[0026] In a specific embodiment, Figures 1 to 9As shown, the cleaning assembly 7 includes a first scraper 701, a second scraper 702 and a third scraper 703. The cleaning assembly 7 and the stirring assembly 6 are staggered on the rotating shaft 10. The first scraper 701 is vertically installed between the second stirring blades 603, and a plurality of first scrapers 701 are provided. The front end surface of the first scraper 701 is in contact with the inner wall of the stirring drum 1.

The second limiting column 707 is installed on the inner side of the L-shaped structure of the first scraper 701, and the second limiting column 707 is far away from the inner wall of the first scraper 701. When stirring, when the second stirring blade 603 drives the first scraper 701 to rotate, under the action of the mortar, the first scraper 701 rotates around the first rotating column 708, so that the front end of the first scraper 701 is separated from the inner wall of the mixing drum 1, reducing the first scraper 701 from scratching the inner wall of the mixing drum 1.

After the first fixed column 7010 is rotated around the second rotating column 709, it is in contact with the inclined surface of the groove. When the second scraper 702 rotates forward on the rotating shaft 10, the first fixed column 7010 rotates the second scraper 702 around the second rotating column 709 under the action of the mortar. There is a gap between the first fixed column 7010 and the support rod 704, which causes the second scraper 702 to rotate, so that the front end of the second scraper 702 is separated from the inner wall of the inner arc of the mixing drum 1, and the second scraper 702 does not work.When the rotating shaft 10 rotates in the reverse direction, under the action of the mortar, the second scraper 702 rotates around the second rotating column 709, and there is no gap between the first fixed column 7010 and the support rod 704, so that the second scraper 702 cannot rotate, and the front end of the second scraper 702 is in contact with the inner wall of the inner arc of the mixing drum 1, and the second scraper 702 scrapes the mortar off the inner wall of the mixing drum 1.

Start the vibration motor 503, there is a gap between the outer side of the screen frame 501 and the inner cavity of the hopper 401, and the vibration motor 503 will drive the screen frame 501 to shake under the action of the spring 504, accelerating the raw materials to fall from the screen 502. When loading, the sand and cement are screened separately to prevent large particles of sand or agglomerated sand from entering the mixing drum 1 and damaging the mixing blades. However, due to unreasonable stacking of cement, cement may form a block, and it is not easy to mix evenly if it enters the mixing drum 1 directly, and large cement blocks will also damage the mixing blades. Therefore, the raw material particles falling into the hopper 401 must be uniform after being screened through the screen 502, so that stirring is convenient. The bottom end of the screen frame 501 extends into the inner cavity of the hopper 401, so that all the screened raw materials fall into the hopper 401. The lower end of the hopper 401 is an eccentric conical structure, and the lowest end of the conical structure is connected to the barrel 404. Start the second motor 407, the second motor 407 drives the screw rod 403 to rotate, and the screw rod 403 will drive the raw material to move upward, so that the raw material falls from the discharge port 408 into the loading port 11 at the upper end of the mixing drum 1. A dust cover 12 is provided at the upper end of the loading port 11, and one side of the dust cover 12 is open. The lower end of the loading port 11 passes through the barrel cover 2 and extends into the mixing drum 1, reducing the impact of the dust raised by the raw materials during loading on the operator. When adding raw materials, first set the raw material ratio and the input amount of raw materials according to the production requirements and the size of the volume of the mixing drum 1. A weighing module 16 is installed at the lower end of the supporting foot of the mixing drum 1. The weighing module 16 is connected to the controller 15. The number of input raw materials will be displayed on the controller 15, and the input will stop after reaching the set value. Sand and cement are respectively put into the mixing drum 1. Start the first motor 9, and the first motor 9 drives the rotating shaft 10 to rotate clockwise, so that the stirring assembly 6 installed on the rotating shaft 10 rotates. First, the cement and sand are mixed evenly by the stirring assembly 6. The stirring assembly 6 includes a first stirring blade 602, a second stirring blade 603 and a third stirring blade 604. The first stirring blade 602 is a single helical structure and the inner wall is in contact with the outer wall of the rotating shaft 10. The first stirring blade 602 mixes and stirs the raw materials from the middle. The second stirring blade 603 is a double helical structure and is installed near the inner wall of the mixing drum 1, which is suitable for mixing the raw materials outside the mixing drum 1. The third stirring blade 604 is installed at the bottom end of the rotating shaft 10 and is located at the bottom end of the mixing drum 1. When rotating, the raw materials at the bottom end roll upward. Under the coordinated stirring of the first stirring blade 602, the second stirring blade 603 and the third stirring blade 604, the mixing of the raw materials is accelerated. During stirring, the cleaning component 7 installed on the stirring component 6.When rotating clockwise, the resistance of raw material stirring causes the first scraper 701, the second scraper 702 and the third scraper 703 to rotate along their respective rotating columns. A limit is set on one side of the first scraper 701, the second scraper 702 and the third scraper 703, so that the front end of the rotation angle can fall off the inner wall of the mixing drum 1, reducing the wear of the inner wall of the mixing drum 1 on the first scraper 701, the second scraper 702 and the third scraper 703. After the raw materials are mixed, the water inlet valve 803 is opened, and water is added to the mixing drum 1. During the adding process, the water and the raw materials are continuously stirred so that the water and the raw materials are quickly mixed. The water meter 804 will detect the amount of water added. After reaching the set value, the water inlet valve 803 is closed. The first motor 9 drives the stirring assembly 6 clockwise to continue stirring and stir the mixture of raw materials and water evenly. When the mortar in the mixing drum 1 is evenly stirred, the first motor 9 is restarted and the first motor 9 is rotated counterclockwise. The discharge valve 14 is opened to discharge the stirred mortar from the discharge port 13. During the discharge, the stirring assembly 6 continues to work, and the stirring assembly 6 will drive the cleaning assembly 7 installed thereon to work. When the rotating shaft 10 rotates counterclockwise, the resistance of the mortar causes the first scraper 701, the second scraper 702 and the third scraper 703 to rotate counterclockwise along their respective rotating columns. However, the first scraper 701, the second scraper 702 and the third scraper 703 are respectively provided with a limiter on one side to limit their reverse rotation, so that they cannot rotate, resulting in the front end of the first scraper 701, the second scraper 702 and the third scraper 703 being attached to the inner wall of the mixing drum 1. The first scraper 701 hangs off the mortar on the inner wall of the mixing drum 1 to prevent it from sticking to the drum wall. The second scraper 702 and the third scraper 703 scrape off the mortar sticking on the inner wall of the inner arc of the mixing drum 1 and the inner wall of the lower end taper. When the mortar in the mixing drum 1 is discharged, the discharge valve 14 is closed. The water inlet valve 803 at the upper end is opened, and a rotating high-pressure nozzle 802 is installed at the end of the water inlet pipe 801. The rotating high-pressure nozzle 802 will spray and rinse the inner wall of the mixing drum 1, the first stirring blade 602, the second stirring blade 603 and the third stirring blade 604. The stirring assembly 6 continues to work, and the first scraper 701, the second scraper 702 and the third scraper 703 installed on the stirring assembly 6 continuously scrape the inner wall to clean the mixing drum 1, the first stirring blade 602, the second stirring blade 603 and the third stirring blade 604. Close the water inlet valve 803, open the discharge valve 14, and discharge the sewage after flushing the mixing drum 1 from the discharge port 13 before stopping the first motor 9. Avoid the residual mortar solidifying and affecting the next stirring, and the solidified mortar will damage the stirring blades and scrapers, resulting in the replacement of the stirring blades and scrapers, which wastes costs.
