Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] This utility model proposes a double-helix mixing device, comprising: The shell 1 has a discharge port formed inside the lower wall; The feed hopper 6 is located above the housing 1, and its discharge end penetrates the upper wall of the housing 1; The discharge end of the feed hopper 6 is fixedly inserted through the upper wall of the shell 1, which makes it convenient for workers to add the materials to be mixed into the shell 1, and at the same time, the discharge port can conveniently discharge the mixed materials out of the shell 1. There is a pair of rotating shafts 2, both of which are rotatably mounted on the upper inner surface of the housing 1. The spiral stirring blade 24 is fixedly installed on the outer surface of the rotating shaft 2; The rotation of the shaft 2 can drive the spiral stirring blades 24 to rotate simultaneously, which can mix the materials inside the shell 1; The first gear 3, there is a pair, both located on the top of the housing 1, and are fixedly connected to the top of a pair of rotating shafts 2 respectively; The second gear 4 is rotatably mounted on the upper end face of the housing 1 and is meshed with a pair of first gears 3 respectively; The rotation of one first gear 3 can drive the rotation of the second gear 4, which in turn drives the other first gear 3 to rotate simultaneously. The first frame 5 is fixedly installed on the lower end face of the housing 1; The second frame 7 is slidably installed inside the first frame 5; Third-party box 8 is set on the bottom face of second box 7; Screen 9 is fixedly installed inside the third-party frame 8; The screen 9 can screen the material discharged from the outlet, while the third frame 8 is fixedly installed on the lower end face of the second frame 7 by bolts, which can facilitate the replacement of screens 9 with different mesh sizes; A driving component is located on the first block 5 and is used to drive the second block 7 to slide.

[0017] Specifically, the driving components include; There are two pairs of sliding rods 10, both of which slide through the side wall of the first frame 5, and the ends of the two pairs of sliding rods 10 that are close to each other are fixedly connected to the outer wall of the second frame 7. Under the action of the two pairs of sliding rods 10, the second box 7 can be limited, so that the second box 7 can slide back and forth stably within the first box 5. There is a pair of connecting plates 11, which are respectively located on both sides of the first frame 5, and one end of the connecting plate 11 is fixedly connected to the end of the pair of sliding rods 10 away from the second frame 7. The tension spring 12 is fixedly connected at one end to the outer wall of the first frame 5 and at the other end to one end face of a connecting plate 11. Under the action of the tension spring 12, a force can be applied to one connecting plate 11, causing it to move closer to the first frame 5, and causing the other connecting plate 11 to move away from the first frame 5. The support plate is fixedly installed on the lower end face of the housing 1; The first motor 13 is fixedly installed on the lower end face of the support plate; Cam 14 is fixedly mounted on the output end of the first motor 13, and its outer surface is in contact with one side wall of a connecting plate 11; The rotation of the output end of the first motor 13 can drive the cam 14 to rotate simultaneously. The outer surface of the cam 14 rotates and contacts one end face of a connecting plate 11, which can drive one connecting plate 11 to move closer to the first square frame 5, and cause the other connecting plate 11 to slide away from the first square frame 5. At this time, under the action of the two pairs of sliding rods 10, the second square frame 7, the third square frame 8 and the screen 9 can slide back and forth, so that the screen 9 can screen the material. At the same time, a baffle plate is slidably installed through one side wall of the first square frame 5. The upper end face of the baffle plate contacts one end of the discharge port, which can seal the discharge port and prevent the material in the shell 1 from flowing out of the discharge port.

[0018] Specifically, an annular groove 15 is formed on the inner wall surface of the housing 1, an annular block 16 is slidably installed in the annular groove 15, and a scraper 17 is fixedly installed on the lower end face of the annular block 16, with one end face of the scraper 17 in contact with the inner wall surface of the housing 1. The sliding of the annular block 16 within the annular groove 15 can drive the scraper 17 to rotate, allowing the scraper 17 to scrape off the material adhering to the inner wall of the housing 1, thereby improving the mixing quality. A connecting rod 18 is rotatably mounted on the upper inner surface of the housing 1. A third gear 19 is fixedly mounted on the bottom end of the connecting rod 18. An internal gear ring 20 that meshes with the third gear 19 is fixedly mounted on the inner surface of the annular block 16. The rotation of the connecting rod 18 can drive the third gear 19 to rotate simultaneously. At this time, the rotation of the third gear 19 can drive the internal gear ring 20, causing the annular block 16 to slide in the annular groove 15.

[0019] Specifically, a support frame 21 is fixedly installed on the upper end face of the housing 1, and a second motor 22 is fixedly installed on the upper end face of the support frame 21. The output end of the second motor 22 is fixedly connected to the top end of the connecting rod 18. The rotation of the output end of the second motor 22 can drive the connecting rod 18 to rotate simultaneously. A fourth gear 23 is fixedly mounted on the outer surface of the output end of the second motor 22. The fourth gear 23 meshes with a first gear 3. The rotation of the output end of the second motor 22 can drive the fourth gear 23 to rotate simultaneously. The rotation of the fourth gear 23 can drive the first gear 3 to rotate, and the rotation of the first gear 3 can drive the second gear 4 to rotate. At this time, the rotation of the second gear 4 can drive the other first gear 3 to rotate simultaneously.

[0020] Specifically, a sealing plate 25 is hinged to the discharge end of the feed hopper 6, and a spring plate 26 is fixedly installed on the lower end face of the sealing plate 25. The end of the spring plate 26 away from the sealing plate 25 is fixedly connected to the outer wall surface of the feed hopper 6. The spring plate 26 can apply a force to the sealing plate 25, causing the sealing plate 25 to seal the discharge end of the feed hopper 6. At the same time, when material is added to the feed hopper 6, the weight of the material itself can apply a downward pressure to the sealing plate 25, causing the sealing plate 26 to flip, so that the material in the feed hopper 6 can fall into the housing 1 through the discharge end. After the material has fallen, the spring plate 26 can apply a force to the sealing plate 25, causing it to flip and seal the discharge end of the feed hopper 6. This can prevent the dust generated by the material in the housing 1 from being discharged to the outside through the feed hopper 6 when the material has completely fallen into the housing 1, thus preventing pollution to the external environment.

[0021] Working principle: In actual use, the operator first starts the second motor 22. The rotation of the output end of the second motor 22 drives the fourth gear 23 and the connecting rod 18 to rotate simultaneously. The rotation of the fourth gear 23 drives one of the first gears 3 to rotate, and the rotation of the first gear 3 drives the second gear 4 to rotate. At this time, the rotation of the second gear 4 drives the other first gear 3 to rotate simultaneously. The rotation of the pair of first gears 3 drives the pair of rotating shafts 2 and the pair of spiral stirring blades 24 to rotate simultaneously. The rotation of the connecting rod 18 drives the third gear 19 to rotate simultaneously. At this time, the rotation of the third gear 19 can... The internal gear ring 20 is driven, causing the annular block 16 to slide within the annular groove 15. This sliding motion of the annular block 16 within the annular groove 15 drives the scraper 17 to rotate, allowing the scraper 17 to scrape the inner wall of the housing 1. At this time, the worker adds material into the feed hopper 6. Simultaneously, the weight of the material in the feed hopper 6 exerts a downward pressure on the sealing plate 25, causing the sealing plate 26 to flip, facilitating the material in the feed hopper 6 to fall into the housing 1 through the outlet. After the material has fallen, the spring plate 26 applies a force to the sealing plate 25, causing it to flip and rotate the feed hopper. The discharge end of hopper 6 is sealed to prevent the material from falling completely into the shell 1. This prevents the dust generated by the material inside the shell 1 from being discharged into the outside environment and causing pollution. At this time, a pair of rotating shafts 2 drive a pair of spiral stirring blades 24 to rotate, stirring the material inside the shell 1 and mixing it. The scraper 17 can scrape off the material adhering to the inner wall of the shell 1, improving the mixing quality. After mixing is complete, the operator starts the first motor 13 and simultaneously pulls the baffle plate. The output end of the first motor rotates, driving the cam 14 to rotate simultaneously. The cam 14 rotates, and its outer surface connects with a connecting plate 11. With one end face in contact, a connecting plate 11 can be moved closer to the first frame 5, causing the other connecting plate 11 to slide away from the first frame 5. At the same time, under the action of the tension spring 12 and the two pairs of sliding rods 10, the second frame 7, the third frame 8, and the screen 9 can slide back and forth. At this time, the material falls from the discharge port into the second frame 7, and the reciprocatingly sliding screen 9 screens the material. At the same time, the third frame 9 can be removed from the second frame 7 by the action of the bolts, which makes it convenient for the staff to change the screen 9 of different mesh sizes according to the type of mixed material, bringing convenience to people.
