[0002] A mixer is a kind of construction machinery, mainly used for mixing cement, sand, various dry mortar and other construction materials. The working principle of a mixer is to mix a variety of raw materials into a mixture or a machine with suitable consistency by rotating a shaft with blades in a cylinder or trough. Mixers are classified in many ways according to their uses and structures. According to the working mode, they can be divided into forced mixers, single-shaft mixers, twin-shaft mixers, etc. According to the mixing mode, they can be divided into paddle mixers, turbine mixers and spiral mixers. Mixers are widely used in many fields, especially in construction projects. Mortar mixers are an indispensable and important equipment used to mix raw materials such as cement, sand, and water into uniform mortar.

[0003] However, traditional mortar mixers often have problems such as uneven mixing, complicated operation, and inability to adapt to mixing requirements at different heights. In order to solve these problems, we propose a liftable mortar mixer. Utility Model Content

The rotating shaft of the driving motor 8 extends into the inner cavity of the driving device box 7 and is fixedly connected to the stirring rotating main shaft 13. The lower end of the stirring rotating main shaft 13 is rotatably connected to the bottom inner wall of the driving device box 7. The lower end of the side of the stirring rotating main shaft 13 is fixedly connected to the gear 14. Two ends of the lower side surface of the driving device box 7 are rotatably connected to two symmetrically arranged stirring rods 15. Both stirring rods 15 extend into the inner cavity of the driving device box 7 and are fixedly connected to the gear 14. The gears 14 at the top of the two stirring rods 15 are meshed with the gear 14 at the lower end of the stirring rotating main shaft 13.

[0030] Furthermore, the stirring device 20 includes an agitator 16, a stirring blade 17 and a stirring connecting plate 18. The lower ends of the sides of the two stirring rods 15 are fixedly connected with the agitator 16. The agitator 16 is a square frame.

[0034] Working principle: First, the equipment is firmly placed on the work site through the base 1, and the connecting counterweight block 2 is fixedly connected to one side of the base 1 to provide necessary counterweight for the entire equipment, ensuring the stability of the equipment during the lifting process. The sliding sleeve 3 is fixedly connected to the upper surface of the base 1 near one end of the connecting counterweight block 2 to form a support frame of the lifting structure. The sliding support rod 4 is movably inserted in the sliding sleeve 3 to allow it to move freely in the vertical direction. The hydraulic top 5 is fixedly connected to the upper end of the side of the sliding sleeve 3. By controlling the extension and contraction of the hydraulic top 5 and squeezing the connecting block 12 upward, the sliding support rod 4 can be lifted and lowered in the sliding sleeve 3, so that the stirring device 20 can be driven to be lifted and lowered through the driving device box 7. When using this device for stirring, the driving motor 8 is turned on and the stirring rotating spindle 13 is driven to rotate by the driving motor 8, thereby driving the stirring rotating spindle. The gear 14 fixedly connected at the lower end of 13 rotates, and the three gears 14 start to rotate, so that the stirring rods 15 at the lower ends of the gears 14 on both sides start to rotate. The rotation of the stirring rods 15 drives the two stirrers 16 to rotate. The mortar is fully stirred by the rotation of the stirrer 16 and the action of the stirring blades 17. The stirring blades 17 are inclined, and the stirring blades 17 at both ends of the same stirrer 16 are inclined in opposite directions, which helps to generate greater stirring force during rotation and make the mortar mixed more evenly. At the same time, the stirring connecting plate 18 at the bottom of the stirring rod 15 is rotatably connected to the extension sleeve 11. When the stirring device 20 moves upward, the spring 10 in the inner cavity of the extension sleeve 11 extends upward to drive the extension sleeve 11 to always keep in contact with the bottom of the stirring connecting plate 18, which can ensure the stability of the entire stirring device 20 when stirring at different upper and lower positions.
