For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 8 As shown, an elevator 2 is installed on one side of the frame 1, and the output end of the elevator 2 is adaptably connected to the first vibrating screen 3. A downwardly inclined material sorting device 4 is provided below the first vibrating screen 3, and the lower end of the material sorting device 4 is adaptably connected to the second vibrating screen 5. A storage hopper 8 is provided below the output end of the second vibrating screen 5; a mechanical arm 6 is spaced apart on one side of the material sorting device 4, and the output end of the mechanical arm 6 is fixedly connected to a suction cup mechanism 7, and the width of the suction cup mechanism 7 is equal to the width of the inner side of the material sorting device 4.

[0027] The material sorting device 4 includes a chassis 9, an alignment frame 10, a transverse movement mechanism, a point plate 11, a baffle 12 and a buffer mechanism. The frame 1 is fixed with a chassis 9 tilted downward, and a plurality of through slots 33 are provided on the chassis 9. The chassis 9 is circumferentially covered with an alignment frame 10, and a transverse movement mechanism is provided in the alignment frame 10. The upper end of the transverse movement mechanism is slidably connected with the point plate 11, and baffles 12 are provided on both sides of the point plate 11; the upper end of the point plate 11 is adapted to be connected with the buffer mechanism, and the buffer mechanism is arranged directly below the first vibrating screen 3. The point plate 11 is provided with a plurality of linear and equally spaced point slots 13, and at least three small holes 14 are provided at the bottom of the point slots 13, and the small holes 14 are connected with the alignment frame 10. It also includes a de-impurity fan 25, and the output end of the de-impurity fan 25 is connected with the alignment frame 10 through an air supply pipe inserted into the through slot 33 (the air supply pipe is not shown in the attached drawing, and is a common air supply pipe on the market). When the impurity removal fan 25 is turned on, wind energy can pass through the small holes 14 to remove impurities from the surface of the material in the cavity 13 by wind.

[0028] The suction cup mechanism 7 includes a bracket 15, a vacuum negative pressure generator 16, an air collecting block 17, a connecting piece 18 and a suction nozzle 19. The output end of the robot arm 6 is fixedly connected to the upper end of the bracket 15. A plurality of air collecting blocks 17 are evenly arranged on the bracket 15. The input end of the air collecting block 17 is adaptably connected to the vacuum negative pressure generator 16. The output end of the air collecting block 17 is connected to the suction nozzle 19 through the connecting piece 18. The number of suction nozzles 19 arranged horizontally is equal to the number of grooves 13 arranged horizontally. When there are two materials in the grooves 13, the suction nozzle 19 will only suck away one material, which greatly improves the qualified rate of a single column of materials. The suction nozzle 19 includes an integrally formed suction port 31 and an air collecting pipe 32. The diameter of the suction port 31 is larger than the diameter of the air collecting pipe 32. The air collecting pipe 32 is wavy, which can absorb the material more accurately.

The mounting block 28 is fixed with a slide rail 29, and a slider 30 is slidably connected to the slide rail 29. The upper end of the slider 30 is fixedly connected to the bottom of the acupuncture plate 11. The motor 26 drives the crankshaft 27 to move, so that the acupuncture plate 11 swings horizontally in the direction of the slide rail 29, which facilitates the material to be shaken into the acupuncture groove 13 better.

[0031] The working principle of the present invention is:

[0032] When the unremoved dried fruits are poured into the elevator 2, the elevator 2 lifts the materials to a certain height and then drops them into the first vibrating screen 3. The first vibrating screen 3 vibrates and separates the product materials and the debris for the first time, and then the product materials fall into the screen plate 20 along the outlet of the first vibrating screen 3. The acupuncture plate 11 drives the crankshaft 27 to swing horizontally along the slide rail 29 through the motor 26. During the swinging process, the product materials roll into the acupuncture groove 13 along the silo door 23 by gravity. The staff can set each time by observing the time when the product materials basically fill the acupuncture groove 13. The interval time of the lateral swing is until the product materials fill the hole grooves 13. After the hole grooves 13 are filled, the product materials are sucked by the suction nozzle 19 of the suction cup mechanism 7 driven by the robot arm 6 and transferred to the carrier of the next process, thereby completing the screening and sorting of the materials this time; the excess materials and the debris that have not been removed fall into the second vibrating screen 5 through the outlet of the hole plate 11 under the action of gravity for re-screening, and the excess materials fall into the storage hopper 8 under the elevator through the second vibrating screen 5, and the cycle is repeated to perform multi-stage screening and sorting of the materials.

[0033] The present invention realizes three-level impurity removal by vibrating and pneumatic impurity removal twice before and after material sorting, improves the efficiency and qualified rate of dried fruit sorting, screens and sorts materials in an automatic cycle, and effectively reduces labor costs.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
