[0032] A construction raw material mixing device, which includes:

[0033] Substrate 1, with symmetrically distributed support legs 2 fixedly installed on both sides of the bottom of substrate 1. A support rod 7 is rotatably installed on the top of substrate 1, and the bottom end of support rod 7 penetrates through the top of substrate 1 and extends below the bottom of substrate 1.

[0034] The support rod 7 is fixedly installed with an electric telescopic rod 11 through a vertical groove opened at its top. The driving end of the electric telescopic rod 11 is fixedly installed with a fixing frame 12. On both sides of the bottom of the fixing frame 12, there are fixedly installed cover plates 15.

[0038] In one preferred embodiment, the cleaning mechanism includes a cleaning pipe 22, and the cleaning pipe 22 is fixedly installed at the bottom of the other cover plate 15.

[0039] In one embodiment, the driving mechanism includes a second motor 16, and the second motor 16 is fixedly installed on the top of the substrate 1. The driving end of the second motor 16 penetrates through the top of the substrate 1 and extends below the bottom of the substrate 1 and is located on one side of the support rod 7. A second gear 21 is fixedly installed on the driving end of the second motor 16.

[0042] In one preferred embodiment, a sealing gasket is adhesively bonded to the side of the bottom of the cover plate 15, ensuring the sealing performance of the stirring barrel 3 and the cleaning barrel 4 during use.

[0043] The working principle of the present utility model is as follows: The entire device is controlled by a master control button. Since the devices matched with the control button are common devices and belong to existing common knowledge technologies, the electrical connection relationship and the specific circuit structure are not elaborated herein. During use, the construction raw materials are added into the interior of the mixing barrel 3 through the feed pipe 8, and then the first motor 9 is controlled to start working. The driving end of the first motor 9 drives the mixing shaft 18 to rotate. The rotation of the mixing shaft 18 drives the mixing roller 19 to rotate. The rotation of the mixing roller 19 can quickly stir and mix the raw materials inside the mixing barrel 3. The mixed raw materials are discharged through the discharge pipe 6 for use. Later, when it is necessary to clean the interior of the device, first connect the external pipe 14 to an external water supply hose. The cleaning water enters the interior of the cleaning pipe 22 through the external pipe 14, and then the cleaning water is sprayed out through the spray head 23 into the interior of the cleaning barrel 4. A certain amount of cleaning water is pre-stored in the interior of the cleaning barrel 4. Subsequently, the electric telescopic rod 11 is controlled to start working. The driving end of the electric telescopic rod 11 drives the fixed frame 12 to move vertically, causing the fixed frame 12 to move upward and drive the two cover plates 15 to move. The movement of the two cover plates 15 drives the mixing mechanism and the cleaning mechanism to move respectively. The mixing mechanism is moved out of the interior of the mixing barrel 3 to above the top of the mixing barrel 3, and the cleaning mechanism is moved out of the interior of the cleaning barrel 4 to above the top of the cleaning barrel 4. Then, the second motor 16 is controlled to start working. The driving end of the second motor 16 drives the second gear 21 to rotate. Through the meshing of the second gear 21 with the first gear 20, the first gear 20 drives the support rod 7 to rotate. The rotation of the support rod 7 drives the fixed frame 12 to rotate through the electric telescopic rod 11. The fixed frame 12 drives the two cover plates 15 to rotate, causing the mixing mechanism and the cleaning mechanism to exchange positions with each other. Then, the mixing mechanism is controlled to enter the interior of the cleaning barrel 4, and the cleaning mechanism enters the interior of the mixing barrel 3. After the cleaning structure enters the interior of the mixing barrel 3, through the pressurization of the booster pump 13, the cleaning water is sprayed out at a high speed into the interior of the mixing barrel 3 to clean the interior of the mixing barrel 3. After the mixing mechanism enters the interior of the cleaning barrel 4, it comes into contact with the cleaning water pre-stored in the interior of the cleaning barrel 4 and completes self-cleaning through the self-rotation of the mixing mechanism. The sewage located inside the mixing barrel 3 can be directly discharged through the discharge pipe 6, and the sewage inside the cleaning barrel 4 can be discharged through the sewage pipe 17. After the cleaning is completed, the above steps are operated in reverse, and the cleaning mechanism and the mixing mechanism are controlled to return to their original positions. Through the position exchange of the mixing mechanism and the cleaning structure, the device can realize the self-cleaning function of the mixing barrel 3 and the mixing mechanism. Moreover, between the mixing mechanism and the mixing barrel 3, they are two independent components and can be separated by mechanical drive, making the cleaning and maintenance of the mixing barrel 3 and the mixing mechanism very simple, without the need for cumbersome disassembly and assembly operations, greatly improving the user experience and having high practicality.

[0044] During the process of controlling the vertical movement of the stirring mechanism and the cleaning mechanism, the movement of the fixing frame 12 will slide on the outer wall of the limiting rod 10 through the fixing hole 26. By limiting the fixing frame 12 with the limiting rod 10, the stirring mechanism and the cleaning mechanism are more stable during the vertical movement. At the same time, during the sliding of the fixing frame 12 on the outer wall of the limiting rod 10, it will drive the ball 24 to roll into contact with the limiting rod 10, greatly reducing the friction between the fixing frame 12 and the limiting rod 10, improving the working efficiency of the electric telescopic rod 11, and also extending the service life of the fixing frame 12.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
