[0038] A feed port 25 is provided on the mixing box 2, and a feed pipe 26 is fixedly connected to the mixing box 2 at a position corresponding to the feed port 25. The outer wall of the feed pipe 26 at one end away from the mixing box 2 is provided with threads, and the feed pipe 26 is threadedly connected to a sealing cover 27.

[0039] When the raw materials need to be stirred, the staff unscrews the sealing cover 27 and injects the raw materials into the mixing box 2 through the feed port 25. The driving component 4 drives the stirring rod 22 to rotate, so that the first blade 221 and the second blade 222 stir the raw materials. The scraper 24 can clean the raw materials adhered to the inner wall of the mixing box 2 while stirring, thereby scraping off the raw materials on the inner wall of the mixing box 2, so that the raw materials in the mixing box 2 can be stirred more fully, thereby reducing the possibility of raw material waste.

[0040] Reference Figure 2 and Figure 3 In the present embodiment, in order to realize the replacement of the scraper 24, a first groove 231 is provided on the side of the connecting rod 23 away from the stirring rod 22, and a first protrusion 241 is fixedly connected to the side of the scraper 24 away from the mixing box 2, and the first protrusion 241 is threadedly connected to the connecting rod 23 through the first groove 231.

[0041] Reference Figure 2The driving assembly 4 includes a driving motor 41, which is fixedly connected to the mixing box 2. The output shaft of the driving motor 41 passes through the transmission box 3 and is rotatably connected to the transmission box 3. The output shaft of the driving motor 41 is fixedly connected with a bevel gear set 42.

[0043] In this embodiment, in order to better clean the inner wall of the mixing box 2, a lifting assembly 5 is further provided in the transmission box 3, and the lifting assembly 5 can drive the stirring rod 22 to move up and down.

[0044] The lifting assembly 5 includes a vertically placed hydraulic cylinder 51, the fixed end of the hydraulic cylinder 51 is fixedly connected to the inner wall of the transmission box 3, the piston rod of the hydraulic cylinder 51 is fixedly connected to the lifting plate 52, and a second groove 521 is provided on the side of the lifting plate 52 away from the hydraulic cylinder 51, and the lifting plate 52 is rotatably connected to the stirring rod 22 through the second groove 521.

[0045] When the inner wall of the mixing box 2 needs to be cleaned, the piston rod of the hydraulic cylinder 51 drives the lifting plate 52 to lift, and the lifting plate 52 drives the stirring rod 22 to lift. While lifting, the driving component 4 drives the stirring rod 22 to rotate, so that the scraper 24 cleans the inner wall of the mixing box 2 in all directions, thereby making the raw materials on the inner wall of the mixing box 2 more fully stirred, reducing the possibility of raw material waste.

[0046] A third groove 223 is provided at the bottom of the stirring rod 22, and a feeding hole 28 is provided at the bottom of the mixing box 2. A feeding pipe 6 is fixedly connected to the mixing box 2 at the position of the feeding hole 28. A discharge pipe 61 is fixedly connected to the bottom of the feeding pipe 6. The discharge pipe 61 is communicated with the feeding pipe 6. A discharge port 61 is provided at one end of the discharge pipe 6 away from the feeding pipe 6, and the discharge port 61 is connected to a straw forming machine (not shown in the figure); a feeding rod 62 is provided inside the feeding pipe 6, one end of the feeding rod 62 is rotatably connected to the bottom of the feeding pipe 6, and the other end of the feeding rod 62 passes through the feeding hole 28 and enters the mixing box 2. A spiral blade 622 is fixedly connected to the feeding rod 62, and the outer wall of the spiral blade 622 abuts against the inner wall of the feeding pipe 6. A second protrusion 621 is fixedly connected to the end of the feeding rod 62 entering the mixing box 2. When the second fan blade 222 abuts against the bottom of the mixing box 2, the second protrusion 621 is inserted into the stirring rod 22 through the third groove 223.

[0047] Reference Figure 2 , Figure 4 and Figure 5 The feed rod 62 is fixedly connected with a cover plate 63 at a position corresponding to the discharge hole 28. One end of the cover plate 63 away from the feed rod 62 abuts against the mixing box 2. A plurality of evenly distributed fan ring holes 631 are provided on the cover plate 63. A fan ring groove 632 is provided inside the cover plate 63. The fan ring groove 632 is connected with the fan ring hole 631. A spring 633 is provided in the fan ring groove 632. One end of the spring 633 is fixedly connected to the cover plate 63. The other end of the spring 633 is fixedly connected with a baffle plate 634. The baffle plate 634 can move in the fan ring groove 632.

[0048] After the stirring is completed, the second protrusion 621 is inserted into the third groove 223, the driving motor 41 drives the stirring rod 22 to rotate, the stirring rod 22 drives the feed rod 62 to rotate, and the feed rod 62 drives the cover plate 63 to rotate. At this time, the baffle plate 634 is affected by the centrifugal force and continuously moves into the fan ring groove 632, so that the interior of the mixing box 2 is connected with the interior of the feed pipe 6, and the raw materials enter the feed pipe 6 through the fan ring hole 631. At the same time, due to the rotation of the feed rod 62, the spiral blade 622 is driven to rotate, and the spiral blade 622 drives the raw materials to be output from the discharge pipe 61; when the raw materials are transported, the cover plate 63 stops rotating, and the baffle plate 634 is acted on by the elastic force of the spring 633 to move toward the fan ring hole 631, thereby blocking the fan ring hole 631, and the raw materials no longer enter the feed pipe 6.

[0049] The implementation principle of the feeding device for a straw forming machine provided in the present application is: when using the feeding device for the straw forming machine, the user rotates the sealing cover 27 to connect the mixing box 2 with the outside world, and injects the raw materials into the mixing box 2 through the feed port 25. After the raw materials are injected, the sealing cover 27 is covered to seal the mixing box 2.

[0050] When the raw materials need to be stirred, the driving motor 41 drives the stirring rod 22 to rotate through the bevel gear set 42. At the same time, the piston rod of the hydraulic cylinder 51 drives the stirring rod 22 to rise and fall through the lifting plate 52, so that the scraper 24 cleans the inner wall of the mixing box 2, thereby making the raw materials on the inner wall of the mixing box 2 more fully stirred and reducing the possibility of raw material waste.

[0051] When it is necessary to transport raw materials to the straw forming machine, the second protrusion 621 is inserted into the stirring rod 22 through the third groove 223, and the driving motor 41 drives the stirring rod 22 to rotate, and the stirring rod 22 drives the feeding rod 62 to rotate, and the feeding rod 62 drives the cover plate 63 to rotate. At this time, the baffle plate 634 is affected by the centrifugal force and continuously moves into the fan ring groove 632, so that the interior of the mixing box 2 is connected with the interior of the feeding pipe 6, and the raw materials enter the feeding pipe 6 through the fan ring hole 631. At the same time, due to the rotation of the feeding rod 62, the spiral blade 622 is driven to rotate, and the spiral blade 622 drives the raw materials to be output from the discharge pipe 61.

[0052] When the raw material is conveyed, the cover plate 63 stops rotating, and the shielding plate 634 moves toward the fan ring hole 631 under the elastic force of the spring 633 , thereby shielding the fan ring hole 631 , and the raw material no longer enters the conveying pipe 6 .

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
