It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0044] Example 1:

[0045] This embodiment provides a lifting mortar mixing device, including a frame 1, a mixing bucket 2 mounted on the frame 1, and a stirring mechanism 3 mounted on the frame 1. The stirring mechanism 3 includes:

[0046] The stirring shaft 31 is vertically arranged in the stirring barrel 2;

[0047] A plurality of first stirring blade groups 32 are arranged on the stirring shaft 31 , and the first stirring blade group 32 includes a fixing ring 321 provided on the stirring shaft 31 and two first blades 322 symmetrically provided on the fixing ring 321 ;

[0048] A plurality of second stirring blade groups 33 are located between two adjacent first stirring blade groups 32 , and the second stirring blade group 33 includes a rotating ring 331 rotatably connected to the stirring shaft 31 and two second blades 332 symmetrically arranged on the rotating ring 331 ;

[0049] A driving mechanism 34 is provided on the top of the mixing barrel 2 and is used to drive the mixing shaft 31 to rotate;

[0050] Among them, the stirring shaft 31 is sleeved with a sleeve 35, and a plurality of arc-shaped limiting holes 6 are arranged on the sleeve 35. The arc-shaped limiting holes 6 are arranged through the sleeve 35, and the second blade 332 passes through the arc-shaped limiting holes 6 and is connected to the rotating ring 331. The sleeve 35 is also provided with a plurality of limiting through holes 7, which are arranged through the sleeve 35. The limiting through hole 7 is located between two adjacent arc-shaped limiting holes 6. The first blade 322 passes through the limiting through hole 7 and is connected to the fixing ring 321. The first blade 322 and the second blade 332 are both provided with a scraping portion 8 that contacts the inner wall of the stirring barrel 2 at one end close to the inner wall of the stirring barrel 2.

[0051] In this technical solution, the mixing barrel 2 can be a cylindrical barrel structure made of metal, and the inner wall of the mixing barrel 2 is smooth. The mixing barrel 2 is vertically arranged and has a feed port on the top, and the mortar raw materials can enter the mixing barrel 2 from the feed port.

[0052] The stirring mechanism 3 is used to stir the mortar raw materials in the stirring barrel 2 so that the mortar raw materials are evenly mixed.

[0053] The fixing ring 321 is sleeved on the stirring shaft 31 and can be fixed to the stirring shaft 31 using countersunk screws to prevent the fixing ring 321 from rotating. The first blades 322 are fixed to the fixing ring 321 using screws. Multiple first stirring blade groups 32 are arranged from top to bottom on the stirring shaft 31 so that the multiple first blades 322 are maintained on a vertical plane. The first blades 322 can be a vertical plate-like structure or a horizontal rod-like structure.

[0054] The rotating ring 331 is mounted on the stirring shaft 31 and rotates on the stirring shaft 31. The second blades 332 can be fixed to the rotating ring 331 using screws. Multiple second stirring blade groups 33 are arranged from top to bottom on the stirring shaft 31, and the second blades 332 are located between two adjacent first blades 322. The second blades 332 can be a vertical plate-like structure, or a horizontal rod-like structure or an arc-shaped structure.

[0055] The sleeve 35 and the agitator shaft 31 can be secured by fasteners, ensuring that they do not rotate relative to each other. The sleeve 35 is provided with a plurality of arc-shaped limiting holes 6, each having a 90-degree arc. Each arc-shaped limiting hole 6 can include a leading end and a trailing end, with the leading end facing the limiting through-hole 7. The arc-shaped limiting holes 6 can limit the rotation angle of the rotating ring 331, thereby limiting the rotation angle of the second blade 332, ensuring that the second blade 332 can reciprocate 90 degrees within the arc-shaped limiting holes 6.

[0056] The driving mechanism 34 is located above the stirring barrel 2 . The driving end of the driving mechanism 34 is connected to the top of the stirring shaft 31 to drive the stirring shaft 31 to rotate. The stirring shaft 31 drives the first blade 322 and the second blade 332 to rotate.

[0057] Initially, one end of the second blade 332 connected to the rotating ring 331 is located at the head end of the arc-shaped limiting hole 6 , so that the second blade 332 and the first blade 322 are kept in the same vertical plane.

[0058] When the driving mechanism 34 drives the stirring shaft 31 to rotate forward, for example, clockwise rotation is defined as forward rotation, the first blade 322 rotates clockwise, while the second blade 332 remains stationary due to the resistance of the mortar raw material. When the stirring shaft 31 rotates 90 degrees, the end of the second blade 332 connected to the rotating ring 331 is located at the end of the arc-shaped limiting hole 6. At this time, the first blade 322 and the second blade 332 are 90 degrees apart. As the stirring shaft 31 continues to rotate, the end of the second blade 332 connected to the rotating ring 331 remains located at the end of the arc-shaped limiting hole 6, and the first blade 322 and the second blade 332 are always perpendicular to each other, thereby improving the uniformity of stirring and enhancing the stirring effect.

[0059] After stirring is finished, the mortar in the mixing barrel 2 can be taken out. The material can be discharged by setting a discharge port at the bottom of the mixing barrel 2, or a suction pipe can be placed at the feed port to suck out the mortar.

[0060] After the mortar in the mixing barrel 2 is taken out, the inner wall of the mixing barrel 2 needs to be cleaned to prevent the mortar from hardening on the inner wall of the mixing barrel 2 and affecting the next use of the mixing device.

[0061] The stirring shaft 31 can be driven to rotate in the opposite direction by controlling the driving mechanism 34. At this time, the first blade 322 rotates counterclockwise, and the second blade 332 is affected by the resistance of the inner wall of the stirring barrel 2. The second blade 332 remains stationary, and the end of the second blade 332 connected to the rotating ring 331 is still located at the tail end of the arc-shaped limiting hole 6.

[0062] After the stirring shaft 31 rotates 90 degrees in the opposite direction, the end of the second blade 332 connected to the rotating ring 331 is located at the beginning of the arc-shaped limiting hole 6. At this time, the first blade 322 and the second blade 332 remain in a vertical plane. As the stirring shaft 31 continues to rotate, the end of the second blade 332 connected to the rotating ring 331 remains at the beginning of the arc-shaped limiting hole 6. The first blade 322 and the second blade 332 always remain in the same plane, and the adjacent scraping portions 8 are in contact with each other.

[0063] The scraping portion 8 that contacts the inner wall of the mixing barrel 2 scrapes off the residual mortar on the inner wall of the mixing barrel 2. The scraped mortar falls to the bottom along the inner wall of the mixing barrel 2, and the mortar at the bottom is recovered to avoid affecting the next use and avoiding waste of residual mortar.

[0064] The scraping portion 8 can be fixed to the ends of the first blade 322 and the second blade 332 using screws, and the scraping portion 8 can be made of plastic or rubber.

[0065] The present invention further includes a control system, which may be an existing conventional system for controlling the operation of the stirring mechanism 3 , wherein the control system may be a PLC control system.

[0066] Furthermore, the mixing barrel 2 includes:

[0067] The barrel body 21, the stirring shaft 31 is arranged in the barrel body 21;

[0068] A barrel cover 22 is provided on the top of the barrel body 21;

[0069] The driving mechanism 34 is disposed on the top of the barrel cover 22 .

[0070] In this technical solution, the barrel cover 22 is arranged on the top of the barrel body 21, the feed port can be arranged on the barrel cover 22, and the discharge port can be arranged at the bottom of the barrel body 21.

[0071] The bucket cover 22 can be connected to the barrel body 21 by fasteners, such as screws. The bucket cover 22 can be provided to prevent dust from polluting the environment and to prevent dust generated during the mixing process from affecting the health of the construction workers.

[0072] Furthermore, the driving mechanism 34 includes:

[0073] The first driving motor 341 has a driving end connected to the top end of the stirring shaft 31 .

[0074] In this technical solution, the first drive motor 341 may be a conventional motor with an output shaft, and the drive end of the first drive motor 341 may be connected to the stirring shaft 31 by using a coupling.

[0075] Example 2:

[0076] This embodiment provides a lifting mortar mixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0077] Two arc-shaped limiting grooves 9 are provided on both ends of the fixed ring 321 , and sliding protrusions 10 are provided on the top and bottom of the rotating ring 331 . The sliding protrusions 10 are arranged in the arc-shaped limiting grooves 9 and slide in the arc-shaped limiting grooves 9 .

[0078] In this technical solution, the arcuate limiting groove 9 has the same curvature as the arcuate limiting hole 6. The sliding protrusion 10 is disposed within the arcuate limiting groove 9, allowing the rotating ring 331 to rotate within the angle limited by the arcuate limiting groove 9. For example, if the arcuate limiting groove 9 is 90 degrees, the rotating ring 331 can drive the second blade 332 to rotate 90 degrees. The arcuate limiting groove 9 is used to further limit the rotating ring 331, preventing the second blade 332 from colliding with the arcuate limiting hole 6, which would cause wear on the second blade 332 and the arcuate limiting hole 6, and further improving the rotation stability of the rotating ring 331.

[0079] Example 3:

[0080] This embodiment provides a lifting mortar mixing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0083] The support frame 12 is mounted on the base 11, and the barrel cover 22 is mounted on the support frame 12;

[0084] There are multiple casters 13 , all mounted on the bottom of the base 11 .

[0085] In this technical solution, there are at least four casters 13, which are installed at the bottom of the base 11 to facilitate the movement of the stirring device and improve the convenience of use.

[0088] It also includes a first lifting mechanism 4, which includes:

[0089] Two lifting hydraulic cylinders 41 are installed on the base 11 , and driving ends of the two lifting hydraulic cylinders 41 are respectively connected to two sides of the barrel body 21 .

[0090] In this technical solution, the lifting hydraulic cylinder 41 can be a conventional hydraulic cylinder with a telescopic effect, which has the effects of stable operation and large load.

[0091] When the stirring mechanism 3 is to be cleaned or the stirring mechanism 3 and the stirring barrel 2 need to be repaired, the barrel body 21 and the barrel cover 22 need to be separated, the fasteners between the two can be removed, and then the driving end of the lifting hydraulic cylinder 41 can be controlled to descend, so that the barrel body 21 is lowered, which is convenient for cleaning the stirring mechanism 3 and repairing the stirring mechanism 3 and the stirring barrel 2.

[0092] When the barrel body 21 and the barrel cover 22 need to be connected, the barrel body 21 can be raised by controlling the driving ends of the two lifting hydraulic cylinders 41 to rise, and then the barrel body 21 and the barrel cover 22 are connected by fasteners.

[0093] When the lifting mechanism is in operation, the stirring mechanism 3 stops operating to prevent the first blade 322 and the second blade 332 from rotating and causing injuries to people.

[0099] The barrel body 21 is mounted on the screw nut 512 .

[0100] In this technical solution, the second drive motor 52 can be a conventional motor with a rotating output shaft. By controlling the second drive motor 52 to drive the screw rod 511 to rotate, the screw nut 512 is raised and lowered, thereby controlling the raising and lowering of the barrel body 21. This facilitates the separation of the barrel body 21 from the barrel cover 22, the cleaning of the stirring mechanism 3, and the maintenance of the stirring mechanism 3 and the stirring barrel 2.
