[0026] A mortar mixing device with a quantitative feeding structure comprises a mixing tank 1 and a weighing box 17, the top of the mixing tank 1 is connected to a premixing tank 3, and a mixing mechanism is arranged in the mixing tank 1 and the premixing tank 3, a plurality of feeding pipes 15 are connected to the premixing tank 3, and a positioning ring 16 is fixedly connected to the plurality of feeding pipes 15, a plurality of positioning rods 18 are fixedly connected to the bottom of the weighing box 17, and the plurality of positioning rods 18 are movably inserted in the positioning ring 16, a plurality of supporting plates 14 corresponding to the feeding pipes 15 are fixedly connected to the surface of the premixing tank 3, a plurality of pressure sensors 19 are fixedly installed on the top of the supporting plates 14, and the lower ends of the positioning rods 18 are pressed tightly on the pressure sensors 19;

[0027] In this embodiment, the positioning rod 18 is inserted into the positioning ring 16, so that the premixing tank 3 can be positioned to prevent the premixing tank 3 from being displaced. The positioning rod 18 is pressed against the pressure sensor 19, so that the pressure sensor 19 can detect the weight of the material in the premixing tank 3.

[0028] The bottom of the premixing tank 3 is connected with a plug-in pipe 21, which is plugged into the feed pipe 15, and a solenoid valve 22 is provided on the plug-in pipe 21;

[0029] The bottom of the premixing tank 3 is connected with a feed pipe 7, and the feed pipe 7 is connected with the top of the stirring and mixing tank 1;

[0030] The stirring mechanism includes a driving motor 4, a rotating rod 5, a first stirring rod 6 and a second stirring rod 9. The driving motor 4 is fixedly installed at the bottom of the premixing tank 3. The output shaft of the driving motor 4 is fixedly connected to the rotating rod 5 through a coupling. The rotating rod 5 passes through the premixing tank 3 and the feeding pipe 7, and the lower end of the rotating rod 5 extends into the stirring and mixing tank 1. The first stirring rod 6 and the second stirring rod 9 are both provided with multiple groups. The multiple groups of the first stirring rod 6 and the second stirring rod 9 are all fixedly connected to the surface of the rotating rod 5. The first stirring rod 6 is arranged in the premixing tank 3, and the second stirring rod 9 is arranged in the stirring and mixing tank 1.

[0031] It is worth mentioning that when the drive motor 4 works, the output shaft of the drive motor 4 rotates to drive the rotating rod 5 to rotate, so that when the rotating rod 5 rotates, the first stirring rod 6 and the second stirring rod 9 are driven to rotate, so that the first stirring rod 6 and the second stirring rod 9 can achieve stirring and mixing of the raw materials;

[0032] The stirring and mixing tank 1 is provided with a controller, and the driving motor 4, the pressure sensor 19 and the solenoid valve 22 are all electrically connected to the controller;

[0035] It is worth noting that when the rotating rod 5 rotates, the anti-blocking plate 8 can be driven to rotate, so that the anti-blocking plate 8 prevents the raw material from being blocked in the feeding pipe 7;

[0036] A scraper 10 is fixedly connected to the surface of a set of second stirring rods 9, and the scraper 10 is in contact with the inner bottom of the stirring and mixing tank 1;

[0037] It is worth mentioning that the scraper 10 can be driven to rotate when the rotating rod 5 rotates, so that the scraper 10 can scrape the mortar at the bottom of the mixing tank 1, thereby facilitating the discharge of the mortar;

[0038] The bottom of the stirring and mixing tank 1 is connected to a discharge pipe 12, and a discharge valve 13 is provided on the discharge pipe 12;

[0040] A support frame 2 is fixedly installed on the top of the stirring and mixing tank 1, and a pre-mixing tank 3 is fixedly installed on the support frame 2;

[0041] In specific use, by pouring the raw materials into the premixing tank 3, after the weight of the raw materials is detected by the pressure sensor 19, the signal can be fed back to the controller, and the controller detects the weight of the raw materials to detect the proportion of the raw materials. The controller controls the solenoid valve 22 to open, so that the raw materials can be transported to the premixing tank 3 after passing through the plug-in tube 21 and the feed pipe 15. When the raw materials are transported, the weight of the raw materials in the premixing tank 3 will decrease. After the raw materials are put into a suitable proportion, the controller controls the solenoid valve 22 to close;

[0042] When the raw materials are put into the premixing tank 3, the controller controls the driving motor 4 to work, and the output shaft of the driving motor 4 rotates to drive the rotating rod 5 to rotate, so that the rotating rod 5 drives the first stirring rod 6 and the second stirring rod 9 to rotate when rotating. The raw materials in the premixing tank 3 can be pre-mixed by the first stirring rod 6, thereby improving the mixing efficiency of the raw materials. The raw materials after pre-mixing can fall into the mixing tank 1 through the discharge pipe 7, and the raw materials are stirred and mixed again by the second stirring rod 9. After the raw materials are formed into mortar, the mortar can be discharged by opening the discharge valve 13.

[0043] In the present application document, the control method of the driving motor 4, the pressure sensor 19 and the solenoid valve 22 is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field, which is common knowledge in the field, and the present application document is mainly used to protect the structure and shape and their combination, so the present application document will no longer explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
