DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model is a self-cleaning cement mortar mixer, comprising a tank body 1 and a top cover 2, wherein a discharge pipe 3 is provided at the lower end of the tank body 1, the top cover 2 is located at the upper end of the tank body 1, a first motor 4 is fixedly arranged at the upper end of the top cover 2, a fixed seat 5 is fixedly arranged at the lower end of the top cover 2, a rotating shaft 6 penetrating the fixed seat 5 is provided at the output end of the first motor 4, a first rotating block 7 is fixedly arranged at the lower end of the rotating shaft 6, a plurality of first stirring rods 8 are provided on the circumference of the first rotating block 7, a second rotating block 9 is rotatably arranged on the top of the fixed seat 5, a plurality of second stirring rods 10 are provided on the circumference of the second rotating block 9, the second stirring rod 10 is located on the outer side of the first stirring rod 8, a plurality of scraping rods 17 contacting the inner wall of the tank body 1 are provided on the outer side of the second stirring rod 10, a transmission wheel 11 is rotatably arranged on one side of the fixed seat 5, and the transmission wheel 11 is respectively meshed with the first rotating block 7 and the second rotating block 9;

[0024] When the present structure is in use, cement mortar material is added into the tank body 1, and then the top cover 2 is lowered to the top of the tank body 1. At this time, the position of the cement mortar in the tank body 1 will not be higher than the first rotating block 7. The first motor 4 is started, so that the rotating shaft 6 can drive the first rotating block 7 to rotate, and the first rotating block 7 can drive the first stirring rod 8 to rotate clockwise. Through the meshing effect, the first rotating block 7 can drive the second rotating block 9 to rotate counterclockwise through the second stirring rod 10, so that the second rotating block 9 can drive the second stirring rod 10 to rotate counterclockwise on the outside of the first stirring rod 8, thereby improving the mixing quality and mixing efficiency of the cement mortar material in the tank body 1.

[0025] When the second stirring rod 10 rotates, the scraper rod 17 moves on the inner wall of the tank body 1, which can provide a scraping effect for the material on the inner wall of the tank body 1, making it difficult for the material to stick to the inner wall of the tank body 1, and making the inner wall of the tank body 1 easy to clean.

[0026] Furthermore, a positioning shaft is fixedly arranged in the middle part of the transmission wheel 11, one end of the positioning shaft is connected to the rotation, and the second rotating block 9 is located at the top of the transmission wheel 11, and the first rotating block 7 is located at the bottom of the transmission wheel 11. The positioning shaft can provide a support for the transmission wheel 11, which can improve the stability of the transmission wheel 11 during rotation.

[0027] Furthermore, the scraper rod 17 can be fixed on the outer side of the second stirring rod 10 through a support rod.

[0028] In this structure, the sizes of the plurality of first stirring rods 8 are the same, the sizes of the plurality of second stirring rods 10 are the same, and the sizes of the plurality of scraping rods 17 are the same.

[0029] When it is necessary to add material to the inside of the tank body 1, it is necessary to raise the top cover 2. A plurality of guide blocks 13 are symmetrically arranged on the top of the tank body 1. Guide rods 12 penetrating the guide blocks 13 are symmetrically arranged on both sides of the top cover 2. A second motor 14 is fixedly arranged on one side of the tank body 1. A side block 16 is arranged on one side of the top cover 2. A screw 15 penetrating the side block 16 is arranged at the output end of the second motor 14. The screw 15 is threadedly connected with the side block 16. Starting the second motor 14 can rotate the screw 15. Through the action of the threaded structure, the side block 16 can rise along the screw 15, so that the top cover 2 can rise on the top of the tank body 1. At this time, the guide rod 12 will rise at the guide block 13, which can make the top cover 2 more stable during the rising process. When the feeding is completed, the second motor 14 is started to reverse the screw 15, so that the top cover 2 can be reset. When the material is stirred in the tank body 1, the valve on the discharge pipe 3 is opened, and the material in the tank body 1 is discharged to the specified position through the discharge pipe 3. The structure is simple and the operation is convenient.

[0030] Furthermore, both the first motor 4 and the second motor 14 can be servo motors.
