plate 16 is arrayed with bristles 17 that contact the screen 2. The bristles 17 are made of a flexible material, which can not only effectively remove the attached substances, but also will not damage the screen 2, thus improving its service life.

[0035] The adjustment component includes springs 21 located at the bottom of both ends of the base plate 16 and the inner bottom of the cleaning box 11. Bolts 12, which abut against the springs 21, are threaded through the bottom of the cleaning box 11. The compression of the springs 21 is adjusted by rotating the bolts 12 according to the cleaning intensity requirements, thereby changing the contact force between the bristles 17 and the screen 2 and achieving precise adjustment. At the same time, the bristles 17 work with the springs 21 to extend and retract up and down, forming a continuous impact on the screen holes of the screen 2 during the movement, effectively removing stuck materials, avoiding screen hole blockage, and cleaning more thoroughly, thereby ensuring the screening throughput and continuity.

[0036] The drive assembly includes a lead screw 19 for driving the movement of the cleaning box 11. A reinforcing tube 10 is provided between the middle of the two ends of the material frame 1. The screen 2 is located on the top surface of the reinforcing tube 10. The lead screw 19 is rotatably disposed inside the reinforcing tube 10. A connecting sleeve 20 is threaded on the outer surface of the lead screw 19. The side wall of the reinforcing tube 10 has a hole or groove along its length for the cleaning box 11 to pass through. The end of the cleaning box 11 is connected to the outer wall of the connecting sleeve 20. The rotation of the lead screw 19 drives the connecting sleeve 20 and the cleaning box 11 to move, so that the bristles 17 can move laterally back and forth below the screen 2 to achieve dynamic cleaning without affecting the screening process.

[0037] Furthermore, the inner wall of the material frame 1 is provided with a guide groove 14 along the length direction, and the outer end of the cleaning box 11 is provided with a positioning slider 15. The positioning slider 15 is located inside the guide groove 14 and is slidably connected. The cleaning box 11 and the screen 2 are distributed in parallel, which ensures the stability and alignment of the cleaning box 11 when it moves, and avoids cleaning failure or jamming due to deviation.

[0038] The cleaning box 11 has two parts, which are symmetrically distributed on both sides of the reinforcing tube 10. A handwheel 13 is provided at the end of the lead screw 19. A limit ring 18 is provided at the top of the cleaning box 11. The bristles 17 penetrate the center hole of the limit ring 18. The dual cleaning boxes 11 improve the cleaning efficiency and uniformity. The limit ring 18 is conducive to the limiting installation of the base plate to prevent it from falling out, and at the same time facilitates the replacement of the bristles 17.

[0039] Preferably, one end of the material frame 1 is provided with a downwardly inclined discharge port 3, and the other end is provided with an upwardly inclined feed port 4. A mounting frame 5 is provided below the material frame 1, and a hopper 6 is provided below the screen 2. The inclined structure uses gravity to assist in feeding and discharging, improves material flowability and reduces manual intervention. The hopper 6 is used to collect undersize material for convenient subsequent processing or packaging.

[0040] It should be noted that a crankshaft 9 is rotatably mounted on one end of the mounting frame 5 adjacent to the feed inlet 4. A connecting rod is provided between the crankshaft 9 and the reinforcing tube 10, and the end of the connecting rod is rotatably connected. A motor 8 is mounted on the mounting frame 5 and is connected to the crankshaft 9. A support plate 7 is provided between the material frame 1 and the mounting frame 5. The ends of the support plate 7 are all rotatably connected. The crankshaft 9 is driven by the motor 8 to vibrate the material frame 1.

[0041] In use, fresh ingredients are fed into the feed frame 1 through the inlet 4. The inclined feeding design effectively reduces the impact of falling materials and prevents damage. The motor 8 starts and drives the crankshaft 9 to rotate, causing the feed frame 1 to vibrate through the connecting rod and support plate 7. This causes the ingredients to bounce on the surface of the screen 2, resulting in effective sieving. During the sieving process, smaller ingredients pass through the screen 2 and fall into the hopper 6 below, while larger ingredients slide out along the outlet 3 at the other end of the feed frame 1, achieving automatic grading. At the same time, the handwheel 13 drives the lead screw 19 to rotate, causing the connecting sleeve 20 to move, thereby driving... The two cleaning boxes 11 move, and the bristles 17 of the cleaning box 11 adhere to the surface of the screen 2 under the action of the spring 21 on the bottom surface of the base plate 16. With the horizontal reciprocating motion, the screen is brushed and washed, which effectively avoids screen clogging and ensures the stability of long-term continuous screening operation. The bristles 17 can remove the residue in the screen holes without damaging the screen surface, which is suitable for the grading needs of various ingredients. The cleaning box 11 is stably guided by the positioning slider 15 to ensure that it does not deviate or slip during operation. The structure of the spring 21 and bolt 12 in the adjustment component makes the cleaning pressure adjustable to adapt to different screen materials and thicknesses.

[0042] In summary, the brush bristles 17, supported by the spring 21, possess excellent flexibility and elasticity, allowing them to extend and retract vertically. During movement, they continuously impact the screen openings of the screen 2, effectively removing stuck materials, preventing screen blockage, and ensuring more thorough cleaning. This guarantees the screening throughput and continuity. Simultaneously, the compression degree of the spring 21 can be controlled by adjusting the bolt 12, precisely controlling the cleaning force of the brush bristles. The dual cleaning boxes 11, in conjunction with the guide groove 14 and positioning slider 15, ensure a stable and unwavering cleaning path. With strong adaptability, it is suitable for scenarios with high requirements for hygiene and screening accuracy, such as processing fruits, vegetables, fungi, and root vegetables.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
