[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a multi-stage sorting device for agricultural products includes a sorting housing 1. A feeding hopper 2 is installed on the upper end of one side of the sorting housing 1. A feeding plate 17 is provided on the lower side of the other side of the sorting housing 1 by screws. The feeding plate 17 is located below one end of the outer side of the sorting plate 34. A vibrating screen sorting device 3 is installed on the front and rear sides of the sorting housing 1. Through slots 11 are arranged on the upper sides of both the front and rear sides of the sorting housing 1.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, the vibrating screen sorting device 3 includes an elastic component 31, which includes a spring and a rubber damper. The elastic components 31 are all located inside the through groove 11. Each elastic component 31 has a connecting plate 32 at its upper end, which passes through the through groove 11. A vibrating seat 35 is provided at one end of the outer side of each connecting plate 32, and a slot plate 33 is provided at one end of the inner side of each connecting plate 32. A sorting plate 34 is snapped into the slot plate 33. The slot plate 33 and the sorting plate 34 are designed to be inclined. The diameter of the gradient hole groove 341 increases from left to right. The sorting plate 34 has a gradient hole groove 341, and the slot plate 33 is connected to the sorting plate 34 by screws. Fixed plates 36 are arranged on the front and rear outer surfaces of the sorting machine housing 1. A rotating rod 37 is rotatably connected between the fixed plates 36. Each rotating rod 37 is equipped with a motor 39 at one end, which is driven by an external control module. An eccentric block 38 is installed on the outer wall of the rotating rod 37 and below the vibrating seat 35. Through the inclined sorting plate 34 and the gradient hole groove 341, the agricultural products roll and fall onto the corresponding inclined discharge plate 14. Multiple inclined discharge plates 14 are provided to achieve multi-level sorting of agricultural products. The driving of the elastic component 31, connecting plate 32, rotating rod 37 and eccentric block 38 causes the sorting plate 34 to vibrate during the sorting process, which speeds up the sorting effect and prevents agricultural products from getting stuck. The slot plate 33 is engaged with the sorting plate 34 and connected by screws. It can be disassembled and replaced according to the shape of the sorted agricultural products, which improves the practicality of the device.

[0031] like Figure 2 and Figure 3As shown, inclined discharge plates 14 are fixedly connected between the partitions 12. The bottom of the inclined discharge plates 14 is designed to be inclined. The outlet end of each inclined discharge plate 14 is provided with a silicone soft curtain 18. The inclined discharge plates 14 are all located above the collection box 15. The bottom of the inclined discharge plates 14 has a mesh structure. The partitions 12 are arranged inside the sorting machine housing 1. Limiting grooves 13 are opened on the inner side of the sorting machine housing 1 and on both sides of the partitions 12. Limiting plates 16 are snapped into the limiting grooves 13. The collection box 15 is fixedly connected between the two limiting plates 16. By setting the inclined discharge plates 14 at the bottom and the silicone soft curtain 18 at the discharge end, the agricultural products can be guided to slide into the collection box, reducing the damage caused by rolling impact. In addition, the bottom of the inclined discharge plates 14 has a mesh structure and the collection box 15 is set on the bottom side, which can collect the leaked impurities. The collection box 15 is provided with limiting plates 16 at both ends, which can be removed for cleaning by pulling it out.

[0032] This utility model provides a multi-stage sorting device for agricultural products. The specific working principle is as follows: Agricultural products (such as red dates, garlic, etc.) are poured into the feed hopper 2, so that the agricultural products fall onto the sorting plate 34. At the same time, the motor 39 is started to drive the rotating rod 37 to rotate, so that the eccentric block 38 rotates and hits the vibrating seat 35. Under the elastic action of the elastic component 31, the sorting plate 34 vibrates, which speeds up the sorting effect and prevents agricultural products from getting stuck. The agricultural products roll and fall onto the corresponding inclined discharge plate 14. The inclined plate 14 makes the agricultural products roll out. A silicone soft curtain 18 is set to guide the agricultural products into the collection box. The bottom of the inclined discharge plate 14 has a mesh structure and a collection box 15 is set on the bottom side to collect the fallen impurities. The collection box 15 is equipped with limit plates 16 at both ends, which can be removed for cleaning by pulling it out. The slot plate 33 is snapped into the sorting plate 34 and connected by screws, which can be disassembled and replaced according to the shape of the sorted agricultural products.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
