Technical Field
[0001] The present application relates to the technical field of mixing, and in particular to a cement mixer. Background Art
[0002] As an important equipment in the building materials industry, cement mixers are widely used in the preparation of concrete. Most of the cement mixers on the market are designed to improve mixing efficiency, but not enough attention is paid to the cleaning of the inner wall of the mixer. During the mixing process, cement slurry is easy to adhere to the inner wall. Long-term accumulation not only affects the mixing efficiency, but may also cause uneven mixing and affect the quality of concrete. Existing cleaning methods mostly rely on manual cleaning, which is not only labor-intensive, but also difficult to ensure the cleaning effect; therefore, we propose a cement mixer to solve this problem.
[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

The existing cleaning methods mostly rely on manual cleaning, which is not only labor-intensive, but also has the problem that the cement slurry is easy to adhere to the inner wall during the mixing process. The application provides a cement mixer.
[0005] The present application provides a cement mixer adopting the following technical solution:
[0006] A cement mixer comprises a support frame, a tank body is fixedly connected to the top of the support frame, a feed pipe is arranged on the top of the tank body, a dredging mechanism is arranged on the feed pipe, a cleaning mechanism is arranged on the tank body, and a stirring assembly is arranged on the tank body;
[0007] The cleaning mechanism comprises a third motor, the top of the third motor is connected to a cleaning plate via a first coupling, the third motor is fixedly connected to the bottom of the support frame, and the cleaning plate is fitted to the inner wall of the tank body.
[0008] Preferably, the stirring assembly comprises a first motor, the first motor is connected to a rotating shaft via a second coupling, and a plurality of stirring blades are fixedly connected to the outer side of the rotating shaft.
[0009] Preferably, a limit plate is fixedly connected to the top of the tank body, the limit plate is fixedly connected to the outer side of the first motor, and one end of the rotating shaft away from the first motor is rotatably connected to the inner side of the tank body.
[0010] Preferably, the dredging mechanism includes a second motor, the second motor is fixedly connected to the top of the tank body, and one end of the output shaft of the second motor is transmission-connected to the first gear via a third coupling.
[0011] Preferably, a second gear is meshed on one side of the first gear, and a first rotating rod is fixedly connected to the inner side of the first gear.

[0020] The following is combined with Figure 1-3 This application is described in further detail.
[0021] The present application embodiment discloses a cement mixer. Figure 1 and Figure 3 A cement mixer comprises a support frame 1, a tank body 2 is fixedly connected to the top of the support frame 1, a feed pipe 3 is arranged on the top of the tank body 2, a dredging mechanism is arranged on the feed pipe 3, a cleaning mechanism is arranged on the tank body 2, and a stirring assembly is arranged on the tank body 2;
[0022] The cleaning mechanism includes a third motor 11, the top of the third motor 11 is connected to a cleaning plate 12 through a first coupling transmission, the third motor 11 is fixedly connected to the bottom of the support frame 1, and the cleaning plate 12 is in contact with the inner wall of the tank body 2; the cleaning plate 12 is connected to the first coupling transmission for rotation, and when the cleaning plate 12 rotates, the cleaning plate 12 rotates along the inner wall of the tank body 2, thereby scraping off the cement attached to the inner side of the tank body 2. Since the cleaning plate 12 is in contact with the inner wall of the tank body 2, it can fully cover the inner wall of the mixer for cleaning, effectively avoiding the residue of cement slurry.
[0023] Reference Figure 3 The stirring assembly includes a first motor 5 , which is connected to a rotating shaft 14 through a second coupling, and a plurality of stirring blades 13 are fixedly connected to the outer side of the rotating shaft 14 .
[0024] Reference Figure 3 The top of the tank body 2 is fixedly connected with a limit plate 4 , the limit plate 4 is fixedly connected to the outer side of the first motor 5 , and one end of the rotating shaft 14 away from the first motor 5 is rotatably connected to the inner side of the tank body 2 .
[0025] Reference Figure 2 The dredging mechanism includes a second motor 6, which is fixedly connected to the top of the tank body 2, and one end of the output shaft of the second motor 6 is connected to the first gear 7 through a third coupling.
[0026] Reference Figure 2 A second gear 8 is meshed with one side of the first gear 7 , and a first rotating rod 9 is fixedly connected to the inner side of the first gear 7 .
[0027] Reference Figure 2 , a second rotating rod 10 is fixedly connected to the inner side of the second gear 8, and the second gear 8 and the first gear 7 are both rotatably connected to the inner side of the discharge pipe 3; the first gear 7 is driven to rotate by the third coupling, and when the first gear 7 rotates, the first gear 7 drives the second gear 8 meshing on the outer side to rotate, and because the inner sides of the first gear 7 and the second gear 8 are respectively fixedly connected with the first rotating rod 9 and the second rotating rod 10, the rotation of the second motor 6 drives the first rotating rod 9 and the second rotating rod 10 to rotate, thereby transferring the cement raw material into the inner side of the tank body 2, which can prevent the material inside the discharge pipe 3 from being blocked.
[0028] The implementation principle of a cement mixer in the embodiment of the present application is as follows: when the staff has finished using the device, first inject water into the inner side of the tank body 2, and then turn on the third motor 11. When the third motor 11 rotates, the third motor 11 is connected to the cleaning plate 12 through the first coupling transmission to rotate. When the cleaning plate 12 rotates, the cleaning plate 12 rotates along the inner wall of the tank body 2, so as to scrape off the cement attached to the inner side of the tank body 2. Since the cleaning plate 12 fits the inner wall of the tank body 2, it can fully cover the inner wall of the mixer for cleaning, effectively avoiding the residue of cement slurry, reducing the dependence on manual cleaning, and reducing labor intensity.
[0029] When adding cement raw materials to the inner side of the tank body 2, the staff turns on the second motor 6. When the second motor 6 rotates, the second motor 6 drives the first gear 7 to rotate through the third coupling. When the first gear 7 rotates, the first gear 7 drives the second gear 8 meshing on the outer side to rotate. Because the inner sides of the first gear 7 and the second gear 8 are respectively fixedly connected with the first rotating rod 9 and the second rotating rod 10, the rotation of the second motor 6 drives the first rotating rod 9 and the second rotating rod 10 to rotate, thereby transferring the cement raw materials into the inner side of the tank body 2, which can prevent the material inside the discharge pipe 3 from being blocked, achieve an anti-blocking effect, and greatly reduce the manufacturing cost.
