[0014] Such as Figure 1-2As shown in the figure, an anti-rust spraying device for the surface of nuts includes a spraying chamber 1 and a hanging rack. A conveying track is provided in the spraying chamber 1, and inlets and outlets are respectively provided at both ends of the spraying chamber 1. The conveying track includes two rows of conveying rollers 2, and a channel 3 is formed between the two rows of conveying rollers 2. The conveying rollers 2 are driven to rotate by a power mechanism. A number of nozzles 4 are installed in the spraying chamber 1. The hanging rack includes a vertical pipe 5 and a central rod 6. The upper end of the vertical pipe 5 passes through the channel 3 and is successively connected with a tray 7 and a rotating gear 8. The tray 7 is rotatably connected to the vertical pipe 5, and the rotating gear 8 is fixedly connected to the vertical pipe 5. The central rod 6 is located inside the vertical pipe 5. The upper end of the central rod 6 extends out of the vertical pipe 5 and is rotatably connected with a lifting plate 9. Both sides of the lifting plate 9 are respectively rotatably connected with rollers 10. Fixed mounting plates 11 are respectively provided above the conveying rollers 2, and undulating wave plates 12 with gradually changing heights are installed on the fixed mounting plates 11. The rollers 10 are respectively placed on the wave plates 12. A rack 13 is fixedly connected to the inner side of one of the fixed mounting plates 11, and the rotating gear 8 meshes with the rack 13. A number of hanging rods 14 are successively provided on the vertical pipe 5 from bottom to top. Each layer of the hanging rods 14 includes a number of hanging rods 14 arranged in a circumferential array around the vertical pipe 5. One end of the hanging rod 14 is hinged to the vertical pipe 5, and the other end is detachably connected with a lifting rope 15. A number of lifting rope holes 16 communicating with the inside of the vertical pipe 5 are provided on the vertical pipe 5. The lifting rope holes 16 correspond to the lifting ropes 15 one by one. After passing through the corresponding lifting rope holes 16, the lifting ropes 15 are fixedly connected to the central rod 6. The nuts are successively sleeved on the hanging rods 14, and after sleeving, the lifting ropes 15 are connected to the hanging rods 14. The hanging racks are successively placed into the spraying chamber 1. The conveying rollers 2 support the tray 7, the rotating gear 8 meshes with the rack 13, and the rollers 10 are respectively located on the wave plates 12. The conveying rollers 2 rotate, causing the hanging racks to move forward successively. During the forward movement, the rollers 10 move up and down with the height change of the wave plates 12, driving the central rod 6 to move up and down, and then driving the hanging rods 14 to swing up and down through the lifting ropes 15, so that the nuts on the hanging rods 14 can slide back and forth on the hanging rods 14. At the same time, the rack 13 rotates, driving the hanging rack to rotate. The nozzles 4 in the spraying chamber 1 are connected to spraying equipment, and the coating is sprayed on the surface of the nuts. Since the nuts are constantly rotating and sliding on the hanging rods 14, the nuts at various positions and various parts of the nuts can be evenly sprayed. And since the nuts are sleeved on the hanging rods 14 and adjacent nuts can be closely adjacent due to gravity, the inside of the nuts is prevented from being directly sprayed.

[0015] Further, a key 17 is fixedly connected to the central rod 6, and a vertically arranged key groove 18 is provided on the inner wall of the vertical pipe 5. The key 17 is located in the key groove 18. The cooperation of the key 17 and the key groove 18 enables the central rod 6 and the vertical pipe 5 to rotate synchronously, and the central rod 6 can move up and down relative to the vertical pipe 5 inside the vertical pipe 5.

[0016] Further, a baffle 19 is fixedly connected to one end of the hanging rod 14 close to the vertical pipe 5. The baffle 19 restricts the position of the nut on the hanging rod 14 to prevent the nut from being too close to the vertical pipe 5.

[0017] Further, a threaded hole 20 is provided at one end of the hanging rod 14 away from the vertical pipe 5. A bolt is threadedly connected in the threaded hole 20, and one end of the lifting rope 15 is fixedly connected to the bolt. After the hanging rod 14 is filled with nuts, the bolt is screwed into the threaded hole 20, and the hanging rod 14 is fixed by the lifting rope 15. When discharging, the bolt is screwed out, and the hanging rod 14 is tilted downward to achieve rapid discharging.

[0018] Further, a polytetrafluoroethylene gasket is installed in the lifting rope hole 16, and the lifting rope 15 is a nylon rope. The polytetrafluoroethylene gasket has good wear resistance and self-lubricating properties, reducing the friction with the lifting rope 15.

[0019] It is worth mentioning that the technical features such as the spraying equipment and the driving device involved in the patent application of the present utility model should be regarded as the prior art. The specific structures, working principles, possible control methods, and spatial layout methods of these technical features can be selected conventionally in the art, and should not be regarded as the inventive points of the patent of the present utility model. The patent of the present utility model will not be further specifically elaborated.

[0020] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
