DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-4 This application is described in further detail.
[0033] The embodiment of the present application discloses a mixer.

[0035] Reference Figure 2The stirring mechanism 2 includes a motor 21 and a fixing rod 22 for fixing the motor 21. The fixing rod 22 is horizontally fixed on the upper side of the stirring tank 1. A stirring shaft 23 is fixed at the output end of the motor 21. The stirring shaft 23 vertically extends into the stirring tank 1. The axis of the stirring shaft 23 and the axis of the stirring tank 1 are located in the same straight line. A plurality of horizontally arranged stirring rods 24 are fixed at intervals in the length direction of the stirring shaft 23. A stirring blade 25 is fixed at one end of the stirring rod 24 away from the stirring shaft 23. When the motor 21 drives the stirring shaft 23 to rotate, the stirring rod 24 and the stirring blade 25 stir the material in the stirring tank 1, so as to achieve uniform stirring of the material in the stirring tank 1.
[0036] Reference Figure 3 and Figure 4 The scraper mechanism 3 includes a scraper 31 and a scraper assembly 32. There are multiple scrapers 31. In this embodiment, there are two scrapers 31. The two scrapers 31 are respectively arranged at two parallel inner walls of the discharge pipe 12. The length direction of the scraper 31 is parallel to the discharge direction of the discharge pipe 12.
[0037] The scraper assembly 32 includes two sliding rods 321 of the same number as the scraper 31. The side of the scraper 31 away from the inner wall of the discharge pipe 12 is fixedly connected to the sliding rod 321. The length direction of the sliding rod 321 is perpendicular to the scraper 31. The scraper 31 is fixed to one end of the sliding rod 321. A through hole 121 is opened on the side wall of the discharge pipe 12. The other end of the sliding rod 321 extends horizontally out of the discharge pipe 12 through the through hole 121. A connecting rod 322 is fixed between the two sliding rods 321. The connecting rod 322 is located on the outside of the discharge pipe 12. A moving rod 323 is fixed to the middle section of the connecting rod 322. The moving rod 323 moves away from the sliding rod 32 1, the moving rod 323 is extended horizontally, and a fixing plate 324 is vertically fixed on one end of the moving rod 323 away from the connecting rod 322.

When the output end of the cylinder 325 is extended or retracted, the moving rod 323 can be reciprocated in the horizontal direction. Under the connection of the connecting rod 322, the sliding rod 321 can be horizontally slid, thereby realizing the horizontal reciprocating scraping of the inner wall of the discharge pipe 12 by the scraper 31, thereby reducing the blockage caused by the adhesion of materials to the discharge pipe 12.
[0038] Reference Figure 2 and Figure 3The discharge mechanism 4 includes a switch plate 41 and a rotating shaft 42. The size of the switch plate 41 is the same as the inner cross-section of the discharge pipe 12. When the switch plate 41 is parallel to the discharge direction of the discharge pipe 12, the discharge pipe 12 is in a discharge state. When the switch plate 41 is perpendicular to the discharge direction of the discharge pipe 12, the discharge pipe 12 is in a closed state. The rotating shaft 42 is fixedly installed at the center of the switch plate 41, and the rotating shaft 42 is parallel to the length direction of the switch plate 41. The rotating shaft 42 is horizontally rotatably installed in the discharge pipe 12, and one end of the rotating shaft 42 horizontally extends out of the discharge pipe 12. A disc 43 is vertically fixed to the end of the rotating shaft 42 extending out of the discharge pipe 12, and the center of the disc 43 and the axis of the rotating shaft 42 are located in the same straight line.
[0039] The discharge mechanism 4 also includes a fixing component 44 for fixing the rotation state of the switch plate 41. The fixing component 44 includes a plurality of sockets 441 that are opened through the disc 43. The plurality of sockets 441 are evenly spaced in an array about the center of the disc 43, and the axes of the sockets 441 are parallel to the center of the disc 43. A socket 442 is also opened on the outer wall of the discharge pipe 12. The fixing component 44 also includes an insertion rod 443. When the socket 442 is aligned with one of the sockets 441, the insertion rod 443 can pass through the socket 442 and the socket 441 at the same time to fix the position of the disc 43. A connecting rope 444 is fixed to the end of the insertion rod 443 away from the socket 442, and the end of the connecting rope 444 away from the insertion rod 443 is fixed to the outer wall of the discharge pipe 12. When the rod 443 is inserted into the socket 441 and the rod 443 at the same time, the position of the disc 43 can be fixed, thereby adjusting the rotation angle of the switch plate 41 and adjusting the discharge amount. When the rod 443 is away from the socket 441 and the rod 443, the rod 443 is not easy to be lost when connected with the connecting rope 444.
[0040] The discharge mechanism 4 also includes a baffle 45 rotatably installed at the discharge pipe 12. The baffle 45 is horizontally arranged on the side of the discharge pipe 12 away from the mixing tank 1. The baffle 45 is an arc-shaped plate, and the two parallel sides of the baffle 45 are tilted toward the side close to the rotating shaft 42 and abut against the side wall of the discharge pipe 12. The baffle 45 can block the side of the discharge pipe 12 away from the mixing tank 1. A mounting rod 46 is fixed on the baffle 45, and the other end of the mounting rod 46 is fixedly connected to the part of the rotating shaft 42 extending out of the discharge pipe 12, so that the baffle 45 can rotate around the rotating shaft 42 as the axis.
[0041] The implementation principle of a mixer in the embodiment of the present application is:
[0042] When the material is put into the mixing tank 1 for mixing, the mixing mechanism 2 mixes the material in the mixing tank 1 evenly. When the mixing is completed and the material is discharged, the switch plate 41 and the baffle 45 are opened at the same time by rotating the disc 43 to discharge the material. The position of the disc 43 can be fixed by inserting the insertion rod 443 into the socket 441 and the socket 442 at the same time. During the discharging process, the cylinder 325 drives the sliding rod 321 to slide horizontally, so that the scraper 31 scrapes the inner wall of the discharge pipe 12, thereby improving the discharging effect and reducing the blockage of the discharge port caused by the accumulation of residual materials.
[0043] 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.
